    ok, so i got these 4 redundant cold cathodes sitting here.. curious as to attaching them to the pcb edge of a graphics card (or 2 in sli ;)) will cause the cards any harm or interferance?

    any idea's i mean i know cathodes have a VERY high voltage going through them to make em glow, thus i don't wana fry anything...
    anyone tried this?
    they're like the perfect length so it'd look pretty kickass lol

    Haven't tried it...

    But I've painted the edges of my cards with UV blue paint and they look awesome.

    Would think edging a card with UV rods would look pretty pap. Not sure whether it would be danergous or damaging.

    I've got loads of spare blue UV paint if you want to borrow some?

    they're just normal ccfls, not the uv ones :S the edges kinda already glow from the pcb...

    don't know
    cheers for the offer thought i'll keep that in mind

    Iv dismantled 2 of mine to put them in my rad case.......I have just wrapped it in a single piece of clear selotape, and i can touch them with no shock.

    I see no reason why you would have a problem ;)

    hmm, what about e.m. interference?
    they're only the glass tubes as it is.. theres no plastic cylinder like with the ones you buy normally.
    meh i'll try it later and see :)
    thanks for the heads up tho neil

    interference...no idea

    Yeah mine were the normal ones that come in the plastic tube...ones you remove the cathode from the plastic cover there is a wire that ran down the length of it, which is what i taped over.


    So whats the diff between the normal and the glass ones :confused: never heard of glass ones

    Hey sub.

    if you are worried about interference, then why not ditch the cathodes and just secure el wire to it? They are thin, easy to work with and very tidy. They also emit a nice bright glow :)

    The cathodes are fine. It's the inverters that generate interferrance.

    You can touch cathodes safely. The plastic tube is to protect them from snapping and such.

    They are VERY flexible TBH... and one great thing about them compared to cathodes is you can snip any part of the EL wire and re-attach it (say to shorten the wire for example), and it will still work
