Not that that is very impressive I build this circuit wen I was 12 years old lol

Give this fellow points for showing his failures. I have been an experimenter just like him and taught myself a lot. Several years ago, about 45 to be exact, I was building a loud alarm tone generator and experimenting with different tones. Diodes, capacitors, transistors and such. Suddenly this thing started playing the local radio station very loud and clear. My wife said, gee you built a radio. Little did she know!

I used to tell my two boys growing up that when you mess up, you actually learn from those mistakes. They told me I should be a genius then. I am really glad to see you work through your problem. You will certainly remember that experience way better then had it work perfectly the first time. You now know what the problem was, and to not repeat it in the future. Bravo sir, Bravo.

You remind me of me 40 years ago. Although no internet. Radio shack was the only source for parts and kits. And alot of my chore $ went to another passion: baseball cards. I would scrounge old radio and crt tv parts and my Dad's old car batterries. ALOT of trial and error (like you, but that's how we learned). Had really no idea what I was doing, but it inspired me to what would become my lifelong career in radar and ion implantation engineering. One more thing..... I took it one step further. Instead of inanimate objects, bugs were often used in my experiments. I just wonder how a fly, or a grasshopper, or any other bug would react in the chamber, strapped to a paper clip? Not a diabolical experiment, but more of a curiosity thing back then. (Think mag glass on a sunny day and ants). You just brought back fond memories of how it all started with me. Thanks. You do have quite a bright future ahead, I'm sure. Keep up the good work Tanner!

People are often trapped in an MRI with fields up to 7 Tesla. It looks like you enjoy putting animals there. I think some big boys scientists decided to put humans inside a magnetic field instead of bugs. No harm is noticed. Caveat though. I remember the 45 Tesla world's most powerful magnet, people aren't allowed close to the thing. It can even destroy films at several feet away.

Thank you for the video, you're the first to actually explain how the MOSFETs start up the resonance in this circuit from what I've researched, appreciated.

If your teaching newbies your lesson is jiberish but I do appreciate your attempt.

This video gave me like an 80s garage lab style vibe Dunno But I really liked it This kid's goin places

I love that you post your tribulations with electronics. Most people only publish their finished works and never their trials and errors. Subbed!

I like your video. It is very humbling to show your fails. Keep up the good work. You will go far in life. Stay away from drugs and alcohol, they will ruin your life, learn from my fails on that matter.

brandy sigmon, as you said [reworded] - it's humbling to publicly recognize your fails. Maybe this isn't the first time but either way, through your comment you've just accomplished the same thing. Publicly recognizing a failed portion of your past. Trust me when I say it's absolutely never too late to "reboot" & start fresh. Does it mean you'd be getting started on things at an older age than SOME? Obviously it does. However, simply getting started on something truly fulfilling & productive to/for yourself, is much more than MANY, many people will ever do in the whole of their lives. Reason being the fact that it's not "easy" to do. It takes effort, & a majority of people don't want to invest that effort. Think about the stress & effort of times you were waiting in a grocery store parking lot for your connect to show up & when he does, it's an hour after he said it would be. Mentally tally all that time & energy, & consider what greatness you could accomplish, or knowledge you could acquire if you could convince yourself there's more reward in putting the same amount of energy into "starting fresh". Again, not easy, but if you look at someone "just getting started" on things (at an older age than some others) as being 10x stronger & more knowledgeable than the average person, then you have to realize that first going through recovery, staying with recovery & on top of it "getting started" on useful things makes that person 50x times stronger, with 50x more potential for great things than the average person. Maybe you know this already, but I wanted to comment just in case you thought otherwise. Trust me on it, I'm positive of this. Feel free to contact me or reply back if you do question what I'm saying, or just need a mental boost from someone else who gets it. :)

At significant scales, the induction heater should NOT be turned on with the load inside the coil--A larger metal mass can easily draw a current surge that is initially too high. I learned this one the hard way! Also, while on the subject, A slow rise power-on can destroy the heater--let the power come up to the steady state and then turn on with a switch. One more thing comes to mind: Once the unit is operating properly, the main power (variac or whatever) can be adjusted (raised or lowered). I hope this helps you or others. Your videos are among my favorite. Anything special /new planned for the future?

