Beside the ArtPad, Ming-Gih Lam aka dcpedit also published the well-documented Mod Mmm, a PCB designed to replace all internal components of an IBM Model M keyboard. You keep the curved steel backplate, mount this PCB, and get a versatile MX-compatible Model M. Brilliant or pure evil? Genius or heresy? You tell me.

Features

  • Hotswap PCB for MX switches
  • Multiple layout support, including ISO, split spacebar, and 4x5 numpad.
  • Supports up to 3 rotary encoders
  • Piezo buzzer
  • Solenoid
  • USB-C support via STM32F411 Blackpill.
  • Vial firmware
