My house has 6 fire alarms, when they beep there is NO way to tell which one it is making the noise 2/2 the combination of short beep and irregular beeping interval. My solution is to just change all the batteries at once so i dont have to guess (and if you guess wrong you then you wont sleep tomorrow because of the beeping) I wish there was some visual indicator to tell which one was faulty.

I believe they all beep because they want you to replace all the batteries. I had this happen a few months ago except it wasn't a low battery alarm. It kept yelling "FIRE FIRE" but then turning off. Of course FirstAlert apparently doesn't indicate which alarm is causing it. They say the initiating one flashes a different pattern but I didn't find one. Ended up, after getting no sleep at all, replacing all 9 of them w…

This who thread had me feeling twitchy. How did any of these product designs make it to market?

Time for my story. I was a noobie computer programmer in my first job. After being there for a few months my mouse started to have issues. It stuttered and refused to move correctly. So I'd take the little grey ball out and clean it and it'd be OK again. But the next day it'd do it again. So I ended up with the cleanest fucking mouse on planet earth. Yet every so often it'd stop working... on parts of the screen. Oth…

I recall a story on reddit's talesfromtechsupport a printer would stop working at a certain time of day. I think it was near a skylight or something weird. I have no idea what it was about but your story jogged my memory but not enough to remember it all.

Is it just me who'd love something like this to happen to me? Would be great fun tracking down the source of the problem (if it was my car; probably less so if I was in the house...) There's a lot of options to try to isolate the problem, just thinking out loud here - a) Back into the driveway returning from work. See if alarm goes off. Next morning, see if alarm goes off as you drive out. b) Remove fuse for reverse…

Wait, you had a buzzin when the video card is active as well? Was yours dependent on the refresh rate on the video card? (I haven't found any other mention of a similar problem elsewhere, and mine has been doing that for a few years now.)

When we were kids (dating myself here), my friend had a TV with a remote control back when almost nobody had a TV with a remote. You would push the channel-change button on it and the channel knob (!!!) on the TV would mechanically turn and the channel would change. Well, apparently, the remote used an almost-audible high frequency to signal a channel change and when his dog ran through the living room, the dog's tags would jingle and change the channel on the TV.

The comment from im_from_detroit [1] seems on-point, possibly ultrasonic sound from a backup sensor on the car being received by an ultrasonic detector in the house. [1] https://www.reddit.com/r/cars/comments/7k12fs/neighbors_hous...

Op mentions later there are no sensors. So either a light/shadow thing or a sound/vibration thing.

There are no explicit "parking" sensors (it's not going to beep if you're about to back into something) but all but the base model have blind spot and reverse cross-traffic sensors. I can't find any explicit mention of the trim from OP. It's quite possible he's incorrect in saying he has no sensors.

I have a 2016 WRX with what should be the same exhaust. When you start the car, it starts with a high 2000-2200RPM idle and drops from there. If it needs to warm up, it will sit around ~1800rpm which is exactly where the stock exhaust makes the loudest drone.

So simply starting the car and letting it idle should result in it hitting all the revs that trying to reverse would (unless OP is awful at driving stick and way overrevving it here).

I find it way more likely there's a sensor interference issue than it's an exhaust issue based on the other information. My second guess would be some IR from the halogen running lights / fog lights / other lights in the car interfering with a motion sensor.

But then I was given a super annoying one. In my apartment I heard this beep about once every 90 seconds or so. I tried ignoring it for a while hoping it'd go away.

Off topic to the discussion, but you hit on something that struck a nerve with me so I'm going to go with it . . . Oh good God, this happens to me every time one of my smoke alarm batteries starts to go. I have 6 smoke detectors and an older home where they're not all wired/battery back-up but rather all battery powered. The "chirp at 90 second interval" thing is the worst design in the universe and it bites me every…

Vaguely related - I once met a parrot that had learned to imitate that exact chirp. Maddening.

Along the same lines, I had a hell of a time tracking down the reason my washroom GFI (ground fault interrupter) tripped on random occasions; i.e., the electric outlet would lose power and need to be reset. It turned out that an iPhone receiving a phone call tripped it -- even before it starts to ring! Making a phone call didn't do anything. Here's a 13-second video: https://vimeo.com/247730625 I'd love to hear comme…

The timing sounds like RF interference. I worked in TV a while back, and we were not allowed to have any cell phones (even silenced) on set - they would introduce this crackling sound into lightly-shielded cables near them. The interference would kick in about a second or two before the ringing started, because there's probably some handshake/setup before the receiving phone decides it's actually an incoming call.

In that case too, sending calls didn't trigger the interference, and neither did picking up the received call.

If the remote used an almost-audible sound frequency, the dog probably heard it, too... which would basically mean the remote had a failsafe...

We had one of these as well -- a fairly standard routine of TV after dinner before going to bed quickly taught the dog that the ultrasonic sound made by the "Off" command to the TV meant "everybody go upstairs and go to bed".

You could actually just press that "off" button at any time, and the dog would look around and do that funny "Dog shrug" thing they do, and go upstairs and lie down, even if it was the middle of the day. We had, essentially, a remote controlled dog.
