Cycloid-O-Matic creates spirograph-like patterns

If you’ve been waiting for a new way to generate geometric art, then be sure to check out the Cycloid-O-Matic from InventorArtist Darcy Whyte.

This three-axis cycloid drawing machine is something of an update on the classic spirograph toy, but instead of (only) using an arrangement of gears, it incorporates stepper motors to create smooth curving patterns.

Control is accomplished via an Arduino Uno and GRBL shield, while a single motor rotates the paper in a circle on top of a lazy Susan. A pen is held above in a linkage system, actuated by two steppers that spin to move the linkages and draw in the X/Y plane.
