WEBVTT 00:00:00.120 --> 00:00:06.180 ow it is never fun to be on the business 00:00:03.899 --> 00:00:13.340 end of an unexpected shock from a door handle ah light switch or 00:00:10.519 --> 00:00:18.840 masochistic electrical engineer as many of you know this is called 00:00:16.160 --> 00:00:22.140 electrostatic discharge or ESD and it can happen when two differently charged 00:00:20.820 --> 00:00:25.980 objects are brought close enough together to overcome the insulating 00:00:23.820 --> 00:00:30.300 properties of the air between them it takes a discharge of at least 2 000 00:00:28.199 --> 00:00:33.600 Volts for us to feel a zap but as little as a hundred volts could potentially 00:00:31.740 --> 00:00:37.020 damage sensitive Electronics that's where these come in anti-static 00:00:35.160 --> 00:00:40.800 wristbands are designed to prevent this buildup of static on your body but if 00:00:39.540 --> 00:00:46.140 you've seen more than a handful of our videos you'll know that we're pretty lacks about actually using them because 00:00:43.500 --> 00:00:51.840 being tethered is kind of annoying there's a solution for that this 00:00:48.719 --> 00:00:53.940 actually bees Wireless anti-static 00:00:51.840 --> 00:00:57.480 wristbands are supposed to keep you grounded without connecting to the 00:00:56.579 --> 00:01:03.840 ground it sounds too good to be true which is 00:01:00.420 --> 00:01:05.820 why we asked Medi from electroboom to 00:01:03.840 --> 00:01:10.580 help us find out if these really work I'm here to help Linus yeah last time 00:01:10.700 --> 00:01:16.560 I'm here to test lines I mean 00:01:14.100 --> 00:01:19.979 not test him test with him whatever he wants to test a little this is the roll 00:01:18.780 --> 00:01:22.939 the clip okay 00:01:23.520 --> 00:01:28.080 don't worry I won't feel a thing and you 00:01:26.520 --> 00:01:32.939 won't feel a thing with this gentle segue to our sponsor Asphalt 9 Legends 00:01:31.320 -->

already know this but the way these conventional anti-static 00:01:59.640 --> 00:02:06.600 wristbands work is pretty simple the inside of the cuff has conductive 00:02:04.079 --> 00:02:11.039 threads woven into the elastic which are physically connected through the Buckle 00:02:08.160 --> 00:02:16.260 to the snap on the outside with the cord snapped on and attached to ground 00:02:13.260 --> 00:02:17.819 there's a direct path to discharge any 00:02:16.260 --> 00:02:22.140 static charge that would normally build upon my body and a resistor in the cord 00:02:20.160 --> 00:02:27.540 protects you in case you accidentally come in contact with up to 240 volts by 00:02:25.020 --> 00:02:31.500 limiting the current to 0.5 milliamps but 00:02:29.160 --> 00:02:34.560 how do we know they actually work how can we test them 00:02:32.760 --> 00:02:38.220 before we get to our wireless options Let's test the traditional wired bands 00:02:36.900 --> 00:02:44.879 and make sure that we know what we're looking for there are a couple of things you're going to need a multimeter and an 00:02:43.140 --> 00:02:48.959 electro boom intuitively I would think a device 00:02:46.800 --> 00:02:53.340 that's designed to discharge static electricity would just be a wire 00:02:51.060 --> 00:02:57.959 essentially but when we do a continuity test on this 00:02:54.780 --> 00:03:00.000 there isn't meaning that no current is 00:02:57.959 --> 00:03:03.599 passing is my understanding Uh current is passing but it's so little the 00:03:01.560 --> 00:03:08.099 continuity doesn't show it continuity is made to test ShortCircuit pretty much 00:03:06.120 --> 00:03:12.420 right or very low resistances but right this guy has around one Mega ohmm of 00:03:10.680 --> 00:03:17.400 resistance in it which we can probably check with that to see if it's there I 00:03:15.000 --> 00:03:23.159 see okay well can we verify that yeah I guess we 00:03:18.360 --> 00:03:25.739 press and check the ohm and yeah 00:03:23.159 --> 00:03:30.840 let's see oh one Mega ohm exactly wow good job I fix it to two decimal places 00:03:28.140 --> 00:03:34.440 your resistor is exactly what you say it is we briefly touched on why the 00:03:32.879 --> 00:03:39.120 resistor is there it's to protect you from high voltage but why on Earth would 00:03:37.200 --> 00:03:43.200 I ever encounter high voltage when I'm wearing an ESD strap well the thing is 00:03:41.340 --> 00:03:47.640 that if we are