Do you find Morse code communication options limited? Check out [marsPRE]’s WristMorse communicator, an open-source device that connects via WiFi, can function as a Bluetooth keyboard, and serves as a Morse Code training tool.
Using the M5StickC Plus as the base, [marsPRE] adds a custom “hat” with a 2.5 mm plug for radio connection and two touch paddles for Morse Code input. The attachment, enclosed in a 3D-printed housing, plugs into the M5StickC Plus through an eight-pin header.
With the M5StickC Plus as the hardware foundation, [marsPRE] focuses on software development offering training, communication, and Bluetooth keyboard functionalities. The touch paddles facilitate semi-automatic keying, with one paddle for long dashes and the other for short dashes.
Drawing inspiration from Morserino-32, [marsPRE] shares the open-source software for the wrist Morse code trainer on GitHub for those interested. Morse code, though an older communication method, retains value. You never know when you might need to send a message discreetly or decode spoken Morse code.
