This is a little off topic, but I hope that you will forgive me, as a great number of Radio Hams are also into Raspberry Pis as well !
Spent the day working with my son on a number of Raspberry Pi projects, the first we to see if we could get our Raspberry Pi to drive a 16 x 2 LCD.
We followed a very useful How to on the AdaFruit Site
As you can see we set it up with the basic option showing Date / Time / IP Address.
You may have already worked out that this is a model A Raspberry Pi, and has been setup with a Wireless Wifi Dongle, and a Static IP Address.
We did have some initial issues with the Pi Hanging, however these were resolved with a better quality power supply.
The second thing we have been working with is the Raspberry Pi Camera, you can get one for your Pi from http://uk.farnell.com/raspberry-pi/rpi-camera-board/raspberry-pi-camera-board-5mp/dp/2302279
Using the motion software. a good guide that worked for us is at http://www.geeklee.co.uk/working-the-raspberry-pi-camera-raspbian-motion/
