5mm Blue LEDS in my wireless controller?

**DeadxBeat** · 05-30-2005,05:38 PM

I have 2 5mm Blue LEDS from radioshack, both 3.7 volts, 20mA, and 2600mcd. Is there any way i can put them in my HipGear Wireless controller so that they will be on when i turn the controller on? I took the rumblers out of the controller to save battery power and for extra space, but i want the leds to be continually lit, not just lit up when the controller rumbles.

You can probably hook them right up to the batteries using a few resistors and a transistor tied to the on/off switch somewhere. It would be basicly the same circuit as the mem card activity led except where the leg of the transistor is tied to the data line it would be tied to swithed power from the on/off switch.

can you get a picture of the controllers board...

if you can make sure you take a close and clear pic of both sides of the controller, i will try to put a digram for you if you supply me with the pics...

it is possible, nothing is imposible if your put ur mind to it and focus...

My digital camera is unfortunately not working at the moment. I guess i will just hook them up to the rumblers. Do i need to use a resistor to hook them up there?

Yes, you always want to use a resistor with an LED and never hook them up direct to any power source. You probably only need about a 100 Ohm resistor, if you go too high the LED won't be very bright.

Ahh, do you have any experience with putting leds in the memory card? I saw a post about that but i don't want it to show the activity, i only want it to be lit up whenever the ps2 is on(active, not standby).

**digitalFX** · 05-31-2005,10:06 PM

Yes (in case you couldn't see from my pic). I have mine wired to come on all the time when the ps2 is turned on (out of standby). I used 3.3 volt LED's with 100 Ohm resistors. I know there is a diagram on here somewhere on what pins to solder to.

As a matter of fact here it is...

Well, i know that +3.47v comes out of every lead except for the ground, thats why i was a little skeptical if i would actually need a resistor since my LED's forward is +3.7v. I have a 100ohm resistor though so if needed i can just use that. I found some solder points in my ps2 controller that light up my LED. I have a multimeter but i don't know how to read it, so i just attached a 10k resistor to my LED and tested it on the two points, it lit up very dimly, so then i tried a 330ohm and it lit up bright, then a 100ohm, and it nice a bright for me, so i'm going to fix up my controller today. The solder points i found were the red and black wires coming from the controller wire. If anyone knows the actual volts coming from them please tell me. Also if anyone knows if its dangerous to attach 2 3.7 volt blue leds to them please please reply.

You shouldn't have a problem hooking up two, but don't quote me on that. Basicaly you just want to make sure you don't draw too much power from somwhere that can't supply it. I personally used 3.3 v LED's which are close to your voltage. I used 100 Ohm resistors in line with them and they are still very bright. You might be able to run the LED directly without a resistor, but as a rule you never want to hook up an LED by itself, regardless of voltage.