working on electronics and accidentally touch live wires for 00:03:45.480 --> 00:03:51.060 example you don't want your body to be shorter to ground otherwise there will 00:03:49.560 --> 00:03:55.080 be a ton of current going through you and the one Mega ohm resistance in there 00:03:53.280 --> 00:04:01.319 is there to limit the current through your body got it so this is just in case 00:03:58.019 --> 00:04:03.540 I screw up not in case the laptop that 00:04:01.319 --> 00:04:08.519 I'm repairing something happens yeah well at the same time the electrostatic 00:04:05.540 --> 00:04:12.959 on your body is so small that one Mega ohm although it sounds too big it is 00:04:10.860 --> 00:04:16.680 enough to quickly dissipate the electrostatic hold on a second what 00:04:15.180 --> 00:04:23.960 you're saying then to quote There's Something About Mary is there's a chance 00:04:21.740 --> 00:04:28.020 out back to our conventional one for a 00:04:26.160 --> 00:04:31.680 second though we've already measured that the strap works but how do we know 00:04:29.820 --> 00:04:35.759 that the contact with me is good can we measure that well actually from what I 00:04:33.720 --> 00:04:39.900 understand even this strap even this band has a little bit of conductivity I 00:04:37.919 --> 00:04:45.120 mean everything is conductive for high voltage anyways so there is some stuff 00:04:42.479 --> 00:04:49.800 in there that even when I touch that my body loses charge how do we test it 00:04:46.860 --> 00:04:54.900 though oh we test it by charging you up with this thing which yes puts enough 00:04:52.680 --> 00:04:59.940 charge on your body and we can see if the charge goes away with that okay all 00:04:57.600 --> 00:05:05.180 right theoretically I am protected from your Contraption right now right 00:05:02.759 --> 00:05:10.919 do that well that was a long Arc that was nice 00:05:08.479 --> 00:05:15.780 but we don't want to use this do we you want to use this one fine one thing is 00:05:13.800 --> 00:05:20.520 that stuff I make are not made for production so hopefully it won't fail if 00:05:18.720 --> 00:05:25.520 it does fail I hope it at least fails in an entertaining manner that I can count 00:05:22.680 --> 00:05:25.520 on with you yeah 00:05:29.400 --> 00:05:34.440 okay it's alive it's really antsy 00:05:32.820 --> 00:05:40.860 now you can bring the back of your hand close to this thing and feel the charge 00:05:37.220 --> 00:05:43.560 whoa you get it good yeah 00:05:40.860 --> 00:05:49.620 okay so it's working then the the pantyhose is working 00:05:45.680 --> 00:05:52.560 there you go okay all right but how do 00:05:49.620 --> 00:05:56.880 we build up a charge on me then so should I be oh God should I be 00:05:55.500 --> 00:06:01.199 touching that because we're trying to demo that the 00:05:58.500 --> 00:06:05.220 ESD strap makes it so that I can safely be rubbing my feet around on the carpet 00:06:03.300 --> 00:06:08.460 and work on my computer right sure yeah okay well uh don't touch the computer 00:06:07.199 --> 00:06:12.840 first how much is it gonna hurt to touch that 00:06:10.620 --> 00:06:17.280 like if I touch it constantly and when you go close to it it hurts at some 00:06:15.660 --> 00:06:22.380 point you can't you can't put your hand on it okay that's really not encouraging 00:06:19.199 --> 00:06:24.240 the way here ow so I have to do it on 00:06:22.380 --> 00:06:26.539 purpose and then hold it there right yeah 00:06:28.199 --> 00:06:34.699 why do we collab with this guy 00:06:31.220 --> 00:06:34.699 because it's fun 00:06:38.340 --> 00:06:44.039 okay how fragile is it like can I just like 00:06:41.880 --> 00:06:49.319 go in there it's not made for production I already said that you're gonna destroy 00:06:45.720 --> 00:06:51.419 it just slightly touch it 00:06:49.319 --> 00:06:59.280 okay you can do it I believe in you 00:06:54.120 --> 00:07:02.660 I'm sweating right now I'm sweating okay 00:06:59.280 --> 00:07:02.660 damn it okay 00:07:02.900 --> 00:07:11.240 ah I can feel it I can feel it from here it just aren't to me from that far away 00:07:08.699 --> 00:07:11.240 okay 00:07:16.800 --> 00:07:24.180 there you go there you are oh yes yes 00:07:19.880 --> 00:07:26.759 okay now your body is picking up charge 00:07:24.180 --> 00:07:30.060 from that right and then if you touch your computer your computer is grounded 00:07:28.440 --> 00:07:34.039 right