Gumstix Overo Fire on a rocket

Few weeks ago I was told about an opportunity to fly something small on an amateur rocket in October, when the guys from Danish Space Challenge will launch a bunch of rockets. I figured it was a good excuse to resume my work with the Gumstix Overo embedded conputer that I have lying around.
