Reddit user CertifiedWerewolf (aka Ryan) wanted a distraction-free, light, portable typewriter – something very like the Freewrite Traveler, in fact, but without the £483 price tag. So, he put together a Raspberry Pi Zero 2 W, a Waveshare 4.2-inch e-paper display, a PiSugar 3 battery and a custom-made 3D-printed case, and a keyboard he already had, and made his own for a princely $90.

We love how simple this build is: the clean lines, the minimalist design, and the ethos of doing one thing and one thing well. The fact that it’s homemade, and Ryan has shared the code for it on GitHub, makes it even better.