okay 00:07:31.800 --> 00:07:40.860 there is no discharge this ESD wristband works perfectly the 00:07:38.160 --> 00:07:45.800 initial discharge was high voltage low current right yes but then now that I'm 00:07:43.319 --> 00:07:51.419 touching it you said the voltage stays very low maybe close to zero even okay 00:07:49.139 --> 00:07:56.280 but whatever it is whatever voltage it's at it's very little current right and 00:07:54.419 --> 00:08:01.860 it's going through my ARM through my wrist strap through this 00:07:59.099 --> 00:08:06.660 cable and then into the ground into this doodad that we have plugged in 00:08:04.199 --> 00:08:10.500 that means this is all safe I could handle Electronics all day get me 00:08:08.639 --> 00:08:15.180 something expensive okay like this laptop this is fine what I'm doing right 00:08:12.720 --> 00:08:19.199 now right uh you better not disconnect your wristband 00:08:16.979 --> 00:08:22.979 from ground now because your laptop is not connected to the ground if you 00:08:20.400 --> 00:08:26.639 disconnect your wristband right now your body and the laptop will pick up charge 00:08:24.900 --> 00:08:31.319 when you put your laptop on the ground there will be a huge discharge killing 00:08:28.740 --> 00:08:34.880 your laptop in the process okay so take this before I take out the 00:08:35.279 --> 00:08:41.839 which means as long as the strap Works everything is good 00:08:39.180 --> 00:08:41.839 however 00:08:42.659 --> 00:08:49.440 okay you should you should stand on some plastic or so you can stand on that it's 00:08:47.279 --> 00:08:53.600 solid so that you actually pick up charge 00:08:51.300 --> 00:08:56.540 no Works 00:08:59.420 --> 00:09:07.560 let's say instead of a pantyhose running through a motor right I'm walking around 00:09:04.980 --> 00:09:16.980 on a carpet and then I'm standing still for let's give it a solid one two three 00:09:12.839 --> 00:09:18.240 four five steamboats I go and touch my 00:09:16.980 --> 00:09:23.459 computer ah and the hair stands on it my head there 00:09:22.620 --> 00:09:29.459 you go actually did your hair stand up when you were talking about it yeah I could feel 00:09:26.880 --> 00:09:33.300 it back here you probably couldn't see it but I could feel it now do you want 00:09:31.680 --> 00:09:39.380 to try the same thing with my magic wand that is more powerful I mean not really 00:09:36.500 --> 00:09:44.459 but I did so that's the way out here this looks like it does all kinds of 00:09:42.720 --> 00:09:49.620 interesting things yeah well I mean I wiped it this morning 00:09:47.220 --> 00:09:53.640 so you can use it it had some suit on it just don't put it 00:09:51.959 --> 00:09:57.060 in your mouth right burn marks and stuff so what have you done here this is a 00:09:55.980 --> 00:10:04.620 flashlight right yeah I bought a flashlight at some Home Depot yeah and I took the guts out 00:10:01.580 --> 00:10:08.220 and put my own Electronics in it pretty 00:10:04.620 --> 00:10:10.080 much and what is all of this are you 00:10:08.220 --> 00:10:14.640 stepping up the voltage or what are you doing here there's something here that 00:10:11.760 --> 00:10:20.100 makes what like eight to ten thousand volts ac and this is like a network of 00:10:17.700 --> 00:10:26.339 capacitor and diodes that yeah steps it up to over a hundred thousand volts 00:10:23.820 --> 00:10:31.320 it's it's not electrostatic discharge level even in the 00:10:27.980 --> 00:10:33.480 standards you test up to 20 kilowatts so 00:10:31.320 --> 00:10:37.320 100 kilowatt might be an Overkill but more fun 00:10:34.860 --> 00:10:40.440 can you just explain something to me real quick here I saw you take the cells 00:10:39.300 --> 00:10:45.600 out of this earlier they're just standard 3.7 volt lithium whatever so 00:10:43.380 --> 00:10:50.339 you but you you pointed at this and said blah blah blah something AC something 00:10:47.820 --> 00:10:55.800 yes okay can you explain that or is this an inverter of some sort or it is a 00:10:52.620 --> 00:10:58.519 circuit called a zvs it's basically an 00:10:55.800 --> 00:11:03.839 oscillator and a Transformer that increases the voltage of that oscillator 00:11:00.779 --> 00:11:06.660 the oscillator makes like uh three times 00:11:03.839 --> 00:11:11.640 eight 24 volts and then that 24 volt AC is Amplified through the Transformer to 00:11:09.180 --> 00:11:18.000 let's say 10 000 