Teka-Sketch
By Andrew Gregory. Posted
The Etch-a-Sketch was, for this author at least, impossibly difficult, frustrating, and not fun at all. In other, more artistically gifted hands, its constraints lead to brilliant artworks, but for us, the Etch-a-Sketch was an instrument of torture.

Head to head: Raspberry Pi + Raspberry Pi Zero + Raspberry Pi Pico.
Maker Tekavou has taken the Etch-a-Sketch and made it better, by not making it an Etch-a-Sketch at all – his version uses an e-ink screen, rather than the original grey powdered aluminium which gets scraped off to reveal the black underneath. He’s also developed a way of turning photographs into Etch-a-Sketch-like images, and has built a Raspberry Pi Zero 2 W-based camera to take images and upload them to the new and improved Teka-Sketch. It takes 10–15 minutes to render an image on the Teka-Sketch when the conversion is performed on the Raspberry Pi Zero 2 W; to speed this process up, the maker has added a Mac mini in between the camera and the display, to perform the work of turning the image from a photograph into a realistic Etch-a-Sketch image.
