Small write-ups on home electronics, soldering and the occasional hike.

The power supply hummed, so I swapped the two main filter caps. Took an evening, worth it.

Cheap thermometer, honest readings?

Compared three budget sensors against a reference probe for a week. Results were surprisingly close.

Two days in the hills

Light pack, one stove, too many photos. Notes on what I would leave at home next time.
