BauerNet is a home status and security project I am working on with several Freeduino's and miscellaneous sensors. It consists of several nodes that are connected through an I2C interface, although, that is slated to be replaced with a 2.4 GHz wireless interface soon.
This project is really still in the planning phase, although I am in need of organizing some things, so I thought I would just go ahead and get the project page setup now so I can keep all my notes and tables somewhere.
