Working with headphones on usually means you’d rather not be bothered, but sometimes it means you’re just listening to something while you work. If you want to be available despite your cans being on, why not build your own alert button?

Enter developer Nick Sypteras, who wanted to solve the problem of coworkers requesting his attention while his headphones were on. Working in a cubicle, he wrote, “There’s no way for a visitor to my desk to get my attention other than by waving their hand in my face, making loud noises behind me, etc.” So he broke out the soldering iron, a Staples Easy Button, and an Adafruit microcontroller.

Your favorite technology company, Google, is working on an upcoming feature that could put the kibosh on autoplaying videos for good. Soon you’ll be able to silence the worst offenders permanently, saving you the headache of searching for a mute button over and over again.

Enabling this feature will not only enable the speaker indicator in your tab, but will allow you to right-click and mute said tab, or multiple tabs depending on your selection. It won’t keep that site muted if you decide to close and reopen the tab, but it’ll scratch the itch until this experimental feature gets into the hands of normal Chrome users.
