Managing information efficiently is a game-changer, especially if you want to save time and enjoy your hobby. As a YouTuber, I’ve developed some simple routines that make it easier to find what you need without constantly searching for things you’ve already come across. These tips aren’t just for the hobby—they can also help streamline your day job. Sound interesting? Let’s get into it!

LoRa modulation is used in many applications, like LoRaWAN or Meshtastic. Another application, a LoRa 1:1 link, can be beneficial because it inherits all the good properties, like long distance and low power. It is simple, does not need an infrastructure, and can be used bi-directionally. Because I want to build a long-range bidirectional mailbox notifier, I will evaluate a few LoRa boards, connect them to an ESP32 and an ATTINY1614, and finally integrate them via MQTT into Home Assistant.

This is a replay of video 425 (During my summer break) Today, working with GitHub is a fundamental skill. Most libraries and projects reside on GitHub, and we must know how to use them. GitHub can also enhance our work procedure, and a lot of employers will ask you for your GitHub account or will check it out before they invite you for an interview. So, GitHub seems at least as crucial as LinkedIn for a professional developer’s career. This video will teach you the basics of using GitHub for your Arduino projects. And I promise: We will avoid the command line!

This is a replay of the video 403 (during my summer break) SD cards in Raspberry Pi computers wear out and die after a while because they are not made for computer usage, and many write cycles. In addition, the SD cards can become corrupted if the Pi loses power without a proper shutdown. We have several possibilities to avoid this disaster. Only one is simple and cheap.

When I made my videos about LoRaWAN, some viewers asked if it would replace conventional Wi-Fi with a much bigger range. Unfortunately, this was not the case because LoRa has a huge range but a minimal throughput. It seems somebody listened to them and invented Wi-Fi on the same frequency band as LoRaWAN using Wi-Fi protocols. Cool. In this video, we will check it out to see if it can keep its promises, like going through walls and having a more than 1-kilometer range. We will compare it to standard Wi-Fi and learn that we must pay attention to staying legal.

Switching your Windows or Linux PCs on and off automatically or from a remote location can be important. In this video, you will learn how to do this from Home Assistant, Node-Red, and the Linux shell. As an example, I will save about 99% of the energy used by my Proxmox Backup server because it only runs a few minutes a day. I will also start a Windows PC in our remote radio station—all free of charge, of course. Wake-on-LAN is the “magic” word.

When I saw this video from Louis Rossmann or this one by Tom, a fellow HAM radio operator, I said to myself: Holy shit! I use these car fuses a lot, and I always expected that they protect my circuits from overcurrent and possible burning, but I never checked if they work. Particularly since I started to work with Lithium batteries capable of delivering huge currents and even burning if you are unlucky, the danger increased dramatically.

LoraWAN is a widely used low-power, long-range network that consists of sensors and gateways. I will provide you with an overview and a comparison of the currently available LoRaWAN gateways, as well as how to select them. Because most gateways use the same chips and should have similar ranges, I will not test it. Still, you will see big differences in capabilities, software, and price.

Frequent viewers know that I like GreatScott's channel because he greatly develops people’s interest in electronics. When he showed a trigger board to keep a USB power bank on for small projects, I thought: Great idea, but this could be done better! And it is a perfect excuse to tinker with the new ATtiny chips. He used a 50-year-old 555 timer IC, and I want to use the same size and a similar price modern chip because this chip lets us put some “artificial” intelligence into the project. During this journey, we will learn about a very useful chip family and discover some unknown behavior of power banks as well as a new fake sold on AliExpress.

When I proposed to leave the Raspberry Pi for home server applications, many viewers wrote that Proxmox is now also available on the Pi. The Raspberry Pi 5 is much faster than the Pi4, it comes with 8GB of RAM and, with its low power consumption, should be a perfect fit for a Proxmox server. So, let’s check if this is true. And during this process, you will learn a few tricks for the new Pi5.

Charging and transferring data over USB cables has become much faster over the past years. With the standardization of USB-C connectors, it also became easier, right? Wrong. Because, without precautions, you still will encounter low transfer speeds and slow or even no charging at all. Because the topic is complex, I will divide it into two parts. Today, we will start with Power Delivery. After the two videos, you will understand this new technology and will be able to avoid pitfalls.

Rechargeable batteries last way longer if we do not charge them up to 100% or fully discharge them. This is particularly important for batteries in expensive devices like smartphones or tablets because repairing a defective battery is expensive. It took Apple many years till, finally, the iPhone 15 can automatically stop charging at 80% and so extend the lifetime of your battery considerably. Maybe Android phones were faster. This is the best solution, but today, we will solve the problem for all other devices, including our Dashboard Tablet in the kitchen. As a bonus, I will show you why we have this tablet and what it displays. And I will reveal the secret behind this number.

We all know Wi-Fi. But do you know WiGig? Can you imagine what it is? Invented by Elon Musk, where everything is called “Giga”? No, not really. Still, we will talk about Gigahertz and Gigabit per second. After the video, you will know the next frontier of Wi-Fi. As a bonus, I will tell you the story about why we do not need a license to use Wi-Fi. Spoiler: It is because of microwave ovens.

Lately, many radar sensors have become available for relatively cheap prices. In this video, I will give you an overview of what is available and how they compare. And, of course, we will have a look into how they work and test a few of them. After viewing this video, you should be able to choose the right sensor for your needs. And you should know which are overpriced.

The Raspberry Pi 5 was recently announced. It is faster than the old one, and you can add an SSD with a special adapter. The price went up, and now it needs a beefy power supply.

In 2020, I was the first YouTuber to make a video about “Meshtastic,” created by Kevin Hester. The project name was a merge between Mesh and Fantastic. Already then, I loved the project. But why is it the “most dangerous LoRa project”? Here is the proof: My video was included in a study titled “NETWORK-ENABLED ANARCHY” by an organization featured by the US government under the topic “instructions for encrypted messaging”. So stay tuned when I show you what you can do with it even if you have a normal profession.

This is the last re-run of a video (from 2018). In two weeks, I will be back with a new video. I should have been warned: Some viewers on our summer project were against a gun on the tank. But I did not listen. This video shows what happened and how I was punished. In Switzerland, every adult man is in the army and has his weapon at home. Maybe this is the physiological reason for my choice. I am not a psychologist; I am an engineer. So let's start with the story about How-to build a rail gun or a coil gun. Or how to not do it...

Unfortunately, most soil moisture sensors used in our Arduino, ESP8266, or ESP32 projects destroy themselves after a short while. We need a better solution.

During my summer break, I reupload successful videos of the past (for your rainy Sundays). This one aired on April 5th, 2020. Measuring current is simple. Right? You just take a multimeter, connect it to the two cables, and read the value. If you want to do the same with a Microcontroller like an Arduino or an ESP, things get a little more complicated.

The invention of radar influenced the way world war two went, because it was possible to detect planes of the enemy and shoot them down. And since then, this technology made civil aviation as we know it possible, because it can detect movement of metallic surfaces over distance. Of course, the technology can also be used against us, for example if we are trapped while speeding… Links: HW-MS03: https://s.click.aliexpress.com/e/_DkUq8bF RCWL-0516 (Works also with 3.3 volts): https://s.click.aliexpress.com/e/_DkUq8bF XYC-WB-D1: https://s.click.aliexpress.com/e/_DDbqgWh HFS-DC06:https://s.click.aliexpress.com/e/_DEAbjz7 220V Switch (SK-600): https://s.click.aliexpress.com/e/_DF7AWOD http://www.rogerclark.net/investigating-a-rcwl-9196-rcwl-0516-radar-motion-detector-modules/ https://github.com/jdesbonnet/RCWL-0516/ Big Clive: https://youtu.be/Hf19hc9PtcE

Do I need optimizers or microinverters for my PV system? Solar Edge and Enphase, the two most prominent companies in this field, say “yes” and sell many of these little devices. They also explain why they are absolutely needed. But is this true, or are these optimizers only needed to fill the pockets of the manufacturers?

Detecting humans is one of the biggest challenges in Home Automation. Most of us use PIR sensors for that purpose. Unfortunately, they do not detect presence without movement and switch off. Who wants that the TV switches off when you quietly watch a video? Recently, new radar sensors appeared that solve this problem. But they have a slow reaction when you enter the room. Some YouTubers suggest combining such a sensor with a PIR. An expensive workaround.

Raspberry Pis are very good for monitoring all sorts of things. Today we will use InfluxDB and Grafana for monitoring as well as enable Telegram and Mail alarming. In the end, we will “harden” the Raspberry so that it automatically restarts tasks after they crashed.

“Which transistor will work with my project?” Mouser alone lists different 37000 types. We will reduce this number to a “survival kit” for our lab. To do that, we give a little background and do some experiments. In this video we will: - Focus on Arduino and ESP projects - Look at the technology behind the transistors to distinguish the needed from the “nice-to-have” - Do some tests in typical applications - And finally, provide rules of thumb and a “survival kit” for your lab My second channel: https://www.youtube.com/channel/UCQwyP4Yd0-O49e05kMUJgQQ Links: N-Channel: IRF3708 (TO-220) https://s.click.aliexpress.com/e/_DCdJWBV Si2302DS (SMD) http://s.click.aliexpress.com/e/_s7Z334 P-Channel: NDP6020P (TO-220) http://s.click.aliexpress.com/e/_rvulr8 Si2301 (SMD) http://s.click.aliexpress.com/e/_sAd55C Transistor Curve Tracer: https://amzn.to/3biWrUl or https://ebay.us/7BHfW2 The links above usually are affiliate links that support the channel (no additional cost for you).

Today, working with GitHub is a fundamental skill. Most libraries and projects reside on GitHub, and we have to know how to use them. GitHub can also enhance our work procedure, and a lot of employers will ask you for your GitHub account or will check it out before they invite you for an interview. So GitHub seems to be at least as important as LinkedIn for a professional developer’s career. This video will teach you the basics to start with GitHub and use it for your Arduino projects. And I promise: We will avoid the command line!

A well-kept secret of the ESP32 is its extended audio capabilities because it is hard to use. Luckily, I found a library and a toolset enabling us to easily use these capabilities. We now can connect microphones, loudspeakers, Bluetooth loudspeakers, SD cards, and even browsers to an ESP32 to record and play sound. Very handy for all sorts of projects. And we will build an internet radio with a single line of code in the loop(). I am a proud Patreon of @GreatScott! , @Electronoobs , @EEVblog , and others.

Oscilloscopes and signal generators are handy tools in our labs. Unfortunately, they are not cheap. What if you had such devices already and did not know? All newer PCs have loudspeakers and a microphone. So they can create sound as well as record it. And usually in decent quality. Like oscilloscopes and signal generators! We only need a connection and software to create the desired waveforms and visualize the measured voltages. Fortunately, such software is available. And the best: We can use it free of charge!

Measuring levels of liquids is a common problem. Where I live, it is probably more the water level of the coffee machine, in rural areas the level of a water tank, and in the industry the level of chemical substances. There are many different ways to get this job done. If you stick around, I will show you ten different sensors and, as usual, we will learn some new tricks. - Sensors that react on fluid level thresholds - Sensors that measure the fluid level - Sensors that have to be mounted inside and sensors that are mounted outside the tanks - Sensors for the top and for the bottom of the tanks - And, as usual, you get some background info on the sensor interfaces I am a proud Patreon of @GreatScott!, @ElectroBOOM , @Electronoobs , @EEVblog , and others.

Often viewers ask in the comments: Why do you still use batteries and not supercapacitors for your projects? Good question. Do you know the answer? Supercapacitors are super like Superman or Superwoman. Otherwise, they only would be called “Capacitors.” Right? Where are they “super” and where not? Where can we use them, and how?

Up till now, emulating a keyboard or a mouse was only possible with an Arduino Micro or a USB host shield. With the new Arduino support for the ESP32-S2 I will show you how it can be done with our darling. In addition, we will add Wi-Fi to create remote logging to Excel or other PC software. If you have evil thoughts, you can also use it as a wireless “rubber ducky” to hack other PCs or play a trick with your colleagues. As a bonus, we will deepen our knowledge of how USB works.

Switches or sensors without wires? No problem if you use batteries. But without batteries? The Enocean alliance created a standard for such devices. So let’s have a closer look at switches and sensors that do not need a battery change. And here I have a cheaper Chinese “clone.” How does it compare? And how do these devices compare with Zigbee or BLE switches and sensors? A lot of questions! I am a proud Patreon of @GreatScott!, @ElectroBOOM , @Electronoobs , @EEVblog , and others.

The first cheap chip supporting 5GHz Wi-Fi is the Realtek RTL8720 and it should be Arduino compatible. But is it any good? And which tricks do we need to know? Or is it better to wait for the new ESP32, which should also support 5GHz Wi-Fi? Let’s test it out! And discover that the manufacturer included a multi-level adventure game, free of charge.

LoRa and LoRaWAN are remarkable technologies, they have a long-range and low power consumption and therefore are ideal for our sensor projects. Today I will show you how to build a LoRaWAN sensor and connect it to the open The Things Network in the new version 3. I will also show how you can migrate your infrastructure if you are already a user of the V2 network, where the deadline is this December. In the end, you even will get a surprise.

