This video was not just about wireless charger. It contains lots of necessary information for anyone curious about electronics. That was educational. Thanks !
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.
Been watching him for a while, your instincts are spot on. He's already good and only getting better. Wish more of my teachers had his casual passion. He and great Scott are like, my go to's.
Dude that's so funny man my first words when I heard him talk like omg this dude is the best yesssss! So it's funny to hear other people say similar lol
Guys a genius with switch mode power supply, I've downloaded every smps video he has. Of course I paid respect and liked and shared and enjoyed evlach video on his channel first before downloading. Gotta look out for him the only way we can
THAAAAAAAAAANKS A LOT FOR THIS VIDEO!! I find so hard to understand things unless they are explained visually and from the very beginning and the underlying topics as well. I just get so excited because I wish everything was explained this way!! You make it so easy to understand and your voice is not boring at all! Thaaanks!
I know this is an older video, but thanks for laying it out in a clear way, and you ordered the information just right that I could actually figure out the implications instead of it being spoon fed. I already figured out the full bridge rectifier into a capacitor store and regulator combo before it was even mentioned because of the clear and well ordered delivery. Thanks.
Honestly speaking, I used to not care about your videos earlier, but as time prolonged the quality of your videos raised exponentially with awesome illustrative graphics and lay man term explanations. Loved the videos really...keep up the awesome work and provide with more useful content...I recomment to make a video on PCB design and layout for RF PCB's(atleast try implementing this in your videos) . Thanks in advance.
This was such a cool video. we appreciate your hard work. it was perfectly explained as if its a story of someone inventing it. i like this style better. cant wait for your next video. keep em coming!
I love the very helpful instructions of winding the tank coil on the transmitter circuit appearing at 06:29 which says................., "6 Turns ( 3 + 3) Center tap is in the Middle"
Watched and Subscribed straightway. There's no way you can make stupid marketing videos. Excellent work and big thanks for making this type of content.
Now I came to what is flux , how current induces from another coil, I learnt lot from this video. ❤️❤️❤️ Thanks .you r great and incredible, lot of love from India❤️❤️❤️
wow tysm! I wasn't expecting to get it yet after watching just one video and reading a few things online, but I understand it so much better now. I've never heard someone give such a good explanation of a semi-complex topic before :) --or at least, it didn't seem simple to me before haha. It was simple enough for anyone to follow, but you still went into the details to really understand what is going on, why, and how the variants interact. You're an excellent teacher!! Thanks for sharing this
the IC on both the receiver and Transmitter are for communication with the exception of the transmitter doing double duty as communication and Mosfet Driver, The comms portion of the transmitter is for Smart charging. the short pulses from the transmitter is basically the transmitter asking "Anyone there??" However it also serves as a non compatible object detection and will prevent charge mode. When that pulse hits the receiver it wakes its IC and responds "yes I am here, Start charging" once the handshake is made, it begins the charging process but also monitors the current draw from the device to be charged. The more the device tries to pull determines the Fast Charge state. If current is low enough it charges at 1Amp all the way down to 200mA. If supported by the transmitter "QC Fast Charge" the transmitter will send up to 2-3 amps depending on the QC level
Holy shit, you explain these concepts so well. I'm recently starting to learn more about electronics and well this was a great lesson. You've earned my subscription!
Hello Andrei, ♥ your content. Could you please explain how you designed the transmitter circuit and what role each component has in the circuit? Thank you, lots of love :)
well done, very cool to see you walk through the pretty precise steps. Maybe do another video to summarize all the embarrassing failures and what to learn from them... they always happen
At 6:27 why does the coil now have three connections. I didn't quite get how that schematic works than 🙉 in your LC tank example before the inductor and the capacitor where in series or in parallel but now there is the mosfet in between. Could you explain that to me please 🙊
how about lower voltage and amps? voltage regulator garantee maximum of 5V but does 2V harm mobile battery or chip ? and if phone ran out of battery, device usually take 1A to charge battery and keep cpu alive. could low amps harm device ?
Great job, I tried to replicate myself but I can't achieve the desired voltage on the reciever. Wheneever I connect the coil on the transmiter, the voltage from source, drops from 12 V to 1.2 V, I believe it is because of the induced emf, do you have any idea what could be wrong?
So to create a first part , should I use ac 5 v to a coil to see if it can induce the emf to other coil ? I am planning to use a step down ac transformer. Am I going right ?
can you also put set the mini spy camera directly attach on the electricity bulb cables above the bulb? and can the spy camera be connected to electricity separately to the bulb? I have 3 cables for 1 bulb at home (European type). I want to know how it works. thanks.
I have recently constructed everything you have done for this project. really enjoyed the process of making it and learned a lot long research. Only one thing I couldn't find, which is the type of oscillation is used at the transmitter stage?? I was able to find that it is a modified Royer oscillator in one article. But again no explanation was found, so I am unsure if that's right. I would like to hear anybody's opinion too. the reason why I want to know this, coz there is no resonant compatibility between the two circuits. resonant frequency has been only determined for the transmitter stage but not for the receiver stage.
9:29: When the smartphone starts charging, why does the power draw from the PSU actually decrease? Should it not increase? There is 1.4W no-load consumption. After the charge starts, the consumption is 1.3W, any explanation on this?
Hey >>>>>>>>>>>>>> for the Transmitter do you have like 2 coils inside each other ? Why? how fast is the alternating input? is there is a way to maximize the AC input speed?
would this work with an iPhone 11? The iPhone has the receiver coil already inside (since iPhone 7). So wondering if I just build the transmitter unit if it will work with my iPhones?
You forgot to talk about the skin effect . It's that when a high frequency current is passing in a conductor it passes only on the skin of the wire . That's why the commerical charger has thay type of wire which is a lot of thin wires twisted together . That's also why some high frequency SMPS transformer wires are thin wires winded together on parallel to reduce the skin effect .
great job i really enjoyed every second, just one question for the one you made you provided AC voltage but what if we want the transmitter to be powered form a power bank as you showed at the end of the video how can we overcome that power banks provide DC voltage
Hey chap, thanks for the video, wondering if you have time to help me a little? I have a permanent Lego train track which is going through batteries at a rate of knots. I would like to use wireless charging built into the track so when the engines are at rest they can be parked over the charger to recharge. The problem i have is that they run on 9v supplied from the Lego proprietary battery box that holds 6 aaa batteries. Is it possible to make a wireless charger that will charge one of these boxes without having to remove it? Thanks again. Tanc
Great video. I am working on a project and I could use your help. Do you do consulting? I need two things. I want to make a wireless transmitter that is large enough to put a dozen receivers on top that will produce a charging voltage of 5 volts. Something the size of a dinner plate. Do I simply make a bigger wire coil? If I did would it overload when several devices are above it?

