Hey there!

I am about to build my first color-changing saber, and I hope you pros can look over my wiring diagram.

11773

I didn't draw the RICE-cables, as they are really hard to get wrong, even for me ;)

Does the rest look ok to you?

Common positive for the rebel star dice (red with a transistor, I was planning on leaving green and blue without one), general power indicator on one of the switch LEDs (with Dyna-Ohm resistor), 2 momentary switches, and a recharge port.

Again, excuse my horrible attempt at drawing...

Any opinion on this is appreciated! :D

Looks good to me.

That diagram is nice & easy to follow. Kudos. Are you planning on only resisting your red or did you just mean you're putting a 1ohm 2W on each color?

I was actually just going to use a resistor on red.
I never had a blue or green single LED gone bad without a resistor, neither on a NB or directly driven in a stunt setup.

If you were to tell me not to go resistorless, I'd probably reconsider ;)

All main LEDs should have some type of resistor (even if it's a small one) on them.

OK, I have now soldered a 1 Ohm 2 Watt resistor on each positive.

I have tried the LED-module now by hooking it up directly to a 3.7 18650 Battery.

Is it normal that the LED is really dim? You can see the color, but the brightness is nothing compared to even the most basic, cheap 3W LED.
I'm trying a different battery now, but what am I doing wrong here? Wrong resistor value?

The general idea is to use the proper resistor for the color(s) in question. Blues and Greens usually use .47Ohm .5W resistors.

Of course, but red should have been ok...

But I found my mistake :rolleyes:
Thanks!

Just out of curiosity, what was your mistake?

Grabbing the wrong resistors out of my collection! :lol:
I know, I know...

Anyway, after soldering around, and cursing because of the cram-fu, the saber is now fully working. I will weather it some and add some color also, as well as change the emitter for a different one once it's back in stock.

Awesome job! I will one day borrow your diagram for my second saber for prizm!
