Bought a travel click by Braun a few years bact to put next to me when I work. The quality is abysmal, the hour arm is half to a full hour ahead after I used for a while. And it costs like 30 bucks I guess one just pays for the brand name while the product is the same quality as no-name ones on aliexpress for a tenth of the price.
I’m currently working on a personal version of the Mecascape[0] (as much because of the cost as a chance to play with some hardware ideas). Taking it on travels is part of the fun.
I’ve been building a retro computer BASIC operating system for microcontrollers.
My first project is a watch made from an ESP32-S3 with an AMOLED made by Waveshare.
A traveling clock could make a really interesting second project and, because it could plug in, a slightly less challenging one.
