Sine Cosine Machine

Another curious device made by aklego, this time it makes projections of the sine and cosine mathematical functions, using gears in epicycloid configuration.

As said in video description:

"This machine is a physical reproduction of a program entitled SineCosine that ships with the computer language "Processing" The program makes four dots oscillate in simple harmonic motion, each pair being 90° out of phase . This machine does the exact same thing. Rotary motion is converted to simple harmonic motion using an epicycloid straight line mechanism."
