DIY induction heater

[kargaroc386]

Was that igniting the air around it? :O

[glockfan112]

how do you make this? i am 14 and on a $100 dollar budget so please keep it simple and relitivly cheap

[muh1h1]

doesn't the heat from the bolt melt/burn the insolation of the coil making a shorcurkit?

[ShoestringScientist]

No, no, the point missed was --this is a DIY site -- not youtube. How do we do what you did? How do we do it ourselves?

[massivemak]

put your dick in there.

[hardstyle905]

@massivemak OK. No problem. Wouldn't even get warm

[uber2ber]

series resonant circuit, capacitor in series with coil, connect one wire from power to one side capacitor (-), other side capacitor to one side of coil, other side of coil to other other power wire (+), buzzing sound and metal plate probably microwave oven power supply, .33 uF 2kV DC capacitor, resonant frequency depends on uH of coil - and don't be sticking your stupid fingers or anything else in the live wiring

[Dennys787]

i dare u touch it.I.fucking.dare.you

[jeetendrag10acc2]

Even in jewellery this could be useful,some kind of zone forging.

[TheDextersd]

DIY(Do It Yourself) now teach us how to Do It

[jeetendrag10acc2]

dude,this could be a very useful little gadget.

[mask477]

Dude can you please post the schematic or give me the link to one .. i would be really greatful. Thanks.

[jajaid6]

this would come in handy for freeing rusted bolts.can you give me instructions on how to make this?

[SMBfan1981]

how do you make these? I'm really interested in forging stuff and so far this looks like the fastest way to heat up the metal. Please send me instructions.

[eloid777]

where can i get schematic plan for this induction heater

[pietzeekoe]

TUTORIAL NOW!!!

[leonardo1480]

Would really love to see a video on how one of these things is set-up and all the other details like what voltage and other components are used

[fuelban]

What is the power source, 240v AC, Or / DC 12v ?

Thom.

[matias676]

well this was real informative

[halfmumi]

i have an old kettle with ind. heathing mechanism inside,does anyone knows that i can DIY it into a ind. heater??

[cyberlord64]

Damn!!! What's the wattage consumption?

[davidj121]

looks safe lol

[venomx2]

@100silverpizza no.

[TF141Afterburner]

But Will it Blend?, That is the Question..

[jktuno]

Its so pretty. i want to touch it.

[sircoolgandalf]

this is a great device.

I will pour out al metal rings. I need a furnace.

can you send me a wiring diagram.

or a description as I can reconstruct the device.

so I can build me a small furnace.

that would be very nice.

thank you

ralph

[trapingman]

how is that flimsy little coil not melting as well?

[frollard]

@trapingman because it's not designed to - its not a resistive heater, its an inductive heater - it works like a microwave oven for whatever is inside - in this case it's tuned to heat up that metal nut :D

[trapingman]

@frollard I know that and i also know that putting several hundred watts through one flimsy little wire tends to melt the wire!

[frollard]

@trapingman True; in this case however that's HUGE gauge wire. Think a 1500 watt space heater on a standard household plug - that is smaller wire than it being used here (with consideration for multistrand v. single core)

[trapingman]

@frollard well the gauge of bolt there is WAY HUGER and its turned white by your incomprehensibly thin coil

bolt = about 20 times thicker than coil coil= warm bolt = mini-sun

[frollard]

@trapingman You're missing the point. THE WIRE IS NOT A RESISTIVE HEAT ELEMENT! When you plug a heater in the wall, the extension cord doesn't get blazingly hot, the heating element does. In this case, think of the coil as that wire - transmits thousands of watts into a MAGNETIC field that metaphorically pisses the molecules of the bolt off with eddy currents until they get hot. (check wikipedia on inductive heating). The field doesn't nearly affect the coil as much = little heat in coil.

[trapingman]

@frollard i've burnt insulation off of wire that thickness with a 6 VOLT BATTERY! (it blew up after 3 seconds)

YOU are missing the point

[Renegade30]

@trapingman That would probably be because you are overdrawing the battery, if you set up enough resistors in the circuit the battery wouldnt blow up.

[MrStemkilla]

@trapingman dude it doesn't matter if he burns out the wire he will replace it with a lower gauge wire its 4 feet of wire it docent matter

[ParaglidingManiac]

How many volts is that?

[BasshuterZ]

What is this? Where i can buy it?

PLEASE REPLY

[darknidevle89]

How do you make this induction heater i want to build one but dont know how. Can you post a video on how to make one or give the schematic

[rfengr]

yaaaaay red gas !!!

[youtubsuxfv]

What is this for? Does it generate electricity or what it is for?

[Art4Law]

@youtubsuxfv If you don't know or Don't have the brains to figure a few things or uses yourself THEN... YOU DON'T NEED TO ASK.

[johnlvs2run]

Can you design an induction water heater?

[Mato0092]

@johnlvs2run That's the most stupid thing I have ever read.

[johnlvs2run]

@Mato0092 Electric water heaters are more efficient, because gas water heaters lose most of their heat up the chimney. Besides that, you have the noxious pre and post burn fumes in the house.

