In this first functional full build of a rubber Dometyl magnets are attached to the bottom of Niz stems, and brought down over omnipolar (non-linear) Hall effect sensors directly wired to a Teensy 2.0.
This arrangement was chosen for the first build as it does not require any custom scanning / matrix code in QMK. When I foray into my second build, I will probably put in the work to figure out the multiplexing and custom scanning required to use linear sensors with configurable thresholds – Beheddard.
Switches:
Niz EC housings / stems
DES BKE domes. Tiffany on the pinkies, purple on the rest.
