Roomba 620 infrared signals
Having been pondering it for a while, I recently bought an iRobot Roomba vacuum cleaner - the Roomba 620 which is the current entry model. For fun I took some photos with an infrared sensitive webcam (a trusty XBox Live Vision), and then measured some of the IR signal codes with my Raspberry Pi.

Raspberry Pi XBMC infrared remote control
I've added an infrared receiver to my Raspberry Pi, tucked inside a PiBow case with its clear top layer letting it receive the signals. This lets me re-use an old DVD player IR remote to control XBMC running on the Pi.
Basically I followed this AdaFruit Tutorial for adding an IR receiver to the Raspberry Pi, but not being in the USA I had to substitute parts which I sourced via eBay instead. Despite much searching, the shortest suitable jumper cables I could find (one pin to one pin, 1P-1P, and female-to-female, F/F) were 10cm long - which is a bit much to coil up inside the Pibow case but easier than soldering.
