If you’re anything like me, you find yourself changing the volume on your computer quite often. Some videos are louder than others, sometimes you want the volume muted on your computer while you listen to podcasts or music, and you might need to quickly turn the volume down if you receive a phone call. If you don’t have media controls built into your computer, then you can turn a vintage rotary phone dial into a volume control for your Windows PC.
This volume control device plugs into your computer through USB, and will automatically set every open program’s volume to whatever number you dial. If you dial a “2,” the volume will be set to 20%. Dial an “8” and it will be set to 80%. Dialing “0” sets it to 0% and acts like mute. It’s quick, satisfying, and more fun than clicking around on the volume control in your taskbar.
