I have put the gate LED rings on Tindie now.
https://www.tindie.com/products/revk/led-ring-gate-style-with-552-ws2812-style-leds/
Sorry about the cost - the LEDs are cheap but there are 552 on each board... #WS2812 style, 3.3V to 5V.
3D models for the gate are on @Codeberg, as are @kicad PCBs to order yourself. All #opensource
What is crazy is moving to the larger LEDs (1.5mm x 1.6mm) from the smaller (1x1mm) actually allows me to do more LEDs in some cases as I can fit vias under the LEDs. It also helps moving the caps to 0201.
This used to be 88 LEDs, and is now 101 LEDs, in a 32mm ⌀ PCB (designed for IronMan gloves, believe it or not!).
The serial LED strip stuff on ESP IDF is pretty good, a standard library. e.g. neopixel, etc.
It used RMT (IR Remote Control) to generate the series of pulses.
But a better way is to use SPI. And the library now does that too.
But I wanted something the library does not do.
Ability to have a strip that is, say, RGB, linked to another that is RGBW. Send 3 bytes for first X pixels and 4 for the rest, etc.
So, ended up making my own SPI based serial LED driver.
Yay, it works.
in case you're still using those, read my rant on this flavour of addressable RGB LEDs, an why I prefer SPI based #APA102 and #SK9822

Mignon. (un peu comme dans VLC...)
This is what happens, if you leave me alone with an #ESP32, a #WS2812 LED-Strip and some time.
I have not yet implemented it to display maintenance times. I believe #UptimeKuma will internally handle that as up and note the maintenance somewhere else, but I'm not fully sure.
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 .
