Way too many ways for this to go wrong in the hands of dumb people
Comment on Making a 3d-printed Underwater Dive Helmet With A Floating Air Supply
Korhaka@sopuli.xyz 4 weeks agoI can see someone strapping the helmet to their head, then get a leak while 1m deep. They notice when it fills up. Panic and try to get it off, can’t. Surface, it’s still full of water because the leak is at the air entry hole and they designed it to fit snugly around the neck and it won’t drain without tipping upside down. Drowns while struggling to undo the straps holding it on

Iron lung diving snorkel setup. Allows you to overcome the pressure and use a 15m long snorkel!
And you accidentally set it to the wrong depth and blow up your lungs.

How would it blow up your lungs?

Overpressure, 10m deep is roughly double the pressure at sea level.

I’m assuming you didn’t watch the video, but this particular helmet design has a completely open bottom, and it needs weights attached to it to keep it from floating (he attached just enough weight to keep it neutrally buoyant). If it sprung a leak, you would easily be able to remove the helmet either by lifting it up off you, or tilting forward or to the side and sliding it off. it is not strapped to the person at all.

Yes, this one does. Someone copying it may make poor choices and change it in ways that are dangerous.

Hm. Out of curiosity, do also believe that instructional videos of how to do house construction, electrical work, or brake repair on cars should not be freely available to prevent people from watching it and doing incorrectly and dangerously?

Also believe? I don’t think I ever said anything shouldn’t be freely available.
