Hello all,

I've done some research and read some of the threads around the forums and think I'm ready to start designing my first saber.

I have everything except the LEDs and resistor or buckpuck planned out. I'm going to use the Rebel tri-star RGB (http://www.thecustomsabershop.com/Lu...Star-P777.aspx) but I don't know how to calculate which resistor to use. I found the resistor chart but it seems to only show for one LED, where's I plan to use three.

I am aiming for a purple but have toyed with the idea of putting control knobs in to control how much of each color is in the blade so that I could switch to blue, green, red, purple, etc.

The rest of the saber is fairly basic. No sounds at this point.

Any ideas on how to calculate which resistor(s) and/or do the control knobs?

Thanks.
