This kind of homemade USB plug could also be used for other things, like repairing USB cables.

I used a 1k resistor because I just wanted a nice looking light, not a blinding one. ;P Feel free to use a different value if you choose.

you'd be unable to remove it, if you don't attack a string <.<
Just sayin'.
(i.e. on the left, not on the right) and it still works great. The 1k ohm resistor makes it a little dim though. I might use an 18 ohm resistor (cos' a lot of other ibbles' use em').
Do you know how you can figure out which way it goes?
Like lets say there are colors WXYZ.
The resistor is eithe WXYZ or ZYXW, how can you tell?
(In the image, is this the resistor you're using?)
no, it does not matter if the resister comes first or the LED
and you read resisters from the band that's closest to the end toward the gold ban (sometimes silver or wide-stripe brown)
these are brown, black, orange, gold = 10 K ohms with a ±5% tolerance
But, in electronics, it is said that they flow from positive to negative, so as not to be confusing.
And again, it does not matter if the resistor is hooked up to the positive side or the negative side.
Thanks, that helps a lot!!! :-)
