@dt_hayden Your story about dog poo gave me a good chuckle on an otherwise dismal Monday with a holiday weekend seeming very far off. I had a similar, yet entirely different, experience with a bad smell. We were on an airplane and were seated almost directly across from the lavatory. Midway into flight, a miasma filled the air that I could only surmise was emanating from the toilet area. A flight attendant came by, sniffed, and turned on her hell and walked away. She came back, wielding a spray can, presumably with deodoarant and began to spray mightily in the aisles and passenger seats nearby. I suddently noticed that the passenger in front of us bore a mightly resemblnce to "pigpen" and was the obvious source of the stinky smell.
Interesting concept, but a long time ago my Dad showed me how to make a locally-controlled mechanical equivalent (he learned this from an older brother and was passing along the mechanical engineering wisdom). Bend a piece of wire coat hanger into a U-shape, fasten a steel washer with 2 rubber bands to the looped tips of the U, and wind it up. Once armed, plant it under a cheek in a public place, such as a bingo hall. Trigger it by raising a cheek slightly and let the spinning washer unwind loudly. Don't need no stinkin' op-amps for this...
But have to wonder - is this digital or analog? And is it patentable?
@SC Ramjet.....nice idea. I have got him (and a couple of others) with a remote controlled fart box I got for $7 from our "Book Club" - a vendor who every couple of weeks leaves samples of various books and other goodies for sale at our reception. I've already had way more than $7 worth of fun from it :-)
@dt_hayden: This time I decided to suspect something closer to home and sure enough found a good size desposit of dog doo on my shoes.
LOL Good one.
A couple of evenings ago my wife and I were reading / on our iPads / watchingTV (typical multi-tasking). She was on the sofa and I was in my command chair. Every now and then I would notice her look up at me -- so I'd look at her and give her a smile.
Eventually she said: "Do you have gas?" It surned out she hadn't noticed one of our dogs was curled up pressed against the sofa under her feet -- he was being a little "potent" as it were and she was at ground zero -- meanwhile I was "upwind" of both of them because the air vents are in the ceiling a bit behand my chair.
Max, I had a similar episode years ago that involved smells. I was sitting in my cube at work when it suddenly smelled like my coworker in the next cube had a bad case of gas. Finally, I could take it no more and got up to get some fresh air. Walking by the next cube, it was empty, and I thought the occupant must have got up and left. I came back a few minutes later and the air had clearerd. I resumed working and the smell reappeared. Again it became intolerable and I got up for a short walk. Walking by the next cube, it was empty, and I thought Steve must have got up and left again. What are the odds? On returning to my cube, the air had cleared and I resumed working only to have the smell return. This time I decided to suspect something closer to home and sure enough found a good size desposit of dog doo on my shoes.
@David this reminds me of a prank pulled on my by my workmate
Ever had a phone plug appear open because a prankster dipped it into clear varnish and let it dry overnight? Took me a few minutes to figure out why the speaker would not work at our next jam session the next day - the clue was his failure to keep a straight face while watching my confusion.
@ScRamJet: When he stretches his legs under the desk it goes off. Heh Heh Heh.
Although not related, this reminded me of something that happened only yesterday. When I came out of our bedroom on my way to join my wife out on our back deck, I became aware of a strange "scratching" sound.
It was one of those sounds that bounces off the walls so you aren't quite sure where it's coming from. I thought it might be one of our cats, so I went hunting, but I couldn't see anything. When I stopped walking, so did the sound. I looked around but couldn't see anything, so I started to head out ... the two cats were sitting next to the back door.
Hmmm. I went back down the corridor into the laundry room for another look. It took me ages to realize that the sound was coming from some new "vacation / swimming / whatever" shorts that my father-in-law had given me for my recent birthday -- no wonder the sound stopped when I stopped walking.
I felt like a fool (but where was I going to find one at that time of the day? LOL)
@Prabakhar - this reminds me of a prank pulled on my by my workmate (one of an endless series of them.....)
He covered the speaker holes in my telephone headphones with white double sided tape. Then, so I would not notice, he put black insulation tape over that, so on cursory inspection it looked normal. Took me a while to figure it out, especially as the phone was old and we'd had some problem with others of the same type giving low output . It was one of his better pranks.....
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.
