Right, whatever. I pulled all electronics out, soldered a Wemos D1 mini inside and 10x SK6812RGBW leds and i used my existing art-net code. Done :D

Inspired by madeddie's ESP mission, i dug up this old project and attempted to finish it.
Had it working on breadboard so moved to put it inside the actual lamp. Doing so I seem to have broken ~something. Currently debugging.

Funny bit is, the PWM signal is actually inverse. So they output a high signal to turn off the LED, and a low signal to turn on the LED. This can be proven by grounding one of the pwm output pins, which turns on the respective color of LED.

control mcu pinout

This is the unmarked IC labelled U1 on the silkscreen. , vcc is 4.24-4.3 volts

 vcc      ----| 1         5 |----  gnd
 red pwm  ----| 2         6 |----  blue pwm

Funny bit is, the PWM signal is actually inverse. So they output a high signal to turn off the LED, and a low signal to turn on the LED. This can be proven by grounding one of the pwm output pins, which turns on the respective color of LED.

consideration

  • Make wifi foolproof, webpage style config and 'robust'
  • Do fancy fades inside the ESP8266 ?
  • Lower voltage a bit (about 0.7V?) to power the ESP8266
  • Pray the pwm output has enough umpf
