Ok, I have finally completed the wiring diagram for my saber's circuitry. Although I have seen many of these before in the past, I wanted to make my own to be sure. This is my first crystal focus and I don't want anything to go wrong. Keep in mind that dice on the LEDEngin may not be labeled on my diagram correctly but you get the idea.
6260
Here are the resistor calculations. Please note that even though I'm using a 7.4 volt battery pack, I upped the voltage of the pack a bit in the equation for FoC to be on the safe side:
Resistor 1 (LED in power switch) = (3.3-2.1) / (0.02) = 60 Ohm, 0.024 Watt
So I'll get a resistor that's: 60 Ohms, 1/16 Watt
Resistor 2 (FoC) = (7.6-3.7) / (1) = 3.9 Ohm, 3.9 Watt
So I'll get a resistor that's: 3.9 Ohm, 5 Watt
The resistor I need for FoC I can get from TCSS but I didn't see the one I needed for the accent LED in the store. I might have to look somewhere else.
So the 18500 battery pack would be able to discharge a maximum of 2.6 Amps. So 1 Amp will go to the main LED, 1 Amp to the FoC die, 0.3 Amps to power the board itself, and 0.02 Amps to power the accent LED for a grand total of 2.32 Amps.
Hopefully I calculated everything correctly and my diagram is good to go but if anything looks off, PLEASE tell me where I went wrong and I'll correct it. Thank you very much everybody!!
