Ditter is a telegraph key that posts to Twitter. The project uses an Arduino microcontroller and was a collaboration with Jason C. Reed, who wrote the morse code parser. Ditter was shown at 937 Liberty as part of the Rossum’s shows “Robot Resolution” and “Signal to Noise Patio,” for Pittsburgh First Night and a Gallery Crawl in the Cultural District, respectively. You can read Ditter’s posts (some of which are much more coherent than the others, naturally) at twitter.com/ditter.
