The Mooftronic Electric Organ measures just 3cm by 1cm and it built around a 24 pin integrated circuit holder. A small stylus is used to play 8 notes in just one octave in the key of C. As well as creating those 8 notes, it has a small antenna which makes crazy noises too when picking up interference from the speaker. To generate noises the miniature organ uses an 08M micro controller built by Picaxe.
One funny thing to note in the pictures below is that the power source to keep this thing running is actually a lot bigger then the miniature organ it’s self. It will probably work with a smaller button cell type battery, but for ease of use I can see why the creator used a 9V battery due to the ability to just clip the connector on the battery. It’s not a bad idea although potentially it could be difficult to play due to the small size.
