Let's get started.
You will need:
A Raspberry Pi computer, I tested with the 512 MB model, with internet connection.
An SD card loaded with the latest Raspbian “wheezy” software. See http://www.raspberrypi.org/downloads
for how to get that setup.
A supported bluetooth USB dongle. See http://elinux.org/RPi_VerifiedPeripherals#USB_Bluetooth_adapters
Some way to access a terminal on the Pi. I used ssh, or just use the normal desktop and open Terminal.
