So the way this thing works is it's a series of snap-together blocks. Each block contains a particular bit of electronics, like a transistor or resistor.
When all the pieces are snapped together in the right order, you get some electronic device. In this case it's supposed to be a radio. Unfortunately, it looks like the kit I have is missing some original parts and has some extra parts from an expansion kit. So, I can't make the radio work.
