One of my favorite things about building keyboards is doing weird and novel stuff.
For example, in a recent keyboard I managed to shove 30 encoders onto the PCB. It’s not useful, but it’s a bit interesting. Other examples: infrared decoding so you can use a remote control, combining a mouse and keyboard into a single device, Hall effect switches for analog inputs, motorized linear potentiometers, solenoids, etc.
I’m looking for more stupid things to shove into a keyboard. Any ideas?
