Why thank you.
If I ever do get down that way, I will take you up on that offer.
Tonight I will move the sensor up and forward then wait a few days and check temps again. Overall I think it was just a bad idea putting that sensor in the lowest corner, next to the coldplate, and stuffed behind a fullsize keg. I think moving it will drop it the few degrees I want.
And don't worry about the resistor suggestion, the pack i bought came with a 33k, so everything is A-OK.
Cheers
PS: I love any chance I get to solder something!
