- Here we will do Data transmission experiment by using Li-Fi. Maximum speed of Li-fi is tested 100Gbps and it can be upto 240 Gbps theoretically. In this experiment, we will transmit audio signal over Li-fi.

Parts used:-
1) Solar panel
2) Light
3) Audio Amplifier Board
4) Speaker

Since this project using light works, my idea of advancement to use this would be to couple a micro light receiving plate and a 1mm optical cable that can channel the light from the device to the headset without loss, thus replacing the cables copper that eventually break
Thank you for your idea. Definitely I will try

If you want, go to my channel and see, I just posted a video demonstration of a plastic optical fiber, this type can be used for the Li-fi project!
Good one nice
Awesome
It’s fake. First of all it can’t transfer 150 gbps . Second at 5:30 when he put his hand in front, he touched the phone and the phone went to the ncs channel and the music was still playing.
Saw it too.
You connected a solar panel to an audio amplifier what function does that serve, and how did you arrive at the figure of 150 Gbps
because thats the speed of light and speed is not 150gbps but actually around 10Gbps, thats how optic fibre works.
Can this effect be achieved with infrared light as well?
The audio amplifier was to amplify the voltage received from the solar cell, in order to drive the speaker.
We can use 5 volts solar panel also for this
Can we used 12v solar pannel
Very very very nice 👍👍
Where can we use this lifi project in daily life
Super
Another input ports connected to what sir
WOW!😯😯😯 This is really ridiculous. What a simple piece of technology!
Anyone notice during he play song his song is off in you tube then how it's possible
Bro can I use blue led
which type of led do you used
Plzz reply
Normal led
Sir if it will not work so can u suggest some different science model related to these things
why we can't connect an usb 3.0 pin and an micro usb and transfer files from one mobile to another mobile???
What voltage of solar panel is needed?and can i use calculator solar panel to make this project?
You can use any solar panels . But use great than 3v solar panels
Can I use calculator solar panel?
No
@@creativefield6302 Thanks a lot sir
Sir.. what is the speaker wattage to be used.
When i am using 1W solar panel ?
Plzz do reply....🙏
And which LED to be used..? For 1 watt solar panel...
Please do reply soon..
I invested money and i am not getting o/p..
i have 6 volt panel and i use bt speaker or any other 180 rs speaker will work (wired mini speaker) wired one is o ubon and wireless one is of boat
Can I use 5v speakers
I completed this project long back...
I used :
1W solar panel
4ohm speaker
MAINLY : PAM 8403
Normal LEDs at transmitter side
9v battery at transmitter side
5v battery for PAM8403
Sir where you connecting that 5v charger.plz rply
can plzz tell me how much time it takes to send a file completely to another device in ( bps)
Google "fiber optic broadband" to find if out.
@@whateverittakes4345 That's not Li-Fi. That's just plain fiber optic transferring.
Thats the same
sir i made but i tried with 4 phones but 4 of them did not recognied the headphone jack. sir please reply tommorrow is science exhibition
Try to use another aux . Hope for best
Sir will the phone speaker will produce sound ?
THANKS FOR THIS ONE AT ALL. I NOW KNOW THAT 😊😊
Iska use kider hoga??? Kya sirf audio hi transfer hoskta h???????
No it is used to transfer data also, please see the TED Talk carefully.
Can I use 5v speaker
Sir what is the current in speaker part
Can i use hiv battery which u used in LED part ... please reply it is very urgent
No you can't use 9v battery in amplifier , 9v battery burn amplifier
Nice it is working ! I thing so
Sir can u plez give me the circuit diagram for solar panel side and Mobile side also plez sir...plez .. I need it on day after tomorrow my exhibition is there plez sir .. do fast
Ok
Contact me for circuit diagram on creativefield9@gmail.com

You can use small led for 1w solar panels and check wiring will testing
It works thanks
Please specify the components you used...
Damn urgent..
@@sharathkumarhk4260 watch detailed video on my channel
@@Freakengineeryt I completed doing that 9 months ago.. thanks for recommending.
This is not how internet work.
Its looks like a switch but a fake switch
Bro is it work really
Press the 'M' key and feel better
Where will we get amplifier
On Amazon or offline store .
In a coffee shop
😁😁😁
Using laser would have been better
Can u plz tell me all the values of these devices e.g solar panel 3v etc
You can check online or offline for price
Light is working but voice does not working
Sir it is not working , I used the speaker of 8ohms and 0.5w and 9volt battery
Sir use amplifier
Sir I used
Use minimum 4 ohms 3w speaker and check wiring
It works
Without audio module can it possible to it?
Bro are u sure its not fake.... Cause already we have tried lifi by another RUclipsr but it didn't work
Bro this is not fake .
Check wiring of you project
Wow my mind is blown! and I'm not even here as Scientist! I was wondering if anyone could tell me how this experiment works? Like what is needed for the data to be sent via light and for the revieving component to process that data and output it?
Not data
Only wireless power
It's work
Electroboom
It works!. But i used very different battery. 3.7v samsung battery.
Hi Orlando, could you describe your experience?
But voice is low
If you want louder sound use powerful amplifier
This can work, especially with a powerful laser and a lot of tweaking.
And theoretically it could go MUCH faster (100Gbps proven by science), but the reciever would have to be absolutely foolproof, so a few missed strobes would not cause much trouble. While a few lost flashes wouldn't be a problem (afterall, this data loss sometimes happens even on direct wire connections), interference from AC bulbs would be a huge problem. So if Li-fi becomes a thing, you won't be able to cheap out on LEDs, use incandescent/CFL bulbs or use dimmable LEDs (as long as they don't have a dimming circuit of their own switching at higher PWM frequencies like 50 kHz or more).
Sir this project in not working
My channel has a good explained video on how to make it.
Tell me problem I am trying to solve it
Please sir help me out plez....plez...plez......
What is the problem?
See my chaneel
it use a roll off cofficent of 0.2 and NRZ of course? Oh by the the way gbps mean digital transmission lol.
keling
Sir it is not working
In next comment you added.. it worked.. what changes you did??
Plzz do reply...
Sir please help me out
Sabkay sab cutiya hey yaha dekkho thikl say video he band horahahey direct fur bhi kaise chal rahahey sound
Lol
It is fake. I mean this guy isnt even soldering his darn wires.
Edit: I should add a disclaimer. This is of course not Li-Fi, it's more like a terahertz AM radio, the description is full of bs but I have to admit it works:
I honestly hate to say this but the video is not fake. Basically the LEDs are biased at 9V(way too high and might burn them) and then the audio signal raises or lowers that by less than a volt. This produces variations in brightness that aren't very noticeable but they produce variations in the solar panel output voltage. The amplifier filters out the DC component caused by ambient light and the 9V bias and leaves only the variations which it amplifes.
Now before you say that there is no way this would actually work. I just tried it myself. However I added a 1k resistor to the LEDs to stop the current from frying my phone. And as an amplifier I used a small portable radio with a Line In input. The music quality was surprisingly good but the range was very low.
@@seeeyes12212 Thanks, fixed. Lost the heart though :)
chiya banrya lodu
You cant transfer 150Gbps with LiFi clickbait
Did you really need that stupid music ?
That was a fack project
wtf ....it works ahh ///without a microcontroller????......GO TO HELLL//.....lol
