Tri-reb RGB wiring help for noob

**Thalan the Exiled** · 03-13-2015, 10:12 PM

Ok so I just bought a RGB tri -reb. I want to mix the red and blue for purple. I have a 7.4v battery pack running to a 700ma buck. Would that be enough to run them in series? I plan to wire the green as well to a seprate connector so I can switch them fairly easily. But would that battery and buck set up work to run the red and blue together? I know it is low ma for the blue and green but I don't need them to be blindingly bright

EDIT:
Here are some pice of the saber in all three colors. These are all run at 700ma. And the pics are in a day lit room. Damn the green and blue are nice and bright. Can't sait till I get ghem up go 1000ma.

Both LEDs will be powered just fine in that configuration. You will likely get a very pinkish color, as the red will dominate over the blue. With the LEDs wired in series, there won't be any way to tweak that.

For purple blends, it is highly recommended to do a parallel wiring setup, and to add an extra resistor on the red.

Cool thanks. So if I added a 2ohm 1w resistor to the red along with ghe buck puck it would make it more purple? Wish I could figure a way to run the individually so I could switch between the three and combine them. With out using a sound board. If anyone has any ideas on how to do that please let me know. I am no stranger to wiring, just not for LEDs. Could I use small toggle switches after the buck puck to conroll which LED was on? Again someone help me out if they know of have seen a diagram

This is great I've been searching for a while for this info all the stuff I found seemed to be sound boards so this helps a lot would it make more sense to use a 1000ma puck and resistor the red since the blue takes a little more power to run and what about using reostats on all three lights for on the fly blending?

I actually thought about using three small slider switchs hidden inside the hilt so that I could just open it up and switch between the colors. As for the buck puck, I am just using the 700 on them till I can get resistors for them. I think I am over trying to actually mix and get purple. It will be easier to just set it up to color switch. At least till I can afford a high end sound board with R.I.C.E

If you add a resistor to the LEDs in series, they'll all be reduced in brightness. To get a proper purple and not a pinkish shade, you need to reduce the brightness of the red while leaving the blue intact. That's not possible to do with LEDs wired in series. You must do it with parallel wiring.

Yeah I figured that out. That is why I am just going to wire in 3 s.all slider switches inside the hilt. I will have each LED wired sepratly and the positive of each on a slider. That way I can juat unscrew the hilt and switch colors between the three. I won't be able to mix but I will leave that till I can afford a Prizim sound card or better. And I could probably run 2 of them together. I wouldn't get a true purple but I could have more color options. And the blue and green together might look kinda cool, and would be nice and bright.

you could get more colors out of it if you use a multi-position rotary style switch. It's how color changing sabers were done a several years ago long before the color-changing soundboards existed.
