Hi, I´ve been seing the tutorial of llamas lighted controller mod but i have doubts yet

I want to use the following and i have this questions

1 led 5mm red for the dome. What resistor i need? 22ohm also?

4 led 5mm white for the ABXY. Do I need a resistor? What is the point that i have to solder it? The same that the dome?

Someone could put images of his instaltion wich can help me?

Thanks

yes you need to use the same spot to power the abxy buttons but i wouldnt use wight for them it dosnt look to good i would used red green blue and yellow for them

and that should help you with the resistor you need

ok, thanks i will try it this afternoon and will comment it

Thanks

I have another doubt. I have change leds smd from the guide button of my two controllers and i have some questions

1. In one of them i have two reds and two blues. Well, when the battery is low, blue leds just iluminate its why?

2. In another controller i have four white leds and when any gun is shooting leds are off but when reloading while holding down RT are on

Someone could help me?

Thanks

someone can help me? why when the battery is low leds blue and white are iluminate a little? With red leds doesnt happen the same, always are with the same intensity

Sounds like you installed the blue and white smds on a Common Ground controller.. The blue and white smds require 3.3v to light properly, and the red only require 2.7v (I think).. So, when the battery begins to die the blue and white smd do not get the required amount of power to be bright, theres nothing wrong with the way you installed them or anything its just the way the controller is made.. If you were to install them on a Matrix controller (Older style), the leds would stay lit the entire time.. And, for the problem of when your shooting, when you shoot the rumble motors kick in which takes power, and this inturn takes power from the smds that require 3.3v (blue, white), but it does not affect the 2.7v smds (red)..

Hope this helped..

Thank you so much, i dont have doubts now, thanks for your help

I have other question. IS there a way to on and off buttons light when i want? Would i have to add another button? How i do it?

Thanks

You could use a simple switch or use a transistor that will make them go off with the controller.

I want that if i am playing at night I can turn on leds and if i am playing in the mornig can turn off the leds how I do this? How would the connection of the LEDs to the switch and the motherboard?

Get a SPST switch and insert it into the power line (or ground). You would have a wire coming from the power point on the controller and it would connect to the switch and then you would have another wire from the switch to the leds (make sure you have the resistors in there somewhere). This way when you flip the switch it will have the power and when you flip it the other way you have no power. Hope that helps.

Ok I will try it. I have seen in somewhere ( i dont remember where) that somebody have the same but he turn on/off even when the controller is off. How its possible?

Thanks for the answer

I use 3x blue LEDs in a wired controllers guide button. I tried lighting abxy buttons but it didnt work out right. Anyways, be extra careful, because I've drilled right through the guide button before trying to make the light come through it well, and you don't want that to happen it's not pretty.

Ok, this is what i can do:



Are the conections right? What resistor could i do? I´m trying to calcule it but i have problems with resistor calculator. Somebody can help me with it?

Thanks

I´m trying to calculate the resistor with the calculate but i have some doubts:

In supply voltage i want to put 3V and desire led current is 20 mA but i dont know what i have to put in voltage drop across the led because they have differents values:

Tricolour 1,9/3/3,2V
Yellow 1,8-2,1V
Blue 3-3,2V
Red 1,8-1,9V
Green 2,8-3,2V

Somebody could help me?

Thanks

Well, as i have opened my controller i thinking that i will try to do this without resistor and will see what happens.

I will post it
