I would personally use my hairdryer's heating element as a seat warmer like you first did it in your seat warmer video
I waited for a few years for him to light his ass on fire. It did not disappoint :)
Dont forget the hot glue
its a very safe and useful DIY. I agree with this choice
@@canonip3000 ah lots of poisonous gasses
Man your Bam bam will Love the fire 🔥
I love the fact that when Medhi high fives his daughter, it makes the same sound as a fuse popping. Which in turn causes him to react with the same scream he would make if a fuse had blown. Either coincidence or an Easter egg, I love it.

@@thegrumpydino67nobody cares
As an industrial electrician i love the way that im still entertained by your antics even though I can see whats about to happen.
If these vids were around 25 years ago i would have been doing all this in my teens.
Great content
Hahaha that's the magic in it, I know he is going to get shocked but it still makes me laugh so much.
(9:38) this spoon potentiometer is one of the best physics demonstrations ever!! You can see the wire getting hotter when there's less resistance, and you can conclude that more current flows through
@koiun dwrru He's actually such a genius, making a hairdryer from scratch so that the viewers get an "aha!" moment, like I had.
sure ohms law does work here but for a given temperature. A wire of a given length will have a specific resistance and this resistance is a function of temperature so a thermal runaway will result in resistance runaway till the wire breaks.
@@ulrichraymond8372 the less resistance by heating is not that much to make it run away.
@@TheFearedTurtle das a bot
That foam cutter looks insanely useful, the "official" ones are usually pretty expensive.
Also, "insanely useful" seems like a bit of a stretch, lol. I can't think of a single time I ever needed to cut squiggly lines into a piece of foam
@@PimpedKoalas you use it to sculpt foam for all kinds of things. Not just for drawing squiggly lines in things.
@@PimpedKoalas >not useful for you >not useful for anyone else. that's how the world works right?
@chuggs I mean if you can burn your house down with 2 AA batteries you probably shouldn't touch anything that's using electricity
Steel wool and a 9v is often used as a firestarter btw
If you watch his videos from the perspective that everything that happens is intentional, (which I'm pretty sure is the case) you'll realize that Mehdi is a legitimate genius. Seriously.
Of course he's a genius, he gets everything he wants to work the way he wants
@@sayori3939 if he wants to explode he will explode
Everything that happens is as planned its not plausible for him not to expect anything different that want he shows.
Everything but the Jacobs Ladder falling on him.

@@cheaterman49 yeah I remember that one. Every time there is a large gap between videos I think something bad might have happened.
Props to Mehdi for showing how to do things the wrong way first so that we learn *exactly* what happens when you do it wrong.

This was probably my favorite episode of yours. Inventive and hilarious as always. Keep it up Mehdi!
8:45 Loop-a Doop-a Loop-a Doop-a Loop-a Doop-a Loop
The magnet connecting batteries trick blew my mind completely, I was thinking how to get rid of battery holders for a project some time ago
i think neodymium is much more resistive than copper
it will heat up much more especially in the use case of this video with high current
and hot stuff around rechargeable batteries or just batteries in general isnt a good idea
If you pass current through the casing of those magnets, be aware of the heat that this current would generate, and make sure that the magnets won't reach their Curie temperature, at which they'll lose their magnetic property. Best of luck to you.
not a great idea for a long time, magnets lose their magneticity when exposed to heat over time
@@ozonesama Oh neat, I didn't know about that! So how gradual is the degradation before that point? I guess what I'm asking is if magnets are mostly fine until a certain threshold and only tend to stop working above that point, or if long term low grade heat will decrease the effectiveness a lot too?
@@idontwantahandlethough It depends on the materials involved, I guess? I saw in that video ( czcams.com/video/rOgGJaO5C00/video.html ) that Nickel could rapidly switch back-and-forth between ferromagnetic and non-ferromagnetic, and if you know how MiniDiscs used to record data, it used a laser heat source, so it can be a very quick process, once that material's Curie temperature is reached. If you stay quite bellow that temperature, I don't think that, even by repeated prolonged exposure, you'd loose magnetism.
Can we all take a moment to appreciate the Heated Entertainment electroboom has given us. I love it
It takes a lot of Passion and Skill to make a scripted Video looking this random and improvised!
No. We can't.