SD cards in Raspberry Pi computers wear out and die after a while because they are not made for computer usage, and many write cycles. In addition, the SD cards can become corrupted if the Pi loses power without a proper shutdown. We have several possibilities to avoid this disaster. Only one is simple and cheap. But, unfortunately, it has its caveats. So let’s get an overview and use a nearly unknown Raspbian feature to help us solve the problem.

Using a real operating system to simplify programming with the Arduino IDE. Is this possible and how? Let’s have a closer look! Operating systems were invented to simplify our lives. But, because they need a lot of resources, they only run on reasonable computers like the Raspberry Pi or a PC. Right? Wrong. Nowadays, we also get operating systems running on our small MCUs. Particularly interesting in this respect is the ESP32 because it has enough power and memory to accommodate such an additional burden. And the best: It already runs a version of FreeRTOS with all our Arduino sketches, and it is easier than you think. Is this useful?

Satellites are fascinating but costly and therefore only available to governments, the military, and, recently, also billionaires like Elon Musk (SpaceX) or Jeff Bezos (Amazon). Undiscovered for most, there is another trend: Universities and small companies can build and launch satellites. Because most of these satellites use open transmission standards, everybody can listen to them. Today we will look at a hobby project which enables us to do so. In addition, the project uses some innovative concepts, where we can learn a lot for other projects. And it shows what the Maker community can achieve if we want.

We add a reset button to the Pi Pico. In my last video, I complained about the lack of a reset button. I got a few proposals to solve the problem: - We can purchase this button from Pimironi. It connects the “run” pin to ground. Which is all we need to reset the RP2040 chip - We can add a USB cable with an off switch.

When I got these new RISC-V ESP32 boards in my mail, I asked myself: Is this new technology revolutionary as written everywhere? What are the advantages for a typical Maker? Time for a closer look. But pay attention: It will be a rough ride and not for the fainthearted because we will talk about “stacks,” “IP,” “ecosystems,” and a lot about standardization.

In video #300, I postulated that each classroom should have a CO2 sensor against sleepiness. For a few days, we have a second reason that probably created a better business case for your project: The fear of a next lockdown might convince the school and other managers more because CO2 measurements in rooms can also reduce aerosols in the air. I also show why eCO2 sensors are not a good idea for this purpose.

3D printers are great. Today we will focus on remote controlling our printer with a Raspberry Pi, OctoPrint, a camera, and a Sonoff. But, as usual, we will go a little further than the ordinary: We will save energy by switching the printer and the Raspberry off when it is idle. Including a safe shutdown, of course.

In video #345 I asked the question whether the ESP32 or the STM32 Bluepill is the better choice. The video created quite some controversy, mainly because I compared the weakest STM32F103 chip with the quite powerful ESP32. Some viewers thought I was unfair and suggested to do a test with more powerful chips like the blackpill. This is what we will do (incl. ESP8266). And we will learn quite a few things about the chances and the weakness of the “STM32duino” project. For example, its capability to do inline debugging. At the end of the video, you will have a good overview and know some tricks to save you a lot of time and hassle.

Which battery operated power supply is best for our project? In this video, I have ten boards for the Raspberry Pi, as well as for Arduino, ESP, and STM32 boards. We will compare their features, find out the differences, and test them. Because of the test results, we will not stop there. We will design our own “SuperPower” branded battery power supply.

In video #321, we looked at DC current sensors. Today we will look at how to measure AC mains currents, which is much more difficult. And more dangerous because it can kill you if you do not pay attention. And, because measuring AC power is useful in home automation, we will also look at how to measure voltage and calculate power. To measure correctly, we have to learn about phase shifts and power factor. And I will tell you the essential rule to live long around high voltages.

We want DC power! For Neopixels, for example. Or for battery charging. Or for radio stations. Our power supply has to be strong and stable. Strong means in this case: More than 60 amperes at 12 volts or so. And, these days, it also has to be good for the environment. But it should cost less than 20 dollars. Including shipping.

When the ESP32 came to the market, it was well equipped: Wi-Fi, Bluetooth, two fast cores, an ultra low power core, lots of pins, etc. One thing, however, was lacking: Native USB support like the SAMD processors, for example.

In this video series, we are building a ground station for a geostationary satellite and try to talk to a guy in Antarctica. It is a bonus series and not directly related to the regular topics of the channel. The last two weeks were rainy and wet here in Switzerland. I have the antenna outside, and I did not want to go there with my delicate equipment. That is why I still was not able to transmit a signal and receiving my voice from space. But I was not lazy! And I got a gift from my wife... I am a proud Patreon of GreatScott!, Electroboom, Electronoobs, EEVblog, and others.

Cool projects are rare. Here I found one I want to show to you. An off-grid personal communicator. It includes a lot of new technologies: ESP32, Smartphones, LoRa, BLE, GPS, Mesh, and as you see, 3D printing. And it solves a problem that could be seen as a human right: Personal SMS style communication everywhere in the world, without the need for any infrastructure, and without mass surveillance. In addition, it shows the location of all your friends in your group on a map on your Smartphone. Everything open source, of course. How cool is that? Even "Sexycyborg" Naomi Wu likes it.

This is a bonus video and not very much related to the usual sensors and microcontrollers. In this series, I want to reach a geostationary satellite and talk to another Swiss guy in Antarctica. If not done so, I strongly suggest you watch the series from the start, as you do it on Netflix. In the last videos, we built a prototype for the transmitter and learned how we could create a receiver out of standard and quite cheap parts. And we heard stations from the QO-100 satellite In today’s video, I try to finish the prototype of the Transmitting part by building a 2.4GHz directional antenna, mount it to the dish, connect it to the power amplifier and try to receive our signal through the receiver in Cornwall. The goal is to hear my own voice from the satellite. Exciting! I am a proud Patreon of GreatScott!, Electroboom, Electronoobs, EEVblog, and others.

In this video, I would like to remind you of a handy ESP32 concept: Over the air or OTA update. A simple and efficient replacement of the Serial cable for devices which are not easily reachable, or for barebone ESP32 modules. And, as usual, I will add a few tricks and helpers. In this video, we will: - Learn how to use ESP32 OTA - Create a basic sketch template for all our new projects - I will show you some tricks like remote debugging - If this simple OTA is not enough, I will show you other frameworks - And, as usual, I included a “one last thing” I am a proud Patreon of GreatScott!, Electroboom, Electronoobs, EEVblog, and others.

When we started our bonus project to communicate via the geostationary satellite QO-100, we created a to-do list: - A high power 2.4GHz transmitter - A sensitive receiver for 10GHz - And an internet connection to the Adalm Pluto In the last video, we built a prototype for the transmitter. We just need an antenna to complete the task. So this week, we will make a cheap first version of the receiver. And hopefully, listen to the first signals from space. And you will learn “PLL.” I am a proud Patreon of GreatScott!, Electroboom, Electronoobs, EEVblog, and others.

This is the next video of the bonus series where we want to build a ground station for the geostationary QO-1100 satellite and contact a station in Antarctica. I will not repeat the content of the previous video. Sot it is highly recommended to watch it first if not already done. But first I have to thank you: I asked if I should continue with the series.

This is the start of a bonus video series and probably not for everybody. We will build a satellite station to reach the geostationary QO-100 Amateur Satellite 36’000km away. In the end, I should be able to talk to other amateurs using this ground station. First, I did not plan to do this video, but many of my viewers asked for it. And, because such a complex project will cover many areas, you might profit from one or the other episode even if you are a typical maker and no Radio Amateur.

The Wemos D1 Mini is my favorite ESP8266 board. It is small, cheap, easy to use, and you get many compatible shields. The prototype shield I like most.

We all know: LoRa works very well for long distances. The traditional boards work on frequencies below 1GHz, and we were able to get connections to of up to 700 km to a balloon and a satellite in orbit 400 km away—cool stuff and highly successful. Last year, Semtech announced a new LoRa chip, which works on the standard 2.4GHz Wi-Fi band. Expectations were high, and when I started to build my “connected light sensor,” I thought, I could use these new boards. Do they fulfill the expectations? I will try to use it for my connected light sensor. I am a proud Patreon of GreatScott!, Electroboom, Electronoobs, EEVblog, and others.

Computers crash if they do not have enough voltage. Li-Ion batteries could explode during charging if they were deeply discharged. How can we prevent such events? We need so-called voltage supervisors. Cheap parts with a big effect, which usually do their job in the dark.

In today’s video, we will - Build the single board computer designed in video #297 - Test it and I will show the two most important debugging tools - Look at how computers were programmed in the ‘70s and ‘80s - Repeat the binary and hexadecimal numbering schemes - Have a look into the CPU architecture - Look at assembler programming and “spaghetti code” -We will see how stacks work - We will have a look at a nice 8085 simulator - And we will build a “sophisticated” blink program Links: Project: http://bit.ly/32DGjnz (EasyEDA) Code: https://github.com/SensorsIot/8085-Computer 8085 Cross Compiler: https://www.sbprojects.net/sbasm/ 8085 Simulator: https://www.sim8085.com/ 8085 programs: https://www.tutorialspoint.com/8085-program-for-running-light-with-delays-using-lookup-table EPROM Programmer: https://s.click.aliexpress.com/e/_d6xqld3 or https://amzn.to/2PvmoSz EPROM Eraser: https://s.click.aliexpress.com/e/_d7c0y09 or https://amzn.to/3ciOCtx 8 LED board: https://s.click.aliexpress.com/e/_d793Nnj Ben Eater does a similar thing: https://www.youtube.com/channel/UCS0N5baNlQWJCUrhCEo8WlA Labels for the chips: https://github.com/Upcycle-Electronics/ChipLabels/blob/master/AndreasSpiess8085/AndySpi8085.pdf The links above usually are affiliate links which support the channel (no additional cost for you).

Spectrum Analyzers are very useful if you work with radios. Unfortunately, they are very expensive. Until recently, when I saw this small device for around 50$. Unbelievable. But is it any good? In this video, we will: - See, what such a spectrum analyzer does and how it works - Have a close look at this cheap device and compare its readings with a more expensive one - See the difference between spectrum analyzers (SSA3032X), Vector Network analyzers (N1201SA), and SDR radios I am a proud Patreon of GreatScott!, Electroboom, Electronoobs, EEVblog, and others.

New: Raspberry OS now natively supports USB/SSD boot! Enough is enough! I waited for more than half a year to boot my new Raspberry Pi 4 from SSD to increase its speed and reduce the chance of losing my valuable data. Today we will change that.

Rumors say that a lot or even most of the active parts like transistors on AliExpress are fake. This would have severe consequences for our purchasing. So, let’s check my randomly purchased transistors to see if this is true and also establish a simple procedure to prevent obvious fakes in the future. In my last video, we discussed transistors, and I mentioned that parts on AliExpress might be faked. This sparked quite some comments, sometimes quite harsh. Today I will show you how you can test your transistors to make sure they fulfill the most important claims of the datasheets. This video is intended for Makers, not for manufacturers of products. To save us money and hassle, we will: - Understand how we can test MOSFETS. They are the cornerstone of our “survival kit.” - Build a simple setup to do the tests - Test my transistors purchased on AliExpress to see how many are faked products - I will propose a simple and fast “incoming inspection” for your AliExpress purchases to avoid you are cheated I am a proud Patreon of GreatScott!, Electroboom, Electronoobs, EEVblog, and others.

“Which transistor will work with my project?” Mouser alone lists different 37000 types. We will reduce this number to a “survival kit” for our lab. To do that, we give a little background and do some experiments. In this video we will: - Focus on Arduino and ESP projects - Look at the technology behind the transistors to distinguish the needed from the “nice-to-have” - Do some tests in typical applications - And finally, provide rules of thumb and a “survival kit” for your lab I am a proud Patreon of GreatScott!, Electroboom, Electronoobs, EEVblog, and others Links: N-Channel: IRF3708 (TO-220) http://s.click.aliexpress.com/e/_sUN3um Si2302DS (SMD) http://s.click.aliexpress.com/e/_s7Z334 P-Channel: NDP6020P (TO-220) http://s.click.aliexpress.com/e/_rvulr8 Si2301 (SMD) http://s.click.aliexpress.com/e/_sAd55C Transistor Curve Tracer incl power supply: https://amzn.to/2O7FY6t or https://ebay.to/2t7YX9Z without power supply: https://amzn.to/3aQWthi CommissionsEarned: The links above usually are affiliate links which support the channel (no additional cost for you).

2020 is still young, and many of us started with good resolutions. One could be, “I want to lose weight.” In this video, we will cover a “nerdy” way to do that. Which is astonishingly successful, What do we use: - A scale that automatically logs its readings into a database - As usual, we will use node-red, influxDB, and Grafana on our Raspberry Pi - An interesting scale - A weight budget to compare. We will create it in Excel - And, of course, a strategy to deal with the misbehavior I am a proud Patreon of GreatScott!, Electroboom, Electronoobs, EEVblog, and others.

