@hamjudo cool stuff. My college and university experience was not in engineering although I would have likely enjoyed it but for the “maths” part.
One of my favorite discretionary courses was “The Physics of Sound”. In it we made our own piezoelectric tweeters. And demonstrated noise cancellation by setting up a low frequency standing wave from one end of the hall… then did the same from the opposite end of the hall. Then traded off standing in the middle of the hall while we adjusted the opposite end-generated waves into and perfectly out of phase using an oscilloscope. Of course the sound got louder and then went silent. Will never forget those learnings.
Yeah, I definitely need one of these to fit in these days.
Certainly can’t imagine how I could enjoy hiking without the soothing sound of trashy technobeat blaring from one of these hanging off some random bro’s backpack.
<get off my lawn> I’m enjoying a hike out in nature, away from the city, hearing birds, finding wildflowers, breathing fresh air. And then I come across some people blasting shitty music from their Bluetooth speaker dangling from their pack. On repeat with more and more people doing this. And now this terribly rude behavior is being encouraged with marketing pics. Ugh. </get off my lawn rant>
I probably didn’t fully understand what this package was, but I’m not too upset. There are two individual (and not aimed to be used as a pair) bluetooth speakers each the size of an ice-cream sandwich and with a stretchy loop connected. I’m not sure what they’re really for, but maybe I will find a use! They are easy to pair with a bluetooth phone or any source. They sound pretty good, certainly acceptable for spoken word.
