Sometimes we miss that old Etch a Sketch we had when we were kids. The challenge of producing a decent image using those two knobs was always fun and frustrating at the same time. This project lets us recreate this interface on our computer. The Hack a Sketch is a combination of an Etch a Sketch style input and a processing sketch to recreate the experience. They’re using an Arduino to interpret the inputs and feed it to the computer via USB. We really like this thing. Simplify the electronics and we could see this as a neat toy for sale somewhere like Thinkgeek.