Before Christmas, I got a package from Lacuna. It contains this small module that should be capable of transmitting sensor data to a LoRa satellite and last for a few months with this battery. After my last experience with FossaSat-1, I am skeptical. Do you want to accompany me on the journey? We all were disappointed when FossaSat-1 did not work. I would have loved to transfer a LoRa message from a 20 dollar sensor node via satellite to my computer before the turn of the decade. FossaSat-1 showed that many problems have to be solved before we can transfer a message via satellite. But let’s have a quick look at who sent me this package.

Today we will look at a completely new LoRa board. A new Semtech LoRa chip series (SX1261, SX1262, SX1268) and new ASR6501 microprocessor. Is it the best LoRa board ever? And what about the new LoRa chip? Let’s have a closer look. The current LoRa chips from Semtech came to the market in 2013. Earlier this year, they finally announced new chips. So far, we did not see them often on the market. Most used boards still are based on the old chips. Recently, Heltec built this new board using one of these new LoRa chips. To find out if this is the best LoRa board ever, we will: - Compare the new and the old LoRa chips - Look at this new module used on this Heltec board - Check if and how good the Arduino IDE supports it - Measure the output power of the LoRa chip - Measure the power consumption and check if it really is “low power” - And finally, you will get my verdict I am a proud Patreon of GreatScott!, Electroboom, Electronoobs, EEVblog, and others.

Wireless mesh networks are fascinating because they adapt to changing situations and can bridge longer distances than point-to-point connections. Today we will have a look into the standard Zigbee mesh technology, learn its pros and cons, and compare it with Wi-Fi and LoraWAN networks. Mesh networks are a little anarchic, and maybe this is why they are fascinating for many free-thinking Makers. But is this true? To find this out, we will: - Compare mesh networks with star or “hub-n-spoke” networks - Look at the different roles in a mesh network - Look at the pros- and cons of a mesh structure - Enable a Raspberry Pi and a cheap USB dongle to act as a network coordinator - Find a way to chart the network for analysis automatically - Try out various network constellations and see if and how it adapts - Connect the network to Node-Red - And glimpse into other mesh networks I am a proud Patreon of GreatScott!, Electroboom, Electronoobs, EEVblog, and others.

Ordinary Satellite Ground Stations cost millions. We will build one for 20 dollars for the newly launched LoRa satellite. Let’s build it in parallel to the launch of the Electron spacecraft from Rocket Lab. Will it be successful? In my last video, I announced that the 16-year old Julian Fernandez and a small team built FossaSat-1. We will accompany the launch and in parallel, we will build a Ground Station and test it with the real satellite. Will it work?

Satellites are expensive and big and only can be launched by the military, governments, or large corporations. Tomorrow morning, this will change. A 16-year old student and his team will launch a LoRa satellite: FossaSat-1 This is Julian Fernandez with his satellite. His company is called Fossa, an acronym for Free Open Source Software and Aerospace Systems, and his first satellite is, of course, called: Sat-1. According to the plans, it will be launched tomorrow, Friday 6th, 7:56 UTC. It will be on board of an Electron from Rocketlabs, a small rocket which is 12 tons and 17m long. It is optimized for small satellites and will start from New Zealand Links: Latest Launch news: https://twitter.com/RocketLab Live View of start: https://www.rocketlabusa.com/live-stream/ Currently active Ground Stations: https://fossa.apaluba.com/worldmap/ Fossa Homepage: https://fossa.systems/ TTGO 433MHz Board: http://s.click.aliexpress.com/e/Ln2tR2za RFM95 433MHz: http://s.click.aliexpress.com/e/pnwdf6cg #CommissionsEarned: The links above usually are affiliate links which support the channel (no additional cost for you).

Do you sometimes feel tired during meetings? Or do you sometimes have a headache after work? Do you want to change that? Then, this video can be interesting for you because we will measure harmful gases in your environment, which can trigger both. We use one ESP32 and two ESP8266. The sensors are: Winsen MH-Z19, Sensirion SGP30, and SCD30 (Measuring CO2 Tutorial) In this video: - Focus on indoor climate - Focus on gases where the primary cause is humans - Look at CO2 its influence on indoor air quality - See the relationship between CO2 sensors and global warming - Use a second way to assess indoor air: VOC or eCO2 - And we will build sensors to transfer values to Grafana I am a proud Patreon of GreatScott!, Electroboom, Electronoobs, EEVblog, and others.

In many projects (Arduino IDE), we need accurate local time. With our ESP chips, we have some libraries to get NTP time, as I showed in video #67. Most of these libraries do not adjust for daylight-saving or summertime. Today we will change that by using standard ESP functionality. And we will see if Hippies were involved in this matter.

Recently, Arduino released four new products. They all look very similar but use completely different Microcontroller chips. So we have to answer two questions: Do they know what they are doing and is it any good for us Makers? And of course: How do they compare with the ESP32? In this video, we will look at these four boards: - Arduino Nano Every - Arduino Nano 33 IoT - Arduino Nano 33 BLE - Arduino Nano 33 BLE Sense And look into the following topics: - An overview of their capabilities. We will also add a typical ESP32 board for reference - We will have a look into how the Arduino IDE supports a multi-CPU Architecture environment - We will look at the new 3.3-volt world and the dangers coming from this change - Will find out bad things about the boards if they exist - We will test the BLE and Wi-Fi functions and measure power consumption - And we will try to answer the essential questions: What are the implications for the future of the Arduino platform. And: Is there a new star born?

We all love our Arduinos and ESPs. But do you know or remember where they came from? Today we start a journey back to the late 1970 and early 1980s where the “Personal Computer” journey began. The chips used back then were simple and gave honest feedback. That is why we can learn a lot about today’s chips. Like Ben Eater "Hello, world” from scratch on a 6502 ", just much faster. Do you want to accompany me on this journey? Today we will start by looking at the different parts and tools used back then. - We will try to find the roots of our microcontroller used in Arduinos - We will use Intel’s 8085 family of chips - We will look at the different parts like CPU, different types of memory, and peripherals - We will work with EPROMS. Which is very “old fashioned” - We will have to understand address and data busses - We will deal with addressing different chips and so design a memory map - We will learn how to de-multiplex addresses from data - During this work we will learn a little about the famous 74xx chip series - In the end, we have a schematic for a simple SBC with 4KByte EPROM, 2kByte RAM, a timer, and 24 IO Pins.

You will also learn how to do that and stay legal. And maybe we even can reduce the power consumption of the chip if we do not need the extended range. And what we learn, we can also be used for our ordinary Wi-Fi network. Unfortunately, it does not work with the ESP8266. I am a proud Patreon of GreatScott!, Electroboom, Electronoobs, and others. This is part 2. Maybe you want to watch part 1 first?

If you ask me which instruments I regularly use in the lab, you will hear Multimeter, Oscilloscope, Transistor or Component Tester. And since quite some time I ask myself: How is it possible to build such a versatile component tester for less than 10 dollars. After looking at the minimal parts count of such a device, I am convinced: The inventor was a Genius. Let’s have a closer look.

What the hell is Zigbee? Do I really need to care about it? It is mainly used by expensive devices like the Philips Hue system for people with deep pockets? This is what I thought until now. But I have indications that this changed. Let’s have a closer look. We all know Wi-Fi, Bluetooth, 433MHz, and LoRa devices and probably already use some of them. So, what is Zigbee? How does it fit into the other technologies, and how can we get a head start with it? Let’s play with the technology and learn how it works and whether and where it can be useful for us. Or if we can skip this one. I am a proud Patreon of GreatScott!, Electroboom, Electronoobs, and others.

It is well known that the Raspberry Pi 4 gets quite hot and reduces its processing speed if it has to work hard. In one of my Quickies, I tested the passive FLIRC case. In the comments, viewers pointed me to two Chinese cooling solutions and Cristopher Bartlett from Explaining computers tested a few others. Time for a new Quickie with a summary of all these coolers. And some ideas for optimizations. I am a proud Patreon of GreatScott!, Electroboom, Electronoobs, and others.

A remotely controlled, precise analog wall clock like that one from IKEA is a cool thing. Today we will build our own remote control for such analog and digital clocks. All we need is a Raspberry Pi and a few electronic components. And we will learn something about resonance frequencies, capacitors, and ferrite antennas. Let’s hack! I am a proud Patreon of GreatScott!, Electroboom, Electronoobs, eevblog and others. You can do the same using an ESP32: https://github.com/aknik/ESP32/tree/master/DFC77 In this video, we will: - Learn how radio-controlled clocks work - We will build a ferrite antenna for receiving and transmitting time signals - We will test and optimize it - We will install software on our Raspberry Pi to create signals for DCF77, WWVB, MSF, and JJY In the end, I should have a precise time in my lab.

The whole world goes wireless. And digital. One technology is right in the center of these two megatrends: Software Defined Radio or short: SDR. Do you know how it works? And how you can take advantage of it? If you do not want to take the time to watch Michael Ossmann's (Great Scott Gadgets) series, then this SDR tutorial is for you Software-defined radio is a relatively new technology and was extremely expensive in the past. Then came this small USB dongle for 10$ and changed all. And other, more capable devices like the HackRF One for 300$ pushed this technology into the mainstream. Today, most modern radios used for example in Smartphones, in Amateur radio equipment, or Satellites are SDR radios. This is the reason for the tutorial. I am a proud Patreon of GreatScott!, Electroboom, Electronoobs, and others. #SDR #Tutorial #Electronics My HAM radio channel: https://www.youtube.com/channel/UCQwyP4Yd0-O49e05kMUJgQQ Links: HackRF one: https://amzn.to/3ei2gQn Clones: http://bit.ly/2ZEe3Df or http://s.click.aliexpress.com/e/MnOHFW5w RTL-SDT V3: http://s.click.aliexpress.com/e/B08cnKey RTL-SDR Dongle: https://s.click.aliexpress.com/e/_9QvOSo (RTL2832U , R820T2 ) Pluto plus (better): https://s.click.aliexpress.com/e/_9G4To5 Original Adalm Pluto: https://www.analog.com/en/design-center/evaluation-hardware-and-software/evaluation-boards-kits/adalm-pluto.html SDR-Play: https://www.sdrplay.com/ Lime SDR: https://www.crowdsupply.com/lime-micro/limesdr Ettus Research: https://www.ettus.com/ SDR Intro by M.

A picture says more than a thousand words. This is why the world is moving away from text to images and videos. We, as Makers, can profit from this movement because we get dirt cheap hardware to play with. And if it works with an ESP32, even better. Time for a closer look. I am a proud Patreon of GreatScott, Electroboom, Electronoobs, and others. In this video I will: - Compare the features of the four boards - Try to get all of them working.

In my last video, I showed a quite complicated way to flash the new Sonoff Mini. In today’s quickie, I show you a more straightforward method to get the job done. Sonoff made it complicated to flash a new Firmware on a Sonoff Mini. In the comments viewer suggested to solder four wires to the four pins on the PCB. This is possible, and it works. But you need some soldering skills. Another viewer discovered a different method on Thingiverse: Print a programming jig and use it to flash the Mini.

In his last video, GreatScott was not successful in building a Walkie Talkie project and suggested that we use his schematic to find out the problem. Because I like his work, and I love all sorts of wireless gadgets, I decided to give it a try. Debugging anyway is an essential skill of a Maker because errors help us to learn. And to make it clear: GreatScott did not make an obvious nor a dumb mistake as he suggested.

Modern cars measure tire pressure and display it on the dashboard. How does this technology work? Can we use it for our projects? And what happens if we try to attack it? Let’s hack TPMS! We all know these pressure sensors from our weather stations. They are very accurate, but only good for 1100 hPa, which is 1.1 bar. What if we want to measure higher pressures? Then we need this kind of sensor. And if we're going to use it in a battery-operated device? Maybe wirelessly coupled to our Raspberry? Then we come to something like that: A ready-made tire pressure sensor. It contains all we need: A sensor, a microprocessor, a transmitter, and a battery. And it costs around 10 dollars. We even get a cheap solar powered display. Cool. But how does it work? And how can we hack it? And finally: What does this all have to do with beer?

Writing Alexa or Google Home skills is not easy, their voices are impersonal, and we never know what they gossip elsewhere. Also, the devices are not funny looking. We will build a system which, when triggered by MQTT, plays voice messages. It uses a JQ6500 sound module which can play mp3 files. A PAM8304 and an ESP8266 (also an ESP32 would be good) is also part of the design.

