Re: What happens when a bored EE gets ahold of 57,600 LEDs
The LEDs are the standard 0603 size, 1.6mm x 0.8mm. They are made by Kingbright, and come on reels. I bought 22,000 of each of R,G and B types. Surprisingly, green costs twice as much as blue.
This display runs at much lower power than a typical LED billboard, since it's designed for use indoors or at night. Curiously, the idle current of the 1,000 driver chips (15mA at 3.3V) uses as much power as the LEDs themselves.

OMG that is awesome! Although the phrase "too much time on your hands" comes to mind...
Now to connect video cameras that show the scene 180 degrees from the LED, making an effective invisibility

This is definitely one of the coolest things I have seen recently.
The Lampduino I am building pales in comparison. I have a measly 8x8 grid! Last edited by Bryan Herbst : 07-07-2011 at 21:13.

So.... I want to write something snarky about the suit Will-I-Am wore at the World Championship, but I'm fighting the urge.
Perhaps next year's championship's entertainment should feature Squirrel's brother?  Blake

Heard about it again on the radio yesterday (the hosts called it "nerd cool"), and it is featured on Engadget today!

57,600 LEDs cost a lot of money, even if they're only a dime or a quarter a piece.
The flex circuit boards and automated soldering are also expensive. But the real expensive part is the six months it took to figure it all out.

neat! It's all over the tech/geek/nerd blogs. Interesting about the batteries, everyone is so concerned about battery life...he has 5 sets of batteries for it already. They fit in your pockets, one on each side.
