Good day all.
In my quest to put together a cheap PID controller for my smoker, I put together an Alpha version that worked on AC and was ugly as hell. Alpha prototype; make it work. Beta prototype; make it small.
Here are pics of my Beta prototype unit with mounted interface board.
All you need is a 12V wall wart, a BBQ guru fan, and a thermocouple or PT-100 sensor and you are set.
Regulates temperature to 0.1 degrees.
PID controller in action using magnetic cell phone mount:
Controller, interface board and PT-100 sensor: $20
