open spectroscopy / handheld node

luxnode

A handheld spectroscopy node for people measuring plants, fermentation, minerals, and raw spectra. Minimal hardware. Calibrated data. Cloud jobs when local compute is not enough.

lux cloud scaffold

auth, devices, spectra, and analysis jobs are online.

Lux Cloud is wired for Supabase SSR, magic-link auth, protected spectrum records, and queued processing jobs. The first production path is intentionally small: collect clean scans, keep calibration metadata, and hand expensive work to cloud workers when the node should stay light.
