On Air Sign

Amazon Echo controlled LED sign

I made this on air sign out of Walnut and Curly Maple with RGB LEDs that I can control via Amazon Echo to let my family know when I am on a video call. I also created a windows desktop application that can detect when I am in a Zoom, WebEx or Microsoft Teams meeting and automatically turn on or off the my sign. Check out my YouTube video below for the full details of how I built this sign.
