Beagle or Rasberry Pi

[Daniel Farrar]

The pi has analogue and digital GPIO pins.  I've used it with digital temperature sensors, trigger a 5v relay, LED, button / contact closure, etc.  My programs were in Python, it was really easy to get off the ground.  I used the Raspbian image mostly, but also have one set up as an XBMC media streaming device.

One fun project I made was a remote office equipment rebooter.  It had a list of IP addresses to ping and if it lost connectivity to all internet IPs but not the local network IPs it rebooted the modem using a PowerSwitch Tail II.
