First drive vid

Hi guys,

IVA down, DVLA have sent me the papers, plates have been made, so last thing is to go for a drive!

Sorry about the sound quality, definitely need to get myself an external mic!

Regards,
Andy

Looks like fun!

As an aside, I think your sound problem is due to mechanical noise coming up through the chassis/roll bar & into the camera. I mounted my camera like this: simple camera mount - or at least a variation of it. This design is for 3D printing, but it could easily be made out of 2 sheets of aluminium with holes drilled in the right place. Fix them together with 4 ear-plugs and watch the improvements to picture sound and quality.

In my case, all chassis noise vanished, as did the wobbles in the video.

Yes a lot of it might be through the chassis. Any picture of it mounted to the car?

I have a few pictures - but I did mount my 2 plates on a custom-designed clamp that I created with my 3D printer. Don't let that stop you though, as it's the 2 plates & ear-plugs that are the main components.

camera mount 2

These pictures show my Mobius camera and its mount, but the idea works for most of these small cameras.

I'll post a video shortly that shows the results with this camera mount (I have to put it on YouTube first!).

Excellent use of earplugs!

The drone boys use damper bobbins, the benefit of these is that they are less likely to pull out
For extra security, being hollow it's possible to feed a fishing wire loop through the centre

Search for "vibration gopro dampers" on ebay

Or for a little more money you could use one of these strapped to your roll bar

Yes - the damper bobbins are ideal, but I was going for the cheap option to try out the idea. There are some good designs on Thingiverse that use bobbins, but I got confused by the wide choice of stiffness available, so I went for the easy option.

Anyway - here's the video, although the quality on YouTube is cr*p - the original is 1080p, and I haven't yet found the trick to getting them to use that resolution... UPDATE: It seems to have worked it out, although it still isn't as good as the original.
Most of it is boring, so just jump to the middle somewhere (13:30 is quite a good place! ) to get an idea of the steadiness and sound quality (it's just the on-camera mic).

Thanks David, I happen to have a 3D printer myself so might get busy with some printing....

I can send you the STL and OpenSCAD files, if you want to have a play...
