1. An electroplating system for non-uniform circular motion of an electroplating barrel, comprising:
a. a motor coupled to the electroplating barrel and to an electrical circuit that provides electrical energy to the motor;
b. the motor operably coupled to a first gear, the first gear rotatably drives a second gear; and
c. the second gear engaged with a first nautilus gear and the first nautilus gear rotatably coupled with a second nautilus gear; the second nautilus gear operably coupled with the electroplating barrel, such that a rotation of the second nautilus gear rotates the electroplating barrel in a non-uniform circular motion.
