Doing it right with a morse code keyboard

Hackaday has seen dozens of Morse code keyboards over the years, but [Hudson] at NYC Resistor finally managed to give that idea the justice it deserves. He built a USB Morse code keyboard with the same type of telegraph key the pros use.

For his project, [Hudson] got his hands on a wonderful iambic paddle that is usually hooked up to CW rigs. Unlike previous Morse keyboards we’ve seen, [Hudson] used iambic paddles, a telegraph key with one lever for dits and another for dahs. Because the dits and dahs are separate electrical connections, it’s extremely easy for the microcontroller – a Teensy – to parse the Morse code and send the correct letter to the computer.

[Hudson] also added some audio feedback for the dits and dahs, and designed a laser-cut enclosure for the Teensy and speaker. Check out the video of the iambic keyer keyboard in action after the break.

    this would make it hard to play FPS!

    This would be nice for the blind, maybe.

    That’s the way it should be done.

    Have been searching all night and can’t find where to buy a Teensy in the UK. Where can I get a couple of these? Thanks