Viewers often ask me how I print cases for my projects. In this video I will show you how you can print your own boxes with a simple and free of charge method based on what I call a “Configurable Base Box.” As usual, we will focus on how you can get the things done. It will not at all be a CAD tool training video. In this video we will: - Find the information to install Fusion360 and get a free of charge license for Makers - Use my adjustable “base box” as a head-start - Adjust this box to the right size and add some holes for power, LEDs, or other stuff - I will also show you a trick on how I create perfect 3D printed holes - and how I attach PCBs like an Arduino inside the box Links: Free Maker license for fusion360: https://www.autodesk.com/campaigns/fusion-360-for-hobbyists File with box template: https://github.com/SensorsIot/Project-Box-Templates Adafruit video: https://www.youtube.com/watch?v=VVmOtM60VWw Prying Tool: http://s.click.aliexpress.com/e/8K0Pt6s Reamer: http://s.click.aliexpress.com/e/6YHZel6 or http://bit.ly/2HMfhzT Step-Drill: http://s.click.aliexpress.com/e/bDtwC7Vm or http://bit.ly/2GRYxK7 or https://amzn.to/2EiSAlE Arduino Mega: http://s.click.aliexpress.com/e/b2BFQmZ6 Supporting Material and Blog Page: http://www.sensorsiot.org Github: https://www.github.com/sensorsiot My Patreon Page: https://www.patreon.com/AndreasSpiess Alternative: https://flattr.com/@andreasspiess My Bitcoin address: 19FSmqbBzb5zsYB1d8Bq4KbxVmezToDNTV If you want to support the channel, please use the links below to start your shopping.

Are Li-Po or Li-ion batteries really useless or even dangerous in low temperatures? Selecting the right battery for our project (Arduino, ESP32, or ESP8266) is very important. Today we will focus on which battery works best in low temperatures. We will test: - Several battery technologies, rechargeable, and non-rechargeable - We will compare their behavior at room temperature and at -18 degrees C - We will check the discharge behavior of all batteries - We will try to charge the rechargeable batteries at -18 degrees - We will use small currents, similar to a typical solar-powered Arduino or ESP project - In the end, we will know if anything exploded during the tests Links: Li-Ion: http://s.click.aliexpress.com/e/XFq5Vve Li-Ion: http://s.click.aliexpress.com/e/gPLLmIy Li-Ion: https://amzn.to/2TOFqmU Li-Po: http://s.click.aliexpress.com/e/G0FM6wy Small Lead-Acid: http://s.click.aliexpress.com/e/bs3efzoU Big Lead Acid: http://s.click.aliexpress.com/e/byp9Z8QU LiFePo4: http://s.click.aliexpress.com/e/ccq9MiqG Lithium-Thionyl-Chloride : http://s.click.aliexpress.com/e/cgMMByAU Charger: http://s.click.aliexpress.com/e/bWK2V3Li Overview battery technologies: https://batteryuniversity.com/learn/article/secondary_batteries Supporting Material and Blog Page: http://www.sensorsiot.org Github: https://www.github.com/sensorsiot My Patreon Page: https://www.patreon.com/AndreasSpiess Alternative: https://flattr.com/@andreasspiess My Bitcoin address: 19FSmqbBzb5zsYB1d8Bq4KbxVmezToDNTV If you want to support the channel, please use the links below to start your shopping.

We can save energy by deep-sleeping the ESP32. During this time, the chips do not consume a lot of energy but also are not responsive. This is why Espressif included a mysterious Ultra Low Power core (ULP) which is active when the main processor sleeps. People say it has to be programmed in Assembler, and nearly nobody was able to program it in the Arduino environment. Until now.

Uninterruptable power sources or UPS for your Raspberry Pi, Arduino, or ESP microcontroller usually are quite expensive and also do not always work. When I found these small 2 dollar modules, I asked myself: Can we use them as a UPS? Or are they just junk and false promises? Time for a closer look! From time to time viewers ask how they should power their projects, especially with batteries. Today we will take a look at this small module and find out if it is any good, how it compares with Power Banks, and where it fits in the “energy supply chain.” Links: UPS:http://s.click.aliexpress.com/e/ccgnehR2 or http://bit.ly/2RbEP1h USB Tester: http://s.click.aliexpress.com/e/by2eDXAo or http://bit.ly/2FNp1ch Good Li-Po Batteries: http://s.click.aliexpress.com/e/c5KnNc8C Additional info: https://youtu.be/T70mBHeIOZA Supporting Material and Blog Page: http://www.sensorsiot.org Github: https://www.github.com/sensorsiot My Patreon Page: https://www.patreon.com/AndreasSpiess If you want to support the channel, please use the links below to start your shopping.

This is a different video. The technical level is low, the fun for the builder high. And, as usual, it contains a microprocessor and a sensor. I wish you a Happy 2019 Link: Wow stick: http://bit.ly/2BMUM3p or http://s.click.aliexpress.com/e/crmLlcM0

Is this a cool thing? A self-made thermal imaging camera! For only a few bucks! Sounds marvelous. Because recently lower cost sensors appeared on the market this seems to be possible. Today we will see where we can use them and if they are worth the money. We will compare the following sensors: - We will start with the ordinary PIR sensor with 1 pixel - And continue with the AMG8833 which has 8x8 pixels - The next is the MLX90640 with 32x24 pixels - And the last is a Flir One 160x120 pixels camera which has to be mounted on a smartphone And we will use an M5Stack to build a camera using Arduino IDE Links: Hackaday Ardicla: https://hackaday.com/2018/06/08/who-said-thermal-cameras-werent-accessible-to-the-masses/ AMG8833 and MLX90640 Sensors: http://s.click.aliexpress.com/e/bY96Z8Gg M5Stack: http://s.click.aliexpress.com/e/z7rgAUg Sketch: https://github.com/SensorsIot/Thermal-Imaging-Camera-MLX90640 Flir one pro: https://amzn.to/2EJ1njh Flir one: https://amzn.to/2QOO3AJ Supporting Material and Blog Page: http://www.sensorsiot.org Github: https://www.github.com/sensorsiot My Patreon Page: https://www.patreon.com/AndreasSpiess My Bitcoin address: 19FSmqbBzb5zsYB1d8Bq4KbxVmezToDNTV If you want to support the channel, please use the links below to start your shopping.

During Deep Sleep, microcontrollers consume very low currents, and batteries live longer. Unfortunately is not easy to measure these small currents. Today we will check out two small boxes which promise to make this possible. And we will use the 10’000$ professional Keysight N6705C Power Analyzer to establish the reference. The first contender is the well known µCurrent Gold which is made by Dave Jones from EEVblog. It is the “mother” of this device category and costs around 80$. The other is called Current Ranger and is built by Felix Rusu from Low Power Lab. It just entered the market and is an extension of Dave’s concept and costs around 120$. And we will use an ESP32 to check it out.

QC3.0 is the new standard for charger used by many companies, and therefore we get lots of compatible power banks and wall chargers. They deliver up to 12 volts and later up to 20 volts. And the voltage can be adjusted. Sounds like ideal for a Lab or a Mobile power supply. But unfortunately, the standard is proprietary. So let’s hack it using an Arduino Mini or an ATtiny. The old USB chargers were able to deliver 5 volts and around 2-amperes max. The new QC quick charger chargers provide up to 12 volts and 2A peak. And you can change the voltage on the fly. Sounds interesting and dangerous! I do not want to charge my trusted old iPhone with 12 volts. I assume this would not be accepted as a warranty case by Apple… Links: Vince's blog: http://bit.ly/2Pf9DbM QC 3.0 charger: http://bit.ly/2KKFdh3 QC 3.0 Power Bank: http://bit.ly/2JSwysr QC tester: http://s.click.aliexpress.com/e/cqPyt9ZW QC3 library: https://github.com/vdeconinck/QC3Control Supporting Material and Blog Page: http://www.sensorsiot.org Github: https://www.github.com/sensorsiot My Patreon Page: https://www.patreon.com/AndreasSpiess My Bitcoin address: 19FSmqbBzb5zsYB1d8Bq4KbxVmezToDNTV If you want to support the channel, please use the links below to start your shopping.

Several technologies exist to connect electronic components.

433 MHz devices are used everywhere because they are cheap and easy to use. In this video, I will build an affordable gateway which transfers 433MHz messages via Wi-Fi to out MQTT broker. The device uses RFLink firmware on an Arduino Mega and an old ESP8266 (ESP-01) module. Then I connect my new Chinese Weather Station to this gateway and, through some Node-Red porn, get the data neatly on a browser screen. It also can be used to steer all sorts of other devices.

Most of our IOT devices are insecure and vulnerable. It’s high time to learn how to make them more secure, also because unsecured devices will no more be able to use valuable services without using the HTTPS protocol. Already now, Google services, for example, do no more accept unsecured connections. But is it complicated? Let’s find out! Our ESP8266 and ESP32s support such secure connections. In this video, I will show you, how to change your unsecured sketches it in a few simple steps. And you will learn some basics about encryption and certificates.

As you know, microcontroller boards have many pins, and wiring them to other components or keeping track of the different wires sometimes is not easy. Today I show you how I do it. Most of the tricks work for all microprocessor boards like the Arduino, the ESP8266 or the ESP32. And with a unique feature of the ESP32, we can optimize a little more. In this video, we will cover the following tips and tricks: 1. Use colors 2. Connect ground first 3. Pre-fabricated wires 4. Use empty Dupont shells 5. Use the right pin order 6. Not enough Ground or VCC connections on our development boards 7. Super Glue can help sometimes 8.

You want the functionality of WiFi manager, secure over the air update, and an overview over all your ESP devices wherever they are? Two years ago, we announced IOTappstory as a Christmas gift. It was the first Appstore for IOT devices, and it worked for the ESP8266. Today we can announce that it also works with the ESP32. And it got much cooler. The idea behind IOTappstory.com is to make it simple and secure to distribute and manage software for IOT devices over the air. Most of us implemented some connected devices in our homes. At places, we cannot easily upload new software or change parameters like passwords or access keys. And if we have more and more of those devices, we even might lose control of which software runs on which board. The new IOTappStory.com developed by Onno and me over the last two years - consists of a library and a Webservice - stores and distributes software, SPIFFS files, and parameters for ESP8266 and ESP32 boards - the distribution is done over the air (OTA) - it has all the functions of WiFiManager like entering Wi-Fi passwords or settings - it uses HTTPS for transport and makes sure only you can upload software to your devices - You can monitor your devices over the network - It works globally. You can also manage your devices in a remote location - The footprint on your ESP is optimized because most of the functionality runs in your browser Today I walk you through the installation and the startup of an ESP32 using IOTappStory.com.

Keeping promises is very important. So let’s check if the suppliers of our newer LoRa boards keep their promises. The first ESP32 boards were disappointing as I showed in video #182. In today’s contest are: - TTGO LoRa32 board Version 2.0 - TTGO LoRa32 board Version 2.1 - TTGO LoRa32 T-beam board - LoRa32u4 II I will measure the maximal output power and assume, that the receiving channel behaves similarly to the transmitting circuit.

Today we will start to understand how RFID cards work and how they can be used with your Arduino. You will see, which cards and readers are available and how they compare, we read RFID cards from a hotel and a trade show, and we will do some experiments to protect your cards against attacks. And maybe we even clone cards? All legal, or at least, sort of.

Sometimes we need more memory for our sketches. In this quickie, I show you how you get it without heating up your soldering iron. Most of the ESP32 modules have 4Mbyte flash memory chips. But if you look at the usable memory size, you only get 1310720 bytes, which is roughly one-quarter of your flash memory. With a blink sketch, this is no problem. It only uses 13% of the available space. But if you use the simple BLE_server example, which is just a few lines long, it occupies already 85% of your flash memory. If you add some other libraries, you quickly get an “out of memory” error. Partitioning and ESP32 partition tables provide the solution.

I should have been warned: Some viewers on our summer project were against a gun on the tank. But I did not listen. This video shows what happened and how I was punished. In Switzerland, every adult man is in the army and has his weapon at home. Maybe this is the physiological reason for my choice. I am no psychologist; I am an engineer.

In part one of this video, we started to answer the nine most important questions about wireless communications for Arduino Makers. In this video, we will continue and dig more into the matter. If you did not already watch the first part, I strongly suggest clicking on the link in the upper right edge of your display now. Grüezi YouTubers. Here is the guy with the Swiss accent. With a new episode and fresh ideas around sensors and microcontrollers. In the first part, we talked a lot about the influence of carrier frequency and started to understand the concept of bandwidth. In this video, we will cover - The significance of bandwidth on wireless communication - The different modulation principles - Methods to increase the reliability of wireless connections - And we will learn which methods were preferred by spies And we will use all our knowledge to compare two well-known wireless modules, the NRF24L01, and the RFM69. Both representing very different concepts Links: Part 1: https://youtu.be/ILhXHO5vIxc NRF24L01+: http://s.click.aliexpress.com/e/bHFXGCkC or http://bit.ly/2Ngxwzx NRF24L01 Long Range: http://s.click.aliexpress.com/e/EelCKjA or http://bit.ly/2NgExQN RFM69HCW: http://s.click.aliexpress.com/e/cfm7Bn1m (Always use high power version, you can reduce power if needed) Supporting Material and Blog Page: http://www.sensorsiot.org Github: https://www.github.com/sensorsiot My Patreon Page: https://www.patreon.com/AndreasSpiess My Bitcoin address: 19FSmqbBzb5zsYB1d8Bq4KbxVmezToDNTV If you want to support the channel, please use the links below to start your shopping.

