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
