I have the design for a seven color changing lightsaber running a nano biscotte soundcard. The leds are running off battery power directly, bypassing the card, to avoid shorting it. I have a 6 switch dip switch that I plan on controlling all functions with, it's essentially six slide switches glued together in parallel. I'm using this switch because I'm making a lego style hilt and want as small a control as possible in the hole at the base (pommel) below/in front of the speaker.
Switch 6 acts as the kill switch, sending power to the card, crystal chamber led, and switch 4. Switch 5 acts as the momentary activation switch on the soundcard, so basically only turns on sound (to simulate a momentary switch I'll just switch it up and down slowly). Switch 4 powers switches 1, 2 & 3 which power red, green and blue blade lights respectively.
so...
6: kill switch/ card & chamber on (power to 4)
5: activate card (switch powered by card)
4: power to 1, 2 & 3 (the predesignated blade color array)
3: power to red
2: power to green
1: power to blue
My limited knowledge of electronics says I need a risistor on all four led's; The batteries I have should put out about 7 volts. I Think I have the correct Resistor for the chamber led but I don't know how to tell which ones I need for the tri rebel star. Should I put the crystal chamber led before, after, or parallel to the nanobiscotte? Here is a link to the one I purchased,
http://www.luxeonstar.com/any-3-rebel-leds-mounted-on-a-20mm-tri-star-coolbase I used lime 313lm, royal blue 1030mw, and red 106lm. ALSO, will cutting power via color selection to one or more leds increase the power flow to the others, changing what resistor they would need?
