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. [[https:// | Use a circuit board coil to measure how far the key is pressed by measuring the inductance of the underlying coil.

+ | 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. | ||

+ | This has the first useable results! I made my first PCB and programmed an Arduino library. Seems very promising to me and I can feel I´m on the right track. | ||
