Abstract:
A transistor circuit including a capacitor charging circuit and an actuator such as an electric motor provides a two part cyclic timing circuit, one part being one complete revolution of the motor and the other part being the charging time of the capacitor. The entire device is designed to run for an extended period on two dry cells. Practically no current is drawn while the motor is at rest contributing to a long battery life.
