    k
    i took a cold cathode bulb out of my scanner, and the thinger it plugs into but im not sure if its an inverter or not (because apparently u NEED it to run :p
    this is what it looks like

    now, how would i go about hooking this upto my case? 12v or 5v?

    That looks like an invertor. And it would probably be 12v.

    look at the adapter the scanner used to plug into the wall, if it said 12v, you're good! If there is no adapter, that scanner was doomed when you bought it :lol:

    wholey booyow batman
    its a 12v inverter and i LOOVE it :lol:
    its the whitest light ive ever come across :eeek:

    is it possible to hook 2 cold cathodes upto 1 inverter

    Bee, I don't beleive you can do that. There have been numerous posts about it and the general feeling is that you need two. I suppose you could rig up a switch so that only one is on at a time if you hooked two up to one inverter, that might work.

    I don't think that the designers of that scanner designed that inverter to stand the power of that cc!

    You could probibly design one, but almost every cc you buy comes with one.

    heh, ive got this whole board thinger here that the cc plugged into, but its got the lens and other **** for the camera, as well as the camera itself on the board, and onna those ribbons just plug into it, if i can determine +ve from -VE on the ribbon i could get it to work with its own inverter couldnt i?

    It probibly could run on it's own inverter, but I think you would be better off with what you're using!

    Now, come here, my little elderly scanner, you have peices I desire...

    uhh
    i have 3 cold cathode bulbs, all jacked from scanners, one has an inverter, and one of them has a inverter built into the board...the board is about 1.5"x5" and i dunno where +ve and =ve are for a ribbon connects to this board, how do i go about finding out?

    I don't think that you could use one inverter for all that. I know an engineer, and you want it to barely work. As my wise father says, anyone can build a bridge, only an engineer can build a bridge that barely stands!

    Man, I just threw away that dead scanner! Darn, knew I should'a kept it!

    Oops, sorry. Didn't get much sleep last night :lol:

    How was it hooked up? What you do, is you take a voltmeter, and set it to beep if it detects a short. You stick one lead on the in voltage from the wall outlet, and start probing the contacts with the other (with the scanner unplugged from the wall, of cource).

    If that is what you man by +ve and ve, this should work. If not, let me know (and I'll whack myself on the head again to spill out the awnswers).

    Insulate those leads. They are at least 100 volts. One thing to help, ground traces are usually the large ones.

    Once again, you're right. I know neon inverters are about 115, and ccs are prety similar, I think.

    actually i did some checking, the usual CCFLs weve been putting in our cases have something around a 1,200 volt startup, and around 600-1000 operating range.. seems to be about average..

    just tested my research.. a little above what ive read..

    [​IMG]


    brings me to my question, i cant locate this kynar wire, nor can i find anything suitable for that voltage, best i can do is 600volt wire, but what would be better for less leakage, solid or stranded?

    Leakage? I think solid is what they use for the mains in your house, so gust get thick solid wire (16-12 g), and that should do it!
