NBV3 Schematic check please

ok ok...jeez dont pull a kylo ren on me here...lol

Resistor = 50cents. Tri-Cree = $20.

[Silver Serpent]

Yep. And when you don't use a resistor on the NB, you come back here asking why the sound board is giving you constant swing/clash sounds.

The drive parameter is "OK" for fine tuning a SINGLE die (I'd still use a resistor). When you're running two dice on a Tri-LED, you're just going to run into trouble without resistors.

Got it...resistors are cheap and effective...so
for my 2 blue tri cree: 1.8ohms, 1/2w (each)
for the single white tri cree: 1ohms, 2w (single)

[CET]

Blue LEDs usually have similar power requirements as white ones, so you can usually just put them all on the same resistor. I use 2w/1ohm resistors for them, and I keep a bunch of them in my stash.

[oldgamefreak]

So CET you just use 1 single resister for all 3 dies, correct? I'm starting to amass the parts to do the same and was looking at the same colors.

[emperor Vader]

do the resistors go on the positive or the negative? or does it not matter? I've scene a video tutorial where they put it on the negative but then I've seen a wiring diagram where they put it on the positive.

[Greenie]

Pos or neg. it doesn't matter

[Silver Serpent]

That's correct, they can go on either side. My advice: pick one, and be consistent.

One exception: the DynaOhm resistors MUST go on the positive side.
