does any body know if its possible to put lights on an xbox or how to wire them?

treemty · « **Reply #1 on:** September 17, 2009, 12:54:01 PM »

Yes, of course its possible, you just need to know what type of resister to have. Which also depends on how much voltage your leds can handle.
Ill give you a link to the soldering point if you answer this one quick question for me.
Do you want the leds on ALL the time? or only when the console is on?

Blazinkaos · « **Reply #2 on:** September 17, 2009, 09:24:54 PM »

Now then like treemty said yes you can but my questions where exactly are planning to place these leds such are you referring to swapping the power leds or adding leds to the inside.

i wanted to put them on the inside

scott · « **Reply #6 on:** September 17, 2009, 11:05:22 PM »

Dosnt answer how many you want, of what kind,

lookkool3 · « **Reply #7 on:** September 17, 2009, 11:31:53 PM »

maybe like nine or less aslong as their bright its good and is it possible to make them flash or fade in n out or something with a chip?

What we mean by "what kind" we mean, 3mm, 5mm, SMD etc
and yes you can use either a pulsevu or a fader if you wish

im trying to do something like this what size do you think would be good because im not that familiar with all the different sizes i have some 0805 leds but thats just too small

treemty · « **Reply #10 on:** September 18, 2009, 12:42:01 PM »

Those are more than likely 3mm

Blazinkaos · « **Reply #11 on:** September 18, 2009, 03:05:44 PM »

3mm or 5mm should do just fine then.

lookkool3 · « **Reply #12 on:** September 18, 2009, 05:16:17 PM »

ok ill take 3mm do they sell them on ebay?

Blazinkaos · « **Reply #13 on:** September 18, 2009, 06:07:56 PM »

Oh yea pretty much anything can be found on ebay.

lookkool3 · « **Reply #14 on:** September 18, 2009, 07:09:13 PM »

ok but what about the whole wireing and soldering points wasn't somebody guna help me with that or can i find that on ebay too

Yeah, let me go grab those for you...
Admins, please dont get mad at me for this, but we dont have these pinouts here yet(we do, but not as detailed)

If you have an old VGA cable laying around, tear that beast open and you will find a good 9 different colored wires that run the length of the cable. Excellent source of free wires.

Just solder in parallel and connect to either a 5v or 12v source. When you get that far, Ill grab you a pic.

50, 3-5mm leds are on ebay for $4 shipped.

lookkool3 · « **Reply #17 on:** September 18, 2009, 08:16:11 PM »

i have alot of 30 guage wire but im guessing thats just too small
i might have a VGA cable but im not sure what that is or what its for
BTW wont i get banned for takeing more power from the xbox ? like those fan mods

NVM i read that post i get it know

Blazinkaos · « **Reply #18 on:** September 19, 2009, 02:47:33 PM »

Yea i been realizing that the size does matter with what voltage you use so i would suggest 20-22 gauge wire when wiring them up. With that much current running through that xbox 30 gauge will over load the xbox then shut it down. I know from experience and my college courses i been taking. For example why you think electrical to power the a house is 2 inches simpley because around 10000 is simply being supplied through it any wire smaller then that will over load or it can also over load do to power over use. But enough of that got carried away. So yea like scot i believe wire from VGA would be large enough for this but other then try getting 20-22 gauge to make sure.

lookkool3 · « **Reply #19 on:** September 19, 2009, 05:31:10 PM »

ok now how do i wire it?

Blazinkaos · « **Reply #20 on:** September 19, 2009, 06:10:41 PM »

Well first you need to locate the voltage sources and do some calculation with your resistors in it.

lookkool3 · « **Reply #21 on:** September 20, 2009, 12:31:53 AM »

could u give me an example?

Blazinkaos · « **Reply #22 on:** September 20, 2009, 07:08:14 AM »

Ok well lets see there are many voltage points use most common on can be the power jack one under the mobo. Thats 12v there so depending how many leds your hooking up to it you can use certain sites to put in the info to figure your resistance that you need to add so your leds wont burn out.

http://www.hebeiltd.com.cn/?p=zz.led.resistor.calculator

Thats what i use to calculate the resistors i need. If you not going to use that many you can try putting in series but most commonly used is parallel.

lookkool3 · « **Reply #23 on:** September 20, 2009, 09:27:17 AM »

if i put them in a series wont they lose some power and not be as bright as if they were single ?

Blazinkaos · « **Reply #24 on:** September 20, 2009, 10:44:15 AM »

Not unless you put to many leds but i recommend parallel its works great for me.