Man, I think your vids are helping students more than most university lecturers!
This is by far the best video on this topic I've seen so far. You did a great job of explaining this, AND you actually listed the parts! Great job!
THAAAAAAAAAANKS A LOT FOR THIS VIDEO!! I find so hard to understand things unless they are explained visually and from the very beginning and the underlying topics as well. I just get so excited because I wish everything was explained this way!! You make it so easy to understand and your voice is not boring at all! Thaaanks!
This is the 700th video I liked on TH-cam ❤️
Great well explained video...keep up the good work !

whats so funny ?
The best video ever I needed....
Was searching this since ages....❤❤❤
Would have been neat to see the difference in power loss between your home made charger VS the commercial one.
Honestly speaking, I used to not care about your videos earlier, but as time prolonged the quality of your videos raised exponentially with awesome illustrative graphics and lay man term explanations. Loved the videos really...keep up the awesome work and provide with more useful content...I recomment to make a video on PCB design and layout for RF PCB's(atleast try implementing this in your videos) .

Thank you very much for your comment. :))))
this is the most detailed DIY wireless charger I've see so far
Next: "Induction cooker"
Ummmm yes plis
Next: wireless charging circuit for Your electrical car
"Hun, have you seen my phone?"
"Yeah, I put it on the induction cooktop - it charges wirelessly, right??"
same video
I had to make a presentation about this and you were the only guy with just what I needed, it went extremely well thank you!
I'm currently making a custom copper coil, your video was very useful! Thanks!
Thank you for this Video, you are a Teacher for a lot of engineers around the world !!!!
Good you say engineers. This is all very strange to me. Fascinating though😃😃
The world's best teacher
This was such a cool video. we appreciate your hard work. it was perfectly explained as if its a story of someone inventing it. i like this style better. cant wait for your next video. keep em coming!
I could learn this stuff only from your videos, Never learnt much in college
great video. you make it way easier to understand how things work while at the same time allowing up to not be restricted on what we can make.
Can we remove the rectifier by powering the primary (transmitter) coil with lithium DC battery?
I love the very helpful instructions of winding the tank coil on the transmitter circuit appearing at 06:29 which says................., "6 Turns ( 3 + 3) Center tap is in the Middle"
I don't like videos very often, but when i do, they have the same quality as these one

