Speakers operate on alternating current (AC), whereas the laser requires direct current (DC). - Modulation and demodulation of the signal require additional components and precise tuning to avoid signal distortion. P.S. The 3-watt amplifier cannot drive an 8-ohm, 20-watt car speaker as this chip simply doesn't have the capability to power such a speaker.
Why did you use only one channel? I would have connected the two channels together in your place so that you get a 6W channel. :) Interesting about your design. Which laser did you choose? The blackboard pointer is reasonably good but I would like something compact but more effective. I look forward to technical advice and comments on this. Thank you very much.
I think this video is quite fake, because I don't think the output of the PAM8403 producing DC voltage to light up the laser diode. The real working things I know is, I did mine with LED light connected in series with a single mosfet transistor, put 1K resistor between gate and drain, 10k between gate and ground, and a 10uF capacitor to the gate from the audio source. So, the LED will light up continuously and will be vibrate or flickering when the audio signal fed into the gate of the mosfet. That is the transmitter circuit. The small solar panel on the other side (receiver) will produce current in the form of audio signal according to the vibration of the LED light thus fed to the audio amplifier and produce sound. That's it.
Yes, in fact a technology for doing so even before lasers existed in the 1890s with the Telediagraph and 1907-1913ish with the Belinograph… it was really perfected with Wide World Wired photo service… basically like sending a picture via dialup internet via telephone, sending photos at the speed of light in the 1930s. We’ve been in the technological age for over 100 years now. Some might even say 150 years. You can send photos via amateur radio as well, even bounce the signal off the moon to get to stations further than line of sight (because Ham radio is VHF)…
درود. شما مشکل دیستروشن صدا نداشتین؟ من نتونستم صدای خوب و قابل استفاده بگیرم. مثلا میکروفن که وصل بشه صحبتها قشنگ مفهوم نیست. ممکنه به شکل موج اون صدا ربط داشته باشه.راهی پیدا شه میگم.
@@skillmake theres a project to making that..but it still used wires to speaker from hub to split channel..i think you can make better than that, i dont know how to split frequency or line by bluetooth..keep the great work.

An Arab man did it 3 years ago. Nice project
Goodddd!!!!, i do this when i was kid

Hi Skill Make, what about the current spec for the 5-volt input, if we do not want to use battery.
Nice job congratulations 😊
Laser, this: " Green line laser module 532 nm/laser diode/light-free driver/LABORATORY/WorkiDO stable " ?

Video is probbably fake, but it is quite easy to send information with laser
No it's 100% real .I did with LED as a transmitter and solar panel as a receiver .IF U want to transmit audio for long distance we want to use LASER
Is it possible to send image like this?
Video amplifier and camera?
Yes you can
Yes of course bro ,
You can send pretty much everything in theory. That's how internet in transmitted between continents under the ocean.

Could you share more technical characteristics of solar panel? For example, the exact voltage and current, please
Maybe that's form of energy transmission, Idk. If you would do video converting sound into light, that would be cool.
Nasa had made laser communication which is used to transmmit signal's in space

why did you use 3.7V battery on a 5V amplifier
There is no 5v battery
PLEASE TRY AUDIO TRANSMISSION WITH MICROPHONE ALSO TRY TO TRANSMIT VISUAL DATA BY USING LASER TRANSMISSION
That's crazy bro
Bro what range of supply are you giving or what voltage of battery
بسیار عالی مهندس
please do this again but instead of audio please use 10Base-T Ethernet.
How to purchase Circuit board
AliExpress ?
Hi..im your new sub..i like your audios project..
Can you make 5.1 or 7.1 by bluetooth transmissions 🤔..keep up the great works..tx
thanks for idea i will try
@@skillmake theres a project to making that..but it still used wires to speaker from hub to split channel..i think you can make better than that, i dont know how to split frequency or line by bluetooth..keep the great work.
Can you post Circuit diagram

Very nice 👍

Can it's transfer video
no it just for sound
love this
hey i had this idea !!! good job man....
It's a little like li fi , isn't it?
Sound is not good why?
Nice I will succeed
you jenius bro🖒
oh thanks
nice magic
bro make toslink optical
Perfect bro⚡

Making it look complicated, though.
