  1. Sir.. I am an engineering student and i am doing a project on resonant coupled power transfer.. Can u help. Me with that.. Its a request

  2. Hello!
    Could you help me knowing more about how to ballast an high voltage transformer (MOT) to limit current and avoid circuit breaker to trip.
    I would like to use two mots to power up my sgtc.

    Thanks.

  3. Hey ElctroBOOM,
    Have you heard of Noise Canceling Headphones? If so, I was wondering if you had any idea’s how to make a Noise Canceling Machine out of them? For example, hooking the earphones up to a speaker somehow. Would they still cancel noise efficiently, or would we need to make modifications?

    I ask because my neighbours run a generator from 11 pm to 7 am, and it keeps me awake. I’d love to CRUSH that sound! (and them, but you can’t help with that… can you?) 🙂

    Thanks very much, Alex

    • Making an NC machine for a room is much harder than headphones because the noise cannot be isolated by speakers. Its very difficult to let the walls of your room (the space needs NC) to be covered completely by counter-vibrating speakers, and noise can still spread from uncovered areas, maybe cause an interfere and make the thing even worse. Its difficult, probably installing thicker walls can be more cheaper.
      NC is basically feedback->synthesis(processing)->re-amplify. there are even some circuit from second-handed NC earphones that is ready to use, once you have solved the problem isolating and counter-vibrating.
      Maybe its easier to cover the generator than the room as the source is much smaller. But this would still need lots of modifications.

  4. I don’t know the formula of the reaction with the copper 🙁 . But if you would like to see the formula of the rest of the reactions, it’s: 2NaCl + 4H2O –> Cl2 + 2H2 + +O2 2NaOH-
    At least I think that’s the formula.

  5. Hey Mehdi S. Can you do a video about Shock-gum toy to shock people with
    Also how does it work? 🙂

  6. hello,

    I like electronics and after saw your videos you made me laught a lot….thanks for that! and congratulations for your good videos.

    Kind regards!

  7. Hey, you know how everyone says that welding with 12v car batteries is the coolest thing ever? Well how many aa batteries would it take to weld with?

    • Avg. Car Battery: 12v, 70Ah
      Avg. AA Battery: 1.5v, 2500mAh

      – 2500mAh is 2.5 Ah (2500 / 1000)
      – 70 / 2.5 = 28. Therefore we need 28 AA batteries in parallel to get the same Ah as the car battery.

      – 12 / 1.5 = 8. Therefore we need 8 AA batteries in series to get the same voltage as the car battery

      Final answer: If my theory of needing the same voltage and amp hours is correct, then you would need… 28 batteries in parallel * 8 batteries in series, or 224 AA batteries.

  8. Absolutely wonderful, I’ve noticed a lot of people that are responding, are asking questions that are covered in you videos. The best part is; your just sharing observations and effects. DC does exactly what it does. And the “things” or “tools” utilized in sharing such information are readily avaliable (scavengable). In ANY professional job; (I belive) we are searching to expand our knowledge base, and by sharing, it gives us readers or watchers a “jump start” for exploring new possibility by both having not to figure the basics by trial and error. Just reaffirmation =) thank you for the valuable and easy, no nonsense, information that you present. It’s all there if your looking for it. Creativity rules! Thank you sir

  9. You have a great line of videos. You’re loads of fun! Question: If I have a piece of paper with flouresent ink on it, and I bring it near a tesla coil, what would you expect the outcome to be? I would think it would behave like the CFL lightbulb video. Will the electrons in the ink be excited and glow? Will the paper catch fire unless it was sanwiched in glass? Thanks!

  10. Hi,
    Could you do a video on how to make a dc-dc chopper converter or a buck-boost converter.
    many thanks…
    And nice videos by the way, they are really helpful, keep up the good work !!!

  12. I have a quick question about electrical engineering….
    So I was actually on this website last year, and I asked a question about how to step up DC Voltage, but now I have an Arduino I kinda figured out how on my own. I’m currently a junior in high school, and I was wondering specifically what kind of engineering you’re doing. (Building circuits without any micro controller)
    Also where did you learn how to do these projects? (College, Hobby, etc.)

    Thanks!

    • I have a masters in electronic engineering. So I learned these in school. In such programs you also learn to write software, firmware and use of micro controllers. But at the end of the day you do what you like most.

  13. Hey Mehdi,
    You’re levitating water video was educational (and hilarious or course). These days a big part of my job is researching and interviewing YouTubers. So, I must watch A LOT of YouTube. And channels like yours that are both funny but also have value to give the viewer, help me not go crazy. You’re awesome. Keep it up.

