Lab Notes
Short notes from the bench: prototypes, debugging, design decisions, and the occasional useful failure.
Lab Note #005 — The Infrabass Appliance
Two car subwoofers, an automotive amplifier, and an ATX power supply meet a perfectly respectable desktop hi-fi.
Read Note →Lab Note #004 — The Bodge Wire That Crossed the Entire Board
A bodge wire saved a board with missing test points. The fix works, the board runs, and it's got more character than before.
Read Note →Lab Note #003 — Simulating Sensors Instead of Chasing Them
Why I built a sensor emulator board instead of waiting on real hardware. The art of testing embedded systems without the actual sensors.
Read Note →Lab Note #002 — Is USB 5V Good Enough?
Why I stopped trusting USB VBUS and added a buck-boost converter. Small decisions that separate prototypes from bench tools.
Read Note →Lab Note #001 — The Board I Built After Frying Too Many Dev Kits
The origin story of DevGuard 24 — an inline protection board born from too many fried dev boards.
