Camera Positioning

I've been experimenting with mounting my camera on my uni.
Here's some video to start:


I used some handlebar stems that are meant for a folding bike as extension bars. I liked how the folding bike stems have a quick release, so they can be adjusted or removed easily without tools.
Unfortunately they just barely clamp onto my seat post, and they won't clamp onto themselves. I had to file one down to make it wider.
I have a handlebar mounting attachment to mount the camera with.

I really wanted to capture myself riding from the perspective of an observer. The extension bars weren't quite long enough to do that well. So I made them longer by connecting some wood bars I made from a broom handle. They fit really well, and would slide together snug enough to not required any fasteners. But they still had a little play when they bounced around, so I put a screw and wing-nut through each.
But even still, there seems to be too much flex in the system. The flex is coming from several places. The clamp to seatpost - the seatpost is a bit bigger than the expected handlebar. The clamp to bar - I filed it, but it's not perfect. The bar to wood connections - there is still some play. And probably worst of all is the wood itself, because wood can flex more.

Maybe some longer aluminum bars with perfect clamps would help. But I'm not sure where I can get them. Maybe I could have them custom made? Probably too pricey.

My ride was ok, but not too exciting. I went back to Whiting, but tried the orange trail. Hills are fun going down, but going up is impossible in the snow. Free mounting is harder, especially with the camera bars. A long stretch on the edge of a field had too much snow to ride in. It just doesn't work. And I broke a bracket for mounting my camera to the bar, so I switched to my helmet mount earlier than I had planned.
And it was cold. The drinking tube to my Camelbak froze solid about halfway through my ride.
But I'm glad I got out. Gotta keep the unicycle muscles strong for the spring!
