Should I use that Elevator?

I’m returning from the Embedded World in Nรผrnberg/Germany. A very busy schedule, a crowed exhibition, and a *lot* of good stuff. IoT (Internet of Things) was everywhere, to the point that I heard from visitors that they do not want to hear it anymore, about it because it so over-used ;-). And it seems that every vendor wants to have its feet in it, without really knowing where it could go. Sounds like in the early days of the ‘internet’, and everyone fears that if he has not ‘IoT’ somewhere, they might miss something.

But the topic here is something completely different: I was staying at a small and inexpensive hotel near the city center. I returned last night around 11pm. I was really tired from the long day, and with a heavy notebook back with me. I was going to enter the elevator to the upper floors, when I saw this signage on the elevator door (sorry the bad image quality):

So there I was staying in front of that door, about to press the button, still thinking about the consequences. Not a good sign. Can I take the risk? What would you do?

Happy Elevating ๐Ÿ™‚

    • Hmm, indeed. I was not thinking about that. But that would mean that the hamsters have pretty regular work time. That would indeed make sense. I would not be worried about not having full power, more about no power for a long time?

  1. Some years ago at an amusement park in Virginia we rode on a monorail cable car ride. I was more interested in the mechanism than the ride. It was powered by a VW Kรคfermotor. Somehow hamsters in a cage reminded me of that.

    A friend of mine at the office got stuck in an elevator once. Thunderstorm at the wrong moment, lightning strike “rebooted” the controller. He was between floors and I was able to release the latch on the outside door somehow and pry it open and he climbed out. If I wasn’t there late who knows how long he’d have been in there.

    BTW… Internet of Things — Pfft! ๐Ÿ™‚

  2. The short answer is “no”, I wouldn’t use that elevator !
    I know from a very good source that the “INVITE Hotel” doesn’t use Freescale Microcontrollers drivers in their elevators! ๐Ÿ™‚

  3. It sounds to me like it is a noisy elevator, and that one of the hotel residents was threatening to hurt anyone who disturbed his sleep.

    I always prefer to know where the stairs are and use them if possible anyway. You can’t use the elevator if there is a fire.

  4. Probably I would not notice such a sign ๐Ÿ™‚ No problem with my eyes but my brain does not have multitasking capability, and when I am busy thinking something, do not realize many other things.

    Also, -quite often- I have trouble with the elevators, especially with buttons. For example, if I am to go up from the ground floor, I press the zero button! The elevator does not start of course. At that point, many explanations come into my mind; such as, “there may be a problem in the connection between the button and the MCU”, or “maybe the MCU got stuck in an interrupt service routine and cannot process the action”, and so on; but not the simple fact that “I am pushing the wrong button!”

    So, when I am pressing it over and over, sometimes somebody else gets in the elevator and “rescues” me from this deadlock, or sometimes I succeed without help. My wife (a non-technical person) never does such a mistake; but I guess I am not alone, most of the MCU guys occasionally do such things, right?

    • Absolutely! You are not alone, and it happens to me too ๐Ÿ™‚ I have always problems with the numbering of the ground floor. As a computer science engineer, I like to start with the number zero, so at least some elevators have ‘0’ as the ground floor. Some use ‘E’ (entry level’?) or ‘G’ Ground Level. And then there is sometimes ‘M’ is is the floor just above the entry level. Geeee! My wife is always confused why “the first floor is not one, but zero”. I think we as engineering community finally should take an effort to consolidate all this different labeling, right? ๐Ÿ˜‰

      • Happy to hear that ๐Ÿ™‚ I start counting from zero too, and stop at FF, or return back to zero!

        Btw, did you take the elevator that night? Risk/reward ratio does not seem encouraging indeed, unless your room was at 4th or upper…

        • Let me hold off a little with disclosing what my decision was ;-). I can tell that I was carefully considering if a) I would be alone in that elevator or b) who else would be with me there ๐Ÿ™‚

  5. My guess is that the warning was for personal safety, rather than technological reliability. It is safe to assume that if the elevator is technologically safe to use at 10:29 it would be equally safe at 10:30. (This is assuming the electrical service was also just as reliable after 10:30.)

    If there is no hotel security available after 10:30, it might be unwise for some people to confine themselves in such a place at such a time.

    It is unfortunate that such is the case in so many places nowadays.

    What did you do?

    • Good assessment! After doing some research, it was clear that a) after 22:30 there is nobody there from the staff and b) it happened in the past that the elevator got stuck during night time. So I was there, reading and wondering about that sign. And a nice and cute girl wanted to take the elevator too, and was wondering as well about that sign. We looked at each other, discussed the pros and possible cons of taking the elevator. I had some food, she had some beverages, both had mobile phones, so we nodded at each other that we would be able to survive a night in the worst case if the elevator got stuck. We took it, and it worked without a problem. In any case, we would have been warned ;-).

  6. During my last year of university, my school put up signs that said “Save electricity and get some exercise; take the stairs!”. Maybe if they added this sign, it’d be the extra push needed for me to take their advice =)
