Hi everyone,
I have been playing a lot with arduino accelerometers and gyroscopes. There are some pretty cool projects that can be done when data can be read off those sensors. I've been playing with the idea of building a two stage out of some spare 3" blue tube I have laying around from my level 2 project and wanted to get opinions on my bay design. I did a 3" bay for my level 2 project and disliked how cramped everything felt. My way around this was to simply make the bay much longer than I did last time, 10" as opposed to 7".
When powered on the arduino would wait for an acceleration equivalent to the 7g's expected at launch. At that point it would wait for burn out, light an e-match in the staging bay to separate the booster/sustainer, and read the gyroscope. If the rocket tips more than 23 degrees from launch orientation, the arduino will not fire the second stage igniter. Stratologger CF altimeter's operate independently in both stages.
This is my first solo two stage project and am starting at the electronics bays to make sure that everything will be safe. I'll need to do testing to see if the arduino uno can even light e-matches and small igniters. I also have a pet GPS tracker on board with a pre-paid sim card for tracking in the sustainer. It still looks pretty packed but I think the layout of this bay is much smarter than my cramped level-2 project electronics bay. If I find I need more batteries I have plenty of room, as well as room for an 808 camera for on board video.
