i've just finish making the same, instead of 5 volt i'm using 12 volt, its working man..nice job
Is it really work?
Please give me your watssapp no.
I am a science teacher i have already make this but it is not working.. please help me and my students.
God bless you in advance
Can I ask what's the size of wire use sorry I'm new in this just need info thank you.. just wanna try🙇
I also want to do it. But don´t know if it´s true...
@@LAXMANSINGH-rr9pg even for me it not working. i am gonna work on this ua-cam.com/video/AWhuu9TwMLM/v-deo.html
And that's how you make electric stove .
To cook your phones 😂😂
How about the 11 seconds.. you still need it?
🤣🤣🤣
Yeah.. if he hadn't use metal between the two coils it would be a "proper" wireless charger
Y
I would recommend putting a rectifier diode on the receiver coil so it does not damage your battery. Other than that everything seemed good. Great video!
I want the last five minutes of my life back
😂😂😂🤣🤣🤣🤣🤣🤣🤣🤣🤣😂🤣🤣😂🤣🖕🏻🖕🏻🖕🏻🖕🏻🖕🏻🖕🏻
Good job
4 real
Great til you get to the last step that's just stupid.
ahahahhHAhhhhH
DC Analysis of the circuit reveals that the 2N2222 NPN transistor's B-E (base-to-emitter) junction is forward biased and the voltage source is constant DC. Therefore, the transistor is always on. No change in magnetic flux = zero voltage in the secondary (the phone). The C-E current is constant because there are no circuit elements to force any voltage or current changes. The final result is that this gent made nothing more than an electromagnet - and a rather weak one at that. There is ABSOLUTELY ZERO change in the H-field (flux change = 0) and thus there is no induction effect. ZERO. People can say "Eureka!" all they want but this circuit would only make a great April 1 prank. By the way, the 2N2222 maximum, constant C-E current is less than 20ma. This circuit has no current limiting whatsoever and would "let the smoke out" of the transistor. Once the smoke gets out of resistors or transistors, they will not work again, ever.
B. Glenn it's you that doesn't know the basics. The 2n2222 plus the two coils make an oscillator circuit. It will oscillate at approximately 30khz and the magnetic flux will pass and produce current in the other coil.
"And then you just glue this shit to your phone, trust me, I'm a doctor."
k thx
Its the effect of induced current :|
Well played xD
Nice work 👍simple julie thief circuit ,it's good to add a diode in the secondary coil
The induced emf at the other end might be 5 Volt (to indicate charging status) but that would be alternating, there would be requirement of a full wave bridge rectifier to get it smooth as DC, and even so I don't think there would be enough current to pull the battery up, instead It will charge your battery down to 0%. It's a legit trial but not up to par.
People often get confused with Electromagnetic Induction (that is in dc developed by Michael Faraday) with the Resonant Inductive Coupling (that is used in ac as of lighting up bulb wireless and the one developed by Nikola Tesla) and is exactly the working principle behind wireless charger.
Exactly bro, idek how hes inducing current in secondary coil when u dont even have a change of phase in primary coil 😭😭😭 just see how transformer works 😭😭
Exactly bro
sorry i'm a kid i understand a part of it but not fully do you have some video explain about that?, and in this video it says ""Wireless power transfer using Resonant inductive coupling" ua-cam.com/video/AWhuu9TwMLM/v-deo.html what does that mean?
@@sciencekhuong imagine a magnet oscillating in a coil back and forth generating voltage .. now replace that magnet, by another coil switching on and off that generates alternating magnetic field (just like oscillating magnet in a coil back and forth) which i think would be layman explanation for resonant inductive coupling
@@ronvoy when a intelligent guy enters the comment section.........
No chance to work. The guy does not know the basics of Faraday's induction law. Alternating current is required in order to have induction. DC current from the power supply will only produce some heat to the primary coil after the transistor is burned. This circuit cannot even cook eggs
P
If it is a stepdown ac adapter then it could possibly work.
@@13thChip No. Without AC current, simply impossible.
@@svddsv3503i am referring to AC adapter that gives sinusoidal waveform at its o/p. It will work! I have seen many. DC adapters will not work.
Dc me work karta hai Bhai 😂😂
Kya padhe ho
Very nice video👍
Does it also work with the new Phones ?
How fast does it charge ?
Wouldn't recommend a metal container. Most metal types shield off induction. I mean it might work, but a plastic container would be much better. And it can also be a fire hazard, if you used a steel container the induction will cause the steel to become hot.
Hey. Come to my channel, leave your comments.