Induction heaters are the most efficient type of electric heating. I use an induction cooker and it's much faster and less expensive than gas, or any other type of electric. And so, I would like to convert my water heater to induction heating.

[luthmhor]

Do you know of anyone who would sell a home made induction heater? I'm really interested in getting one, but the ones online are for professional use and are minimum 2500 dollars. I'm only willing to spend 200-500$ really :(

[cassiavc]

Is it expensive?

[ryobie1]

Am I wrong when I say DIY is suppose to show you how to do it yourself?

This shows nothing but another induction heater.

[Art4Law]

@ryobie1 Yeah bc HE DID IT HIMSELF!

[Mato0092]

@ryobie1 DIY means "Do It Yourself". It doesn't have to mean he has to show how he did it. But you can find a lot of schematcs using google, try it ;)

[palefalco]

@Mato0092 --- This is DIM induction heater

[palefalco]

 --- This is DIM induction heater

[sworteu]

@ryobie1 i think this DIY (in this vid) means Did It mYself

[cooladas]

can something like this create thrust?

[shaneo0306]

@cooladas lol noob.

[stdavross666]

@cooladas no, it only heats metal objects place inside the coil

[ImMichaelTaylor]

@cooladas As a heat source for vaporising fluid maybe. E.g. to heat a conductive pipe with a liquid in it, which could produce a jet of vapor.

[soverato3]

can it melt aluminium???

[srm13560]

@soverato3 it heats any metal, since it's all about eletro-magnetic field.

[Nordashi]

niceee colorz xD

[mysteryteacher9]

sweet

[panzuman]

where did you get your circuit

[vauIt13]

no on induction stove, you need iron/magnetic responsive materials to make the metal inselt heatup and not the stove in itself.

[droopfrogg]

ghettofabulous

[100msw]

looks like the enamel on the wire is burning

[Dawid4Real]

just asking. . . if you make that bigger can you like. . . cook food super fast?

[WascMeister]

google it, induction stove has been around for some time

[Earthbound64]

no

they would burn!

DONT think logocial für cooking!!!

[numair23]

lolol if its conductive food

[definca]

Sixty Four Comments........and not a single one of you Einsteins have a clue. This WAS a cool project and experiment right up to the point at the end when the CADMIUM PLATED HEX NUT TURNS THE CADMIUM PLATING INTO. guess what?.......HIGHLY TOXIC GAS FUMES. Did you see that nice brown smoke from those sparks as the CAD PLATING VAPORIZED AND CONTAMINATED YOU ENTIRE AREA AN UNLESS YOU WERE WEARING A RESPIRATOR AND TOOK A SHOWER AND WASHED YOUR CLOTHES YOU JUST GOT HEAVY METAL POISONING. nice!

[geurgeury]

but dude he did it for the lulz

[100msw]

Looks more like enamel on the wire burning

[goose2goose2]

@definca yawn...happens everytime a welder hits a galvanized bolt...

we're all stlll here...and the sky is firmly in place!

[definca]

@goose2goose2

Goose, get it right, few standard bolts are galvanized, most are cadmium plated.

Why breathe a poison? Why inhale a heavy metal toxin? Seen any of the new equip welders are now using? They are not breathing fumes any more. do you know why?

hmmmmmmmmm........lets see...........????????

many dangers take time to show up the harm you have done to your body.

[tygertung]

@definca

Nah they havn't been cadnium plating bolts or nuts for many years due to the high toxicity of cadnium. They tend to only use cadnium plating on aircraft hardware. Most hardware for general use will be zinc plated or galvanised.

[Ginrai89]

How to build this thing ??

[TheTruthPusher]

Not as fast as thermite, just ask Silverstein.

[JOEYtheBrenton]

how can i make one.

[Roobert33]

Beautiful.......5*****

[Streamtronics]

Your coil burned xD

[joharasaluki]

I would really like to get my hands on something like this to melt non-ferrous metals for casting.

[SinisterLegion]

first thing that came to my mind was to forge custom knives with this.

[tarjr94]

im surprised there aren't any videos like that, using an induction heater to forge sounds really convenient

[EchosFromaBlankMind]

@tarjr94 Yes, induction heating is also used for forging metals when only a small area needs to be heated and worked.

[khaostim666]

i used to use a simular thing to this when i worked in a factory, to solder nuts onto big telecoms cables :P

[GrandpaTD]

Where did you get that heater

[AgentCROCODILE]

For the tank cap is an induction motor starter capacitor OK to use?

[shehabtex]

h f with enough cooling syste and timer will produce the same result remember spot welding method

[jemmismagic]

how many volts did you use

[randomvideowatcher]

That guy must be in pain....He's melting his nuts

[alexsgarage]

I am building an induction heater using Powerlabs flyback driver ( Scaled up of course ).  What is the voltage across the coil?

[bboppkat]

someone show me the setup to this!!!!!

[WpA09]

hey does anyone have the schematics for something like this. would really appreciate it cuz i want one :D

[PepperShkr]

Its vodoo!!

My guess - if you take a HV power supply use for a neon sign and put thick gauge coil at the end.

