Where to obtain parts? Answered
So, I pulled this piece from an old back massager and I wish to build something special for a deaf friend. I have a couple more motors from old game controllers that I'll be scavenging too, but I need some more materials for the rest of the device. Anybody know where I can obtain the circuits and other parts to build a music visualizer (not arduino or anything requiring programming)? Preferably free or the very least free?