Anyone else sit back from their screen when he started counting down......? Having the humility to acknowledge your fails shows a strength of character ,far too many people these days seek to portray themselves as perfect.

This is definitely the best video about diy induction heaters on all of youtube!

I'm a Union electrician who has worked on many industrial jobs.I came across a holding tank in a foundry that raised the temperature of the metal by induction but also by frequency.Today they are common place along with inductive furnaces that use frequency.

I appreciate the realism here, including the mistakes and the lessons learned along the way. Awesome video man!

well done son, not so much your method but your tenacity to keep going on until you got it right. That's how people end up with Nobel prizes keep on keeping on little man

Smoke test. They say electronics run on smoke. If you let the smoke out they don't work anymore. Good video. I had been wanting to learn about that kind of circuit for my own aplication.

I love the youthful energy and tenacity! And burning stuff just for the sake of burning stuff reminds me of a much younger version of myself.

GREAT WORK! You can bet many other youtuber's jump straight to the successful outcome. But, YOU DID IT RIGHT! You learn, I learn, we all learn this way. ...reminds m\e of Thomas Edison and the light bulb.

Sweet! I greatly appreciate you keeping the learning process in the recording. I'm very hard on myself with my experiments & prototype projects (yes, even during circuitry experimentation & invention.. ridiculous, I know). Because of that fact I sometimes need reminding that the path to building knowledge/understanding of something "forwards, backwards, & inside out" is the process of finding the solutions for those problems encountered. The more failures, the more intimately we know everything about something. This makes us an extremely reliable source of knowledge, & brings us one step closer to being the Authority on a given subject. So it helps me to see others go through the proper process, & realize I'm not screwing up, I'm learning & I'm not the only one that has to do it. In other words, thanks for burning up some components! Lol Excellent video man :)

Frustration factor-! But he pitched right back in and figured out the problem. Thank you for sharing your video and experiment! I guess I'll have to plan electronics like tomatoes.

Tanner - Great video, bud! Very enjoyable. I’ve been an EE, for 32 years. It’s a very rewarding profession and a great hobby. At the speed that technology is advancing, it never gets boring. It’s nice to see younger people getting so interested in electronics. Our profession really needs some bright young people to take over for us. Thanks for making this video. Keep up the great work!

I have also learned about the designs is if the power supply tapers up to it's voltage, the circuit won't oscillate and just shorts frying components. In this case the solution is to turn on the power supply first and then connect the power to the circuit.

It is interesting to note, at about timestamp 14:35 that the only part of the doubled paperclip, ONLY the steel parallel to the coil's field heated significantly.There is much less induced (coupled) current if the conductor is perpendicular to the oscillating field.

this kit is awesome! he will make it very far in life, already has a masters in electrical engineering ,and hasn't even made it to collage yet

Good job figuring out that the ferrous coil is a no-go. Impressive knowledge.

The schematic analysis is what I like most for a newbie!!

*POP!* The sound and smell of learning.

Great job. Your going to learn a lot. My self have burnt up or destroyed a lot of electrical components years ago . Don't stop learning

I wish I could retain all the knowledge quicker or was taught about electronics a lot earlier. This guys pretty damn smart! I was a bit confused when he basically bridged the two prongs on the right transistor with the ground

Dammit, you did say ferrous metals. Thanks for sharing a great video.

It's great to see this young fellow build and test this device. Learn through mistakes and not give up. And in the end, success. Keep it up and you will go far in life.

