Raspberry Pi

I got a raspberry pi a while back. Installed it at home. Running Raspian Wheezy at the moment. It is running Apache, php and some other suites. It is logging to the cloud at logentries.com . I bought a small robot arm kit at the Science Gallery and assembled that; hooked it up to the Pi after buffering the GPIO outputs through some L298H bridge ICs. Then I created a php page whereby you can view the on-board camera images and control the 5 motors and 2 lights of the robot arm. This is a quick snapshot as it sits on the desk:

I set up a cronjobbed perl script to capture the cpu load and cpu temperature, piping them to Xively (previously pachube). This lends itself to some nicely embeddable graphs:
