Circuit-bending is tons of fun. The basic idea is that you take parts of any old electronic device, say a cheap toy keyboard, and probe all around with wires and resistors, disturbing its normal funct...

Want something that you’ll try for fifteen minutes before realizing it’s extremely stupid and has limited utility before throwing it in the back of a closet to eventually sell at a yard…
