I wish youtube existed when I was a kid. I'd have likely figured out what I actually wanted to be when I grew up.

Had no idea I liked that stuff. Especially not 30 years ago, at 12 yrs old.

I ended up becoming an automotive tech at 30 yrs old once I finally realized I loved working on cars and I finally didn't GAF if people knew I went to a vocational school. Why? Because In the 90s, it was beat into our brains that you had to go to a 4 yr college to be successful in life. Yea that didn't work either lol
Couple of things: I really recommend getting the Fluke voltage detector. Other brands have failed to indicate on me. The Fluke is fantastic and trustworthy. Second, in the US the Harbor Freight "Circuit Breaker Detective" is actually quite good and is $25. You plug one into the outlet then the other you sweep across the breaker box and it tells you which breaker is attached to that outlet. I used it to map all the circuits in my house when I was preparing to install solar, so I could characterize all the circuits and get an even load between phases and decide what to put on the backup panel.
I thought of getting that harbor freight one as well, but I like the added features in the transmitter. Like GFI testing, wiring indicator lights. Plus for only about $5 from the basic Klein price, you can get the kit with the jumper leads, 2-pole and Edison adapter for testing by other methods.
Fluke's great if you do this sort of thing for a living, but for the home gamer Klein is about in the right ballpark. It's not garbage, but doesn't cost you a weeks' wages either. I do the software side of industrial automation. My technicians own Flukes. My tool bag has a mix of Klein (for when it matters) and Harbor Freight (for when it doesn't).
@@jeffspaulding9834 The Fluke detector is $27. I hope that's not a week's wages for you. For a dollar or three difference I just buy the Fluke. Klein is fine. I got bit by a Sperry - it's a garbage brand sold at home improvement stores and I just needed one fast so bought one - mistake.
I live in an apartment with questionable wiring in Europe. I was replacing an outlet that had two wires connected to it. One came from inside the wall, the other one was mounted on the wall in a small cable conduit. I assumed that the wire inside the wall was connected to the breaker box and the other one to clearly retrofittet outlets in the room. I turned off one (of 5) breakers and measured 0V on the wire inside the wall. I felt safe, but luckily decided to short live and neutral just to make sure. Nothing happened on the wall cable but I almost shat myself when I heard the loud bang and saw bright flash when I shorted the other one. It was a lot louder than I expected.
hi mehdi im sure you won't see this with the boatloads of comments you get on your videos, but thanks to you and your projects and lessons you've reignited my love for science and i've decided to go back to school for my GED. i think im gonna try to become an engineer :) so thank you for your inspiration and your help
I started to love electronics as a kid by taking a DC motor from an RC car and connecting its two wires to a AA battery. It worked, and from then on, I began studying electronics. I got really good at it by watching your videos. Initially, I watched them just for laughs, but once I realized how educational they were, I started watching ElectroBOOM. I began studying electronics in school around grade 3 or 4, but after grade 10, I took commerce, and my focus on electronics ended. However, I will never forget you and my love for electronics. Now, I have no idea what to do with the multimeter, soldering iron, and the circuits I made.😅
5:38 In Europe we have those coils, because it will make faster switching off high currents like at short circuit (In typical B its 3-5 times nominal current and C is 5-10). Its much much safer in that way, because whole time at short circuit all ground wires (PE) has dangerous voltage until breaker will switch off. Of course if somebody doesn't care, then impedance (resistance) of wires and connections in installation can be too high to make it work fast enough. Same with many and long extension cords.
Building companies are obligated to use the most cheap and thiny wires in installations. But i can see something interesting: in the near past regular main brakers here was rated for 63A. In nowadays 40A is a norm. When everything you think about is electrical.
@@mamatidea Where is that? Single phase? In Hungary we can get 3x32A (3 phase) service for houses. Anything above 32 A per phase requires a lot of work and is rare for residential applications.
I am actually feeling proud of myself for understanding all that he mentions in the video. But I can hardly imagine that without Mehdi's explaining methods. Thank you so much, man 🙏
I’m an electrician and I built myself a switch box that goes through some high grade extension cord into a male plug end. I plug it in and flip the switch and the breaker pops. Sometimes when the breaker is bad or made by stab-lok the wire tenses up in my hand and makes a buzzing sound before the breaker trips. The magnetic forces generated during short circuit conditions are insane.