Hi Mehdi, the foam cutter you built is a very useful tool, yesterday I tried to build one at home using a car booster that outputs 4 amps of current and I ended up with a blown fuse ahah
However I tried again with a diffent DC power supply and it worked!!!
Keep making videos like these where we can learn a lot of things from broken tools
4:36 A Fire Resistant item, "Wooden Stick" 🤣🤣🤣🤣🤣

I fought wild fire for years....
I once heard a reporter asking another fire fighter a question about the state of the fire. The fire fighter replied: "Well, you see, the thing is... Trees are wood. And wood burns." Then he just turned around and walked away. The look on that ladies face was priceless... So good.

10:36 facial expressions this man is capable are simply astounding
Electrocute is slowly learning from the best already.. "of course, I can make everything"
You too could do this if you electrocuted yourself every day 🤣

I've only stumbled onto your video's two days ago and i've not been able to stop watching. thank you, you have made me want to expand my mind and learn something new. thanks again made my 41st birthday today more interesting
This was a very creative and interesting video based on a simple home product. Great stuff. Thanks!
You forgot to list the mica paper among the interesting parts a broken hair dryer has. The mica can resist temperatures well over 200 °C and is electrically insulating. This combination makes special enough to make noteworthy. If you ever need a structural element in your heater design, mica is a good choice.
It's also really healthy and good to inhale!
@@itzfuazz4198 really?
@@noobkiller9478 i belive that was called irony
@@itzfuazz4198 This is an issue with all refractory materials, so it's a given. From silica based bricks you get silicosis. Famously, asbestos causes asbestosis. Refractory mortar is acidic and burns you lungs and eyes. Ceramic wool is carcinogenic. And so and and so forth. If you're engaged in this kind of hobby, it's good practice to inform yourself of material hazards.
I, for one, think that it'd been safer for Mehdi to make his foam cutter with the mica. What kind of plastic is that clamp made of? Does it gas out formaldehyde when it's getting burned by the hot wire?
You see, it's easy to overdo it with the safety cautions with just about any material. Even water can be toxic, if you drink like 3 gallons of it at once. And people have done it.
@@JoshuaNorton The wire will conduct heat slowly to its outer ends wrapped through the plastic holes but it isn't heated by current farther out than the leads are attached.
But yeah, I'd get a hacksaw frame and come up with some kind of insulator to mount the wire onto it with.
9:08 Mehdi is the type of guy to say “stop it” to a fire
Edit: 1 MORE LIKE!!!
Among other ways of trying to keep it under control, I might add.
Well there is also a guy saying stop it to fireworks/firecrackers
And it stops.
Did it :)
It is gone
You can make a foam cutter with a transformer from a old boom box, a dimmer switch to control temp. And I used kanthal wire for the cutter. I made a top out of some 2x4 and ply wood with and a brace to hold the wires with pvc. Used some other minor parts (screws and such). Works great for making foam forms to do aluminum casting
Always great entertainment when videos come out on this channel love it
Hoo boy, still remember when ElectroCute was just a wee toddler.
We'll be witnessing her growing up at this rate
I'm in shambles, how fucking long have I been subscribed for lol
His electric guitar is still my favourite.
10:47 Ah yes 100 year old children just a normal day on earth.
Thank you! I have a broken hair dryer and wanted to know exactly how much voltage should go to the motor. I'm also thinking about using the nichrome wire to make a soldering iron and maybe a hot wire cutter for foam or even plastic
3:51 Technically, *anything* is a fuse if you try hard enough.
I can use air as a fuse?
Even PC's can be fuse to. Just put you game graphics on the highest setting.
@crazysaturn0805
Or just remove the main power supply and stick straight 110v or 240v on the board. It'll protect your outlet from accidental activation and creates bonus forbidden fog too and fireworks just for fun. Lol
@@crazysaturn0805you mean power resistor?
Perfect cut at 5:46
In high school, I tried making foam cutter without adding resistor.
It turned into lightbulb.
Thanks for commentary, it really helps!
I swear I have never learned and laughed at the same time so much in my life. I love this channel
I love how ElectroBoom always sees a positive side of a failed experiment
He also sees the grounded side
11:38 it sounds like a High Five on High Voltage
Thank you sir for sharing this knowledge

