CNC Etch A Sketch

This article was originally published as part of HackSpace magazine, which has since been incorporated into Raspberry Pi Official Magazine.
Quint, an engineer from Orgegon, has managed to create a video effect on an Etch A Sketch using stop motion animation. “I got a video of a cat walking in front of a wall and grabbed screen shots I could trace in Fusion 360,” says Quint. The images were then converted into the machine language, G-code, so it could be drawn automatically on the Etch a Sketch. “It took a few iterations but I'm really happy with the result.”
It uses a Raspberry Pi running b-CNC. This controls 2 stepper motors connected to pulleys which turns the Etch A Sketch knobs.
