Giant Scrolling LED Sign Powered by One Arduino Costs Around $15/Foot

parallel bit-banging eight NeoPixel strips from one controller, this time around josh.com shows how to build a giant scrolling LED sign, for about $15/foot using similar materials. That’s pretty cost effective for the results:

Would you do with a massive full color animated LED display? How about…

  • Read your Tweets in giant 140 char gulps from a block away
  • Add English sub-titles to the Eiffel Tower
  • Display a live-updating, 45 digit long countdown of the number of atoms left in the known universe

    •  
    What if you could build the display however long you needed it, for only about $15/foot?

    What if it was really easy to build and used everyone’s favorite low cost micro-controller so you could easily change the software to do whatever you wanted?
