PC 1.5 help

[patolcott]

Hey so Just need some quick help guys If you can check my wiring schematic to let me know if it is good or not i would be much appreciative. I am including the following

1 LEDengin 10w rgbw for a amber blade with blue white foc
2 14500 7.4v power supply
3 recharge port
4 speaker
5 2 mom switches with accent LED's
6 i power indicator led

I think that is everything. any help and comments and critiques would be of great help

here is link to diagram

Check your wiring on the LEDengin. You are wanting to running the colors in series. Let's take the Main Blade for an example: It looks like you want to run green and red in series. This should be the "chain" from your PC LED pads. PC LED Pad (+) to the Red (+). Red (-) to the Green (+). Green (-) to the PC LED (-) pad. It will be the same thing for the FoC™ just with the different dice.

I'm not seeing anything else that should be a problem. Its hard to tell that's going on with the Accent LED pads, but just make sure you have the switch LEDs properly resistored.

thank you sir

another question... I bought two momentary switches with green accent LED's with a VF of 3.3 volts. now the PC 1.5 accent Led pad Output is 3.3 Volts right? meaning in should not need a resistor for those?

[Silver Serpent]

It's good practice to slap a 1 ohm resistor on there. It's not absolutely necessary, but I'd still recommend doing it.

Ok Thanks

so still having Resistor troubles. I know the formula I am just scared to go forward for fear of messing it up, For my FOC the FV for it is 3.3, what i am having trouble with is since my die are wired in series what is my voltage drop? my FOC is red and green red being ~2.2 volts and green being ~3.0 volts so do I add those together? and for my amperage I know each die should be putting out 700ma so should I double it? then apply? Like i said It all looks strait forward I am just scared LOL.

For LEDs wired in series, you add the Vf together and current remains the same. For the red and green above, you'd need 5.2v @ 700mA.

For LEDs wired in parallel, Take the Vf of the highest, and the current is shared equally between the two. For the red and green above, you'd need 3.0v @ 1400mA to run them properly. You'd also want to put a resistor on the red LED to keep it safe.

I'm a bit confused about what you said above. First you stated that the Vf of your FOC is 3.3, and then you also stated that your FOC is red and green (2.2v + 3.0v). Which is it?

sorry silver I was thinking that the Vf was the supply voltage I said it wrong... that being said with the supply being 3.3 and the Vf being 5.2 i won't even need a resistor then would I?

[patolcott]

BTW thanks for the help silver I am very uninformed with electronics even while reading everything i can. oh and if the VF is 5.2 how will 3.3 even power it? that makes no sense
