Balloon and Duct Tape Deliver Great Space Photos

krou writes "With a budget of £500, Robert Harrison used cheap parts, a weather balloon, some duct tape, a digital camera, and a GPS device to capture some great photos of the earth from space that resulted in NASA calling him to find out how he had done it. 'A guy phoned up who worked for NASA who was interested in how we took the pictures,' said Mr Harrison. 'He wanted to know how the hell we did it. He thought we used a rocket. They said it would have cost them millions of dollars.' The details of his balloon are as follows: he used 'an ordinary Canon camera mounted on a weather balloon,' 'free software' that 'reprogrammed the camera to wake up every five minutes and take eight photographs and a video before switching off for a rest.' He also ensured the camera was 'wrapped in loft insulation' to make sure it could operate at the cold temperatures. The GPS device allowed him to pinpoint the balloon's location, and retrieve the camera when it fell down to earth attached to a small parachute."

      Actually the "NASA" types were doing that sort of thing many decades ago, pre maned space flight. If you gave this guy hundreds of millions for a budget he would have probably built a fancy rocket too.

      I read an article about some kids doing that a while ago, but they did it better. They bought a prepaid cellphone with a GPS receiver built in that they reprogrammed to send them the coordinates of the balloon ever few minutes. The basket was a Styrofoam food container with chemical hand warmers that they used to keep the equipment warm. When the balloon landed, they just followed the coordinates the phone sent them.

      They not only thought of it, they did it, although without the duct tape. However, they did use duct tape to keep the Apollo 13 astronauts alive on their way back from the moon (see "Moon Lost" in your favorite library).

      A lot of early NASA weather baloons were seen as UFOs. NASA called the guy because they thought he launched a rocket.

      Hardware

      Icarus Payload Hardware Setup Guide

      This is a guide on how to set up the hardware in the Icarus payload. Currently the payload contains a Canon A560 camera and a custom designed PCB which does the tracking and communication. This PCB will probably be available from me should you wish to have a one at cost.

      Timble Lassen IQ

      This is an excellent GPS with a reasonable price tag. It uses the AND clause before shutdown making it perfect for high altitude work, provided your payload is not moving like a missile :-) The AND / OR clause refers to the manufacturers having to restrict GPS's from being used for missile guidance. Some manufacturers use a rule that is based on altitude OR speed and HAB often exceeds the altitude limit and the GPS shuts down. We favor GPS's that use the altitude AND speed restriction as the payload never excees the speed limits and hence the GPS keeps functioning.

      Radiometrix

      Established in 1985 Radiometrix specialise in the design and manufacture of low power radio products for rapid implementation of high-reliability, cable-free data links. Radiometrix is the industry's leading developer of off the-shelf, licence-exempt miniature radio modules.

      ATMega8

      The ATMega8 is an excellent microchip for this kind of work. There are plenty of good tools for programing this chip using Linux, Windows or the Mac see the software pages for links. An excellent website for information about programming the avr micros, as they are commonly called is AVR Freaks .

      DS1821

      This is a superb low temperature sensor from Dallas Semiconductor (now subsidiary of Maxim-ic). The temperature range is from -55 deg C to 150 deg C making it a good choice for HAB.

      Trimble Lassen SK II

      This is an alternative to the Lassen iQ and was my first GPS. If you want to work at 5v rather than 3.3v then this might be the GPS for you. Once again this uses the the Alt & Velocity rule before shtting down. This is basically to prevent people using these modules in missile guidence systems.

      Gumstix Verdex

      Gumstix develops and sells small, inexpensive, highly functional Linux computers for outstanding development and production systems.

      I agree. There have been at least 3 nearly identical experiments posted on Slashdot in the last two years. All of them used weather balloons that got to around 100,000 feet. It's neat, but it's nothing new. There's no way NASA thought this was amazing. If someone from NASA called, it was a janitor or something, not an engineer.

      BTW, interesting how the exterior temp rose near the apex of the flight - I'm not sure I understand why. But then, this is almost rocket science.

      We're in the troposphere, where as you go higher, temperature goes down (because the effect of the ground heating gets less as the ground gets further away).

      Above the troposphere (which is anywhere from 30k-70k feet high) is the region knokwn as the tropopause, where the temperature is constant (but cold - -53C I believe). Above the tropopause is the stratosphere, where temperature actually increases due to the ozone layer absorbing UV light. I think a good weather balloon can easily reach the stratosphere and see the rise in temperature.

    According to most people, space starts at 100km. It's impossible for a balloon to get that high, because there is no atmosphere at that height - and balloons require atmosphere. Even the blog specifically states:

    FA is a troll and the article likely would not have been published if it wasn't a UK news outlet and didn't include a jab at NASA. NASA funds Spacegrant Consortiums doing high altitude balloon research at several US universities. The one I worked on was very similar except we had a license amateur radio operator so we could legally use an APRS system for tracking the balloon. Back then where was no CHDK to use for a cheap Canon camera so camera was controlled by a 555 timer circuit wired to the shutter button. The highest cost was the helium when you figure in the cost of storing large tanks of compressed gas. Our system was slightly more expensive because the payload usually also contained a logging system that stored additional sensor data like temperature and pressure.
