Look who's talking.

Finished the thing up today and ran it up to 450ºF with no trouble. Since the chassis is all metal, I tossed the two conductor cord and opted for one with a ground. I was playing around with some of the settings on the PID and it's amazing how well it works for a $20 controller. Once stabilized, it held the set temp within a degree.

I use one of those controllers in my curing oven. Same result +/- one degree, and my heating element is a light bulb!

I used a lot of PID's and PLC's where I used to work and they sure are handy tools. I've been thinking about building a PLC based coffee maker for fun. Something completely automated with lots of user input to vary things like quantities of coffee and water, temperatures, coarseness of grind, etc.. Sort of like a robo-barrister.

You've got way too much time on your hands.

Time? Maybe.
Idle time? Not a chance.
