Plz tell me all components

[@panjibukanpetualang3345]

Sorry sir..Can you make output from receiver more big?example 5v 20watt

[@komedikervanii]

This video was not just about wireless charger. It contains lots of necessary information for anyone curious about electronics. That was educational. Thanks !

[@aaralynyuegeng4349]

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.

[@bitsurfer0101]

*information.

[@wisnueepis3593]

You have great visualization and explanation. Good job

[@lux-nocopyrightmusic]

Best video on this topic by far!!! Thank you!

[@xiaoyi982]

This is very good wireless charging intro. The tech explanation level is JUST RIGHT. I found it to be very useful. LIKE and SUB

[@nuwanatthanayake]

What an explanation ,Great work sir...

[@credoonthebeat]

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😩

[@RoseKnight04]

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?

[@aisuka8200]

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

[@aisuka8200]

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 😂

[@yohannesandegergsh8620]

4:34 how is it possible that the LED works with alternating current?

[@ELECTRONOOBS]

The LED is still a "diode" itself, so it will automatically rectify half of the AC signal ;)

[@leks341]

Hello, could you explain what for are those 1 nf and 4.7 nf caps at mosfet gate? Thx!

[@kamaldeol8606]

Can you guide if i can use 9 v battery to lit a led using this law

[@nikhil.kale6892]

Thank you 🥺❤️

[@faridhousni2966]

Thank you very much

[@electrohub9100]

Can i use 22swg coil wire

[@559dime7]

what if you put the transmitter into a sphereical loop

[@backdemoletor4654]

Not gonna lie... You are actually becoming my favourite youtuber.... Keep it up with this awesome content

[@ELECTRONOOBS]

So glad you say that. Thank you!

[@lexscarlet]

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.

[@heyderaliyev8976]

He is on the list of *top ten best* content creators on KZbin (at least)

[@bparker86]

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

[@bparker86]

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

[@mrbojinkles22]

Would have been neat to see the difference in power loss between your home made charger VS the commercial one.

[@seanocansey2956]

Man, I think your vids are helping students more than most university lecturers!

[@your.free.electrons]

This is the 700th video I liked on KZbin ❤️ Great well explained video...keep up the good work !

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 :)

[@ravuthoum3626]

Good job and very well put together. This is probably one of the best videos explaining the process!

whats so funny ?

[@capistor1]

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!

[@lemonbubble1243]

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!

[@gudimetlakowshik3617]

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.

[@ELECTRONOOBS]

Thank you very much for your comment. :))))

[@arshammor3729]

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 ?

[@H-qk3xj]

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 .

[@vaibhavmate9201]

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

[@Umangpatel-np5xm]

Bro mine z44n is quickly burning even i add heatshink but its still burning and i am losing my money Please give a solution.

[@gamingwinneralpha]

Can we remove the rectifier by powering the primary (transmitter) coil with lithium DC battery?

[@bananabarnabis]

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!

[@dominicmillerca]

I'm currently making a custom copper coil, your video was very useful! Thanks!

[@aditya_patil]

The best video ever I needed.... Was searching this since ages....❤❤❤

[@damascussteel672]

Thank you for this Video, you are a Teacher for a lot of engineers around the world !!!!

[@drevil2783]

Good you say engineers. This is all very strange to me. Fascinating though😃😃

[@mosta5]

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 .

[@kumariefernando9617]

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

[@kumariefernando9617]

Actually , I have a 3.7 18650 battery for charge with wire less charger

[@69iqtutorial]

you are becoming better and better, it would help me a lot if you could make a mosfet bootstrapping tutorial,?

[@Techn0man1ac]

Забавно... Эти технологии применял ещё Никола Тесла, столетие назад...

[@AhabweTevin-nq9dv]

did you use insuated copper wire????

[@Sekhar_Home]

Pls post youtube for tm1638 or max led ic programming from scratch... This will b very helpful

[@rahulkushwaha1984]

You forget another point of differentiation between your crude setup and the one available in market that you're using single core wire and in commercial one's they use litz wire, which consists of many strands of thin copper wire isolated from one another. Maybe you just don't wanted to dump all the physics related to skin effect and losses that occurs due to high frequency to new engineers. I get that.

[@damnminecraftian7433]

Your circuit doesn't work

[@ShahZahid]

yep so my guess was correct, well it was pretty obvious in the teaser u uploaded

[@johntello8904]

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!

[@ehabmohamed8798]

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

[@keithfetterly4111]

Outstanding! Great job! You killed this video, keep up the amazing work. 👍

[@sayeretmatkaal]

Superb video ! I sooo LOVE the basics to practical videos ! Though I must say this type of "wireless charging" is EXTREMELY DUMB. If the phone could be charged while it was being used ANYWHERE IN THE HOUSE, then it's a great & valuable idea But a phone you CANNOT USE FOR THE DURATION OF CHARGING ??? As I said, whoever came up with such a DUMB idea ???

