Balloon and Duct Tape Deliver Great Space Photos 238

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."

      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.

      • Yeah, they thought of it. And they did it. But not for 500 quid.
        • That's because engineers hate leaving things up to chance. Also, when projects are funded by the gov't, they usually have more requirements than just 'take some cool pictures'. And when they did it, they didn't have nice cheap off-the-shelf digital cameras.

          In other words, if they didn't have a bunch of engineers working for a beaurocracy and there was cheap COTS hardware to use, they very well might have done it just as cheaply.

        • NASA engineers expect to receive paychecks. They're funny that way. Hobbyists working in their spare time don't get paid.

          Assume an engineering makes $50k/year (rather low actually). That comes out to $25/hour ignoring benefits. Spending a mere 16 hours (two days, not much) planning, getting approval, building, executing, and reporting the results the project's direct labor comes to $400. Add benefits, overhead for office space, tools, transportation, and you're looking at something like $1,000 + parts.

        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.

          Thanks for that - I never knew about the altitude & speed restrictions on GPSs. I can imagine that would cause some head scratching if you bought the wrong one for one of these projects.

          • by Andy Dodd ( 701 )

            Yup. Also, some GPS units had even more stringent altitude/speed restrictions, not because of "prevent use in a missile" laws, but because of "make the user buy the more expensive unit" product line tiering. (A lot of older non-aviation Garmins had VERY low altitude/speed restrictions and would shut down in non-missile aircraft. Most newer ones do not.)

          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.

        • 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.

          My guess is that sensor was reading heat from direct solar radiation. While surrounded with air, it would lean more towards air temp, which goes down as you go up. Once there is no more air, you're getting very hot when facing the sun or very cold when facing away.

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.
