Sending a camera and a cell phone into the Stratosphere via Weather Balloon.
Great project! Can't wait to see the pictures (here's hoping for safe recovery). I wonder if you could share some of the logistics details (FAA clearance, helium purchasing, Wx balloon purchasing, etc) - I'm wondering if I couldn't do something similar with a bunch of kids at Tinkering School.
After its failed run as a balloon tracking system, it is back to being a Christopher Lincoln tracking device.
