This page describes experiments carried out to create an embedded video processing unit based on the OMAP3530 application processor from Texas Instruments using Gumstix Overo COMs. This is one branch of the Embedded Video Processing and Radio Unit project. Logbook is on the talk page.
- Capture video from one or more cameras
- Compress and multiplex the videos with telemetry into a single transport stream suitable for transmission over the air
- Process incoming telcommands
First flight on amateur rocket
The objectives of this flight are:
- To test the Gumstix Overo Fire under high acceleration (TBD g)
- To capture images and/or video during the flight
We learned about an opportunity to fly onboard an amateur rocket (up to 3 km high). Flight will take place on October 3, 2010. Time is very short so we will be focusing on getting the Gumstix Overo Fire up and running, and have it record video during the flight. No real time video downlink.
OS version: Angstrom 2010.7-test-20100909
