Peter J. A. Cock (aka peterjc/astrobeano) shared his monoblock Slump52, an ergo keyboard with quantity pad, utilizing graph concept to realize the diodeless design whereas avoiding ghosting with 4KRO.
Up till now, I’ve had three totally different keyboard PCBs fabricated to my very own design – all diode-free utilizing Graph Principle. The Gamma Omega TC36K, the Gamma Omega Hesse, and the Forager Acid, with 36, 36 and 34 keys respectively. They have been getting smaller. Nicely now for one thing larger, requested by our 9 12 months outdated: They need a keyboard with extra keys, and deserve smaller keys. Right here is the Slump52! – Peter.
Options
- 52 keys (arrows and numpad)
- low-pro Choc switches, hot-swappable
- CFX spacing (17×17 mm), CFX keycaps
- Raspberry Pi Pico controller
- designed through Ergogen and KiCad
- case created programmatically through Ergogen, build123d
- firmware: each ZMK and QMK/Vial
The location of the Raspberry Pi Pico controller backside left at an angle is to attenuate the keyboard width (placing it centrally like in my earlier Gamma Omega TC36K PCB would add want about 2 cm between the halves).
