Needing Help with Wiring

[Cujo31]

Ok....

I am kinda stuck and I really need some help here....

Primary parts:

Obsidian 3 Sound Board
Luxeon Tri-Rebel Star (R, G, B)

Battery:

7.4v Li-ion 800mAh 14500 Battery Pack

Along with these items, I am using a momentary A/V switch and speaker.

General Idea

I would like to use Red/Green to get a Orange color....
And combine the Blue back in to get a Whitish color for FOC....

I have been following the basic Obsidian wiring diagram and have most everything
in place EXCEPT the LED.  As I type this, I am able to connect the battery and get
sound from the sound board etc.... the switch works correctly turning everything on
and off correctly.

What I need now is direction on how to get the LED wired up.  Using a recommendation
I saw on another thread, I put a 1ohm 2W on the RED, and a 3ohm 1W on the green and tried that...
(with them on the positive leads to the LEDs) and.... well.... it didn't seem to work....

After wiring it up the way I thought.... I attached the battery... get the Obsidian vocal cue... and then
when I press the AV button, I get a flash from both LED's and I get the shutdown saber sound.... and
nothing more.... repeated presses get the same effect....

So I am stuck. 

Should I just use buckpucks on the three LED's?  Can the buckpucks be dimmed to give me the appropriate
orange color? I am kinda stuck.....

Specs:

Tri-Rebel Colors

Red:
Recommended Operating Current (3)   700 mA
Maximum Rated Drive Current   700 mA
Typical Forward Voltage (4)   2.1 Vf
Maximum Forward Voltage (4,6)   2.8 Vf

Green:
Recommended Operating Current (3)   700 mA
Maximum Rated Drive Current   1000 mA
Typical Forward Voltage (4)   2.9 Vf
Maximum Forward Voltage (4,6)   3.51 Vf

Blue:
Recommended Operating Current (3)   700 mA
Maximum Rated Drive Current   1000 mA
Typical Forward Voltage (4)   2.95 Vf
Maximum Forward Voltage (4,6)   3.51 Vf

Or should I use resistors?  I contacted Emory for advice... but have not
heard back yet..... help me out... I feel like I am close... but not there
yet....

Thanks for the help!

Since no one is helping, i put this together to show where
I am... and to get things checked:



I have everything but the LED attached.... just trying to figure out
that portion... then I can move to installing it in the hilt....

Thank you for ANY help!

i do appreciate it!

I hope somebody will chime in and help you out.  I have only wired single color LED's and have not done FoC or color mixing before so I'm afraid I can't help with that. 

Is there any kind of resistor on the AV switch or does the buckpuck regulate the voltage going to the switch LED?

To your questions on the pic:
1. Yes, the best solution is a BuckPuck.
2. Yes, you can use both the BuckPuck for general LED driving and resistors to tune the colour to Orange in one setup. Actually it's the very same way US builds their sabers.
3. Don't know about that, sorry.
4. You still need a connection (and a resistor) between the + of the switch LED and the + leading to the main LED.

Here's a pic with the BuckPuck, FoC and all other things you can compare your diagram with: http://www.saberforum.com/index.php?topic=8667.msg159971#msg159971

Ah yes.... I forgot to wire up the LED on the switch.... my bad!
That is now taken care of and running correctly

Here is the update:



Thanks guys!

i have the buckpuck ordered.... will figure out the resistors once it comes...

You're right that the Obsidian board needs less than 7.4V to operate, but you forget about the LED which also needs to be powered, and then 3.7V are not enough! I think that both need at least 6V to operate simultaneously, so you will definitely need a 7.4V Li-Ion setup.
