Ergonomic, split and other weird keyboards
Rules
Keep it ergo
Posts must be of/about keyboards that have a clear delineation between the left and right halves of the keyboard, column stagger, or both. This includes one-handed (one half doesn't exist, what clearer delineation is that!?)
i.e. no regular non-split¹ row-stagger and no non-split¹ ortholinear²
¹ split meaning a separation of the halves, whether fixed in place or entirely separate, both are fine.
² ortholinear meaning keys layed out in a grid

For this you need an analogue sensing mechanism such as hall-effect sensors (as Wooting use). You can see some open-source reference designs for PCBs, Firmware, and switches using hall-effect sensors on riskable's github to get you started. Technically you should be able to make a PCB like this and then use the same "switches" that Wooting use, though idk where they source them.
I think the dometyl keyboard (https://github.com/geoffder/dometyl-keyboard) was designed to use hall effect sensors with wiz switches. Not sure what is the PCB design that read the hall effect sensors.
If we just need digital, a comparator should be enough. However, wooting require 1 ADC for each switch, or at least some multiplexer. As it is unlikely for a single MCU to have that many ADCs, the pcb will likely require multiple chips like ADC0809 that can read 8 different analog outputs. Probably some more mux as well to reduce the number of pins required for the MCU.
