DIY Water screen

**aijii** · 09-29-2006, 06:45

Anybody here successfully designed their own water screen ? Got any secrets you'd like to divulge?

**Groover** · 10-03-2006, 06:17

I'm somewhat working on an idea on the subject. I havn't come to far but I hope I'll make some progress. As my mother works with garden and landscape design I have been looking at some sort of wateringsystem as a base.

There are three ways to go I think. A dripping solution, spray or mist. I think a spray would give a good screen even if a "dripping" solution would give a more flat surface to project on (http://www.laserundlicht.de/Johannes/index.htm).

I think I'll try to use Gardena watering system as a base for testing. These nozzles at an even distance. http://www.gardena.com/servlet/Produ...egory_rn=12565

Sorry to reply without the full info but theres a compnay in Germany i think that sells them for 500 Euros , it was last summer when i found it so dont remember toooo much except to say it seemed like a good price ,sure it was a 5 metre one , i was thinking of building one to play with at the time ( another job i never got round to ! ) and concluded the time invested in trying to get something to work would be painful and errr wet !and made a mental note to buy one when funds availble !!!!! GUESS WHAT ! i aint bought one ... we have all been there eh !! though Dtpros were just toooo goood to resist !

If no one chimes in due course with th supplier i will try and find it again for you if you too feel it was value for money .

This looks easy to build

I must try something like this in summertime!

Good idea...

Anyone tried to make DIY waterscreen??

I see the link I posted ages ago is not working.

Grave dig bump... I want a water screen... Ideas, designs. 10 feet of 2 inch PVC with 200 holes drilled in it and a hose connector on each end...

Why not make a fog-screen instead of water ?
Less mess

And you can have it indoor.

I did not like that BIG DIY project..
To big, to much noise and the flow of mist was not so focused !

To make the perfect mist-wall, you need to make a laminar flow of mist.

I did a small test here : http://www.youtube.com/watch?v=5-Tgh_33Skg

But it was a test done in 10 minutes :P

I soon receive my 9 head mist-maker.. then I will try to make a bigger one

But if you have allot of mist-makers, and you make a laminar flow with some fans, you can make a decent fog-wall screen i think..

(btw, it have been discussed before at PL )

Nice one liteglow, but I am not allowed to have the lasers in the livingroom; I am willing to bet the kitchen is way off limits.

I also want water, not fog, or steam... a nice sheet of water.

**cruch** · 03-15-2009, 17:45

say WHAAAAAAAT??

**allthatwhichis** · 03-15-2009, 17:47

I meant liteglow...

I was just reading another post of yours and wasn't thinking straight...

**liteglow** · 03-15-2009, 18:19

Waterscreen will be nice

But where do you planning to use it ?

**allthatwhichis** · 03-15-2009, 18:27

In my back yard, right out side the window I point my projecotr out of when it is foggy. It terminates on a privacy fence about 50 feet out the window. There is a water faucet right there.

I guess the most complicated part is the nozzle system.

**keeperx** · 03-15-2009, 21:52

idea..

thats why im the idea man...

done...

**tigerpaws** · 03-15-2009, 22:51

the last water screen that i saw was based in a pond. and they had a centrifugal fan with a fish tail nozzle bolted to the end . and ran a 60/40 water/air mix through the fan.. obv the fan was ip60 + rated.. but it might help

That material is a really good medium for this... I assume it would need a very large hose to move the water, or a very powerful pump, enough to fill all the holes with enough pressure simultaneously.

IMO: the best 'pressure' system is gravity, by using a 6" deep container up top with the water pressure generated naturally across the board. When trying to 'push' water out, not only will it use too much water, but the result is a very unstable stream.

Another thing to consider is perhaps adding a little bit of gelatin to make it tiny bit more viscous. This way it wont splatter all over the place as it's falling down...

bump...

What about water fall based...

**Doc** · 06-01-2009, 14:07

The problem with a waterfall is getting it absolutely level, which means making it absolutely rigid, which means fairly heavyweight construction. Water weighs something like 68lbs cu foot.

Recirculating water with a trough and pump. You would probably need a positive dispalcement pump, maybe a cheap pressure washer pump with a weaker relief valve spring.

As Daedal said, gelatin would probably hepl things (used in firefighting to help colimate the water from fire hoses).

i love this fog screen... i think i will do something similar but is not showed very good oh he build this...

has the fog putted out by the hoover? or there is radial fan on the splitter?

**VJ AIWAZ** · 06-05-2009, 15:53

well here is a test that i did last summer using a sump pump the flow was constant and will run forever unattended but as you see in the pic i need to make some sort of spreader to even the screen to be a square

**VJ AIWAZ** · 06-05-2009, 16:05

and here is a short video of it

**White-Light** · 06-05-2009, 16:38

I'm guessing from the fact that the flow is bowing in slightly that the lip of the bowl isn't uniformally level even though the water is flowing along the whole length of it. Either that or the flow in the centre is greater than at the ends because of the location of the inward water feed.

I would have thought the best water screen reservoir would have been a long shallow animal type trough in strong braced alloy or steel. You could try some cast iron gutter but I'm not sure there would be enough of a reservoir. Whatever you use I would have thought its going to need to have a uniform lip and be perfectly straight and level. I would think you'd also need some means of spreading the water feed along the whole length of the trough so you didn't get uneven inward flow rate along the length. Maybe you could use tank connectors and split the hose feed in so it goes maybe 8 ways or something like that.

I haven't tried any of this so its only theory, but it seems to make sense for a good starting point to experimentation.
