I got one a few months ago and just started doing baby projects. Here's my first project: http://www.blendedtechnologies.com/realtime-plot-of-arduino-serial-data-using-python/231 http://www.blendedtechnologies.com/realtime-plot-of-arduino-... It's just a knock sensor that prints a plot of the knocks to the screen. a "poor man's oscilliscope" sort of. My next project is a variation on this haptic ultrasonic hat: http://instruct1.cit.cornell.edu/courses/ee476/FinalProjects/s2009/rs423_jsb89/rs423_jsb89/rs423_jsb89_Ultrasonic_Haptic_Vision.html http://instruct1.cit.cornell.edu/courses/ee476/FinalProjects... I'll post it a writeup if anyone's curious.
