Etch-a-sketch + Arduino + laser-cutting = win
It’s called the da Vinci by Patrick McCabe. It’s based around an Etch-a-Sketch, driven by 2 stepper motors controlled by an Arduino.
It’s not the first time I’ve seen someone add electronic control to an Etch-a-Sketch, but I reckon the quality of both the build log and the finished article set this project apart. What’s more, he’s included his laser cutting files so you can even fire up your Personal Factory to make your own!
