The arc going through the board might've been more painful because of less stray arcs dispersing energy through the air (also smaller air gap), resulting in a more energetic pulse?
8:56 It's missing a few things: Safety: - Add a fuse at the input to protect against overcurrent. - Include TVS (Transient Voltage Suppressor) diodes for protection against voltage spikes. Efficiency: - Replace the DC-DC converter with a more efficient modern equivalent. - Optimize the transformer design (FB1) for better coupling and reduced losses. Control: - Implement closed-loop feedback for better output regulation. - Add soft-start functionality to reduce inrush current. EMI reduction: - Add a common-mode choke at the input. - Improve layout with shorter traces and better grounding. Thermal management: - Add heatsinks to Q1 and Q2 MOSFETs if they're getting hot. Reliability: - Use higher quality capacitors, especially for C2 and C3 which see high voltage. - Add snubber networks across the MOSFETs to reduce switching stress. Flexibility: - Include trimmer potentiometers for fine-tuning output voltage or pulse width. Monitoring: - Add current sensing for overcurrent protection. - Include voltage monitoring points for easier debugging and adjustment.

Just a head's up, the insect you show at 1:27 is called a "Brown Marmorated Stink Bug" and are both an invasive species and SERIOUS agricultural pest. I normally would be against you killing bugs but this is one where you'd actually be helping the ecosystem by killing any you see outside of China or Japan. (Heads up for those in Europe, there are some less common native species that look VERY similar. To identify the BMSB, the markings unique to that species is alternating light/dark bands on the antennae and/or along the back edges of the abdomen. "Marmorated" means "like marble". If you look up pics of the BMSB and The "Forest Shield Bug", you'll see what I mean.) To my knowledge, the green ones are okay, but if someone has more detailed knowledge on it, feel free to correct me.
It's possible for sure. I've been wanting to repair an old USB 2 charging port on a laptop with USB C, but I've been out of flux and lazy to buy any lmao. Just an old laptop for projects anyway. Still, with a little equipment and some dedication you can basically swap any port for a compatible one
It reminds me a guy from ages ago who attached a bunch of USB 3.0 boards to a large server motherboard that had the capacity to handle all of them together and then made a huge array of cables that went connected from all of the ports on each card onto a homemade DC to AC converter that also transformed the electricity up to an output of 120v AC and used that juice to hook up an electric pan and cooked his meal on it, it looked janky and it was probably dangerous but it was hilarious at the same time, kinda like what eletroboom does, shame that I'm not able to find that video anymore, it was from 2008 or 2009 approximately, funny though that guy also looked Arab and I remember the video having subtitles despite of him talking in English with an understandable accent, so yeah USB can power anything if you're creative enough. ⚡🔥
Most things with batteries wouldn't need that sort of dummy usb-c port. It's only things that you have naked leads or things that need to be connected to an external battery or power supply that would need it. Most people don't really... ever... have something that needs to be connected to a power supply like that.

Pain in insects is an interesting topic. It seems it's more of a status check for them and not necessarily a signal like ours that generates discomfort. There are many insects which continue eating food while being eaten by other insects, for instance. Then again it might be comfort food.
If you have 1 liter of water at 37 degrees Celsius and you're using a 1000 watt hot plate to boil the water, you can use the following estimate to calculate the time it takes to boil the water: Energy (joules) = Amount of water (grams) x Specific heat capacity x Temperature change (°C) Energy = 1000 grams x 4.18 J/g°C x (100°C - 37°C) = 251,000 joules The power of your hot plate is 1000 watts (1 watt = 1 joule per second). To convert joules to seconds: Time (seconds) = Energy (joules) / Power (watts) Time = 251,000 joules / 1000 watts = 251 seconds It would take approximately 251 seconds to boil 1 liter of water from 37 degrees to the boiling point using a 1000 watt hot plate. That's roughly 4 minutes and 11 seconds. The time may vary slightly depending on factors like the initial temperature and the efficiency of your hot plate.
@5:53 DC to DC converters are converters not inverters, i.e. not DC to DC inverters. The output of an inverter is AC, which, if driven from DC, is a DC to AC inverter.
