Urgent messages sent using Morse Code via radio waves or by electrical telegraphy are, by necessity, quite short – after all, you don’t want to spend all day dotting and dashing your way through War and Peace. These days, of course, if you want to send the latest piece of gossip or news to those near and dear there are quite a few quicker options – from email to instant messaging and Facebook to Twitter. For users of the latter networking platform who are looking for a novel way to merge the old with the new, Martin Kaltenbrummer’s open source Tworsekey Morse Code interface can deliver messages direct to the Twitter API via Ethernet LAN.
An Arduino Ethernet board takes care of decoding the dot and dash input from the vintage-looking Morse switch on top of the wooden box that encloses the circuitry and the 9V battery (although it can also be powered via a 5V mains adapter). There’s an RGB LED peeking through the side of the box for visual feedback, and a piezo buzzer that sounds when contact is made on the Morse Key.
