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.

Grundig RGB lamp with ESP8266

the plan

  • Disable the shitty mcu inside the lamp (done)
  • Solder wires to the vcc, gnd and pwm pins (nearly done)
  • Connect a ESP8266 to it with nodemcu and some lua sauce
  • ????
  • Profit!

control mcu pinout

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

               -------------
              |   o         |
 vcc      ----| 1         5 |----  gnd
 red pwm  ----| 2         6 |----  blue pwm
 ?        ----| 3         7 |----  green pwm
 ir rx    ----| 4         8 |----  ?
               -------------

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