volts yeah and the 10 000 volts every step goes up to it's 00:11:15.180 --> 00:11:22.019 like 15 there so it should make 150 000 volts or something so you said your 00:11:19.920 --> 00:11:26.220 story keeps changing sir you said a hundred thousand now you say 150 what 00:11:24.360 --> 00:11:32.100 are you gonna hit me with I'm gonna hit you with this well the 00:11:29.220 --> 00:11:36.899 thing is that yeah no the high voltage runs like you can turn it on don't point 00:11:34.500 --> 00:11:40.860 it at any of your devices just point it towards the ground or something and just 00:11:39.000 --> 00:11:45.720 turn it on you will hear the electricity going out of it 00:11:43.320 --> 00:11:50.720 I don't want to turn it on well don't point it to your face you'll be fine 00:11:47.339 --> 00:11:50.720 here and my face too 00:11:51.240 --> 00:11:58.260 there you go that that that's the sound of electrons jumping out of the tip of 00:11:55.800 --> 00:12:03.300 it so explain to me what's happening there because we talk about static 00:12:00.720 --> 00:12:06.959 arcing through the insulating properties of the air right yes 00:12:05.339 --> 00:12:13.700 but this just jumps into the air what is it jumping to 00:12:10.940 --> 00:12:20.880 oh yeah I mean the voltage is so high that uh it pretty much tears the charges 00:12:17.760 --> 00:12:24.240 away from the air and it just charges go 00:12:20.880 --> 00:12:27.420 like how can we I mean it's even 00:12:24.240 --> 00:12:30.240 lightning right has to go Arc to 00:12:27.420 --> 00:12:35.880 something yeah but I mean that's what's happening with the lightning the charges 00:12:32.459 --> 00:12:38.040 start going go and until they say you 00:12:35.880 --> 00:12:42.720 reach a ground they create a channel that is ionized and then the whole thing 00:12:41.040 --> 00:12:46.320 goes through yes I see so this is basically pre-lightning so like if I 00:12:44.639 --> 00:12:51.180 pointed at you at a distance you will feel the wind coming of it out of it it 00:12:48.420 --> 00:12:56.940 creates a wind when I want to feel that actually 00:12:52.880 --> 00:12:59.459 nor do I I mean as long as you are from 00:12:56.940 --> 00:13:04.260 a distance you feel anything yet well maybe you should be 00:13:02.220 --> 00:13:09.180 connected to ground ground yourself man should I yeah because that way more 00:13:07.019 --> 00:13:14.339 charges you know more charges come toward you and and maybe I touch my the 00:13:11.639 --> 00:13:19.079 ground as well do you feel anything whoa is it coming good 00:13:17.519 --> 00:13:24.839 so that's the wind I was talking about the charges are running away from it and 00:13:21.959 --> 00:13:30.000 you know it ionizes the air to the same charge that is on the tip of that and 00:13:27.380 --> 00:13:34.100 they try to get away from each other because they are the same charges and it 00:13:31.500 --> 00:13:34.100 creates a win 00:13:34.560 --> 00:13:40.440 point you stand on that thing or do you want to show that actually 00:13:38.519 --> 00:13:44.040 that what are you standing on yeah sure it's a milk crate because everyone on my 00:13:42.660 --> 00:13:49.019 crew and everyone who comes to visit likes emasculating me 00:13:47.220 --> 00:13:52.320 and hold this uh 00:13:50.279 --> 00:13:56.040 touch a ground with it basically touch the tip to a ground okay 00:13:54.959 --> 00:14:01.579 um and turn it on disconnect it from the 00:13:58.620 --> 00:14:01.579 ground and then turn it off 00:14:01.800 --> 00:14:09.600 so turn it on now yeah keep it on or you can already hear you 00:14:07.320 --> 00:14:14.700 discharging to something don't have your hand too close to that thing 00:14:11.399 --> 00:14:16.620 wait am I charged now a little bit I can 00:14:14.700 --> 00:14:24.200 hear you the charges are running away from you oh yeah you were to 00:14:20.360 --> 00:14:27.360 wow now I am charged damn it 00:14:24.200 --> 00:14:30.240 wait why am I charged 00:14:27.360 --> 00:14:34.320 well this handle is ground of this thing and that side is the output high voltage 00:14:32.579 --> 00:14:39.600 whatever is it a negative or positive I don't remember but yeah so so it it is 00:14:37.380 --> 00:14:44.180 change it's moving the charges from your body to the ground so you get charged so 00:14:41.579 --> 00:14:48.560 charge yourself so what whoa 00:14:46.019 --> 00:14:54.240 whoa holy this ground wire 00:14:51.420 --> 00:14:59.040 did you see the actually like oh do you want me do I 00:14:56.519 --> 00:15:04.199 have to hold the button I only pressed it yeah if you press it once it charges 00:15:01.139 --> 00:15:07.160 you to some extent that wire like 00:15:04.199 --> 00:15:07.160 attracted to me 00:15:09.000 --> 00:15:16.920 yes don't let that wire get too close to your part okay okay and what are we 00:15:14.760 --> 00:15:21.060 testing now what was the point of this so now that you're charged you can let 00:15:18.779 --> 00:15:26.100 go of the ground there so just yeah now you're completely 00:15:23.459 --> 00:15:29.940 floating charged okay without a strap and now with that if you touch any 00:15:28.019 --> 00:15:34.820 Electronics you will discharge to it and here you can touch your computer now 00:15:31.320 --> 00:15:37.440 probably well I heard it 00:15:34.820 --> 00:15:42.320 there you go okay so what do I do what do I attach it to I touch it to not 00:15:40.139 --> 00:15:48.120 yourself okay so now I can put this down 00:15:45.899 --> 00:15:54.660 that's why you're already discharged far gone there's nothing okay 00:15:50.760 --> 00:15:57.180 it works yes strap wired strap Works 00:15:54.660 --> 00:16:02.880 which means that even though Maddie and I showed last time that ESD discharge 00:16:01.079 --> 00:16:09.380 onto a computer component won't necessarily kill it immediately 00:16:05.579 --> 00:16:12.480 um we know that companies like Intel AMD 00:16:09.380 --> 00:16:15.019 NASA for that matter follow these safety 00:16:12.480 --> 00:16:19.680 protocols because particularly during manufacturing these components can be 00:16:17.519 --> 00:16:23.760 more susceptible to this kind of damage and that's why the industry has 00:16:21.600 --> 00:16:28.920 standards for what these protections are supposed to look like for example this 00:16:26.399 --> 00:16:34.100 little guy right here from Desco whoops is a validation tool for making sure 00:16:31.560 --> 00:16:39.540 that your ESD strap is working without needing one of these though thank you 00:16:36.300 --> 00:16:41.579 very much whatever all you have to do is 00:16:39.540 --> 00:16:46.440 plug it into the wall then plug in your anti-static strap either directly or 00:16:44.040 --> 00:16:51.000 through an extension like this that you can then clip onto your ESD safe 00:16:47.940 --> 00:16:53.160 workspace and then all you need to do is 00:16:51.000 --> 00:16:59.100 touch this right here and it says test good that means that the resistance of 00:16:55.800 --> 00:17:00.660 your ESD strap is between 850 000 ohms 00:16:59.100 --> 00:17:06.179 and I think what was it about eight Mega ohms or something like that which is the 00:17:02.459 --> 00:17:08.760 NC standard with all of that in mind no 00:17:06.179 --> 00:17:12.299 I mean my way is more efficient quicker and it's a little cheaper for yeah it is 00:17:11.280 --> 00:17:18.419 actually cheaper this thing is shockingly expensive and not useful for 00:17:15.660 --> 00:17:26.160 testing all types of anti-static straps but with the magic wand let's talk about 00:17:21.900 --> 00:17:29.540 these if you don't have a wire coming 00:17:26.160 --> 00:17:32.160 off of it to plug into your ESD tester 00:17:29.540 --> 00:17:36.480 how can you validate if it is working correctly that's where the magic one 00:17:34.559 --> 00:17:40.020 comes in that's what I'm talking about this is this baby is good yeah that's 00:17:38.340 --> 00:17:43.620 actually the reason this collab got off the ground because we were trying to 00:17:41.460 --> 00:17:49.320 figure out how on Earth to either validate or debunk these things yeah 00:17:46.980 --> 00:17:53.760 what is our test the test is you wear that you charge 00:17:51.360 --> 00:17:57.539 yourself you charge discharge I mean you touch an electrical component or 00:17:55.500 --> 00:18:02.780 whatever and see if you survive that's the test basically no I'm making you do 00:18:00.059 --> 00:18:02.780 a test too though 00:18:04.280 --> 00:18:11.280 no I think I've suffered more than you today one of us is gonna do the bro 00:18:09.179 --> 00:18:15.179 anti-static and the other is going to do the made in Japan Live Strong bracelet 00:18:13.080 --> 00:18:19.039 which one do you want does it even matter for sure I'll go with the anime 00:18:16.799 --> 00:18:19.039 one 00:18:24.419 --> 00:18:31.919 oh this is stupid