I'm sorry that "Suck Off" joke was so funny I have no idea what exploded at 6:35, rewinding! ❤️

Once you’ve tuned your power for your engraver, you can just make a battery pack with a switch! And if you know you can use different settings with different materials, you could use a pot or microcontroller for variable settings [the MCU option would be better for many variable options or if you wanted power monitoring too]
Electroboom is the best guy in CZcams of talking, building, and surviving of his electric stuffs.
Used to watch him years ago, he never disappointed me. Keep up the great content!

I quite like the idea of a neo-mehdi-um magnet. Can't quite figure out if it would be flame and shock resistant, or prone to exploding though.
This man is a fantastic teacher. Both showing practical elements of electricity as well as demonstrating what can go WRONG in a relatively safe manner.
He knows what he’s doing.

The "some fluid dynamic effect" may be the Venturi effect, increasing fluid flow speed drops the pressure , lower pressure in the tube lets atmospheric pressure outside the tube force the smoke into it...then again what do I know, I'm also an electrical engineer ;)
Hmm i see, venturi equation gave the efflux value of fluids flowing out of an orifice... I reckon it is the king Bernoulli itself
But then everything else is developed on Bernoulli's theorem so may be venturi would be more precise?
I'm not sure about the technical defintion of the venturi affect, or anything, but I can say for sure the root cause is the boundary conditions of the tubes. At the point where the inner tube discharges into the outer tube, you have fast moving inside flow, butting up against slow moving outside flow. The velocity of the flow can't change instantly, so you have a gradient across the edge, so they outside cannot be zero, it must have some greater-than-zero flow rate to satisfy the boundary conditions. Also, fast moving air has an inherently lower pressure, which can also work to 'pull' the air in through the outside tube. These 2 ways of looking at this could be mathematically identical, they are the same thing from 2 perspectives, or they may both share some portion of the force for the flow.
"Sucking" device based on a Venturi effect is called aspirator or vacuum ejector, or simply ejector. For example sandblasting machines suck sand just like that.
I made a Silver melting forge out of a trashcan and a Hair Drier.
strong enough to mix Brass, Melt Silver... Cant quite get gold and Copper to stay molten but made me lots of pretty aluminum sodacan bars and brass casts
You can also make a light bulb out of the filament too (well maybe an alert light bult) and it'll help keep you items of interest warm too....
You can make an incubator heater from it too.
The "HA! That's my daughter!" REALLY MADE ME LAUGH HAHAHH she's just like you! XD

Years ago I repaired the fan speed control resistor in my 1985 Honda with some surplus nichrome wire I had salvaged from some appliance that died. The fan speed had two open wound resistors wired in series . one resistor measure .25 ohms and the other .50 ohms. I was able to make new resistors and replace the two broken ones. I wound the nichrome wire around a nail then slid it off and opened the coil so the wire didn't short out on itself. Worked like a charm. And this is why I salvage anything that could come in handy some day.
That foam cutter looks extremely interesting as someone who builds RC foamies. The typical storebought foam cutters are usually a rod that makes it extremely hard to do anything but straight cuts cleanly.
That's what I was thinking
7:30 -The fluid dynamic effect is: if a Fluid gains kinetic energy, it must lose pressure...so the smoke is "pushed" by the air at atmospheric pressure into the tube, which is at a lower pressure due to the airflow inside.
5:50 the lick-ten-burger figures make a fashionable comeback!
But without the dying hazard!
i love the little detail of his hand smacking into the kiwico logo at the end there
I just like these videos.The time goes too fast while watching these and I learn so many new circiuts.
Plenty of cool ideas! Now try make something to blow warm air on your hair to dry them

