    Disagree. DC current will seek the path of least resistance, and will not go down the pole.

    I’m unsure if this is an apartment, but I would start by reaching out to the landlord and say your lights have been acting up whenever they are using it. Maybe say your electric bill has been higher, maybe stage that a little bit by simply leaving a light on for a month. Have them inspect the floor damage too.

    Once they leave, I would install cannibalize a power cable, plug it into the wall and hook the hot wire up to one of the screws.

    The benefit of using AC, is that it is less likely to take the path of least resistance and travels as waves back and forth, doesn’t necessarily matter if they are grounded or not, they will feel it, likely marginally lower since it is also going into everything their 8ft pole is touching.

    …I don’t know why I’m on a villain arc this morning.

      Small correction- AC power doesn’t “travel in waves”. It just oscillates up and down with respect to its reference, and same with its current with respect to its impedance. Just looks like a wave if you look at its position over time.

      With a completed circuit with low impedance, it would trip your breaker. With completed circuit with large enough impedance to not trip breaker, it might burn your apartment down in a number of ways. Could also kill neighbor if they are somehow making a return path, as current disrupts your nervous system where once they get caught in the shock they lose control of their muscles and are held in the current unable to let go, electrocuting them until death. If insulation is high enough to effectively be an open circuit, your neighbor on the pole wouldn’t know it was electrified in the same way a bird sitting up on a power line doesn’t have a clue its anything but a normal wire in the air. Largely depends on how the pole is installed and if its touching any metal or electrical wires where it is mounted on top, bottom, or both. Also if neighbor is ground level or if another apartment beneath them. A lot of variables create.a lot of possible outcomes.

      Would not recommend, lot of risks with little to no chance of any reward

      I’ll be assuming the pole is not grounded (electrically isolated from Earth, the earth pin of sockets, radiators, plumbing etc.)

      The difference is not DC vs AC but between it being connected across two screws, for which a high current source (hundreds of amps at negligible voltage) will heat the metal up - as opposed to connecting a voltage (like 120V mains for AC or 170V single-diode-rectified & smoothed mains for DC) referenced to ground to the pole. The former will draw a lot of current from the source through the screws and metal between them, heating it up. A car battery could briefly deliver hundreds of amps and several kW, making them glow red hot. The latter will create a potential between the pole and ground, which will only draw current when a load is connected between the pole and the ground. For AC, a person’s body’s capacitance to ground, even with insulating shoes, is enough to feel a tingle. For AC or DC of sufficient voltage (above 60 V), they will get a shock if they touch ground and the pole, completing the circuit.

      1. You wont feel 12v at like 60v you maybe start to feel something depending on how you are connected…
      2. You get shocked because the neutral and litteral earth are connected. Not because of reflecting waves…

        1. Do yourself a favor, don’t ever touch a car battery. It will hurt and you will feel it. They show that in movies as torture for a reason. It’s not the voltage in this case, it’s the current. Those batteries are capable of 550 CCA (cold cranking amps). Warm that battery is 685 CA. In fact I think I would consider the car battery more dangerous.

        2. In alternating current the electrons move back and forth across the material similar to a wave striking the shore of a tropical beach… No one said anything about reflecting. Have you never been shocked by an outlet? Shoot, I grew up in a trailer with a short on the front door. If you touched the metal, it wouldn’t even hurt, but you’d certainly know.

          I am an electrical engineer i have touched plenty of 12v and 24v… If movies are you source for eletrical safety then yoi are a idiot…

          Current has nothing to do with that because it doesnt matter that your car battery can supply 100 100000 or 10000GA 12V will not be enough to make a significant current flow through you because your skin and body resistence is way to high… basic like 6 grade physics with current=voltage/resistance (yea i know body is not purly resitive etc but its good enough) whoever said voltage doesnt kill but current does was a idiot… neither does its a combination of a bunch of factors that matter…current voltage time frequency etc…

          I dont even need to write something for point 2 because you have shown to not know basic understanding about dc circuit analysis…wtf

            Hahaha. Ok, I thought you were a young child because you spelled battery differently and your take on everything I said the first time seemed childish. I told you not to touch a car battery because I thought you were a child. I still wouldn’t personally touch it, but that’s not what’s funny. You are NOT an electrical engineer. YOU ARE A STUDENT, lmao, I thought you might be a child and I wasn’t far off.

