Abstract
A light powered chime for indoor use specifically designed to be random, approximating a windchime. In one embodiment a solar cell provides current to a timing circuit and to a storage capacitor. The timing circuit intermittently fires a silicon controlled rectifier causing current to flow from the capacitor through a motor. A striker is connected to the motor shaft by way of a string and clip. Rotation of the motor causes the striker to contact one or more suspended chimes. Randomness is achieved by virtue of sunlight variability and by the mechanical and electrical design.
