My first take on MicroPython and the new Raspberry Pi Pico W. Had some struggle wit the lacking ram but at the end a simple screen share worked which allows you to project anything shown on your PC screen to a nice LED Matrix display wirelessly. The case with back projection screen is printed in one Piece. It's a super simple project to make on a weekend. I have better Websocket versions coming so subscribe to not miss that.

I needed an upgrade for my solar setup since the utility bills got outrageous. The cheap grid tie inverter is easy to setup and saves me 1€/day now. I tested the microinverter and it's working fine making 3kWh/day with two 300W panels. The highest output I measured with my clamp meter at was 2A AC which corresponds to about 520Watts. That's nice because I didn't spend a penny for the mount. The app allows to control the output so you can limit it if you need. New merch is here! https://merch.bitluni.net/shop In Germany the inverter can't exceed 600W so be cautious: https://www.vde.com/de/fnn/arbeitsgebiete/tar/tar-niederspannung/erzeugungsanlagen-steckdose Links to parts and tools (affiliate links): - The shop for the 700W inverters I got with app: https://aliexpress.bitluni.net/gridTieShop - Micro Inverter with plug and no app 600/700W: https://aliexpress.bitluni.net/gridTieInverter - The same Inverter on Amazon EU for 200€ https://amazon.bitluni.net/gridTie700 - Flexible Solar Panels: https://aliexpress.bitluni.net/flexSolarPanel Drone DJI Mini 3 pro: https://amazon.bitluni.net/drone Camera and lens (4k 60fps): https://amazon.bitluni.net/gh5 Zoom H6 Audio Recorder: https://amazon.bitluni.net/h6 plz share :-) Github Sponsors: https://github.com/sponsors/bitluni Patreon: https://www.patreon.com/bitluni Channel membership: https://www.youtube.com/channel/UCp_5PO66faM4dBFbFFBdPSQ/join Paypal: https://paypal.me/bitluni Twitter: @bitluni Discord: https://discord.gg/MT5RbJt #solar #diy #microinverter

I was bored! All my other projects end up dragging so I decided to build a pocket bike and give me a time limit and concentrate on the most important parts. A pocket bike is basically a mini electric motorcycle. This one even has a dual drive which makes it not only more expensive than needed but also insanely quick. I still didn't find out the top speed. Unfortunately I didn't have enough time to brakes. Keep it safe peepz, I'm a lunatic. Here some details about the bike: It consists of two 1000W 48V BLDC motors. Two VESC-like controllers. 4x6S 6.2Ah LiPo two batteries in series for each motor.

This project demonstrated how basic display can be converted to display stereoscopic images that don't require any extra glasses. A simple lenticular lens can be 3D Printed using a resin based printer and placed on top the display. Several images are interleaved but only one is visible from a each viewing angle. Since the eyes look from different angles two different images can be displayed creating a stereoscopic image.

This LED lamp is a quick project that can be done within a day. Only a few cheap components are needed to create a nice looking ambient lamp. No programming is needed, only the WLED firmware is uploaded to a micro controller via a simple tool. A 3D-Printed version simplifies the build process a lot but the cardboard version is also quickly made and can be made huge in size. WLED is open source and provides many IoT interfaced including a web front end and an app that allows to control all the lamps in the local WIFI.

This part explains how ADSR envelopes work. Unfortunately we hit the limits of the gcc optimizer and and the performance issues force us to go down to 11kHz sampling rate :( This means no further features like LFO etc until we switch to assembler but then just few would be able to follow. Sorry folks.

This a short explanation how a PWM DAC works. It is a kind of technical background knowledge you might be interested in for some upcoming sound synthesis projects. It also shows a simple low pass filter. Next video will be about the R-2R resistor ladder.

Short project - long video. But it is more educational this time providing some info about analog handling of sound and where noise comes from when you try to record using your computer.

Wish you a happy new year... I will never try this again after this fail :)

My shelf was too crowded and I was always searching for tools. A simple steel shelf drilled to the wall with some cheap rubber magnets solved it. It can even be used as a whiteboard. I also added some spare Neodymium magnets to the non magnetic tools. Keep in mind there is also a disadvantage: Your tools will be magnetized permanently and everything will stick to them.

It can be also controlled from the mobile phone. I will give you an update as soon I get a Android 4.3+ phone. Source code here: https://github.com/bitluni/noWorriesKeyFob To learn more about the Bluetooth modules I am using please watch this playlist: https://www.youtube.com/playlist?list=PLjUbKCHhzPEy5dh0gXNUEl3-JLvPpUt2q UART code used from my MIDI device: https://www.youtube.com/playlist?list=PLjUbKCHhzPEy5dh0gXNUEl3-JLvPpUt2q Stuff for the HM-10 modules can be found here: http://www.jnhuamao.cn/index_en.asp?ID=1

Follow up video how to configure two HM-10 (and higher) modules to communicate over Bluetooth. The two base modes of the HM firmware are explained: 1. Transmission mode sending all incoming UART data to the UART of the other module 2. Remote control mode sensing and controlling the IO pins of the other module IMPORTANT NOTE: You might need to send AT+CLEAR to pair the master to another HM-10 module, once it was paired. Tune in for some practical mini projects using this features and more videos that will spot on implementing own firmware.

Finally after two months, the new part where I just concentrate to show you a simple way to accomplish the first serial connection and control with the HM-10. Check out the next part where I show how to communicate between two of them. Download site of the HM-10 manufacturer: http://jnhuamao.cn/index_en.asp?ID=1

Soldering tutorial of the surface mount module HM-10 (CC2540 Chip) on a self etched breakout board. Enjoy this chill pill... Music cc-by: theDICE - Lookin' for clues http://ccmixter.org/files/TheDICE/40484

This video handles the flaws of the mechanical design. Have fun counting the "uhms" and "yeahs" in this part :D

The final practical part of the device development so far. There is always something not working on the first try so I had to do some debugging and fixing.

