I just got my RPi rev.2 with 512M and the sockets CSI amd DSI. I live in the Imperial, 63052 zip in Jefferson County. Please let me know if you organize a users group.
I am using the USB port in the back of my LED tv with a retractable micro USB cable from Radio Shack for power; a Logitech K400 wireless keyboard/touchpad for input; a Netgear WG111v2 wireless USB adapter; the HDMI port to my Dynex 15", 720p, LED-LCD tv. I'm still looking for my powered USB hub that I misplaced.
The only thing I had to buy besides the RPi was the micro USB cabel and the HDMI cable.
After I get familiar with the RPi I will be concentrating on interfacing it with the Arduino and XBee.
Hope to hear from you soon,
Beware of zealots and prophets!
