If you haven’t heard, a lot of us are working from home these days, making mic and camera discipline more important than ever. To help avoid unwanted recording, Tovi Levis created the S.H.I.E.L.D. device, which stands for Software and Hardware for Invisible Eavesdroppers and Lurkers Detection.
This amply-named project uses an Arduino Uno to control a pair of WS2812B lights mounted to the top of your computer monitor. Lights shine through acrylic icons of a microphone and camera, with red indicating “on” and green for “off” and safe. There is also a buzzer to note status changes.
The S.H.I.E.L.D. communicates with the host PC over USB, which runs a companion monitoring app that can be used independently as well. More details are available on GitHub, and a demo/explanation can be seen in Levis’ video below.
