I didn’t see the video, and I know this is old but I have to comment. Commercial “Divers” for things like sea cucumbers in South America use this type of hookah rig all the time. Super ghetto shop compressor hooked up to a regulator. They just dial it in so it’s not too high a pressure. The only thing they die from is the bends from staying down too long, because the system actually works great…

OK even tho this thread is so old, and since the video has been removed the rest of us aren’t actually able to see and judge for ourselves, all the nanny knows best bullshit on here has pissed me off enough that I have to comment. Half of the rants on here seem to be purely that tired old chestnut of “get proper training” – I’ve never been trained on how a Hookah system works but I’m confident that I would be able to manufacture one out of common components if I felt so inclined. What is needed is proper understanding of the principles, as long as this guy was using an oil free compressor and had a way of regulating the pressure i.e. open helmet (trying to use a regulator here would require more in depth knowledge than this) and limited his depth to 10m or so then there is really no problem. All this crap about co2 and co etc is again just that as long as the vent for the air intake is upwind and away from the engine. Without seeing the video how can any of the naysayers on here claim to know that the guy doing this hadn’t in fact thought of all this and was well aware of the principles behind what he was doing???

You internet “guard dogs” should get a life. If someone wants to do something stupid, let them. That’s how something is invented or done at the first time anyway. It’s not your thing to whine or complain, if you don’t like it don’t watch it.

I agree 100%. Except for 1 thing, if those kids somehow attached a certified regulator and used a pump instead of a garage compressor, I could actually see them doing this.

my stepfather dives with a compressor from homedepot attached to a small filter that has a little bit of water in it, attached to a hose attached to a respirator and i know for a fact he doesn’t modify the compressor and dives for a living(cleaning boats). if someone could explain the modifications or why this kind of setup is unsafe it would be appreciated.

Your right; but I think they were trying to build one of these (see link). I first saw one in the Virgin Islands in 1971 and the CO thought scared me shitless then, as it does not. We had one aboard for the guests.

When i was a kid i built a diving helmet out of an ozarka bottle. I cut out the bottom and hooked the air compressor up to the top. The air just came in all the time and excess bubbled out the bottom. I had to bolt 50lb of lead to it to get it to sink. I was aware of the danger of carbon monoxide, this is caused by the oil used to lube the compressor cylinder burning. What is needed is an oil free compressor.

I had an intercom to the surface that i could use by pressing a switch with my head.

Anyway i dived a few times and it was fun, but i quickly lost intrest.

The safety advantage of the bell over a scuba regulator is that you breathe normally and since you ware weighted down you have to walk on the bottom. I suppose if you ditched the bell and swam up from deep you could bust a lung though.

Gee thanx “Offisah Will, Sah”: Thx for keeping da rest o’ us dummies from viewing da video.u is mi hero we all’s luv u for uh, keeping us from frett’n our li’l heads off! u is di only one that could possibly straighten things out.After all u bin at dis diving biznis foh long taim now and like my “big brother” u will protect us from/despite our child-like, ignorant selves. ["...Update: The video was removed after reading my response to it. I went ahead and puled the youtube link since it's useless."]sic. TIRANT!

I can’t agree more with the “rant.” Scuba diving requires accurate, reliable, safe equipment. The simple act of jurry-rigging a positive pressure air delivery system in a closed environment violates all three stipulations from the get-go.
To be quite frank, this person should be dead. His breathing “equipment” probably raised the concentration of carbon dioxide and carbon monoxide to dangerous levels. Whenever you increase ambient pressure you increase the amount of gas which can be solved. The human body can only filter out so much of these gasses, after which catastrophic organ failure occurs.
The skeptics and uninformed may see this as a demonstration of ingenuity, the knowledgeable understand that this fool is asking for death. NEVER EVER LET SOMEONE DO SOMETHING THIS STUPID, ever. Do not ever make your own positive pressure breathing system unless you want to die one of the most painful deaths possible.

it’s amazing how much attention a stupid stunt can get though, this is probably the most commented on story recently put on hackaday, and it’s only about two days old.

The reason to rant about it is because these idiotic activities can impact our chosen past-times.

By and large, I've been impressed with the attention to safety that I've seen in this community. Most of the people that post their creations, do so with an eye to safety and with the understanding that they have no control over who is going to be reading their write-up. Sure, I've got a coil gun downstairs that punches through metal. I regularly engage in pretty hazardous activities. I do all of this AFTER examining the dangers involved, and learning how to mitigate those hazards.

Why bother posting a link at all only to rant about how stupid it is ?
And if safety is a factor, the next time someone adds a gauss gun to his robot should that be censored too ?

(..and for statistics purposes, this is from another AOW diver who doesn't care what people do in their spare time as long as they are too far away to cause me any harm..)

Well, If we don't allow for Darwinisms, This will happen:

Lol @ overproof.

I agree, Darwinian law states that our natural population will eventually balance itself out by fatefully forcing people will kill themselves (usually in a very humerous manner).

Let 'em get on with it, I say, and laugh at them when they do.
