This is an easy way to drive a lot of LEDs-- up to 625-- in a big matrix. You can make an LED sign for your window, a geeky valentine for your sweetie, one bad-ass birthday card, or freak the holy bejesus out of Boston. Your call. It's a versatile, high-brightness display.
The display can run off an AC adapter or batteries (3 'D' cells), and is designed to run as many green/blue/white/violet LEDs as you care to solder into the holes, all with excellent brightness. The board can accommodate LEDs in several common sizes: 3mm, 5 mm (standard T-1 3/4 size), and 10 mm. A photosensor is provided that can automatically turn off the display in bright daylight or incandescent light.

I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
