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.
