Cg2 Controller Leds Options

[Weirdjerz3y]

Hello all, Im modding my CG2 Controller. Its going to be Black and red. With the red Transparent for leds. My problem is at first, when I had 4 leds, it was nice and bright. I added two more, and they are extremely dim. I want them to be always bright, Like my XCM Light up controller shell. I was reading about posting here, to see how to make it bright, but i didn't find much. I found out about a Charge pump or DC-Dc converter, my problem is, how will i build it?
here some pics of how I installed them. If anything is wrong, or out of place, please tell me. I want this controller to come out nice and bright. And the controller is going to have quite a number of leds. Im going to light up the dome, joysticks, XYBA buttons, and if possible or i got space the d-pad. I already did the triggers, and bumpers.



^This was before I added more leds, and added the transistor.



^my XCM controller, Its always bright, even if its about to die. But the MB on it is a Matrix.
*ignore mess in background, I took these after adding some more leds.
I'm not sure how to resize pictures, so if they are big, sorry. And Thank you for looking at my current project, and helping me out with it.
-I forgot to mention, I have a Pre-programmed RapidFire chip under the pcb, Thats why you see extra wires going to different places.
The PCB itself is for the negative and positive wires for the leds. So all it goes to one easy location.

If you're going 10 more LEDs on top of the 6 already in there, then you'll need a Reg and Transistor (if you plan to use it so it switches on/off on it's own) rated at at least 400mA each, and I'd go 500mA to be safe.

The XCM shell doesn't keep constant voltage, it will dim with battery voltage as well, unless they've changed the board design a good bit since I saw it last. There was no regulation in there when I took one apart, just a couple of Transistors and a Hex Inverter IC as an on/off switch that uses the Tact switch as the trigger. I did this a good while back on paper for curiosity's sake, and have had the board sitting around doing nothing since then, so I just had a look at it again and made up another schematic of it. This one had all white LEDs except for the ABXY, which are colored accordingly.

The controller turns Q1 on/off, so that U1 never has power when the controller is off, thus the LEDs can never be left on all the time. After Q1 is turned on by the controller, then U1 can turn Q2 on/off via the Light button to turn the LEDs on/off. There's no regulation in there at all, least not on this one I took apart years ago.




If you can't see a change from a PnC pack with 1 battery bar, and then plugging up a PnC cable, then they've done something to it that I'd have to see, but I'd wager you'll see a difference in brightness going right from a PnC pack that needs charged to plugging up the PnC cable since that's a 2.2v (low pack) to 3.3v (charging) difference. When you watch them slowly dim over time it's not as noticable, but wait until the battery pack is low and plug up the PnC cable, if they don't get any brighter at all then they have redone the board in there, but I'd doubt it.