At the end of the two videos, you will understand everything necessary about frequency, modulation, bandwidth, power, propagation and a few other aspects to take the right decision for your project. And you will learn at least two new words: Time and frequency domain. Questions answered: - Which module should I use? - What is the operating range? - What is the throughput? - What is the connection reliability? - Can it communicate one- or two way? - How much energy is needed for the transmission? - Which module is better? - What is legal? - What about security issues?

Rubber duck debugging is a famous way to solve problems. Today we will combine this technique with Socratic questions and swarm intelligence, two other powerful methods. The goal is nothing less than to create the best problem solver in the internet age. One which was never built before. And our budget? Below 10 $. Because we can use an ESP8266 and free Google Sheets.

Hacking of 433 MHz or other RF devices is a human right for makers because these devices usually use proprietary protocols. Today we will reverse-engineer a so-called “professional” weather station from China and enable it to send its data via MQTT. Then we will hack the remote control of our outdoor awning and use an ESP32 to build a fake twin which understands MQTT. We will use a Raspberry Pi and Software Defined Radio (SDR). You will be astonished how professional this will get.

Summertime is fun time. This is why I will start a new project, an autonomous Robo Tank. It should be fun, but also contain new things I never did so far.

Blue light in the evening can create problems for your sleep. Especially very white LED lights around us produce lots of it and prevent us from falling asleep after a hard days work. Let’s build a “Sleep accelerator” device using an ESP8266, an IR LED, and a MOSFET. It reads actual sunrise and sunset times as well as the time and synchronizes the color of your LED with the sun.

Laser range sensors can measure long distances with high precision. Today we try to build not only such a range sensor. We want to use it also as laser speed gun. Will it better than our radar sensor? In video #181 we tried to measure speed using a cheap radar sensor. This project is still in the lab, and I expect an update in the next month or so. In the meantime, I started experimenting with another technology we already encountered in video #119: Time of Flight sensors used in LIDAR systems. This was one of my longtime wishes, and it became reachable when I saw these new rangefinder modules pop up on AliExpress. They have no display but a digital interface. Exactly what we need for our hack.

Multimeters are suitable for many purposes. But usually, they only measure one value at a time. If we deal with power or capacity measurements, we need two multimeters, one for volt and the second one for ampere. And if we want to measure efficiency, we need four multimeters. In earlier videos, I used small all-in-one meters for that purpose and got the request to show how I built them. So today we will build small and cheap meters which measure volt, ampere, power and capacity at the same time. For around 15 dollars each.

Multi-Channel Lora Gateways are quite expensive, and competition amongst the suppliers was not significant. This is why I was happy when RAK Wireless announced its RAK831 concentrator board. And also my viewers. They voted for this video. Today we will build a LoRaWAN gateway which costs less than half of the first one I made one and a half years ago. With today's project, we will build a gateway using this concentrator and a Raspberry Pi zero.

These days they tell us that they will close down our FM radio stations here in Switzerland. Time to start a new venture: Digitalize our radios without spending too much money. I already some time ago, started this venture with an ESP8266 but was not successful. I still have a box with a label “ESP radio” on my shelf.

Today we will hack an IKEA SALTVIKEN bathroom scale and create a connected weight sensor for up to 150 kg. We will use Googles free No- SQL Firebase cloud service as a data storage. To do that, we have to tear this nice scale apart and have a look inside. We will: - Re-use the load cells of the IKEA scale to measure heavy loads up to 150 kg or another scale, maybe even old an defective one - Replace the original PCB with an HX711 and an ESP32 (should also work on ESP8266) - Learn from IKEA how to wire the four special load cells that they add the weight - Transfer data to the new No-SQL database “Firebase” provided by Google - Calibrate the scale Links: Sketch and connections: https://github.com/SensorsIot/Weight-Sensors Firebase Library: https://github.com/ioxhop/IOXhop_FirebaseESP32 How to wire 3 wire Load Cells: http://bit.ly/2HjtPXM Conventional Load cell: http://bit.ly/2GFqt04 HX711: http://bit.ly/2EtefWc http://s.click.aliexpress.com/e/ufeQB27 Load cell 50kg: http://s.click.aliexpress.com/e/u33zBIa Load cells 5kg: http://bit.ly/2IAMfm3 For longtime use, these cells seem to be not ideal.

This is a Quickie. The handling of SMD parts is much simpler than the one of through-hole components. And it is much faster. Together with the cheap PCB services offered, every maker can produce professional devices at very low cost. One thing, however, remains a problem for some people: Soldering these small components. Today I show you how we simplify it with a cheap Aldi oven and nothing else. No controller needed.

Today we will look at different new ultrasonic sensors and compare them: US42V2, JSN-SR04T, and US-100. As usual, this should help you decide if you need distance sensing in one of your next projects. In mailbag videos # 186 and 187 I asked you which parts I should use first for a video. The verdict was clear: The RAK831 LoRa gateway and the Ultrasonic distance sensor. This is not my first video about these sensors: You find an introduction and test in video #40 and a three-way sensor using an ATtiny and a home-made I2C interface to connect to the MPU in video #42. If you are interested in the basics, maybe you want to watch them first. There I used the commonly available and cheap HC-SR04, HY-SRF05, US-015.

Everything goes wireless these days. This is why we have a close look at the “black magic” of antennas, how they work, what is essential, and how to test them. Based on this knowledge we will build a cheap antenna tester for LoRa antennas. A similar device can be built to test Wi-Fi antennas. It uses an ESP32 TTGO board on one side and a Wemos D1 mini with a Hope RFM95 module on the other side.

Forgetting your duties is not good. Forgetting things which are asked by your wife or your girlfriend is even worse. Today we will solve this issue and make our women happy. And, as my grandfather said: Happy woman, happy man. Many tasks are recurring or can be planned. Most of us use calendars for that. These calendars also offer notifications which pop up on the Smartphone. Good, if you do this task in the next minute. If not, the chance it gets forgotten is significant, primarily if I am working on an exciting project. This is why I desperately need the small device we will build today. Its momentary name is “Reminder Device”. It stores all notifications until they are confirmed. And because it is cheap and small, we can place several of them where the action has to take place. What are the required features of such a “reminder device”? - Remind me as long as I did not confirm “Job done” - Get the tasks from Google Calendar - If confirmed “job done,” the same job must not reappear - Single and multi-task versions - Powered by a USB charger - Arduino IDE UPDATE VIDEO: https://youtu.be/ZFgh2KFLeGA Links: Google Calendar Library: https://github.com/wilda17 Sketch: https://github.com/SensorsIot/Reminder-with-Google-Calender LED buttons: http://s.click.aliexpress.com/e/NbUjYV7 Wemos D1 mini: http://bit.ly/2oXSx5X Boxes (stl files): https://www.thingiverse.com/thing:2806384 Supporting Material and Blog Page: http://www.sensorsiot.org Github: https://www.github.com/sensorsiot My Patreon Page: https://www.patreon.com/AndreasSpiess If you want to support the channel, please use the links below to start your shopping.

I often get requests for help because something does not work. This seems to be the most common problem for makers. After this episode, it should be easier and faster for you to find issues or problems. Only if you find the root cause you can make your devices run correctly. Otherwise, the defect will return. And if it takes too long to find an error, it is boring. Links Problem with Radar: https://github.com/jdesbonnet/RCWL-0516/issues/2 The rules: 1. Ask if it already worked once. Maybe also somewhere else 2. Separate components to reduce complexity 3. Exchange components 4. Always buy two or more parts if they are affordable 5. Reduce the number of possible interactions 6. Only continue if all components tested so far work 7.

Most of our modern processors and sensors need a stable power supply of 3.3 volts. Some older chips require 5 volts. And a raspberry pi needs nearly 1 ampere while an ESP in deep sleep requires only a few microamperes. Sometimes the current consumption is quite stable, and sometimes we have big current spikes like our ESP chips during Wi-Fi transfers. - We will discuss the two different principles for control of voltage: Linear and switching (buck, boost) regulators - We will find out why linear regulators efficiency often is bad and where this fact is not significant. We also look at the thermal design and how it influences maximum current - We try to understand why switching regulators have higher efficiencies and can be built smaller for high currents or higher differences between input- and output voltage - We look at the output ripple and on other high-frequency signals and where they can hurt - We will test how the different regulators behave when your processor is in deep sleep - Finally, you should be able to make the right decision for your project -And you should be able to do a small talk using all the buzzwords mentioned before ERROR CORRECTION: Low Quiescent Regulator is HT7333, not HT7111.

Is ESP32 BLE really power efficient? How does it compare with Wi-Fi? And with a dedicated BLE beacon? Power is a precious good in battery powered devices. Today we will investigate how much power a ESP32 burns in normal mode, using Wi-Fi or Bluetooth, in deep-sleep, and in mixed scenarios where it sleeps and sends data every few seconds.

In summer 2015 I decided to change from a passive YouTube viewer to the role of an active YouTube creator. Since then I learned a lot. Some things I believe are interesting for you if you think about starting your channel, but most of it is also interesting, maybe even important for viewers. This is why I would like to let you see behind the scenes and discuss the vital question: Why to become a YouTube creator and why to continue to be one? The answering of this question should also lead to understanding some of the changes on this channel for 2018. It is nine months since my last update in April. Back then this channel had around 20’000 subscribers. Today, it has more than 50’000. I take this fact as feedback that many of you like the content it provides.

Are my USB cables any good? Or will they vaporize if used? I will answer this questions for my cables and you will learn how to test yours (tutorial) to avoid surprises in the future. We use USB cables for many of our projects and other devices like smartphones. Sometimes our projects do not work, and we are not sure if a crappy USB cable is a reason. When I recently showed a batch of USB cables in my mailbag video, a viewer wrote, that they are not of good quality. This is why I will have a closer look at my USB cables.

Presence detectors/Sensors are essential for today’s home automation systems In earlier videos we looked at PIR and radar sensors, and we were even able to use Wi-Fi on our smartphones to sense our presence. All have advantages and disadvantages. Today, we create the ultimate presence detector. And the best: It costs only a few dollars. How does this ultimate presence sensor work? Of course, with Bluetooth low energy and an ESP32. - In this tutorial we will build a valuable BLE application which can solve a real problem - We will learn how BLE advertising in detail works - We will trace BLE packets to the last bit.

Good news! My fake Polar H7 Bluetooth heart Rate sensor works on my ESP32 using the Arduino IDE. I will show you what I had to do. And much more! Today I can show you - How you can build a sensor which sends data via BLE to a client - A client which can receive these values and display them in Serial Monitor - The mysterious BLE2902 client characteristic configuration and how it works - The details of the protocol used by the heart rate measurement characteristics. This will help you to build other sensors based on different standardized services and characteristics Links: First tutorial video about BLE: https://youtu.be/2mePPqiocUE Sketches: https://github.com/SensorsIot/Bluetooth-BLE-on-Arduino-IDE Neil Kolban's Github: https://github.com/nkolban ESP32 board used: http://bit.ly/2sOMR3E Supporting Material and Blog Page: http://www.sensorsiot.org Github: https://www.github.com/sensorsiot My Patreon Page: https://www.patreon.com/AndreasSpiess If you want to support the channel and buy from Banggood use this link to start your shopping: https://bit.ly/2jAQEf4 (no additional charges for you) https://www.facebook.com/profile.php?id=100013947273409 https://twitter.com/spiessa https://www.instructables.com/member/Andreas%20Spiess/ Please do not try to Email me or invite me on LinkedIn.

So far, we had to use Espressif’s tools to use Bluetooth on the ESP32. Today I will try it with the Arduino IDE. I am curious how it will work. Maybe you come with me on this discovery tour? For sure, we will learn a lot about how Bluetooth low energy, or BLE, works. In this video we will cover: - The basics of Bluetooth Low energy - The different roles of devices - How we debug BLE connections using our Smartphone - We will build a notifier and a client - We will try to fake a Polar H7 Heart Rate monitor (at least, the BLE part - If we have time, we will have a look at An iTag Chain finder and a Xiaomi Flower care system - And maybe we will discover some “secret sauces” necessary for a delicious meal?

Today we will discover a hidden feature to connect two or more ESP32s or ESP8266s directly to each other: ESP-now. It is much faster and more energy efficient. And we will compare it to LoRa (RFM95 and Arduino Pro Mini. Espressif gave us this possibility and, because it is so fast, they called it ESPnow. And it also works in the Arduino IDE. In this video, we will - Try to understand the difference between the standard ESP mode and ESPnow - Build a working ESPnow connection for two ESP8266 - Check-out the transmission speed and - Compare this speed with the speed if we connect the ESP to the internet - Compare the Energy hunger of both modes - And finally, compare the ESPs with another technology: LoRa Links: Sketches: https://github.com/SensorsIot/ESP-Now-Tests ESP-Now example: https://github.com/HarringayMakerSpace/ESP-Now Not-rebooting gateway: https://github.com/HarringayMakerSpace/IoT/blob/master/ESP-Now/espnow-gateway/espnow-gateway.ino Online Battery life calculator: http://battery-life.of-things.de/battery-life-calculator.php ESP32 board: http://bit.ly/2sOMR3E Supporting Material and Blog Page: http://www.sensorsiot.org Github: https://www.github.com/sensorsiot If you want to support the channel and buy from Banggood use this link to start your shopping: https://bit.ly/2jAQEf4 (no additional charges for you) Official Wemos Store: http://s.click.aliexpress.com/e/jUzBiIq https://www.facebook.com/profile.php?id=100013947273409 https://twitter.com/spiessa https://www.instructables.com/member/Andreas%20Spiess/ Please do not try to Email me or invite me on LinkedIn.

