Housings: bringing my electronics to the depth

[lairdb]

Charging and updating software is not a problem,. the challenges I see is keeping the screen visje and protected and be super sure there are no bubles.

Acrylic sheet against the screen, pot around that (keeping the potting material from flowing over the acrylic)?

Pull vacuum on the potting enclosure to draw out bubbles: Degassing Epoxy Resin On The (Very) Cheap

I've ordered and used a couple of housings from tecme and can thoroughly recommend them. You just need to provide a goodish drawing of what you want, nothing too technical, and Martin will sort everything else out for you.

I like the idea

Interesting site, not only for this project, but in general.

Not sure if you’ve already gotten what you need but we’ve had some research teams use our off the shelf DRYFOB devices (rated to 1,200 ft) for various projects to house electronics at depth.

Can you do custom holes in your canisters? Looking for something I can run an M24 fitting through, and it looks like your XL housing might work.

Same reason you don't find flat sides on pressure vessels. Pressure changes the shape and they are no longer flat.
The flat sided ones (GoPro housing) will press on the fairly solid GoPro inside the housing to give it structure. The camera is structural support for the housing.
Round pressure housings that can take depth is not difficult. The flat display part is.

Honestly, it's not that hard. Take a look at any of the large format dive computers, they just have a flat 4 or 5mm piece of lexan and a face-sealing o-ring with a smallish air gap to in front of the display to take up any flex.

We don’t do the holes ourselves but others that have used the XL for hydrophone deployment (at 800 ft) drilled out a hole to pass the hydrophone sensor/microphone

I’m not sure what they used to seal it up but if interested DM me and I can inquire. The canisters are anodized aluminum so quite easy to drill through the cap or bottom.
