Would this be the type of relay to use?

Yep.
Got a Question? There's a thread for that...

On the Obi Wan, I was looking at it, and where you combine all 3 negatives into the PNP...since you're using the transistor as a relay anyways, is there an advantage to keeping all 3 negatives? or is it just as easy to bridge all 3 negatives and add 1 negative lead, like you did for your vader board?
Is the only point in leaving all 3 just to reduce the amount of soldering?
Yes, it would be a pian to solder all those traces together....
And, if you were going to just power an accent led off those traces you would want to use all three so as to get ~20ma insted of the ~7ma per wire.

but if you weren't? If you are just running it up to the transistor relay?
Would 1 negative work just as good as 3, since you're bypassing the power from the board anyways? Or is there a reason that I'm missing for having all 3 negatives.
Also, looking at the diagram again, do you want the battery positive running through the 5 volt regulator before going to the transistor/resistor/led?
I would think that you would only want the battery positive running through the 5volt regulator on the way to the board, not on the way to the LED.
I don't know, I do know some relays/transistors require a certain ma amount to "switch" or activate. Turning the question back to you, why would you only use one wire?
the 5V regulator does regulate voltage (not ma) to the entire circut. But all 3W LED's only need around ~3.5ish volts to operate. your reds/Ambers need even less...

Just one - from the board IS enough to switch the transistor.

ok im like completely new at this and was wondering if i can get some info like does it matter what led i use with the obi board and which is the best red and blue led
The P4 LEDs are great for most sound cards and LED drivers.

I would like to copy jagahati's setup, except I was going to use a recharge port, a trial rebel, and 3 li-ions. Do you guys think the voltage regulator would be okay with an extra 3.7 volts?? Thanks.
