I finally got around to writing up my first Arduino project.

http://fischco.squarespace.com/blog/2009/3/17/arduino-rangefinder.html

Its an ultrasonic rangefinder that is positioned above my desk at work.  I've got some buttons to adjust the detection range.  When it detects a state change, ie "Here" or "Away", it sends a signal to a simple Processing app, which in turn hits a web service and logs me as at my desk, or away from it.  Then people can visit a web page to see if I'm there or not!

Not terribly useful, but it was fun. smiley