what is in this piece of plastic even it 00:18:30.480 --> 00:18:36.539 looks like there's some little metal like uh like kind of frag like dust or 00:18:34.860 --> 00:18:42.720 powder or something in there it looks more like glitter really looks 00:18:38.700 --> 00:18:45.179 like a joke bro he's on bro 00:18:42.720 --> 00:18:48.179 okay does it have to be that one what about that one that one doesn't look as 00:18:46.740 --> 00:18:53.640 threatening we learn by pain but wait wait wait hold 00:18:50.820 --> 00:18:58.679 on hold on because this is not realistic so we're not really giving this a fair 00:18:55.380 --> 00:19:01.320 Shake unless we give it a more realistic 00:18:58.679 --> 00:19:06.419 charge right well I mean yeah sure because that I mean that even managed to 00:19:03.360 --> 00:19:08.780 zap me through this thing right 00:19:06.419 --> 00:19:14.100 oh fine I'm trying to see if your hair is rising 00:19:11.460 --> 00:19:23.059 or not no not too bad are you charged at all oh yes your charge good 00:19:17.640 --> 00:19:23.059 I mean spoiler but um 00:19:25.260 --> 00:19:28.039 ah 00:19:28.820 --> 00:19:34.380 it did discharge okay hey you have The Wristband on you so you should be fine 00:19:33.179 --> 00:19:41.640 yeah damn it just do ah okay 00:19:38.880 --> 00:19:47.160 good okay you can turn it off now I can feel the hair Rising on my ARM 00:19:43.980 --> 00:19:50.100 good raising excuse me now your body has 00:19:47.160 --> 00:19:56.539 theoretically this is helping I'm gonna give it like five more seconds to 00:19:52.460 --> 00:19:58.980 dissipate into the thing into this house 00:19:56.539 --> 00:20:04.260 don't come closer oh that's not a good sign 00:20:02.220 --> 00:20:09.240 ah not a single electron left your body it 00:20:06.900 --> 00:20:12.240 seems through that thing at least if you have other pointy Parts on your body you 00:20:11.160 --> 00:20:18.720 could probably run okay well let's see if yours works oh you could have started with your hand on it 00:20:16.080 --> 00:20:23.940 there you go it's done I don't have any hair to raise on my head so 00:20:21.120 --> 00:20:29.460 okay I mean that seems probably pretty good okay now we let the 00:20:26.700 --> 00:20:35.220 country of Japan do its magic I can hear him from here 00:20:31.559 --> 00:20:38.640 oh it's it's my wires see oh it's his 00:20:35.220 --> 00:20:40.679 his lav wire is grabbing the table yeah 00:20:38.640 --> 00:20:44.760 it's like it's touching those wires that's where you are hearing it thank 00:20:42.660 --> 00:20:47.480 God they have some insulation on them ready 00:20:51.980 --> 00:20:57.080 okay ready oh 00:21:05.840 --> 00:21:10.799 that was a lot even even you touching my 00:21:09.179 --> 00:21:15.120 butt didn't discharge it oh I didn't touch I just got close and it was just 00:21:12.419 --> 00:21:19.500 it was leaping across I felt something leaving me so 00:21:16.820 --> 00:21:24.179 yeah so yeah there you go the Japanese wristband Wireless wristband was is it 00:21:22.500 --> 00:21:29.159 still worth testing with this one uh sure okay 00:21:26.059 --> 00:21:30.240 oh okay let's do it all right let me 00:21:29.159 --> 00:21:35.820 move this thing away who knows maybe it'll work even better with higher voltage 00:21:32.840 --> 00:21:39.720 whoa I can feel myself powering up I held it for a couple seconds don't put 00:21:37.860 --> 00:21:46.020 it down you may discharge yourself to something oh I see 00:21:42.120 --> 00:21:50.000 selected oh did you catch that spark 00:21:46.020 --> 00:21:50.000 David I bet the editor will have it 00:21:53.820 --> 00:21:58.679 let me see if I whoa I won't touch you what if I'm close to you I need to do 00:21:57.419 --> 00:22:05.720 that why ah probably you'll feel something 00:22:03.140 --> 00:22:10.280 what are you doing what are you doing why are you doing 00:22:07.980 --> 00:22:10.280 this 00:22:11.299 --> 00:22:16.520 but we are going to both her my hair's standing up oh yeah 00:22:16.700 --> 00:22:25.080 we should have a video of your hair that is raised and as soon as you touch it 00:22:21.980 --> 00:22:26.580 drops to zero yeah just okay 00:22:25.080 --> 00:22:30.380 yeah shake your oh there you go yeah yeah yeah it went up this time yeah 00:22:32.600 --> 00:22:39.600 okay all right your turn your turn I don't 00:22:37.919 --> 00:22:45.600 have hair though team Japan no you don't have to do the