Heat AND Chill — A Fermentation Brain That Holds One Perfect Temperature
You'll walk away with: A fermentation controller Claude Code built — a Raspberry Pi reading a DS18B20 probe and switching BOTH a heating belt and a fridge through UL/ETL-listed smart plugs to pin your beer, kombucha, or yogurt to one setpoint, with a hysteresis deadband, a compressor anti-short-cycle timer that protects the fridge, and a small web page for the setpoint and a live temperature log.
