Low Budget Air Space Photography 162

Posted by CmdrTaco from the because-you-can dept.
An anonymous reader writes "With a budget of just 350 pounds, two British PhDs in engineering sent a balloon with cameras attached to a height of over 30 km." The photos and video are pretty amazing. Especially the very hi-tech styrofoam box.

    Are people supposed to get air clearance before launching a balloon that passes through altitudes used by commercial aircraft. Just curious.
  • Is there anything they've improved upon versus the other dozens that have been done? I'm too lazy to RTFA after the nth one of these stories.

  • If you watch the video carefully, you will see they invented time travel as well!

  • And at least three Slashdot stories in the past couple years. Its a pretty common science fair project now.
    The "swiss-army-knife" smart phone is the device that makes this possible. It does almost everything you need for a couple hundred bucks..

    • Indeed. I'm surprised this story keeps getting posted every time some group of geeks decides to do this. It isn't newsworthy anymore and the pictures, while great for amateurs, are not so worth my time compared to NASA or USAF photos.

      If these were Ph.D. graduate students, they don't have a whole lot of disposable cash in their pockets. Feasibility comes down to how much do they want to spend of their own money on something that might be destroyed or lost, or how much feature creep do they want when they just want to launch it. If their motivation was to move the bar on amateur balloon launch innovation, then perhaps they could/should/etc. have done what you suggested or much more. However, if it was something more like the desire to

      A fisheye lens would do - couple of those and you only need two cameras - use video processing to stitch the two movies together and you have a full 360x180 view. Or get one of those "Gorgon Stare" military surveillance camera systems.

Anyway this hardly is something new since there was this £500 launch this summer in fancy orange styrofoam http://www.dailymail.co.uk/sciencetech/article-1288688/The-incredible-pictures-edge-space--taken-30-digital-camera-attached-balloon.html [dailymail.co.uk] and even this 150$ launch from September 2009 and subsequent Project Icarus http://www.wired.com/gadgetlab/2009/09/the-150-space-camer [wired.com]

  • I expected there to be less swinging and swaying well above the clouds. Commercial jets, at a mere 10 km high (very roughly) are able to often find very still air. Three times higher isn't very very very still? Do we have any experts here?

          Using long tether helps a bit... or an aerodynamic 'brake'/ribbon while going up. But generally: good question, for something so dainty, and with such weight constraints.

          In my occasional toying in this area I might even one day try a variant of Picavet suspension [wikipedia.org], or segmented tether made from partly-rigid segments of unequal length (to get in the way of clean or even self-exciting oscillations), just to mention two (quite possibly ineffective) ideas (plus especially the second might have problems with r

              Hm, still quite expensive, when compared with new Canon digicams (A1200 and A2200 just around the corner...), and almost certainly not so nice video capabilities - heck, none of the other big digital camera makers comes close to Canon now in video (and I'm thinking about really ridiculously wide FOV / total fish-eye, to have a shot at stabilization in post-production ;>> / video per se isn't even required, just time-lapse of most-of-surface-capturing photos)

                Canon makes nice cameras but the OP was looking for an inexpensive fish-eye lens and these Canons are merely wide angle (28mm) ... no where near fish-eye (10mm). (It also apparently lacks image stabilization.) The GoPro has a 170 degree field of view.

                Also, the price for the A1200 is $229 which is not much less than the GoPro at $259.

      Simple answer: Stillness isn't a monotonic function of altitude.

      Simplified more complicated answer: Air comes in layers, many layers, depending on the local weather, but there are generally several major layers covering the whole earth (stratosphere, troposphere, etc.). Each layer has its own characteristics of temperature gradient and general wind pattern. Between the layers is where the most turbulence is, because air really doesn't like shearing. And in one of the upper layers winds of hundreds of kph

      At high altitudes there's much less friction from air to dampen oscillations.

    • The payload is suspended from the balloon and is essentially a pendulum. Any buffeting or motion takes a while to damp down. Just the simple motion of the balloon itself might be enough (I don't know the damping function well enough to figure out what frequencies and amplitudes of forcing functions are relevant).
  • Good example of "duct tape engineering". After all, it is not recommended to use duct tape on ducts.
    • Its called "duck tape". The plastic backing causes water to bead off rather than soak through, just like a duck's feathers. "Duct tape" has a foil backing that is airtight but not very flexible.
    • I've found that it's a much better idea to use duct tape on ducts, than to use gaffer tape on gaffers.

  • It was news the first time someone did it, but not the 100th or whatever we're up to now. I've lost count of how many times slashdot has run "balloon takes camera to edge of space for $x" stories.

  • Many have pointed out that the idea is not new and they are right. Although, IMHO, it is still cool to see stories about near space activities by amateurs.

    Here are some resources to explore:
    * Nuts and Volts magazine has run an excellent series of articles on constructing all sort of instruments and flight gear for near space projects. Including the basics of regulations, etc. (US centric). They still run the odd piece now and then on updated and additional tech solutions from readers.