Like he said in the beginning, you can inadvertently trip the main breaker or device further upsteam by doing it like you said. I suppose yours can be used in a restricted residential environnement, but still not the best, greetings from a fellow electrician... It shows he's a engineer of the practical type 😂
@@mickeygallo6586 I haven’t tripped any breakers upstream yet but I’ve mostly used the “plug shorter 9000” in residential settings. In the few commercial buildings I’ve used it I’ve never had trouble with it. If all the breakers are in good condition the 15-20A breaker for the plug circuit should trip several cycles before the 40-200A breaker feeding the branch circuit. In my experience the breakers or fuses upstream are feeding 240v while all the branch circuits are 120v so they don’t all trip at once. I have blown main fuses before when I accidentally shorted the 240v on a split plug. I think that a phase to neutral short is significantly less aggressive than a phase to phase short. Anyway, I am well aware of the risk of tripping feeder breakers/fuses when I use the “plug shorter 9000” so it isn’t my first choice to use. Typically I use it in houses where they have 4+ sub-panels and they are spread all around the house, so I just pop the breaker and look for the tripped one later. I’ve actually found bad connections in a panel before using the plug shorter 9000.
I've seen an electrician use a similar box as you describe, but their switch was another circuit breaker. Guess they used a type with higher current rating or slower response than you would usually have in a residential installation. This way, if for some reason the circuit breaker in the building failed to trip, the one in the electrician's box would trip before there could be a fire.
@@andreasu.3546 that would be safer than what I use. I built mine out of left over parts from a job and stock material from my van. I just use a normal 15A toggle switch in a metal box with a metal cover. If the breaker fails to trip the contacts in the switch should burn out long before the wire or the plug in the wall socket. Since everything is in a metal box it should prevent any fires or injuries in the unlikely event of catastrophic failure.
I've used these circuit finders so much and never really understood how they worked. I always falsely assumed they were putting a high frequency signal on the line somehow (I come from the telephony / IT industry and use Fluke tone gens a lot). I always wondered how you could pinpoint the "signal" on a single breaker and how it wouldn't just spread to the other breakers. Then it clicked, and you said it at the end, it only travels on the circuit where it is pulling current because the signal itself is current! So amazing!
electrician here as well, the yellow tool had a special end so you could stick it into a north american outlet to see if the outlet not only has power but that the hot wire is on the correct side of the outlet, lol keep up the funny stuff. ive subscribed for a long time and alway like your videos. when do i get one of those ocissiscopes you keep blowing up?
Thank you for making these videos. Im just now going to school for an electrical technician and i lernt a lot of stuff from you and my dad who is an electrician.
The breaker finder is one of my most used tools. Especially in older buildings. They are prone to errors due to noise, but even when you do get an induced signal it's easy to figure out. Everyone should have one. Definitely any homeowner.
I have a different method for mapping circuit breakers in a house. 1. Give every circuit breaker in your house a binary number. Make sure not to use all zeroes and all ones. Example: you might label your breakers from 1 (0001) to 14 (1110) 2. Look at the first digit of the number and turn the breakers on and off depending on that digit. 3. Check all outlets to see which are dead and alive, and record which it is as the first digit corresponding to that outlet. 4. Repeat for every digit. When done, every outlet will have a number based on the breakers number. If any outlet has the number 0000 it's always off and 1111 is always on (which is why you should not assign these numbers.) This is great to systematically map out every breaker in a new house. But maybe not so great to find a specific breaker for a specific outlet (Yes I work with computers)
I just turned off my breakers one at a time and checked which devices and outlets stopped working (checked the outlets with a phone charger). It's a bit of a slow process, but it gets faster as you eliminate more and more outlets, and you only have to do it once if you write everything down and don't remodel that often. Such tools are probably meant for maintenance on large buildings (especially ones with rented spaces). It's a cool device, though. I'm glad to know how it works now :)
If you have a lot of breakers, you can do a binary search. You turn off half the breakers to check which half yours is in. Then you flip half of those and so on.
I mean, VFX are appreciated, but not when they cost $22'000+! Also I think they should have some sort of TVS or a fuse on the function generator output.
