This adjustable-agle monoblock split keyboard, the ortholinear Protractor, was designed and shared by BFB_Workshop, creator of the Compaq'ed ortho replacement PCB for the Cherry G80-11800. While this current project is handwired, the main idea is the 3D-printed hinge mechanism and custom keycaps, both of which are freely available.
Here is my first take on a portable low-profile keyboard. Unlike my previous daily driver, it is flat enough for the table to serve as your palmrest. I've designed the hinge to provide some level of adjustment – BFB.
The keyboard is compatible with regular keycaps (2-layer case). However, it comes with a custom 3D-printed set of low-profile keycaps that allow for a more rigid 3-layer case while maintaining the overall height.
Specs
- 60 keys (6x5 ortho layout)
- Gateron KS-33 switches
- Nice Nano v2
- 3D-printed case and keycaps
