 Use a circuit board coil to measure how far the key is pressed by measuring the inductance of the underlying coil. This should work because the Cherry MX has a metal spring inside. Also, it has been done before but without good documentation.

 +I tried using a milled single-sided circuit board and a simple circuit by electronoobs for measuring the inductance of the milled coils. Didn't work tho. But I learned some stuff about PCB coils and especially single-sided coils.

- +Here I tried designing a new circuit for the milled coils. I didn't even bother trying it out because it seems too complicated. But therefore I got into circuit-design.
