So I wanted to drop a pinned comment in here to acknowledge and share some of the really helpful messages I've gotten from folk clarifying Sabbath rules to me. I nearly married someone who was Jewish, so I'm very familiar with the hurdles of keeping a kosher kitchen, etc, but never having been Jewish myself I wasn't familiar with some of this and I have been interested to hear these details. 👍 Here's what I've learned, thanks to folk like Indora and others who have reached out to me: * On the Sabbath the prevailing rule is that you shouldn't make *new* work or have others make new work for you. * With Sabbath Mode on elevators, the elevator is going to do the same thing we see it doing, regardless of whether or not it has any passengers. (Similarly, many observant folk believe that on the Sabbath you can step onto a moving escalator, but you can't make the escalator move if it was stopped.) * Many of the rules regarding power usage (even with modern electronic devices) are derived from the original Sabbath rule about fire: striking a fire is not allowed. (And most modern interpretations treat "turning on a switch" as "striking a fire") * But the Sabbath rules make distinction between striking/kindling a new fire versus maintaining a fire that was already going. So, again, making use of or somehow supporting the operation of an electronic device on the Sabbath may be seen as permissible as long as it was started before the Sabbath began. In conversations with folk, I pointed out that much of what Howard and I said during this section of the talk was regarding things like Beam-Break sensors and whether the presence of a human could be seen as "flipping a switch" in the elevator controller. But I did begin to understand more about not "making new work" etc etc. It was explained to me that things like the elevator's internal adjustments due to the presence of a person are secondary to the main work it was already doing: going from floor to floor. And also (I found this the most interesting, and I like how it is pragmatic and practical) "one can argue that the actions the elevator is taking are OK because they are *safety* actions. Nearly every Sabbath rule can be set aside for these. I know several observant Jews who use continuous glucose monitors and such to manage diabetes on the sabbath. Health and safety trumps everything else." (again, credit there to Indora) I like that and I appreciate all of you who have reached out to help me learn, on this and in comments on other videos, as well! 👍😁👍

IIRC at least in come cases the beams are deactivated (but pressure sensors are not) when "shabbat mode" is activated, and so many of these secondary systems are also not fully active. Regardless there is still much debate whether use of a shabbat elevator is allowed, and by whom. Some ultra-Orthodox Jews do not use them at all, while some people hold that only those who need it (for accessibility reasons) should use one. The pragmatic side - which I liked you found interesting - is often the framework that guides the rules in Judaism. Safety and life above all else - even at the expense of the sabbath, then observance of the rules between you and your fellow person, then observance of the rules between you and God. edit: BTW - the use of a "sabbath goy" isn't as permissible or straightforward as pop culture has lead people to think it is. I can't just ask someone who isn't Jewish to do anything I want for any reason on Shabbat.

Your last point about safety is actually quite interesting and relevant to something my Dad told me. He is Jewish(he converted to Judaism as an adult) and I quite often quiz him about the rules of being Kosher and Shabbat etc. His brand is what's called Progressive Judaism, in contrast to the very strict Orthodox Judaism they take a more pragmatic approach to the rules. He mentioned a time where he went to a social dinner of some sort and the food was about as far from kosher as could be, something along the lines of a dish with ham/bacon and cheese in it. I can't exactly remember his words verbatim but he said something similar to "Sometimes it's better to be nice than right." That yes eating that food was not kosher, however eating that food was being a good neighbor and appreciating the efforts of a friend's hard work in the kitchen, in essence being a good guest, which I believe is touched upon in the Torah. I believe a lot of the interpretation of 'breaking the rules' has to do with intent, of course that judgement changes by the individual. On the other hand however he did tell me a story of when he visited an Orthodox Synagogue where one Friday evening the automatic lights had forgot to be set there was a crisis cause nobody could turn them on until my Dad offered to and one of the worshippers literally used my Dad's hand to turn all the switches on as if it 'wasn't him' who turned the switches on. That attitude is incredibly off putting and incredibly hypocritical since of course that worshipper drove to and from the Synagogue in his car. The difference I believe is the attitude behind it and the pragmatism. Of course it doesn't matter to me, I spend most of my friday nights happily eating ham and cheese toasties whilst using most of my electronic devices!