Several people on these forums ask “How do I wire LEDs?” I decided I would write a brief tutorial so they will understand how to wire and the different methods of wiring. I will also explain the resistor calculator because it seems some people don’t understand how to use it. Let’s begin with the various wiring methods.

There are three different wiring methods. These methods are single (for one LED), series (for multiple LEDs) and parallel (for multiple LEDs). I am only going to talk about series and parallel circuits.

SERIES

[/b]
When wiring in series the voltage of the source is dispersed equally throughout all of the LEDs. In order to find out how much power will be going to each LED you divide the voltage of the source by the number of LEDs. In a hypothetical situation, we have a 12V source and 6 LEDs (each requiring 2V to run off of). Divide the voltage source by the number of LEDs and you will get 2V, which means that 2V will be going to each LED. Great, each LED works perfectly and has the required voltage needed to run.

What happens when you have 3 LEDs (requiring 3.7V to run) and a 12V source? You will have too much power going to each LED. Divide 12V by 3 (LEDs) and you will get 4V going to each LED. Because there will be to much power going to each LED you will most likely smell something burning and will have to go out to buy a new LED. To fix this problem a little thing called a resistor was invented. A resistor is a “circuit component which offers resistance to the flow of electric current. A resistor also has a powerhandling rating measured in watts, which indicates the amount of power which can safely be dissipated as heat by the resistor.” In order to figure out what kind of resistor you will need you will need to know several things about the LED and the voltage source:

A) What is the voltage of the power source?
B) How many LEDs will you be wiring?
C) What wiring method will you be using?
D) What is the voltage drop of the LED (How much power does it take to run it)?
E) What is the recommended milliamps (mA)?

Once you know these things you will be able to use a resistor calculator to calculate the resistor that you need (I will go into more detail about this later).

When wiring LEDs together in series you wire from the - leg on one LED to + leg on another (the longer leg on the LED is the + leg). Here is a diagram courtesy of LsDiodes that will clarify what I am trying to say.

If you place an LED backwards nothing bad will happen. The LEDs just won’t turn on. If you need resistor wire this into the circuit before the LEDs. Wire to your power source and a ground to finish up your circuit. Now your circuit is complete and your LEDs will work just fine. I would recommend using electrical tape or shrink tubing to put around your soldering joints to prevent a short.

PARALLEL

[/b]
Now on to a parallel circuit! A parallel circuit allows you freedom when choosing how many LEDs you would like to wire. Many people wire in parallel because of this “freedom”. This kind of circuit works great if you have a small voltage source and need multiple LEDs. If you had a 5V source and wanted to wire 3 LEDs (requiring 2V to run off of) there wouldn’t be enough power to power your LEDs. That’s true with a series circuit, not so with parallel. A parallel circuit works like so: “while every LED receives the same amount of voltage, the current of the source is dispersed between the LEDs.” What this is saying is that you will draw more power from you source. When wiring to a point on the XBOX 360 this won’t be an issue, only if you were getting your power from batteries or a similar power source that couldn’t replenish itself would you possibly need to consider this.

Because parallel doesn’t have any tricks for finding out how many volts is going through each LED I am going to skip to how to wire it. When wiring in parallel you always need a resistor. When wiring in parallel you wire the + legs together and the – legs together. Here is another diagram courtesy of LsDiodes.

RESISTOR CALCULATOR

[/b]
Now that you know about the various wiring methods I am going to talk about resistor calculators. In order to use a resistor calculator you need to know several things (I mentioned these above but here they are again):

A) What is the voltage of the power source?
B) How many LEDs will you be wiring?
C) What wiring method will you be using?
D) What is the voltage drop of the LED (How much power does it take to run it)?
E) What are the recommended milliamps (the desired current)?

Do you know this information? If so lets move on. I am going to be explaining everything from here on, based on this particular resistor calculator. Find on the page the wiring method that you will be using (series is in the middle and parallel is towards the bottom). Enter in the information that it asks (that would be my A,B,D,E). Double check the information that you have entered and hit “Click to Calculate”.

The information that you are looking for is this, the “Nearest higher rated 10% resistor” and also “Calculated Resistor Wattage” and “Safe pick is a resistor with power rating of”. When purchasing a resistor I look for a resistor that has an ohmage of the “Nearest higher rated resistor” and a wattage between the “Calculated Resistor Wattage” and the “Safe pick”.
