I drive a modified car, this is obviously the glass break sensors in the house. My car sets the sensors of other aftermarket car alarms off as I drive around because of the exhaust frequency. I imagine the same thing is happening here.

#172This reminds me of a “bug” I found when working for a company that sells package lockers to apartment buildings. We used iPads for the user interface and had monitoring in place to alert us if an iPad went offline. At only one location with two iPads one would go offline almost every day (but not every day) between 12pm and 1pm, for 10-20 minutes. Never the same time of day, and never the same length of time. It was…
Ha!
Many years ago I had an optical mouse that would act erratically in the afternoons (just wouldn't register movement). It seemed to be ok if I squeezed it while I was using it so I figured it was a connection somewhere. Eventually I realised that it was the afternoon sun streaming in through the plastic seam and somehow stopping the sensor.

#174Reminds me of this story where a car was 'allergic' to vanilla ice cream: https://news.ycombinator.com/item?id=13347852

I lived in an apartment in Fl and during the month of August and into September, every afternoon my cable would cut out for several hours. Happened every year for the three years I was there and only during that part of the year. Could never get Comcast to get a tech out there during the correct time frame, but they had a box mounted on one wall and that time of year it got direct sunlight and I suspect heat was to b…
I worked for a cable ISP helpdesk once and during a particularly hot summer I vividly remember an on/off outage where we'd be getting regular updates from the field guys along the lines of: "We opened the doors and it works now." and "It failed again but we got a fan from the neighbors and that seems to help!"

#176When 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 tag…

Merry xmas!

#177Reminds me of "story of a car that wouldn’t start every time its owner bought vanilla ice cream". http://www.kepner-tregoe.com/blog/help-my-car-is-allergic-to...
That story is so incredibly far-fetched, and further comprised by the not-so-subtle product plugs liberally sprinkled at every turn.

#178Is 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…
Actually imo it makes most sense to call the alarm company and have them troubleshoot it while you're there with the car.
That way they can see debug output of what happens when he hits reverse.

#179Earlier quoted context omitted.
I can often tell that I'm about to receive a text message because my poorly shielded computer speakers will start buzzing. I assume it's caused by a transmission from my phone's radio inducing a current in the amplification circuit. I would guess this is what's happening with your GFI. Even though you're receiving the call, your phone is probably transmitting too (sending back the equivalent of an ACK or something).…
I’m guessing car manufacturers have caught onto this. I drove a year 2000 car whose speakers would know I was about to receive a text/call several seconds before receiving it. I don’t think I’ve been in a model later than 2008 that’s had this problem. The noise, like the AOL dialup modem beeps, are one of those things that become cemented in your brain and immediately recall themselves as soon as you think about them…

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.
My smoke detectors made a boast on the packaging they featured a fool-proof low battery indication, without going into any details. I bought half a dozen of them to install in our new house years ago, thinking the nightly find-the-beeping- ^+=¥€ games were finally a thing of the past. When one started beeping, I did the rounds, figuring I'd be back in bed in minutes. Well, I wasn't. Turned out the fool-proof indicati…
Unfortunately as some who isn't colour blind and doesn't have any close friends who are, it's easy to forget about these concerns. I think attention to accessibility issues like this is one of the things that separates great designers from good ones.