@@danek_hrenI came up with this comment from when I brought a broken guitar cable up to my grandpa, and he looks and says, “I see, and YOU BROKE IT!” 😂
@@andysjamsessions2598 lol. Yet I still think that's too much to pay (22'000 $ is the price for a keysight scope, the MINIMAL price!) for video effects.
@@danek_hren I understand. 😊 But, yeah, the story about the guitar cable is I was standing up while practicing the guitar. So, I had the strap on the guitar, right? Well, I let go of the guitar and the strap slipped off the guitar. And the guitar fell before I could catch it, but the guitar cable was still plugged into the guitar. And the guitar landed on the ground with the guitar cable still plugged into it. Just, BANG! So I pick the guitar up, and I pull the cable out of it, and the cable is bent at a 45 degree angle. I don’t know how it happened. So, I take it to my grandpa and…you know the rest. 🤣
My father got me one of these devices for Christmas shortly after I bought a home. It's been super helpful! I keep it by my subpanel. Although I'm making it obsolete as I replace switches and outlets by labeling each outlet with the exact breaker number that shuts it off. Since I'm using those two part "screwless" wall-plates, it's really easy to hide the label, but find it when I need it. Anyway, I highly recommend these for anyone doing electrical work.
@@Avalanchanime He's joking about getting shocked so often in his videos. His body is the resistor so when he touches live and earth at the same time, it completes a circuit
I recently did a HUGE site that needed ALL breakers found. Old factory Absolute nightmare. Tried everything you used. Keep in mind Europe here. 3 fase, even tho thinking it is single fase (as I said nightmare (it looked like a socket and was used as one, so it "dragged" its voltage once "off")). Even the earthing was not 0. Thats how bad it was. Yes, some of this stuff helps. And in minor cases it is perfect. I had worse case. For house stuff, perfect. Industrial, old. Oof. I noticed that the tools you showed have a real bad time when the earthing isnt up to date.
I picked up that same Klein unit recently, much easier to find the right breaker with it than the oldschool analog one I had before. Not at all what I was expecting the injected signal to look like, I figured it was just a low-ampltude high frequency signal riding on the line wave like the old ones, just with a more sophisticated receiver.
13:20 - he doesn't explain why the current spike is only every 7th cycle. There didn't seem to be a microcontroller in the plug device to do any switching.
@@mb-3faze Referring to the circuit at 13:13, after the SIDAC has fired the capacitor is fully charged and there's no voltage across the SIDAC. The capacitor then discharges over several cycles via the resistor and the voltage across the SIDAC rises. When it reaches 120V the SIDAC fires again.
I actually just had an electrician come over to install a vent fan in our bathroom earlier this week and he seemed to be slightly impressed by my very basic knowledge of electrical stuff. Thanks Mehdi.
@@monad_tcpi think the fuse popped, like what maniac made expensive equipment without some sort of fuse so you don't need to buy a new one when it broke by accident
At work, I was working on a 32A radial circuit and accidentally shorted live to earth with a screwdriver when attempting to re-tighten the live terminal of a socket... Completely blew up the end of my terminal screwdriver. For context, I was removing a bunch of old sockets but I couldn't find the breaker. The board was (annoyingly) completely unlabeled so I had no clue which breaker it was and I was unable to start switching random things off due to the systems that the board was powering. I opened up the last socket in the radial to determine what the cables were like so I could maybe trace them back to the specific breaker, but I noticed that the screw on the live terminal of the socket was sticking out a bit and slightly loose, so I took my screwdriver and went to tighten it... even though it was insulated, the uninsulated end just happened to touch the metal body of the socket at the same time as I touched the live. There was a massive bang, a big spark and I was left with a big chunk taken out of the driver. But hey, I found the breaker!
@@yeeterooni7352No, MCB has a type that shows how much current can go throught the line before circuit will be broken. So if its class C (for inductance stress) max amps wil be N*10, so for 32A MCB it will be 320A, but for 5A MCB it will be 50A. Do you see it? Sparks will be different.
@@yeeterooni7352 Lower current breakers will turn off slightly faster, but usually not enough to matter much when it comes to sparking potential, true. But the higher current the circuit, the larger diameter the wires feeding it, which significantly reduces impedance and by that does ramp up the destructive potential in a dead short situation quite a bit.