hair thing I just want to see if the Japanese one works better 00:22:42.000 --> 00:22:49.380 okay fine so-called made in Japan 00:22:45.600 --> 00:22:50.940 it's still there I feel it Japan come on 00:22:49.380 --> 00:22:53.419 ready no 00:22:53.460 --> 00:22:56.460 okay 00:22:56.940 --> 00:23:01.740 so what is their claim with these things 00:23:00.240 --> 00:23:05.039 should we take it apart and see what's going on here I didn't I really like to 00:23:03.900 --> 00:23:09.120 see what is in these Japanese things with this glitter bar at the bottom okay 00:23:07.500 --> 00:23:14.460 so we'll use this one on the made in Japan thing to get it apart and then in 00:23:11.640 --> 00:23:17.880 the meantime oh yes I also have we got you one of these already right well oh 00:23:16.320 --> 00:23:23.419 yeah bunch of them actually yeah oh good good good good how do I open it without 00:23:19.980 --> 00:23:23.419 damaging the fancy 00:23:24.919 --> 00:23:34.580 yeah but it's so complicated if I open it like that we are gonna damage it 00:23:30.480 --> 00:23:37.799 and like people will say ah 00:23:34.580 --> 00:23:39.480 no it's just like the plastic yeah it's 00:23:37.799 --> 00:23:46.140 just discoloring from being stretched okay let me cut maybe more section 00:23:43.260 --> 00:23:48.380 without cutting myself maybe wait that's it 00:23:50.159 --> 00:23:58.320 it's just molded silicone it's pretty on 00:23:54.419 --> 00:24:00.000 your hand I guess what I mean uh what is 00:23:58.320 --> 00:24:04.260 it conductive maybe maybe we can use your multimeter to see if there is any 00:24:01.740 --> 00:24:07.799 conductivity inside of it at all or on the surface or whatever sure uh yeah why 00:24:06.720 --> 00:24:11.880 don't we do that first then and then we'll open this one up after okay so 00:24:09.780 --> 00:24:16.100 show me how we how do we test that say between the here and there is there 00:24:14.460 --> 00:24:21.179 any conductivity overload nothing oh okay so basically 00:24:19.320 --> 00:24:24.120 the resistance is very high then what if I get very close 00:24:22.440 --> 00:24:27.600 no there's nothing well I mean this thing is probably goes to gigahomes and 00:24:26.039 --> 00:24:31.799 it's not seeing anything and nothing inside too it does go to Giga one giga 00:24:31.020 --> 00:24:37.380 ohm yeah so this this is just glitter 00:24:34.679 --> 00:24:42.120 embedded in silicone then oh this is the package germanium titanium 00:24:40.919 --> 00:24:47.880 oh what shower okay it's okay for shop it's 00:24:45.480 --> 00:24:52.679 oh you can wear it in the bathroom well when taking a shower this guy has it 00:24:50.520 --> 00:24:56.400 around his neck we we have to connect the handle of this thing to one side and 00:24:54.780 --> 00:25:01.620 the top of this thing to the other side and see if it jumps between the whole 00:24:58.440 --> 00:25:04.440 thing or not oh I see we just need a 00:25:01.620 --> 00:25:09.120 piece of wire I guess I have some stuff okay so theoretically what happens when 00:25:07.200 --> 00:25:14.700 I press the button now well if those glitter are conductive it might jump you 00:25:12.360 --> 00:25:18.659 might see an arc or something I can see anything it's going but it's 00:25:17.039 --> 00:25:24.380 not arcing maybe you can get closer and closer at 00:25:21.480 --> 00:25:29.340 some point it may jump I think it's just jumping directly going 00:25:26.700 --> 00:25:36.120 through the air that Glitter is not titanium germanium 00:25:32.640 --> 00:25:38.159 worse than air basically it's worse than 00:25:36.120 --> 00:25:43.320 air it doesn't even bother going through the Restland yet it's worth noting in 00:25:40.559 --> 00:25:48.240 all of the discussion of BS Wireless ESD wristbands that even wired ones are not 00:25:46.140 --> 00:25:52.200 necessarily within spec this one for example is not to spec not because you 00:25:50.760 --> 00:25:56.880 won't be able to dissipate any electrostatic buildup on your body but 00:25:54.600 --> 00:26:00.539 because it is conductive inside to out meaning that in the event you were to 00:25:58.440 --> 00:26:03.419 accidentally rest your wrist against something that had a current flowing 00:26:01.860 --> 00:26:09.779 through it you could easily cause a short and yeah I mean I I just wanted to 00:26:07.320 --> 00:26:13.679 say that that's true because even with my wedding ring I accidentally