    Hi every one i have recently started a new project the led cube.:D
    But the problem is that i don't know how to program it and i don't want to do it. Is there any other way so that i can get some kind of pattern in my led cube.
    thx in advance.

    As in "i don't want to do it", does this mean you want someone else to do it for you?

    LED cubes are usually driven using a technique known as "Charlieplexing", named for a Maxim employee. Do some Google searches on Charlieplexing, and see if you really want to try to build something like that out of logic IC's instead of a uC.

    Your hardware requirements will get REALLY large in a big hurry unless you use a uC. They'll need a big truck to make the delivery.

    So, you have a new project that you don't want to do. Is that right? Is it a school assignment? How much are you willing to pay to have someone do it for you?

    Just wire each LED to a SPST toggle switch. Mount all the toggle switches under the table so people won't know you are switching them.

    Just buy a bunch of flashing LEDs and you'll get some sort of random patterns.

    Fry's was selling them off the shelf. You could probably mail order it from them, since they have a online catalog.

    I was serious. Unless you plan on using some form of programmable logic you'll have a difficult time setting patterns.