  14. hello Mr. Mehdi i enjoy your videos and think u r awesome. And I have a project that I am working on and i need some help and i would appreciate if u could help me… please if u have interest in helping me please reply to this and send me an email… and again i would appreciate it

    • Hi Grgur, I can answer simple questions, but I can’t help to complete a project. You can email me your questions and I’ll see if I can answer.

      • ok so i have watched your video on the taser but all i need is the spark because im making some kind of a canon with internal combustion and the question is how could i make the smaller version of the taser that it could work on a simple AA or AAA battery it doesn’t need to be so strong as the big one but just enough so it can make a spark that could ignite lets say butane gas in a chamber so actually i don’t need a taser but a spark igniter

        • Well if you need a manual igniter, just use a piezo igniter. They sell it for BBQs and such. You press a button and it creates a spark. No battery needed. You can also extract them from regular kitchen lighters.

          If you need electric igniter, you could also try and fine something like the following product:

          https://www.sparkfun.com/products/retired/11218

          I’m sure there are more out there.

          • I know everione told me that but i want to make the thing so it the whole thing is hand crafted id there a simple schematic similar to the one for your taser in your video

  15. hey mehdi.s first things first i love your videos but i would also like you to help me make the slayer circuit my 2n2222a transistor keeps heating and soon after blows up and iam not able to make the circuit work my circuit is a 12 volt circuit.should i buy a transistor of different number, please help . your videos are amazing and funny continue to upload more videos .

    • Make sure your primary winding direction is correct (flip the primary connections and try again). Otherwise there is not much to go wrong. Double check your connections.

  16. Hi Mehdi, i like your videos too much. But if u increase the turns in the secondary winding, the power transferring from the primary to the secondary will be affected or not??? ,Or we want to increase the primary turns also? , if there is a formula or relationship between primary, secondary and power transfer, then please reply………….

    • Hi Mohit,

      Increasing the secondary turns I don’t expect the power to get any higher, but the voltage will be high which means the arcs will go further, at lower current. If you also increase the primary turns the voltage will be reduced back again, but there should be more power transfer and coupling between primary and secondary should get larger.

      There are some calculators provided in onetesla.com website

      • Thank you for your prompt reply. This really help’s me. Hey, if u have a facebook account, so plz mention, i want to add u….

  17. Hi, Mehdi . I like your video so much, and i share it to my friend. And there are a lot of positive comments. Your vidoe is great , combine comedy and education. I think that good method to learn. Can i wish something for your next project ? if it’s okay, i want to learn about inverter from DC to AC. Because when i learn it from my friend book i couldn’t understand. So can you make next project to make inverter ? if it’s to much trouble for you it’s okay, but if you make it real i will very very very happy.

    PS: thank you mehdi, you teach me a lot with that video you upload. ヾ(*´∀`*)ノ
    and sory my english is not good. thx

  19. Hello, I’ve been one of your channel’s followers since the early dawn of your YouTube channel, and have to say: you deserve all the Kudos for doing all you do. It’s fun, entertaining and informative, all at the same time (and the stunts, they never get old).
    I don’t know a better (or even proper) way to contact you directly and ask about it, so I ought to try here: I’d like to ask you about the feasability and ROI on enhancing a motor vehicle’s electric storage by running supercapacitors along with the standard battery (or maybe even a smaller capacity one). My main motivation behind this is the fact that I notice both my car and motorcycle dimming the lights when spinning down (and having less efficient sparks – struggling to maintain the idle RPM even both being FI driven). Does this affect battery lifespan? Or would placing the supercaps just increase the drainage dramatically when left off for a while? Would it actually require a more complex circuitry, or would everything self-regulate if put in parallel? I’m beginning my years of Instrumentation, Control Systems and Robotics Engineering studies, and do hope to get to actually make/invent/discover something worthwhile, even if small – and I do take you as one of my examples, being crazy enough to run electricity through yourself fearlessly (although also knowledgeable enough to know the consequences of each current/voltage level) . If possible, could you contact me on the email supplied here? I promise you not to take much of your time, nor to be a nuisance.

    • I think I answered you somewhere else. A super capacitor would work and help the battery, but it is not very cheap or small. You should be able to get much better and smaller batteries nowadays though.

