free fall will be around 20-45 minutes, all depending on the balloons we use. If we go with something bigger than the other student we might be able to get a longer fall, but once the unit starts to fall there is no ensuring that the camera will be able to get clear pictures so we are just really trying to slow the decent down more than anything.
As far as a heater goes, we arent really worried about the camera surviving at all. yea its going to be a $200 ish camera but split between the people that are working on this we are all throwing in like $50 and it will pay for more than everything (you got to pay to play).
I have also posted a few pictures of some shots done before. Hopefully we will get the same results.
