This is actually an upgrade to an existing product, to become "The all-new product" if you know what I mean ;) Plus I have a few other ideas for this type of controller.

I think a resolution of about 25 degrees would acceptable, but if I get a finer resolution that would be ok too. Not a super accurate type of project.

Thanks so far, I'll check out the devices mentioned by you and Bruce.

I'm still kind of hung on what to do with the input to the ADC. I thought maybe I should amplify the thermocouple signal by a gain of 100+ or stay with a low signal level. I've read alot about errors here and errors there and that temperature is quite difficult to measure. Noise considerations and voltage isolation, I'm in over my head, but forge ahead.
