I’m Derek Welty: electrical engineer, systems lead, and increasingly the person in my apartment who wires things together until they behave.
This site is my technical build log. Raspberry Pis, Home Assistant, HDMI capture, small Python tools, local services, automation glue, and the occasional website plumbing. The posts are written after the work, while the sharp edges are still fresh.
The goal is not polished tutorials. It is enough context to rebuild the thing later: what hardware I used, what commands mattered, what failed, what logs explained the failure, and what I would change next time.
