My New Bullet Camera.
Tuesday, 20 October 2009
My new pair of prescription sunglasses has brought up its own dilemma. The old non-prescription glasses were attached to my PFD by the bullet camera being permanently attached to the glasses.
With this pair I wanted them still on my head when I took off my PFD, so I had to come up with a solution. After putting on the thinking cap for a while, I came up with the idea of a clip holder mount.
That part of the 'operation' was easy, the problem then was how to attach the mount to the sunglasses that proved to be the sticking point. I didn't want the bracket to be permanently mounted to my sunglasses, so I had to come up with a solution.
Then it came to me, small rare earth magnets! Some people might say having magnets so close to your head might be a concern, but I'm not normal anyway, so this shouldn't be a problem!
The holding power of rare earth magnets is very strong compared to the small size that I decided to use. So they should be able to hold the camera in place, even through surf zones.
I needed to attach two rare earth magnets to my sunglasses, this would stop the bracket rotating around on just one magnet. The problem was to be able to have the magnets far enough away from each other, the bracket wasn't going to be wide enough to mount two corresponding magnets onto the bracket.
So with the help of two part epoxy resin, I shaped an extension to the bracket and embedded the two corresponding magnets into the resin. Once the resin dried, I then shaped the resin around the bracket to form the new bracket.
After a coat of paint, it almost looks like a brought one! All up the bullet camera and mount only weigh 38 grams, so it's hardly noticeable when on my sunglasses. I've also attached two magnets to my PFD for when I don't want the camera on my sunglasses, or for when I take my PFD off.
The bullet camera is new, smaller and has a higher resolution than my original bullet camera. Its output is now DVD quality, but not Full HD, unfortunately. There still isn't a bullet camera that's full HD.
I don't think it's too far away because there is a all-in-one unit called a 'Contour HD', unfortunately it's a bit too heavy to mount to a pair of sunglasses, but it would work well being attached to a helmet.
