    Presenting the Wearable Morse Code Instructor with M5StickC

    If you’ve ever thought that the alternatives for Morse code interaction were too restricted, explore [marsPRE]’s publicly available WristMorse transmitter. This innovative device can establish a WiFi connection, serve as a Bluetooth keyboard, or function as a Morse Code tutor.

    [marsPRE] has utilized the M5StickC Plus as the central component and added a unique “headgear” featuring a 2.5 mm jack for radio connectivity and two touch-sensitive paddles for Morse Code signaling. The extension is encased in a customized 3D print design that hangs from the edge of the M5StickC Plus, linking the headgear via an eight 0.1 inch pin header.

    By leveraging the M5StickC Plus, [marsPRE] can concentrate on the software aspects, delivering diverse training options, communication features, and enabling the device as a Bluetooth keyboard. The pair of touch sensors offers a semi-automatic signaling method, utilizing the upper sensor for prolonged dashes and the lower sensor for brief dashes.

    Deriving inspiration from the Morserino-32, [marsPRE] has transformed the wrist Morse code instructor into open-source software, accessible on GitHub for those interested in exploring it. While Morse code may be regarded as a traditional encoding technique, it remains a method deserving admiration. One can never predict when the need to transmit a message via dreams or translate spoken Morse code might arise.
