I can't seem to figure out why my lights won't light up. I did not have a pass through molex connector on hand so i made one:

And here is how I connected it to the xbox:

umthat soldering looks pretty sad... if you put like a six volt battery on the connections do you ge light??? if not it might be the soldering or the connection. There could be a lot of things wrong, the molex could be fine for all we know.

~edit : spelling

does your hard drive work? Then your molex is fine. From the looks of your soldering job it looks like the soldering will be the problem.

do the lights not work at all? if they don't work while the top is on the xbox make sure the wiring is not touching any metal. also check that no positive wires are touching negative ones and that you don't have any leds backwards.

good point, but i dont think that it is. if it was a short, then the hdd wouldnt spin up

did you even check your resistor size? that thing is petetic.... it might be just that you dont have enought power going through them.

Its pretty hard to see, but judging from the pics ; You are using 12 volts , you are using 1 resistor to light up all those LED's. A resistor can only let a certain amount of power go through it, Im guessing you used a 1/4 watt, with the bumber of LED's you are using im guessing that you are using more than 1/4 of a watt.

Next time , use the 5 volt line and make sure you dont use a resistor for more than a certain amount of LED's. (use metku calculator).

lol, ya ive been working with resistors a lot latly especially in autos so ya.... looks like a 10 ohm 1/4 watt....not that i can tell the colors all that well with your pic -.-

try 5v and either 3 220's or 1 with less resistance
(btw when i say 2 or 3 220's i dont mean in a line... i mean split it up)

ot just use a led resistor calcuator and get teh right one. a hell of a lot easier.

but i think his problem is the polarity of the leds
