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.
