Ok first off I'm wondering if there would be any issue with putting a few 6000mcd blue LED's in my cd drive. I know I thought I read something about possible problems with red LED's maybe messing with the laser, but not sure about blue. And second....is it possible to run LED's parallel/series off a single resistor? I'm wanting to run 3 LED's 2.1fv off of 5v, I have a mess of 68ohm resistors I could put one on each, but I just simply dont have the room for what I have planned. I might be able to make it work, but it'd make my life so much easier to put a resistor inline near the power source. Thats it, any info would be much appreciated Thanks.
