I bought the MR build your own saber kit to get the sound card, now I have some cool parts left over. I wanted to make an RGB saber using the 1 watt star it came with. I plan to direct drive the star with 2 batteries. I have 3 small SPST latching switches I am gonna use. The red will be over driven, after talking to a friend he recommended adding a resistor 2.7 ohm 0.5 watt. That should bring it down so I can mix colors without the red overpowering. Is there anything else I need to do?
