MakerFaire is Geek Heaven. This TV coverage does a good job of sharing the excitement.
At the GeekDad booth, Erik and I demonstrated the construction of some rockets at different scales… and met many interesting people. The first guy that came up to the booth asked a number of questions, and after a while, he casually mentions that he used to work for Wernher von Braun, the scientist who designed a number of rockets, from the V2 to the Saturn V superbooster that took us to the moon.
Next to us, Chris Anderson (editor in chief of WIRED) showed how to build a quick and dirty UAV, with a RC plane + LEGO Mindstorms NXT robot kit + a cell phone strapped to the belly. The cell phone has GPS so the plane can fly to pre-designated coordinates. The cellular system is the wide-area wireless link. And the built-in camera can take photos of targets of interest.
