I hate it when a keyboard project has no name – how are people supposed to reference it? Anyway, this semi-parametric split with keywell, designed by Gregory Zhizhilkin aka stopdesign, is documented on his blog at grrr.sh, so let's call this the Grrr keyboard.
I made a compact ergonomic split keyboard, designed to reduce desk footprint and minimize wrist strain – stopdesign.
Inspired by the Dactyl and Corne, the structure consists of a flat base platform and a curved plate, connected by organic-looking legs.
Features
- 36-38 keys (6x3+3-4 thumb keys)
- MX, hotswap
- handwired
- WaveShare RP2040 MCU
- parametric model
- optional encoder
The model is somewhat parametric. You can adjust certain angles and distances.
