tri-reb rgb color mix stunt saber

[darkeyedkid]

Okay here I go. I have nice 1'' od metal pipe that's been drilled and cut perfectly. Will make a great hilt. I've been researching how to make an rbg saber that can do color mixing. I'll probably only ever have 2 of the diodes on at a time since all 3 just make a light pink. I'm wondering if 3.7v will be enough for color mixing. I'd be interested in hearing peoples' experiences with color mixing. This will have no sound either.

From what you described, you aren't going to be doing much "color mixing" per se, just using 2 of the 3 dice to make a color, whatever that color turns out to be. You should be able to run 2 dice in parallel with an 18650 easily enough.

[darkeyedkid]

I guess I explained it weirdly. x) When I say color mix I actually meant just a color changing saber whose battery will be able to handle having at least 2 dice on at a time if I want so I can color mix. But if 2 dice can indeed be run easily enough off an 18650 then I guess that answers that. ;)

I've run a Tri-Rebel RGB off a single 18650 with no issues, using one, two, or all three dice. Look up my "Asp" saber if you're interested.

I see you have 3 DynaOhm resistors. I hope you're not planning on using those with the Tri-Rebel? They only provide 20mA of current, and that's not nearly enough to run the Rebel LEDs. Use normal resistors instead.

Well that's all certainly good to know. Just to corroborate what I've seen in my research, the red diode is about 2.3 volts correct? Or is it up to 3 like the blue and the green but just run at 700ma? Thanks SS.

[Forgetful Jedi Knight]

The red Vf is around 2.3V NOT up to 3V. Also, the Red is run at 700mA (maybe a hair more) or pop goes the diode. ;)

[darkeyedkid]

I thought so. Just making sure. Thanks guys.

[Silver Serpent]

Correct. I used a 1 ohm 2 watt resistor on both the blue and green, and a 2.2 ohm 2 watt resistor on the red.

I hope this is a type-o because if you have a pipe with a 1" outside diameter you are not going to fit a battle blade that also has a 1" outside diameteer, inside of it.

[darkeyedkid]

Inner. Inner diameter I mean, lol. x)

I like it.
Before I delve in completely, might a higher voltage be beneficial? Maybe 4.5 or even 6?

[Silver Serpent]

A higher voltage won't help if you're running all the dice in parallel. All you need is sufficient voltage for the highest Vf of the Tri-Rebel dice (3.4v)

Okay good to know. Thanks Silver. Just one more thing, someone was good enough to direct me to this diagram. I don't want to come off that I don't trust him but I'd just like to corroborate with at least one other person that this is a correct wire up for a tri-reb color changing saber. 9610

[Silver Serpent]

That diagram is correct.

[darkeyedkid]

hmmm, there doesn't seem to be a 2.2 ohm 2 watt resistor in tcss. :/

This helps me as well because I was wondering about the Tri-Rebels. Like can you use a 4 AAA battery set up with said resistors?

I don't see why you couldn't. I might just stick with one of the 3.7v li-ions though unless a 4 AAA setup works better with your project.

4 AAA will not last very long, nor will it dish out the kind of current you are looking for to run any type of Tri-Rebel setup. Use Li-ions.