@@artyboy92 I would say that Orthodox Jews would probably politely avoid the not kosher food. There are ways of being a good neighbor without having to eat not kosher. If this was a life of death situation (let's say, he was stranded on a desert isle) then eating not kosher would probably be ok. When one needs to break the rules a lot of the emphasis is about the "why" and "how" - if it can be done in a way that is different than normal, better that way. If it's to save lives, that's permitted. In regards to your second story, I am very confused. If this was an Orthodox synagogue, they wouldn't be ok with your dad flipping a switch - since he is Jewish too, and definitely wouldn't use his arm to flip a switch. They also wouldn't have driven to synagogue, and if they did they would likely be ok with flipping a switch themselves. Either that person was trying to hide their "lesser" level of observance from the rest of the community, or something is missing from the story.

I was once walking thru downtown Portland Oregon with my honey, when I saw across the street a very old brick building that had a cornice of granite around the top that said “Otis Elevator Company” and I stopped to stare at it and started laughing softly. “What’s so funny? “ asked my girl. “That used to be the Otis elevator company building”. And she looked and said, “ yeah, but why is that funny? “. And I replied, “Its only one story tall.”

When I was a carpenter, working in a refinery, I got trapped inside an old Ottis elevator for five hours with a guy who was claustrophobic. Bad thing was, this elevator was on a running processing unit and the whole superstructure shook. So here we are, not able to get out, stuck between the 8th and 9th floor (industrial floors, 25’-30’), being slammed from wall to wall like being in a washing machine, not knowing if the “emergency call” button was connected to anything and it’s too loud to yell for help. Come to find out, the “emergency call” button wasn’t connected to anything and/or the light had burned out. No one knew we were in there until the elevator repair team showed up. The guy that was in there with me never rode that elevator again. He would always take the stairs…..

As a twelve-year-old kid in the 1960's, I would spend hours playing in the elevator machine room at the hotel where we lived. It was fascinating to watch the equipment operating, and I eventually figured out how to manipulate the relays on the control board to make it do whatever I wanted. For example, when a passenger entered the elevator and selected floor 6, I could cancel the call and send them to floor 7. Other times, I'd send the elevator to the floor they selected but keep the door from opening, and then immediately return the car to the floor they started from. Things like that. Such fun!

I come from the land of expedition level cave exploration. Bad air is almost never a problem in the limestone caves of Kentucky: the air is good and flowing. But I know of accidents in caving where rebreathers were used, leftover from WWII. If you run out of O2 you don't notice because there's no CO2, which is what tells your body you need to take another breath. So you die not knowing anything's wrong. Another danger is open air cave pits (open to the sky) in southern Indiana. Dead leaves both plug the airflow, and generate CO2. Tragically, one person will rappel in and asphyxiate, and worse, not knowing the danger, their buddies die by rappelling down to save them.

Eventually we got hold of the fire dept (cell phone) and they did exactly what you said not to above. That is we climbed out with the elevator not level with the floor.

Thanks yt algorithm, loved this video! Some years ago as a teenager I'd roll around with an auctioneer during summer when I was out of school. There was an auction in one of the old downtown buildings that had these ancient elevators that had the pull down doors. A bunch of us piled in one and hit the up button.....well it didn't go up, it went down and felt like it was a free fall.. it stopped halfway where the building floor level was chest high so we had to crawl out. Apparently the motor started the wrong way due to being overloaded and it went fast enough the emergency brakes activated. The floor we crawled out on was a haunted house so lots of blood and gore , it was great !

Waiting for the fire department makes me laugh. Myself and another rescue paramedic that happened to work in the emergency department with me, and who both have elevator rescue as certifications, nearly got fired, because we got asked to deal with a critical patient stuck in the main elevators. Turns out the elevators were functioning properly, the wheels on the patient beds were just narrow enough to fit between the car and the threshold if perfectly aligned. My coworker and I assessed the situation and lifted the bed up about 1cm with the sick patient on it and we gave each wheel a quick kick while we lifted. This critical patient and 6 staff had been stuck in an elevator at floor level with the doors open for 30 minutes before someone stepped out walked 70m to the ER to ask for help.

