Water Bottle Camera Mount for stability

Better technology sometimes causes problems. In this case, technology has made video cameras really small. Small? That's a problem? Well, the problem (as I discussed previously) is that small cameras are not stable and make "shaky" videos. Well, then increase the mass of the camera - simple. I wanted to test this idea and make a test video with and without extra mass on the camera. I was thinking - what could I attach to it? A 2 lb or 5 lb scuba weight came to my mind. Then it hit me: a water bottle.

When do people use these little video cameras? To film their kids or something? If you have to carry around and extra weight, what is the point of having such a small camera? What do people often carry around? A water bottle. It doesn't even have to be a water bottle, it could even be a soda or something. My idea is to modify a water bottle top so that it has a camera mount on it. All you would need to carry is the top, you can put it on anything that has the same size opening (don't all water bottles use the same size cap?)

Here is my first crude attempt. I found a screw that was the correct size. I drilled a slightly smaller hole through the water bottle lid. Put on a washer, some hot glue - done. I think you could do a better job if you put a washer on each side of the lid and maybe a small nut to keep it tight. Here is mine:

And then with the camera on:

I didn't conduct any official tests of stability, but it seems better. (and it is cheap and easy and reuseable)

As I mentioned the other day, some of the kids in the neighborhood and I decided to conduct some experiments into the Mentos + Coke = geyser phenomenon. I thought I'd have pictures and/or video to show you, but due to technical problems (technically, I was the problem) the experiments didn't get…
Let's say you have some liquid that you want to contain without leaks, say, milk for a baby. What do you do? Well, you put it in something like a baby bottle, the components of which are shown here: You have a hard plastic bottle, a soft silicone nipple, and a hard plastic ring that screws onto…
You have no idea how long I have been sitting on this one. I made some videos like a billion years ago, and still no post. Why? Oh well, here it is. I like video analysis of motion. I like looking at stuff on youtube or other video sites. But sometimes, you need to make the video yourself.…

You can't argue with a solution that involves hot glue. I don't even have a camera and I want to build one of these things.

I think I've seen a commercial device for stabilizing movie cameras involving a floating lens arrangement. Probably horribly expensive, though.

One wonders if filling the bottle with water, and, perhaps, adding a few baffles to prevent sloshing, one would build a hydraulically damped stabilizer? Sort of a camera mount dashpot:

Or, if you could build a Stockbridge style damper?

Hey Rhett, I emailed you yesterday and it came back to me as undeliverable. Did you forget some email settings after the server move? I figure this is the best way to get in contact after email!

I wouldn't want the unsuspecting to screw beyond the damage point into their cameras. I've had 2 or 3 Sonys, for example, which specifically mention this danger in the user manual. Not all have "stops" in the screw chamber and/or might not stop a strong twist into the chamber.

Otherwise, great idea to carry a bottlecap. I plan to work on one for myself.
