Home projects that go beyond “installed it” or “fixed it.” I look at how the system works, measure what I can, and use calculations when they help — from roof ventilation and HVAC to repairs and small home automations.
A tiny slider adjustment restored a metal zipper. I checked YKK's explanation, measured the chain at about 5 mm, and mapped out the replacement path if it returns.
Read more →Custom domain, GitHub, Cloudflare Pages, Before→After, and a Preview workflow — with the initial build and first launch completed entirely from an iPhone.
Read more →How much attic air can move using only eave intake and ridge exhaust? I estimate airflow and heat-removal potential from wind pressure, temperature difference, and vent area.
Read more →Lighting, sensors, small mechanisms, and other practical home experiments.
Coming soonProduct specifications, real measurements, calculations, assumptions, and the things that did not work. I try to keep measured values, estimates, and inference separate, with references when outside sources support a technical claim.
