used/old circulator... soon to be optimus prime!

I bought this used immersion circulator from Ebay...  it's analog, cheap, and I it works! 
well, kind of...  I need a thermometer in there to make sure it's constant and adjust the thermostat to make sure it's the temperature we need.  Tomorrow it's going to be constructed into a massive unobtrusive master...  well at least for two days until it fizzles and breaks into pieces...