Ooh, is this on a British "far safer, far better" socket?? Those ones that don't have breakers, because instead it's better to put fuses in every plug?? Color me shocked!
As an automotive technician with a pretty decent automotive electrical skill bro has already dropped 3 terms on me I’ve never even heard of. This man is insanely smart. We don’t deal with nearly what he knows and our stuff is still fairly complicated in my opinion.
Very cool! At work I just do low voltage so we use normal toners that I sometimes hear in my nightmares, especially after troubleshooting speakers. Putting a toner on a 70v speaker line will cause them to play the tone so I occasionally spend an entire day listening to the beeping
They use network cable tracers with a special adaptor jerry-rigged together to trace wires in walls. Works like a charm! Just adapt the rj45 port to 2 crocodile clips and connect it to live and neutral (obviously disconnecting the breaker first)
Mehdi I like doing the kind of stuff you do(not the really high voltages) but you’re the one who has taught me some stuff about circuits and that stuff. My dream job is an electrical engineer I decided this before I came across your channel and your videos are funny. Keep up the great work!
These videos have gotten so much more interesting since iv started studying electrical engineering. I can actually understand along with just enjoying the pure chaos lol
Its usually called a surge protector (so things like lightning don't fry your electronics connected to your power bar when your power goes out) and honestly i find its harder to find ones without them nowadays. some have a switch on/off, some have a reset button, and some are 1 time use and completely internal. good stuff to keep your devices protected in the event you get a huge current rush at the outlet side like from lightning or someone running their car into a power pole outside your house if you can imagine.
I didn't even know till I watched this video that there is a tone and probe for electricity lines. Up till now I only used the tone and probe for networking cables. Thanks
Wow.. this is like an ElectroBOOM and a Big Clive video all in one! And it was actually really informative, too. I'd always had my assumptions about how these devices did what they did, but never bothered to actually open one up and find out. I actually wouldn't have thought of just using a capacitor with a DIAC... (FWIW, a SIDAC is arguably just a particular type of DIAC. To be honest, I don't really even understand why people gave it its own acronym. It's really just a "Five-layer-construction Silicon DIAC")
I know this was gold. I was NOT disappointed. And Klein tools are all insulated. Sure I have a breaker finder but it's so much easier to just use my insulated screwdriver and BAM found
Why not just flip the breaker off and see which outlets stop working? Seems like a pain to mess around with signal injectors and intentionally overloading circuits if you don't have to.
In a business or office as well as industrial buildings or such environments in which huge machines or servers have to run with multiple breakers without context on a same place we can't turn one off in hopes to find the one we were looking for just to know we shut down the server or blew some heavy machines up.

When done, every outlet will have a number based on the breakers number. If any outlet has the number 0000 it's always off and 1111 is always on (which is why you should not assign these numbers.)
This is great to systematically map out every breaker in a new house. But maybe not so great to find a specific breaker for a specific outlet
(Yes I work with computers)
I just turned off my breakers one at a time and checked which devices and outlets stopped working (checked the outlets with a phone charger). It's a bit of a slow process, but it gets faster as you eliminate more and more outlets, and you only have to do it once if you write everything down and don't remodel that often. Such tools are probably meant for maintenance on large buildings (especially ones with rented spaces).
It's a cool device, though. I'm glad to know how it works now :)
Even faster if you plug some lights into sockets in every room, then you can just tally up which ones are on
If you have a lot of breakers, you can do a binary search. You turn off half the breakers to check which half yours is in. Then you flip half of those and so on.
2:35 - impressive simulation of smoking the Keysight o-scope.
... it was a simulation, right?!?
Mehdi you should come to Serbia, our outlets are waiting to be tested
Also to finland right man
Don’t encourage him to
He might need a UN peacekeeper to accompany him 😂
@@Sniperboy5551 you might need a psychiatrist to accompany yourself
If you have a country-wide power outage in the next few weeks, you will know why.
2:30 I see, and YOU BROKE IT!
its Keysight they thought of this replacing a safety fuse will bring it back to life :)
I mean, VFX are appreciated, but not when they cost $22'000+!
