DIY High-Altitude Ballooning
The Ape With No Name writes "Ever wanted to see the black of space but just can't pay a cool 20 million to do so? Well, just build your own small-scale, high-altitude balloon like these guys out of styrofoam, duct tape, electrical kit and a 'consumer-grade' weather balloon. They reached an estimated 52000 feet, had all kinds of tech issues, including hacking code to fly the mission minutes before launch. Cool pics and video were taken throughout the mission. Next flight is in approximately 2 weeks with 100,000 feet the goal."

I ask that you please do not stream them. Thanks!
It's almost as exciting as reading how NASA got Apollo13 back, but the fact that the payload just dropped back to earth "randomly" is quite alarming.

or alternatively, stick two pieces of aforementioned duct tape over your eyelids and experience the black of space right here at home.

Yeah - just wait for the sunset.
no...wait a second...that's some nerd's weather baloon..Regardless, alert the FAA!

time is your 6th sense, the wierd ones are 7+
Here's a cool webpage of a group that did something similar. Their baloon made it up to about 94,000 ft. The site has a cool writeup with pictures and such of their project.
The twenty million's not to see the black of space but to actually go there, or close enough to it anyway. I can see space from my back yard without a weather balloon. For free.

If they want to test their balloons with a live person, maybe they can send this guy; I am sure for a few beers he would happily go up.

Since I can not RTFA, ican only speculate it will be much more fun that these guys, that lofted a package on a weathe balloon too, but let it return to the launchsite by using a glider. They got a few flifghts out of it until it presumably crashed into a mountainside.
If these guys are going for 100.000 feet, they will need a very big accesible area to recover their instrument package. given that winds up high may be a stong as 100 km/h, that leaves a pretty big oval your package could drop in.

Although he was just an honorable mention, lawnchair Larry was funny. Here's what he did:

Other that the whole issue of where it comes down (say, in the front yard of that reactor in the background, completely freaking out the security people), doesn't this sort of thing pose a hazard to commercial aviation? Like, say, jet engine ingestion, that sort of thing? I know the odds of an intersection are slim, but I seem to recall that the high altitude model rocket folks have to get some clearances and permission, and all that sort of thing. Just curious what the drill is. No doubt some balloon enthusiasts will chime in - but 52k feet means you're passing through (twice!) many, many common through-flight altitudes.
Full credit on the geek factor, but if this had gone wrong somehow or been perceived as an inbound Scary Payload coming down in the wrong place, it would make the idiots that get busted pointing mid-power lasers at aircraft cockpits look like they're not the only guys not thinking the whole thing through...
Don't disappoint your bird dog. Go to the range.
I was disapointed that this was not a manned balloon.
I always thought that a high-altitude balloon ride to 100,000 feet would be a lot of fun. With the whole low pressure thing, being able to see the curvature of the earth, seeing a black sky, it would be the closest that a normal person can hope to get into space. And this is completly do-able to make it within the budget of the average person from North America, Western Europe, etc. Yes a few people have done manned balloon rides to those heights, but they have always been super-funded. Never normal people doing a hobby project.
"earth "randomly" is quite alarming."
Not really.
1 The earth is mostly empty land.
2. It will have a parachute so it should do no damage with it hits.
3. Even if the parachute fail odds are pretty good that unless it hits someone on the head it will not hurt anyone.
4. Noaa and the USAF have been doing the exact same thing for years and no one has been hurt yet.
See my blog http://ilovecookes.blogspot.com/ for light hearted technical information.
Aha! This is just what I need to conduct my clandestine terrorist operations! I mean, forget model rockets! Those were so last month!
I scoured past articles for this.. but could not find it. There was reference to the steps a guy had to go thru to get FAA approval for launching a balloon- contacting the airport controller, etc, and no one had any clue how to do it.
I saw no mention of permits (before slashdotting) of this sort of information being obtained.... which has me rather worried.
Yes, the odds of coming in contact with a commercial jet at altitudes between 11,000 and 29,000 is probably very small, and and yes it was only a small payload (talk about scaring the shit out of a pilot seeing it up there), but I'd still feel rather safer knowing that the FAA was alerted to a possible flight hazard on a lane- perhaps it should have had a simple radar reflector to show its location?
Wish I could have seen the photos, but I was too busy reading.
This guy who did a similar project:
http://vpizza.org/~jmeehan/balloon/
was very careful to follow the regulations. Not sure if the UT guys knew what they were doing in that regards. Basically, you do not necessarily need FAA permission if the balloon is small enough, just so one does not end with one's payload smashing through an airplane windscreen or blowing up a turbine. To quote above link, one generally doesn't need to file a flight plan unless the balloon:
(i) Carries a payload package that weighs more than four pounds and has a weight/size ratio of more than three ounces per square inch on any surface of the package, determined by dividing the total weight in ounces of the payload package by the area in square inches of its smallest surface;
(ii) Carries a payload package that weighs more than six pounds;
(iii) Carries a payload, of two or more packages, that weighs more than 12 pounds; or
(iv) Uses a rope or other device for suspension of the payload that requires an impact force of more than 50 pounds to separate the suspended payload from the balloon.
