These cordless anti-static bracelets are actually useful, they are used in various factories when it's too risky for workers to be constantly tied to earth. Usually there is small ground plane within the reach of a person, and You are supposed to touch the ground plane with this bracelet from time to time or before installing certain components that are static sensitive. I hope that @ElectroBOOM will do more research before posting similar video in the future.. It's very easy to make fun of something but much harder to admit of being wrong ;) And the resistor is there to eliminate the 'zing' ;)
By the clock on the left you can see: 1- He started the video around 11:15 AM 2- And finished around 3 PM 3- Total time: 3:45 Minutes Approximately 4- 3:45 / 7:58 = It takes him about 28.125 Minutes to make 1 minute of the video and this does NOT include editing time. Thanks Dude.
I've read that alpha-emitting radioactive materials (usually Polonium-210) are sometimes used to wirelessly dissipate static from materials in industrial environments. So maybe if you covered your body with a radioactive isotope you'd have a personal wireless anti-static solution?
You see the first 'wireless' anti-static wrist straps came to be due to a miscommunication. You know how chinese sellers can be, english is not always their specialty. It was just supposed to be an anti-static wrist strap supplied without the wire - for those who already have a wire to connect to you know. They even included the resistor inside the strap, you just had to connect it. But alas it was lost in translation... and now here we are.
This reminds me of a quote from bitwit's review of the verge pc build guide: "That isn't a anti-static wristband, that is a live strong bracelet" (In a Chinese accent of course)
@@Milolan I bet he not only spent a significant amount of time there but also didn't leave empty-handed 😜 I bet Mr & Mrs ElectroBoom had some fun that night, and many nights to come... Pun very much intended 😂
in the beginning of the video I was thinking he was just going to buy a leather bracelet and put a bunch if nails through it (with the head of the nail towards the skin of course)
@@ElectroBOOM Yup, that confirms that they're not coated. But I wonder whether a different, pointier design, with more spikes, might work? Still, this test seems to disparage that . Fred
@@gutsovernuts3553 To be fair it's been in use for way longer than it's been a fetish. Around 4,5 millennia to be precise, dating back to the Sumerians as a protective charm. They only really gained ties to sex in the late 19th century because a very thin variant was popular with prostitutes.
Reminds me of when I worked on communication towers, we had a grounded rod we called the Jesus stick. After shutting down the power we would have to make sure the transformers were dissipated and when you touched a transformer you thought should be de-energized with the jesus stick and you got a loud pop and arc you were left saying Jesus!

We should all try this experiment. For Science!!! And should _anyone_ think you're a freak wearing that pointy hat, just let them know you're doing a scientific experiment about electricity and they sure will understand, turning their previous suspicion into awe.
The Verge apparently has a fully working cordless anti-static bracelet, as evidenced by their PC build video. If you ask nicely, they may let you borrow it.
@@MaximC He litteraly had a rubber wrist wrap, and called it an anti static bracelet haha. The whole video is a joke. Search ''The verge 2000 dollar PC build''
Amin, I see. Yeah, what a joke, but I feel bad for the guy in the video, I think he suffers from some learning difficulties or something like that, and people were and are unnecessarily mean to him - not cool (I'm not talking about constructive critics). 😞
I love how the real ESD wristband and having bare feet (bear feet) worked exactly how it should. It's great to see when these things we've learned actually work in real life.
Yes, but you have to be careful using bare feet, i once pulled out my pc and turned it around afterwards, my fingers touched the psu outlet while reaching behind it and that gave me a big zap. Better to insulate yourself from the ground and use one of those wristbands instead to be safe. I have to admit I just hold the case once in a while to discharge myself, which doesn't prevent this either.
Did you make sure the spikes were 100% metal and not coated with a material for example galvanised steel? If so grinding the coat away could change the outcome.
my first thought was chrome plating or even paint. i was actually thinking if maybe the type of metal used could effect the discharge. IE maybe it would work with a different metal.
