if one were to make this kind of device, wouldn’t it be better to try and modify a valve system into the can like the valves in a car tire? then you can just plug it onto your compressor and recharge it, and you won’t have to be carrying around a can + a compressor motor… just a thought

A small “air bubble” will never perform as well as the canned “air”. Why? Shake the can you discover the can contains a fluid. A blast from the can consumes that liquid, not compressed air. That is not to say a small air bubble can’t have utility. I have considered building one myself. Using threaded steel pipe and associated fittings. In the even that what ever you build is prone to rust, fill it from a compressed air source equipped with a moisture trap or air dryer. Practically everyone who reads hackaday is ignorant, in some manner. Initial ignorance in itself, is not a bad character trait, but choosing to remain so can be. For that reason, I have no problem with persons pointing out hazards and can’t understand how that’s bad somehow.

Perhaps a better source for a portable would be a refillable fire extinguisher. You’ll have tons of volume and it’s much safer.

Plus you can fill it with a gallon of water and douse people across the street when you’re bored :)

As somebody who owns the exact can pictured in #5 purchased from the same source, let me say authoritatively that is sucks ass. It is officially too good to be true. Don’t even bother trying to ’spray’ liquids with it, because if it’s thicker than alcohol it’ll just come out in a stream. If it is alcohol thickness, it will spray, but only large droplets, and only if you barely put any material in the can. It’s not even that great for air, as there is a safety on the can that prevents filling beyond 80 PSI (it says 90 on the box, but mine releases at 80), and it releases it’s full charge at 80 PSI in about 5 seconds.

Go to the junkyard and find the tank off an old compressor. It’ll be cheaper, and it will actually be worth having.

How is this dangerous? First of all, it’s 50 psi. A can of coke at 60 deg F is 40 psi, and the can in the hack is many time stronger.
Secondly, when a relativly thin walled can fails, it “splits”, as can be seen when one shoots a popcan or throws it against the ground. Unless the metal becomes extremely brittle, there will be no flying debrie.

My dad got me one used oxygen tank (the portable kind that paramedics use) to which he had adapted a manometer (for pressure) a hose and an release pistol (kinda the ones used for aerografies) that can get recharged for free at a gas station… i will post you someday pictures once it returns from a construction site where he needed it for some time.

Cool thing about it? it holds 100 psi but a lot of air, its not like the most portable solution but it takes care of heavy duty work.

seems like a semi interesting hack, I have some cans that run out of propelent before contents and I could really use a good strech.
Anyhow the hacks are all great and I was enjoying the site, then I started reading comments. I can see the internet is the same no matter where you go! Keep the color up it is funny because it has no impact on the site over all, it is just great reading.

anyways steve, isn’t it time you submitted some hacks? I can only imagine what you have created. This is only semi-sarcastic, I really do want to see some of your handy work, in fact I am sure most of us would.

So much BS from everyone about this hack. That’s pretty weak.

In case it wasn’t clear to you: This hack is dangerous.

Solution? : Make your own container out of pipe purchased from a store, when you drill it make sure you glue/weld it properly (JBweld tends to eat some metals) and finally, add a drier to get rid of moisture. (unless you used PVC)

I BULT ONE i made one out of an febreze can and put a tire nozzle on the bottem and put all of the components in an evan sived 2′ peace of steal tubeing so it lookes like one big can and it is rechargeable by li ion it runs with 75 psi takes like 5 secs to fill CAN PUT LIQUDS thru a little attachment i made and a crudely made pvc doc that will charge the li-ion bats in 15 MINUTS FOR !@HRS OF PLAY!!!

don’t any of you guys get it yet? We are trying to get rid of all of the losers out there trying to flame the site off the net. We tried posting hacks that don’t appeal to the normal script kiddie, but they just won’t go back to slashdot. So now we are resorting to dangerous hacks so that their own stupidity will kill them. Stop bashing the hacks and let the losers die goddamnit!

If you guys want it I will submit a hack on how to build diy pipe bombs…
