EtchABot turns your Etch A Sketch into a CNC (Computer Numerical Control) drawing machine. I’m really excited about this project because of its versatility and its well balanced combination of entertaining and educational aspects. It’s always fun to hack a toy to do something above and beyond its original intent, and if you build the EtchABot and run the example Arduino sketches, you can make:
- A self-erasing Spirograph
- An analog clock
- A joystick-controlled doodling machine
- A web browser-controlled drawing robot to reproduce free-hand, raster or SVG digital images.
There is an EtchABot Arduino library, so it’s also easy to program it with your own ideas.
