Looks great! Good job on the assembly. So what is that going to do?

Is there a full board schematic for that? I plan on doing one with my own PIC but it'd be sweet if I had a schematic I could go off of.

Edit: I see a good view of the board from the top so I can trace out the connections there, but I don't see one of the bottom. Anyway I could sweet talk you into posting a picture of the bottom of the board so I could trace out the connections on that side as well? Thanks!

Got my 6 foot 1/2 plexiglass rod - its awesome.
http://i48.tinypic.com/29nxi54.jpg
Found this connector at work that slides perfectly on the end and has a smaller input end which should hold my 3 mm fiber cables
tightly and close to the end of the rod.
http://i49.tinypic.com/2e6f142.jpg
http://i50.tinypic.com/28bwh0y.jpg

I will polish the ends of the rod and the fibers flat for a good close match up and hopefully full transmission of light.

I got the heat sinks for the 5 watt LED's setup today. These should keep them cool.

Holy crap lol. Should also work as a nice heat sink should you ever decide to build your own nuclear reactor! Way cool though.

What did you use to weld the top plate to the fins? I've read that it can be tricky to get a good heat conducting weld but haven't tried it myself.

Hi Bruce, hohooo, this looks like you want to build a ICE machine *LOL*
Looks great. I mount my leds with screws and in between aluminium and led bottom this cooling cream, then same as used on the cpu in a PC, works perfect. also you can buy heating cream that is like a glue, but secure it with screws is better. Here you can find a drawing of my setup. http://laminar.forumotion.com/laminar-nozzle-talk-and-pictures-f1/the-guide-for-a-perfect-rgb-light-with-pmma-fiber-optic-cable-t93.htm

Thanks for the Pics looks icy cool

Looks good covewi. Where did you get your enclosure? Have you thought about removing the switch from the RGB board and running wires to a weather proof switch on the front of the enclosure so you can change functions with it closed?

Yeah - you are correct - you could have let me know BEFORE I soldered everything together - one more thing to do.

Fiber Holder

The outlet holes are an exact fit for the 3 mm cable.
I will try to close off the larger area around the outlet in hopes of increasing the output into the fiber.

This is a lighted 6 foot 1/2 diameter plexiglass rod which will be cut down to fit the fountain.
I assume that if the rod can look this good - then the laminar steam will too.

WOW... that is nice !!
Where did you find that LED - fiber holders ?
I want some of that also Smile

And the rods seems like a perfect deal to transfer the light up to the output.

Btw, I consider using a 1Watt Blue laser diode on my nozzle Twisted Evil
The price for 1 single laser diode has come down to 30£ for 1Watt Smile

Thanks - here is the link to the LED's - they are 5 watts each - bright- bright - bright.

http://www.besthongkong.com/index.php?cPath=19_24

The fiber holders fell out of the sky. No deliberate thought went into those - it just worked out.

I use them at work for air line connectors - Liteglow (check your PM)

covewi wrote:I am up and going but the stream is not uniformly lit. WHY WHY WHY???

The plexiglass rod is around 1.5 inches from the nozzles and is BRIGHT !!! But the stream is not uniformly bright - there are light and dark segments.
What is the best viewing angle to see the lighted stream?
90 degree's (sideways to the stream) yields a very poor light show but as you come around towards the end of the stream the you see much more of
a lighted stream.

Magic - I noticed that all of your photos and videos are from the angle I am talking about. Is there a reason for that.

But even then there are light and dark segments to the stream.

HELP

Quoted from another thread:

If I had to guess, I would say its because your stream coherency is so good. Just like end glow fiber cable, if your water stream is really good then all of the light will stay in side and not refract out to your eye (which makes it look dark from your point of view). So the spots that appear dark are actually the portion of the stream that are the most perfect. The lighted portions are the areas where the water is fighting against its own surface tension a little which causes slight imperfections and lets some light refract out.

I would use Magic's idea of "clouding" the water slightly which will cause a lot more light to refract out so it all lights up better. I think he used tapping fluid which you should be able to find at most hardware stores.
