Will you help me build a electronic circuit ? plz

[liteglow]

Hi there

I usually like to help people whenever there is something I can do to help
And sometimes there is..

But this time I myself need some help !!!

I`m building myself a Laminar Jet Water Fountain (jumping water) !
The build of nozzle, and water pressure tank is almost complete :-) !

But when it comes to electronic components it stops :\
I know how to solder, and I know what a IC is !
But I don't know how to build them together in a Circuit ....

So I ask gently if there is someone here that want to help me in my "Garden Project" :-D ¤ puppy face ¤


What I need is :

One circuit that will shut ON\OFF 4 different relay output !
One output to each Jet Nozzle !

I want the circuit to have 4 relays where they come ON\OFF in sequence order, or maybe also random order..

Maybe I also need 4 pot meter to adjust the ON\OFF time ?
Basicly it just 4 different circuits that turn ON\OFF the relays so the water jump

Is there someone that can help me make this ?

Second question..
Where can I get a solenoid that is powerfully to turn the shutter ON\OFF ?

here is a video showing the shutter in action :

And here is a video of how my project will end up in the summer :

I really really hope someone here want to help me
I promise to give credit to whoever can help me finish this project .


Thanx

Filip

I forgot to mention that there WILL be lasers included in this project

Here is my first test with one of my home-made nozzle ..

The effect is pretty cool, because you got a 100% optical light from the water jet..
So when you cut off the water beam, the light will travel with the tip.

Just throwing this out there... if you have any programming experience (any language, you can possibly even script it) you can use a 5V logic relay to turn the jets ON/OFF and feed the output from a parallel port on an older computer to the relays.

Obviously the better thing to do is to use a PIC and write a simple sequence program

That looks slick!! NICE!!

How much were those jets?

Any thoughts about using DMX-controlled relays to trigger the fountain jets?

You could then control your fountain jets using a stand-alone DMX controller, OR use a computer-based controller and sync your fountains to music - along with your lights & lasers!!

Sounds VERY cool -
Hurry up and build it already!!

DMX would be excessive for this project, especially if its just 4 relays that are being operated.

Hmmm...I think of it more like long-term usability, especially since the use of lasers was mentioned!

4-channel DMX relay boards can be had for $75; basic DMX stand-alone controllers can be found for just over $100, or USB PC-based controllers can be found for around $100, with lots of free software readily available.
Several lower-cost laser controllers - including the Pangolin FB3 - can be triggered by DMX.

PLUS -
If Liteglow decides to go the Pangolin LD2000 route down the road, the DMX output (and input) capbility & controllability is built-in already!

DMX is over the top for this installation.. The links lasernerd posted are a great pre-made starting point, the PIC will need to be reprogrammed.

Hi and thanx for the reply

Everything you se on the video is made by me..
I did mount the nozzle myself

The cost on this project need to be low .
As all I need is just 4 relay .. (if I want to advance I hope to maybe add more outputs) !

I`m at work now, but I`m intresting abou that idea of using an old computer..
And use the LPT output maybe ?
(I think I know somewhere you could buy a 8\16 channel relay output device to LPT??)

But I still need someone to make that program so the reley turn ON\OFF when I want !
And there is where I need help..

I dont know how to program at any langue ....

The best part would be if I got maybe 8 channel output.
So I can have 4 relays to shutter the water jet beam !
And 4 relay to turn on off the Light that will be on each beam of water.

Yes I would love to start assemble this now..
But it`s 5-20C minus outside now :\
I hope the snow is away in april\mai ..

Thanx for all help so far :-)
