Make: Projects – Water Bath Thermostat
This project was inspired by “Cooking for Geeks” author Jeff Potter’s quick DIY sous-vide hack. My plan, initially, was to just hack the controller into an enclosure with an A/C outlet, the idea being that you could just plug any heater you wanted into the outlet. Looking around for cheap temperature controllers, however, I happened across the STC-1000 on eBay for $25. It’s not PID, but it has proven to be plenty accurate enough for almost any practical purpose. And since the STC-1000 has both heating and cooling functions built-in, the logical next step seemed to be to split a single A/C outlet so that you could plug a heater or a cooler (or both) into it and use it for all kinds of stuff.
