Joe Jedi (lightsaber construction Kit) Multi color Modification

[valeon]

My first joe jedi turned out fine....but for some reason the second one seems to have less color combinations than the last one....stumped am I.

Old Batteries?

Dirty lenses?

Also, what happened to mine was the actually led was dirty. Once I used alcohol to clean it up, it was just as bright as my brand new one.

It's not really a brightness problem, its the amount of color combos I can make. I got a ton of choices before, and I can't even get orange this time.

Valeon... it's likely that the RGB LED used differs from the other saber enough where you'll have to bias some of the colors with resistors in a way that achieves the colors you want.

If that is a bit complex... I'm simply saying that (for example) red is over-powering green when you have them both lit and so you may not get the nice purple you hope for.

What you'd have to do is throw in a rotary switch and try different resistors for each turn of the rotary in order to achieve the desired mixture. And yeah, it's probably best to look for that color on a full to mostly full cell charge.

Color mixtures WILL start to get weird when the cells begin to lose power... my guess would be red will continue to get more bias, and everything will lean more toward red. (Yellow will lean toward amber/orange, etc.)

I used little pots on mine (on the red because it was overpowering) ans adjusted the red down until I was able to get all of the color combos that I wanted!

Hola Nova! show up at the kegger from time to time!

Beauty! Thanks!

stupid question, how do you wire the pots into this setup? I think a simple mspaint diagram would suffice.

Simple really, just wire the pot in the positive lead between the board and the red LED. The pot has three prongs use the two outer ones (not the central one) then try the different rotary settings until you get the shades you want!