Mehdi smelled the back of his hand to check for burnt hairs and then goes outside and performs CPR on a stink bug! 😂🤣😂 We all love this Nutty Professor!
The way you explain the schematics is so helpful! As a student, I've only learnt what each component does and its calculations but when put together in a practical application circuit I don't know how to understand a schematic not done by me D:
There were early experiments on partial rectification of AC voltage with differently shaped spark gap electrodes in the air. This is what shocks you when you hold different metal objects to a Tesla coil spark. A certain percentage of the AC voltage is rectified and the current of the Tesla coil suddenly has a DC component. It works best if you only touch the longest sparks. You know those huge black ignition coils from 1900 when X-rays were discovered in vacuum tubes? They were low frequency, had an iron core and were non-resonant. It was realised that when generating air sparks with these coils and one electrode being a needle and the other a disc would produce longer sparks than vice versa.
Your first question about the prototype board hurting more is the charge selects the string of circles leading towards your fingers. The distribution of cathodes of the gun and the 2nd device cause parallel lines to run towards your fingers, then also vertical lines of discharge with the charge flowing into the air at the top and the bottom of the board. Then at some threshold of discharge into your fingers this flow is an easier path for the high voltage than flowing on the verticals paths and more of the charges moving vertically and horizontally but not visible (with the copper circles acting like little capacitors) all rush into your fingers. I can see it. Wait, wait, hmmm, okay yes, I can see it mentally.
Can honestly say I learn SO much from ripping things apart, AND......... watching ELECTROBOOM!! then trying to put them back together! And maybe the board has less RESISTANCE THAN THE AIR, Mehdi! so the energy is HIGHER when it hits your GROUNDED BODY!! WE love you Mehdi
You should explain GTAW Welding machines (Gas Tungsten Arc Welding). They use high frequency AC to strike an arc from the tip of the tungsten electrode to the base metal being welded. This arc melts the metal into a pool and metal is added to it.
0:48 to answer your question, the prototype board is more conductive than the air therefore it hurts more cuz the copper in it allows more electrons to pass through it and to get to your hand
Have you ever considered making a video about Mercury Vapor Rectifiers? They are an awesome piece of electrical history that is slowly being lost to time.
At 10:47 i think your explanation might be missing the effect of those L1 and L2 inductors, i think they accumulate energy as the mosfet opens (nothing flows through the primary yet) with a slowly increasing current which might also help with switching losses, and only after the mosfet switches off the current can flow in the direction shown (through the primary resonant circuit), except through the capacitor C2 (or C3 for the second pair) instead of the mosfet. I think it acts kinda like a crude boost converter and also probably greatly decreases the change of blowing up mosfets because they dont have to switch off that inductive current.
I have to say I'm a senior studying mechanical engineering and I'm currently take an intro to electrical engineering class right now and I have never been so lost in a class in my life. God bless you for actually being an Electrical Engineer cause I can't understand any of it.
Mehdi is my hero because he is smart with electronics and he is funny! Not all heroes wear capes. Mine wears normal clothes and gets electrocuted periodically! Lol
0:16 The four basic rules of Tesla coil safety: 1. Always Keep Tesla Coil Pointed in a Safe direction. Never point your Tesla coil at anything you do not intend to shock. 2. Treat All Tesla Coils as Though They are Running. 3. Keep Your Finger Off the Button until You are Ready to Shock. 4. Always Be Sure of Your Victim and What's Beyond Them.
I sent another RUclips channel towards you because he is trying to build a hover board but he doesn’t know the first thing when it comes to covering wires and protecting them so I figured you would be able to help him and teach him a little bit about how he can Save his hover board and also protect the wires from water
when I was at TI last Summer, i got my hands on a pre-RTM board that allowed you to get 9, 12, 15, or 20V out of it with a programmable current limit via dip switches. we used it to power some EVMs with docking station power supplies which were capable of up to 100W.
1:22 I can't be the only one that immediately heard in their head the song lyrics "absolutely nothing! Say it again now!" ... Just me? Oh. Okay, I'll see myself out now...
