[Build Log · Kathmandu, Nepal] IESH v0.1 — Field-Testing the Classroom Laboratory

The modular v0.1 adds soil temperature and moisture, CO and air-quality proxies on a proper ADC, a fisheye sky camera, and an onboard learning portal with 25+ activities — all working with zero internet. Notes from the bench, with the full build-log gallery.
