Turning Mechanisms I have built using wiper motors (e.g., Snake Charmer, Virus, Sacks Player)
are too big and complicated just to make a head turn (examples below) so I decided to try one
using a small Synchronous Motor.

Note: The weight of the head is supported by the Lazy Susan and a block of wood. The motor is
only used to swing the Lazy Susan back and forth. The back and forth movement is achieved by the
auto reversing feature of the motor.
