Fight Computer and GPS

 

I purchased an Arduino Duemilanove mini processor to use as the main flight computer.

I also purchased a Motorola GPS module off of eBay.

I purchased a Canon Powershot A560 which can be hacked to snap a picture every 15 seconds (or any interval).

 
My 600 gram balloon has also arrived, although I may have bought it prematurely. A 600g balloon will only lift 250 grams or about 9 oz! That's not very much.

I may forgo the flight computer and use only the GPS tracker and camera on the first flight. The camera alone weighs 165 g. If I can get the tracker under 100 g I should barley make it.
