Bimetallic strip thermostat in my parts dryer shit the bed, so decided to upgrade it. Leave a comment

This used to be a food dehydrator, now it’s a parts dryer full of reusable desiccant. Contacts melted out of the strip that turned a 1200 watt halogen bulb on and off. A bit of re-wiring and an Amazon purchase later, now I have pretty temps thanks to a thermocouple, a solid state relay, and a PID controller all crammed into a little project box.
