Inspired by the Irene mote, I thought that it would be really cool to create another mote compatible with the Irene enclosure. 

It's got sensors to measure temperature, humidity, barometric pressure, and ambient light in a wireless mote the size of a key-fob. 

However, as I started to work on the layout, I realized that by segregating the re-usable components from the application specific ones, I could create a template design that could be re-used over and over again.  The hope is that this will save me time/effort/money (of which I have very little) later on when I want to create another mote.  I'll be publishing the schematic / layout for the template mote and the weather sensing mote as soon as I have a chance to rev the layout (It works, but I found a few minor mistakes that are going to send this board to rev 2 before the files go public)
