Kevin Santo Cappuccio on Mythryl: “This was my super janky setup just to check if it would work at all”

This is just copper pads hooked up directly to gpio, and PIO state machines reading tiny changes in capacitance... without any "real" analog circuitry. (Credit to Matthias Wendel, I stole his pico-femtofarad code and made it into a 3D gesture sensing thing.) github.com/Matthias-Wan...