Wire up a can of Corona beer to ground, with the 1Meg resistor, and take a swig before handling ESD sensitive devices. That's Corona discharge done the right way.
I dunno, something "Supercity" or so along the lines. Where the guy responsible for the comic couldn't even keep his own deadlines and all we get was some guest drawing, which was better then the actual comic.
That's actually really interesting. The idea that metal spikes would help was a reasonable hypothesis, so it wasn't immediately obvious to me if this would work or not. Great experiment, thanks!
In theory it seems that spikes of sufficient pointiness and longness should dissipate the charge, but in practice they might have to be much longer and pointier than what would be considered workable. I have no idea what the math would be on that.
@@falahati oh, that makes a lot of sense for aircraft. You wouldn't want one getting all frictioned up to tens of thousands of volts and then touching down. Also, if they didn't have some way to mitigate the charge, it would probably complicate mid-air refueling as well. Now I'm curious about spacecraft in orbit.
@@tom_something Well it is super practical in their case too, aircraft moves very fast through the air and it helps a lot with dissipating static charges from the pointy needle at the edge of the wing. About space crafts read here: en.wikipedia.org/wiki/Plasma_contactor
Junk is something that you don't need now but may need in the future, so you store it in your garage until it's overflowing and can't park the car inside.
Man! I am one of those who are suffering with this static shock all the time especially in winter no matter with anything, whether it's metal, glass, other people etc. I also couldn't open my eyes to look at you getting zapped here in this video coz I can feel your pain. You're so brave man!!
I often get shocked around the office, so I started keeping either a rivet or metal coffee mug on my desk (isolated). Whenever I get up from my desk, I pick up the coffee mug or rivet without getting shocked, and touch that to a grounded surface. Sort of works like a wireless bracelet, but you have to manually ground yourself frequently. Also, with the rivet, if the build up is strong enough, I can still feel the discharge, but the mug seems to do the trick 100%.
2 things. 1) I would have loved to seen the look on the sales person when you walked into the store. 2) Just what and the HELL did your wife say when you walked in with those?? Loved the video as always PEACE:)
My old Mazda Protege had a spot to touch to discharge static next to the door lock. I've never seen that on another car. Of course, I never used it, and when I got new tires I'd get zapped getting out of the car.
Just hold your key firmly and touch the door after you get out. The larger surface area will dissipate the charge painlessly even when you see the spark between the key and the door. Oh wait, I've got keyless ignition. Hmmm.
FYI you actually don't want to ground the ground strap. You want to connect it to the board you are working on so you have the same electrical potential. For example when working on a computer motherboard you want to connect it on a metal part on your case (or a ground point like a screw hole, if not in a case). It is the difference in electrical potential that makes high voltage (and current). Not by magically connecting to ground. Edit: great video as usual. Keep up the great work 👍 (sidenote: It is true if you have your board connected to ground that then you connect the ground strap to ground, but then it is the same as what I wrote above)
But then havent you only potentially dumped a bunch of static in to what you are working on? Sure you may then be at the same potential, but there is still a charge built up there which has no where to go. I mean, surely decades of electronics industry cant be wrong when they connect their static straps to ground?
right, if you start with a charge and touch your board, you're going to discharge into your board. there's nothing magical about ground, it can be any large piece of metal that your static charge can redistribute itself into.
@@matthollandsf the board can also be charged (but not as likely as you being charged). So if you are grounded and you touch your charged board, then it the same if you are charged. That is why I wrote, that you have to have the same electrical potential as the board. Otherwise you induce a electrical voltage (and current BY LAW, [ohms law]). If you have a anti-static mat, then connect your armband and your mat to common grounding point. That was the way I was tough when building/repairing computers.
this is starting to feel like a chicken and egg problem. you have to assume your body is charged before you start, then you can decide whether its safer to discharge to something that isn't your board, or to discharge to your board, possibly damaging it. if the board is getting its own static charge somehow i would see that as a separate issue to be handled in its design/use.
