David Windestål is a young Swedish engineer whose hobby is remote control flight. He's part of is a growing Internet subculture that integrates conventional R/C technology and off-the-shelf video technology with the open source movement. Just do a search for "open source" and helicopter and you'll see what I mean.
Windestål shares all his projects online where he not only posts videos of his endeavors but also all his plans and step-by-step instructions. It's all completely beyond me but the openness of his posts gives me the illusion that I could do it myself. After all, the arms of his copters are made of wood and he soldered all the circuitry himself.
But if you have a grand or so to spare, a solid concept of electronics and programming, and several hours to spare, you can make your own POV tricopter that will shoot in HD. Need proof?
