Now its all software, a program was whipped up for OSX which converts low res pictures into squiggly lines perfect for the etch-a-sketch to draw on its screen. The plywood is sent though a laser cutter creating most of the stand and gears. With everything set in place via foam board and paper printouts, it is off to get some thin plywood. Next was a way to attach the steppers to the knobs, gears would be used and a collet meant for model airplanes was sourced to make the mechanical connection between gear and shaft. Next a stand was mocked up using foam board, which helps determine where all the parts should live. An Arduino is used to control a pair of stepper motors which were sourced for pretty cheap, and even came with their own driver. While the idea is not that new, there is always a different way to accomplish a goal. Decided to make a computer controlled etch-a-sketch.
