Hand-wired Split Keyboard
A hand-wired split keyboard featuring Kailh Box switches, custom diode matrices, and Arduino Pro Micro controllers running custom QMK firmware.
The Challenge
Developing high-reliability interfaces and hardware diagnostics for Hand-wired Split Keyboard presented specific boundary challenges. System deployment required debugging logic errors, state collisions, and handling restrictive client specifications.
Primary Obstacle: Diagnosing a solder bridge on the row 3 matrix trace without a schematic.
System Implementation
An ergonomic split layout soldered from scratch, with microcontrollers configured to drive custom keymaps and macros.
Learnings & Engineering Telemetry
[01 // CORE CONSTRAINT]
Diagnosing a solder bridge on the row 3 matrix trace without a schematic.
[02 // POST-MORTEM TAKEAWAYS]
Through rigorous iteration, key system diagnostics were deployed to prevent bounces, optimize memory buffers, and guarantee consistent telemetry packets. Building this architecture enhanced understanding of complex low-level interrupts, firmware bindings, and real-time interface structures.
System Results
SUCCESS: Used a digital multimeter in continuity mode to isolate and desolder the bridged connection.
