@tosajd56 We set the interval to 11 seconds between photos. That seemed a good balance between time of flight, storage on the SD card, image resolution, and battery life. We ended up with about 2000 photos but many were dark after sunset.
Did you need to get FAA clearance to launch the balloon? I remember to send up rockets we had to notify them, but I don't know the procedures or anything for balloons.
@zippyman818 The balloon was rated for 90k feet. Since we under-inflated due to helium shortage, it should have gone higher before popping. It flew for about 4 hours total time (GPS
We would have had enough helium with 80 cubic feet (I think), but we used a lot for party balloons in a pre-flight test.
The helium was primarily from Airgas, a local supplier, but was topped off with couple of a party tanks from a Walmart near the launch site. The camera was a used Canon A470, hacked with a CHDK script.
I wonder how many images of the flight you have hanging on the walls at home now? This is cool every time I watch one of these flights.

Great video. We are launching this week. Can I ask what settings you used for the camera? We loaded the CHDK, but don't know what to set it at.

Good luck with your launch!

Approximately how far from the original launch site did the cooler land?

I realized how much it would suck if the cooler landed in the middle of a highway.

Where did you get the helium and what camera did you use in the package? :)

@Andrew4551755 Great, thanks! How big was the cylinder you used (even though it didn't fill the whole thing)

It was 80 cubic feet.
