My 2nd Arduino, an ExtenderShield, an Innovations ID-12 RFID Reader, a custom shield, a Lithium Backpack, and two Xbee breakout boards are making their way to my house from Liquidware and Sparkfun. I already got my two teeny-tiny Xbee's, and they look so awesome. I also have to go get a soldering iron from the 'Shack (radio, that is), and some servos from a local hobby shop.
ARDUINO IS AWESOME.
