Ever notice how much louder commercials are than the actual program you're watching? Every time a break hits, it's like they're yelling at you about buying their product. Instructables user techbitar shows us how to fix the problem with a little DIY project.
Basically, you place this little device next to your TV and it monitors the volume. When it detects your TV going over a preset threshold, it will send the "volume down" signal to your TV. You'll need an Arduino and some small miscellaneous electronics parts to make it happen, and if you're familiar with building on the Arduino (which we've talked about before), it shouldn't be too difficult. Check out the video above to see the loudness guard in action, or hit the link below for the full step-by-step instructions.