Freedom ok sub to me too
Anyway its fake. DC cant transfer energy over air
Raidzor つ ◕_◕ つ inductive reactance.
Guys I am a student a student and for our research we have this project. It would mean so much if you could teach me how to do this properly thank you.
Dude the amount of wires used to make wireless charger 😂😂😂
Missing some components - oscillator and capacitor to set resonant frequency
He just show how to transmit charge wirelessly.
Can you do the same method but have a Bluetooth board that powers two speaker components connected to the copper wire that is glued to the back of the phone? So in other words you would substitute the phone with a Bluetooth board.
Is it work on any smartphone 📱.?
But any way nice use of mutual inductance principles
*Can I use other transistor?*
this is 5v DC, and induction charging only supports 5v AC voltage.
Can we use phone cover because it is damaging back panel cover and look of phone
I woke up in the way you showed up. The LED wading under the hot sorbet swelled hot and fast, but it was overheating.
It’s awesome bro. I have tried it it’s working nice.
Are you stupid
Lea Anderson nah you are not them
If it works for them, it works
Directions unclear, burned my house down 😕
Do you need to make the part that goes onto the phone if u have an iPhone X?
Thanks you're wireless phone charger worked best
Cooking my phone.
What a amazing idea! It still connect in usb men..
LooooooL
4:38 charger light is on 4.51light off
Wirless tech can out 119 years ago ua-cam.com/video/oveNsd4c8Is/v-deo.html proff here
Nice wow u see good
💯
There around 10$ now; wires touching metal seem iffy to me but this a cool idea for the phone part if done right. Glued to the back is not ideal though.
why we need a bjt ic?
many thanks
How can this really work? The secondary coil gives alternating current. That must be rectified with a diode or a Graetz bridge.
Károly Varga you are right
How come it gives ac volt....it is connected to a dc source
It's totally fake for magnetic field we need to give AC supply but here directly giving dc to the coli for Dc it acts as wire and second thing secondary coil output must should be rectified before connected to the mobile so my conclusion its totally fakee
Ashwajeet Kamble by the oscillator circuit we can turn dc to ac but here no oscillator ckt is present so it's totally fake and foolish
saikiran kiran ya Ur right
Why don't you just plug your phone into the charger
hes stupid lol still need to plus an OTG to your doesn't make tthe charger wireless
Why have lightbulbs when candles are fine.
RIP farday’s induction law💀
this charger can charge the wireless charging supported mobile like lg g6?
Wouldn't it be simpler to just get a battery pack charger and safer as well and more convenient, once charged can be taken anywhere for recharging phone. They also have battery pack phone chargers that can be rechargeable with sun's solar energy. I will say it was a nice effort in a different approach to innovative application, however.
Gregory Trane Zaboor. meaning weep zaboor divine intervention weep to
what your saying is solar portable power bank. it is available in the market. and this wireless charging aren't meant for mobility. but it is meant for home simplicity. hope that clarified.
helpful for physics project tho
They have wireless power banks too
If it was that easy and cheap to make wireless chargers all the smartphone companies would have implemented on their every smartphone.
OM G I didnt said their aren't smartphones with wireless charging,there are
but every smartphone didn't because transfering energy is not easy and cheap,if it would the phones we all using would have wrless chrging
The above video pretends that u can make one urself that cheap????. Which in a scientific sense not true
Shubham Yadav but it is not efficient and takes up space
The video is fake because DC doesn't go over air. You need AC to transfer current and so you would have to hook up a transformer to the charger.
Raidzor つ ◕_◕ つ hey if u understand whats going on then this is not fake. just go on my channel. i have shown a dedicated video to this and how it works. basicly its a transistor ossilator
AWESOME EVERYDAY How's the video called?
sir Kya may BC 547 use ker sekte ha Kya
bro copper wire lena kitna hai....i mean kitti quantity honi chahiye usb or wireless charger coil dono k lye
Secondary coil's AC should be converted to DC with diode
Yes but the charger isn't even AC it's useless
@@alecrider5077 yes
I’m no expert. But isn’t wireless induction chargeing ac and it needs to be converted to dc?
what is the diameter of the copper wire you used?
hello,do u need the wireless charger ?we are the supplier of it ,and we can provide a great variety of the wireless chargers, if u interested it ,please contact me.