Everybody talks about Bluetooth and Wi-Fi. But one heavily used technology is often forgotten: Infrared. Today we will remember this technology and bring it into the today's world of microcontrollers like ESP32 and ESP8266 and to technologies like MQTT and node-red. And as usual, we will dig a little into the basics. Today - We will use infrared rays to detect objects - And find a way to make the detector immune against interference from daylight - We will use standard photodiodes as well as IR receivers to detect IR signals and see the difference - Then we will use IR instead of LoRa or Wi-Fi to transport information over the air - We will enable an Arduino UNO to receive, learn, and send IR codes - We will port the IR library to the ESP32 and implement MQTT - Finally, we will build a device which can control our home appliances like TVs or Lights - This device should be able to receive signals from an IR remote controller and transfer them via MQTT to Node-Red Links: Sketches: https://github.com/SensorsIot/Definitive-Guide-to-IR Video about Phototransistors & -diodes: https://www.youtube.com/watch?v=DNAgJrnj4EM IR code databases: http://irdb.tk/ , https://github.com/probonopd/irdb IR Receivers: http://s.click.aliexpress.com/e/3vnAUB6 IR Sensor: http://bit.ly/2BdXEEJ IR LED & Photodiodes: http://bit.ly/2BcRd4G IR LED & Photodiodes: http://s.click.aliexpress.com/e/rNnmIyZ Reflective IR sensors: http://s.click.aliexpress.com/e/iYNBaUn ESP32: http://bit.ly/2sOMR3E Arduino UNO Clone: http://bit.ly/2tJE9Af Interesting ESP8266 IR/MQTT project: https://github.com/enc-X/mqtt-ir-transceiver Supporting Material and Blog Page: http://www.sensorsiot.org Github: https://www.github.com/sensorsiot If you want to support the channel and buy from Banggood use this link to start your shopping: https://bit.ly/2jAQEf4 (no additional charges for you) Official Wemos Store: http://s.click.aliexpress.com/e/jUzBiIq https://www.facebook.com/profile.php?id=100013947273409 https://twitter.com/spiessa https://www.instructables.com/member/Andreas%20Spiess/ Please do not try to Email me or invite me on LinkedIn.

Nextion HMI displays are great. But the documentation and the support is not very good, and the library currently does not work with the ESP32. Today I will show you the five most important features of the enhanced version and how to use them. In the end, you will have a small keypad which can be used as a control center for your home automation. And of course, the library works now with the ESP32, not only with the Arduino. I did already some videos about Nextion displays. They are the basis for this video and worthwhile to watch because I will not cover these details again. You will find links in the description. Today we will: 1. Build a small device using a Nextion display with 6 Softkeys 2. When one of these keys is pressed, the beeper on the extension board will beep. You will learn how to achieve this by programming the display itself 3. Each key triggers an MQTT message. This message can be used to switch devices in your home-automation system 4. The device can receive MQTT commands and switch a relay accordingly 5. The enhanced version has a Realtime clock aboard. We will synchronize this clock once using internet NTP time. From then on, the display updates the time itself Links: My Nextion videos: https://www.youtube.com/playlist?list=PL3XBzmAj53RlXES3erPR4F0Zk08Hx1YdA Code: https://github.com/SensorsIot/Nextion-Enhanced Another library: https://github.com/darrenjcosborne/NextionSerialString Enahced Nextion displays: Different sizes: http://s.click.aliexpress.com/e/bBVLEfQ0 3.5" Enhanced Nextion Banggood: http://bit.ly/2zSlqGI 7.0" Enhanced Nextion: http://bit.ly/2zQPfHY ESP32 Board: http://bit.ly/2sOMR3E Supporting Material and Blog Page: http://www.sensorsiot.org Github: https://www.github.com/sensorsiot If you want to support the channel and buy from Banggood use this link to start your shopping: https://bit.ly/2jAQEf4 (no additional charges for you) Official Wemos Store: http://s.click.aliexpress.com/e/jUzBiIq https://www.facebook.com/profile.php?id=100013947273409 https://twitter.com/spiessa https://www.instructables.com/member/Andreas%20Spiess/ Please do not try to Email me or invite me on LinkedIn.

You might have heard about LoRaWAN, a network of connected nodes with gateways, brokers and more. If this is too complicated for you, you do not have an internet connection, or if you do not want to depend on other’s infrastructure this video is for you: Today, we will build a point-to-point connection using two plain LoRa modules. And of course we will check out the range of this connection. In the end, I will know when the postman put the nice packets from China into my mailbox. Without going into the freezing winter weather. Today - We will build two lovely LoRa nodes, one with an Arduino and one with an ESP8266 - The Arduino LoRa node will be the sender of sensor data - The Wemos node will act as a receiver of the data. - It will also get an MQTT connection to node-red - We will take some precautions against lousy communication conditions and implement a feedback mechanism - We will do some range testing of this LoRa connection - We will learn about reducing the power consumption of Arduino boards using the sleep mode - I will use “precompiler directives” to ease a programmer’s life - At the end, you will also know what LoRa has to do with drones If you want to support this channel at your 11.11.

The new ESP32 has three cores. Two of them are very fast; the third is ultra-low power. The Arduino IDE typically only uses one of the fast cores. Today: - We will take full advantage of the second core of the ESP32 - We will test if it really increases the capacity of our microprocessor - We will also compare its dual-core speed with the speed of an Arduino UNO - We will try to synchronize tasks, even if they run on two different cores - We will also try to use the same data on both cores - These two mechanisms are mandatory if you want to use the two cores in a productive fashion - And we will not leave the Arduino IDE.

It is quite clear that SD cards do not live forever, especially not in database or logging applications. Today we will try to solve this issue without spending a lot of money. And maybe we even will gain some speed. Recycling of old hard disks is the name of the game. Will we succeed and what is the speed of these old disks on our Raspberry Pi 3? This video answers the following questions: - What do you have to do to boot your Raspberry from a hard disk instead of an SD card? - Which hard disks are usable for this purpose? - Which interface cables are needed for which hard disk types? - How do these disks perform? We will test - A 2.5” Hitachi mechanical disk. Age: 8 years - A 2.5” OCZ SSD. Age 4 years - A Western Digital 3.5” mechanical disk. Age: 10 years - A KingDian 1.8” SSD. Age: New ADDITION: If you add this line to config.txt: "using max_usb_current=1" the OCZ SSD and even the small mechanical disks boot also with the simple cable and no additional power supply. I did not do long tests if the Raspi power supply likes this... And I had no other things connected to the USB connectors. ERROR CORRECTION: The big WD disk is 3.5", not 5.25" !!!

We will build a sensor which - Monitors its environment and detect all smartphones with enabled Wi-Fi functionality. This is possible because all Smartphones regularly send messages to detect networks around them - Uses the signal strength to detect how far away this smartphone is - Adds all newly detected smartphones to an internal database - Regularly connects to an MQTT server and sends the list of the detected devices to our home-automation or alarm system Theoretically it should be able to detect our presenceas well as the appearance of undesirable intruders. Let’s start to find out if this is possible. And we will learn a few interesting things about privacy in the age of Smartphones.

When I showed you our Atomic Shelter in video #151, I thought, the cold war is over and these shelters are a thing of the past. Just a few days later I had to learn that this is not true anymore. Is it necessary again that we own our own Geiger counter to alarm us if radioactivity is in the air? If you think yes, it is necessary, you will find how you can build one for about 50 dollars In tis video we will: - Build a Geiger Counter with long-term monitoring capabilities using Thingspeak - Make it send alarms to our Smartphone using IFTTT notifications - Understand how it works (incl diagram) Links: Geiger Counter: http://bit.ly/2v3LVH8 or http://s.click.aliexpress.com/e/q37mIMR or https://amzn.to/3qtksfm ESP32: http://bit.ly/2tosirM Nylon spacers: http://bit.ly/2fOJe58 Sketch and diagram: https://github.com/SensorsIot/Geiger-Counter-RadiationD-v1.1-CAJOE- Publication about accuracy: https://www.davidpublisher.org/Public/uploads/Contribute/59362348f32fd.pdf What is fall-out: http://undergroundbombshelter.com/radiation-fallout.htm Counter Board: RadiationD-v1.1 (CAJOE) This episode is based on this work: https://github.com/mkheck/ArduinoGeigerCounter Supporting Material and Blog Page: http://www.sensorsiot.org Github: https://www.github.com/sensorsiot If you want to support the channel and buy from Banggood use this link to start your shopping: https://bit.ly/2jAQEf4 (no additional charges for you) Official Wemos Store: http://s.click.aliexpress.com/e/jUzBiIq https://www.facebook.com/SensorsIOT/ https://twitter.com/spiessa https://www.instructables.com/member/Andreas%20Spiess/ Please do not try to Email me or invite me on LinkedIn.

Let’s build a connected scale, which alarms us when the food bin is empty. Of course, we will be able to use the same principle to measure the weight of any other good like the honey in remote beehives, or even your own weight to visualize it somewhere in the cloud… So, today we will: - Measure quite small weights with an Arduino like Microcontroller - We will need some tricks to do that - Then, we will build a bowl for our cat which is capable to detect if no food is available anymore - And we will send a Twitter alarm to our Smartphone We will also slow down the clock rate of the ESP32 to fit the timing of the HX711chip, and will use an OLED display and an MQTT library.

We often have a few ESP8266 implemented around or lab or homes, inaccessible and in nice boxes. This is why we love Over-the-Air or OTA updates of its firmware. Already a year ago, I came up with the idea of an Appstore for these devices to make OTA easy and to support software distribution for this small devices. Today, we announce the next step: The official Arduino Library. In this video, I will show you: - How to download a prebuilt ESP8266 App to your device without any programming - How to change this App on the fly without touching your ESP - How to write your own sketch or how to enable one of your existing sketches for IOTappStory - And how to manage many deployed ESP8266 devices without hassle Please use at least version 1.0.5 of the Arduino library Wemos D1 Mini https://goo.gl/ZTp7vV OLED Sheild https://goo.gl/PFqh26 Button Sheild https://goo.gl/VzroNp Wemos Dual Base https://goo.gl/MBncPD Battery Shield https://goo.gl/YkLxCp DHT11 Sheild https://goo.gl/QtTrDg Lolin board https://goo.gl/z1tjdc Lolin base https://goo.gl/EwHDx4 IOTappstory is a hobby project.

In this video, we look into the deep-sleep functionality if the ESP32, and we are interested if and how the deep sleep works, especially because the ESP32 has a so-called ultra-low power coprocessor. This fact promises new possibilities. - We will deep-sleep the ESP32 to save lots of power for our battery-operated devices - We will use three out of four sources for wake-up: o The timer o Two possibilities of external wake-ups o Touch pads - We have a look at the available (and sometimes strangely named) ESP-32 pins of the WROOM-32 module - We use RTC memory which survives deep-sleep - And we calculate, how long the ESP32 can deep-sleep compared to the ESP8266 Links: Sketches: https://github.com/SensorsIot/ESP32-Deep-Sleep Excel sheet: https://github.com/SensorsIot/ESP32-Deep-Sleep/blob/master/ESP32.xlsx Instructables: https://www.instructables.com/id/ESP32-Deep-Sleep/ ESP32 Deep-Sleep Details: http://esp-idf.readthedocs.io/en/latest/api-reference/system/deep_sleep.html https://media.readthedocs.org/pdf/esp-idf-fork/latest/esp-idf-fork.pdf https://github.com/espressif/esp-idf/blob/master/docs/api-reference/system/deep_sleep.rst Other ESP32 boards (from video #143): TTGO ESP32 Module https://www.aliexpress.com/item/TTGO-ESP32-Dev-Module-WiFi-Bluetooth-4MB-Flash/32813561581.html ESP32 (NodeMCU type) Board http://bit.ly/2sOMR3E ESP32 Development Board (Yellow Pins) https://www.aliexpress.com/item/ESP32-Development-Board-WiFi-Bluetooth-Ultra-Low-Power-Consumption-Dual-Cores-ESP-32-ESP-32S-Board/32802136026.html ESP32 X-Shield https://www.aliexpress.com/item/Lolin-ESP32-wemos-ESP32-WiFi-Modules-Bluetooth-Dual-ESP-32-ESP-32S-ESP8266/32807523301.html ESP32 Lolin Board with LiPo https://www.aliexpress.com/item/WEMOS-LOLIN32-V1-0-0-wifi-bluetooth-board-based-ESP-32-4MB-FLASH/32814488554.html ESP32 OLED Board http://bit.ly/2tosirM ESP32 Board with 18650 https://www.aliexpress.com/item/WEMOS-WiFi-Bluetooth-Battery-ESP32-development-tool/32811429908.html D1 mini ESP32 board https://www.aliexpress.com/item/MH-ET-LIVE-D1-mini-ESP32-ESP-32-WiFi-Bluetooth-Internet-of-Things-development-board-based/32816073234.html WeMos Arduino like ESP32 Board http://bit.ly/2tUZVnC Cheapest ESP32 board (source not tested by me): https://www.aliexpress.com/item/Lolin-ESP32-wemos-ESP32-WiFi-Modules-Bluetooth-Dual-ESP-32-ESP-32S-ESP8266/32804853522.html WEMOS Official Store: http://s.click.aliexpress.com/e/jUzBiIq Supporting Material and Blog Page: http://www.sensorsiot.org Github: https://www.github.com/sensorsiot If you want to support the channel and buy from Banggood use this link to start your shopping: https://bit.ly/2jAQEf4 (no additional charges for you) Official Wemos Store: http://s.click.aliexpress.com/e/jUzBiIq https://www.facebook.com/SensorsIOT/ https://twitter.com/spiessa https://www.instructables.com/member/Andreas%20Spiess/

In video #146 we looked on how to test power supplies and battery packs using a very cheap and a quite expensive electronic load. Today, I will test two astonishingly cheap electronic loads with very interesting features: The ZKE EBD-USB and the ZKE EBD-USB+. At the end, you should be able to decide, if such a load is a reasonable addition for your lab, and which one fits better. And you can use them also as data loggers...

