I’ve purchased another piece of equipment for the balloon project – a micro digital video recorder.
Specs:
Video Resolution: 640 x 480 @ 30fps w/Audio
Field of View: 70 degrees
Memory: 4GB
Max Recording Time: 2.5 hours
Dimensions: 82 x 28mm
Weight: 20g
20 grams of extra weight will only require an additional 0.72 cubic feet of helium – rounding up to 1 cubic foot to allow for the mounting bracket.
Once the DVR arrives, I’ll test it and post a quick video.
