CodeKi Lab’s split-beat controller and companion tools
A Korean personal lab documenting a Hall-effect split rhythm-game controller, an Android gamepad bridge, and a firmware profile patcher.
- For
- Split-keyboard and gamepad hardware tinkerers
- Worth noticing
- The C86 revision keeps two internal ground layers in a four-layer board; the revised wheel’s real-world fit is still being checked.
Field notes
The controller’s build history tracks PCB revisions from C77 through C86 and explains the tradeoff between layer count, grounding, and signal interference. For its horizontal wheel, the author records a shaft that slipped in the assembled prototype, then documents dimensional changes while explicitly leaving the revised fit unconfirmed. The page also provides installation paths for desktop plugins and MCP, including a note that Claude’s first launch may need internet access to install Python dependencies.
