Vigorous exercise keeps the tunes coming

There are cars that increase the radio volume as you drive faster, and video games that ramp up the music as your gameplay improves (we’re looking at you SSX Tricky). Now you can add that feature to your workout with [Polymithic's] Motion Feedback MP3 Player. It uses a passive infrared sensor to detect motion so there’s no need to wear any electronics. But if you used some Bluetooth headphones you could bring the system with you to the gym, just don’t exercise so hard that you blow your eardrums out.

    Lol, this is hilarious.

    First article I’ve seen on HAD with only 2 comments in 24 hours. And over a weekend nonetheless!

    Don’t worry Polymithic, your hack is good. Actually, very good. Your IR sensor measurement is simple and brilliant. It’s just that most of us would be like hirudinea there. How could we even test it to see if it works?

    The title is a little overstated.

    should have been “PIR triggered volume control,
    with volume constantly increasing as you walk around”

    if it is a PIR, it is not really monitoring activity but the presence, any single move, like just moving the head will trigger it.
    It will not give any difference if you jump fast or slow. So i am sure thet you cannot decrease the volume by jumping slower.
