Hello all of you interesting people. I'm a complete noob here and this is my first post regarding my first custom sabre build. I can't wait to show you all what I've done but that will have to wait. In the meantime, I'm putting together my parts list and getting my circuit diagram drawn up, which I may put up here just to make sure I have everything right.
My question now however is regarding the resistor that can be surface mounted to the Power Xtender board for the FoC LED and well, actually all my LED resistors. And please believe me when I say that I have dedicated 8+ hours to trying to figure this out for myself before asking for help, including a lot of trawling through this forum.
My electronics build is utilizing the NBv2, Power Xtender, a kill switch, 20mm speaker, Tri-Rebel Star RGB LED and momentary switch which is LED illuminated. The FoC will utilise the Blue LED on the Tri Rebel Star and my blade colour will utilise the Red and Green LEDs on the Tri Rebel Star (hopefully to produce a nice amber blade with blue FoC). My power supply is the 18650 3.7V 2600mAh variety. So based on this, am I right to use 3 resistors here (ignoring the resistor for the momentary switch): 1 for the FoC LED and 1 each for the 2 LEDs illuminating my blade? I'm using individual resistors on the blade LEDs since the Red and Green have different forward voltage values and run at different amperage values: Red to run at 700mA and Green to run at 1000mA, or can I manage to run them on a single resistor? From what I've read am I right to use a .47ohm .5W resistor for the Green and a 1ohm 2W resistor for the Blue FoC LED and the same for the Red LED? From my calculations and the obvious fact that the Blue and Green LEDs have the same values, it would seem that they should have the same resistor but since the Blue is being mounted to Power Xtender and Plecter Labs have indicated a 2-3W resistor here I am thinking to use the 1ohm 2W resistor. I hope I've made that all clear and thank everyone in advance for your help.
