When he said single bridge rectifier electro boom's voice instantly poped in my mind saying "FULL BRIDGE RECTIFIER" before to my surprise electo boom showed up in the video.
so im not the only one, electroboom said exactly what i wanted to say
When his phone rang i thought: "it better be electroboom" aaand i was not disappointed.
Btw, your english is really good for a french, almost no accent and i wouldn't think you were from france when i heard you for the first time
Really good , like better than my own 🤜🤛
Yep
i thought he just lived there lol
he's French?
@@user-ej4eq5im4r well, nicolas salenc sounds french to me, and as another commenter pointed out, at 23:37 he says "oh, putain" (oh fck) someone living in france from somewhere else probably wouldn't say that
I'm a simple guy.
I see Mehdi, I click.
bruh
I see electroboom
Same
@@mousagaminyt4946 that's mehdi
Your English is very surprising. I almost had no idea you were French
lol
He french?
🙀 I thought he was a British guy living in France!
Really good, he says alright a bit like someone from Gateshead/Newcastle
@@JameisonAus_CZcams 23:37 an really frenchy Oh! Putain (oh fuck !) r
Just seeing a bills montage of the final product would’ve been boring. Seeing all of your fails and iterations was epic! Thank you for sharing.
Love the Electroboom collab.
Now That's One Amazing Project. I Love The ElectroBoom Part. 😄😂
Mehdi: "I mean shouldn't you know all this stuff already. What are you? A mechanical engineer?"
Nick: "no. I dropped out"
Mehdi: "you need full bridge rectifier... full bridge."
Ok. Full bridge rectifier. 9:50: interesting conversation.
when i listen that time , i am fall down in ground and laughing loudly. it was good one.

First mosfet can be: IRFB4227. Diodes: 2CL82 5MA 30KV, White propilene capacitor probably about 0,01uF 8000VDC, the gas dischargue tube something between A7-H25X and A71-H55X... The final mosfets could be the IRFP4227 which are in TO-220 format and powerful with low gate chargue, or a more low resistance and powerful IRFB7534PBF. Zeners is OK 15V 0.5W, and resistors about 100-1K, depending of the tank circuit peak voltaje and the frecuency, in order to have as less as possible the risetime gate charge. and I personally recomend using TVS on sensitive componets. I will try the same just to have fun. Thanks Nicolas!
Not all hero's wear capes! Thank you!
where can I find them?
@@dammo3355on the internet.
jesus christ thank you so much
One other thing for the insulation you could have tried is applying multiple layers of insulating lacquer on each layer of your coil. I've done that before and as long as you are somewhat consistent applying these layers lacquer - > coil you get usable results. Great peoject btw, now im in for a beefy arclighter 😅
Ironically, messing about with a high-voltage generator module from Amazon, I've discovered that great big enormous scary white sparks won't even set a cigarette paper on fire. You can send the spark right through it (a few CM long, decent spark) and there's not even a mark.
My arc lighters both use a much smaller arc. It's also, interestingly, purple rather than white. I think it's lower power and higher frequency. "WEEEEEEEEEEM" rather than "SNAP! SNAP! SNAP!" Looks like there's a knack to setting stuff on fire, not every electric spark will do.
czcams.com/users/shorts2-x3fDsOQG8
@@greenaum Just my non-professional guess: I'm willing to bet it's not that the arc isn't hot enough to light something on fire, but maybe instead that the material you are trying to light has tiny gaps in it and the arc is so thin that it might be simply passing through without ever making direct contact. Also would bet that cigarette paper is an even better insulator than air, which would explain why the arc might prefer traveling through those tiny gaps. Maybe if the paper was wet it would cause the arc to go directly through the paper instead of the air, but then of course it would *still* not ignite due to being wet.
I could be way off the mark here, but it feels like a hypothesis worth testing to me!
Excellent pace and presentation, Nicolas, even the embedded JLC PCB ad was slick and unobtrusive.
This guy just went through the entire history of engineering a taser.
Yeah, as an electronics engineer, he covered a lot of concepts that were taught to me in Analog electronics.
I guess many more that I didn't comprehend must be taught in masters
No one going to mention he blurred the mosfets for some reason?
They irfz44 probly
Amazing explanation! With your knowledge, I'd love to see your take on a coilgun!
Fantastic info and detail! Thank you. This was exactly what I needed!
It's a shame I didn't come across your channel earlier.
The video is stellar, keep it up!
Dude thank you so much! I've been trying to build a generator like that to PEF treat my food for some time. Your circuit is a great starting point, and now I'm not doomed to make all your mistakes. Thank you!
bro you blown up or not?