Stop hating on this guy atleast his yt is creative life and you dont need to put rude commets if you were true fans suport him then
bro channel owner does it really works or not plz tell truly....coz m doing thus same for my electronics practical....thnx
Powerbank zindabaad
😁
Much better option
Instead of 3 volt if I use 9 volt then the transmitter range will be how much
a fire hazard
Awesome Idea sr ji
Sir if we use dc current so it work 's
You can discredit this video right when you see he’s using a metal container to make the charger
Right
True
As well as the fact that he’s using a DC power supply. Magnetic fields only generated in a conductor with alternating current. And then the receiving coil has to be rectified (AC -> DC)
@@evanpautz6046 can you speak English
Dude, gimme your phone and I'll make it wirelessly chargeable.
Does this 4:28
Good job I'm gonna try to do it in my house
What's the results
Why did you use double coil windings @ the receiving end, and what's the function of the transistor?
Transistor work is to control its heat when it become over heated
Nice job bro
এটা তোমার মোবাইলের ব্যাটারি খারাপ করে দিবে
any battery is charged on DC voltage but you are making the dc from adapter to ac
because dc current can't pass through Transformers
what you have done I think it will affect battery life because instead of dc you are giving ac
Good job and Creative crafts
not sure how the AC is getting created? Do the junction cap (along with the coil) create an oscillator and thus giving out AC across the C-E junction?
puzzled!
Try this at iPhones 😂😂😂
I this this is may be a tricky video. This may not work. The charger uses a simple transistor probably which can switch max. 100mA of current through a coil! Horrible then the coil and transistor is packed into a metal container which acts like a shielding and damps magnetic field . Besides these losses and general losses this induces a current into the second coil which is directly connected to phone via usb port.!!!! Even if the field induces a magnetic field inside the coil then also the voltage produced will be ac and fluctuating do u think it is safe to charge this phone with it? ... Anyway's its fake .....
Btw.. well played trick 👍
Bro I have one doubt
For magnetic field we need to give ac supply but here directly giving dc supply to coil does it works are not
electronic _artist_ Plz talk with me on WhatsApp I need ur help
give me ur no. or my no. 9924500464
saikiran kiran
yes it is not necessary to producing variable Magnatic field AC supply is needed.... but u also produce it by using two Magnatic field resultant...here transisor is divided primary Coil in two part and resultant field produce variable Magnatic filed.... but in this video this guy directly connected his phone with secondary Coil...this is never charge ur mobile... even u connect full rectified circuit then also it not work bcz with rectified current is may be around only 60 milli amps....it just show that ur phone charge but actually charging not rises......
don't use this on ur mobile without any perfect knowledge.....
don't make this types of full videos...
Finally someone who understands stuff, cheers man!
hi, can the coil be smaller ?
Hi how to meke DC motor
Power Genaretor plz meke video
something missing well let me tell
"he basics of Faraday's induction law. Alternating current is required in
order to have induction. DC current from the power supply will only
produce some heat to the primary coil after the transistor is burned"
u need to follow the rules dumbo
Put that coil aroung your head and plug it in the 110 you will see how fast its change lol
LOL
most mind man & good attitive
Bhai ye btao agar m apne mobile ko es coil se attech keruga to mobile ke plus+ and negative tarminal - dono miljayege or meri bettri kharab ho sakti h to ek kaam or kr sakte h jb apn indonu to coil se mila rehe h usse phale donu trminal pr dayoad laga de
Dayod ka kaam hota h ki current ko aane deta h, vapas nahi janedeta esko fayada hoga esse hamere mobile ki battri kharab nahi hogi
it will damage the battery
rohan pednekar no it wont
rohan pednekar yeah, you need a rectifier to make sure it will go in one polarity
atomicjellyfishdragon yes i have used a FULL BRIDG RECTIFIRE and a 1uf capicator rated at 16 volts to smooth out the wave formed
AWESOME EVERYDAY cool
AWESOME EVERYDAY and I don't recommend using a metal container, it deflects induction waves. It might work, but it usually doesn't work. And if it is a steel or copper container, it might create a fire hazard. Use plastic as the best choice. Or glass.
yeh warless he ya war jayda he
mobile tips india dosto wswdwdw
War nahin wire
Fake hai
You are right
Nice work. I also made the same one
Does it work?
super a home made activity😍😍😎
it's not fake
it's based on the design of mini tesla coil
and parts are either available online
or you must go to an electronic market
but these parts are super cheap
the wire is also not the normal plastic insulated wire
this is another kind of wire
check it on any motor shop

This won’t work, at all. You need AC for inductance, and that would also require a bridge rectifier on the receiving end of the circuit plus some form of resistance and a 5v regulator. (Most phones use 5v 1a for charging)
AxiomaticUncertainty THANK U SO MUCH. I'M DAMN TIRED OF RE-EXPLAINING THIS TO IDIOTS like this fake UA-camr!
