This reminded me of an evil prank I did on some friends of mine when in university - CD burners had just become a thing, and at the local concert venue where we volunteered, a handful of burned CDs soon appeared at the mixing console with various music the engineers liked to listen to while getting ready for a gig. Anyway, I ripped the discs, added a nice 50Hz hum under the music and burned new copies which I then le…

I'm pretty sure 50Hz is electricity, not gas.

Back in the nineties, it was a prank.

I attended the 1989 MackHack[0]. I had the Oscar The Grouch trash can hack.

I also wired all our Macs to run the Energizer Bunny hack. That was fun. It would have gotten me fired, a few years later, though.

Metal detector ists ! Ah no, oops, you had it right, force of habit ;)

I'm not sure if the habit is because of the show or not, but I wanted to note for anyone who might be reading that "Detectorists" is a really charming British show that I highly recommend.

Personally, even the remotest possibility of someone broadcasting "evacuate your rooms, there is a fire/active shooter in the building" seems worth spending a few hours protecting against.

....why? No, honestly, why? Would you protect against someone running down the corridor shouting the same thing?

It's a lot more official if it's coming from the elevator speakers. It's also a lot harder to track down who did it.

That's more of an annoyance than a safety issue though. This is definitely one of those YAGNI things where it's not worth worrying about until it becomes a recurring issue, which is highly unlikely.

It'd be far more trivial to put a wireless speaker in an elevator than it would be to reverse engineer this.
