I wish the Arduino course was in English:/
Plz tell me all components
Sorry sir..Can you make output from receiver more big?example 5v 20watt
This video was not just about wireless charger. It contains lots of necessary informations 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.
Not gonna lie... You are actually becoming my favourite youtuber.... Keep it up with this awesome content
So glad you say that. Thank you!
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.
He is on the list of *top ten best* content creators on TH-cam (at least)
Meeeeee toooooo
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

Man, I think your vids are helping students more than most university lecturers!
Good job and very well put together. This is probably one of the best videos explaining the process!
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!
This is the 700th video I liked on TH-cam ❤️
Great well explained video...keep up the good work !
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!
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.
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
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!
My goodness, what a wonderful explanation, I appreciate your work, thank you.
Outstanding! Great job! You killed this video, keep up the amazing work. 👍
I love how you explain things... That is what I need.
Would have been neat to see the difference in power loss between your home made charger VS the commercial one.
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 :)
The best video ever I needed....
Was searching this since ages....❤❤❤
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
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.
Thank you very much for your comment. :))))
You have great visualization and explanation. Good job
this is the most detailed DIY wireless charger I've see so far
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😃😃
This is an amazing video as always. I love your delivery approach.
Wow... beautifully explained. Love what you do. Teach us more... 😊😊
Thank you, It reminded me some subjects of my electronics degree that I already forgot,its being a while since that
Man your video here was super week made and well explained. Very educational. Thanks ❤!
very efficient and unlaboured explanation. Thank you!
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"
Best video on this topic by far!!! Thank you!
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❤️❤️❤️
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
Excellent video ! Well explained and also very entertaining !
You're editing is awesome👍👏. Great video.
Dear: Congratulations on a great video on the wireless subject! Thanks
great video, subscribed immediately !! One question, do you think would it be possible to have the induction power on a coil along a cable/wire and the the coil with the LED on a U shaped coil that hook on the wire to light it up? Just wondering can you have the power on a cable an be able to hook the LED coil in every point you like along this cable and be able to power the LED? thanks
Thank you, thank you!!! Now i know how it works. Excellent!!!
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!
You are a master in electronics!!!
Super Video. Danke fürs Teilen. 🙋🏼♂️
Thank you that's indeed a detailed explanation
thank you very much
it was a creative way to explain the magnetic field
This video is great. I was looking for this exact stuff. I have a question regarding wireless charging.
I have to power a laser operating at 5VDC @ 110 mA. The laser is mounted on a rotating shaft. Is it possible to power the laser wirelessly?
I intend to mount the receiving coil on the shaft, the transmitting coil can be 10 mm distance ( the shaft goes thru the center of the coils).
The transmitting coil is fixed to the base. So now only the receiving coil rotates. Will the wireless charging work even if the receiving coil is rotated? Will speed of rotation matter? What if rotation is slow?
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?
I really like this device type. It makes my battery-charging life easier.
Neat. I've found information for my paper on receiver module of contact wireless charging
Deep explanation keep making love you
Perfect explanation sir
What an explanation ,Great work sir...
This is very good wireless charging intro. The tech explanation level is JUST RIGHT. I found it to be very useful. LIKE and SUB
Bravo...you gotta subscriber. What an explanation for people having very littlr electronics background
Very informative. Thank you.
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?
Thank you for this video dude ✌️
Can we remove the rectifier by powering the primary (transmitter) coil with lithium DC battery?
Thank you for your great work!
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
Great explanation as always thanks 😀
Btw are you having any plans on making a rc paper airplane you talked about in a video about the Arduino nrf24 reciever?
I want to make the rc airplane.
Cool thank you. Very informative and interesting.
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 ?
Good , I am impressed with your explanation.
Very informative,thanks...
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?
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?
Very very informative and interesting subject 👌👌
YOU ARE AMAZING, the CONTENT IS JUST WOW!!
This is awesome tutorial, very useful for me. I want to make a inductor coil long, say 1.5m long. The receiver moves parallel to the coil, I only need 5V, 300 mA
Is it possible to make this? Are there any readily available? I am trying to eliminate a drag chain used to carry power to a sensor.
Continue such vedios
You will definitely millionaire (subscriber)
Very nice material! Thank you!!
I need some help with an mpu6050. Can you keep the same 0 degree value of the gyro after rebooting with the sensor starting in another position using esp32?
Is there a size limit for the output coil? Can the loop of copper be several feet wide? I'd like to incorporate a huge wireless power device into a dining table so that any wireless device could be charged regardless of where on the table it is.
Thank you very much. this helped a lot💛
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 🙊
Enjoyable video! 👍
Try swapping those 1N4001 diodes for 1N5819 schottkys, the 4001 are very slow and are costing you energy efficiency. 🙂
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.
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.
The world's best teacher
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.
very informative thank you
Thank you!
Hello, could you explain what for are those 1 nf and 4.7 nf caps at mosfet gate? Thx!
you are becoming better and better, it would help me a lot if you could make a mosfet bootstrapping tutorial,?
Hi, I just builded it myself but the light on my test led soldered with a receiveing coil isn't stable as yours but keeps blinking. I checked the voltage at my input (one charger of 12 V and 0.5 A) at the voltaged droped to 1.2 and starts oscillating between 1.2 and 1.5 V, which I believe, must be the reason for the blinking led. Can you help me figure out why the voltage is unstable?
What power supply should I use to induce current, any step down transformer of 5 v ac if i connect to coil will work ?
if we make a set of copper coil (reciever,transmitter) than in reciever can we use bridge rectifier to convert ac to dc and connect the output to usb for charging?
Very informative, got yourself a subscriber here.
Great video! Where I can found that coil's rules respect calibers, inductance and diameters to make a personalized ones? Thank you in advance!
What video software do you use that makes annotations follow the video content?
Really good bro! Enjoyed it.
But i am trying to do this exact project with some friends for our final test (11th grade eletronics and telecom). We only have two weeks left and it is not woring, we dont know why... wee use the osciloscope and there is no signal coming to the reciever or coming out of the transmiter. One of my teachers said maybe the wire we are using is too thick, so we would like to know what is the diameter for the wire you used.
Also if you have any other tip i would apreciate if give it to us as quick as possible😩
Realllly nice! Thanks, man! :D
Very good project 👍
Super bonne idée trop cool
Thank you 🥺❤️
Fantastic video for my high school physics students...
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 man and very nice explanation. But I dont get why you say "it'll work better for charging electric cars" ? The efficiency percentage isn't going to change is it ? So since charging an electric car obviously requires much more enegry to charge, the energy lost would be greater right ?
Really Great explanation
Very clear an useful!
Very good experiment 💡🤩
