It involves a Morse code key, somewhat an old switch, with a new use in the form of modern Twitter. An open design exercise in interface archaeology, that decodes the input from a classic Morse key to send twitter messages.
The Tworse Key is a standalone device that connects through a standard LAN cable, the Morse signals are decoded by the built-in Arduino Ethernet board, which delivers the final message though the Twitter API.
Please follow @tworsekey on Twitter to read some example tweets sent from the actual device.