Thats Great BUT i think a more technical way to test these circuits would be better as you did blow a lot of expensive MOSFET's during the testing process, i use a high power 12V lamp for this connected in series with the power supply to the circuit, if the circuit is working fine normally the lamp may have a faint glow BUT if somethings wrong with the circuit and its drawing far to large a Amps from the power supply or battery the lamp will light brightly and it will save your components from destruction, i am pleased you found a local component supplier to support your channel, BasicMicroUK would have loved to do it but it would not be practical because of where we are located, i hope our approach to you helped you get your new sponsor, all the best, Dave

Great comment about the 12V lamp. What you describe is essentially a PTC (positive temperature coefficient) circuit protector whose resistance increases dramatically once they reach a certain current threshold. I used to use the ones made by Raychem (now owned by another company) in my motor drive circuits, and I have seen actual light bulbs on the crossover circuit boards inside audio speakers to protect them from being fried by too much volume. Great job, Tanner. You have a bright future in electronic design ahead of you.

Good job on the project. And kudos on sticking with it and figuring out the problem. I think your next step should be to build a larger copper coil and covering it with pyroplaster then use a steel pot as an crucible so that you can use it to melt Lead or Gold by heating the ferrous pan. Lot of potential there.

Fantastic, thats how i started out when I was about 10 yr old, ( I am over 40 now) great work. really enjoyed it.

Awesome work. I love seeing these young smart minds doing their tries, tests, and succeses!

I like the way you explain things instead of just doing. This makes it easy to understand and learn. I'll hit the subscribe button now.

"It never works until you prove it can't not work." That's what I took away from workbench adventures much like this one!

Very nice demo. I like the cleanliness and no clutter presentation of your project. Good job!

More tips to make it better - keep the leads between power components as short and as thick as possible, coils should be made from low resistance non ferrous materials like copper, aluminium or silver if possible. High frequency coils also like to be made with equivalent thickness of thin wires in parallel rather one thick wire, due to the skin effect. Foils and pipes also work better than solid wires.

Whats blowing ut the mosfet is that the PowerSupply must reach its full voltage before connecting the circuit to it so a separate switch in between will fix that. What also is important is to start the circuit with an emty coil that will save you som capacitors.

It's great to see that risk of failure did not stop you or slow you down. However, a simple fuse, breaker or constant current supply would have kept your new component drawers fuller ;) Keep it up!

I don't know if you've seen The RadioMechanic's induction heater video. He went into great detail explaining why slow power supply rise times would blow the MOSFETs, but since you started getting better results when you changed to a copper induction coil possibly the problem was different in your case.

Hey, would you be able to tell me if I should use a 10 amp, 20 amp or a 30 amp power supply?

What power supply were you using? If it's a switch mode supply it ramps the voltage on startup and causes the circuit to latch, and dead shorts the mosfets. If you're not using a battery, it's best to add an extra switch to toggle once the power supply has stabilized.

You the man. Enjoyed your video. Are you all self taught? Here is an idea for you. I work in the medical field and I have been researching and reading on how to build a homemade EKG machine. At work we have to attach leads to the patient in order to obtain a signal which is then processed by the circuit board to obtain a wave form. My idea is to devise a smart lead attach it to the patient without wires and have the smart lead communicate with the circuit board via blue tooth or with a laser. I would welcome your ideas. RS

You make a great teacher with your enthusiasm and knowledge. Also very entertaining!

Nicely done. I like the failures being left in...we all make them. I have a melted spot on a proto board where I melted a 555. SMH. I blew a chunk out of an IC once, too. Smoke happens. I'd like to know how the freq is set (capacitor sizing across the load coil?) and what, if anything, sets or limits the output voltage/current. I'm a hack w electronics, my apologies if learned folks would know this info from looking @ the schematic.

I do like the t-shirt in the beginning, hope you will follow it. The world needs more hackers like you. Excellent work and review of the good, bad and ugly. Along with techie knowledge you show many other skills.

