I built this On Air sign to help let my family know when pants are required to enter the room. I made the CNC out of walnut and maple. I cut the sign part on my CNC and put white acrylic behind it to defuse the RGB LEDs.
I can turn the sign on or off via voice commands to Amazon Alexa. And finally last week I figured out a way to automatically turn on it by writing a C# app to detect a Zoom, WebEx, Discord and MS Teams Meeting by monitoring UDP.
And this video shows how I wrote the C# app to detect a Zoom, WebEx, or MS Teams Meeting by monitoring UDP.
This video walks through the woodworking part of the project. It shows how I built the case out of walnut and maple.
This video shows my full build process for making the sign.
