Twittering pub hanging

There’s nothing groundbreaking about this hack, called the TweetWall, but the craftsmanship is gorgeous! [Yergacheffe] had access to the right tools; an epilog laser and a thermoplastic bender (an item we didn’t know we needed until now… thanks a lot). It has the usual bits you’d expect in a Twitter ticker, an LED matrix and an Arduino. There is also an OLED screen that displays the avatar of the current Twitter feed. Because data is transferred over a serial connection the SD slot on that screen is used to cache images which helps to keeps the messages coming without delay. The end product is quite good, we’d expect to see it hanging on the wall of the pub down the street.
