Управление освещением с помощью любого USB пульта по Modbus RTU
Добрый день коллеги. Я думаю многие, кто читает эту статью, сталкивались с проблемой найти визуально красивый пульт для управления основными функциями в системах автоматизации. Несколько дней поизучав дизайн zigbee пультов и радио канальных брелоков я наткнулся на интересный сегмент недорогих USB пультов от 500р, которые все обошли стороной. Поговорим подробнее как их можно внедрить в системы управления не только презентациями, но и чем угодно, начиная от ламп и штор в "умном доме" заканчивая управлением станками.

Got the start of an #ARGB #WS2812 signal parser working using #RaspberryPi #RP2040 PIO. Going to use this with my #OpenRGB RP2040 ARGB splitter project to send configuration data (LED channel counts) using a standard ARGB controller output. RP2040 PIO is awesome for dealing with high speed serial signals!

Bluetooth speakers and headphones often need more than the chip's built-in resources. The JL JieLi AC696N's SPI interface allows you to add external Flash, an LCD display, and RGB LEDs.
All these configurations can be validated on the AC696N development board before porting to custom hardware. Once working, they significantly expand the capabilities of your audio product.

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.

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 .

I've spent way too much time investigating why my #ws2812 RGB LED strip driven by #esp8266 with #wled firmware is only lighting up roughly half way.
I was checking wiring guides and signal strength, modding the level shifter as per https://wled.discourse.group/t/levelshifter-analysis/11871/12
Before I realized I bought a longer strip (5m) than I was calculating with (3m)...

Published the #WLED #ws2812 matrix projector on printables:
https://www.printables.com/model/1470198-ws2812-8x8-projector
it uses resin printed optics as well as a cheap Fresnel magnifier lens to project 8x8 LED matrix modules running WLED.

RFC/thinking out loud: Powering Portable Projects
I want to power several 1m long #ws2812 RGB strips from power bank(s) for not a lot of money. The LED specs say 60 LEDs per meter and 60mA max power draw per LED. That's 3.6A/m (18W at 5V).
Affordable USB-C cables are rated for 3A only. What if I take one of these PD trigger boards (0.8€/pc) to request a higher voltage (e.g. 12V), and then use a small buck converter (also 0.8€/pc) to bring it back to 5V. Supposedly it supports 5A out.
