YarmanKB's Herman Berdnikov (aka SpeedRa1n/jayadamsmorgan) shared the YKB Skadi – an open-source Hall-effect ergo split keyboard. It's wireless, and features a nice keywell via the Dactyl-inspired case.
This is not a gaming keyboard, but a typing tool and a platform for experimenting with what Hall Effect keyboards and a keyboard firmware can actually do – SpeedRa1n.
Custom translucent keycaps from fkcaps.com, custom firmware. The bendable PCBs for the columns, featuring addressable RGB LEDs and Hall-effect sensors, are connected to a central unit.
Specs
- 60 keys (6x4+6 columnar split)
- magnetic switches, inherently hotswappable
- custom XDA keycaps from fkcaps.com
- Holyiot-21069 controller (nRF5340 module)
- TMAG5253 sensors
- per-key RGB LEDs
- 3D-printed case
- ykb-firmware (custom)
Like ZMK, the firware also uses Zephyr, so it should support any Nordic based magnetic keyboards by adding board files.