I second that. You should discharge to the environment ground. If you have a big charge on you, and only connect the bracelet to the mat and put the board on the mat, you’re doing exactly the same as touching it directly.
Nah. Something marketed as a "Bluetooth water hose" might actually give you the ability to control water flow from your phone, monitor flow rates or even take other measurements such as temperature, pH and sediment PPM.
Nice I always wanted to try that :) a quick remark the obly way to discharge your bidy through spikes is via partial discharge. A single partial discharge from a spike in air ( corona discharge) will have around 10 pc and you will have around hundrets of these disscharges per second ( depending on the voltage). As your capacitance againt gbd should only be a few nF, it should have a sign. Effekt. These spikes howerver are not pointy enough. When we prepare needles for coronadisscharge experiments in the lab we usually chem. Edge needles down to 10 um tip radius. If schould plan to rrpeat this i would suugest a self made braclet with four syringe tips, those are usually as pointy as it gets....
The amount of static electricity that wireless antistatic wristband discharges is the same as the amount of brain cell anyone blatantly believe in such thing without further thinking.
Bro your content is fantastic. 100-percent technically correct. And you are hysterical as well. I recently saw your perpetual-motion stuff. I got sucked into a couple of discussions with people who have no idea about physics and had to break away from that it was giving me a headache. Again please keep doing what you're doing it's fantastic
Just an idea, what if you used a diode and capacitor to draw the charge away from your body? You could possibly go further and have a small incandescent bulb on it that would use the energy by converting it to heat and light.
When I first started watching this channel I watched it to see someone get hurt and I never knew I was learning until I had to explain to someone what a full bridge rectifier is 😂
For many years I’ve had a static discharger. It cost £1 from Poundland and it works. I often needed it when driving an old, solid tired mobility scooter around school where I was a teacher. It is about 2” llong and is a glass tube with brass caps on each end, one of which is held and the other which has a blunt point to touch on a grounded object eg steel handrail. It has some sort of resistor inside attached to the caps. In certain weather my shell suit trousers build up quite a charge and I can run the discharger down it giving a mini fireworks display 🤪
@@johnfrancisdoe1563 Thank you. I will get started with this! Safety first of course, but if you hear about a new superhero wearing Timberland shoes and a rabbit fur trench coat you will know who it is. ;D
Wear a metal ring suit like those guys that play electric guitar by electrocuting themselves (the electricity "bends" around them to keep them from being electrocuted to death from the thousands of volts).
Loved it! A few weeks ago I was in an exhibition and the floor was all covered with carpet. Even with my ESD safety boots on, I got shocked a lot of times touching metal structures connected to ground. Shouldn't the boots prevent me from this effect?
@@whyshouldipickaname right, but the boots should protect my feet to get charged from the carpet, because I wasn't touching it with nothing but my boots.
@@pedromms8908 for what I know ESD boots are designed to make contact with the floor with a series resistance in the Mohm range. This prevents your body from building up charge as it constantly dissipates it to earth. But if the floor is carpet they do the opposite, they make it easier for your body to pick up charge by rubbing against the carpet
I don't know anything about electricity, but couldn't you make a wireless one if there was some kind of device that absorbed and stored the static energy? Like a battery or a capacitor, maybe a miniature Leyden jar?
Henry Chavez A leyden jar is basically a capacitor,even if you make a rc series that connects you can only use potential difference to store charge (you need some kind of emf) and even if you could They wouldn’t even exceed a few microfarads so hardly any charge would be stored
Wish everyone Merry Christmas and may all your dreams come true. I wish you all the love, luck and success in the coming year. I once again wish you and your family a very Merry Christmas and a happy and prosperous new year. Have a blast this Christmas!
how to avoid static discharge (when opening a door or before touching bare metal): touch a painted door surface or something similar which has a great surface area. resistive discharge occurs, preventing immediate discharge which would cause a painful arc. in my experience, coated metal will not provide a resistive discharge, a painted metal object with a large surface area usually does though.
