Solar Sound Bowl, Experiment
This is a plastic salad bowl, hanging on a nail, with a solar charging circuit attached. When the light charges it to around 1.5 volts, the energy is released into a dangling motor with an eccentric cam attached to the shaft. The motor and cam then bounces off the plastic and creates a tapping sound. It is my hope to soon install 20 of these into a space to hear the sound they create and the patterns of sound created with the changing sun reactions.
