View Full Version : Small wiper for Gopro/Flight camera ?

Got this crazy idea, that we should try to make a small servo driven wiper to clean water droplets from GoPro and the flight camera. Just a small 5Gm servo attached to a little blade with some microfiber cloth or some absorbant material .

Would really help when flying in light drizzle or when a drop of water spoils the entire footage.

Thoughts ?

One guy over here in Aussie land came up with putting a stalk with a cloth on it behind the camera but in line with the lens , so when he turned round with the pan it would wipe the lens clean.
Just a thought.

We used a fast rotating clear filter in front of the lens (Arri camera). The centrifugal force spun all the water off.

edit* Called rain deflector. Ours looked different but the principle is the same:

It works by spinning a clear piece of glass in front of the lens at a high velocity (3000 rotations per minute). This creates a centrifugal effect and a vacuum effect which throws water out of the glass

You could try using RAIN-X. I use it on my car windshield and find the droplets just fly off, I rarely have to use my wipers at all.

There is another product called Aquapel. It's more expensive than Rain-x, but works even better.

I know this thread is a little older, but have you guys seen that NeverWet spray? http://www.neverwet.com/ I promise I'm not a shill or anything. I've just seen a couple postings about it and am hoping to buy a can to put it on my GoPro lens to see how it works. Apparently you can put it on electronic components as well to protect them.

Yes and in the process your image will be tainted. There is no chance that it's optically clear from a hand application.

The Aquapel and Rainx are made for glass. The stuff you mention has different application.
