In his blog, Marc from Robot Dialogs presents a very nice hack involving a IBM Selectric II typewriter: by means of an Arduino board and several solenoids, the typewriter can be successfully connected to a computer to emulate a vintage teletype.
The complete story can be found here, together with several videos about its development.
