ok to be honest my grandfather worked at some aeronautics firm some years back. He did alot of work on Reagan Era Stars Wars Program stuff. Designing satellite systems that were armed to shoot down missiles etc. Anyway he has all of these old gyros and other really cool gimbals and such. Boxes and boxes of it.
So on my way over to his house I stopped at Home Depot and bought a caster...pulled the wheel out and replaced it with a ski pole. camera on one end......counterbalance on the other. Duct taped it to my helment and BOOM.