            Your German, correct? I fixed aircraft in Germany, and you are only a student. Ever work on 115 VAC @ 400Hz 3 Phase? Ever work on C-130 avionic systems? What about B-1’s?

            There is actually a lot of stuff I miss about Germany, too. Döner Kabob… God I miss those, they were my favorite. Oh and the German ice cream. Also the beer… I miss a good Dunkel.

            You know, the sad part about this interaction is that I think we may have been friends, if you didn’t come across so aggressive. A lot of your posts are on a German Arch community, which, well I’m running that with btrfs, snapper, hyprland, and quickshell. I intend to change to cachyos, I rather appreciate their optimized kernel.

            Regardless, keep studying you’ll be an electrical engineer soon.

You had the most childish reaction i saw on here for a long time.

              With what you wrote i woild bet that anny ee student that passes the first semester has more knowledge than you… and no i am not a student annymore i graduated with a bachelors end of last year :)) Also if if i still were a student that would still make me a lot more qualified than you, because before going to uni i had a 3,5 years apprenticeship as mechatronics technician that made me a “elektrofachkraft” so i am qualified to work with industrial systems up to 1000V.

              If you really worked on all those systems you said you did and dont know the basics about how voltage current and resistance relate to each other it would be very sad…

Maybe you fixed all the equiptment? But you sure as hell didnt fix it by understanding circuits or electronics if you think 12v can harm you by touching it only because the supply is capable of high apperage (with the source “movies” none the less). “Fixing” stuff is in this day and age also not something that shows you understand how something works. In most industries and i would guess the military it is the same, fixing means “i replace module xy because the error code says so / untill it works”.

                  I also dont feel like responding annymore because the next message propably will be another goalpost push on why i dont think you did x or y when it was never about that…

      Step one of leaving a light on for a month might be a big hole in this plan those days. Electricity diff would be like a dollar or 2 at worst because bulbs are like 12 watts now. If the temperature went up by a couple degrees one day the AC would make it fluctuate just as much as that and you wouldn’t even notice on a bill

        The screws will melt and probably start a fire with the wood they are screwed into. The pole might get hot too from the current that goes through the fasteners but most of the heat would be in the screws and the fasteners and dissipate before it reaches the pole. Hardly any current will flow through the pole itself.

      You can short the terminals on a car battery with your body with no issue (there’s a theory that that’s why you see it in movies so much - if anyone actually tries it the studio isn’t giving them an idea that actually works. Same with duct-tape gags and chloroform), but it might melt the hardware and set the floor on fire which would be fun! What they should really do is connect a HV source and charge up the pole. Won’t cause any lasting harm, but hopefully it’ll convince them they drove a screw through a live wire.

              I’m aware - I very intentionally spared everyone the lecture on the mechanics of how this works because it is, on the whole, very boring. However if we really wanted to get into the boring technical details nobody but us cares about then yes, you are indeed shorting the battery, it’s just for a ludicrously small amount of current. Ohms law (I = V/R) gives us that.

                Thing is, you also called it “shorting” the battery. Usually a short is an unintended, unsustainable low resistance path.

                While your body may technically close the circuit, calling it a short makes it sound like an actual electricution risk. That combined with the unclear “no issue” usage made it pretty confusing, I thought you had no idea what you were talking about until I saw your reply.

I wouldn’t have done this were it a more technical setting, but this is a shitpost community - so I’ll just have to beg forgiveness for my imprecision. Fortunately, should anyone go to test this by fondling their car’s terminals, no harm will befall them due to my lack of strict accuracy in the description here (though they might get rebuffed by their car if it’s not in the mood).

