Led Mod in a Xbox 360 controller with clear case, some issues

[rafaliyo86]

Hi guys

I want to do a new mod on a xbox 360 controller. I have a matrix controller and i have bought a clear cases. I will put over 20 smd red leds in on the front and 10 in the back. I am going to put all in series to have only two wires in front and two wires in the back.

Then I have an issue. What resistor and how much i need?? Also I would like to put a dyp switck to turn it on and off when i want but i have never use it one. It would be like a normal switch?? I mean, positive of leds would go to the DYP switch and then to the mobo and negative directly to the mobo??

This is what i want to do moreless:



Any help would be great

um just a few tips
 u could wire them all in parallel and not need a resistor if u used the contact on the left of the board (the one we use to power rf on matrix controllers)

in my view this would be a simplified way of doing it.... but ur way would work.. if theres enough power to power that many leds in series......

thanks spurgurgle for your reply. i think i was wrong. I started to do it in parallel not in series because i only cut two wires and i soldered the leds int them
