Field-notebook of homemade circuits, PCB layouts, and first-pass schematics. A record of things that worked and things that smoked.
Not a product — a log. Every circuit I've built since 2024 lives here: schematic, layout, notes on what failed, and what I'd change. The 36-key keyboard is the current chapter.
A split 36-key keyboard around an RP2040, hand-wired on a custom PCB. Low-profile Choc v2 switches, QMK firmware, wireless half still in progress. The case is designed in FreeCAD and will be milled from aluminium.
Hardware has no undo. Every mistake is physical and costs real time. That constraint forces a clarity of thought that software sometimes lets you skip — you can't ship a schematic and patch it later.
