IESH v0.1 — Building the Classroom Prototype
From a Raspberry Pi and a breadboard on 20 May to a boxed, working station on 15 June. 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 27 activities — all working with zero internet. Notes from the bench, with the full build-log gallery.
