ElectroVLOG series is available to my Patrons earlier, so don't be confused about some comments being a month old!
ElectroBOOM Hello I love your vids
mind= blown lol
Fill it with different noble gases and go over the differences! They usually use Argon for plasma globes IIRC.
More like ElektroDoom
fill it with noble gas we want to see it please!
the only problem I have with this channel is that there's not enough videos. keep it coming
needs patreons man

No other channel gets me as excited with a new video like this one.
lmao even for Squidward
thanks for showing that experiments not always work.
Vaibhav Gupta It would have worked... if he would have wrapped at least 85 layers of scotch tape over those secondary windings.
I have one of those inexpensive plasma globes. I wondered what was the difference with your vacuum coil. Thanks for explaining.
His vacuum coil is just a Tesla coil in a vacuum, electricity can jump across large distances in a vacuum so putting a Tesla coil in there is not a good idea. Plasma globes on the other hand use a flyback transformer, which is located outside of the vacuum. The output of the transformer is connected to the conductive ball inside of the transformer. The electricity travels from that inner ball to the glass sphere surrounding it thanks to a partial vacuum and a mix of gasses that give the plasma cool colors and movements.
Yes, i support Mehdi on Patreon.
Wtf...it's been an hour this video has been uploaded and this comment is from 1month ago???
Commented 1 month ago? Time traveler? WTF?
1 month ago ??? WHAT THE FUCK
I love how you add comedy and still keep your videos educational and entertaining at the same time. 😊
Medhi you've inspired me to go back to school and become an engineer !
@@J05TI he OD'd
Mehdi that is.
You are the best man. Your humblety, despite being so knowledgeable and your sense of humour are contagious (the humour I mean, I wish genius was contagious). Thanks for making these Mehdi.
This free energy devices constructed with a *FULL BRIDGE RECTIFIER* and mehdi's unibrow has saved me a lot in my power bills. I know Mehdi said his unibrow could be held hostage, but if it's giving out this much energy with a *FULL BRIDGE RECTIFIER* I'll just shock anyone who tries to steal it.
1:09 "hmmm he hasn't gotten zapped yet..... nevermind"
dont worry mehdi the videos where still fun to watch and it was exciting to see how your coil would behave in a vacuum :)
I like the part where he uses air inflated bubble wrap as an insulator in a vac tube and it keeps outgassing and stops insulating.
Your scripting/acting is actually very good.

Nice demonstration, not only funny, but neatly explained. Thanks!
Im so scared to open up a computer's power supply and hes doing all of this, what the hell?
Because he knows what he's doing :D
And its good you are afraid of opening a power supply because the charge the smoothing capacitors hold can even kill you when unplugged. Keep the dangerous fun to people who know what they are doing.
When a reply gets more likes than the comment, i cri ;-;
Well, wear rubber gloves if you do decide to open it, they'l resist 120V or 240V well enough, and hold a 100k resistor across the capacitors for about 20 seconds using a pliers. I'v replaced light switches without turning off the power using rubber gloves.
Why wouldn't I turn the power off? I couldn't determine at the time which breaker it was on at the time, so I put on gloves and replaced it anyway. Turns out, it was connected to another room's lighting circuit. My house has bizarre wiring paths, like the outlet in one room connected to the basement lighting circuit below it. This place is older, and though the wiring is nice and thick, and in good condition yet, it lacks grounds and some predictability, that's for sure.
when you open the power supply, shortcut the capacitors, otherwise you can get a shock if you touch them
Why not fill the vessel with farts?
Explosion ensues
And other gases? Like pure nitrogen, pure hydrogen, or pure carbondioxide? Might make interesting colours....
Eliphas Leary pure hydrogen would go boom aswell I believe ?
Not necessarily. If there's absolutely no oxygen, the hydrogen won't blow up.
BT7M you're right I forgot about that.
this video was fast as fuck !
yankov_xxx360xxx_ haha faf
im fast as fuck boiiii
you fuckin beat me to it boiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii
rabbits:P
i sure did
0:11 That's the kind of goof that made me subscribe to this channel.
maybe you could have the coil outside the vacuum chamber and run a thin wire to the top load inside the chamber, this would not let it arc to the primary
I really wish I could afford to support you on patron but i can barely afford the internet to watch your videos. All I can do is say thanks for your hours of educational entertainment. Hopefully you can get some corporate sponsors some day
I love this Tesla series. Thank you for sharing your failures...makers/tinkerers always experience this, and it's healthy for people to recognize that their failure is normal.
Fails:
1:10
1:21
your turn around towards the camera was awesome
I wish my college professors were as instructional and funny as you
1:10 oo man that scared the heck out of me....the volume was high😂😂
so close to that 1 million mark
I hope you reach it this year.
Hey thanks for revisiting this experiment anyway!
2:25
''Am your failure, don't look at me''
That was a naughty arc! Shorting your tesla and hiding from the camera!
"This project is like beating a dead lizard... it's not going to run!" How are you not at 1M subscribers yet?!
You are the best teacher ever!
