Pi Matrix

A very quick post: I’m about to run out of the door to meet TechCrunch at Adafruit. Have a squizz at the video below; this is a really cute little add-on for your Pi that’s just been put out by w8bh.net. It’s an 8×8 matrix of LEDs that you can plug directly into your Pi’s GPIO and program to do neat stuff. You can buy one at mypishop.com. Discuss it among yourselves – I have to go and jump in a taxi!

Build a 3×3 one myself, planning on building a 8×8 one. I think LED matrices a very interesting.

I noticed the LEDs went the same direction. I wondering you could have LEDs going both left and right simultaneously? This is very neat though. I may get one just to find out for myself.

Whizy? Surely that should be xyzzy. Well, ok, since it’s the Pi “Matrix” rather than the Pi “cross product”, I’ll let you off…

the video just sold me! now if I can put it together properly when it arrives smoke will not be one of the special effects!

I excepted there to be a let matrix display that is a bit bigger than the pi itself. Then there would have been a few of the pis with the displays forming a “pi matrix”
