Friday, we covered a little project that attempted to beat the UK altitude record for an amateur balloon launch. Things don’t always go as planned, but the APEX team did manage to beat the several other UK records, including ones for the longest distance and flight duration for a latex balloon.

The APEX team was originally trying to beat the altitude record set by [Darkside] and his Horus 15.5 payload that made it to 40,575 meters. The APEX balloon was launched and slowly climbed over the North Sea to the expected burst point. Unfortunately for the trackers, the balloon leveled off at about 36km and just kept going.

The total Great Circle distance of the APEX Alpha flight was 1347km, with a total flight time of 12 hours, 20 minutes. The balloon eventually drifted out the radio range of anyone aware of the project. Despite the valiant efforts of HAMs across Europe, APEX Alpha was lost in the “HAM wastelands of Eastern Europe,” somewhere over Poland.

Even though the APEX team lost contact with their balloon, Alpha was still transmitting at the time. The balloon surely burst at this point, so it could have landed anywhere from Poland to Ukraine to Russia. The APEX team is offering a reward for finding Alpha, so if you see a small styrofoam box in Eastern Europe, drop the APEX boys a line.

Of course this flight couldn’t have taken place without the efforts of HAMs across Europe. [Darkside], [2E0UPU], and so many others helped out with the tracking as Alpha passed over the Netherlands and continued towards Berlin. The last contact was made by the awesome [OZ1SKY], who was very gracious to stay up until the wee hours of Sunday morning.

Not a bad flight for something that was supposed to take a swim in the North Sea. If you’d like to see the raw data from the flight, the APEX team posted everything they pulled down.

At 11 AM London time, October 22, the Sutton grammar school for boys is going to be launching Apex Alpha, a high altitude amateur balloon for an attempt at the UK altitude record. Unlike a few other balloons we’ve seen, the Apex team is doing it right and giving everyone the downlink details for the balloon.

The payload for the balloon was built entirely by student of the Sutton grammar school and weighs less than 300 grams. While it’s not carrying a camera for the all-important pretty pictures, the payload does have a GPS module and a transmitter; it’s just enough to do the required testing on the lead up to Apex III.

Right now, the UK amateur balloon record stands shy of 130,000 feet. The team gained a lot of experience with their Apex I and Apex II launches, and they’re pretty confident they have the experience to pull this one off. You can check out the progress of the Apex Alpha flight on the spacenear.us tracker. For us Yanks, the launch should start October 22nd at 6:00 am Eastern time and 3:00 in the morning for the West coast. The team says they’ll be updating that throughout the flight.

UPDATE: Apex Alpha just won’t burst. Any HAMs near Berlin in Eastern Europe are sorely needed. Head over to the IRC chat if you can help.

Take the risk of not recovering your hardware out of a near-space camera launch by streaming the data during flight. [Tim Zaman] is part of a team that developed the rig seen above. It sent 119 image back during the recent balloon launch. This included transmissions from as high as 36 kilometers.

The main hardware included a BeagleBoard with connected Webcam housed in a Styrofoam cooler for thermal protection. Pair that with a GPS module for location tracking, and a GPRS module for data transmission and you’re in business.

But that’s not all that went up. The team built a backup hardware module in case the primary failed. This one also had a GPS and GPRS radio, but was driven by an Arduino.

The radio connection made it easy to recover the hardware. GPS data led the team directly to the landing site. The package came to rest on the roof of a building, but we guess that’s more convenient than getting snagged at the top of a huge tree.

Don’t miss the hardware detail video that we’ve embedded after the break.

The team at czANZO, the Czech Amateur Near-Space Object group, sent up one of the best high-altitude balloons we’ve ever seen last weekend and the resulting video is remarkable.

The team’s build blog (Google Translate link for everyone without Chrome) goes through the design and construction of their payload. Like every other balloon build we’ve seen, a styrofoam cooler is used for the enclosure, but there’s a lot of really neat additions that make this build special.

The team included a cut down device in the event the balloon gets caught in the jet stream. Without this cut-down device the balloon could end up hundreds of miles away from the launch point. That’s the reason for the cut-down device they’ve given, although we suspect it’s an excuse to play around with pyrotechnic rope cutting. The optical and audible alarm is something we haven’t seen on many high-altitude balloon launches, which is odd because it made ground recovery much easier.

The team has a lot of video from the flight that [Pavel Richter] dumped onto Vimeo. We really like the footage showing all of Prague, you can check that out after the break.

[Greg Intermaggio] and [Shumit DasGupta] at Techsplosion launched a high altitude balloon last week that climbed to 90,000 feet above sea level somewhere over California. The play-by-play of the flight is one of the better stories we’ve seen on high altitude balloon builds.

The balloon, christened VGER-1, carried a SPOT satellite GPS messanger to send telemetry back to the ground. We’ve seen a few home brew balloon tracking devices, but [Greg] decided to use an off-the-shelf solution for the sake of simplicity. Like other balloons the VGER-1 carried a CanonPowershot camera with CHDK firmware.

The ground track of the balloon shows it being launched west of the San Francisco bay, going above the 60,000 foot limit of commercial GPS units about 15 miles South of Sacramento, and eventually landing just off Interstate 80 a few miles from Lake Tahoe. It’s great that the guys found an easy commercial solution to the tracking problem (that doesn’t risk a smart phone), but if we did this, we’d predict the balloon’s trajectory before launch.

[Greg] put up an album of some of the best pictures taken by his balloon. If you’re in the Bay Area this weekend, [Greg] and [Shumit] will be organizing a group launch of high-altitude balloons. Seems like a really great way to spend a Saturday if you ask us.

