Get an led that uses 5 volts or less, because USB only provides a max voltage of 5v. There are plenty of leds out there that use less and are friggin bright. If you get an led that is less than 5v, use a resistor to compensate for the difference. Calculate what resistor you need at this place. Good luck!

P.S. Just PM me if you need details on how to do it. I'm a newbie too and just did this mod last night.

The tut (at least the one linked in my sig) is designed with "standard" LEDs in mind.. 3.3V 20mA LEDs [LSDiodes standard wink.gif ] - which is why you use the 100ohm resistor.

The red USB wire is 5V.
