A highly optimized Art-Net and sACN pixel controller for GD32 Cortex-ARM microcontrollers, built around a Timer → DMA → GPIO architecture for deterministic timing, minimal CPU overhead, and maximum output efficiency.

Success (well, 80%) with my first real soldering-required project!

I have a board with components that can power three (different) Neopixel shapes in a (prototype) Lego enclosure.

Need to make lots of nice 8x8 pixel art and fonts now though, and get a properly designed Lego box.

The only problem is a wonky connector for my third Neopixel — I'll have to resolder that.

I also have software so that I can change everything through Wi-Fi.

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.

Soweit, so gut. Der Kegelaufsatz ist nun auch beleuchtet, die meisten Verbindungen verlegt.
Fehlt nur noch der #ESP32 in der Bodenplatte und dann kann ich die #Weihnachtspyramide einmal komplett aufbauen.

@cjdell I've gone down a different route. I've bought some #ESP3-S3 minis instead. The one I plugged into a breadboard is connecting fine to my WiFi. Also, I was having problems with a #GurgleApps #WordClock #NeoPixel mucking up the display and I have none since swapping over 6 hours ago :-)

3. Ebene fertiggestellt und mit fliegender Verkabelung getestet. Mit nicht mal 150 mA ist das auch noch im Rahmen als Dauerverbraucher, wobei ich den Programmcode später noch ein wenig ausbauen werde.
Nun wird's aber langsam Zeit fürs Bett.

Спасаем ARGB: Как я заменил сгоревший китайский хаб на ESP32 с веб-интерфейсом

Год назад я собрал систему с пятью бюджетными ARGB вентиляторами Aigo AR12 с 6-pin разъёмами. В комплекте шёл хаб AR12-2012 — типичная китайская плата с 5 портами для вентилей, SATA питанием и выходом на материнку для синхронизации подсветки. Всё работало. Красиво светилось. Но ровно год . Однажды утром вентиляторы крутились, а подсветка — нет. Хаб умер. Покупать новый за $15-20 не хотелось, тем более что я знал: внутри этих вертушек сидят обычные адресные светодиоды (WS2812/SM16703-совместимые). А раз адресные, значит можно управлять с ESP32 .

Any #NeoPixel #led diffusion ideas? I think I’m going with the second option - butcher paper - but thoughts & ideas are welcome! https://youtube.com/shorts/at8DyoaGis8?si=XgDWPUbJX9svUGhn
No diffusion prosper diffusion? Also comment if you have ideas on better diffusion

After some discussions here and elsewhere, I've decided to attempt integrating some #PixelBlaze hardware into my project. This will free up 6 DIO pins on the #microcontroller, allowing direct UART connection from the LoRa node.

Plan now is to use a Pixelblaze with their 1 to 8 Output Expander to work out control signaling. Then, produce that signaling from my hardware. The Pixelblaze will be a sort of test jig to use its web UI to write & test.

This way my project can be kept a degree more simple, and I can still trigger various display output depending on different conditions of the bicycle. (One #Neopixel "strip" will be a tail/brake light.)
