Oct 3, 2010 - Danish Space Challenge (DSC) held a Rocket Festival at Borris Sønderland, Denmark, where five rockets built by German and Danish students were launched together with one of DSC's own rockets. For the first time, the DSC rocket was flying an Arduino Duemilanove based flight computer which was responsible for releasing the parachute (worked). The payload in the rocket consisted of a digital video recorder built by yours truly, based on the Gumstix Overo Fire embedded Linux computer with an OMAP3530 application processor from Texas Instruments (also used on the open source BeagleBoard computer).

During the descent, the rocket got separated from the parachute and crash landed. Although the Arduino board and the Gumstix Overo Fire (mounted on a Tobi expansion board) looked surprisingly well, the microSD card where the onboard video was stored fell out and got lost either during the crash or during the recovery. Considering all the tape we used for the wires, we could have used a piece to secure the microSD card to the socket :o)

The long term goal is to have the hardware DSP in the OMAP3530 perform hardware accelerated encoding of the video for real time downlink. We hope to have that ready for the next rocket festival that will take place during the spring 2011.
