This is super legit. Thanks for sharing!!
Amazing video!
If the power source to the transmitter circuit is an AC source such as I am plugging it into the wall to power it, do I still need an oscillator for a switching circuit for the transmitter since I do not need to change from DC to AC for the receiver?
can you show me what components you are using (which wire, capacitor, resistor, diodes etc.)?
The calculations with the corresponding wire?
Great vid!
Hey man, I have similar project for school do you think you could help me a little, I know this a bit of stretch but I’m struggling a little bit to get the voltage high enough on the receiver side.
What if you generate a square puls with a microcontroller, an ATTiny for example ?
It works internally with 8 MHz.
But the puls frequency would be much lower, I guess. ( ??? )
Should it work ?
With a single coil ?
Hi can I have your help I want to ask you some questions about the components you used if you don't mind
Hie can you help with the specifications of the resistors, capacitors, and the mosfet
Does mm matter for charging speed? Is it problem if i have 3-4mm ti the charger
Hie.I have an emergency question.What kind of oscillator is it on the transmitter circuit???????????
Hi Michael, i wanted to ask, i want to build a wireless charger for my samsung smartwatch 3 but i dont know how to build the coil. I found a production site but i dont even know what i need to tell them so they know what coil to build for my samsung smartwatch 3. Can you help :3?
Thank you!!
The power going inside the Coils is AC ? And what is the Voltage of it ?
Hey Michael, so what would happen if I had a greater diameter and a greater number of turns in the transmitter coil? Would that in crease the distance and voltage in the receiving coil? Thanks Michael!
Yes! Your coils would be capable to produce more flux hence greater magnetic coupling. One thing to realize though is this means an increase of the inductance and therefore decreasing operating frequency, which could be a good thing too to avoid skin effect. You trade-off the space for the performance in the end of the day
Why did you use a DC supply and then convert it into AC through the oscillator? You could have directly used an AC supply? Is it because of the frequency and higher voltage level?
amazing I am also working on that
I would like to pick your brain on this. How do I reach out? Curious about shielding for interference. Need a wireless charger for a esp32 BLE project I’m working on that also uses analog sensor.
Oh you're using an ESP32 BLE? I have one of those! Yeah I'd love to help! You can reach out via email michaelnasante@gmail.com, and from there I can give you my discord or whatever other messaging platform you prefer!
Thank you so much 🙏... You explain the circuit very well... It would be appreciated if you can share the components values as well...
I made one referring other TH-cam channel... I used my battery eliminator ... As power supply also use LM317 regulator... But circuit didn't work at all... Perhaps the circuit might not be proper... Now I will use your circuit hopefully it should work... Once I receive the components values
Thanks! I believe all of the component values are already in the video on the whiteboard, but honestly they don't matter too much as what's most important is the input voltage and the components you are using
i have a project about manufacturing a wireless charger and didnt know how to go about the components needed
1- is this copper wire or coil wire?
2- how many volts and how many current are you giving to the transmitter circuit?
How can we use AC power supply in that circuit?
The Capacity value for all circuit is 10nf ?
Hey, certainly I'm doing a project about wireless charging roads and I just wanted to ask some questions. About the form of coils, is the geometries of it affect the charging process ? And what type of coil are the best for charging electric cars
hello there how are you doing
i need your help regarding this project
How do I increase the distance of transfer?
Nice video Michael. However I noticed you said at 13.00 that when the turns ratio increases the current increases thereby there is more voltage on the coil. That is simply not true. When you increase the turn ratio current actually decreases on the secondary coil since the power is same in the both coils and P = VI the current and voltage are inversely proportional. When you have more turns on the secondary voltage will increase and current will decrease
my phone supports wireless charging
so reciever circuit is done
but i want the transmitter circuit to be fed with 220V 50Hz
so what should be the voltage and frequancy be on the coil ?
That's evil
Hi, can we use without center tap for transmitter coil ? and how can we connect to the circuit without center tap coil ? Please answer the questions.Thank you.
Yes, you can use it without center tapping the transmitter coil! However, I wasn't able to make it work without center tapping, but I know it's possible. You could just exclude that portion that involves center tapping and I think it might work. So just remove that capacitor and completely ignore that part of the circuit.
I have a doubt..what is the use of those capacitors
Hii sir, as resource mentioned in description named site as electronics hub, I'm not able to understand why they use 2 coils(L1,L2) in the transmitter circuit. Please help me to solve this doubt( anyone can)😇
So some sites refer to L1 and L2 as the receiver and transmitter, but I think in this case it's referring to them as actual inductors
Thank u man
Isn't the frequency of the transmitter to the receiver also very important..
Yeah it very much is, but unfortunately during my research, I couldn't really find how to factor that in. All I knew is that the frequency does have to be fairly high, and it needs to be filtered with resonance, so that's what I ended up doing.
I am thinking of building one but my project casing is aluminum. Do you think it will work fine?
If aluminium is between the coils, it probably won't.
I liked to design a chess set that ight up the chess pieces wirelessly. Can you help me design it? I am a handyman with little knowledge in ekectronic. Thank you.
Good video
Hai sir... Can i know the current rating when the voltage was 2.7v..that is, during the first testing(1:2 turn ratio)
Same question
The current was around 50mA for a 2.7v rating. I think there could have been better ways to make that more efficient and output more current.
@@N4Prs Thanks a lot 😃
What is to be material used
THANK YOU
Can you share circuit diagram on the breadbord ? is there one capacitor on the receiver circuit?
The circuit diagram showed at the beginning of the video is pretty much the exact same on I used. The capacitors in the receiver circuit aren't super important, you can use 1, 2, or 3 and it won't make a huge difference unless the voltage at the receiver circuit is really high. I was only using 1 in the video because I didn't really need any of the extra capacitors, but it would've worked the same with them.
@@N4Prs Thank you so much
@@N4Prs I am designing a wireless charger ,would appreciate your input and also if you have any valuable info to share with me.
Circuit design and all value of the electronic component. My Email = nuri.ylmz33@hotmail.com
@@N4Prs what is the name of type of oscillator here????
how could i make the wireless charger which works in 3 meter distance?
3 meters? That's quite a distance! You'd need the coils to probably be at least a foot in diameter
Which transistor you've used in the primary circuit??
I used the IRF540 MOSFET!
@@N4Prs thank you 😊
@@N4Prs irf3205 can i use?
Hi, I am designing a wireless charger and would appreciate your input and also if you have any valuable info to share with me.
Sure! Email me at michaelnasante@gmail.com and I'd love to help out!
Hi michael, I have a couple of questions that I did not found the answer to. Would it be conceivable to have a chat with you, mails, Dms whatever, I really nead those answers for a student project. Great video by the way it lead a major part of this project, thanks.
I tried same circuit with BD139 and IRF540 , both Circuits didn't worked even though I followed same steps
You have to play around with it a little bit. But make sure first both coils are actually transmitting. What I did to test it was to use a waveform generator to verify that, then I connected the coils to the main circuit again. Test out each individual component as well.
@@N4Prs yeah, actually the problem is transmitter circuit is not working probably , I'm unable to access oscilloscope due to lockdown.
@@abhisheksaware4975 Oh that really sucks, the oscilloscope is super valuable in this! But I actually did this project without the oscilloscope, I started it right at the beginning of the lock downs. I used my multimeter to do what testing I could on frequencies. I would also make sure your input voltage is good, I used a 12V input for mine which gave me better results
@@N4Prs I will try again, right now I'm having exams from 11 to 20th May , If you have line id please share it