I used to be employed as the operator of a geriatric industrial elevator in an old factory in Quebec. I always thought of my job as being on-par with someone who manually operates canal locks or switches railroad tracks from an old control tower by pulling on levers.

Many years ago I managed hotels and at one of them we had an elevator with a window in it and at each landing there was a window. I had the idea to sell advertising space between the floors to local businesses. One of my favorite jobs was to change out the advertising posters during the annual inspection. We had a really cool elevator tech that would let me go with in on the car top in order to change the posters… so much fun.

I used to be a construction supervisor for a company that owned high-rise buildings in Montreal, and they had that old relay kind of elevator controller in one of their buildings. Being in that room while the elevator was functioning and listening to all the clicks and watching the machinery work was fascinating to say the very least.

I have a friend who does social engineering training for...unmentionable agencies. He had a student who had been an elevator inspector before. Lots of cool stories of sneaking around using the elevators.

I used to do maintenance for a wireless ISP in a fairly large city. Can't tell you how many high-rise buildings had our antennas on the outside of the machine rooms and the racks inside because they were the best spot on the roof for that stuff. So of course I had the keys.

1) Secret life of Machines was an awesome TV show (Clip of british guy on elevator) and I remember that episode 2) I had a rapid descent event on an elevator, no idea how long it took to go from 17th floor to 5. Then it turned into an incredibly slow descent - it took 10 minutes to go 5 floors to the bottom before it let me off.

The hospital in the town where I grew up was built on a sloped site and expanded over the years. As a result, two different parts of the hospital share an elevator that has half-floor buttons and front and back doors.

Being from the elevator field most of this information is very accurate. One thing you could do different then buying the key boxes and cutting the keys is get an elevator license then order the keys from a distributor lol

Elevator license is usually not always enough. For example here in sweden, if you want to order access credentials to building sites, you BOTH need a license (credential that you have gone through the certification course) AND you also need a permission paper from your employer with his signature (to show that you are acting for a company, not acting "privately"). And usually these credentials have to be paid by the company too, you can't pay them yourself. This to prevent people from "black-ordering" these in some company's name - by having it so the accounting will notice the bill if the credentials wasn't legitimately ordered by the company.

The keyboxes weren't for elevator keys, these guys already are licensed, those boxes are FIRE keyboxes, you must be a first responder to get those, and even then, those are supposed to be daily check-in check-out logged in with the fire truck and supervisor you're assigned to, don't just get to keep the keys or take home.

there is a type of elevator once present in europe called a paternoster lift, almost all of them are gone but i was lucky enough to ride one a few years back. it is a continuously moving circulating loop like a giant chain. each floor has two openings, one for up, the other for down. the cars you ride are open, you can see each floor as you pass through and just step off at your desired level. really fascinating and well worth a look.

I spent many years outfitting government buildings and top security facilities. One of the stranger ones was a four story building that had an elevator panel that went: 1,2,3,4, then a big gap then a 7 down in the bottom corner of the panel near the floor and a key next to it. The one time i saw 7 used it was by a guy in full biohazard suit with a cylinder on a trolley. I came around the corner and went to walk in the elevator and he just looked up at us from the ground with his key turned and finger hovering over 7. "I'll get the next one mate no worries." Why does a four story building have 1234 and 7? wheres 5 and 6!! This particular building has a one kilometre long probe driven into the earth underneath it for seismic reading. Geoscience Canberra

i caught that tim hunkin bit! practical demonstrations are a lost art and the funny bit, i watched the commentary back and forth between dev and tim when it actually happened! :D

I was trapped in an elevator in a new building after an earthquake in the mid 80s. When I pressed the autodial emergency button, I got "You must first dial a 1 before dialing this number. Please try again." On a weekend. In an empty building. The sprinkler system had gone off due to the shaking (not due to a fire) and water was running down the shaft from the upper floors. They had contaminated the sensors so the hydraulic ram wasn't moving, it was just "jumping" a few inches every 20 seconds. I was hoping it would just settle to the ground floor. It didn't. I was able to get the doors open as it was almost at the bottom floor and crawled out.

The first one I rode on the top didn't have the ropes fixed to the car - they went round pulleys and back up the shaft. So yeah, when the lift moved you had a pair of pulleys you could trap your fingers in !