3:50 ... Well, I've swallowed (and passed ... eventually) a camera. It had a cool wearable computer pack (for which I had to sign a waiver promising not to wear it on public transport or aircraft) with a screen so it was possible to see the camera output in real time. I nearly had an MRI with it still inside me. It was only saved by an X-ray I needed a few days prior. Had it not been found, it would've shot OUT of me like a bullet in the magnetic field of the MRI. Cool. #coolstorybro
They likely only use a resistor on that "PWM" line because the "PWM" signal from the controller is probably driven with an open-collector output, which means it switches between "pulled down to ground" vs "allowed to float" (it is never driven with a positive voltage at all). Essentially, the transistor driving it already serves the purpose of the diode in that case.
I worked at a monitor repair facility. I wasn't too good at repairing part of things (the flyback transistor was no joke). But I did have one of these guns to clean the tube contacts and I was responsible for scan line alignments.
Interesting video! I recently bought a device from China that can output any kind of voltage and ampere upto 32V from an input of 6V to 32V. I don't know much about electronics but I was able to charge a trimmer with it. I got an adapter set with basically all charging connectors in existance and connected a car lighter plug on the input. So now I can theoretically charge anything in my car. I hope nothing blows up......
Also note the pancake style flat tesla coil: The coil is mounted right above an aluminum heatsink: since the coil is air-cored, The induced eddy current losses from the heatsink will decrease the output
Unfortunately you cannot run everything on a battery pack. Battery packs need to activate the DC to DC switching inverter to increase 3.7 V from the battery to 5 V or above. The problem is that this inverter constantly draws power from the battery, even if nothing is connected to it on the other side. So the battery would run flat in a few days without even powering anything. That's why almost all battery packs have a sensor that will completely shut off the inverter unless a certain amount of current is drawn at the output port. The problem is that some devices draw so little current, that the battery packs shuts down the inverter even though there is a device connected to the output. E.g. if you run a Raspberry Pi on a battery pack and it's CPU goes idle, it will draw so little power that most battery packs simply shut off. I also have a radio controller with LCD screen that I can use to control certain house electronics and it also draws so little power, that it won't run from a battery pack (it will work for a few seconds when I connect it, then the battery pack shuts down the inverter again). You can prevent your battery pack from shutting down like this by adding a resistor between power and ground that ensures a certain amount of current is constantly drawn at the output port, but that will only make the battery run flat even faster than with the inverter being constantly powered alone and all power going through the resistor is totally wasted energy that only produces some heat.
Best channel on RUclips hands down. I don't give a damn about electricity or know anything about it , but i binge you and learn allot cause i like seeing you get shocked 😂 because usually when you are shocked it's usually something i would do that did it lol. just don't die medhi we love you!
5:56 Isn't it supposed to be a dc-dc converter? "Switching inverter" is usually a term for dc to ac switching supples and while they are topologically the same their control circuits are different
Taking stuff apart is always fun ❤ I wouldn't know half as much about electronics if I never took stuff apart. Definitely want to see this as a series!
I honestly don’t understand anything you’re saying Mehdi when you do your small “lectures” in your videos but I enjoy listening to you just as much as I love watching your videos.
I love the idea of a bug killing handheld tesla coil personally. I really want one of those but a lot more powerful, to the point where it just roasts any fly i hit with it
I have had an overwhelming curiosity about everything in this crazy existence we all share for as long as I can remember. It’s the primary (pun intended) reason I watch your channel! That said, I have always freely shared what I know with others. It took a lot of aging before I realized how arrogant and annoying this can be. I’m jealous, and yet very thankful, you can monetize that which you enjoy, Mehdi! I know i will continue watching your channel for as long as I am able! 👍🏼 Thank You for sharing your knowledge! 😊
Same happens to me, I learned a lot of stuff from different topics because I like to learn stuff, so I always have something new to talk about and when I'm with other people usually happens two things; or they don't care and don't wanna hear what I wanna tell them or they're willing to hear but doesn't know what the hell am I talking about so it ends up being a one way conversation and I get bored for not having someone to bounce ideas with and the other person maybe it's interested but finds the info difficult to understand so they end up bored as well, so across the years I learned how to tune down my crazy man ramblings to a more regular level to engage with regular people or else I would probably be an introverted weirdo who doesn't talk to anyone xD
@@MrLind87 What did you just call me?! 🤣😂 Yes, I understand completely. I decided if I ever marry a pigeon, that is when I know I’ve gone nuts. The last guy who did that gave the world so much! He died completely alone. 😢 A few years ago, met some motorcycle friends at a local brewery. Was told where I should sit because “you’ll get along with those guys; they’re engineers.” 🤷🏻♂️ Asked them about their bikes. They replied that this was the first two-wheel Wednesday they’ve attended for the last 2 1/2 years. “We’re celebrating, actually. We just completed a project that took us away from hanging out.” I congratulated them and asked them about their project. They described their build and spoke about how close the tolerances were. I got all excited and said, “Wow! At those tolerances, you would have to worry about gravity during casting the…..” and on and on I went. Eventually, I stopped and told them it must feel great to get that done. “What kind of engineer are you?” “I’m not, I sell motorcycles.” They said I had just described all the obstacles they had to overcome to get it done. I confused them so much, they avoided me the rest of the night. A friend’s husband came over to my dealership to take a look at a bike for himself. “I knew you would tell me the truth about riding.” Afterwards, we spent the next 2 1/2 hours talking about Nuclear power. He was some sorta specialist at the local nucular station. 🤷🏻♂️☺️👍🏼

The difference between mom and dad.