Very amusing video. :-)
best thumbnail ive ever seen
1:13 Is that the *FULL BRIDGE RECTIFIER!?*
3:29 fantastic analogy
1:20 that is damn cool
Helium should work for this I think...
Instant like.. Even before video is done loading!
Protip: 1. Put a ground plane below the secondary, so the current from the bottom of the winding has somewhere to go. Ideally it should be grounded to the circuit ground in the driver, and maybe whatever other nearby grounds you can find (safety ground, mains, your body.. :) )
2. Wrap the secondary with a strong insulator, like polyester or polyimide tape, or varnish. (If you use varnish, use a clear polyurethane, apply several coats, then bake it to ensure it's cured.)
The problem you are having is because of the anomalous breakdown at Low pressures. Instead of reducing pressure over the inductor coil, why don’t you insert the inductor in a tube which is at a higher pressure by sealing the tube thus creating a pressure differential? This will ensure normal gas breakdown near the inductor while the corona ring at the top is at lower pressure. You should get a glow plasma discharge in the entire tube. We usually use this trick to ensure that there is no anomalous discharges.
Look at this man the pressure of the graph splitted my silicon washer in half
Not only that i saw that the tower was actually arcing from top here to bottom there
Don't give up mate. You can think of another material for the tower!
love your videos, kudos from the bronx
"This project is like beating a dead lizard..." lol
Glad to see the coil isn't dead.
"LAST attempt"
Sure... we already know how this is gonna end...
1:11 Ouch! f****** s*** Beep-beep beep. f***. sometimes you just want to test something quickly but it's never quick isn't it?. 1:09
You need to submerge the coil in thick electrolyte, something that does not evaporate quickly or explode in vacuum, maybe some kind of a resin. Or you can use a second chamber to keep the coil at high pressure.
Always enjoy your vids. Cheers
I wonder if you really heavily insulated the bottom and the other areas near the bottom of the coil would lead to the coil not shorting to itself like that.
Though with how the vacuum seal broke, it may not work until stronger materials are used.
Thank you so much for your awesome videos! This has been an inspiration to pursue Electrical Engineering.
I love your Unibrow! It's iconic now!
where I work, we are told the pink bubble wrap is ESD safe which usually means it is conductive, or at the very least, not an insulator.
You should've coated the secondary in varnish or epoxy so it doesn't breakdown so easily.
Hint from research lab: no wood allowed in vacuum chambers! Wood is a giant sponge which spews H2O-vapor and air. Even aluminum does the same. (This only becomes important if you're trying to use pure gas mixtures with no oxygen or water vapor.) Quick fix: paint wood with epoxy.
You sir, are crazy........ thank you! Like your channel. pierre from New Mexico
My kids will love this video
Out of interest. I used to be a technician on a 3 million volt Cockroft-Walton type nuclear accelerator.
Around the high voltage generator parts, the LAST thing you want is a vacuum. In fact, we had the whole generator cased in a pressure vessel at 6 atmospheres of SF6. The output fed into an ion source (in vacuum) and a beamline that ran down the center of the pressure chamber and exited at the ground. The result was a 3 MeV beam of protons, deuterons or alpha particles depending on the gas fed into the ion source.
Shouldn't be too difficult to build one...
I believe that in the commercial ones the primary coil is out of the vacuum sphere, this prevents elecrons to easily travel from the corona to the primary.
If you connect the bottom of the tower to a steel bar next to the tower (inside the chamber) it would arc betwenn the steel bar and the top of the tower so it should prevent the tower from self-arcing
dude, love your vids man, keep being awesome!!!
The reason you had the tesla coil arcing to it self is because it's over coupled. Unlike a normal transfomer you don't want all the coupling you can get, all you need to do is reduce the angle of the primary coil and that should stop the unwanted arching. A general rule of thumb is to not go above 45% but lower than that would probably be recommended.
I really love your videos,very interesting
1:53 Close your eyes
"It is running away from me!" Where else can it go???!!!
try leaving the coils outside of the vacuum chamber and run a from the top of the secondary into the chamber and to the top load. you will likely need some fancy insulation for the wire, but once you depressurise the chamber, it will become the low impedance path to ground and thus the majority of the arcs will form inside. At least that's what I hope they will do.
Yay, I knew theres gonna be another video with the beloved tesla
you insulated the secondary with bubble wrap, which has both a low dielectric strength, has trapped air just waiting to be excited, and is very thin. It's not surprising that it didn't work. Get some PTFE (teflon) heat shrink tubing and slip it around your primary. It will give you at *least* 1400 V / mil (55 kV/mm)
A silicon or PTFE (teflon) mat would also do the job if you cut a hole for the secondary slipped one through, and sealed the interface with some silicon caulking.
I came for the electronic videos, I stayed for the explosions...
The arcing at the bottom of the tower is why Tesla used a flat coil. Konstatin Meyl also uses a flat coil design for his wireless power transmission. But I guess if you used that design, there would be fewer explosions. :P
Maybe the air-filled bubbles burst under vacuum, since the air inside them is pressurized and that is why the arc moves to the bottom. The electrons find a path to flow to the coil at the bottom. If you wrapped it with a trash bag (or any other plastic for that matter), maybe it wouldn't do that.
