riskable
non-flat keyboard?
I use an ergo keyboard, the Kinesis Essential. It has two flat mini-keyboards (ctrl/alt/backspace/delete/home/end) and (alt/ctrl/space/enter/pageup/pagedown), and two dished keyboards. Frankly, dishing and PCBs are incompatible .... until now! If you print the key retainers in a dish shape, and use through-hole 49E hall sensors, you can vary the length of the leads so they are different heights above the PCB to match the dishing of the key retainers.
I'll try it and let you know how it goes.
I just found out about void switches and am currently using an ergo kb myself. Any updates on this project?
The above is one of my many projects, which one of which has made little progress beyond printing a base and printing the keys.