Today, this channel will try to start into a new area: The area of the replacement of our beloved ESP8266 by the new ESP32. I invite you to join this journey. At the end of this video, you should be able to judge, if you want to order your first board (or take it out of your drawer) Summary: • We checked the GPIOs out and discovered, that we have many more of them, and that they abandoned the Dx numbering scheme. So, we do not have to write our sketches differently for the different boards. • Then, we looked at the different examples provided with the infrastructure. This will be stuff for many videos to come. Today, we tried PWM and it worked. We were able to generate a fading LED, steer a servo, and even create a primitive DAC with this function. • Next, we tried a simple example to check, if the Wi-Fi really works. And it does. We learned, that we will have to change all our ESP8266 sketches if we want to port them to the ESP32. • Then, I ported my NTP library to the ESP. With one small change, it worked and delivered accurate time also on the ESP32. • At the end, we checked also the new touch pins, and, together with the PWM functionality from the beginning of the video, we're able to create a small instrument. Attention: If your Arduino IDE is installed in the "Program file" area of Windows, you need to run "get.exe" as administrator.

We will look at procedures to test power supplies and Solar Panels using Electronic loads (cheap to expensive). We will cover: - The basic principle of testing of power sources like poser supplies or batteries - The problems associated with it and its resolution - I will show you my new IT8512A+ electronic load and how it works - At the end, we will test a very nice small power supply (DPS5005) with the procedures we learned See also video about DPS5005: https://www.youtube.com/watch?v=QxR-_ZnREQQ Links: ITECH IT8512A http://s.click.aliexpress.com/e/Yr3B2vF Maynuo M9712 http://s.click.aliexpress.com/e/jq3Z7Uv DPS5005 Power Supply http://bit.ly/2fcx2hB / http://bit.ly/2g0nbvX Aluminum Housing for DPS5005 http://bit.ly/2u8b8ms / http://bit.ly/2wzLVBg Additional material: http://www.sensorsiot.org/?p=387 60W Load: http://bit.ly/2u8x00I ZHIYU Small Electronic Load: http://s.click.aliexpress.com/e/6UnYFQB Supporting Material and Blog Page: http://www.sensorsiot.org Github: https://www.github.com/sensorsiot If you want to support the channel and buy from Banggood use this link to start your shopping: https://bit.ly/2jAQEf4 (no additional charges for you) Official Wemos Store: http://s.click.aliexpress.com/e/jUzBiIq https://www.facebook.com/SensorsIOT/ https://twitter.com/spiessa

In video #140 we hacked the new IKEA Trådfri Smart lighting system using the remote control as a basis. It worked, but had some major disadvantages. Today, we will use an IKEA gateway and do it right! - We will eliminate the problems of the current hack - We will install and pair the gateway with two different bulbs - We will learn how the system communicates - We will switch the lights using Node-Red on our Raspberry Pi. Like that, we can use MQTT or many other tools to switch the lights - We will switch the lights with a normal Linux command - We will install a Python wrapper. You can use this wrapper as a basis for your own programs - We will see the CoAP protocol , which was introduced in the last video, in action - At the end, as promised, I will reveal a “hot” secret about the IKEA bulbs. We also will use AdvancedIP Scanner to find the IP address of our Gateway Supporting Material and Blog Page: http://www.sensorsiot.org/145-ikea-tradfri-hack-with-gateway/ Zigbee info: https://faire-ca-soi-meme.fr/test/2017/06/06/ikea-tradfri-zigbee-3-0-compatibilite-zigate/ Github: https://www.github.com/sensorsiot If you want to support the channel and buy from Banggood use this link to start your shopping: https://bit.ly/2jAQEf4 (no additional charges for you) https://www.facebook.com/SensorsIOT/ https://twitter.com/spiessa

In this video, - We will discuss the relevance of the COAP protocol and where it is used - Create an idea about the concept of RESTful APIs I already used in video #27 - Understand the basic differences between COAP and MQTT - Use COAP on ESP8266 - We will learn a little on how to “spy” networks using Wireshark - And of course, we will be prepared to hack the IKEA Tradfri gateway in the next video Links: ESP8266 CoAP Library: https://github.com/automote/ESP-CoAP ETH Zurich CoAP Test Server: coap://129.132.15.80:5683/ Copper Firefox add-on: https://addons.mozilla.org/de/firefox/addon/copper-270430/ Supporting Material and Blog Page: http://www.sensorsiot.org Github: https://www.github.com/sensorsiot If you want to support the channel and buy from Banggood use this link to start your shopping: https://bit.ly/2jAQEf4 (no additional charges for you) https://www.facebook.com/SensorsIOT/ https://twitter.com/spiessa

The invention of radar influenced the way world war two went, because it was possible to detect planes of the enemy and shoot them down. And since then, this technology made civil aviation as we know it possible, because it can detect movement of metallic surfaces over distance. Of course, the technology can also be used against us, for example if we are trapped while speeding… Links: HW-MS03: http://bit.ly/2qffo0R RCWL-0516 (Works also with 3.3 volts): https://www.aliexpress.com/item/RCWL-0516-microwave-radar-sensor-module-Human-body-induction-switch-module-Intelligent-sensor/32704946341.html WB3-12: https://www.aliexpress.com/item/LED-Microwave-Radar-Sensor-3-12W-Microwave-Sensoring-Switch-Special-for-Spherical-Lamp/32602421530.html XYC-WB-D1: https://www.aliexpress.com/item/Microwave-Radar-Sensor-4-8M-180-LED-Lamp-Smart-Switch-Steady-Home-Control/32668622766.html HFS-DC06: https://www.aliexpress.com/item/5-8GHz-Microwave-Radar-Sensor-Module-ISM-Waveband-DC-5V-39-22-11mm-Installation-Height-2/32735312800.html 220V Switch (SK-600): http://bit.ly/2oGt8Sc http://www.rogerclark.net/investigating-a-rcwl-9196-rcwl-0516-radar-motion-detector-modules/ https://github.com/jdesbonnet/RCWL-0516/ Supporting Material and Blog Page: http://www.sensorsiot.org Github: https://www.github.com/sensorsiot If you want to support the channel and buy from Banggood use this link to start your shopping: https://bit.ly/2jAQEf4 (no additional charges for you) https://www.facebook.com/SensorsIOT/ https://twitter.com/spiessa

In this video - We will build a very small LoRa gateway using a RFM95 / RFM95W - It even supports downlink and OTAA - And all parts together do not cost more than about 15$ - Because it works with a ESP8266, we even have a wireless connection to the internet - It is only single channel. But, because it is so cheap, why not build two or three on different frequencies? - The build is very easy, because we can use a ready-made PCB, which is compatible with the Wemos shields. - The optional Neopixels and the OLED display show us the traffic Link: New Version of Gateway (not tested by me): https://github.com/things4u/ESP-1ch-Gateway Sketch: https://github.com/SensorsIot/ESP-1ch-Gateway Alternative Sketch: https://github.com/marcobrianza/ESP-1ch-Gateway-v4.0/tree/LoraNode_1.3 PCB: https://pcbs.io/share/4Q1Z4 RFM95: https://www.aliexpress.com/item/RFM95RFM96-100mW-DSSS-spread-spectrum-wireless-transceiver-module-SPI-SX1278-SX1276-SMD/32245859329.html Wemos D1 Mini: http://bit.ly/2oXSx5X Supporting Material and Blog Page: http://www.sensorsiot.org Github: https://www.github.com/sensorsiot If you want to support the channel and buy from Banggood use this link to start your shopping: https://bit.ly/2jAQEf4 (no additional charges for you) https://www.facebook.com/SensorsIOT/ https://twitter.com/spiessa

In this video, I show you the basic principles of LoRa and LoRaWAN, its plusses and minuses, and also show you my own LoRa gateway and a LoRa client, and send the first message to the things network. Link budget and bandwidth are introduced. This technology can be used for Arduino and other microcontrollers like the ESP8266 or the ESP32. It is LPWAN technology. You find many more videos on how to build gateways and nodes: https://www.youtube.com/playlist?list=PL3XBzmAj53Rkkogh-lti58h_GkhzU1n7U Links: TTN Homepage: https://www.thethingsnetwork.org/ Technical explanations: https://www.youtube.com/watch?v=T3dGLqZrjIQ&t=395s LoRa module: http://s.click.aliexpress.com/e/hQDRc7A Plain LoRa Module: http://s.click.aliexpress.com/e/bqngYvpO LoRa Gateway: http://s.click.aliexpress.com/e/HGHRRio If you want to support the channel and buy from Banggood: https://bit.ly/2jAQEf4 (no additional charges for you) https://www.facebook.com/Andreas-Spiess-733189426841519/ https://twitter.com/spiessa

Here I show, how you can avoid any outside switches at your OTA devices and still initiate configuration and update mode for ESP8266. I am sure, you can use reed switches also in other Arduino projects.

In this video we continue with making the invisible visible. I needed a wireless serial connection to the ESP8266 and used telnet for it. Unfortunately, Telnet and normal OTA does not work together. So, I changed the OTA to webupdates and created an IOTappstore. Relevant other episodes are: #78 for the IOTappstore #72 and #76 for the project #32 for Standard OTA #30 for the ESP-12E programmer In the meanwhile, IOTappStory.com infrastructure uses UDP instead of Telnet. See videos #105 and #109. It is faster and you do not have to reconnect everytime the ESP boots.

In this video I show you how to solve the problem of GPIOs with small currents. The ESP8266, e.g. can only source 12 mA. This is not enough for LEDs to create bright light. Neopixels can be sourced by 5V and still do not draw a lot of current from the GPIO. So, they are much brighter without any driver or FET. In addition, many of these Neopixels only occupy one pin. The PL9823 come in a round shape and can replace LEDs completely. It behaves exactly as the Neopixels. There are many tutorials around how to connect the LEDs: Just connect GND and VCC to each of the PL9823s (3.3 or 5V). Then, you connect the ESP/Arduino pin defined in the sketch to the Din of the first LED. The Dout of the first LED is then connected to the Din of the second LED. And so on. Because you define the number of LEDs in the sketch, you can just go on till you reached the number of LEDs in the sketch. 5 and 8mm: http://www.aliexpress.com/item/10-1000pcs-PL9823-9823-F5-5mm-F8-8mm-Round-RGB-LED-P9823-chipset-inside-RGB-Full/32546693829.html

In this video we talk about the basics of measuring currents. We introduce things like "shunt resistor", "low side", "high side", and "hall sensors".

In this video, I do a first test with this brand new module. It is well suited to build GPS trackers for logistics applications. Together with an ESP8266, an ESP8285, or an Arduino Pro Mini you can build such a tracker for less than 15 dollars. There is also a small introduction into antennas.

In this video I show tools to find out, how a unknown electronic device works. I start with a Multimeter, continue with a Digital Storage Oscilloscope (DSO), and end up with a modern Logic Analyzer. The goal is to build an enhanced electronic load with a nice touch display and data logging.

In this video I test the new Arduino/Genuino MKR1000 and compare it with the UNO and the NodeMCU board with an ESP-12E. I show you how to program it, how fast it is, how much current it draws, and how sketches can be ported from ESP8266 to the MKR1000. Addendum: If you add http://downloads.arduino.cc/packages/package_mkr1000_index.json in your preferences, you get the MKR1000 board definitions and it should stay also with newly nigthly builds.

