‘On Air’ Light for Microsoft Teams and Zoom Meetings

Back in the 90’s, the 1990’s, I used to be a late-night radio show host on Froggy. I was known as Jeremiah Bullfrog. When I left the radio business to start my own software company, Troy, the head engineer, gave me a parting gift – an ‘On Air’ light. Our company had remodeled and consolidated studios and lots of surplus gear had accumulated. I had the On Air light on my office shelf for over 20 years. With the recent events, I came up with a project to put the On Air light to use.

Along with the rest of the world, I have been working at home for the past couple of weeks. All of my meetings are now online/virtual ones and we use Microsoft Teams and Zoom. We also use video to better facilitate a connection and help us focus on the meeting. The camera that I have doesn’t have a light indicator showing whether it is in use. So, I put two and two together and come up with a remote controllable ‘On Air’ light for online meetings. It was the perfect project to entertain my three-year-old for a few hours. He was delighted every time the light turned on.

George and I ripped apart a Sunbeam Touch Light that I got for $1 in a surplus sale. This light had a strip of LEDs, a controller, and a power supply. I just added an ESP8266 module and connected it to ThingSpeak using my tutorial that I published a few years ago. I wrote a little Visual Basic.NET script based on a project that I found on CodeGuru to detect whether or not the webcam was in use or not. If it’s in use, the script sends a signal to ThingSpeak to turn on the light.
