A while back, I created a web app to allow people to transmit Morse Code messages over the web to each other. It works by listening for button presses, and then alerting the server to distribute an audio file to all of the clients connected to the server. It's built on Node.js and Sockets.io.
It's currently available on the web at https://morse.nomik.xyz. The code behind this project is available at https://github.com/Nomikxyz/MorseCodeChat.
Let me know what you think! It's certainly not perfect, so I'm open to any contributions!
