How's it work?

Through the wonders of physical computing! At the core of the device lies a Parallax BS2- plugged into this BS2 are numerous sensor modules (both official & homebrewed) that toil endlessly to gather data. The device has numerous buttons, bells, lights & whistles for user input/output and it connects to a PC via a modified serial cable. Python is used as an interface between the device and the PC and a rechargeable power pack keeps the whole thing going.