      I mean, a car battery isn’t going to do anything even if you could complete a circuit. You can just grab the terminals on a car battery, 12V isn’t high enough to be noticeable on dry skin.

      You’d want to solder on the hot lead of an extension cord hooked up to 120 if you wanted to make sure they never touch that pole again.

      Disclaimer: don’t do this, it’ll probably kill.

          You would have to try pretty hard to kill yourself with a hotwire even if you had a heart condition. Like lay on your side on the ground and grab the hotwire so maybe the circuit went through your heart and not entirely followed the shortest path to ground along your side.

        I think there is potential for some non lethal zapping if done right (one terminal to the poles other to ground)

        Your skin is where most of the body’s resistance is, and electrocution / shock can occur at much lower voltages if applied internally/ to a cut.

        There’s an urban legend about a navy Electrical engineer stopping his heart by trying to measure his internal resistance with a voltmeter- he stabbed one probe into each of his thumbs and the portion of a single volt the meter uses to test resistance going across his heart was enough to cause afib.

        Now, with pole dancing, theres some potential, for a sweaty bikini to make contact with both an electrified pole and the interior of the dancer’s labia, conducting enough electricity to impart a noticeable shock.

        No matter the voltage though, I think the main problem is the body being part of the least resistive, or any, path to ground. Unless the screws holding the bottom of the pole also protruded through the downstairs neighbor’s ceiling, and you run the negative wire out your window and into theirs, connecting both ends of the pole to the battery…

          Even if you had wires on both ends of the pole, nothing would go into the person because the path of least resistance would be the pole. You would have to energize the pole and directly connect the person to the other wire in order to complete the circuit. Then the resistance of the human body becomes an issue, and using this paper as a reference, the worst case scenario of internal body resistance is ~300 ohm, and the threshold for immediate cardiac symptoms is ~100 mA.

          Then, 12V / 300 ohm = 40 mA. So closer than I’d like, but probably not fatal even in the absolute worst case scenario where there is no electrical resistance provided by the skin and a direct electrical path through the heart.

            I was thinking no fatal but feel able. Seems like I was way overestimating the ability of sweat as a saline solution conductor to pull power away from the pole and create a shock on the bits below though.

      For someone to get electrocuted, the current needs to flow through their body. Electricity always follows the path of least resistance, so there’s basically no way to do that from upstairs.

      If you attach both terminals of the battery (or a stripped extension wire) that wouldn’t do it. Assuming the pole is conductive, the electricity would just go into the screws, into the pole, across to the other screw and out. If the pole isn’t conductive it would probably do nothing at all. Maybe the floor is conductive, in which case it would go into the screw, through the floor/ceiling and out the other screw. There’s just no way to do it where the electricity flows from a screw, down the pole, into the body of the pole dancer, then somehow back out and up to the battery.

      Even if the person who owned the stripper pole wanted to electrocute themselves it would be difficult. Assuming the pole is conductive, if you attached one electrode near the ceiling and one near the floor, the electricity would just flow through the pole. It wouldn’t make a detour to go through the body of the pole dancer. You’d basically have to clip one side of the battery to your toe, the other side to the stripper pole, and then grab the pole with your hands. And, even then, it might not do it – you’d have to have sweaty hands and toes to make the path through your body conductive.

      I really hate the movie trope where people can get electrocuted by stepping into a puddle that has something electricity-related in it. It’s almost as bad as the trope that you get blasted backwards if you’re hit by a bullet / shotgun blast.

        so there’s basically no way to do that from upstairs.

        Incorrect.

        stripper poles are tubes and spin on bearings. follow these instructions and you can most certainly electrocute someone with one.

