Anthony Marsico's Modernized Take on the Telegraph Turns Morse Code into MQTT Messages - Hackster.io

TL;DR

Anthony Marsico, a ninth-grade maker, has modernized the classic telegraph by creating a 3D-printed version that connects to the internet and transmits messages via MQTT (Message Queuing Telemetry Transport). This project retains the iconic Morse key for input but replaces the bulky design with a compact housing that includes a small OLED screen for displaying messages.

Why This Was Curated

The article presents a practical project that bridges hardware and software by modernizing the telegraph to use MQTT, making it highly relevant for software developers interested in embedded systems. It is accessible and actionable, providing a clear example of how to integrate coding with hardware, though it could benefit from more detailed implementation steps.
