Introduction: Awesome LED Computer Mod

I am putting this in a computer mod I am making.

Yeah, It's not finished, the panels aren't actually glued down and I don't have a circuit for it yet, but I thought I'd let you guys preview its awesomeness.

Hmm, I just realized I glued the red LED on the wrong side on the top.

    I made it!
    But it does not look good in a pc case.

    Cost me around $150

    I have alot of questions.
    How thick is that Plexiglas?
    What is that blurry thing you put on the surface? What is it called?
    and When are the instructions going to come out. Because i cant wait> :)

    Hey, have you completed it yet im really interested in getting a copy of the image could you post it up so can copy it

    Thanks

    When are you going to come out with the instructions to make this?

    very nice :))

    would this be for a laptop?

    have you thought of using a tricolor led? not the ones that go through a loop, but the actual 3 annode and 1 cathode leds? it sure would save a little space, though it would mean more programming/switches =/

    no more programming than this would take, just connect the anode leads from each individual LED to the corresponding color anode leads on the tricolor LED and the cathode is common between them, all you'd need to do is figure out appropriate resistor values.

    in my diagrams i have dimmers (rheostats) for each individual color and a master dimmer, determine appropriate values for each and you have two leds done, same would work with more, but i got tired of paint.

    Can you give me a bit more info on this as I love the project but sounds like this might improve on it. My electronic expert score is -2/10, so go easy. If you have an URL to show that would be great. THX

    Indeed you could, but then there would be a cord running out of it. So it would be less portable, but wouldn't run out of charge.

    perhaps rechargeable batteries via USB?

    The last picture in the slideshow looks like theres some piece of paper on the plexiglass. Is it to add to the effect?

    I believe he used it to defuse the light more evenly.

     very creative way to adapt the led cube to a pc case

    I would like to see someone make one where the light travels. maybe all starting in the center and traveling to the edges.

    You'd probably need a lot of LEDs, and some kind of processing unit to switch them on and off at the same time. It is possible though

    or the right set up with a couple of capacitors. that way the capacitors have to "fill" with electricity before they will light up. it produces a flashing system. only problem is that they require more power, leds, and space.