The amazon reviews are funny. I found one saying it eventually stores the energy of a lightning bolt, and that you need to take it to a "professional" to discharge it.
I built an anti static bracelet once with a capacitor and a neon bulb. The bracelet would conduct static electricity into the capacitor. When the capacitor reached it's voltage, the neon bulb in parallel circuit would trigger and turn on using up the static electricity, and removing it from my body. Depending on how much static electricity is available, depends on how fast the neon bulb turns on and off. I thought about creating a similar device that I could implement on a some type of storage box to store sensitive electronic equipment inside and protect it from static electricity. Theoretically you can also build an anti-magnetic housing the same way using copper wire windings, capacitor and a neon bulb. It would be especially good for storing magnetic disc hard drives. Forgot to mention, there was a diode in there somewhere.
keco185 This and air ionizer make the air more conductive so that charges dissipate better. When I don't want sust to stick to something I'm working on, for example a LCD screen that I have removed the front panel from and I don't want to close it only to find out there's dust right in the middle of the picture, I use both. But if it's really sensitive or expensive, I use wired bracelet as well, and if not, I just grab the ground of the circuit first so it's at the same potential as I am.
You could discharge static cordlessly if you wore a bracelet that emitted strong ionizing radiation or if you held a blowtorch or a metal bodied kerosene/paraffin lamp where the flame would dissipate the charge. Holding a candle wouldn't work unless it had conductive wax.
I noticed that you didn't try the cordless anti-static bracelet on the Van de Graaff. Suspicious... maybe somebody is in the pockets of Big Corded Anti-Static Bracelets.
im not pleased with the semi-scam they are pushing. those tricks are done in hope that you'd forget to unsubscribe and will take you a few months to notice this drain in your budget. especially if you have 2 months free, watch 1 video, leave and forget about it and then forget to cancel it
I need this! I wrap a LOT of pallets on an automated pallet wrapper and I'm right next to these very grounded transformer battery charger boxes so... I've had a visible shock run off the tip of my shoe 6" through the air to a metal ground. I was joking around with passer-by "It keeps me on my toes!" It's been VERY dry here in the midwest past couple weeks. I'm trying to get one of the mechanics to make me a discharge wand. a grounded metal tipped wooden dowel or something.
@ElectroBOOM At 1:03 you show a Bracelet with a resistor in it. I have one I use a work. Mine has a metal bracelet. If I need to touch a metal part that will shock me with static then I pick up the bracelet (I don't even put it on, I just hold it) and touch the metal screw on the blue plastic box onto the metal part. I think that there is an air gap between the screw and the resistor inside the blue box and that is were the spark happens. The result is that I don't feel the shock of static. It works for small static that I find annoying. Not sure what its limit is for larger shocks. You should test it.
To everyone saying use a capacitor/battery to "pocket" the charges, here is an explanation. 1. Your body literally IS a capacitor. Charges accumulate on human body due to it's capacitance to the environment, and you receive a shock when you short the charged capacitor, that is your body, to the ground. Ok, you made a "Wireless Bracelet" with a capacitor, How does it work? You have to put the capacitor across a potential difference to charge it. Fine. One lead touching you and the other can just stay flying in the air. (This is exactly how your body, acting as a capacitor, picks up charges btw) When getting charged, the capacitor AND your body get charged. The capacitor is NOT pulling charges off of you and bringing you to GROUND potential, it is rather getting charged ALONG with your body. And that will discharge when you/the capacitor touches ground. So much to prevent ESD I guess. 2. A battery is a just capacitor, which holds charges as chemical energy instead of electric field. Same explanation applies. Rather it would be even more difficult work with because of higher internal resistance which would not accept the charges as readily.
