I am looking to take the chip from the Arduino and pop it into a custom setup that I create. I figure that if I'm going to go, I might as well go all out. Buying a shield seems to be cheating. Finding out what it takes to put together an embedded solution that I can swap out with the toaster oven's circuit board I am sure will teach me a lot, and be a hell of a lot more interesting than plugging together two things that "just work". There is a .ide on github.
