I thought that it would be a good fun for my 3 years old son to have something like a box with many knobs and switches making some sounds, but I didn't saw anything like that in shops so I thought I will make one and here it is. The sounds are not random. Every knob corresponds to different effect and you can join all of them for final effect. There are A LOT of possibilities for final sound.
You can always change the way it behaves by connecting it through ISP port with USB programming cable to computer and change the program that runs it.
