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.