This video just randomly popped up in my feed. I just wanted to comment, thank you for posting this talk; lots of super interesting details and depth. Incredibly interesting and captivating! What interested me the most was the safety systems that were described to keep the carts and passengers safe. Truly amazing, thank you

"The elevator wants the occupants to survive, because who wants squished humans cluttering up one's car interior?"

Dev, you’re literally the only guy i’d ever actually trust to convince me a 1.5 hour video about crazy obscure elevator tech/security stuff is going to somehow hold my attention and that i’m gonna watch the entire thing without realizing it. you’re awesome. question though: i’ve often wondered this, but how would an interested individual go about getting a foot in the door of the pen testing industry and related industries?

Another elevator talk? Score!

This video popped up in my feed a few months ago, and I skipped through a bit, expecting a video essay, just to see a bunch of PPT sides and went, "Well this'll be boring," then clicked off. Now, here I am, after actually watching the whole video. I fell asleep (granted, watching this in bed) during the part with the leaky hydro valve body, but was able to seek right back to that part because I was paying so much attention to the video I had previously dismissed. Great video 👏

I was once trapped in a lift by myself. None of the internal buttons did anything, including the alarm and intercom buttons. I got out by yelling and banging on the door until someone pressed the call button outside. It was a Schindler Lift BTW. I've been wary of lifts ever since.

Last time I nearly got stuck in an elevator was because of an issue with the 3-phase supply, caused the motor to burn out and filled all floors of the office building with smoke.

Forget the elevator talk! He's almost disposed of that body!

As someone having been trapped in an elevator between floors with a non-working telephone i really appreciate this video.

One of those great talks where they ask for a few more minutes and everyone wants the next hour

Being obliquely connected to the construction industry I recently found that the deadliest trade on a construction site is the elevator installer/tech. due to falls. It’s also one of the most lucrative; hundreds per hour, 2 man crew minimum, and 4 hour minimum time per call out. The elevator industry is also the hardest to get into for the average guy; it seems to be all ‘sown up’ by male family members; brothers, uncles, fathers and sons.

That half-floor panel I've seen very similar before. There was a facility I worked in where each floor was 30-40 feet or so high because they did design and testing on very large equipment. The half floors were the catwalk level. So 3 was the main floor of the third floor, and 3½ was the catwalk level of the 3rd floor, and so on.

I remember me and a friend were in an elevator that got stuck. We popped open the phone panel and called the number it said in case of emergency. I called on my cell. The phone in the evelvator started ringing, me and my friend both looked at it and slowly looked at each other with that look of 'are you f*ckin serious'. We were in that elevator for 5 hours even AFTER calling fire and rescue.

Another good video Ollam. Elevators are fascinating. Been in/around a couple of the hoist rooms while working for a card access/camera company. The super old relays for elevators are loud af. Also big beefy boys. Up at the very top of sky scrapers are a really amazing place too. Lots of things going on behind the scenes.

I love this talk every time I see some iteration of it.

I recently returned to my workplace after being remote for over a year, and while I was gone all the elevators had Code Blue switches installed on the basement hall panels. Not a hospital or medical facility of any kind, so it's curious why they added it and why only on one floor. The fire service switch is still on the ground floor.

Maybe if it's a basement, maybe there was a risk (either a real risk or one believed to exist by the building management or local regulations) of someone getting an injury from exhaust fumes of cars or trucks at parking spaces or loading docks, or electrocuted in a substation room, or something like that?

From the security point of view, no lock is ever safe but elevators could do one thing you don't ever mention here and that is to report potential security breaches. Meaning if security is a focus, there's going to be someone on guard and if someone turns the elevator to firefighter mode, it could sound an alarm on that person's desk leaving it up to them to decide if someone should go check it or if it's fine because the building is on fire. If that's not already being done, I'm surprised.

In his other talks about elevators this is actually mentioned as a function of most elevator controllers. They often have extra dry contacts which you can wire into your monitoring system to indicate if it's gone into independent or fire mode. Modern ones I'd presume can do this all over network with the right integration.

I did see this talk, or one very similar in another venue, a while back, and it was still cool to watch it again. When I saw it the first time, the biggest "WTF?!?" moment (among many) was seeing the Windows XP logo. Thanks for sharing again, Olaf!

