Thanks to all you guys who have been coming forth with help and ideas for my project! The current use for the ADXL is to tell the BasicX when the liftoff of the rocket occurs, so the BasicX can start commanding a 35mm camera to take photos according to a pre-defined pattern. e.g. Wait 5 seconds, take 3 shots 1 second apart, then wait 10 seconds, take 20 shots, etc. So the 2G version is great for this application. But now that I see how easy these things are to work with, I have plans to use the 50G version to sample and store the acceleration for the entire flight. I'm trying to get this gizmo and the rocket finished in time to take them to LDRS in South Carolina July 1-4. LDRS = Large Dangerous Rocket Ships. Check out last year's LDRS at http://www.ldrs99.org/ to see what I like to do in my spare time with my spare money. Wish me luck - I'll let all you gurus know of my successes and failures when I get back, and (I hope) post some pictures of South Carolina from 3000 feet up. Thanks again!

He's using the ADXL (and an altimeter) with a radio telemetry system on his rocket...also has a photo taking setup. http://www.tfs.net/~petek/projects.html Duncan

Thanks, Duncan - that is interesting. Lots more info that I won't have to dig up myself. --- In , orthner@s... wrote: > At 06:51 AM 6/10/00 +0000, Jeff wrote: > > >The current use for the ADXL is to tell the BasicX when the liftoff > >of the rocket occurs, so the BasicX can start commanding a 35mm camera > >to take photos according to a pre-defined pattern. e.g. Wait 5 > >seconds, take 3 shots 1 second apart, then wait 10 seconds, take 20 > >shots, etc. > > > >So the 2G version is great for this application.
