buttons for waterproof camera housing

[Ronald "Monty" Montemayor]

Hi,

I'm trying to make my own waterproof camera housing made out of acrylic, my only problem is how to make the button that pushes the camera shutter.

greatly appreciate any help.

Thanks

[Justin Eastman]

Use an RF dongle and a small receiver to trigger the camera.  No need for a button on the housing at all...

As always...
Workinonit!

Cut out the acrylic sheet little more than the button, glue a poly film ( with 1mm thickness ) from the inside of the enclosure. Usually these have a bit of elasticity which will be good enough for you click press. Use good quality of adhesive and the poly sheet. 

All the best

Please don't take your housing deeper than 8-10ft, or expect the pressure to spring a leak in most good sealants.

Best,

The best test I've seen for a housing is to take a small towel and test out the housing with it first.  IF the towel stays dry, your camera should be good!

Best,

Astrida

Justin, unfortunately can't use external trigger for this project, trying to keep it simple. but i'll keep that in mind next time. Thanks.

David, I might try this one, I have some poly bags I could use, any suggestion on what type of glue to use, I assume that the best glue for acrylic (Methylene chloride) wont work on polyfilm?.

Thanks Astrida.

Meanwhile EWA-Marine makes housings that fit most cameras and cost $200-300 (and are generally very viable to 140ft depths).

[Tim Dierks]

If you're going to any depth more than a few feet, you can't use actuators which cause the dry volume to vary, or the water pressure will push the button for you.

Ronald, any waterproof adhesive should be fine. Only thing to take is the poly is thick enough and is sealed well from inside.

Maybe using two small super magnets? One attached to your camera shutter button, the other on the outside of the housing with some sort of rubber or spongy material.

Yeah, I thought of that too. using neodymium magnets. I might experiment on this a little later.

my only question about using strong magnets is, it might affect the camera or memory cards? the shutter is very close to the SD card.

As far as electronics go, I think you are ok... perhap though the mechanical stuff but I would not think it would damage anything just make things not move right perhaps???  Just guessing...

SD cards are non-magnetic, so no problem there. There's nothing in a
camera that would be effected either, at least not permanently.
