Published a few months ago, the JK206 by Jhonatan Ferrer aka Jhoalferco has now a nice stacked acrylic case (not yet in the repo).
Some time ago I designed and assembled the JK206 keyboard, and I was quite happy with the result but it looked a bit fragile, so I designed a new case with gasket mount using stacked acrylic – Jhonatan.
This project consists of a mechanical ortholinear keyboard design that is capable of being used as a macropad/numpad or a 50% keyboard.
This is achieved through the modular design of the PCB that can be used by itself to mount a macropad with up to 20 keys (5 of them can be exchanged for encoders), while with three PCBs you can build a keyboard with up to 60 keys (3 of them can be encoders).
