“This build was made to address the problems people (like me) have using high voltage lights by using low powered battery operated LED Christmas lights. It is also intended for just a small setup like a Christmas tree or other small scale display. I also only setup to use 6 music channels and used MOSFETs to switch the lights on and off rather than relays. More or less channels can easily be accommodated with some simple code modifications and a little less or more additional hardware. I also modified the light string wiring somewhat and created a harness using 3.5mm mono audio extension cables to connect the light strings. My build at this stage is still a bit of work in progress, however, it is in a state that I could put it to use right now.”
