In my block diagram I'm using the metaphor of different "brains" to identify different subsystems of the Tamaduino. The human brain has parts that are older and more basic, like the brain stem and the cerebellum, and parts that are more recent and complex, such as the frontal lobes.
Looking at my diagram here, I'd have to say that the "Energy Brain" is the place to start this project. The biological analog of the Energy Brain would be the brain stem. It is responsible for the basic metabolic processes of the host. I'll be publishing a rough draft of the Tamaduino's energy system sometime soon. It's gonna be weird.
