Drone Jar (Rucci, Handmade Optical Synthesizer)

Built inside a jar, this drone synthesizer consists of three square-wave oscillators modulating against each other. The pitch of each is controlled by outside light sources hitting the three sensors inside, so there is a lot of room for experimenting. Reacts well in dark settings with light sources such as flash lights, fire, video monitors, the sun etc.

There is a single switch on top for power which is supplied by an included 9-volt battery. A red LED indicates power and a 1/4" output jack makes it easy to connect to amps, effects, or recording equipment. It measures roughly 2.5" wide by 3.5" tall.
