Watch the video, tons more information.

As someone who launched balloons like these in college, it's interesting seeing so much coverage of these projects. At the time, it seemed like a run of the mill thing to do (we did about 3 launches a year, part of a NASA program) Now it seems to be hitting the news rather frequently.

Anyways, props to this guy. Where we were at least applying knowledge from our fields to write code and create experiments, this guy did some pretty complicated stuff for not having any related background.
