I decided to be "that guy" in the neighborhood today and messed around with the GoPro Hero HD camera and the gokart. I mounted one of the stick-on clippy mounts on the toe bar on the nose of the gokart, maybe 5-6" off of the ground, and then mounted up the camera for some laps of the neighborhood. I've got a few videos uploading now, but this one is live:

GoKart Part III

Just trying to find new places to mount that aren't boring. What do you think?

Best video!

You can really see the speed in the last about 1/4 of the way in when I take a right into the other neighborhood into the left/right/left/right section!

Make sure you click the little "HD" button next to volume when you watch. Also, my "channel" has some autocross vids with the same camera.

Nice! I was watching a few minutes of the Chili Bowl coverage on Sat. night on SpeedTV and they were using a bunch of GoPro HDs for in-car cameras, looked good. Not quite up to the usual HD broadcast standard stuff that Fox sticks in the nascar cars, but all in all very good.

I'm interested in what settings you were on for that video, P71. The resolution looks good but the CMOS wobble/jello effect is pretty distracting when the ride gets bumpy. I have noticed this effect on several GoPro HD videos, but I didn't really see it on my RallyX videos. I was at 60fps though, which should minimize that effect. Here's a nice writeup on the source of some common CMOS artifacts, for anyone who is wondering what I'm talking about:

BTW, people are getting some amazing video with this thing mounted on various R/C flying machines. Almost makes me want to go out and buy a plane just to play with the camera on it :).

I've got the Hero system. Will try it this weekend for the first time on an autocross course.

Josh,

Uh, the standard settings? I don't know anything about cameras so I didn't mess with the settings much. I know it has an even more HD and widescreen setting. As for the shaking, my gokart has a bent axle, so don't blame the camera! Notice my other films, including mounting the camera on my helmet, produce stable shots.

Eny body else notice the rolling stop at the stop sigh? Good video tho.

Try it again at 60 fps (I use mode r3, which is 720p widescreeen, the highest resolution it will do at 60fps). I bet it comes out a lot smoother, at least in terms of the rolling shutter induced wobble. At the very least it would be interesting to see the difference between the modes.