        1. drill a hole in the center of the floor that feeds directly into the “tube” of the pole.
        2. strip 2-3 feet of a solid core copper wire(10-3) to bare copper and kink it into a zig-zag shape that gives it enough width to touch the pole inside.
        3. feed the wire down into the tube until it stops
        4. connect that wire to common
        5. connect the bolts to live
        6. turn the lights on when you hear them on the pole
        7. zap!

          Does this work by creating a resistance in the wire (zig zags) so that anywhere you touch on the pole causes you to become the path of least resistance? I’m just having a hard time following but it intrigues me

            🤣 I really didn’t. I used to be a contractor and just understand how this stuff works.

            best way to not kill yourself is to know the thousands of ways to die.

          What makes you think that will work? That sounds like a very complicated way of just connecting the common to live with no human in the loop.

            Ikr, this at least makes the pole get hot because current is actually running through part of it.
            But at no point is a human part of the path of least resistance for the electricity.

            the gauge of metal the pole is made from is pretty thin. on top of that, it’s very likely to be made from aluminum.

            if electricity follows the path of least resistance, it would be through the person.

            1. 70% water
            2. large contact surface
            3. typically two points of contact from lower to upper. this is why you need to lower the wire as low as you can down the center of the pole with most of the insulation still on. you want to force the electricity to travel as far as possible until someone touches it.

              Ok, you’re still failing here. The water content of a human body is irrelevant. A large contact area is irrelevant.

              Let me make it easier for you. As I’m sure you know, to be electrocuted an electrical current needs to flow through someone’s body. What part of the neighbour’s body is the current going to enter, and which part is it going to leave?

      Nah, that wouldn’t. But if you connected just the hot line (right eye of the outlet smiley face) that would do it. Wouldn’t recommend it because you could kill them by electrocution or kill even more people with a fire.

    Sure, if you want the battery to short out and start a fire.

    Cut the tips off then drill out the screws so they break off the next time they use it

      Seriously though, this is def something you take up with the landlord, the fines and payment for the repairs alone will be punishment enough.

      My browser history now includes several Amazon listings for stripper poles.

      I have learned that:

      1. The listing ALWAYS calls them “dancing poles” but Amazon knows what you mean,

      2. About half of them are sold as “unisex” even though all of the photos of them in use show women,

      3. Only some require drilling into the ceiling. The few that do ship with screws or lag bolts that are approx. 2 inches in length and come with drywall anchors.

      So, if installing any of the poles from Amazon’s first page of results, your floor would have to be approximately 1.5 inches thick.

      If the downstairs apartment had no ceiling treatment and you looked up at joists and subfloor, you might get here if she decided to attach between the ceiling joists. In a typical residential structure with a drywall ceiling, you’d need lag bolts some 10 or 12 inches long to reach through the plate of the pole, 3/4" of drywall, 8 or 10 inches of floor system depending, 3/4" of subfloor and 1/2" of flooring.

      I got drill bits that can go pretty deep. The reason this shit doesn’t happen to professionals like myself is that I am scared of electricity and power tools and have no clue what I’m doing and have people do it for me.

      That wiki says it’s common in hospitals and labs. Interstitial space is not the same as a floor cavity.

      Also

      The heights of these spaces are generally 6 to 8 feet (1.8 to 2.4 m) and allow easy access for repair or alteration

      So yeah not common in a residential building.

        This bit has nothing to do with America, we don’t have that kind of space between floors in residential buildings, either. You have plenty of real things to shit on us for, but this isn’t one of them.

    • Did you mean kV? I don’t know if 40kHz is high enough, but I know at some point it doesn’t even shock anymore, just burns. Hence you can take a screwdriver in your hand, and get it close to high frequency Tesla coil / slayer exciter circuit (not that I know the difference) and have it flow through you no problem, just if you touch the spark directly it burns.

    Frangible nuts. Get the load onto the nuts instead of the floor/ceiling. Wait until the neighbour is in the middle of something very physical, then blow the charge allowing the bolts (screws) to slip.
