A very silly but functional single-key keyboard - perfect for vibe coding! This project combines interesting hardware design choices with AI-assisted firmware development.
- Dual Power Management: Uses TPS2117 for clean switching between battery and USB power with controlled slew rate
- Versatile Switch Compatibility: Custom PCB footprint supports both low-profile and full-height Cherry MX switches
- Stabilizer Support: Full-height keycaps can use stabilizers for improved feel and reduced wobble
- AI-Coded Firmware: The entire codebase was developed through AI collaboration without manual code review
The PCB incorporates several thoughtful design decisions:
- TPS2117 power switch controller enables high capacitance loads without violating USB specifications
- Hybrid Cherry MX footprint accommodates both switch types (though stabilizers only work with full-height switches)
- Clean power management replaces traditional MOSFET/diode circuits