It's just a guess - Try at your own risk.

[spinctah]

guess again

[ngdbud318]

Induction heaters operate at high frequency, 5-15 Mhz as memory serves. A neon sign transformer will operate at the standard 60hz like the power outlet you plug into. For us "Yanks" anyways. europeans would be 50 hz

[TheGeek1028]

Voltage, current, frequency?

[moniker127]

Holy crap.

[Gabriel9917]

can u post a schematic of the circuit please ?

[Roobert33]

Please LaR, could  you explain me how to build a DIY induction heater? I have never been able to get information aesaudienti by other users. If you are not sorry, could you help me? THANKS ...... :))

[grimcat27]

how did you make that I want to use one as a forge. I need an instructable on it.

[suupertramp]

wow, thats a clever idea to use it as a forge! i might just do the same. thanks!

[zimtower]

that looks like a ballast

[jupy921]

Excellent!

[ve2zzz]

DIY ???? Where's the power oscillator ?

Give us at least, the voltage/frequency/waveform/cur­rent !

[freefromgas]

I am wondering if you could use this induction and replace the elec. coils in a home furnace by heating a heavy bar of metal and controling its temp by a thermostat, and a fan blowing across it which would drop the temp quite a bit..what do you think..mack

[DrakeDorosh]

My Grandad worked for the electric company as an engineer. He used to boast that electrical heaters were very nearly 100% efficient. I think he was just talking about the conversion to heat in a resistance heater (electric space heater). The benefit of induction is in getting heat into a metal object. Your electric furnace is as efficient as it can be.

[thisismikeyy]

COOL

[kazuza9]

hi, great work u got. Is it possible to get a full instruction on such a system to teach students... how did u get the hi frequency and how much voltage??????? thxxxx

would u mail it?

[Fenristhebbw]

:O

...what?...

This really doesn's seem to be worth that type of outburst.

[ford65falcon]

How simple is this to make. can u send me some kind of instructions to construct such an induction heater?

[kurisu925]

It is basically an electromagnetic coil made of thick wire with a very high amount of AC power running through it at a very high frequency

[Deadzo]

You'd only be baking the rat; like when you cook meat in foil in coals.

Plus if it's aluminum foil it wouldn't work at all.

[holymonkey3]

won't work for a rat. it has to be metal. if you covered the rat in tinfoil, then it would work.

[darkpersonhi]

cook a hotdog in 2 seconds :)

[pitbike2006]

douse this work like an electric grill

[giedriusonline]

no

its more like microwave

this coil use magnetic field to heat metal

[pitbike2006]

ow ok thanks like a super powerfull microwave

[Prometheus203]

An electric grill usually uses an inductive heating element, for all intents and purposes this is exactly like that. No microwaves here.

[BasementBen]

Does high frequency, high power induce current into the body? Isnt it like standing near a cut open microwave?

Thanks for the video!

[Prometheus203]

No. An induction coil generates a rapidly changing AC magnetic field between 5-500 Khz at high current which causes heating in conductive objects. This does no work on the same priciple or at the frequencies of a microwave oven. Think of this as an electromagnet that changes poles 5-500 thousand times a second.

[fdoca]

Thank You, Is this more economic then a microwave? or infra heat? Regards

[Prometheus203]

Microwaves ovens cause heating by vibrating water molecules at high frequency. Metal objects exposed to microwaves usually act as an antenna, causing the microwaves to induce a high voltage charge in the object, infrared energy is generally reflected by metal. I don't think you can really even compare any of these, but if your intention was to heat a piece of metal this would probably be the safest and most efficient way to do so.

[jcrowner1]

Can anyone tell me how to make one. Does anyone have diagrams or plans? I want one for a knife making forge. The technology seems really clean and efficient...Thanks

[Prometheus203]

This should be fairly simple for you to construct, depending on the power you require. Basically you need copper, you could buy a grounding rod from home depot in the electrical section... Then you need a high current AC power supply which can supply the frequencies required. Anywhere from 40-135 Khz at 50 - 150 Amps should be suffient to heat anything you have. If your usings it continuously cooling maybe required for the coil.

[pitbike2006]

so its a sort of super heating magnet thing lol

[fireball471]

Anyone know where to find a set of plans?

Eric

[arande3]

Would it be possible to increase the power huge amounts with multiple transformers or not?

[ewigkase]

coll video I was wondering thought could you show how you have it set up? thanks for the video 5*****

[98209276]

man that was good im building one too but much bigger

[kynaniska83]

Cool! What is the maximum power of your inverter?

[LaRdArms]

The maximum safe input power is about 10A with 200V buss voltage, but i have blown the fuse to the 10A 230V outlet without damaging the inverter.

[rodripajaro]

Hey whic frequency are you using? And current?

[LaRdArms]

In the video i think it is about 200khz and 100v 7A.

I will post a video with my new setup soon.

[rovinghermit]

you have to give us some stats on how you made this, parts, etc.

[LaRdArms]

I used a PLL driver an H-bridge from my solid-state Tesla coil. The H-bridge is connected to the primary of a ferrite transformer with a 0,66uF capacitor in series.