Nicely done, love the cross over with electroboom :D
For the how to avoid exploding the AVR question: from my experiments with automotive ignition coils. you'll wanna optically isolate the circuit to suppress the noise from traveling into the rails. however optical isolation will require power isolation too
Though there will also be an electromagnetic component of which I have no idea how to contend with
🤯😤😭😢🥺🤩we ⛽️ do it
Regarding optical isolation, can you get phototransistors for the right speed and power? I know, technically, _all_ transistors are phototransistors. All treated silicon is light sensitive, they just put them in dark containers to keep it out, or clear ones for the labelled opto parts. I wonder how fast one of those solid-state relays can switch? Really they're just a triac in a friendly box, with the input side driving an LED that sets off the output side.
I think speed is the important thing here, particularly switch-off speed to let the coil kick back quickly with it's back-EMF.
The "finished" version doesn't need a computer anyway, he was just doing that to test the parameters easily. Once they're known, you can do it in analogue. Even though coding an oscillator is easier than designing one!
How do you implement your opto isolation, Max?
czcams.com/users/shorts2-x3fDsOQG8
ASTONISHING VIDEO! The knowledge level is extremely high! You're brilliant!
Nicolas: I instantly figured out your problem with the MCU resetting. The resetting of the MCU is occuring do to very high voltage flyback from powering the inductive load. Make sure you place a flyback diode and/or bleed resistor around the coil. Guarantee it will help! Good work and awesome video!
Thank you for including ElectroBOOM
9:30 lol !!!! actually as soon as you said " puny single diode rectifier"
i remembered of Mehdi🤣 and that call killed me hahah
Why is your camera so bland it looks like you’re in 1944 Berlin
Wrong settings?
Brother is in an amateur horror film
wompity wommp
Looks like the video out of a RPI camera but I guess the white balance is off and that's why it looks weird.
As an electrical engineering student with everything i need to recreate this 5 feet away from me, I thought "I should do that!" then i realized I'm terrified of anything higher than 12v. I shall proceed taserless.
Holy fuck, how has this not gone viral? Such good quality explanations and video
its going viral now lol@@noname-gh5rs
A very nice overview. Going through the design steps and all the failures shows the terrible path you went through!. But you ended up with a working design. Congrats!
I use optoisolators on ALL data lines going to microcontrollers that interface anything with potential EMI, such as motor windings, which can also induce similar spikes from collapsing fields.
Great video. The electroboon collab blew my mind
Love the full bridge rectifier bit
Finally, after several years, there is now another decent stun gun video on YT! Nice job Nicolas. Guessing you seen our vid too? More great info there... Thanks for the quality content bro!
He he of course!
@@NicolasSalencPBP Great Vid, but I want to make one where the output power is adjustable! How can I do that? Sounds like it would be a great YT Vid? I will use it to train BIG Dogs, so I want it adjustable power cuz a dogs tolerance varies from one dog to another!
@@kennyh5083 That's not training, that's just animal abuse.
For a non-consuming HV switch with consistent trigger voltage, look at SIDACs and triacs which are used in gas igniter circuits for this purpose.
Making stepper motor drives I had interference issues. I solved those optically isolating the control electronics from the noise generating parts of the circuit. Although with the high energy here there may be some air radiated noise too? Still a lot of noise gets transmitted through conductors. So galvanically isolate your sensitive control circuitry from the noise as a start.
This was really good stuff. Incredibly informative. I’d just like to know a parts list or model info on the diodes and specs of the ferrite rods and hv capacitors. Experimenting with this sort of stuff is lots of fun. I’ve got a few ideas in mind and knowing some of the materials used would be fantastic
Nice try lmao
Particularly HV capacitors seem a right bugger to get hold of. Nobody sells them! I wonder if some concoction of aluminium foil and paper, wound into a spiral, would be practical? Maybe soak and pot in epoxy after. Or foil and plastic. You could even use cling film ("Saran wrap" for Americans"). Capacitance partly depends on the distance between the metal plates, closer is better. But closer also means less voltage resistance, it's easier to punch through a thin layer than a thicker one. Then there's the dielectric strength of the insulator. Simply, some materials are better, it's intrinsic to the material. Maybe TWO layers of cling film?
Thing is the stuff is so damn staticky it's almost impossibly to work with, you want nice orderly layers, no wrinkles. A press brake of many tons wouldn't help, it'd just squash up any wrinkles and ruin the result, tearing everything. Maybe if you used thicker plastic...
Maybe the professionals won the war on making caps decades ago... but there's just no marketplace for HV caps. I bet it's specialist suppliers with their own catalogues and high prices. Still, you can put ordinary caps in series, but you thereby lose a lot of capacitance.
Still, paper is cheap, so is foil. Might get myself a capacitance meter. Already got a high-volage supply to test voltage tolerance. Just have the insulator hanging over past the ends of the foil so there's nowhere to arc around. Be nice if you could squash it without breaking it but prob not. Maybe epoxy would increase the dielectric strength of the paper. Maybe, I dunno, WD40 would. Or light oil? Old microwave ovens have HV caps in them, but that's well in to the "unforgiving" end of experimenting, you don't get to make any mistakes at all with them.
@@legobuildingsrewiew7538lmao, hahaha, I want one too! 😂

@@greenaum unless you don't mind very low capacitance and efficiency, using regular aluminium foil and paper won't cut it. Seeing as capacitance is based on surface area, the trick is to use as thin as possible metal foil for the capacitor plates, kitchen aluminium foil is much too thick in that case. Commercially they use a super thin aluminium foil which is bonded to plastic, or even metalised foil which is produced by electroplating plastic foil.
Holy cow... this is really cool!
That's what I said!
Learned a lesson.
Thank you!
a new channel for my list of the betters channels about electricity 🔌 . love it
Le niveau de qualite de cette production est incroyable, tu merite plus de vues ^^

Your English too
This video could have been shorter by use of a ZVS circuit and flyback transformer. Two simple components found online. it's good to learn how to fail before success. Love the ElectroBoom part also!
That's exactly what he did use. A zvs driver, and a high frequency flyback transformer. Just not a pre built driver from ebay because it obviously wouldnt fit the enclosure.
Clear flex seal spray is a fantastic dielectric insulation/potting material. It is super easy to use and I have never had any arcs from components potted in clear flex seal.
Must get some. 👍👍👍
Great channel, subbed and love your style brother.
He should use optocupler between Arduino and Switching Fets and LC filter before both power supply to prevent spike to stop resetting the uC or preventing damage.
Really informative and you have a great flow of narrating your progress. I wonder why did you blur the values of the components, pressumably resistors, next to the mosfets? They are visible unblurred in the shot just earlier of that :) EDIT: Oh, you scratched up the mosfets and blacked out the resistors too. I truly doubt why was that necessary, considering that it's pretty easy to know what parameters you need for that type of circuit you show.
Best tip; insulate everything by single, means what can be disturbed in radius needs insulating as well as what will disturb other parts. Since Tesla energy is hard to go through glass rather than Plastic as well as air as the easiest, but electric wire is the most desired for electric as the most desired is the electric way interesting. As wires will always be desired through air. So an EMP bomb will knock out wires rather than the air. If there's no wire the desired will be water until it's air.
you did not provide any components details and winding information but after watching this video 2 times i figure-out full design and i am goin to try that and may be the video will be very soon on CZcams.
by the way nice video and great work

I like your name.
As an electronics engineer, I was so confident that I could make this when this video started. By the middle, I had given up
great work my man!!
To isolate the nano. I would say there is only one option. And it is to isolate it... completely. Power it from dedicated battery and transfer signal from it to power board through opto-isolator or signal gate transformer. And close it to all metal box of course.
I had all sorts of EMF problems making stepper drives. Optocouplers were the solution. That noise just comes right down the wires. It is like tuning into radio KAOS.
@@1pcfred This is why all of the large stepper motor drivers like TB6600 have optocouplers at all of their digital inputs.
@@TechBuild yes I figured it out on my own before the TB6600 existed. Although using optos causes other issues with timings. Optos that are commonly available are pretty slow. Which is why stepper drives have long setup and hold times. BTW TB6600s are not particularly large drives.
23:37 ce "oh putain" qui vient du cœur 😆 Je compatit, les Arduino et les courants parasites c'est une plaie 😅
Excellent video with the maths amd explanations.
SUBSCRIBED!
Nice tutorial 👌🏼 10/10
You know, that the diy stun gun is powerful as hell, when the guy, who built it doesn't test it on himself or his friends at the end of the video))
For those of you complaining about the part numbers being censored, please read the first 2 seconds of the video. Thank you 👍
Are you able to give the Stl file or is that a no?
You test on your self or sombody if realy works
Just need a housing for my stun gun
Can someone post these part numbers in the comments?
@pubg gaming hello
Nice. So close to plasma discharge at light speed. Interesting good work
Aerogels based on cellulose nanofibers can effectively shield electromagnetic radiation over a wide frequency range. Electric motors and electronic devices generate electromagnetic fields that sometimes have to be shielded in order not to affect neighboring electronic components or the transmission of signals.
For everything that’s already on this platform the fact that you decided to censor stuff is beyond silly
3/10 you didn't show any footage of you shocking yourself with it.
THAT'S A 150KV STUN GUN.
Definatly some trial & error on that build. Good on ya for sticking with it.
Very nice build Well done
Hi Nicolas!
