Next weekend, if everything goes well, a 15x30cm carbon deck will fly onboard HAPS-1 -http://www.pegasushabproject.org.uk/wiki/doku.php/missions:haps:haps-1
One end of the deck will be the flight radio, the other is my responsibility, a single camera (Powershot A560 ), stand alone GPS logger (to 18km), and a small wide angle mirror so the camera can see the payload, the chute and the envelope above. Still working on a hacked firmware for the A560 - but the intention is every minute will include 15s of video, and then 5-10 stills in fairly quick succession - with the hope that the rotation of the balloon will give us some mosaics out of each section. More details, some photos etc, later in the week. |

Aren't those based on some sort of magnesium compound, or something else rather volatile? I don't know how they'd behave @ peak altitude (or if they'd work at all.)
All I'm directly familiar with is the US military's Meals-Ready-To Eat (MREs)...and those heaters get HOT really fast upon addition of water, plus they emit some fairly nasty gasses if you catch a plume; it'll bring tears to your eyes, and not just because you ended up with "spaghetti" instead of something sort of edible... Dunno. Packaged chemical heat sources seem to peak out rather quickly & require an external trigger to activate. Sounds complex & risky to me. -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.
