Computer controlled light cube

led light cube

[Alex Hornstein] was bored one Saturday and decided to do something with the large pieces of scrap acrylic he had found. He built a cube and attached 15 RGB LED clusters along with 4 GB LED sticks. It takes 50W of power. The controller is built from ATmega48 and is controlled via serial commands over a wireless link from Spark Fun. You can find schematics, pictures, and video on his site, Art is Wrong.

    Is it just me or does everyone seem to love anything that uses LEDs and cycles through colors?

    Its like such a stupidly simple thing but so infinitly intresting, like a lava lamp.

  6. Is there a flickr or something?
    Well anyways, the next step is to put a computer in it.

    This isn’t a hack. It is somthing found on . What happened? Where are the hacks? The only thing that is appearing now is just how-to’s.

    I miss the old hack-a-day stuff, And I foush these manufacters would make their stuff a little more “Hackable”.

  9. Join team hackaday, click my name, we’re hoping to roll out a number of hacks this summer.

    is it just me or are the hacks getting lamer and lamer?

    It’s not a lame hack.
    I think the wiring could have been done neater or at least less obtrusively, and the photographic effects were annoying.
    -but a big box of lights is always cool to have around the house!

    That’s waay too much power-LED’s hardly use that a misprint?
