In this video you will see how to make a simple wireless power transmitter and receiver.
For this project you need enamelled copper wire 0.4-0.6 mm, 2N2222A transister, 27k resistor, 9v battery and connector.
Follow instructions in this video and you can build your own wireless power transmission.
If you like this video don't forget to subscibe :)
Ironic how much wire it has.
Tragedic how idiot you are.
Ayy that's not nice! The more coils the more power so if he could do more it could be even better effect

You don't get the joke, do you ?
it's always hilarious seeing someone get completely triggered over a simple comment XD
lol
Amazing you inspire me so much
Mr. Experiment yes
Mr. Experiment i love this channel
It's nice to hear guys
The Q Where are you from ?
Mr. Experiment you are right
I made it for school project and it really works .The cost for making it is very less.
How many voltage battery you use
9 voltage battery
Bhai contact no share karo mere project ke saath issues hai
I can't
The cost is around 60-70 rs
What if i use a non insulated copper wire while making the coils
To those wondering, yes this really works. It took me a while to troubleshoot it (it didn't work right off, you'll see why) but I will say you absolutely need the 1k resistor. In another DIY article I read stated that the resistor will reduce the power and help the longevity of the LED. My LEDs are rated higher so I figured I didn't need it. Coil wouldn't work until I added it. Now I get to move forward with my project! Thanks for the tutorial!
I am interested in hearing more about your project Brandon..
Amazing, im very glad about this information, thanks a lot brandon, my project is totally work because of you
Hey I am using a 18 gauge wire how much resistor and what transmitter should I use for it to work
@@hazeliora9528it's too thick, try using 28 to 32 gauge
1k resistor or 27k? I dont understand
This is basically an air spaced power transformer inducing current from the primary to the seconary coil similar to how a wireless phone charger works
Pretty simple and electronically very cool! If you're wondering how it works, it's like a "reed oscillator", but with a transistor, not a relay. A coil can't generate large fields without an oscillating voltage (like AC), but he's using direct current from a 9v battery, what gives?! Well, coils are inductors and when you pair that with the resistor/transistor magic happens. The transistor is the key here, it's acting as a gate using the feedback from the inductors building voltage, but that feedback isn't immediate, it takes time for the voltage inside the coil loop to build strong enough to turn "off" the transistor gate. Then the voltage collapses, and the gate opens agian and the cycle starts all over again. So it oscillates! The receiving coil connected to the LED is capturing current from the power-sides building/collapsing magnetic field. Try this with more/fewer loops on one or the other side and measure the voltage (hint transformer). To learn more look up 'feedback oscillator' or 'Colpitts oscillator'. This is also what's makes the "switch" in the switched-mode power supply or DC-DC converter.
Can you please tell me what is frequency of this circuit or how to calculate that?
thanks, because this video appears to be fraud without your seemingly legitimate explanation which i will research. thank you
well, i researched "colpitts oscillator" as you suggested, abd that turns dc into ac also using capacitors, none if which are applicable to this video. you are a fraud and so is this video thumbs down.
For those of you who want to try to build this I can confirm that it works just fine with the parts listed and for the information that is not precisely described, I created coils of a diameter of 49mm (basically I didn't have a thin style coke can and guessed at around 5cm) I found a tube of silicon gap filler used in a caulking gun was 4.9cm so I went ahead with that. I used the copper wire as described in 0.4mm following the number of turns and orienting the ends opposite each other and the central loop at 90' to those. When I tried the experiment with 0.63mm wire I did not have success. But with the components listed, 0.4mm wire at approx 5cm diameter it worked beautifully! Good luck! And thanks The Q for a really satisfying project I did with a student of mine.
rating of bulb?
Thanks for this. I just tried it but it didn't work. I think my coil was too thick. Could that have effected it?
Will Parker PLZZ again explain it...
Actually, I m going to perform it..suggest me the wire diameter and thickness...which I use to perform this...
I tried this 4 times, it's not working
I would like to share some tips....
At first mine wasn't working and the transistor was heating
Then I removed the resistor.
And interchanged the connections of

It started working.!!!!😊
Ps. You can use as many windings and
Size of the coil.....
Comment for furthur suggestions and questions...
Thanks a lot
Mine started working ❤❤