Also I think they should have some sort of TVS or a fuse on the function generator output.
@@danek_hrenI came up with this comment from when I brought a broken guitar cable up to my grandpa, and he looks and says, “I see, and YOU BROKE IT!” 😂
@@andysjamsessions2598 lol. Yet I still think that's too much to pay (22'000 $ is the price for a keysight scope, the MINIMAL price!) for video effects.
@@danek_hren I understand. 😊 But, yeah, the story about the guitar cable is I was standing up while practicing the guitar. So, I had the strap on the guitar, right? Well, I let go of the guitar and the strap slipped off the guitar. And the guitar fell before I could catch it, but the guitar cable was still plugged into the guitar. And the guitar landed on the ground with the guitar cable still plugged into it. Just, BANG! So I pick the guitar up, and I pull the cable out of it, and the cable is bent at a 45 degree angle. I don’t know how it happened. So, I take it to my grandpa and…you know the rest. 🤣
Every time Mehdi is about to blow something, that instinct of saying "Don't do it" kicks in every time 😂
😂
Same here😬
Thank you for sharing our passion for Electrical Engineering and electronics in such a fun way.
I always get excited when I see a new upload!
My father got me one of these devices for Christmas shortly after I bought a home. It's been super helpful! I keep it by my subpanel. Although I'm making it obsolete as I replace switches and outlets by labeling each outlet with the exact breaker number that shuts it off. Since I'm using those two part "screwless" wall-plates, it's really easy to hide the label, but find it when I need it. Anyway, I highly recommend these for anyone doing electrical work.
I always wondered how those breaker finders worked! Thank you sir! You are an excellent teacher, I really enjoy your content Medhi!
Awesome vid! More electronics concepts than usual!
Also the joke "the resistor falls between live and earth like I always do" was so casual but I caught it haha
Happened upon this comment AS he said it lol.
May I ask you to explain me what does it mean? 🙏
English it is not my mother language
@@Avalanchanime He's joking about getting shocked so often in his videos. His body is the resistor so when he touches live and earth at the same time, it completes a circuit
rip keysight. Great video, thanks ElectroBOOM!
I know he is sponsored and gets free scopes, but that smoke puff hurt my soul.
Yes rip keysight
why did it blow up? 120v AC should be no problem for that scope.
@SomeGuysGarage I mean you basically shorting ac to DC power of oscilloscope with no power limit
The diference of hz made it blow maybe
I recently did a HUGE site that needed ALL breakers found. Old factory Absolute nightmare. Tried everything you used. Keep in mind Europe here. 3 fase, even tho thinking it is single fase (as I said nightmare (it looked like a socket and was used as one, so it "dragged" its voltage once "off")). Even the earthing was not 0. Thats how bad it was. Yes, some of this stuff helps. And in minor cases it is perfect. I had worse case. For house stuff, perfect. Industrial, old. Oof. I noticed that the tools you showed have a real bad time when the earthing isnt up to date.
I picked up that same Klein unit recently, much easier to find the right breaker with it than the oldschool analog one I had before. Not at all what I was expecting the injected signal to look like, I figured it was just a low-ampltude high frequency signal riding on the line wave like the old ones, just with a more sophisticated receiver.
13:20 - he doesn't explain why the current spike is only every 7th cycle. There didn't seem to be a microcontroller in the plug device to do any switching.
@@mb-3faze Referring to the circuit at 13:13, after the SIDAC has fired the capacitor is fully charged and there's no voltage across the SIDAC. The capacitor then discharges over several cycles via the resistor and the voltage across the SIDAC rises. When it reaches 120V the SIDAC fires again.
That burn mark at 2:00 😂
6:10 Mehdi the AC generator 😂
😂
For anyone searching there is full version "3-Phase Dream" on his second channel (Mehditation)
I love that you still have sponsors
I love how Mehdi keeps us entertained while also learning
6:11 No wayyy
What is Medhi doing?
@@tankers4all 3-Phase Dream baby. Pure mehditation.
3:18 - amazing cartoon artistry, i loved it 🤣🤣🤣🤣
I actually just had an electrician come over to install a vent fan in our bathroom earlier this week and he seemed to be slightly impressed by my very basic knowledge of electrical stuff. Thanks Mehdi.