I used high voltage generators (aka stun gun modules) in my art project ( czcams.com/video/a3Wc-ahGum0/video.html ) controlled by an esp32. During the R&D phase, I ran into the same problems you demonstrated in your video of controlling your stun gun with an arduino. I worked around this by using the esp32 to control a relay that switches an galvanically isolated isolated power supply. Specifically, I used the Meanwell SKA15B-05. Happy to share more if you're curious.
2 years later and still a great vid
very complete and very good video on the subject thanks a lot
You killed it man👍
dude ur awesome. I understood everything very well and enjoyed the vid. keep up the good work. u earned another subscriber
good you understand the whole process is pretty redundant considering he didn't say the output,,, meaning its shaky at best at what its suppose to do. most tasers use high amperage batteries like the 18650
Clever guy. Love it.
Wow, liked his determination! Awesome!
Thanks for sharing, grounded metal enclosure for the nano.
Cool info, thanks for sharing :)

Super awesome project!
Hi Sir Nicoles thank for the vidio sharing👍
once you have Mehdi one your side nothing can go wrong!
errr.... I mean everything will turn out fine after all!
great and easy to understand explanation!
Perfect cameo, was not undersold.
I like your video because you explain each point in detail. Can you please make a video on the RF amplifier using the 2SC1971 Transistor?
When I was a teen, I took apart a disposable Kodak camera. While pryingnthe plastic away from the circuit board, I wedged my middle knuckle against the circuit board, and got the ABSOLUTE WORST electric shock of my life!!!
I had no idea what had happened, as I just like taking things apart to see how they worked...
Cut to 20 years later, I'm scrolling through CZcams and see, "How to turn a disposable camera into a stun gun"!!!
It felt good to finally know WHY I got that shock as a teen. When it happened, let's just say I couldn't exactly search the internet.
imagine making an electric sword, absolutely terrific
Awesome vid bro!
awesome video!
Thanks for sharing. 😉👋🏻
Great video, thank you. For shielding you need a metal foil of very high magnetic permeability, meaning, MuMetal. The metal shield on the old oscilloscope tube are just that. Believe me, this thing works. All the old oscilloscopes use it.
Cheers, just ordered a roll
Source: Trust me bro.
@@NicolasSalencPBP You can also use a old automotive or other gas engine coil to jack-up the voltage!
@@hxd9321 No, that's pretty much what Mumetal is made for. Trust me bro. Or else go find out yourself.
Current that goes out has to come back. So, it's best to include the positive rail, with the negative rail directly on the other side of the PCB from the positive rail. Otherwise, you can end up making a big loop that will induce massive currents in other parts of the circuit.
It may seem like the current will return by the shortest possible path. This is only true at very low frequencies and DC. But as you know, pulses are AC. And it doesn't take very much frequency before the return current starts trying to follow the outgoing current as much as possible. There are some excellent videos on CZcams about this topic.
Very interesting comment 😊
4:23 I'm glad their's at least one other person with as many small storage bins as me, lol.
Unfortunately, I was so eager to obtain them, I paid way too much.
Really good work! How long did the whole process take you?
Wuaaah Men this video was amazing! I learned too much
Well explaned
I remember mythbusterd playing with one, it does switch from high amp low voltage when fired to high voilts low amp once connected . I think thats how Grant explained it.
Did not expect that Electroboom cameo
Exactly. Just deliver a full 200kw contentious to the attacker 💥
THAT CAMEO WAS UNEXPECTED!!
I thought this was an electro boom video. I just reading 150,000 v stun gun and clicked. I realized while watching it obviously wasnt electro boom but then he appeared my mind was blown.
Bro every electrical vid I watch there is electroboom in it and i love it😂
You always love to see a PkCell
6:28 In the US they call a coil like this in conjunction with a relay which disconnects as soon as it is activates (causing the relay to oscillate rapidly) a buzz coil... Very effective for engines which have no set ignition setting like a hit and miss engine...
It can also be used to extract poop (violently) from an unsuspecting victim...
VERY GOOD. Thanks of Brazil🎉😊
Merci, grâce à toi j’apprécie (enfin) l’élec en prépa 🥶
I watched this whole video without understanding a single bit about the way it works, is built, or how any sort of electrical knowledge😂 BUT LOVED IT ALL AND WANT TO UNDERSTAND😭😂
Hi Nicolas. You made a really good job there. Congratulations.
I think the problem with Arduino nano are the cables (also the proximity of power traces in your board), but cables are definitely a huge problem, if you try with Arduino nano soldered in the main board I think that could work properly.
Could you send me the measure of output waveform? If so, do this with a 600 ohms power resistor at output (between electrodes), this should make voltage drop to under 7000V.
Thank you in advance, and again... Well done.
Love the Electroboom cameo
