Build Your Own Weather Balloon

Leeji writes "Here is an interesting read about one geek's project to build and launch a weather balloon. The flight recorder is a small $200 Soekris Engineering computer running Bering Linux. It also uses a Garmin GPS, HAM packet radio, an automated Aiptek Pencam Trio digital camera, army surplus batteries, and lots of geek duct tape."

      When sending up weather balloons, flying model airplanes/rockets, making robots or building home computers in your garage are cause for suspicion, then perhaps it's time to re-evaluate what a "free society" is. Hrm, maybe the Canadian winter is worth it... wait, Mexico's warm!

      I'm not one to jump all over the editors for posting dupes; I can sympathize with the amount of stuff they probably wade through. But over the last couple weeks, my sympathy is waning.

      Could it be that hard to at least glance through each day's stories so you know when dupes come in? If you did, wouldn't a "build your own weather baloon" story stand out in your mind at all? If I'm missing something here, please point it out to me.

      On the side of reason, if you see a dupe, big deal. So don't read it the second time. It's like deleting spam; no reason to get worked up over it.... except sometimes it gets friggin' ridiculous.

    One enhancement I would suggest would be to modify the camera in some way so that its power drain was less, even if only for the engineering challenge (he hooked it up to some great big huge massive LiIon cells that would keep a cyclotron going for a while)...

    no seriously... why would you want to undertake a project like this? I highly dought its for the weather aspect of the project. More likely, I think the builder created the whole project just as a large experiment(as he said several times in the article), and this sort of thing I can relate to and encourage.

    So lets think, if I was going to create a large complicated experiment, that involves fairly delacate equipment, would I want to have it floating nearly 80,000 feet in the sky? Thereby greatly increasing the chances of not getting the equipment back in one peice?

    Now if it was up to me, I would choose an experiment that wasn't so prone to breaking things(or landing things on the middle of a freeway). For example I would mod my car with some sterio/radio/computer equipment... or set up a large wireless network in my neighborhood... or something to that effect.

    Just becuase I made the first post doesn't mean that im a troll...

    Actually, :)

    Doppler weather radar works for wind speed and
    direction pretty much always because there is
    always enough reflective material in the air no
    matter how much water vapor is present. It works
    across a "volume coverage pattern" that is made up
    of many "cones" made through repeated 360 degree
    scans at varying angles. This is how you can nail
    with extreme accuracy what distance and height
    air is moving at what speed and direction.
    Granted, I'm basing this on real world experience
    as a certified Unit Control Position administrator
    on the WSR-88D NexRAD doppler weather radar for
    3 years. :) I'm considering this radar as it's the
    one that is in place at most official reporting
    stations. The military loves the thing.

  19. Amateur (radio) balloon tracking by n1ywb · · Score: 4, Informative

    Amateur ballooning can be quite a bit of fun. There is a small but active ballooning sub-hobby within the ham radio hobby. Ham radio is an ideal medium for transmitting telemetry from balloons, since we have access to cheap high quality (and high power) equipment.

    I participated in a balloon tracking experiment not too long ago. The students of Timberlane Regional High School of Plaistow NH launched several high-altitude balloons carrying APRS transmitters, as a part of their CAPSAT (Coordinated Algebra (II) & Physics Simulated Satellite) project. I was able to track two of them. The balloons carried GPS receivers and ham radio Automatic Position Reporting System transmitters.

    The launch was from Hopkinton NH. The first launch went well, and we received good signals from the balloon all the way out into the Atlantic ocean. This was quite a bit farther than they expected the baloon to travel, they had planned on recovering and reusing it :o It was still cool IMHO. Check out this kick ass map of the balloon's track.

    The second launch was also a success, and the baloon only traveled about 50 miles before touchdown. Map is here.

    The third launch went up with the GPS receiver turned off :/ At last check, it was at 00.000N 000.00W. They didn't launch any more balloons that day.

    My tracking station consisted of a Kenwood TH-D7 radio and a PowerMac 7500 604e-180 running XASTIR on Yellow Dog Linux. The full results of the day (and APRS logs for the entire hamfest) are here.

  22. Waiting for Baloon 2.0 by anticypher · · Score: 3, Insightful

    So this geek pulled this off with a minimum of thought. I admire the fact he did it, and was able to recover the baloon. But really, if he had put a little more thought into this, he'd probably have a much better geek experiment. That's why its version 1.0

    The first time he ever tried assembling the whole thing was sitting in a park the morning of the launch. He had never weighed the whole thing until then, and then just randomly filled the balloon until it "seemed right", but that only got him about 60% of the lift he wanted.

    Aligator clips on batteries. Ugh. Plus a quick run home to solder up a permanent connection while his friends hung around the park. Some staging for the week before the flight would have eliminated lots of these little problems.

    He didn't check his ham frequency to see if others were using it, and his QRM walked all over other amateurs in the area, and their chatter kept his unit from receiving commands. Bad ham, no cookie!

    Obscure perl bugs. Wouldn't be a geek experiment without them.

    Bubble wrap for electrical insulation. ZZZZzzzzaaaaapppp!!
