CHDK shutter from GWS ICS50 brushed speed controller
As the title says.
Very simple, remove the heatshrink and the aluminum sticker heatsink, unsolder all the power wires and solder the USB wires to the power outlet, the 5V supplied by the RX will trigger the camera.
Since it is PWM and not DC it's difficult to measure current with a standard meter, it will just show as 5V constant, I used a LED to check for function and polarity.
Note that the USB I used turned out to be reverse polarity, black is + and red is -, be sure to check yours before connecting it to your camera.
The ICS50 itself weighs a gram or two when relieved of it's power wires, the heaviest part of the system is the USB cable.
Do not try to use the lipo version, it won't work.
