Introduction: Make a Pro Waterproof Camera Case (+ Video)

About: Travelling since 2013. I'm currently in Australia for some reason. --- I’m Calvin Drews, and I love to learn, experiment, invent, create, repair, and generally just do things myself. A sort of modern jack o...

Make sure to check out my blog!

This is how I made a waterproof case for my digital camera. It's not a super detailed instructable...more like a build-a-long. It's full of great ideas on how you can make your own...

One great hurdle this case solves is the camera interface. Mose DIY waterproof (hard) cases don't have a way of operating the camera's shutter. It's usually just turning on the camera and sticking it inside a box while it films.


My lake is frozen, so I'll need to wait until it thaws to get some good pics. I'm stuck with the sink for now!


Step 1: The Box I Used...

 This box is just an airtight food storage box from Dollar General (cost $2.00). If you don't have a dollar store nearby, Meijers ALWAYS has them in stock, but prepare to pay $3.00 and up. Just look in the Tupperware section :D

Step 2: Hole for the Lense

 By itself, this box isn't clear enough for taking picture. You'll need to cut a circular hole in it, and mount a piece of plexiglass/lexan/plastic/ as a lens. I used a hole saw...but a spade bit would work if you can find a large one.

WHEN YOU CUT YOUR HOLE: make it like 3 times larger than your camera's lens assembly! You can't make it too big! But you can make it too small... and that means you have a shadow around you video, called a vignette.

The hole in this photo was too small, so I later enlarged it.

Step 3: The Lens

The lense is just a peice of clear plastic with holes in it. It's mounted with bolts and nuts.

Step 4: Gasket

 Use sticky-backed craft foam as a gasket. You are going to silicone the outside cracks anyway, but the foam makes a darn good secondary defense against water.
The sticky side of this foam is on the lens.

Step 5: Waterproofing the Screws

 Make sure the screw heads are facing inside. Before you tighten them, put some silicone on the threads.

Step 6: Viewing Port

 Cut out a window on the lid of the container so you can see the screen of your camera. Using the same technique you did to make the lens, mount a piece of plastic on the INSIDE with screws, foam, and silicone.

Step 7: My Mistake...

 OK, up to this pint, unknowingly, I made the lens-hole too small! I had to go back in time, and fix it. Don't make the same mistake! Don't make the hole to small!

Step 8: Mounting the Camera

 One of the hard parts of making a custom case is actually holding the camera still! Without some way to mount you camera, it would just jumble around inside...

So I decided to wrap my camera (with the lens extended) in a plastic bag, tape it inside the waterproof box, and inject Great Stuff expanding foam around it. It worked great! Just make sure you don't get any foam on your camera or the plastic lens you made.

Some tips when using Great Stuff: It expands...Just put a little bit inside the box, and it will triple in size after just 10 minutes. Never EVER put to much foam in. It will never dry...If you put too little foam, you can always add more! Just paint some water on the already cured foam, and spray some more foam in.
If you think your foam isn't drying, DON'T FREEK OUT. Just wait 24 hours, and it will almost always be cured.

After the foam is dry, pull it out (it won't stick to this kind of plastic). Trim it with a knife, make it look pretty. I painted mine black so it looked better from the outside.

Step 9: Pushing the Shutter Button

 Ok, this is a pretty iffy solution, but it works! 

It's hard to explain, but here I go..
Get a plastic cylinder that it small enough to push the camera's button. Cut it really short so that it touches both the inside of the box and the shutter button of the camera (when the camere is inside the foam insert, inside the case).

It WILL take some fiddling to get right, so don't give up if it's not quite working.

Now all you have to do it gently squeeze the box, and the plastic cylinder pushes the button! 

Step 10: Silicone...

 Ok, now silicone EVERY SINGLE NOOK AND CRANNY. 
let it cure..
..and get wet!

    I put kids clay in then I put foam over it so that it would be more dense and be easier to dive with but the foam made it fit snug and didn't get all over the camera. Nice instructable! It's my favorite so far. It is both useful and cheap. I have a Panasonic Lumix dmc-lx100 camera and the cases cost from $300-$1050 for a case... it's outrageous...

    Ziploc bag: cheap and easy

    Oh hey disclaimer might cost you the exact price of your camera, just so you know!

    I like your solution to the shutter button problem. Much more elegant than mine. :)

    look really good, thanks for the instructable, i'm going to give it a try

    where would you be able to find a piece of plexiglass like that?

    what if you used caulking, it wouldnt look all that bad. in fact it looks great on mine

    Shouldn't the plastic be on the outside? So that the water pressure will help it seal.

     It's not going very deep. Practicality overpowered functionality in this project.

    I was mainly wondering wy you specified the inside as I can't see wy it would matter.

    The outside of the lid has rough texture, with an embossed logo and such. I was afraid that the rough surface would effect the gasket, so I mounted the window on the smooth inside.

    Just wanted to recommend using 2-part epoxy instead of a gasket, I can't think of any reason you would need to remove the lens and epoxy will be a lot stronger.

     Epoxy has the tendency to look really bad.

    I guess if it's not put on properly it could. When I get my new camera I do plan to build something like this, but probably just out of Plexiglas (I dive).

    But anyway nice Ible.

    Im sure most of you are doing this because its fun to be crafty.... thats great, but just incase; you can buy a waterproof camera bag off ebay for 3 bucks! Works good! They also sell pricier version for like 30 which I also own.
    Oh and a bonus to the bag is you can actually mess with your setting through the bag.

    You're probably right that the poster did this to be crafty, but
    this would be useful if you have a camera like mine:
    www.elitezoom.com/wp-content/uploads/2008/07/fujifilm-s1000fd.jpg
    it's technically a digital camera, but it's still not a DSLR.

    Have a fun time trying to find a case for THAT, and if you do, I'll be surprised, but my point still stands that this is a cheaper alternative :)
    (in case the link doesn't work; it's a fujifilm finepix s1000fd)

    I, like you ,doubted that aswell but it turns out they do have DSLR waterproof bags... makes sense.. they are just bigger bags ;)
    But you are right...in this case  its cheaper to go the crafty route as they Dslr bags are $30-$120. However you will have slightly better control over your camera thru the bag.  I personally wouldnt trust a DSLR in one of these. Stick to cheapo $200 cameras for your snorkeling.

      This actually the cooler and more fun alternative :D

    Congratulations for the idea, the quality of assembling, and the clear explanations. Very good Instructable

    hey nepherton, pretty cool instructable, I was going to buy a waterproof bag for my camera, but it runs around 15 dollars; this is a great idea instead of buying those.
    It would be pretty cool if you added a hole for the flash so you could take pictures underneath the water when is dark.

    where did you get the black sticky foam?

    thanks for sharing