The arc going through the board might've been more painful because of less stray arcs dispersing energy through the air (also smaller air gap), resulting in a more energetic pulse?
More surface area contact, better contact
And also the fact that the air would have more resistance than the board
I think it has to do with the capacitance of each piece of metal that its arcing between, not sure tho.
@@agentmith More surface area means more surface for the current to spread out through which in turn makes the shock milder.
@@usernotfound-dd1pd Interesting idea, but keep in mind that a shorter gap (or many short gaps in this case) would also mean a lower voltage.

The distribution of cathodes of the gun and the 2nd device cause parallel lines to run towards your fingers, then also vertical lines of discharge with the charge flowing into the air at the top and the bottom of the board.
Then at some threshold of discharge into your fingers this flow is an easier path for the high voltage than flowing on the verticals paths and more of the charges moving vertically and horizontally but not visible (with the copper circles acting like little capacitors) all rush into your fingers. I can see it. Wait, wait, hmmm, okay yes, I can see it mentally.
6:40 Really Sacres 💀
I was using headphones and I'm now deaf
Can honestly say I learn SO much from ripping things apart, AND......... watching ELECTROBOOM!! then trying to put them back together! And maybe the board has less RESISTANCE THAN THE AIR, Mehdi!
so the energy is HIGHER when it hits your GROUNDED BODY!! WE love you Mehdi
1:56 "test-subject"
Did Mehdi play Protal?

You should explain GTAW Welding machines (Gas Tungsten Arc Welding). They use high frequency AC to strike an arc from the tip of the tungsten electrode to the base metal being welded. This arc melts the metal into a pool and metal is added to it.
15:12 @ElectroBOOM call it “Tweaker-Time with Mehdi”. Tearing stuff apart for no reason has rather large following.
0:48 to answer your question, the prototype board is more conductive than the air therefore it hurts more cuz the copper in it allows more electrons to pass through it and to get to your hand
Let's vote for Mehdi to make a tesla gun himself
Have you ever considered making a video about Mercury Vapor Rectifiers? They are an awesome piece of electrical history that is slowly being lost to time.
Wonderful! Teardown channels have taught me an unimaginable amount about electronics over the years, so I’m always happy to see more Teardowns! 😊
3:32 Holy Mehdi is my new god
3:51 to be honest i don't really expect you to really eat that 🤣
How to die
At 10:47 i think your explanation might be missing the effect of those L1 and L2 inductors, i think they accumulate energy as the mosfet opens (nothing flows through the primary yet) with a slowly increasing current which might also help with switching losses, and only after the mosfet switches off the current can flow in the direction shown (through the primary resonant circuit), except through the capacitor C2 (or C3 for the second pair) instead of the mosfet. I think it acts kinda like a crude boost converter and also probably greatly decreases the change of blowing up mosfets because they dont have to switch off that inductive current.
the jumpscare when you plugged in the usb decoy got me good
Agreed
The wire around the 3d print looked amazing, if not for the noise, would make for a sick decoration!
