Pocket etch a sketch12/19/2023 ![]() ![]() Put cardboard under it to avoid damaging the case. The best approach is to get something long and thing (like a metal ruler) underneath and lever it up. On the original and the pocket Etch-A-Sketch these are mounted onto metal drive rods, and can be removed with a little force. The Etch-A-Sketch comes with two white plastic control wheels for drawing with. ![]() The colours are optional, but allow the parts to match the aesthetic of the original Etch-A-Sketch. ![]() The parts are all available to download as a zip of STL files or to tinker with directly on TinkerCAD. Finally, there is a small camera mount which sits on the top of a Raspberry Pi Zero to hold the camera. There are two wheel gears (printed in white, orange in the image below) to replace the control wheels of the Etch-A-Sketch, and two driver gears (printed in red) for the steppers. The first, the largest, is a frame which surrounds the Etch-A-Sketch and holds the stepper motors in place. The total build & print time should be around 1 day allowing for snacks. The camera is mounted in the final 3D printed piece. The wheels are driven by two stepper type motors mounted on the 3D printed frame, through two 3D printed gears. ![]() The control is handled by a Raspberry Pi Zero (or Zero W) and a custom circuit board containing motor drivers and inputs. Glue Hot glue to mount batteries, superglue to mount shutter, (optional) soft glue for camera mount.Įtch-A-Sketch is built from a pocket Etch-A-Sketch and 6 individual 3D printed components.