I was in a lift in the uk, as i got in it moved alot, i bounced and it dropped a whole level that needed a key to get to. Was interesting!

I have a question: Do you think there will be some new exploits with the new-ish Sharry lift / office access software? Or will you just go straight to the hardware behind it as usual, since that will probably remain mostly the same?

18:42 about cancelling, I worked in a building once where doubleclicking in the cab would indeed cancel the floor. Not to get somewhere faster, but just as a prank, some of the people, especially those in suit-n-tie, would stand with their back to the buttons and sneakily randomly cancel a floor behind their back XD

Ex bldg mgmt who dealt with more than my fair share of elevator issues, mishaps and hacks. I really enjoyed this video!

I don't know if it's still being used but back in the 70s my grandfather was a elevator operator in the original Singer sewing machine factory in Elizabeth NJ , I remember him showing me how he started it up each morning they had a huge generator inside a cage the thing was the size of a small box truck, the elevator was 100% manual with a metal handle and a wood grip the doors were also manual on counter weights he used to let me level it at stops when the call bell rang.

I really enjoy your OG talks and the elevator one is a really solid one. Having a bit of a variation will be great. I doubt I will manage to watch all of it today as I have to get up early tomorrow

Always love watching elevator hacking videos. I serviced and bulid elevators for 4 years.

@deviantOllam I used to work at Schindler. In the 80s I was on the software development team working on the first microcontroller-controlled lift system (Miconic VX). I was responsible for the proprietary communication system between the floor, cabin, and control room (the lift bus), the group bus (between lifts working in a group), and the building bus (from all groups to the main security desk or emergency outside control centre). I inserted an Easter Egg into the code that would intercept a particular sequence of floor calls made within two seconds inside the cabin that would inject a call reset (all floor service requests would be cancelled) and put the cabin into independent mode. The next floor to be selected (mine) would then be in express mode with security override. After I had exited the cabin, normal service resumed for the other bewildered travellers (who would need to select their floors again)! This would only work on installations with more than 4 or more floors. The software was actually part of the communication protocol and not in the controller logic!

Though I've seen the Elevator Hacking talk before, this is still a good video to watch.

I've also confused one lift. Going up, I opened the car doors. Got them closed again and the lift started going down - but the floor indication carried on counting upwards! Got down to about the third floor before indicating the correct floor again !

On the campus where I work one building has an elevator that looks ancient and is at least mostly human controlled I've been in it and had to control it to line up with the floors and almost hit the top trying to see how far it went and there is even graffiti in the shaft. Also i remember years ago having a coworker get stuck while vacuuming an elevator the cord jammed in the door and i eventually figured out how to push a rod in the hole on the outer door to open them up.

Anecdote time: One time, I noticed an elevator that would play a bell sound file after levelling and opening the doors at a floor. If you were already at the floor, the sound would still play. I spammed the button for the floor I was on. This crashed the control computer. All indicators turned off, all calls were dropped. The elevator then proceeded to slowly lower itself to the lower limit switch. Then it played a startup sound, levelled at the lowest floor, and let us out. Unfortunately this bug was later patched out.

I work at a transit agency near DO's hometown. We have something like 38 elevators in the system with another 10 coming online this week. I have had the pleasure of being able to chat with the KONE, TK, and Schindler techs when they are out on the frequent repair calls. There is a lot you can learn from them by just being friendly and asking the occasional question. I have gotten to ride on the roof once or twice on a service call. I would say the number one thing to do with a public elevator if you find yourself trapped is to push the doors closed. The drug users will crack a door open between floors to force the car to stop while they sleep off their hit. This ends up causing the doors to not register as closed all of the time.

If you were to break the safety circuit while the elevator is moving, what are the chances of it moving once you close the circuit again, rather than requiring a reset in the machine room? Is there an easy way to tell, such as it being consistent across an entire brand?

@GlennBrockett

2 жыл бұрын

​@@user2C47 For the doors, generally if the door is partly open (Logically "Not closed") it will stop until the circuit is closed again. Usually this is due to the wear on the doors by the crackheads. When the circuit is closed by pushing the doors back closed, the elevator will resume operations. Unless the switches themselves are broken, this will fix it.
