Open-source differential solar thermal controller. ESP32-S3 + ATmega32U4, 4× PT1000 sensing, TRIAC pump control, relay valves, W5500 Ethernet, RS-485, ESPHome. Designed for dual-tank hot water systems.

Source code of web app for the visualization of an optimization methodology applied to a combined cooling system for solar thermal processes within the Spanish national project SOLHYCOOL, from the Plataforma Solar de Almería - CIEMAT.

Architecture-complete green-hydrogen validation repo: safety-gated bench testing, gas verification, carbon/source accounting, BOMs, assembly walkthroughs, Gankyil-A A/B tests, and evidence receipts.

STAG: solar-thermal (not PV) → thermoacoustic resonator → linear alternator. Evaluation-grade architecture, safety, models, and falsification-first tests to measure real power vs measured heat input/losses.
