The Tempest is a 36-key wireless ergo split keyboard with some splay, designed by Oliver Thurley (aka thrly/Background_Reporter9).

Really like my corne, but wanted a little splay and more thumb reach. There's loads of excellent alternative designs out there, but I wanted my own and had a lot of fun designing/building this myself! – Oliver.

  • 36 keys (5x3+3)
  • low-profile Choc V1 switches, hotswappable
  • pinky and ring column splay

  • reversible PCB
  • 3D printable case
  • ZMK

Despite the footprint for it, there is no working display on the current version (1.1). The display header pins are not connected correctly. You could probably hand-wire the holes to the microcontroller pins to fix though.