Umm..
or perhaps reduce resistance, remove transistor and add a capacitor. tune both coils to center frequency to have a little more power at the receiver, as well as the range. P.S. resonant scheme works for AC sources
What are the number of this Cepesitor
amazing, i hope that you make a tesla coil in next video :)
(Pardon my English 🙂) Can anyone explain me how is this working as an oscillator as there is no capacitor used above. How ac power is being produced?
You just need a changing magnetic field to induce a voltage on the other loop. The transistor is turning on and off rapidly based on the feedback to its gate, which produces a changing magnetic field. This is obviously a flawed circuit, since it's not using an RC oscillator or H-bridge to create an AC signal, so it's very limited in the range and power it can produce. I'd look elsewhere.
@@masteranimation2008 Thank you!
it is known as mutual inductance. when current flows through the coil in generates a magnetic field which passes though the second coil thus inducing a emf and a current in that coil. This is based on faradays law and lenz law
A fake video. Because after electromagnetic induction, on receiving side, AC current is obtained. And LEDs cannot operate at AC voltage at all.
Actually, it's not fake becuz even if the output is AC and LEDs work with DC, the LED will light up from the positive half of the AC wave
@@neckslicer yaahh you are right....that's why the LED light is glowing not properly due to the half cycle
@@newcreation6532 yea 👌
LED is light emitting diode. A diode only work on DC. First, both of you go to Google and clear your concepts.
@@DrownedAmazon why don't *you* do that? it's not like I'm making up this information or something
I know I'm right. I don't mean any offense, but please check your information before blaming someone with information that might be incorrect and/or inaccurate.
This based on Electromagnetic Induction. When we change position of coil the magnetic flux the changes and induces emf and from Maxwell theory, change in electric field produces magnetic field . And also applied source is DC so electric field constant but changing position of another coil flux changes current induced.
hello! i'm a mere student and i don't understand something here. Why is there no need for a magnet? Our teacher's demonstration had a magnet on the circuit. Can you please explain? I would greatly appreciate it 😃
@@thisgirlpurpleyou3334 ok
@@thisgirlpurpleyou3334 actually there is flux linked with coil which carry electric current. As we know current carrying charges produces electric field. As per sir Maxwell, change in the electric field produces a magnetic field. This magnetic field opposes cause that induces magnet field so,a current produce in opposite drn to oppose this cause. Due to this a current produce in Circuit.
WHY ARE THESE SO SATISFYING TO WATCH? COME ON
It's works! I use bc547 transistor (NPN) and 1k resistor. When I use 10k resistor it didn't work but when I use 1k resistor it's works! ( 27k or 10k it's too much resist)
Didn't cause ur 9v battery to overheat ?
Doesn't work for me =(
What is the volt of the battery you ised
@@jazer992 9 volt
@@dannyboy132100 No
I hope it's not fake. I'm sick of watching fake videos
No one asked you and by the way if you are saying this,it means that you don't know science... got it .....
If your sick,go and consult doctors... what are we supposed to do... like why do you comment
Why did u take 30 turns of enamelled copper wire??..
wireless power transmission- first ingredient: copper wire
LMAO
I have a charging pad and I made a coil and my led goes: blink, dim blink, blink, dim blink
you can add a half bridge rectifier (or even better, a full bridge)plus a capacitor before the led and it will stays on constantly.but make sure to connect the + and - legs of led correctly to rectifer or else it may fry or even explode.
The led is pretty dark. This is because you don't use the resonance frequency of the coils. You also should use capacitors at the end of the coils. GreatScott! has a good video about wireless charging. I definitely recommed you.
You use induction like electric hot plates you do a bigger one like a carpets or if you have time a entire room sorry for my English I am french
Like my comment for he can see hit plz that's important
moctar Your English is how badly I understand French
Bonjour
_Bonjour_
Saluté
:)
I used a 1.5v double a and it still worked, awesome video.
How many coils did you do?
You need two capacitors to cancel out the reactance of the coil.
explain plz
No only one
Of what number and Thier position
please for the love of god, clean your iron between solders.... just killing me here...
Mine is dirty by solder, plastic and who know what
my 2n2222a is getting very hot! What can I do about it?
Can I use any other resistor like 22k or 47k or should it be only 27k because I can't find one in my area
go for lower not higher.
Tesla tower model like connections... Yes it is real
Can i use 2N3904H331 transistor
Allow me to comment. This your design, the way you built it, will cause the battery to drain quickly and will not be the LED that will drain it, it will be the transistor. For you to have a 90% efficiency and more amperage I suggest you use a BD139 transistor with 2 ceramic capacitors (same values) and 1 diode. One of the capacitors goes into the collector of the bd139 and the other capacitor goes into the receiver along with the diode to do the polarization. I can charge AA batteries and also those larger ones that comes in laptops. Of course the charge is slow but this is even good as they extend the useful life of these batteries. 👍😆
Awesome
Transistor npn or pnp?????
Does it work with a 22k resistor?
HRITIK
Please tell me what is resistor
Not work sir
I did exactly like this but doesn't work
Are you using ac? It has to be alternating current direct does not work you can google the specifics of how that works. Hope this helped!
I am a indian
Transformer doesnt work on dc....
Tried it. Didn't work. Wondering why?
At first I used just copper wire, then I tried it with enamel copper wire. (I swear I connected everything correctly)
Does the diameter of the coil matter? Mine looked a little thicker than yours.
because it 's DC circuit, the wireless transmitter should be AC circuit.
You do to much cool stuff it's amazing
Thanks bro helped me to complete my Holiday assignment.
Thank you very much😀😀😀😀😅.nice video👍👍👍
Can i use solar panel instead of battery and mobile (through OTG Cable) instead of LED.
No it won't work try out the same thing with 4 rechargeable batteries taken in series, a 44n transistor and a diode bridge in receiving coil
Boom your wireless power bank is ready
That's some shitty soldering.
My dear frinds its fake dont waste time by make this useless thing
electromagnetism!!👍
The soldering was amazing! It looks like how I fixed my fan controller in my 1988 Honda Accord.
may I use 22k resister . please reply

