" summary

Builds a DIY sous‑vide around a Raspberry Pi using a soldered thermistor plus an ADC, reads analog values via a V8 add-on in Node, and switches a budget immersion heater (bought for 199) with a solid state relay. Implements a classic PID controller (noted as from the 1890s) tuned by trial and error to stop oscillation, shows heater duty‑cycle reduction and a stable temperature trace, and demonstrates the whole system actually cooking food.
