Inspired by my last #WS2812B #PCB, I decided to do a smaller version and try to add a USB C connector. I'm very pleased how it turned out. The LEDs are not as close to each other as last time, but I still used my hot plate to solder them. And hot air for the back side.
Again, manufactured by @aislerhq and designed using @kicad

My partners kindle is dying. I thought it would be cool to give her min and build myself one. Pretty intimidating project though.

Cool example:

I was thinking perf board based with a pico.

Ever wondered how a diode actually works? 🤔⚡️

It’s the "one-way valve" of electronics, but there's so much more going on inside! In my latest video, I break down the P-N junction, explain Forward vs. Reverse Bias, and compare common diodes like the 1N4003, Schottky, Zener, and LEDs.

Watch the full breakdown here: https://www.youtube.com/watch?v=a9LnNkGxeyQ

Here are the boards! I soldered a first one by hand, but the #WS2812B #LEDs are very close to each other. So some have burn marks. Hot air is no option, it would burn them up. So, I bought a hot plate and tried again. It's so much faster and easier! And it worked directly after #soldering.
I only need better solder paste, this one was difficult to clean.

the beautiful boards as they came from Aisler. there are two pixel hearts on the silkscreen, reminding of Minecraft heart symbols

the first, hand soldered board. some of the LEDs have burn marks since they are so close to each other.

the heart LED board in action, showing a rainbow color palette.

the second board was soldered using a hot plate. the LEDs are unscathed and it was finished a lot quicker

Ich hab da was gebaut…

Mein Männerballet braucht für die Auftritte einen trippy Pilz. Ich bin super happy damit. 😍

Irgendwie wird das USB-Kabel leicht warm. 😆

Built a Photonotron by @noisio today. A small, light-controlled synthesizer. Takes an hour soldering, when you don't know it, maybe, but only 10-15 mins to build, when you do. More importantly this is an instant gratification project for people, who like to freely play. The synth has a lovely audio quality (via cable to a large boombox ;) - we haven't stopped playing this and performing with it (it applies to dancers, too!) for the whole day. Lovely, lovely, 200% recommendation,

I have this tiny Bluetooth transmitter module. The connectors have half the pitch of the usual pitch on bread boards and are difficult to solder. What’s the easiest way to prototype stuff with these tiny connectors. #electronics #diyelectronics

Bring Back the Magic of Radio! 📻✨

Ever wanted to broadcast your own audio over the AM band? I just came across this fantastic DIY guide by VU3DXR on how to build a Micro-Power AM Transmitter.

Check out the full circuit diagram and step-by-step instructions here: 👉 https://vu3dxr.in/build-your-own-micro-power-am-transmitter/

I fixored my Hamilton Beach toaster. 🪛 :neocat_solder:

The solder joints on the electro magnet that holds the lever down had broken completely.

Since it'll take some time for the PCBs to arrive, I decided to make a #prototype on #perfboard. It works fine, and I can test my programs using it. Turns out an #ATtiny814 is good enough for the task.
The #WS2812B #SMD #LEDs are very bright, though, and reducing brightness also reduces the possible color range.
The different color shadings are not very distinguishable, yet. I might have to adjust the color palette.

the back side of the perfboard prototype. there are lots of ceramic capacitors arranged in a heart shape. a few jumper wires are visible, with the insulation red, black, white, and without.

the front side of the perfboard prototype. there are 34 WS2812B SMD LEDs, arranged in a heart shape.

My Soviet Germanium PNP class A transistor audio amp works! Needs a little tuning but sounds pretty good! Definitely “old Fi” rather than hifi but that’s what I wanted. This was based on a circuit from MIT but seriously modified b/c of the transistors I had available. I’ll post a schematic. Very happy I got this working well!

Transistors are 2x MP-39 for voltage gain and 2x P-214G Darlington power transistors driving 8ohm cheap speakers.

Nothing annoys me more than people who peek at their Christmas presents early. I built a "Present Peeker Trap" that sounds an alarm, records and video, and pings my phone if someone peeks!
