Hi everyone, A couple of weeks ago I announced my project - 2 days ago I actually launched it! The preliminary website is here, thought some people would be interested. http://www.srcf.ucam.org/~jac208/pegasus/pegasus1.html thanks everyone for all your help over the last few months James |

Pretty cool... How'd you interface the JamCam to the gumstix, through usb or GPIO? Was it a driver you wrote or something open source?

The cameras were independent apart from the shutter mechanism, a GPIO is wired to the shutter and using a simple shell script is turned on every 30 seconds. This simultates teh shutter being pressed and then the canera takes a picture. All the pictures are stored on the cameras mmc cards.

Did you log the altitude, temperature, humidity, etc, along the way.=20 I'm really curious how cold it gets, and how quickly. V2 suggestion: Instead of a parachute, use a steerable parafoil... have the foil controlled by a couple servos who are in turn controlled by the Gumstix. Program the glider to circle your GPS coordinates all the way down. Taking pictures the whole time, of course... For extra points, have it begin with large radius circles, and tighten the circles as it spirals down, so you get a good view of the countryside. For extra extra points, use the wind velocities measured on the way up, to help steer the thing back down. You shouldn't have to chase after your project - it should be chasing you. = :-) |

perhaps if you log the orientation of the camera you can rotate/crop the images so they all match?

How about a small electronic gyro? Googling "rate electronic gyroscope" produced several contenders.

You should try to link an inertial central unit, like that you'll have all the movements in the 3 dimensions of the camera (several sample by second) and then you can correct the picture of all the deformations... this is very complicate, it's a big problem in airborne remote sensing (my field of work ;) ).

When the balloon expands to its safe limit and thus pulls on the string, the valve will release some helium to keep it from popping. To bring it down whenever you want, I'd attach a pin to a solenoid (i.e. actuator from a 5V relay). Nothing high tech, but cheap as anything and something you could probably build from parts on hand. I'd also include enough postage on it to cover shipment from anywhere on the planet. <GBG> -- Keith Olson K-Soft Consulting cun...@ib... hex...@zp... bal...@yp... eah...@wp... dmu...@os... ken...@qw... jst...@im... qe...@vp... yru...@cs... rro...@pd... |

I take my hat off to you, sir :o) Just as a matter of interest, did you use the mobile phone during the flight or just to report coordinates after touchdown? Since it rose to about 10 miles (as far as I can work out), did you loose the signal at all? And how did you decide when to fire the parachute? Was it just based on a sudden decrease in altitude? I agree with Nate's suggestions for version 2. You came within a few miles of the sea this time and almost lost all those stunning pictures forever. Some kind of guidance system for descent would be vital, I think. Either that or you could in some way transmit the pictures home via the phone while in flight to minimise your potential losses.=20 Isn't the next Gumstix going to have host USB for talking to cameras? Best of luck for the next version! Dan -- Dan Taylor Software Development Engineer, JTL Systems Ltd PhD Student, Reading University, UK http://www.logicalgenetics.com |
