8×8 RGB small form factor toy

Here’s a cool tip, sent in by [Martin]. He has put together this very compact package for an animated 8×8 RGB LED array with a tiny footprint. It is controlled by an ATMega16 powered by 2 small lithium cells. While it may not be quite as small as the space invader button, it seems to have a bit more animation horsepower.

    it’s RG, not RGB

    It looks very well done. I like it.

    It looks ugly when there’s just one pixel on a row. But it’s compact alright.

    where’s the ardunio/twitter?
    anyway, it looks useful and better than anything I could do.

    Check out my own RG matrix. Uses an Atmega8, TLC5920, and MAX232

    It can do text scrolling, frame transition effects (scroll up/down/left/right/dissolve) and frame streaming from a host device (microcontroller or PC).

    It’s a fully functional PCB with level-selectable serial (TTL or RS232) via jumpers and a typical AVR ISP connector. All communication is done via serial, but the device can easily be programmed to run by itself.

    Built with an Atmega8, TLC5920 Matrix Driver, and MAX232.

    Oh yeah, someone made a nice animated puzzle out of these displays. Google for PuzzleMation.
