Super Soaker XP 90 Pulse Fire

Hi all there, I would like to build up a nozzle, that works as the Super Soaker Pulse fire- ability. I do not have a Pulse fire and isoaker.com does not provide any pics of the mechanic of the pulse-fire-nozzle.

Does anyone know how this "nozzle" does work? Pics would be great or a detailed description, so I know the princip of this kind of firing. Best would be a pic of the opened firing mechanism...

I am thinking of building up a CPS 2000 with such a pulse fire-nozzle, much greater than the XP 90 with big power...may it gives you the feeling of usign a machine gun :D

Post, when you can help me, thanks.

You could try putting a pulsating sprinkler on your water gun. You would probably have to modify it so it will stay in one spot.

I do not think this would work as I want it to...The stream/shoots should keep their full range...Any construction ideas? May i have to get creativ again... :D

If you know anything about electronics, maybe you could connect some electronic stuff to a solonoid valve that tells it to open and close fast.

Hm^^ may this work...but I would prefer a mechanical construction as SS Pulse fire does use...

Does not know anybody out there how this stupid pulse fire works...?

I don't know the Pulse Fire, but I have seen an alternative approach, on the Lanard Waterbolt (and others in the line), which involves using an external crank handle to open and close a firing valve. This would be the simplest system to build, especially since most homemades use ball valves anyway.

The Hydroblitz uses yet another method - a secondary CPS chamber is allowed to expand until its expansion physically pushes the lever that opens the firing valve.

Can you add a link or anything like that? I cannot follow you at the moment, I do not know these weapons...
The hydroblitz uses a nice system, but i would like to build up something that open and close every second or may faster...just like the " AK 47 " assault rifle...

By the way, this is the SS Puls fire(or XP 90)

The XP 90 isn't really like a machine gun, more like a nozzle that is moving backwards and forwards to create a wide fan.

If you want a "machine gun" then you might look at the saturator ak-47's on ebay, to get an idea of design.

Really ? ...Hm, how does it move for and backwards? Spring? That is not good, I hoped to build up a machine gun based on this mechanical construction...

Hmm. that reminds me of the Shot blast's system. I did not know they were so similar.

does anyone know how moving the pipe forward and back makes it pulse?

Also, a spring would only move it one way.

Cantab's post gave me an idea... You could saw off the thing on the ball valve that stops it from turning all the way around. Then you just have to build a crank for it, and you can spin it around to make it open and close.

well speaking of a pulse, the other day i dismantled my metal ball valve to see how it was internally. on the side of it it has a 90 degree restrictor for the lever, when i took the lever off i could keep on rotating the valve, if you can saw off the restrictor which looks pretty easy for me you could keep on rotating from open close only problem is finding the close position when needed and your hand cant really rotate 360 either easily

That is also a possibility, but the pulse should be operated by the water stream itself, as it is done at XP 90 Pulse fire. If you rotate such a metal ball, there is always a time where the it is not open and not closed, something between which will make you loose much water...

The construction have to be operated without or just will really less power, otherwise the stream looses lots of power and range.

try a paddle wheel, with long intervals, when the stream hits it it moves, it spins and creates a small interval between each shot.

That would work, but would waste a lot of water in spray.
