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.
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❤️❤️❤️
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"
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!
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
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
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 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 :)
Hi, thanks for the video it helped me and my friend a lot while we were trying to transfer energy wirelessly using solar panel as an energy source but when we connect the middle leg to the power source the circuit didn't work which made us wonder what would be the reason? Could it be because of the coil? we couldn't find 0.8mm coil so we did it with 1.0mm coil. We also try to use dc power source as you did but correspond with the same problem. Thanks for your help in advance and for the video.
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.
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
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?
Uhh... i have a few questions 1: Instead of the mosfet you use (In the transmitter circuit) smd can we use another mosfet 2: Can we make the receiver and transmitter circuit smaller? Note: I am Turkish and Using Google Translate, Sorry for typos
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 .
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 ?
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 🙊
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?
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?
Hi there! I was wondering if you could help me with a DIY experiment I’m working on. I’m a barber and I’m trying to modify my wireless clippers to be wireless charging too. I was thinking of purchasing the receiver and soldering it to either directly to the lithium battery or to the area where the charging wire receiver is.(sorry for my lack of terms 😂 I know how somethings work from experiments I do but don’t really know the terms of the stuff. My second question is, once modifying the clippers, would I be able to use any other wireless charging ports or do I have to buy and use the same transmitter for the receiver connected to the clippers? Hope to hear from you soon! Thanks for the informative videos! Keep at it ! I love your channel. Learned a lot from it u have no idea 😂 thanks again bro
Also ! I forgot to mention. There is a company called Tomb45. They make wireless charging matts and power clips that can be attached to the charging port of the clipper which once attached and placed in the mat, can charge the clippers wirelessly. It’s totally cool except i don’t want to have a power clip attached but instead modifying the clipper from the inside. Which is also why I had the idea of directly connecting it to the charging port spot inside the clipper. I understand depending on the size of the module I may have to modify the shape of the clipper case too but that’s no problem as I modified the case many times before, like you would when modifying a cars sharpe to fit new components. Thanks again bro and my apologies for the long comments by the way 😂
@@ELECTRONOOBS I was curious about one thing.....do you know python??? Cause I moved from Arduino to python( I still make projects) but I am learning python....so if u know python it would be really great if u could upload python basics tutorials.... thanks
Awesome video!! Can anyone explain to me why this sort of technology is not being used to charge batteries that run the transmitter. So the transmitter is being ran off a battery, DC, to an inverter to AC current into the transmitter coil to send it over to the receiver coil where the receiver charges two batteries and uses one to run the transmitter while the other battery runs whatever. Can that not work?

Good job and very well put together. This is probably one of the best videos explaining the process!
this is the most detailed DIY wireless charger I've see so far
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 very much for your comment. :))))
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😃😃
Would have been neat to see the difference in power loss between your home made charger VS the commercial one.
I could learn this stuff only from your videos, Never learnt much in college
The world's best teacher
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❤️❤️❤️
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"

Fantastic video for my high school physics students...
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.
Thank you, It reminded me some subjects of my electronics degree that I already forgot,its being a while since that
I don't like videos very often, but when i do, they have the same quality as these one

YOU ARE AMAZING, the CONTENT IS JUST WOW!!
hey... i want to know you have given a ac or dc supply from the cro to the charger??
thank you very much
it was a creative way to explain the magnetic field
What an explanation ,Great work sir...
Wow... beautifully explained. Love what you do. Teach us more... 😊😊
Neat. I've found information for my paper on receiver module of contact wireless charging
Technically well informed. Kindly let us know high wattage wireless charging module DIY
Very good project 👍
Man your video here was super week made and well explained. Very educational. Thanks ❤!
No one can beat you in hearting❤️ UA-cam comments...👍👍
This is very good wireless charging intro. The tech explanation level is JUST RIGHT. I found it to be very useful. LIKE and SUB

Excellent video ! Well explained and also very entertaining !
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
This is an amazing video as always. I love your delivery approach.
Dear: Congratulations on a great video on the wireless subject! Thanks

Thank you, thank you!!! Now i know how it works. Excellent!!!
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?
Uhh... i have a few questions
1: Instead of the mosfet you use (In the transmitter circuit) smd can we use another mosfet
2: Can we make the receiver and transmitter circuit smaller?
Note: I am Turkish and Using Google Translate, Sorry for typos
what is the resonance frequency that you used here?
Very nice thank you and keep it up bro
Great video! Where I can found that coil's rules respect calibers, inductance and diameters to make a personalized ones? Thank you in advance!
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 .
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.
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 we use 20 volt Vcc input dc voltage if we use what is change in transmeter circuit please help me to execute these circuit
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 🙊

and if phone ran out of battery, device usually take 1A to charge battery and keep cpu alive. could low amps harm device ?
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
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?
could you explain or make cut off circuit for battery when its full?
What is the input range which we are going to give in transmitter circuit
Perfect explanation sir
did you use insuated copper wire????
Very informative,thanks...
