Just a quick question i read that for the CP soundboard i do not need to use a resistor/'s for the Tri-Rebel, is this correct? if not can someone clarify what the appropriate resistor would be for this set up (R/R run in series, W for FoC).
and also for future reference how do i work out what type of resistor i will need when using the Tri-Rebel led and PC 3.5?
For the main LED channel on the PC, you do not need a resistor. There is an LED driver on the board that will regulate power to the LED. If you have the two Reds in series, they will both be powered by the onboard driver. You will still need a resistor for the White FoC.
For calculating a resistor, see this post: http://forums.thecustomsabershop.com...e-to-Ohm-s-Law
You can also use the resistor calculator in my signature, though it tends to round up values for safety.
thank you very much! very helpfull. :p
oh also just quickly regarding resistors, do i need to use a resistor for my activation switch or aux switch? both are going to be AV switches.
If you have illuminated switches, then the LEDs in the switches will need a resistor. When calculating your resistor value, remember that the accent pads on the PC provide 3.3v.
