Ingenious DIY Etch-A-Sketch digital camera

Etch-A-Snap — A Raspberry Pi powered Etch-A-Sketch Camera


Martin Fitzpatrick built the Etch-A-Snap, a digital camera with an automated Pocket Etch-A-Sketch as its display on the back. Each photo takes between 15 minutes to one hour to be sketched. From Two Bit Arcade:

Photos are processed down to 240×144 pixel 1-bit (black & white) line drawings using Pillow and OpenCV and then translated into plotter commands by building a network graph representation with networkx. The Etch-A-Sketch wheels are driven by two 5V stepper motors mounted into a custom 3D printed frame. The Etch-A-Snap is entirely portable and powered by 4xAA batteries & 3×18650 LiPo cells.