In this video I will read the angle of the accelerator and brake pedal with accelerometer chips (MPU6090 on a GY-521 board). These signals are then transferred to the digital potentiometer (AD5242) of the last video and from there to the X-Box controller. I use an Arduino Pro Mini to control the whole thing. Video on how to transfer data from Arduino directly to Excel: https://youtu.be/AgJegJ30Pj4 Calibration Sketch: http://42bots.com/tutorials/arduino-script-for-mpu-6050-auto-calibration/

In this and the next episode I try to convert a real racing car into a simulator for rental. It already works, but I want to enhance it and replace mechanical parts with electronics. In this episode, I try to replace the mechanical potentiometers of the X-Box controller by a digital potentiometer (AD 5241 / AD5242). I will use an Arduino for the signal processing. In the next episode I will try to translate the movement of the pedals into digital signals. Link to the promotional video: https://youtu.be/_7nZREVVf_w

In this video I connect my ESP8266 to the world. I build a MQTT connection to Adafruit.io and from there, to ,my IPAD, to IFTT and to a node-red instance hosted on IBM bluemix service. I also show why this is one of the simplest concepts to solve the connection problem from behind your firewall to the internet. For my tests, I used three different MQTT client libraries: https://github.com/i-n-g-o/esp-mqtt-arduino http://pubsubclient.knolleary.net/ https://github.com/adafruit/Adafruit_MQTT_Library Witty Board: http://s.click.aliexpress.com/e/EY3GoAy They are all included in the Arduino IDE.

In this video I continue with the software part: establish a protected to-way communication with acknowledgements and defining data structures. I show how you can test the performance of a connection and give you some hints for increasing the range of the devices. This communication system is used in my robot to transfer commands in one direction and telemetry data in the other. The software used for this episode is on github: https://github.com/SensorsIot/NRF24L01-Bi-Directional-Communication

NRF24L01 chips use the 2.4GHz band. This band is used by many other devices like Access Points or Smartphones. In this video I show how to find empty channels and discuss all the prerequisites for a successful communication between two NRF24L01 modules. In the next video I will continue with the software part: defining data structures, establish a protected to-way communication, and give you some hints for increasing the range of the devices. This communication system is used in my robot to transfer commands in one direction and telemetry data in the other. I use the Arduino IDE and the built-in RF24 library.

In this tutorial I show and explain how to create your own watchdog to stabilize your ESP8266 "Thing". It is applicable for all modules like ESP-01, ESP-07 and ESP12 /ESP-12E. And I show different concepts of writing responsive code without using the delay(); statement. You will also find a very brief introduction to interrups and timers including the ticker library. This is the last video of a series of 5.

In this tutorial I show and explain how to upload sketches without serial cable over WiFi. This is awsome if your module is not easily reachable. Currently it only works with ESP-12E and NodeMCU 1.0 (both have 4 Mbyte flash).

In this tutorial I show and explain a simple framework for the ESP8266 to enter initial data with a smartphone or laptop using HTML pages. I also show how data can be permanently saved and retrieved from the EEPROM. I also show how you can get precise time from a NTP server. The code is on github: https://github.com/SensorsIot/Internet-of-Things-with-ESP8266 This episode is based on the great work done by John Lassen. http://www.john-lassen.de/index.php/projects/esp-8266-arduino-ide-webconfig All programming is done in the Arduino IDE Supporting Material and Blog Page: http://www.sensorsiot.org Github: https://www.github.com/sensorsiot If you want to support the channel and buy from Banggood use this link to start your shopping: https://bit.ly/2jAQEf4 (no additional charges for you) Official Wemos Store: http://s.click.aliexpress.com/e/jUzBiIq https://www.facebook.com/SensorsIOT/ https://twitter.com/spiessa

How do you program an ESP-7 or ESP-12 module if it is soldered onto a PCB in your "Thing"? In this video I show my proposal using pogo pins. I also show how I create the timing to set the ESP8266 automatically into programming mode if the Arduino IDE starts to upload. For this solution, I use an Attiny85.

This is the first part of (I hope) 4 where I try to build a software framework for small connected IoT devices. The software is based on the Arduino IDE In this episode I build a small device which calls a RESTful API to get the next public transportation from my location and starts to warn me with a beeper when the bus arrives. The episode shows all needed steps to build such a device and other web-services can be used using the same principles. In the next episode I will connect the ESP8266 to my smartphone to exchange data like access point name and password.

I show how to program a PID controller to be used to stabilize the speed of a motor. To show the effects of the different factors on the result I test it in reality with the fan of my wind tunnel. The PID principle can be used for many other applications where unstable systems have to be stabilized.

In this video I show my toolchain from idea to print. I start with the 3D drawing on Solidworks and show some tricks I learned the hard way. As a next step, I slice the files with Simplify3d and transfer it to the printer using Toshiba Flashair WiFi SD card. I show also how you have to setup the Flashair in order to use it with the 3D printer. At the end I show you some of my prints and projects as examples. Link to Flashair: https://www.flashair-developers.com/en/

In this video I show how I get good adhesion for my PLA prints. I show how I mount a new Kapton tape and how much adhesion I get by using cheap hairspray. It is not necessary to reduce the printing speed for the first layer. Source of my Kapton Tape: http://www.aliexpress.com/item/Free-Shipping-200MM-33M-Gold-BGA-Tape-PCB-tape-Thermal-Insulation-Tape-High-Temperature-Resistant-Tape/1104399281.html I show it on my Wanhao Duplicator 4x 3D Printer

When I print unattended, especially during nights, I want my printer switched-off when it is finished. I show you how I built an auto-shut-off function for this purpose. In its off-state it does not use any electricity. I use the same principle as I used for the hot-glue Gun in a former video: https://youtu.be/2SVzzAe2HBY The sketch, a diagram and Eagle files are on Github: https://github.com/SensorsIot/3D-Printer-Auto-off-Switch The Video about the assembly of my Wanhao Duplicator: https://youtu.be/jn-CQgi_SAc I also use the same parts as I used for the hot glue gun timer.

This video shows how to use Arduino interrupts to measure the speed of a strong 4 wire fan. It shows also the steering of the RPMs by using a PWM signal. And it measures the transfer function of the fan. The fan is part of my Wind Tunnel Project. In the next video I will close the loop with a PI controller programmed into the Arduino to stabilize automatically a choosen RPM.

In this video I test my new USB microscope if it corresponds to the specifications and if it is useful for my daily work. Especially I try to use it for SMD parts recognition and solder joint inspection as well as for soldering of SMD parts. I got my microscope from Aliexpress: http://www.aliexpress.com/item/Hot-sale-8LED-800X-USB-Microscope-5-0-mp-Digital-USB-Microscope-Portable-800x-Microscope-Aopute/32348853749.html

In this video I compare the "old" Neo-6M with the new Neo-M8N module. I am interested especially in altitude precision, but compare also horizontal precision. Both modules are compared with the precision of a pressure sensor BME280 in measuring exact relative altitude. I also show how to change the Arduino TinyGPSplus library that it works with the Neo-M8N module.

In the previous tutorial I showed how to connect several devices to the same I2C bus. All devices had to be different (different sensors, different displays): https://youtu.be/QQLfzlPGjjE Here I show how you can connect two devices of the same kind to one I2C bus. This needs a few steps more. I use two Heltec SSD1306 OLED displays and a BMP085 for the demonstration. The content can be also used for ESP8266 or for STM32 Boards like the Maple Mini.

This tutorial shows how you can connect many devices (sensors and displays) to one Arduino using the I2C bus. It starts with a simple hommade bus, shows how to find out the addresses of the different devices and ends with a demo of a system with three devices connected to an Arduino Uno: A BMP085 pressure sensor, a MPR121 touch sensor, and a SSD1306 OLED display. The tutorial applies also for Attiny, ESP8266 and STM32 boards like the Maple Mini Links: Level Shifters: http://www.aliexpress.com/item/10pcs-lot-IIC-I2C-level-conversion-module-5V-to-3V-System-Compatible-Module-Dedicated-Free-Shipping/1368899581.html I2C Scanner http://forum.arduino.cc/index.php?topic=197360 Example Sketch: https://github.com/SensorsIot/I2C_1-Video

I plan to build a bicycle power meter using the priciple of "opposing force, (OFPM)". This takes into account gravity, wind resistance, inertia, and rolling resistance. I want to mesure these parameters using an Anemometer, a BME280 pressure sensor, a GPS module and display the results on a Heltec SSD 1306 OLED display. The processor I use is a Maple Mini. I use the Maple instead of an Arduino in this project because it is faster and can calculate with double precision numbers. In this episode I test the first prototype which already can measure altitude and speed. The next episode will be about measuring wind speed.

The ADS 16bit ADC is introduced and used with an Arduino Leonardo. I compare it with the built-in ADC in an application to measure current with a hall sensor. These sensors produce quite weak signals and therefore need an precise ADC. The evaluation is done as usual in Excel using the Keyboard.print() command. Because it uses I2C bus it can also be used for ESP8266 or for STM32 boards like the Maple Mini.

I upgraded my Laptop to Windows 10 and tested, if the Arduino IDE environment still works. I tested with: Adrduino Uno Arduino Due (32bit) ESP8266 Maple Mini (STM32) Attiny85 See my results in the video and decide if you want to do it too. Installing Unsigned drivers in Windows10: https://youtu.be/StkR3D2d5WI

Exact determination of altitude by measuring pressure is needed in many applications. I compare three generations of pressure sensors, the BMP085, the BMP180 and the BME280 from Bosch and find out, how exact they measure. I use an Arduino Due and a Maple Mini to calculate the results and export them into Excel for analysis. The Library used for the BME280: https://github.com/embeddedadventures/BME280 The Library used for the BMP085 and BMP180: https://github.com/sparkfun/BMP180_Breakout

In this project I build a timer with an accoustic notification if temperature for gluing is reached. It switches the gun automatically off if not used for 10 minutes. When off, it uses absolutely no electricity. The design uses an ATiny85, a solid state relay and is programmed with the Arduino IDE. Code and Eagle Files on Github: https://github.com/sensorsiot

To build small devices is fun. This is why I built a 1.5V battery tester using an Attiny and a cheap SSD1306 OLED display from heltec. The device measures automatically batteries with and without load (with a MOSFET). I found a small Arduino OLED library and adapted it to work with the TinyWireM library for I2C communication.

I often use cheap prefabricated Dupont wires in my Arduino, ESP8266, STM32, or Raspbery Pi projects. This enables "professional" looks without crimping the wires myself. Here I show five tricks to increase the quality of your projects as well as gain time in cabelling the parts together. I use only simple aids like Super Glue, tweezers, and empty Dupont housings or shells. Please watch my update before you purchase a crimping tool: https://youtu.be/3Cw9YFLDZeo Empty shell assortment: http://bit.ly/2lFJXb6

A race between several Arduino compatible boards below 10$ shows how fast the boards are and how much energy they use. The results are quite interesting...

Here I show a trick to increase the precision of the arduino analog readings just with software. No additional hardware needed. Source of the trick: http://hacking.majenko.co.uk/making-accurate-adc-readings-on-arduino The coding used by me is on Github: https://github.com/SensorsIot/ADC_Test.git

I build a Datalogger with keyboard input to Excel. It can measure volt and ampere and two additional analog signals. I use it to check-out the buck converter of my previous video. As promised, I use here the prototyping PCB aproach to build it. I enhance also the precision of the built in analog-to digital converters (ADC) of the Arduinos. The coding is on Github: https://github.com/SensorsIot/Data-Logger-with-Excel-connection.git Here you find the source for the precision incres for Arduino ADCs: http://hacking.majenko.co.uk/making-accurate-adc-readings-on-arduino

Will my new ORICO Docking station live up to the expectations? I testet its performance and compared it with a direct SATA connection and with a cheap SATA-to-USB cable.

This tutorial shows the functions of the buck converter (step down) with tree trimmers. It also reveals the secret of the middle trimmer and it tests the efficiency of such a converter in different situations.

I show how I build my prototypes "on the fly" using Dupont wires, pin headers, heat shrink tubing and hot glue. And I reveal some tricks which help me on a daily basis. I use my Morsetrainer project as a show case. Good video om crimping: https://youtu.be/GkbOJSvhCgU

If your soldering station does not work anymore it is possible that you have to replace the heating element. I show here how you can diagnose and replace it if necessary. A good explanation on how heating elemens work: https://youtu.be/g78f-tJ666c

Normal random generators produce streams an even propabilities. Here I present an algorithm to get variable propabilities. The random generator is used in a morse trainer where the trainee trains with the letters he does not know well. The algorithm can also be used in other situations. Code on Github: https://github.com/SensorsIot/RandomGenerator

Explanations to the coding of the self-adapting Morse trainer introduced in part 1 https://youtu.be/F8BddxBPplc Code for the project: https:github.com_SensorsIot

This (receiving) trainer automatically adapts the training speed and the likelihood of apperance of letters to the capabilities of the trainee. This is the fastest possibility to enhance your morse skills. Code: https://github.com/SensorsIot
