Help! Questions about virbration absorbtion for SLR bicycle mount

Hey Guys!

Firstly I just stumbled upon this site while searching for answers to my build and on 1st glance it looks great! Loads of cool stuff to try..

Anyway, I'm looking at building myself a camera mount for my Canon 350D to go on the front of my bike.
My main issue/worry is vibration running through the bike and the mount to the camera and damaging it.
I've seen loads of instructions on how to make bike mounts on here, but am still worried about the damage that could be done to my camera (my pride and joy!) if I undertake my project without dampening any vibrations from the road.

I'm going to be doing timelapse/stills photos from the front of my bike around London (not the smoothest of roads!) so want to be sure I won't be damaging my camera doing it. The front of my bike has decent suspension so should take the hit of the bigger bumps but it's the smaller, higher frequency vibrations that worry me.

I've searched as well as I can at 2am but can't find any of the instructions covering the topic of vibration, so I was wondering if there are any mounts or heads out there that are designed for this purpose or if anyone has built something similar with success (or lack of camera damage anyway!)

As I'm doing stills work I don't mind about it being slightly 'wobbly' it's more the vibrations that worry me.
I've found websites selling anti vibration materials (http://www.farrat.com/anti_vibration_materials.html) so I wonder if that could be incorporated into a more general design.

Thanks in advance for any tips or links! And sorry if this has already been covered but I've not found it!

Ian.

Check out retrofilms two Instructables on microphone vibration shock mounts.  He's addressing high frequency mechanical vibrations.

Look here, but mount it on the front of your bike.

You could do something like a steady cam that is mounted off the handlebars.  You need to come up with a 4-bar linkage on an iso-elastic system, which will remove out the bike's vibrations and use the combination of the linkage and weight system to get the CG of the camera away from the camera itself.  You can read about the iso-elastic mounts at wiki. . .

There is already an instructable on this project here. . .

Sorbothane is a very good vibration absorbent used in industry. I have some big chunks of it but it's very old now and getting brittle.

Currently I am working on the same problem (camera on bike). Studied bicycle vibrations (beginning to understand them) and working on a solution with shock absorbers from RC cars (similar weights as a camera).

I've tried similar on a C90 over rough ground, so I have some thought. You do need some king of steady-cam. You can mount things on elastic or springs, but they bounce. It's essential to have some kind of damping (like caitlinsdad suggests). I have thoughts about Lego (Technic), there's friction in some of the components.

Maybe rig up a fluid oil/gas shock absorber from a car or door-closer mechanism to let the camera "float" out the vibrations. You could research how they do those "steadi-cams" mounts for hand-held cameras. Some sort of leveling linkage/counterweight involved. Good luck.

hey thanks for the reply, I'll look into the fluid oil/gas idea. the steadi-cam option looks a little too complicated for my purposes!
