Built with AI, to drive AI.

A handheld Bluetooth macro pad — CAD, firmware, electronics, and a v1→v2 iteration loop. None of them their trade.

01

Parametric CAD

One continuous-solid 130 mm housing built in code; a captive print-in-place switch cap; FDM limits codified.

02

Embedded firmware

ZMK on an nRF52840 — 5 keys become 10 actions via tap-vs-hold, plus combos and a Claude-launch macro.

Engineering rigor

A field-log of H/K/P issues where daily v1 use generated the v2 spec: v0.1 → v0.9 → v1 → v2.
