From the project

Symmetrical Hall effect Alice keyboard based off of the Doe

Symmetrical Hall effect Alice keyboard based off of the Doe — split into three boards linked by ribbon cable.

GPLv3. Derived from FN40HE; see NOTICE.md for what is taken and from where. The layout is a reconstruction of the DOE 60% by hare works, measured from published photographs — not affiliated with that project.

The GitHub-facing designs/ index groups the project by connection system and physical layout while keeping one canonical copy of every large CAD and fabrication file:
