High Altitude Balloon Photography
September 3, 2010
These projects are always something I like reading about and something I long to do some day.
Just look at the kind of pictures you can get (click for full size):
This one is the handiwork of [Timz] and he has done a great job.
Excluding the radio receiver and the borrowed items, this does not seem too expensive especially if you have a few of the components already.
The radio and GSM and dual GPS might seem a bit excessive but having a bit more kit is better than losing your balloon and all the expensive payload.
If you are going to do a similar thing then make sure you check up on the cellular network regulations for where you are, some countries disallow the use of cellular devices when you are not on the ground so you would only be able to use the phone when it had landed.
