I made a control board for the Microsoft Sculpt wireless keyboard that converts it to wired USB, and now my favorite keyboard is even better.
The QMK config is available at @chadaustin/qmk_firmware ( keyboards/handwired/sculpt/ ), and the PCB design files at @chadaustin/wired-sculpt-pcb .
I’m planning on making at least one more, so if you’d like one, maybe I can help.
