Splitflap

Split-flap is an integrated system of software and hardware specifications for driving mechanical split-flap displays. It provides a split-flap display controller and distributed hardware drivers to manage the rotation of mechanical flap modules using stepper motors and microcontrollers.

The project includes a vector flap artwork generator for creating printable SVG design files for custom characters and fonts. It also features tools for laser-cut panel design to produce hardware components and combined module faceplates.

The system covers distributed hardware control via a daisy-chain controller topology and stepper motor motion control using acceleration ramps. It includes hardware device calibration through sensor-based home positioning and hardware health monitoring using loopback error checking.

    This repository is a public collection of production-grade hardware design files for Keychron keyboards and mice. For keyboards it includes case, plate, circuit board and full-model files, covering over a hundred models. For mice it includes shell, low-friction foot, receiver and full-model files. Everything is organized into folders by product series, so the files for a specific device are easy to locate. The designs are published in neutral exchange formats (STEP, DXF, DWG and PDF), so they open in standard CAD tools without proprietary software. A format guide is included for compatibility