Here it is in Chinglish: It must be noted when using a switching power supply, because a high-power switching power supply generally has a slow-start function, that is, it slowly rises when the output voltage starts, and if the voltage rises to 10V, the induction heating circuit is turned on because If the voltage is not enough, the circuit will not vibrate, so that the two MOS tubes are turned on at the same time to burn the components. Therefore, it is necessary to connect the induction heating circuit after the switching power supply voltage is stable;

Thank you for showing us you fails! I also had lots of trouble with my ZVS and I used steel wire for my main coil as well..... I will try to change that out and see how it works Thumbs up from another young tinkerer :D

I appreciate your learning from your failures and not hiding them but putting them out for everyone to see the process of real learning. I would caution you greatly though, creating so much radiant heat inside a PVC pipe is likely to create some very toxic fumes. The kind that love to destroy young brain cells. Always be carefull of the chemicals in plastics and make good ventilation one of the more important parts of your workroom.

I never toasted so many transistors in my life. If something doesn't work, there is problem for that. No way just to replace components and trying to make it work. Thanks for fireworks, it was exciting.

Cool Project!! The reason you were unsuccessful using steel wire for your coil is because of the resistance of steel. Steel has a much higher resistance than copper as I'm sure you are aware. This added resistance in your tank circuit caused a slowing of the oscillation due to the increase in inductor charging time. This lower frequency meant that each individual MOSFET was on for an extended period of time. Since your coil was not wound around an iron core there was nothing to absorb the magnetic field and your coil reached it's maximum magnetic field quickly (aka Saturation). When a coil saturates, it no longer behaves like a coil and instead behaves like a wire (aka Dead Short). This caused a significant amount of current to flow through your MOSFETs. You may have experienced a similar outcome had you used aluminum wire. Keep experimenting and learning from your mistakes and your successes. Good Luck!!

FINALLY someone who explains how this works

Love it. Keep it up son, your future is very bright. BTW the no load current is reactive, with a phase angle near 90 degrees the power is minimal. When the nail is inserted the phase angle between the voltage and current gets closer to zero and so you get real power. So you see; the amount of current it draws, is only a part of the story.

This is a common problem with this push-pull inverter circuit. If the power supply voltage increases too slowly, both mosfets turn on together. The solution to this problem was invented back in the 1960s with bipolar transistor circuitry. A low power SCR from collector to base is triggered on with an avalanche diode, which saturates one transistor, starting the push pull cycle. The SCR is commutated by the saturated transistor.

It's a rare thing for people to show their failure, but this is the reality of actually building your own stuff, sometimes shit just does not work the way you hoped and it takes a good long while to figure out why that is.

Really excellent video. As others say, nice to see the fails as well as the success. Thanks for the ref. LCSC. Always good to have a reliable, quality supplier.

Thank you for showing the point to point wiring helps me to see it that way. Thanks for the root cause analysis on the ferrous work coil being the issue. Great video. Keep up the good work.

Best video on KZread explaining how the circuit and induction heating works. I also blew out more than one mosfet when I first built it. Good job.

I enjoyed watching your video on this induction heater, gave me a laugh, as it has brought up many memories of years past of myself. Please accept my next comment as a positive note. I do realize that you were in the testing phase or R&D phase of this project, but, for the future, as smart as you are, you are now ready to start putting great effort into building and assembling things in a cleaner fashion, even if they will possibly blow up. the more you make this effort a habit, the easier it will become. I'll check out a few more of your videos to see the latest efforts, to see if you have already started doing such. Trust me, designing and building your projects as clear & as clean as possible, pays off, for either trouble shooting or to impress your future boss, or to lead by example if you have employee's. Stay at it Boss.. You are already ahead of the curve.. Dru

I am building one of these based off of your instructable. I was amazed at how much this resembled the one from their. Then I realized that's your instructable also. Call me blind I guess.

Nice to see youth working with electronics. Have a Happy New Year fella with more to come. Keep up the good work too.

Here's an exploding battery just... because... stm32duino.com/viewtopic.php?f=3&t=22&p=1558#p1558 ... I must admit I'm much more careful if there is HT or mains voltage involved.. having said that, I did damn near blow myself across the room with a camera flash capacitor on one occasion, I was being so careful not to touch the wrong bit and handling it so gingerly that I dropped the camera, then grabbed it as it headed for the floor... the result was inevitable, lots of swearing ensued. Always be careful with capacitors, inductors and high voltages, they have a very nasty bite.

