Educational electronics trainer: auto-generated schematics and 3D PCB views where you find an injected fault using a simulated multimeter, backed by real KiCad imports and ngspice simulation.
See CLAUDE.md for architecture and conventions.
Requires ngspice on PATH (sudo apt-get install ngspice) and kicad for kicad-cli (sudo apt-get install kicad).
map.json and faults.json under each devices//` are generated, not committed (see CLAUDE.md) — after a fresh checkout, regenerate them once per device:
