The next step was to create the payload box. The professor had done this before so he gave us tips on using foam core poster board, hot glue and HVAC tape. We chose to cover ours in mylar by applying a spray adhesive to the surface, then laying a sheet of mylar on it, and using credit cards to squeegee it flat as best as possible. The mylar was applied to the insides of the box before gluing, and the outside afterward.
Working with a professor at my college and Carolina Edge of Space in May of 2010 I, along with a small group of friends, sent a weather balloon 74,642 feet into the sky. This post is mainly about the payload I designed, built and tested for the project.
This project was inspired by many seen recently online where students have been sending cheap payloads into the stratosphere. It started around December 2009 when we all met for the first time to discuss the project. It turns out that one of the professors in the Earth Sciences department focuses on remote sensing (gathering data about earth from satellites, etc.) who had done some weather balloon projects in the past. We all got together to discuss a possible launch.