Very good and HONEST video. Nice to see how it would work if I made it.😩

A bit late but....You need to turn on the 12v with a switch in the 12v supply not the PSU. If as you were doing, you leave the PSU connected and then turn it on, volts rise relatively slowly and one mosfet turns hard on and stays that way until it goes bang. Intended for anyone thinking of building this stuff.

You are one hell of a smart kid. Great Video. Take my sub. Respect Brotha. Question: What does it do on thicker rods or bolts? Will it still get them red hot?

I learned from another youtube video that you can blow the mosfets by switching on with a slow rise, which blocks both gates at once. Or something. The switch-on has to be instantaneous.

Cool video. By the way, you should be pretty careful with PVC and very hot things. Lol. Burning PVC is some pretty toxic stuff.

Your welcome, mistakes are always the best way to learn. people don't learn by succeeding

a couple of suggestions, allways test for shorts before powering a circuit, especially if its a power one like this and bare copper is hanging around, also you could limit the current of the psu whether it is by using a resistor a current limited supply or an addon made for that purpose, that way if something inside is drawing too much current the voltage will fall and the chances the thing gets destroyed are lower

Don't forget that hysteresis of the metal.resists change in polarity. This causes heat. Residual polarity is over come with a change in polarity, causing heat. That's what read but not to sure of my understanding, just thought I would mention it.

this circuit seems similar to the simple oscillator used to blink LEDs, etc.. a couple of caps/transistors/resistors. interesting to see it beefed up.

I'm no expert at all. But I wanted to tell you a cloths hanger was the problem. Good stuff.

This is probably why induction heaters need to be snapped on sharply rather than ramped up.

At 2:13 you said that once the drain of the upper mosfet is at a positive potential, the drain of the bottom mosfet is at a negative potential. I’m having a hard time understanding why, if you could explain it to me that’d be awesome.

Thanks for the explanation of circuit's work

Very helpful video ! I'd like to deep in the theroy behind the circuit, how can we calculate the frequency of the current in the coil ? Do you know a source where i can this ?

Great job man, you are awesome, keep up the good work!

Dude keep it up! you are one smart dude! we need another Nobel Peace Prize winner! Plus I really want a flying car too 😂 👍 I got ten bucks that says you're the one that pulls it off when you're older!

Nice job, I wonder what happens when we make a conductive heater and set it at the right frequency for neodymium... Would It would be possible with the right equipment to suspend the molten dymium and cause it to rotate via magnetic fields.

Good enthusiasm but one should use a different procedure. At this stage, each component should be tested individually and it does not take so long to do that with resistors, Zeners, Mosfets. Listening and looking at the video what interested me most is the following. *At 05:16 the ground wire link connecting the two sources is too straight and it is too close to the drain and gate of one Mosfet. He should have sagged that link to ensure no other contact apart from the required one. * The Zener and the pull down 10K resistor is fine. * At O6:14 he says that he wants to solder that diode TOTHE SOURCE OF THE OPPOSITE MOSFET. I do not know if he did that, but he should have said that the opposite side of the pull-down diode should be connected to the DRAIN of the opposite MOSFET. It is Christmas Day 2020 so Merry Christmas and carry on with your enthusiasm but with a little bit more care as you build circuits and testing coponents.

@@TannerTech I could swear that, earlier in the video, you were apply power to the power supply input and letting it ramp up while connected to the circuit under test, rather than first turning on the power supply and letting it ramp up before applying the output to the circuit. In some cases with that type of circuit, it needs really quick rise time to start the oscillations. If not, it sometimes results in both FETs conducting at same time, and 'kaboom!'

+Tanner Tech The metal does not have to be ferromagnetic, everything conductive enough will work (it doesn't even have to be metal). That is because eddy currents are simply consequence of induction.