[@rahilbeg2017]

Pls make android phone pcb pls my request my brother

[@remcobooy9837]

Is the schematic some kind of Slayer Exciter...it's looking very simular to it.

[@prebin4411]

Pls... Is it working one.....

[@oniruddhoalam2039]

6:24 We have to take the breadboard parasitic capacitance into account.

[@kspec2001]

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.

[@Handles_AreStupid]

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.

[@llIIllIlIIllX_XIillIIllIIllIll]

>>>>>>>>>>>>. wait I have a question. >>>>>>>>>>>>>>>> 3:55 you turned the primary coil into a magnet by connecting it to AC or DC ? does your power supply generates ( AC or DC ) ? I know the output is AC on the second coil, am I correct ? does the voltage change from DC to AC during the process ?? What would happen if u Connected the primary with an AC current instead of DC ?

[@alpcanokumus]

Hello , I again to sent message email please This subject is so important for me . I saw your wireless charger video from youtube , Everything Ok but i didnt understand short subject , how is your calculate copper coil ??? How did u find 6 turn ??? I think You used to know copper coil information from video , please Can you share copper coil information with me. Thank you.

How much RFI does wireless charging cause to nearby radio receivers in the AM BCB or 3-30 Mhz?

[@wahyupans8868]

I have basic induction cooker circuit like this drive.google.com/file/d/1QYFuaLoJvN3CWtTmfi51sHTgWC3ZNWek/view?usp=drivesdk, but its not powerfull enough, can you modify it?

[@ChessicaLady]

Wow! But if I want to create a induction charger more powerful (in distance), than can lit a 5v led at 50cm, how I should do it?

[@gulshanbajaj73]

Hello wanted to recheck on 0.4mm/0.6mm...What is SWG as in pic wire looks to be thiiner than 0.4 mm. I made with one of the old transformer that did not worked. thickness I am not sure... Pls confirm on 0.4 mm so that I buy same size as new

[@matthewperkins288]

Fantastic video for my high school physics students...

[@thumbwarriordx]

The only other time I've ever heard someone say "Fundament" it was a euphamism for what they were threatening to shove a "very large and very rough carrot" into. This proved ineffective so the ante was upped to a "jacket potato" Someone tell me what show I'm thinking of please, it's killing me lol

Hooks up a cable to usb port: "my phone is charging wirelessly".

[@-ASurya]

I done this project but MOSFET is heat like anything . Why it is heating ? ...plz help me

[@electronic7979]

Very good project 👍

[@ahmedshameem2589]

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?

[@aerohk]

Why wasn't it popular 10 years ago? Everything seems very basic, what was the technology enabler in these couple is years?

[@herobrine1847]

I wish you explained the transmitter circuit in detail. It’s not at all clear why the coil is center tapped, why the mosfet switches on and off, what all the capacitors are for, etc.

[@JVQ8887]

when I place a coil with a load on a commercial charger. Why is this not detected while a compatible receiver is? because there is a load, so would the frequency decrease?

[@bktechnologies88]

Please Mr electronoob you didn't specify the voltage of each capacitor you used please send me the voltage of each capacitor

[@awdhootkanawade]

My phone don't have separate board for USB and traces on motherboard are ripped so am on wireless only mode 😢😢 purchased same charger

[@tribuicang9583]

Very wonderful video, however i have a question: how do you calculate the number of loops you'll need?

[@notyourmomyousnowflake3533]

its directly proportional to the inductance value.

[@ddeeps9041]

Hey ...Is there an AC input given or DC input given here as input. Please someone answer...

[@Umangpatel-np5xm]

Bro can i use 7805 IC INSTEAD OF LM1117 ????

[@Brassmonger]

How do I bypass the standby mode of commercial charger and use it with any coil.

Can I make my one wireless charger cord for something like an Xbox controller or maybe an electric razor or hair trimmers

[@mohamedabdelrehem7698]

a super noob question we use 5v DC not AC right and when we use coil as magnet was DC too??

[@vakgeheimen767]

Some one who undersand this good? can you help me if i want to have bigger and more loops?

[@Techn0man1ac]

Я бы вместо AMS1117 взял 7805, у последнего рабочее напряжение до 35 Вольт.

A Great 0.41W wireless charger that will fill your battery in 40 days, at least.

[@SegunAjayi-vl9zh]

I need clarification, is it direct current,here in Nigeria,it is 230v

[@Tarnished_soulAK]

Whats the use of the other capacitors and the registors in transmission circuit??

[@SsebunyaCollax-kr9sj]

It's nice can you please help me explain how an inverter works cuz you are really nice

[@berger3548]

could you explain or make cut off circuit for battery when its full?

[@kabandajamir9844]

Please explain more about smd down

[@Enthcreations]

This shows that magnetic fiels generate electricity, not the travelling of electrons.

[@Ampereg_17]

Why led on coil is steady, I thing it should blink, because of ac voltage.

[@userou-ig1ze]

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

[@ultralaggerREV1]

Make bigger coils and make them charge a phone from a farther distance.
