    Default Resistor check

    Resistor check for tri-rebel running the rBlue and Red dice. Numbers from led calculator.net and digikey calculator, formula yielded similar results if I did it right.

    Battery voltage 4.5 (3xAAA)
    Red (max)
    2.8v @700mA
    2.7 ohm 2w

    Red (recommended)
    2.1v @700mA
    3.6 ohm 2w

    rBlue (max)
    3.5v @1000mA
    1 ohm 1w

    rBlue (recommended)
    2.9v @1000mA
    1.6 ohm 2w

    Blue accent (blaster)
    3.6v @20mA
    47 ohm 1/8w

    Can't comment on your diagram since I don't have exp with that econo board, but your math for the resistors seems ok.