Outstanding! Great job! You killed this video, keep up the amazing work. 👍
Thank you, It reminded me some subjects of my electronics degree that I already forgot,its being a while since that
very efficient and unlaboured explanation. Thank you!
well done, very cool to see you walk through the pretty precise steps. Maybe do another video to summarize all the embarrassing failures and what to learn from them... they always happen
Best video on this topic by far!!! Thank you!
9:50 that's literally my exact phone case yoooooooooooo
Continue such vedios
You will definitely millionaire (subscriber)
you are becoming better and better, it would help me a lot if you could make a mosfet bootstrapping tutorial,?
Bravo...you gotta subscriber. What an explanation for people having very littlr electronics background
I love how you explain things... That is what I need.
I really like this device type. It makes my battery-charging life easier.
hey... i want to know you have given a ac or dc supply from the cro to the charger??
You have great visualization and explanation. Good job
Is it possible to change the 5v power to 3.7v from the circuit of the wire less charger if we put a step down module
Actually , I have a 3.7 18650 battery for charge with wire less charger
Wow... beautifully explained. Love what you do. Teach us more... 😊😊
Can we use 20 volt Vcc input dc voltage if we use what is change in transmeter circuit please help me to execute these circuit
You're editing is awesome👍👏. Great video.
No one can beat you in hearting❤️ TH-cam comments...👍👍
Man your video here was super week made and well explained. Very educational. Thanks ❤!
did you use insuated copper wire????
Whats the use of the other capacitors and the registors in transmission circuit??
My goodness, what a wonderful explanation, I appreciate your work, thank you.
At 6:27 why does the coil now have three connections. I didn't quite get how that schematic works than 🙉 in your LC tank example before the inductor and the capacitor where in series or in parallel but now there is the mosfet in between. Could you explain that to me please 🙊
You are a master in electronics!!!
YOU ARE AMAZING, the CONTENT IS JUST WOW!!
4:34 how is it possible that the LED works with alternating current?
The LED is still a "diode" itself, so it will automatically rectify half of the AC signal ;)
Excellent video ! Well explained and also very entertaining !
Super Video. Danke fürs Teilen. 🙋🏼♂️
This is very good wireless charging intro. The tech explanation level is JUST RIGHT. I found it to be very useful. LIKE and SUB
will any one help me , as i want to know that in input circuit we are giving AC 5v or DC 5v from the adapter .
Dear: Congratulations on a great video on the wireless subject! Thanks
Neat. I've found information for my paper on receiver module of contact wireless charging
This is an amazing video as always. I love your delivery approach.
Very wonderful video, however i have a question: how do you calculate the number of loops you'll need?
its directly proportional to the inductance value.
Thank you, thank you!!! Now i know how it works. Excellent!!!
how about lower voltage and amps?
voltage regulator garantee maximum of 5V but does 2V harm mobile battery or chip ?
and if phone ran out of battery, device usually take 1A to charge battery and keep cpu alive. could low amps harm device ?

can you also put set the mini spy camera directly attach on the electricity bulb cables above the bulb?

could you explain or make cut off circuit for battery when its full?
Good , I am impressed with your explanation.

Hey >>>>>>>>>>>>>> for the Transmitter
do you have like 2 coils inside each other ? Why?
how fast is the alternating input? is there is a way to maximize the AC input speed?
Bro mine z44n is quickly burning even i add heatshink but its still burning and i am losing my money
Please give a solution.
Very informative, got yourself a subscriber here.
would this work with an iPhone 11? The iPhone has the receiver coil already inside (since iPhone 7). So wondering if I just build the transmitter unit if it will work with my iPhones?
Technically well informed. Kindly let us know high wattage wireless charging module DIY
You forgot to talk about the skin effect .
It's that when a high frequency current is passing in a conductor it passes only on the skin of the wire . That's why the commerical charger has thay type of wire which is a lot of thin wires twisted together . That's also why some high frequency SMPS transformer wires are thin wires winded together on parallel to reduce the skin effect .
for some one that want to start doing circuit, do you have a video talking about tools for cheap vs expensive and the different between the two
what is the input voltage supplied in transmitter circuit ?
great job i really enjoyed every second, just one question for the one you made you provided AC voltage but what if we want the transmitter to be powered form a power bank as you showed at the end of the video how can we overcome that power banks provide DC voltage
Sir , is there any specific more components needed in the transmitter circuit for the efficent working?
...
What is the input range which we are going to give in transmitter circuit
Thank you for the informative video!
What power supply should I use to induce current, any step down transformer of 5 v ac if i connect to coil will work ?
Great video! Where I can found that coil's rules respect calibers, inductance and diameters to make a personalized ones? Thank you in advance!
whats the difference between the esp32s(used in espcam module) and esp-wroom-32, please explain.
you liked my comment but didn't replied
8:10... Why not use Schottky Diodes. They have a much lower voltage drop across them. I would also us a VERY low dropout Regulator.
Also the 1n400x diodes are terrible for higher frequencies. At least he should use uf400x diodes. But the video was very good and informative.
Is the schematic some kind of Slayer Exciter...it's looking very simular to it.
Can you guide if i can use 9 v battery to lit a led using this law
Hey chap, thanks for the video, wondering if you have time to help me a little? I have a permanent Lego train track which is going through batteries at a rate of knots.

Hello, could you explain what for are those 1 nf and 4.7 nf caps at mosfet gate? Thx!
What an explanation ,Great work sir...
7:29
Don't you mean, increase the windings? For higher output voltage.
Just a doubt, why do the diameter of transmitter (which you made) looks bigger than the receiver even though you said both have to be same diameter?
Great video. I am working on a project and I could use your help. Do you do consulting? I need two things. I want to make a wireless transmitter that is large enough to put a dozen receivers on top that will produce a charging voltage of 5 volts. Something the size of a dinner plate.
