    Large indoor pixel-art display frame

    Hi all,

    Just playing around with an idea for an indoor art piece. I'm a fan of 8-bit art (who isn't ), and instead of printing and hanging on the wall, I'v been toying around with a large matrix display.



    I'm thinking 256x384 pixels (the image above, by Waneella, is similar at 270x405) - this is 24 times 64x64 panels, 4 wide, 6 high (similar to these). It'd be around 0.8m x 1.6m all up.

    I currently have two main issues with this:
    • Power consumption. Looks like it'll be consuming around 400-500W. Eek!
    • Brightness. I think it'll turn my living room into an airport runway.


    Any advice on alternative displays? I really want to build something from large individual pixels rather than wham a monitor on the wall and call it done, but I also don't want it too bright or power hungry.

    Cheers,
    Peter

    I guess I could find some very low power RGB LEDs and wire up each pixel individually. However I think I'll be dead before completing all 100,000 pixels
    At an estimated ~15 minutes a piece, that's 25,000 hours of soldering and circuit building. Or 12 years solid of 40 hour weeks, with no holidays!

    Any alternative ideas welcome! Anyone?

    Great job Would this work on the HU with the EQ?
    This is the unit I have. Sometimes the display is completely off.

    Aside from the sheer number of LEDs, the tough part about LED pixel art is eliminating the light bleed from any LED to its nearest neighbors. Every project I've seen do this well has highly visible dividers between the LEDs which make the display look like a checkers board where the individual squares light up, but you still see a visible dark border between them.