:)
Correct
this is for iphone users.....😂
Nice cooking stove you did there.
Hello sir. Can we use them for iPhone 5. Please. Comment me
this is how to start a fire at home
This is so fake hahahaha! You need AC current at the source for wireless charging but the power source is DC current, his mobile adapter so it's obviously fake...
Electric and magnetic fields are present around any electrical circuit, whether it carries AC or DC electricity and also capable of producing a magnetic field. This is how AC or DC motor works. inductive coupling principle is used here. To know more Refer below link:
en.wikipedia.org/wiki/Wireless_power_transfer
ram rachaveeti Yes genius but DC current can't induce stationary objects.
Thats true Einstein, That is the reason Transistor 2N2222 is connected in the circuit to make sure the DC current supplied is changed into high frequency AC current. In the TX (transmitter) section, the AC current in copper wire creates a magnetic field. Once an RX (Receiver) coil is located near to the magnetic field, then the magnetic field can induce an AC current in the receiving coil. Electrons in the receiving device, converts the AC current back into DC current, that becomes working power.
Not only that but you can see how he didn't even plug the charger in to the charging port because it would of fried his phone if he did lol
Is there any way to charge a lithium polymer battery directly by this technique?
You can use a 5v REGULATOR
You said its wireless but why is there copper wire? hahahaha
exposed
LOL
BUT U SEEM TO BE AN IDIOT ``WIRELESS`` MEANS THERE IS NO WIRE BETWEEN THE TWO CHARGING POINTS....
BETTER GO FOR ENGLSH CLASSES!!!! :P
SMITH RODZZ you better go to spelling class
SMITH RODZZ and grammar class
ItsMe Kyla u dumb?
"wireless"
Yup. That's what it is.
esta muy bueno y todo pero faltarian algunos diodos para evitar dañar la bateria esta genial sabes pero oye faltan los diodos
Well done New Idea. No one knows this type of idea
Tech Study everyone except you🤷♂️
Fake video mat bana
Banay ki nhi frr isko kya ye real me kaam karega
MOHAMMAD RASHID it will work dude but it's not safe to charge it phone with it cause there I nothing to smooth the voltage (ac) which is going in the phone...u need a full bridge rectifier and a capacitor
This vide is fake im try this is fake gays .. Don't west charger ..ok
Munawar Ali i know
This video is fake because wireless charger works on principle of mutual induction but when we give DC supply it acts as wire and it would be burn so when we give ac supply it produces magnetic flux then it satisfies mutual induction soo this video is fake
I don't know its work or not and fake or not . But i cheak in wireless charging torch which is work on same processor
saikiran kiran they used transistor for the D. C issue.... Dont make fucking comment like cow...
saikiran kiran what you said is correct,and that's the reason why 2n2222 transistor is used,it converts the dc supply to AC ,and hence magnetic flux is produced.😊
charger mobile ka kam kary ga or 2n2222 trnster or konsaa use hoga
great idea....
Will we get shock if we touch the container when the charger is on.
YOU ARE A GENIOUS!
can we use bc547... by placing to reverse direction plz reply!!
¿? Don´t know. LOL🍠😓😀
do we need nfc to use it
Sei veramente bravo!!
Thank you sir
the part where u stuck the coil on ur phone isnt necessary today, most phones have wireless charging. But the other one is really good. Might try this at home
can work on 9v 2a
Working... Thanks.. Keep it up
Its *maybie* working if u use plastic container .
I did the same thing as u did in the vedio.
But i am not recieving current signals in the coil
What could be the reason
Plz help
And reply as u read this message
It is my electronics project 😋
It will not work! Because DC current cannot create an induction. It's totally bogus
The current releases from the magnetic wire is ac, you'll need to convert it to dc in order to charge the phone, by the way you'll making electric stove dude, you wonna cook your phone?
Mistakes
---------
@ You better connect a rectifiier to the secondary coil before connecting it to the phone.
@ Also the no turns in primay and secondary coil must be equal
plastic use krle hova???
This is the first time im learning to make something becasue I dont have the money to buy something
Hei bro,, please halp me,, I'm already this project making and the show led light but why not charging my phone.....?
@ravi raj thanks for your replay,,but I don't understand ,, say it again
@@mdaminulislam-uk3df It's important to really turn the wire 15 times around the can. You maybe counted 14 or 16.
