WHY THE "bad words" CAN'T THEY STICK TO THE SAME COLORS???!!!

I found my old Logitech Marble Mouse and started finding stuff for making a trackball-fan-mouse-projekt
(taking lots o' pics, so I can make a mod guide :wink:)

BUT!!! I came across a little problem... (since I aint got a multimeter-thingey, YET)
The weird problem is: The ps/2 cord is connected to the pc with six wires
(I checked www.howstuffworks.com)
but inside the mouse there's seven
(a big black one, an orange, a thin black, a green, a yellow, a pink! and a red)!
I also read that only four of the six wires was used!!


ALSO!!! (a fan question)
on top o' the cute little fan it says: "12V 0,11A"
Does'nt the little rodent only spit out 5V?? does that mean it'll go slower??

Please help a little welder

The black is most likely ground. Put the black lead from your multimeter on the black wire and the red on one of the others until it reads 5 volts. Since you don't have a multimeter the red one is most likely +5 volts. I wouldn't do anything without testing it first. Yes the fan will spin slower. That's fine. You wont want a high powered noisy fan in your mouse. But if you really do you'll have to takie power from uotside the mouse.

Someone submitted this photo to me and asked what were the +5 and gnd lines. Thin was gnd and red +5 in this case.

Getting that 12 volt fan to even start up with 5 volts can be tricky. You are better of by looking for that 5 volt fan and not even bother to try this 12 v version. sorry.

edit: hehe, posting that image for this message could be a good thing. :) here goes:

most fans will work at 5v, hook it up to a test psu to the 5v line and find out.
