I spent half the day making camera mounts...finally came up with a half decent one.
Still a little wind noise and sometimes the vibes make it too blurry, but way better than anything I've tried yet. Still need to refine the clamp mechanism.
It's a 12 Megapixel Sony DCS T-90. I think maybe the "Steady Cam" function might be going bonkers when the engine vibe hits a certain frequency. I'll see if I can get it to stay clear more than not. I'll try a piece of tape over the microphone hole too.
The simple way (for someone with the stock mirrors) is to run a piece of flat stock from mirror bolt to mirror bolt underneath the windshield.
If you have stock mirrors the bolt ends are plenty long. I used short screws with acorn nuts under the turn signals that replace the mirrors. It would be a major ordeal replacing the machine screws trapped under the signals, as I glued them in place.