Development process of the main board of the device.

This is the summery how I developed the multiplexer board. I failed really often but didn't give up until it was done. It felt like it was cursed. I guess this is how you learn things. Details on the wiring and the software will follow in a separate theoretical video.

This is an overview of the build process of the device. I will explain the electronics in detail in follow up videos. Get the source code for the microcontroller and a stripped MIDI code version from my hompage http://electro.bitluni.net/midi You have to excuse the low video quality. I didn't have the HD-camcorder yet when I started the project half year ago. Music: CSoul - Dark Helical Circle http://ccmixter.org/files/CSoul/33614

Intro to the video series about my self build MIDI organ pedals. It was the first big project this year which arouse my interest in building up my lab and do more electronics.

"Short" explanation how the third contact on one cell lithium polymer packs(3.7V) is used for temperature sensing. If your pack has more than 3 contacts it has probably more cells (higher voltage). More contacts are needed to balance the single cells while charging. This video has it's flaws, but it should give you a rough insight of the techniques used there.

Received the smallest RGB SMD LEDs you can get on the market for about $0.08 each. Can't wait to build a small display using them.

I hate those leaky NiCd drill batteries! They are always empty! You can just connect to any 12V Source like car battery or bench power supply which are capable to deliver more than 5 Amps. You can put some of the lead-fleece battery in your belt bag and are prepared to drill down a complete hangar. music cc-by: Papa_Zulu - After the War (PZ Doomed Remix) http://ccmixter.org/files/Papa_Zulu/33767

After a whole day of editing you can finally enjoy my PCB etching tutorial. Etching at home isn't really very difficult. You can even get the chemicals from an online store, since they aren't very dangerous. You might have to give the shop a note, that you are not using it to build a bomb (at least in Germany). Give it thumbs up if you liked it and subscribe if you like more of this. music: _ghost - Cold Theme (Unlimited Bass Edition) http://ccmixter.org/files/_ghost/25388 An etching time lapse of an previous design: http://youtu.be/ely1FYVfE0Q P.S.: If you don't know what I meant by the guy in Robocop just search the interwebs for "robocop acid bath" (caution: I had nightmares as a child from this scene) And also if you don't know Breaking Bad... then... then... seriously?! I wish I could delete my memory and watch this awesome series all over again.

This vid shows how easy it is to exchange a broken display of your phone. You can just order the replacement part and do it yourself. In this case i did it with my Sony Xperia Mini. What happened was that it got wet and then I could see the water in the back of the display just before it stopped working. It did the vibration when turned on, but display was black. I assumed, that just the display was broken and I was right. Repair took 20min with explanations as you see and did cost me $15.50 for the part. This is way cheaper than a new phone.

Got new delivery from China. It was second attempt of the seller to send the item. See for yourself...

This is the second part of the PCB design for toner transfer using DipTrace. Quite simple one side solution fanning out the HM-10 pins to standard 2.54mm headers fitting on a breadboard. Music (cc-by): Two Swords by _ghost http://ccmixter.org/files/_ghost/26146

Creating a pattern for a component is a step has to be done once if it does have a non standard pattern like for the U-shaped HM-10. Since this part already had 13 minutes I had to split the video into two parts. See it like a tutorial.. it's quite useful.

My first intention was to report about my experience ordering parts in china, but since it's so much fun and I receive mail almost every day I started to record it and will show the unpacking and maybe a first short test of the parts I get. Happened to be some fail in this video, but I corrected it with text... please flame me in the comments

Yeah... kind of dull. But more practical episodes are coming. Flame me in the comments...

This is the intro to this new series where I do my best to master some Bluetooth hardware with my limited skills in hardware design. Just check this playlist from time to time to get the latest updates and have some fun! If you aren't interested in design, etch and solder tutorials skip to part 06: http://youtu.be/UNETjvmmQx4

Vid to watch if you can't fall asleep. Let me bore you to death with my Ouya controllers unboxing and thoughts on them. People which were waiting for their console and controllers will understand why I needed to do a 14min video on this. See this follow up for sticking button fix http://www.youtube.com/watch?v=S8NONPw86Is Place your flames in the comments.

See a quick solution I came up after was annoyed by the sticking buttons of the Ouya controller. 3 minutes including explanation what is happening. If you want more, see this loooong unpacking and comments on the controllers: http://youtu.be/BgAzNxrSfp8 Subscribe for future game development tutorials (Just started this channel)

Music: Drops of H2O ( The Filtered Water Treatment ) by J.Lang (CC BY 3.0) http://ccmixter.org/files/djlang59/37792 This is 32x time lapse of etching a PCB using sodium persulfate (Natriumpersulfat). 50g Na2S2O8 + 250g hot water. It was kind of slow this time. I guess the water could be hotter. Recommendation is 50°C. I got once faster results using almost boiling water. I used toner transfer and supported some thin parts using a marker. The PCB is a breadboard fanout for the HM-10 BLE module with TI CC2540 chip. Subscribe my channel to see some applications using Bluetooth in future.

Clip why you should stop deliver firmware on CD/DVD. Please leave it where it belongs: the last century. Correction: there are no drivers. Just the additional manual and the software I used to create this clip. The camcorder itself is really great, I might do a separate review after using it a while. Please flame me in the comments about how this one shot clip sucks... but don't forget to subscribe for upcoming nerdy vids.
