So far my best experiance is with a 80's tape deck/radio. But I broke one of the main rules if you want to call them that, I bent something that plugs into a wall. anyhow, I get rad sounds out of it like strange pulses, screeches, beeps, static. sadly its very limited. so I want to add some simple boards from childrens toys. I don't suggest playing with things that plugs into a wall unless you know what you are doing or you really don't mind a good shock or even a hospital.