2:02 "it BLOOOH like a fuse "
Electroboom
In prison in the 1990s I once harvested nichrome wire from a wirewound resistor from a broken CRT television. Then used the nichrome wire to build a soldering iron. Then I could easily soldier televisions I was repairing. 99% of the time when the televisions broke it was an electrolytic capacitor in the vertical or horizontal deflection circuits. You could touch a working capacitor to the ones on the circuit board without removing the old ones and when you found the right one the picture would work properly. Then remove and replace the bad capacitor. This could be done without soldering, but then sometimes the picture would go out again and the owner would have to jiggle the television. After awhile jiggling would not fix the problem. Soldering the capacitors in place worked much better. I usually charged 3 bags of coffee, about $8 to fix another inmate's television.
Another benefit was it provided me an extra unspoken level of protection. Since I was the only person who could repair electronics in my housing unit, mostly televisions, radios, and headphones, the other inmates didn't want anything to happen to me. Also I gained some trust and respect from other inmates since this was 100% illegal, but the guards never found any of my parts or tools. I had a bag of capacitors, a hex wrench to remove the bolts to take apart the televisions, and the previously mentioned soldering iron. It also helped that I weighed 235 pounds solid muscle from lifting weights 6 days a week.
@08:40 - Finally! (I was mentally shouting that at him at least twice before)
Mehdi, I love how you take things apart to see how they work. I feel like that kind of curiosity is something we all need to embrace and encourage, particularly among kids.
This guy is a genius teaching applicable electronics with comedy and something everybody has at home making it seem easy enough.
The first time I used a cheap homemade popcorn maker, it honestly reminded me of a hair dryer, and the first thing I thought was that it was made from repurposed hairdryer components to cut costs.
(At the core, it’s really just a heating coil and a fan, and said fan sounds exactly like a hairdryer!)
Great video. You should make a video on a CCFL inverter!
"hi, today we want to get into the amazing world of an hairdryer :D!"
_brutally murders said hairdryer_
Would love to see a series of videos on CRTs. I'm interested in building a CRT from scratch. While I've researched the topic I would love to have more information on how to control the beam, how to determine the voltages needed for deflection, what temperatures are required for the heater, etc... You do such an excellent job of explaining things that a video or series of videos from you would be beneficial!
There is a guy on CZcams who made his own clock crt, maybe check out / comment on his channel might point you in the right direction
I saw you in meme growing this is a first-time youtube recommended your channel I hope to see the amazing stuff you do. Good work
Mehdi, I honestly believe you are one of the very smartest science comedian out there. This here video was pure genius. The depth of your work does not go unnoticed.
Now that's how you do sponsored adverts! Also a standing ovation for putting it at the end of the video
6:58 ...doesn't get much truer than this in our modern age!

Hi, ElectroBoom, as a electronics student, videos like this really helps me to know what I can do with my electronic scraps here in my home. Great video btw
just remember to never go above 60V DC until you've learned to work safely with electronics. Over 60VDC and over 120VAC can kill you if you get stuck/touch them.

4:54 new information discovered, it's life changing 🤯
That thermal breaker operates similarly to a flame rollout on a gas furnace, except the flame rollout has to be manually reset, and if it’s a rollout, you need to check for issues with the flue and/or a cracked heat exchanger among other potential deeper problems.
Omg this guy is hilarious 🤣🤣🤣 follow him for years, such a legend !!!
