Testing something else (reusing the small matrix I made as proof of concept for the bigger one).
It's nothing original, but it looks nice. ;)

And it will probably be better with thinner acrylic sheet and better led placement.
I guess I have to make a pcb and order some 2mm acrylic sheets :)

Finally found some time to bring my #NeoPixel Heart PCBs into a usable state and add some documentation. The #sourcecode is hosted on @Codeberg at https://codeberg.org/rommudoh/NoisyMcHeart and works for both variants (big and small).
I think I'll publish the #KiCad files soon, too.
Thanks to #platformio I can use the same code for both hardware variants.

#DIY Ich möchte an ein Netzteil (Ausgang: Kabel) die Spannungsversorgung von 6 #LED Streifen #WS2812B mit möglichst geringem Aufwand anschließen. Löte ich die einfach alle zusammen und mache einen Schrumpschlauch drüber oder gibt es da was smarteres?

Driving WS2812Bs With Pure Logic

The WS2812B has become one of the most popular addressable LEDs out there. They’re easy to drive from just about any microcontroller you can think of. But what if you have a microcontroller a…

I've not been very vocal on here in a while, but it feels good to see some familiar faces popping up in my feed again. Here is a project I've been working on. Meet #PixelClock! It's all #3Dprinted and just holds a strip of #WS2812B LEDs (60LEDs/M) and an ESP32 WROOM running custom firmware that I've been working on. I'll share files on #prusa #printables soon™ #3dprinter #3dp #pixel #pixeldisplay #maker @makemagazine

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

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.
