Jonathan, I'm so new at this kind of stuff you might have to beat me over the head till I understand :)
Ok the Arduino Uno and a couple of Max6675's . Would I need a mini breadboard and some jumpers to test out with? Hmm, and some kind of board for the Max6675's http://www.sparkfun.com/products/8801 http://www.sparkfun.com/products/8431 I'm reading up on bit banging now.
