Lol@no 3. The first thing i did when getting the new cameras for 3d i dropped one on the floor. It of course broke and i had to take it for repairment without one single shot taken.
When repaired it didn't take equally colored pictures as the other one and recently i got a outsalesexample for a third of the price. Now got three of those cameras but at least stereo is great!
This kind of steadycam might be great for those cheap pocket HD cams like the Flip Mino or Kodak Zi6, etc.
Those small HD cams tend to have a lot of "tearing" in the video like in your demo without the steadycam gadget.
Good job.
Oh, I like that introduction of the parts, "Ladies and gentlemen I draw your attention to the stick, it is a solid stick, I will now pass it over the floating volunteer!"