You did it it’s a success
One time i was messing with those glow balls one time. Touching the outside and watching the arcs follow my finger and the SOB shocked the hell out of me. WTF man i didn't think it would shock the sh*t out of me. I have been afraid to touch one ever since.
That's what she said... 2:31
@2:33 I died laughing you got a new subscriber👍
In the middle of a soldering session, this pops up.
Precisely!
#relatable what were you soldering? I just finished a tda2050 amplifier. That thing was LOUD!!!
+Ivan R
I was working on a capacitor charger I designed.
What's the power of the amp?
the amplifier was a 50 watt tda2050 single supply design. I had quite some fun with it after I got it to work. For some reason, it did not work as well when I connected the speaker between a capacitor bridge. Not sure why, but I think it might have to do with the internal design of the ic.
+Ivan R
Maybe there was some DC leakage?
Mehdi, have you thought of using a slightly larger PVC pipe over the coil tube as an insulator? That or several layers of electrical tape should prevent the undesired arcing.
Electrical tape plus pvc pipe plus electrical tape should do it :)
Kapton (polyamide) tape would be best, but more expensive.
A better option would be to do what we do with high voltage transformers. Dunk them in oil. Just leave the top load above the oil.
Or just do what most amateur coil builders do and dunk the secondary in polyurethane. Super cheap. Easy. Neat. And easily accessible. I use polyurethane for my coils. Seven bucks for a large tin that will last me for years. It looks really nice too.
+Jammit Timmaj I dont think it would be good to dip them in oil because this is in vacuum.....
Can anyone explain why that arc repelled him ? And also why that spinning ion propeller was making that sound whenever he moved his hand closer to it 1:32 ? Plz help ...
I always watch the ads on your channel I even click on it so you can create more money!!
tesla coil needs to be in air, but the top load can be inside a bell jar, stick top load in bell jar, run wire through the vacuum chamber to top load.
Man, you don't put the whole tesla mechanism inside the vacuum and not have it shortcircuit itself, you are asking too much from it. Play with its output, is still works in normal atmospheric pressure, use its output on other nice plasma vacuum projects.. or otherwise use the FULL BRIDGE RECTIFIER and make dc liquid ion propulsion in atmosphere (look at electrospray)
Theres just something funny about watching an electrician , carpenter or other tradesperson just going "oh fuck, oh shit. shit" every 5 seconds when something pops or goes wrong
omfg lol when the circut popped I jumped and my phone flew out of my hand LMFAO lol XD
I'm happy!
you should try super saturating xylene with styrene from styrofoam peanuts and packing material, so when it is done you can paint it on the coils down below to get an incredibly strong barrier to arcing *they use it to make home made coronal dope so I am betting it would work far better than bubble wrap, and no need to pop it to keep it from exploding in a vacuum lol.
Anyone have this feeling that this guy have the same face as the guy in the sketch picture that if you stare at him he will appear in your dreams.
Bubble wrap has air in it. When you vacuum the chamber, bubbles pop and release some air. And then, air which comes from bubbles ionizes and gets conductive. This is why your coil crashes.
his comedy is just cheesy enough to be funny and not cringe worthy
love your vids :) they are funny and interesting.
1:09 i seen the power supply go to constant current when the capacitor blew up haha
probably did that as a jump scare
pink bubblewrap is somewhat conductive. bad insulator to high voltage.
that's why its used to prevent ESD.
use electronics lacquer.
ELECTROO VLOOOOOOOOOOOOOOOOOOOOOOOOG LoL
Soso Salsa dat harmony 😂😂
VLOOOOOOOOOOOOOOOOOOOOOOOOGAH!
"Where VLOG stands for logarithmic voltage."
why don't you isolate the vacume to only be at the top of the tower and the rest in normal air and pressure. So feed a small wire through the base of the vacume chamber and have the metal coil in the container it can reduce the loss of energy in 1 location that is undesirable.
the reason it was arcing to the tower was because in a vaccum there is nothing containing the electrons or hindering the distance they can travel to do this successfully you would have to make sure the toroid is in a vaccum but the tower is not to prevent it from arcing to itself
I saw you on Granville Island on Sunday!!!
When everything fails, hot glue the *FULL BRIDGE RECTIFIER!*
you should try to put the whole set up (including the primary and sec coil outside and put the top load inside(I dont know if it would work,just a random idea)
love your videos
I'd love to see some DIY videos here ...and by that I mean: he does things himself, and we don't ever try that at home.
1:15 that's diy for you in once sentence...
the vacuum can't create a plasma when a high voltage is in.but there's no resistance and the electron can easily emit to the proton.
Perhaps you could keep the coil outside the vacuum chamber and leave the top inside the chamber connected by wire, just like you did with syringe.
BTW, I tried with syringe and the spark melted a hole in seconds, ouch!
