Wasn't Meep the little alien on Phineas and Ferb? Sorry about that. This actually happened to us about six weeks ago. Turns out the fire alarm in my son's bedroom in our recent addition had a faulty hot wire connection to the 110 volt house wiring. So the alarm ran off batteries for about six months and then complained. Since my meter didn't show the 110 volts present, I climbed into the attic to hunt down the problem. Then realized all I had to do was take the unit apart from the hallway to fix the wire. My wife says this is because I always expect the problem to be a worst case scenario. Bummer. But at least it was a low cost problem to fix.
Not 'meep', but speaking of long term retaliatory did you ever hear about the woman who just before she left her husband and his girlfriend stuffed his curtain rods full of raw shrimp? Eeeuuu!
One of my kids once left his cordless phone in the living room under the newspaper basket. Of course when the battery got low it meeped, I hunted for the darn thing for hours and didn't even know what I was looking for. Wonder why they don't make every 10th meep longer duration?
The BBC engineers in london had a gadget that sounded just like their pagers but bleeped only briefly every so many minutes, just enough to stop whichever senior engineer was staying overnight in an office from sleeping but short enough burst to ensure they never found it. Apparently these evil pranks had been going on for some years, indeed they may still be doing so now. It was a fun place to start my career but I'm glad of the quieter life now. :-)
Are you telling us that you are the human incarnation of Dilbert and a reality show is in the works . . .
I agree with the statement, that the frequency of lowVoltage Battry warning could be improved. I have assumed that is intended to provide the longest warning possible to get our attention eventually, like a whining child.
I once worked on a project refitting a shop. The Project manager had a PC with a screen saver that had crickets, owls hooting and various other nocturnal noises. He also had one (only one) CD, of Simply Red, which he had on repeat play.... now, whenever I hear Simply Red songs, I wind up wondering where the cricketa and owls are....
Reminds me of the retaliatory prank played on the late Jim Williams:
"To get back I bought 8 watches that beeped only once every 24 hours, they were expertly installed in his walls, bed, heating ducts and on his dog. He never found all of them.... they beeped for 5 years until the batteries died."
A friend some time ago gave me an electronic "Cricket" which he built from a kit and it didn't work. It beeps occasionally when it is dark, but it has a photocell on it and shuts up if it gets light on it. Object: to annoy the crap out of anyone who is near it. I gotta fix it sometime (after Max's atmosheric monitor and my HP counter and my calibrator and my DMM that doesnt work on ac and...and.....)
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