I'm not so sure if it's a good idea to shock a Stink Bug!
IMO they smell like green apple jolly ranchers. Not stinky at all.
I have to say I'm a senior studying mechanical engineering and I'm currently take an intro to electrical engineering class right now and I have never been so lost in a class in my life. God bless you for actually being an Electrical Engineer cause I can't understand any of it.
Mehdi is my hero because he is smart with electronics and he is funny! Not all heroes wear capes. Mine wears normal clothes and gets electrocuted periodically! Lol
Except he does wear a cape sometimes (as "The Rectifier")
0:16 The four basic rules of Tesla coil safety:
1. Always Keep Tesla Coil Pointed in a Safe direction. Never point your Tesla coil at anything you do not intend to shock.
2. Treat All Tesla Coils as Though They are Running.
3. Keep Your Finger Off the Button until You are Ready to Shock.
4. Always Be Sure of Your Victim and What's Beyond Them.
This is the most insane video in ages. You had me in laughing tears
I sent another RUclips channel towards you because he is trying to build a hover board but he doesn’t know the first thing when it comes to covering wires and protecting them so I figured you would be able to help him and teach him a little bit about how he can Save his hover board and also protect the wires from water
Thomas Edison be like: 1:27
when I was at TI last Summer, i got my hands on a pre-RTM board that allowed you to get 9, 12, 15, or 20V out of it with a programmable current limit via dip switches. we used it to power some EVMs with docking station power supplies which were capable of up to 100W.
1:22 I can't be the only one that immediately heard in their head the song lyrics "absolutely nothing! Say it again now!" ...
Just me? Oh. Okay, I'll see myself out now...
YA!
Me after mehdi explains how the Tesla coil gun works: "I understand... nothing"
This guy has built up so much of an electricity tolerance he could get struck by lightning and continue making videos
3:50 ... Well, I've swallowed (and passed ... eventually) a camera. It had a cool wearable computer pack (for which I had to sign a waiver promising not to wear it on public transport or aircraft) with a screen so it was possible to see the camera output in real time. I nearly had an MRI with it still inside me. It was only saved by an X-ray I needed a few days prior. Had it not been found, it would've shot OUT of me like a bullet in the magnetic field of the MRI. Cool. #coolstorybro
They likely only use a resistor on that "PWM" line because the "PWM" signal from the controller is probably driven with an open-collector output, which means it switches between "pulled down to ground" vs "allowed to float" (it is never driven with a positive voltage at all).
Essentially, the transistor driving it already serves the purpose of the diode in that case.
Great video! The way my mind exploded when you casually marked up the circuit was the real boom this week! Thank you :)
0:53 contact surface area of just the arc vs the pads at the end of the board.
7:29 what happened to the BOOM in ElectroBOOM
It's just Electro 😢
I worked at a monitor repair facility. I wasn't too good at repairing part of things (the flyback transistor was no joke). But I did have one of these guns to clean the tube contacts and I was responsible for scan line alignments.
7:00 😮😮😮😮
Man I really like this guy! I have been watching him for over 3 years and he still he doesn't fail to impress
Who here is still waiting for the next Latity episode?
Me
Interesting video! I recently bought a device from China that can output any kind of voltage and ampere upto 32V from an input of 6V to 32V. I don't know much about electronics but I was able to charge a trimmer with it. I got an adapter set with basically all charging connectors in existance and connected a car lighter plug on the input. So now I can theoretically charge anything in my car. I hope nothing blows up......
6:00 old samsung? deam i'm getting old
1:41 i love the crunch then the cut off while doing cpr
I feel like a collab between you, BigClive, and AvE would be AWESOME.
