ProdigalFrogMaking a 3d-printed Underwater Dive Helmet With A Floating Air Supply
KorhakaFirst thought was nope nope nope to diy diving helmet, but looks like it would be quick to remove so not too bad. Feels way overengineered if you just wanted to sit in your pool though.
I know snorkels get into problems with depth as your lungs can’t inhale against the pressure. But I am curious how deep that would get you. The dead air in the snorkel is another issue but you can solve that easily with some valves or just exhaling through your nose. Bit impractical to have a very long rigid snorkel but a tube attached to a float could work. Just not sure what the depth limit would be before you can’t fill your lungs anymore. 1m? 5m?
His design is essentially a diving bell helmet with a pressurized feed of air from an air compressor, so the lungs don’t have to overcome breathing through a snorkel. He plans to use it in shallow areas around Florida, he was only testing it in his pool.
Though this is awesome and cool, but I feel like we’re waiting for the first “I have no clue about physics or what I’m doing” ending up dead
Considering the other content he’s produced I’d say this guy at least understands pressure reasonably well. The crab reference is a nod to the scary shit pressure can do to … Living things. (There’s some really nsfl shit out there on the topic.)
This is why I keep to shallow freediving or snorkeling. There also isn’t anything of value to see in the water here which helps. Sometimes the water is almost clear enough to see your feet. Did manage to swim through a school of tiny fish before.
Not having to surface as often could be nice, but most ways of doing that involve quite a few risks and/or costs, so a snorkel is probably the best choice.
