LED Wiring
hey,
__________________just wondered if i bought some led's how would i go about wiring them in my case? i imagine it would involve running wires from a molex connector but which ones and to where (short leg or long leg?) thnks to any electrical masters who can answer my question. rep available

it might be trickier than just wiring stuff to your PSU. You would have to find out the resistance of the LED's and add resistors to the wiring so not to run too much current through them...so you'll need a soldering iron and multimeter etc.

and the power in leds has to travel a specific path (unlike bulbs) there is 1 neg pin and 1 pos pin http://www.kpsec.freeuk.com/components/led.htm so attach the black -5 wire to the short pin and the red +5 to the longer pin (resistors may b called for!)

all around knowledgable

Well i am really know my stuff about wiring and eletronics; so anyway the average led you would find on the power light on the case is an 1.5 - 3.3 volt led there are many different types of led's in size and in voltage handleing if you decide to get a few small led's, and to lets say run them off the 12V rail on the psu, YOU WILL HAVE TO run them in series. In other words have 3-4 of them wired daisy-chained together one after another like bateries +-,+-,+-,+-,+-, (each one of +- indicates a led). Now if you are running only 1, or 2 in a circuit you might have to put a resistor in series of the led's to cut the voltage going to them so that they dont burn up on you.
__________________If you can post some details on what you are planning to do as a setup of led's i can assist you more in how to wire them up to work correctly.

ok ,well i did some research and it seems that the easiest option would be to run them from a battery seperate to my psu. prob a 9v battery for 2 or 3 led's. thanks for the help guys.

or you can use a power adapter...9V power adapters are very common.
