This was an awesome little weekend project. It consists of mainly a 556 IC which is really two timer chips stuck together. It pretty much creates square waves. there’s a volume knob on the side that doesn’t seem to be very volumy? Maybe because I stuck two speakers in the box making it 4 ohms instead of one 8 ohm speaker. The knobs on top are for frequency and time between the square wave samples. Fun little toy and a way to kill some time on a Sunday evening. I’ve got a really awsome V-Tech phonics toy from my daughters that I’m working on now too.
