Claim 9:
10. An electroplating system for non-uniform circular motion system for driving 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;
d. wherein the first nautilus gear includes a first spiral side and a first flat side; the second nautilus gear includes a second spiral side and a second flat side, wherein the first and the second spiral side include a Fibonacci spiral and are identical;
e. wherein the first flat side and the second flat side hit against each other before a next rotation starts, and when the first nautilus gear is moving at a constant speed, the second nautilus gear speeds up and slows down during a course of its rotation based on the Fibonacci spiral of the second spiral side;
f. wherein the electroplating barrel rotates at a first rate during the rotation along the second spiral side and then rotates at a higher second rate once rotating along the second flat side; and
g. wherein a center longitudinal axis of the electroplating barrel is offset from a center rotational axis of the second nautilus gear.
