“Should you answer a rhetorical question?” But anyway, the answer is that you can never have enough LEDs. At least that’s what [Adam Haile] at maniacallabs seems to think. So far, he’s up to 3,072.
We’ve reported on a previous big-LED build of [Adam]’s before, called the “Colossus”. And while this current display is physically smaller, it’s got a lot more LEDs. And that means a lot more, well, everything else. Weighing in at roughly 500W when full-on, with 175-part 3D printed frame and diffuser elements and driven by three Teensy 3.2 microcontrollers driving shift registers, this display is capable of putting out 60 frames per second of blinding RGB LED goodness.
The designs, adapter boards, and animation code will be posted once they’ve “had a chance to clean things up a little”. Here’s hoping that’s soon! [Edit: Code and designs are here. Thanks Adam!]
If you’re in the greater Washington DC area, you can even swing by the NoVA Maker Faire in Reston to check it out in person. If you do, tell ’em Hackaday sent you.

This furry Halloween decoration proves to be a simple build, but it’s still quite popular with the little ones. [Chris] had a Halloween party for a group of 2-5 year olds and this monster that peeks out of a box was a huge hit. The trick really isn’t in the complexity of the build, but in the interactivity.
The enclosure is just a shoe box which has been covered in synthetic black fur. The lid was hinged on the back, and a hobby servo with a bit of an extension on the arm is used to lift the front which reveals the monster’s paper eyes. Inside you’ll find an Arduino, breadboard, and battery pack. It’s not visible above, but a distance sensor on the front of the box is monitored by the Arduino. When it detects something in front of it the servo fires up and pops open the lid. The firmware includes a timer so that the monster waits a bit before taking its next peek at the party.
Over 100,000 Lego pieces, 4 people a year to create, and a 12 foot by 12 foot chess board make this the largest most awesome Lego hack we’ve ever seen. Take that Lego Printer.
For a mere $30,000 you too can have such a setup. Not a lot of information is out yet, but we do know all the pieces are remote controlled via a PC with LabVIEW and a total of 38 NXT controllers are used. Oh, and of course you can see it live at the 2010 Brickworld. Check out a video of a replayed game after the jump.