in your next video can you teach me haw to make a refrigerator ! that would be cool and cool for your millions if people who would watch it !
Get some peltier devices and a few heat sinks boom refrigerator
Now, how to extend the range of it.
By increasing linkage flux ..
@@azaykumar8792 how to increase linkage flux
By increasing number of turns and current
Actually it uses more wires than a not wireless...
Benjámin Péter but it gives the idea of wireless power, so you can understand and use it in different ways :)
Benjámin Péter gtfo
Actually, it uses more energy than a not wireless.
good for you
Isnt it strange that we add an "less" in front of wire but use "not" in order to show it has a wire. "Not wireless".
I build this project but my reciver side is not workings. How check it out put comes from input side
If mutual inductance works on the principle of EMI then by using DC source how the power is transmitted to LED.
So, it's basically an oscillator and a transformer (in which the 2 coils are not connected)
This is a really great project for groundschool wow
Legit, IDK what Im doing wrong. I wired everything up as it needs to be, I cant get anything to work. I have a coil 15 turns, 15 turns the reciver is 15, Ive tried capacitors, with and without a resistor, with and without transistor used 30v of power...nothing.
Excuse me sir , why we using a transistor hare , cant we maks it without transistor ? ,
I mean simple inductor wire with two points directly connected to the battery , it would be something like transformer but without irone core , cant we do this , or we use transistor cause there is any matter of frequency there
Will it work if I used 30 turns at primary and 100 turns at secondary?
hmmm
ut is basically a transformer without core.
just curious as too why the resistor and what effect would a stronger or weaker resistor have on the output?
If the value of the resistor decreases, the brightness of the led shall increase, it is the vice versa if you increase the value
Hey can I use any transistor like that?plz reply.
Increase range?
Loss factor?
Thanks!
Don't have a lot and have not been able 😔😥😥😥😥😔😥 right right 😒😉😒 really 😔😥😥😕😕😔😔😕😕😔 eydgei yr

Not a drop to drink...
(Completely irrelevant comment. Ignore me hehe)
How can you calculate the power transmitted and received for this please?
if i roll the coil more than 30 turns, can the range be farther?
Electric flux.....
Based on the principal of mutual induction
U need ac for wireless transmission .....
I think this is fake...
No you don't XD
User TCQ the transistor does not convert it from DC to AC because their no outer signal to base to output a ac waveform
If u still have any doubt check this-- ruclips.net/video/TQwGjhwPEik/видео.html
This has been confirmed as real
The transistor is there to create an alternating current.
The transistor its used as an amplifier. That's it's main role. It amplifies signals relative to voltage on Base pin. That's why it has a resistor on Base.
Will it work without transistor and the power source is a 220V ac ?
how much voltage goes through?9v to ?v
I repeated it, around 5v
This is more of an air-cored transformer but nice presentation.
So what do the transistor and resistor do here exactly?
The lamp shines in the file because of the mutual induction phenomenon
اطيتك تعليق بالعربي اني هم عراقي
can you tell me this copper wire gauge number and transistor model name
MY transistor get heated up when I supply it 9v, and after some time LED stops working or get dims.... plzz help as sooon as possible pllzzz
Choudhary Divya Dev the transistor is either getting too much power/voltage or its not properly grounded. Make sure your ground side is on the right side of the transistor “base, emitter, or collector, depending on your design.” The LED is probably not getting a lot of current and that can be due to the transistor problem. The LED is just a load, only thing it needs is current going through it. If it dims, not enough current, if its dimming and turning off, it could be a connection issue. If its not turning on at all, then you could of ran too much current through it and blew the LED
Can i use a potentiometer because i do not have that resistor?
🙅🙅🙅kam nahi kiya
Should be called watch me make instead of how to make. You explained nothing
is it possible to do this with a small ring inside a bigger ring? (im thinking of putting a project together where the device gets charged by being put upright in a base)
Its in theory, mini transformator, and there is loot of power lost in medium (air)
hey im a newbie to all of this but isnt this possible only with AC and not with DC, did he somehow convert the DC to AC or somethin with the transistor n stuff, again im a newbie so pardon me if i have named any component wrong
Hook this up to a diamond battery and you’ll have 25 years of wireless power

Fake
This is excellent. Can you please tell me what different mediums there emf can pass through. Like, will it pass through a wall?
I have a problem. When i try to light the led, it works for a second and then i have to move the position of the tranzistor and the copper wire from the + pole. Any suggestions?
Is it because I used tape that izolates the current to keep the copper wires in their shape?
I have used 1k ohm resistor and it worked 10 times better than you.
what is we use dc buzzer instead of LED
What is the Principle on which it is working????
you can clip to make a charger for mobile phone of this so-called Wireless
It is not efficient enough
Now make it on the scale of the pyramids of giza so you and your friends can have 100% free long distance charging
using a tesla coil would be a much more efficent choise
Sir my model is not working. Only transistor is heating up. Can u tell me the problem
Garvit mukhija try using a better transsitor
Yes sir
Not wireless it's mutual induction
