Want to become a "beet-boxing" DJ in a weekend, this might be a good read for you.
People conduct electric charges, and so do vegetables. This simple fact spurred designer Scott Garner to build the Beet Box: a machine that plays drum-kit sounds at the tap of a beet. The beets conduct body capacitance, or the electrical energy stored inside humans, to a sensor plugged into a Raspberry Pi mini-computer . Each touch triggers software to produce one of six percussion sounds. Garner hid the electronics inside a wooden enclosure with a lid so that striking the beets emits clashes and snares as if by magic.