touched 00:26:11.640 --> 00:26:18.840 some power lines and blew up some stuff so you definitely don't want that around 00:26:15.720 --> 00:26:21.179 you now let's take a look at the Bro the 00:26:18.840 --> 00:26:26.340 Bro may actually be the less snake oil of the two and there is a resistor 00:26:23.159 --> 00:26:28.320 connected on one side to I suppose the 00:26:26.340 --> 00:26:33.620 metal underneath and on the other side it's just floating no it is not 00:26:30.360 --> 00:26:33.620 connected to the metal underneath 00:26:34.200 --> 00:26:40.919 for God segment what was that they just 00:26:37.919 --> 00:26:43.500 oh my God pour some Electronics sprinkle 00:26:40.919 --> 00:26:48.659 it in a box and say it's electrostatic discharge protector garbage oh my God 00:26:46.620 --> 00:26:54.480 it's not it's not even adhesive-backed it is just wait oh you know what no the 00:26:52.080 --> 00:27:00.000 screw must be connected to that side oh yeah and then there's a resistor and 00:26:57.299 --> 00:27:04.620 then it just goes to a little bit a little piece of rubber what's the value 00:27:01.679 --> 00:27:09.659 of this resistor though you can see my old eyes yeah I can take a picture there 00:27:06.539 --> 00:27:12.840 you go there's a brown black and green 00:27:09.659 --> 00:27:14.400 means one Mega ohm oh okay yeah you can 00:27:12.840 --> 00:27:17.580 probably check it with your meter oh yeah let's do that I mean for all we 00:27:15.960 --> 00:27:21.000 know this could be not even a real resistor maybe they burned it first and 00:27:19.620 --> 00:27:28.440 then put it in there yeah it could be defective resistor or it's a magic resistor the value doesn't matter 00:27:24.539 --> 00:27:30.059 yeah yeah I mean not as tight tolerances 00:27:28.440 --> 00:27:35.039 that oh actions that is yeah that's pretty good it's nice okay so I guess 00:27:33.299 --> 00:27:41.400 with the person of this wristband what do you get a one Mega Ohm resistor 00:27:37.440 --> 00:27:43.320 a box you can hold your mega resistors 00:27:41.400 --> 00:27:48.120 in good components yeah yeah and it's so 00:27:45.840 --> 00:27:51.659 convenient because you can you can wear all the all the resistors that you need 00:27:50.039 --> 00:27:57.419 and they're just they're right there you just open it and soldering 00:27:54.179 --> 00:27:59.640 yeah it's it's convenient uh holder for 00:27:57.419 --> 00:28:04.559 your res components yeah and this is a convenient segue to our sponsor eight 00:28:02.220 --> 00:28:08.279 sleep trust me when I say sleep is important you don't want to be like this 00:28:06.659 --> 00:28:13.020 guy waking up in the middle of the night so try out eight sleep temperature is 00:28:11.340 --> 00:28:16.620 one of the most important factors in improving your sleep and eight sleeps 00:28:15.059 --> 00:28:21.299 products allow you to control the temperature on both sides of the bed 00:28:18.480 --> 00:28:25.320 independently it's adjustable from 55 degrees Fahrenheit to 110 degrees 00:28:23.159 --> 00:28:29.279 Fahrenheit which is perfect for partners with different preferred temperatures 00:28:26.880 --> 00:28:33.360 like me and my wife all of their features such as temperature control 00:28:31.020 --> 00:28:37.440 vibration alarm and sleep pattern insights are easily accessible through 00:28:35.460 --> 00:28:41.400 their Simple app I've personally been using the Pod cover and now you can get 00:28:39.179 --> 00:28:45.779 one too head over to the link below and check out eight sleep and use code LMG 00:28:43.860 --> 00:28:51.480 for a nice discount on the Pod cover because sleeping better is living better 00:28:49.140 --> 00:28:55.799 if you guys enjoyed this video the obvious one to go check out is the last 00:28:54.120 --> 00:29:00.000 time we collab there's actually two videos there's one on our Channel 00:28:57.659 --> 00:29:03.539 there's one on electrobooms channel both of them are awesome two kind of 00:29:01.919 --> 00:29:09.720 different perspectives on the The Challenge which was our attempt to kill 00:29:06.480 --> 00:29:12.120 components with an ESD discharge gun now 00:29:09.720 --> 00:29:17.400 how did that gun compare to this thing well that one was regulated 00:29:14.700 --> 00:29:21.659 to be the least this is not I mean if your device survives this then you are 00:29:19.980 --> 00:29:23.840 passing everything with flying colors okay
