Only thing wrong with that instruction sheet for the LEDs is that its using a resistor size specific to the ones he used. Somewhere in here there was a post that had a link to where you could find out the correct resistor to use.

Otherwise, yes its very easy to do your own mods and is the recommended way. Personally I think something that simple should be done by each person themselves. Something more complicated like a full front panel replacement is more of a mod that I could see being sold. Gotta get your hands dirty and some point in life.

You can use any size of resistor you like, including surfact mount resistors. The resistance value for a 5V source sinking a 4.5V LED should be somewhere in the neighborhood of 100-500 Ohms, with 220 Ohms being the usual solution.

Some older blue LEDs required more voltage than standard LEDs, thus the smaller resistor value in the plans, I would assume.

Yes, that is a good site. The LED section is outdated, though - most new blue LEDs are down to ~3V @ 30mA, although there are exceptions. Some of the wild ones: ETG makes a two-lead, three-chip full color spectrum LED that features an integrated microchip. Simply supply power, and it slowly cycles through the whole spectrum of colors - perfect for mood light mods! Lumileds has a line of LEDs so bright that they can be used for household spot lighting. Nichia has violet and UV LEDs, not to mention their uber-cool 5mm RGB LEDs!! Tired of your blue Xbox mod? Just dial-a-color! biggrin.gif Cost too much right now, though. sad.gif

One other note about that page - it has a section that shows two super-bright LEDs in parallel, sharing a single dropping resistor. While this can be done, it violates industry best methods/standard practices as it introduces a greater risk of single-point failures and compounds any fluctuations/flaws in the resistor used. Not a huge deal, but as a typical resistor costs only a fraction of a cent, there's no reason to link LEDs in parallel.