This is the best science teacher ever.
2:30 The exact moment when Mehdi himself realized he had gone too far 😂😂
rip signal generator
@@monad_tcpi think the fuse popped, like what maniac made expensive equipment without some sort of fuse so you don't need to buy a new one when it broke by accident
Rip oscilloscope
Yep lol.
I dont understand most of this but I couldn’t stop watching. So entertaining! Great work thank you.
At work, I was working on a 32A radial circuit and accidentally shorted live to earth with a screwdriver when attempting to re-tighten the live terminal of a socket... Completely blew up the end of my terminal screwdriver.
For context, I was removing a bunch of old sockets but I couldn't find the breaker. The board was (annoyingly) completely unlabeled so I had no clue which breaker it was and I was unable to start switching random things off due to the systems that the board was powering.
I opened up the last socket in the radial to determine what the cables were like so I could maybe trace them back to the specific breaker, but I noticed that the screw on the live terminal of the socket was sticking out a bit and slightly loose, so I took my screwdriver and went to tighten it... even though it was insulated, the uninsulated end just happened to touch the metal body of the socket at the same time as I touched the live. There was a massive bang, a big spark and I was left with a big chunk taken out of the driver. But hey, I found the breaker!
Doesn't matter if your circuit is 15A or 50A. It will result in the same arc and short circuit.
@@yeeterooni7352No, MCB has a type that shows how much current can go throught the line before circuit will be broken. So if its class C (for inductance stress) max amps wil be N*10, so for 32A MCB it will be 320A, but for 5A MCB it will be 50A.
Do you see it?
Sparks will be different.
@@yeeterooni7352 a 15 A circuit breaker will trip faster.
@@yeeterooni7352 Lower current breakers will turn off slightly faster, but usually not enough to matter much when it comes to sparking potential, true.
But the higher current the circuit, the larger diameter the wires feeding it, which significantly reduces impedance and by that does ramp up the destructive potential in a dead short situation quite a bit.
Ooh, is this on a British "far safer, far better" socket?? Those ones that don't have breakers, because instead it's better to put fuses in every plug?? Color me shocked!
I love your creativity with editing
2:30 welp sponser by Keysight going back to sleep
I love your content man. It's educational when I'm sober and entertaining when I'm high.
4:46 I don't think "Sexas Instruments" is ever going to get old for me. Hilarious!
Damn, that state is hot...
I use those breaker finders occasionally and they're super helpful. It was really cool seeing how they work!!!

I hear "go&try this at home" 😂
just kidding ... love your content ❤
As in some earlier video: "dumb kids - stop watching now. Smart kids - don't do it at home".
Never.

i hear "don't try in my home", which i don't
Man I absolutely love this guy, grew up watching him and he has always made me laugh no matter how my day have been
Hi mehdi! Big fan here from india, keep educating peoples along with the entertainment. 🤝
man you always brighten up my day , thanks for kepping the depression away man ... live long 😇
Hi electroboom, I like the way you play with electrons!🎉
As an automotive technician with a pretty decent automotive electrical skill bro has already dropped 3 terms on me I’ve never even heard of. This man is insanely smart. We don’t deal with nearly what he knows and our stuff is still fairly complicated in my opinion.
This guy is the only guy on TH-cam posting interesting, legit content. No clickbait and BS
Very cool! At work I just do low voltage so we use normal toners that I sometimes hear in my nightmares, especially after troubleshooting speakers. Putting a toner on a 70v speaker line will cause them to play the tone so I occasionally spend an entire day listening to the beeping
7:52 ......MEH you!....
Lmao, seller's eyes when he says that
They use network cable tracers with a special adaptor jerry-rigged together to trace wires in walls. Works like a charm! Just adapt the rj45 port to 2 crocodile clips and connect it to live and neutral (obviously disconnecting the breaker first)
You said that you will buy and try the 5g bioshield if the plasma vortex video gets 100 000 likes and it did!
@mrwhosetheboss made a good video about this scam if you're interested🤝🏻
Mehdi I like doing the kind of stuff you do(not the really high voltages) but you’re the one who has taught me some stuff about circuits and that stuff. My dream job is an electrical engineer I decided this before I came across your channel and your videos are funny. Keep up the great work!
