Going For The Amateur Balloon Altitude Record

October 21, 2011 by 24 Comments

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.

Space Camera Streams Data During Flight

September 19, 2011 by 20 Comments

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.

Play-by-play Of A High Altitude Balloon Flight

August 9, 2011 by 16 Comments

[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.

Hack A Day Visits LVL1 Hackerspace In Louisville

July 22, 2011 by 15 Comments

We recently had the pleasure of visiting the LVL1  hackerspace in Louisville, Kentucky. Any hackers in the Louisville area who haven’t visited yet are doing themselves a big disservice.  The space recently had its one year anniversary in July, but it’s hard to tell. The space features many of the things you’d only expect in older spaces such as a laser cutter (added while we were visiting), CNC machines, extensive electronics workbenches, and even a section for those who are into music. The best part about the LVL1 hackerspace is it’s members. We’ve all heard horror stories of hacker spaces with drama or overly restricting rules, but the people at LVL1 are extremely friendly and willing to help.

The Micro Colonel (president, if you wanna go that route), [Christopher Cprek], gave us a tour of the space and its current projects. One of the most impressive is the White Star Balloon project, which aims to fly a balloon across the Atlantic. There’s also the Louisville Soundbuilders which meet at the space every other Monday at 8pm to make new instruments. Some other projects include a telepresence robot, a pony that breaths fire, and a power wheels race car for the Detroit Makerfaire. There are also things such as the Kentucky Open Source Society (KYOSS) that meets at the space. Even a few sumobots were scattered around. We were fortunate that at the same time we were visiting [Brandon Gunn], who regularly does video tours of the hackerspaces he visits, was there too; watch his video tour of the space after the break.

The space usually has an open to the public meeting every tuesday at 7:00, but be sure to check out their calendar for more.  If you’ve never been to a hackerspace before you should definitely make an effort. It’s not the tools that make a space, but the people, and LVL1 delivers.

A Ride Into Space, But Nothing Fancy

October 5, 2010 by 67 Comments

[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.

Arduino Balloon Tracking

March 17, 2010 by 20 Comments

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.

High Altitude Balloons

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.
