    -All, any...

    I've just ordered some EL wire to spruce up my Quicksilver (the smooth, clear handles beg for it) and I have a question.

    According to the power supply label, there are several power busses, what I'm interested in is the 12v bus so that I may use it to power the EL wires.

    Which bus(s) are powered with 12v? My guess is the drive busses, but then again, that's a guess.

    Can anyone advise?

    Oh, BTW- is there any interest in a picture once I get it done? If so, I'll post it.

    i have no idea what bus you want, but i am very interested in seeing pictures! i'm sure MacSnaps would love to have them posted there as well...

    i've often thought about illuminating my quicksilver behind the plastic side panels because i noticed that light does show through them.

    Actually, that's similar to what I have in mind. I ordered two EL wires from FrozenCPU to be placed around the outside of the aluminum hard case, just under the lip of the outer decorative paneling on either side of the tower. This would cause the wire to become exposed as it passes under the corner handles. It's a pretty easy mod, all I have to do is drill little groove-guides at the base of the ovular structual supports of the the clear handles so that the wires run directly under them (I could go around the ovular structures, and drill no groove-guides, but I want the light to travel into the handle acrylic as much as possible for effect).

    All I need to know is where inside I can plug the power units into.

    The power units use molex connectors just like those on the HD power bus - ergo my assumption.

    Get a multimeter, even if its a cheap one.
    Always verify the power taps.
    They may be different than labeled or very from spec.

    -Thanks vniow

    Ok guys, here it is. I actually did this in under and hour with no holes drilled and only one little piece of scotch tape.

    It's nothing very involved but here you go.

    Oblique angle.

    looking good. personally, i'd also like to strip the outlines for the optical drives and speaker, drop some line in there, too.

    patrick-
    that looks really cool. how much cable did you use for it? and did you use the sound activation module? i'm really interested in doing this to my quicksilver. any tips would be appreciated...i'm looking into that manual that vniow posted right now...

    thanks

    I was really surprised how easy this mod was to to, and I'm glad that it is completely reversible with no permanent alteration.

    I ordered two wires, each was 5 feet long and came with their own inverter with the sound activation setting, so yes, I can flip the switch.

    However, I am using only one inverter as it is a double header, to power both wires. I also used the entire length of both wires.

    -I had to do some jury-rigging as I didn't have a free MOLEX connector (I have three hard drives). Here, you can see the 'piggybacking' I did by popping off the back cover of MOLEX P5 and insering the inverter power wires.

    Wires highlighted...

    -Here is the inverter, switch out so that changing it over to sound-sensitive is easy.

    Note that I mounted the inverter in the useless space above the CD drive. You can see the power wires from MOLEX P5 leading to it on the left.

    Inverter highlighted...

    -Here's the big one.

    This entire mod is held in place by tension - mostly at the corners. Tension is important to keep the glow consistant. If there is a slight bend the lighting may not be as bright.
