That is some sophisticated smoker control.. :-) Seems to me that the hard part is getting the thermocouple inputs into the PC without going bankrupt.
Did you see this ?? http://www.circuitcellar.com/library/print/0503/moyer154/3.htm Perhaps something like this but instead tied an Arduino or a Pokeys which is then tied to your PC via USB?
