The work
Hardware, fabrication, code, and security work — active builds first, then shipped projects, newest year first in each group. Budget-honest, every one.
A working BC250 desktop and animated ESP32-P4 resource display, with a custom case ready for its first fabrication run. About $375 spent so far; the one-off sheet-metal part is estimated at $275.

A handheld board that sweeps the sub-GHz bands and logs anything it hears. PortaPack-adjacent, built from parts that cost less than dinner.
Case study ⟶
Printed Darthbarney's eero mount and designed custom wall mounts for two UniFi Flex Mini 2.5G switches. Parts printed, delivered, and mounted.
Case study ⟶
Seven hard drives, one of them out of a desktop that burned up, no account passwords and no backup. 161,069 files and 492.9 GB read back off them, byte-verified.
Case study ⟶A welded 12U rack with noise-dampened airflow that runs cool and silent in a bedroom. Full cut list and CAD published.
Case study ⟶An open-source bench jig that holds awkward boards steady. Printable on any FDM machine, no proprietary parts.
Case study ⟶A scoped, consent-first reconnaissance toolkit for authorized engagements. Loud about boundaries, quiet on the wire.
Case study ⟶A sub-$30 robotics kit for classrooms. Hundreds built. The project that proved good engineering doesn't need a big budget.
