Underwater Blink Cam

Had a Blink cam sitting around and recently received orange photography film for last week's event (@jccaclimber thanks!). I placed the cam into a plastic jar (from Algae Barn this is) and held the jar against the inside of the tank using two aquarium magnets I had lying around; 2 Two Fishes magnet backs.

I thought there was a good chance the magnets would interfere with the image or kill the camera but the camera works! And it's small -- which has me thinking about locating a proper acrylic tube and cemented magnets.

Two aquarium magnet backs hold the jar tightly against the glass corner. And with the lid in-place, the jar is fairly well-secured. At least for periodic use and prototyping.


I've wanted to see what my fish are doing at the top of my rockwork but they take off for deeper waters when I get close. This should do the trick. And I can watch fresh food dosing when that happens.

I'm going to play around with acrylic tube next.

That's pretty cool! but is there any reason to not just mount it directly to the glass on the outside of the tank? If you just want a fixed view, it seems like that would be safer and easier.

But it wouldn’t be an “underwater” cam ; )

You’re right — safer outside the tank. For whatever reason, guess I want to swim with the fishes. Dropping-in a cheap and small video camera anywhere in the tank is the ultimate goal.

I agree, being able to "swim" the camera around would be neat!
 
I have a webcam that sits on the outside of my tank when I travel. I leave it disconnected the rest of the time as I don't want a camera continuously streaming from my house otherwise.
You would need a way to bulkhead the cable, but a snap-top container might be a nice way to seal that up.
One application I can think of is seeing what fish are doing in the caves down inside the rock stack, or in places not visible from outside the tank.
Nice to know that filter is getting used.
Whatever you use, make sure it can be cleaned of biological fouling.