Trackuino is a new open source (GPLv2 license) Arduino APRS tracker designed by [Javier Martin]. If you are unfamiliar: APRS (Automatic Packet Reporting System) is an amateur radio method used to relay small packets of position-tracking data to an online database for easy access and mapping. In this case, GPS telemetry data is used to track latitude, longitude, altitude, course, speed, and time measurements in near real-time via aprs.fi.

Although this reminds us of the WhereAVR that we covered previously, the Trackuino includes an onboard radio so no external handheld unit is necessary. Since the Trackuino was designed primarily for high-altitude balloon tracking, a number of useful related features are also included: dual temperature sensors, support for a humidity sensor, and a remote “cut-down” trigger really make this a complete package.

Initially there was some concern that the 300mW radio used would not be powerful enough to reach the ground-based receivers from peak altitudes. This was clearly not an issue however, as the signal was heard from nearly 600Km away during the maiden voyage. If this still doesn’t sound like enough power, a 500mW radio is also supported.

Make sure to check out [Javier]’s blog for some amazing high-altitude photos and everything needed to get your own Trackuino up and running in no time!

Thanks [Brad]!

Don’t just build a UAV, use it to blow things up. In this case a tri-copter seeks out colored balloons and pops them using low-grade fireworks. We’ve seen this type of flying armament before, but not in a ‘copter form factor. It looks like the targeting and firing is done by an operator, and is not an automated system despite what the text overlays on the video after the break says. The lack of autonomous firing capability makes this delightful, rather than scary. Don’t miss the build log for the tri-copter itself. How do you think this one stacks up to the last 3-bladed build?

Picking up a raw egg is not something we’d think a robot gripper would be good at. But this model uses a bulbous tip instead of claw, which makes crushing the object less of a concern.

That tip is kind of like a balloon. It is stretched full with coffee grounds but air can also be pumped in and sucked out. When it comes time to grip an object, a bit of air is pumped in and the bulb is pressed down on its target. Once in place all of the air is sucked out, locking the coffee grounds around the object. Take a look after the break to see just how many things can be gripped with this technique.

Now the real question, can it bring me a beer?

[Luke Geissbuhler] wanted to send something into space, a fun project his kids could get in on too. Instead of sending up a suite of electronic components they went with consumer electronics. The key element, an HD camera to record the event, is protected by a styrofoam shell and soft foam padding. To help ensure that the device was recovered an iPhone also made the trip, running a GPS tracking program that continuously updated the package’s location. To combat the ill-effects of severe cold some chemical hand warming packs also joined the flight.

As you can see after the break, it was a success. The camera documented an incredible ride, with a balloon rupture at 19 miles above the earth (that must be a calculated height as there’s no altimeter in the package). The pod came down gently thanks to a parachute and was recovered just 30 miles from where it launched.

The Ferret is a high-altitude balloon tracking hardware package. Created by [Adam Greig] and [Jon Sowman], it uses an Arduino to gather NMEA data from a GPS unit, format the data into a string, and transmit that string on narrow-band FM. The project, built in one afternoon, is a tribute to the prototyping simplicity the Arduino provides.

The unit was powered by four AA batteries, using the Arduino’s on board voltage regulator. This provided a bit of heat which helps in the frigid reaches of the upper atmosphere. The bundle above was put in a project box and attached to the outside of the balloon’s payload, then covered with foam for warmth and moisture resistance. This tracking is a lot less complicated than some of the photography setups we’ve seen for balloons. It’s also more versatile because it broadcasts the GPS data so that many people can track it, rather than just logging its location.

Darpa has another contest coming up. You may remember some past Darpa competitions, like the 2007 Urban Challenge. Where hackers, engineers, and scientists alike came together to build autonomous vehicles. The game this year is to celebrate the 40th anniversary of the Internet.

The rules are simple enough, find a bunch of red balloons and mark their latitude and longitude. The hard part? There is only 10 balloons – spread across America. It will take an extreme amount of social network engineering, but it all pays off with first place receiving $40,000.

We received quite a bit of tips, after posting about the 150$ high altitude balloon project, from communities and teams who had done similar tasks. There is more to these projects than simply filling a balloon and attaching a camera, so in order to allow everyone their 7 seconds of well deserved fame, we’ve compiled a quick list of similar high altitude balloons. Catch it after the break.

Do note, these are in no order or rank.

RPI Electronics club, sent in their Imaging Balloon of Science. Supposedly built in under 30 hours and runs Linux.

Bang Goes the Theory had their own Space By Balloon program after being inspired by Joe Kittinger.

Brushing up on my Spanish, Meteotek08 is a dual high altitude balloon that reached a height of 30,000 meters.

Ensure II is a very impressive setup that actually recorded its flight with video cameras (video above).

NSTAR, or Nebraska Stratospheric Amateur Radio, have sent up several high altitude balloons within the past couple of months.

Last, but certainly not least is the Amateur Radio High Altitude Ballooning group who have been sending up balloons since 2001!

Thanks to everyone who commented and sent in a tip!

Ever wanted to be able to launch a balloon into space, track its location via GPS, take some photographs of the curvature of the earth, and recover the balloon, all for the low low cost of $150? [Oliver Yeh] sent in his teams project, Icarus, which does just that. The group of MIT students found that they could use a weather balloon filled with helium to reach heights of around 20 miles above the earth;  their particular balloon achieved 93,000 feet (17.5 miles). Then, utilizing only off the shelf components with no soldering, conjured up a GPS tracker using a Motorola i290 Prepaid Cellphone. They then used a Canon A470 loaded with the chdk open source firmware to take pictures. After seeing the results of their launch, the team hopes that this could rejuvenate interests in science and the arts.

The total weight of the Air_ray including the balloon, propulsion system, power supply, and helium is 1.6Kg. Festo has more specs in this PDF.