Styropyro 🧟♂️
That's would be amazing
Also note the pancake style flat tesla coil: The coil is mounted right above an aluminum heatsink: since the coil is air-cored, The induced eddy current losses from the heatsink will decrease the output
1:36 The video start very well🤣
Unfortunately you cannot run everything on a battery pack. Battery packs need to activate the DC to DC switching inverter to increase 3.7 V from the battery to 5 V or above. The problem is that this inverter constantly draws power from the battery, even if nothing is connected to it on the other side. So the battery would run flat in a few days without even powering anything. That's why almost all battery packs have a sensor that will completely shut off the inverter unless a certain amount of current is drawn at the output port. The problem is that some devices draw so little current, that the battery packs shuts down the inverter even though there is a device connected to the output. E.g. if you run a Raspberry Pi on a battery pack and it's CPU goes idle, it will draw so little power that most battery packs simply shut off. I also have a radio controller with LCD screen that I can use to control certain house electronics and it also draws so little power, that it won't run from a battery pack (it will work for a few seconds when I connect it, then the battery pack shuts down the inverter again). You can prevent your battery pack from shutting down like this by adding a resistor between power and ground that ensures a certain amount of current is constantly drawn at the output port, but that will only make the battery run flat even faster than with the inverter being constantly powered alone and all power going through the resistor is totally wasted energy that only produces some heat.
Best channel on RUclips hands down. I don't give a damn about electricity or know anything about it , but i binge you and learn allot cause i like seeing you get shocked 😂 because usually when you are shocked it's usually something i would do that did it lol. just don't die medhi we love you!
5:56 Isn't it supposed to be a dc-dc converter? "Switching inverter" is usually a term for dc to ac switching supples and while they are topologically the same their control circuits are different
10:22 Ah yes, Gates of transformers
This video CHANGED MY LIFE!!,,,,,,
Taking stuff apart is always fun ❤ I wouldn't know half as much about electronics if I never took stuff apart. Definitely want to see this as a series!
I honestly don’t understand anything you’re saying Mehdi when you do your small “lectures” in your videos but I enjoy listening to you just as much as I love watching your videos.
The plug in of type C really blew my mind at 6:42
I love the idea of a bug killing handheld tesla coil personally. I really want one of those but a lot more powerful, to the point where it just roasts any fly i hit with it

I have had an overwhelming curiosity about everything in this crazy existence we all share for as long as I can remember. It’s the primary (pun intended) reason I watch your channel! That said, I have always freely shared what I know with others. It took a lot of aging before I realized how arrogant and annoying this can be. I’m jealous, and yet very thankful, you can monetize that which you enjoy, Mehdi! I know i will continue watching your channel for as long as I am able! 👍🏼 Thank You for sharing your knowledge! 😊
Same happens to me, I learned a lot of stuff from different topics because I like to learn stuff, so I always have something new to talk about and when I'm with other people usually happens two things; or they don't care and don't wanna hear what I wanna tell them or they're willing to hear but doesn't know what the hell am I talking about so it ends up being a one way conversation and I get bored for not having someone to bounce ideas with and the other person maybe it's interested but finds the info difficult to understand so they end up bored as well, so across the years I learned how to tune down my crazy man ramblings to a more regular level to engage with regular people or else I would probably be an introverted weirdo who doesn't talk to anyone xD
@@MrLind87 What did you just call me?! 🤣😂 Yes, I understand completely. I decided if I ever marry a pigeon, that is when I know I’ve gone nuts. The last guy who did that gave the world so much! He died completely alone. 😢
A few years ago, met some motorcycle friends at a local brewery. Was told where I should sit because “you’ll get along with those guys; they’re engineers.” 🤷🏻♂️ Asked them about their bikes. They replied that this was the first two-wheel Wednesday they’ve attended for the last 2 1/2 years. “We’re celebrating, actually. We just completed a project that took us away from hanging out.” I congratulated them and asked them about their project. They described their build and spoke about how close the tolerances were. I got all excited and said, “Wow! At those tolerances, you would have to worry about gravity during casting the…..” and on and on I went. Eventually, I stopped and told them it must feel great to get that done. “What kind of engineer are you?” “I’m not, I sell motorcycles.” They said I had just described all the obstacles they had to overcome to get it done. I confused them so much, they avoided me the rest of the night.
A friend’s husband came over to my dealership to take a look at a bike for himself. “I knew you would tell me the truth about riding.” Afterwards, we spent the next 2 1/2 hours talking about Nuclear power. He was some sorta specialist at the local nucular station. 🤷🏻♂️☺️👍🏼
Hi Medhi, your metal detector video was great. I think you should keep exploring generating sound from electromagnetic disturbances. Why not try making a Theremin?