  20. Greetings from a telecommunications engineering student from Spain!

    Hey Mehdi… This may sound gay as f*** but I truly love you. You are one of the most interesting people I have had the pleasure to “meet” in my life. And, believe me, that means a lot. You’re not just a guy who apparently loves to get himself hurt with electricity. You’re one of those persons that make this a better world, a world full of laughter. As time goes on, I realize that happiness is the only thing this world tends to lack of.

    Keep doing what you do, and I wish you and your family happiness through these turbulent years. Health is the most important thing.

    PS: And please, don’t get yourself killed! Be careful.

  22. HI, I am a Electrical Engineering Student from Philippines and I am totally amazed at you I idolize you very much for such doing crazy things like that, I wish I had laboratory and instruments to try things you do hahaha xD ahhm.. by the way Can I ask where I can find a tutorial for designing an lightning arrester for atennas? or at least just how to know what kind of lightning arrester will be used thanks 🙂

  23. Hello Mehdi,

    I recently subscribed to your channel and I have to say, your videos are amazing! Not only are they very educational, but they completely hilarious. Ever time I watch the video when you touched the 120VAC I cry of laughter. You also got me interested in electrical engineering, which is amazing considering that I don’t even know what I want to major in. Hey who knows, we might make videos of us shocking each other with stun guns in the near future XD.

    Stay awesome,
    Papa-Sam Essuman

  24. Thank you for sharing your knowledge.
    I like the funny way you explain your ideas. Thus anyone can understand.
    Congratulations on your creativity.

  25. I own a small business, which repairs and calibrates electronics. For several years I have been recommending that my new hires closely follow a training video in which a singer named Bjork takes apart her television. Now that I have watched a few of your videos, I see that your presentations of electrical theory are far superior to her video. At no point, have I heard you describe the capacitors and rectifiers in your circuits as “looking like little houses where little people live”.

    Thank you for not being as silly as her.
    sincerely,
    beaglebreath

  26. When is the tesla coil gonna be done. I cant wait to see it. Thanks for all the youtube videos. Its a blast to watch them.I really liked the taser video when you kept getting shocked. I watched it arc to you so I know it was real.

  27. Hi Mehdi,
    Your videos are a great educational tool, both from the science teaching point of view and the safety aspects of what could go wrong.
    So often teachers take away the fun part of learning with dire warnings that are often out of proportion to the actual danger.
    Intelligent experimentation is a great way to learn.
    I especially liked the electric guitar video and the FULL BRIGE RECTIFIER (sorry for shouting)
    Keep up the good work !

  28. Hi, I just noticed that your engineering and sense of humor skills are not also attracting, but also exposes the brighter side of engineering! Thanks for the lessons you have given to me, and very much I have applied these. Since I have watched the Stun Gun video, I just kept laughing and learning. So, I have decided to subscribe and catch up with all your videos.You’re cool, bro. Keep practicing on your eyebrows! XD

    Sincerely,
    Rajzlra B., Science Journalist

  29. Hi,

    I’ve been watching your youtube channel for quite some time now. Just wanted to say I really enjoy your efforts to bring some excitement in teaching about the science of things electric. I hope you keep on exploring, being safe and having fun for you and your ElectroBoom fans!

  30. sir good eve… i just want to ask, can you make a DC power supply with a maximum power output of 110 volt DC, and with a potentiometer as a control… i would really appreciate it if you can have or give me a circuit of it… thanks sir… if possible i want to ask if you can give me a simple diagram, I’m a beginner electronic student… thanks if you can give me a circuit, if not It’s ok… GOD BLESS…

  31. Love your videos. I’m a chemist but had to take my fair share of circuits and electronics classes. I get a kick out of your videos. Watched them all the day I discovered you.

    Look forward to your future videos. Any hints on what your gonna be doing in future videos?

    Thanks and keep up the good work.

  32. Oh, Man! you’re a knockout! hahahaha been laughing all day because of your antics! I am not an engineer per se, but i have been the household electrician since i was 6 years old and the controlled chaos that you make look like accidents in your vids reminds me of my younger years. and oh, that profanity button beeping is hilarious! hahahahahaha reminds me of the tv shows on late night when i was in my teens. thank you so much for making the world a better place and sharing your ideas with everyone. i wish you all the luck, pal!

    P.S.
    Keep ’em coming!
    More ElectroBoom!!!

  33. Nice guy , made me laugh in my present times, i love what you are doing, like i did, more than a 9v bat, if it works then it should work right ? then it blows, congratulation on your journey keep at it 🙂

    Ps: been playing with electricity since 1990 ( i know am young but damn the worst thing is ive learned the same way that your joking about it)Sorry my english is not my native language.

    Pss: My Boy’s says hi