Great content!
bigclive mentioned!!! hell yeah!
Uh, anybody else worried about those burn marks under the desk, above that power strip, at 2:00 ?
At this point you should be worried about his wife and daughter instead of black marks under table 😂😂😂
It's fiiiiiiiiiiiine he's a professional!
No why worry. Get a grip
These videos have gotten so much more interesting since iv started studying electrical engineering. I can actually understand along with just enjoying the pure chaos lol
9:19 "nervous sniff"
made me spit out in a burst of laughter lol
Stroking the nose hair, preparing for the smell of burning plastic and ozone 😂
Fox and Hound, have been using one for years. Great device. Thanks for explaining it in more detail.
0:45 thats an oddly specific possible outcome 🌝
the shopping animations were my favorite parts. the technical stuff, very well presented, yet again. thanks Mehdi!
0:33 no power
The quality of Mehdi's videos is something else
2:01 this is my first time i see a power bar with breaker
Its usually called a surge protector (so things like lightning don't fry your electronics connected to your power bar when your power goes out) and honestly i find its harder to find ones without them nowadays. some have a switch on/off, some have a reset button, and some are 1 time use and completely internal. good stuff to keep your devices protected in the event you get a huge current rush at the outlet side like from lightning or someone running their car into a power pole outside your house if you can imagine.
@@FaTALiNFeRN0 thanks
I didn't even know till I watched this video that there is a tone and probe for electricity lines. Up till now I only used the tone and probe for networking cables. Thanks
Just make sure not to hook your networking tone generator onto live wires, it works differently and might blow up
Mehdi is definitely gotten better with his editing
you’re great!!! love your interactions with the products you deal with and your insights are fantastic!! please keep uploading your great videos!! 👍🏼🥰
Oh perfect, I need to find circuit breakers in my apartment!!
I will follow this tutorial step by step!
3 explosions later... step 7 is "go out and buy the right tool" :D But at least you know how it works.
This was a fantastic video on electrical analysis, thank you!
@10:48 "LA BOOM!" 😂
2:29 there goes an expensive scope by sending live voltage back down the function generator
3:19 I love shopping at STUFF SOLD HERE
I love your videos. Both instructive and humorous.
Me when I see a new ElectroBOOM video in my notifications: 10:59
Wow.. this is like an ElectroBOOM and a Big Clive video all in one!
And it was actually really informative, too. I'd always had my assumptions about how these devices did what they did, but never bothered to actually open one up and find out. I actually wouldn't have thought of just using a capacitor with a DIAC...
(FWIW, a SIDAC is arguably just a particular type of DIAC. To be honest, I don't really even understand why people gave it its own acronym. It's really just a "Five-layer-construction Silicon DIAC")
2:24 i think you broke it
2:30
It's broke 😂
The resonant sensor explanation was brilliant! I was in owe the entire time :0
Your animations, dude... LOL 😂
Now you're getting into stuff I do often enough at work. I thought I had all the sensors. The one that finds the breaker is new to me. Pretty cool
Thanks for the video,
Can you make an emp
he already did a video on that
i like the fact that he trys to make us learn and laugh
2:27 - please tell me it was just an off-screen capacitor and you didn't kill that expensive scope for that joke 🥺
He knows what he does. So ofcourse not
most certainly
I would like to know how you commented hours ago when his video just came out.
How is this comment posted 8 hours ago?
The video literally came out like a minute ago??😂
How is this comment 8 hours old. The video is only 5 minutes old
How?
I know this was gold. I was NOT disappointed. And Klein tools are all insulated. Sure I have a breaker finder but it's so much easier to just use my insulated screwdriver and BAM found
Why not just flip the breaker off and see which outlets stop working? Seems like a pain to mess around with signal injectors and intentionally overloading circuits if you don't have to.
In a business or office as well as industrial buildings or such environments in which huge machines or servers have to run with multiple breakers without context on a same place we can't turn one off in hopes to find the one we were looking for just to know we shut down the server or blew some heavy machines up.
You are the most awesome science teacher I wish I could have
4:18 half life alyx
I have that same sensing pen. It does have multiple sensitivities. Theres a button press sequence you can do to change the sensitivity.
