Maverick923 Posted September 23, 2021 Report Share Posted September 23, 2021 I have a few of these LED pcbs for the OG Xbox controller ports. I am trying to locate a tutorial on how to install these, but I cant find one. Can anyone please point me in the right direction. Quote Link to comment Share on other sites More sharing options...
SS_Dave Posted September 23, 2021 Report Share Posted September 23, 2021 Is this what you are looking for. You select the value of the resistor depending on how bright you what them, If the led's don't light up you have them backwards.

That would also be very helpful. Quote Link to comment Share on other sites More sharing options...

Like this, You remove the metal casing solder the completed PCB to the red/black with the LEDs facing away from the wiring. After you have tested it you can then refit the metal shield.

I could not find this info anywhere. Someone sent them to me and was like oh cool, I wish I knew exactly how to use them. Quote Link to comment Share on other sites More sharing options...
Maverick923 Posted September 26, 2021 Author Report Share Posted September 26, 2021 Looks like I got some bad info about the LEDs and resistors that are just way too small. Which size should I use? Quote Link to comment Share on other sites More sharing options...

Which size should I use? What type of problem are you having with the LEDs? Which LED and resistor value did you use (part number of the LED)? Online LED Calculator - Current Limiting Resistor Calculator for LED(s) What are the specs of the LEDs you installed? Need to know their forward voltage drop (Vf) and maximum current rating. Generally, an LEDs Vf value is 2 Vdc and the maximum current rating is 20mA; however, not all LEDs have the same exact specifications. Vs = Vf + I(led) * Current limiting resitor value For example: 5 Vdc = 2 Vdc + 20 mA (0.02 Amps) * R Ohms (5 V - 2 V)/ 0.02 Amps = R R = 150 Ohms However, using a slightly larger resistor value is better to keep the current flowing through the LED below its maximum rating. NOTE: If you install the LEDs the wrong way around, they will not light up. Quote Link to comment Share on other sites More sharing options...

If I sneeze, they will be lost for sure. Quote Link to comment Share on other sites More sharing options...

The led's and resistor are the other way around so the Led's are on the edge of the PCB So the leds are the red circles and the resistors re the blue circles The leds can be 1608 (1.6mm X 0.8mm) https://au.mouser.com/c/optoelectronics/led-lighting/led-emitters/standard-leds-smd/?orientation=Top+View&series=1608 The resistors you could also use 1608 Cheers SS Dave Soft modding is like masturbating, It gets the job done but it's nothing like the real thing.

MadMartigan Posted February 1, 2022 Report Share Posted February 1, 2022 (edited) I have lots of these. I used 240ohm resistors last night with 3mm leds intended for 3V drop at 20mA. They were not very bright so I ordered 100ohm resisters as advised by the calculator at ledcalc.com I used 240ohm since I already had some. Am I wrong in that the 100ohm resisters will make the leds brighter? Edited February 1, 2022 by MadMartigan Quote Link to comment Share on other sites More sharing options...
SS_Dave Posted February 2, 2022 Report Share Posted February 2, 2022 Yes a 100ohm will make the LED brighter If you put 240 ohm resistors in parallel then you will get 120 ohm Cheers SS Dave Soft modding is like masturbating, It gets the job done but it's nothing like the real thing.

Bowlsnapper Posted February 2, 2022 Report Share Posted February 2, 2022 Now THAT is a nifty product. Kekule made that? I'm assuming they're no longer in production? Woulda' made those LED installs i did a bit cleaner back in '05. Quote Link to comment Share on other sites More sharing options...
MadMartigan Posted February 3, 2022 Report Share Posted February 3, 2022 Yes Kekule made the ones with the SMD LEDs. The kind in my picture are for one normal 3mm LED. Quote Link to comment Share on other sites More sharing options...
