ODD INPUTS AND PECULIAR PERIPHERALS: THE MORSE KEYBOARD

When it comes to rendering text input into an electronic form,the newest keyboards use USB for wired interfacing, while the oldest Morse keys use a single conductor. Shall the two ever meet? For [Matthew Sparks] the answer is yes, with his “The Gadget” Morse-to-USB HID interface which presents a Morse key to a computer as though it were a USB keyboard.

At its heart is a Seeduino Arduino clone, upon which the Morse key waggles a pin, and which through the extensive magic of software recognizes the keyed characters and converts them into USB key presses for the computer. It’s thus a surprisingly simple project, and the write-up spends far more time proselytizing the art of the carrier wave than it does on Arduino code.

Morse is simultaneously a manual art form, an efficient means of communicating through congested radio bands, and an anachronism, which probably explains its continued appeal in the radio amateur fraternity. We’re not sure how many keyboard warriors will switch to the single key with this project, but we can see that it might be a useful aid to learning as well as a pretty quick input method for the owner of an experienced fist.

Morse has featured in many projects here before, not least in this assistive Morse keyboard.
