How to Make a Raspberry Pi Powered Etch-a-Sketch System
The Etch-A-Sketch was released by The Ohio Art Company in 1960.
The popularity of the device is sort of interesting because it has lots of annoying problems:
- knobs only move the cursor up/down/left/right. Diagonals and curves require a steady precision that most children 3+ simply don’t have.
- you can’t draw two objects that are not connected.
- No ability to undo small mistakes. If you want to undo something you’ll have to redo your whole masterpiece.
This Raspberry Pi powered Etch-a-Sketch is a sort of high definition game: it is capable of drawing almost anything you can think of and upload. It allows the retro drawing device to draw images sent to the pine mini PC.
The required hardware is:
- Raspberry Pi
- Etch a Sketch
- 1x Piece of Wood
- 2x Stepper Motor
- 2x Shaft Coupler
- 8x Jumper Cables
As the maker writes on its website, his plan is to write a program that uses some motors to draw nice pictures on an etch-a-sketch.
For the reasons above, recreating pictures by hand is tedious and extremely difficult. My hope was to get to a point where my program could draw things better than I could. I’ve always wanted to learn more about how to use hardware with python so I was pretty excited to start this one.
