There's going to be a meeting at TechShop RDU on Sunday at 6:00pm to discuss the feasability of launching a scientific balloon to "near-space" (70-100k feet). The plan, so far, is to "launch balloon; take photos" but hopefully it will turn into a pretty rockin' project. There is a thread on their forum.
If you have any interest in discussing the project come on by TechShop RDU on Sunday. You don't have to be a member to attend the meetup but you will need to register as a visitor.
Here's a video for a little inspiration.
