I am planning my first lightsaber. It will be an LED saber, with no sound. I know this makes me sound more noobish than i am already, but what parts of the luxeon tri-rebel star are negative and positive? I need to know so I can wire the buckpuck to the LED correctly. BTW, i can't add sound because the soundboards are $100+, and the cost for my saber is already $160, and my parents will only by the parts if it cost $200 the most. With sound the cost would be about $250.
