The travel board is finished. It’s not likely to become a daily driver, but it is fit for its intended use case. The half-height black switches are smooth and put up enough resistance that I don’t hate using them (though they are not converting me either). It’s quieter than anything else I have, fairly light, and it’s barely an inch thick, including keycaps and bumpons. It will be perfect for plopping down in a suitcase or backpack. The MCU didn’t like the latest version of CircuitPython, which I did not figure out right away, leading to a rather yucky looking solder job on a couple of the pins, but it all came together well using POG/KMK again. No 3D printing at all on this one, it’s all laser cut Masonite, maybe a dollar’s worth of raw materials for standoffs and the plates.
The Sinclair inspired keycaps are kinda variable in their intensity, same as the other set I did on white PBT blanks from Aliexpress, but they make me smile.
