HEAT SOURCE: Larry (MSI GT72 Dominator) — the laptop running this incubator plan is also the incubator · GTX 970M · 80–100W sustained waste heat under inference
ARCHITECTURE: Indirect thermal coupling — Larry's rear exhaust vents → copper absorber plate → 3–5L water thermal mass → incubator chamber (air-isolated)
ENCLOSURE: ~$40 Amazon styrofoam incubator (Magicfly/Matestar 9–12 egg), built-in heater as backup only
SENSORS: DS18B20 temp probe ($2) · DHT22 humidity ($3) · Arduino Nano / ESP8266 ($4) · PID thermostat module ($8–12)
INFERENCE DAEMON: Gemma 2B Q4 on loop — Larry's GPU load = heat source · pause if overtemp · resume if undertemp · AI keeps eggs warm
UPS ADVANTAGE: Larry's battery maintains heat during power outages (1–3h) — key differentiator vs. wall-powered incubators
TARGET: 99.5°F ±0.5°F for 72h · 60°F ambient (NE winter worst-case) · total system under $250
SCOPE EXPANSION: Conversion kit design works for any rear-vent gaming laptop 2013–2020 · ≥75W GPU TDP · ≥3GB VRAM · CUDA/ROCm · compatibility checklist included
