Another small Laminar for indoor use ..

Here is another 20minutes DIY project for some indoor laminar nozzles

I let the pictures talk:








The nozzle work perfect
A tiny cute little nozzle, running on a 12volt DC pump from a computer.
The only problem is that the pump is to small, I did run it at 20volt to have the arc as long that I wanted.
So I now need to search eBay for a bigger 12volt pump

It's so cute! How's the dimension of that? Do you use the same type of straw and do you intense to embed light?

Ohh is this a nice little nozzle, i love it. And what a nice stream! Qute. What you want to do with that?

Hi, thanx for the reply

I not so sure about the sizes, as you can see on the pictures, it`s like 2-4" long.
2" in diameter i guess

I have a tiny sponge in the bottom, and the same straws as we usually use.


I think it`s fun and quite learning to make this small laminar nozzles.
As you as usually get the same errors\problems with the small ones that you get on the big ones !

For an example, I first had drilled a hole on the top with a drill = Terrible water output !!
Now I have a metal brass ring = perfect output

Did remove the sponge in the bottom = Terrible output on the water, no laminar at all !!
Now I have 1-2 layer of sponge in the bottom = Perfect laminar output ..

And yes I will place one 5mm LED inside the nozzle to have light effect


I hope the design can be so "ok" that I can have them in my living room...

More pictures..
Both 2 is done, and LED light is added and working (not on the pic)

here it is mounted in a small box, placed in the window

Love them... What is the stream diameter and have you tried to up the pressure to get a larger
arc without the stream falling apart?

Thanks Ken

Hi, thanx for the reply

The stream diameter is 5mm.
I did use a regular metal ring from a hardware store

I can have a higher pressure, and make the beam travel about 5-6" high, ore I can tilt them and make it travel 7-8" away..
But it seems like a higher beam, and shorter distance make the water more stable .

I also not want the water to splash, if the water start to splash it goes on the floor

I also have made a small low-pass filter tank..
What can have been better is to maybe have a drilled brass ring (sharper edge) and better air-tank to remove pump jitter.

Really nice. What about a cutter?
No it's nice like it is. Make a video please.
