OK, I'm not a huge fan of trying to run 2 main LEDs off of 1 resistor, but then again, I'm not paying for the LED. Also, the 3.1 is a median value, so if say you used 3.2 in it's place, you may find resistor values that are easier to obtain. The diagram looks good overall, I'm happy to see you are putting a lot of thought into this.

Thanks. I'm not a huge fan of tying those LEDs together, either; but I figured using the wiring example in the NB user's manual was a good place to start.

It is. What you would want to do is to put a smaller resistor on EACH (+) going to the LED, after the "Y" split off. Do that, and I think your life will be much easier.

I bought a sound card while they are in stock. Practicing my Jedi meditation while I wait for a white-white-white LED to become available.

Practice your soldering skills, you should.

True. I haven't done any soldering since my son was born. That was seven years ago.

Yeah, this is almost like music school. Some advice and a LOT of practice.

I've changed my design slightly. I'm now looking at a purple blade with the RGB tri-cree LED. As a housekeeping thing, I've also drawn my LEDs running in parallel. See attached picture.

I'm planning on purchasing:

• Red/Green/Royal Blue Cree XP-E2 CopperNova
• 18deg Tri-Rebel/Cree Star Lens
• MHS Heat Sink V3
• Star thermal tape pad (out of stock)

The resistors I am planning on buying are as follows:

Rs - 20mA DynaOhm Variable for white ring LED on AV switch
Rr - This is for the red LED, and I'm not sure what would make the best purple, so was going to get the 1.2ohm/3W, 1.5ohm/5W, and 2.2ohm/5W and experiment to see which one I like best.
Rb - 0.47ohm/0.5W for blue LED
Rg - 0.47ohm/0.5W for green LED

I'd appreciate some feedback on my resistor selections. My resistor calculations are on my wiring diagram. Thanks!

Edit: Alternatively, should I leave out the 0.47ohm resistors and set the value for the blue and green LEDs with the drive parameter on the NBv2 as stated in the user's manual on p. 21?

No issues with the wiring diagram that I can see. The 0.47 ohm resistors are fine, and I would use them instead of adjusting the drive parameter personally.

Experimenting with the red resistor will work fine. You could also pick up a potentiometer and dial in the proper shade of purple, then measure the resistance and get that value resistor.
