Scrolling tweets with a WiFi LED matrix

For his most ambitious build to date, [Param] thought it would be a cool idea to have a LED matrix display spitting tweets out via a WiFi connection. The build is now done, and we’ve got to hand it to him for a very nice build.

The build is based on an Arduino with a Sparkfun WiFi shield providing the network connection. The Arduino pings a Javascript app that pulls down tweets from The Verge and displays them on an 8×8 LED matrix display.

What makes [Param]‘s build so cool is its portable nature; the entire device is completely wireless, getting its power from a Sparkfun LiPower shield  and an apparently extremely capacious LiPoly battery.

With a rat’s nest of wires hanging out the back of the LED display, [Param]‘s build is crying out for a proper enclosure, but even given that it remains a quality project. You can see a video of the WiFi’d Twitter display after the break.
