I’d noticed on my GoPro HD HERO2 camera mounted on my mountain bike that there were some clicking noises on the video recordings. I normally mount the camera on the handlebars and, at first, I attributed the noise to my bike; perhaps a cable hitting the camera housing.
But then I came across a passing comment in a forum that complained about the internal noises from GoPro cameras. Intrigued, I searched online. There were some comments regarding the helmet-mount (and similar) and the need to insert the rubber “thingy to stop the camera rattling around in the mount; I already knew about this and it was not relevant. Soon I came across a number of posts and articles about a rattling being generated from within the camera itself. So I picked up my camera, in its housing, and shook it near my ear. Sure enough, I could hear the rattling! It was also very evident on subsequent recordings I made just shaking the camera by hand. Oh dear. So not my bike after all.
However, I found a DIY fix which required opening up the camera and putting some small foam under the shutter button so that the “micro-switch” doesn’t rattle around. I debated whether to just return the HD HERO2 under warranty or attempt the DIY. I went for the DIY. Here’s the fix:
It worked. Dead easy. No more rattling! Very pleased now. The internal rattling issue is not uncommon and I am not sure what GoPro are doing to resolve the issue for existing and future cameras.
I added an additional mod to the above but only in my paranoia about noise and not really based any tests. The power/mode button (not its micro-switch) will rattle when the camera is not in its housing so I added a very small piece of self-adhesive foam (and I mean small) to the “power/mode” switch inside the camera housing; this was to stop any chance of the mode switch rattling around:

This particular mod is probably not required but I had some foam to hand and it only took a few seconds to add. It’s important, though, that the foam not be too thick otherwise it will activate the power/mode switch when closing the cameras housing. Of course this doesn’t stop the power/mode button from rattling when the camera is not in its housing but some tape over the button may help to fix that.
Alternatively, I could have gone the whole hog and put some padding inside the camera for the power/mode switch like this chap:

Anyway, silence!
