    I don't think this would work. You need modulation to send the signal down the laser. The audio transformer can be bought online from Radio Shack or from https://www.hammfg.com/electronics/transformers/audio

    For anyone and everyone who has or will as “What type of audio output transformer did you use?”. He used a Audio output transformer, 1kΩ primary coil, 8Ω secondary RadioShack part #273-1380 or Scitoys Catalog #XFORMR

    can i use photoresistor instead of the solar cell??

    Is there any other suitable substitute to the transformer?

    Hlo sir im vinay
    I saw this vedio and thought of making it as my mini project
    As im an final year engineering student could u plz send me an abstract and soft copys to my mail id

    Very beautiful themes, but it would be nicer if developed scheme at the end of each film and thank you

    What is the input and output voltageof the transformer

    ahhh so this is how optical cables work. or not

    Can it it be converted or changed to transmit data like video or text

    wasn't the transister ECE 4760 SOMEBODY HELP ME

    plz tell me where should i get an audio transformer

    Hi, I'm currently studying physics and this is a new area for me. I'm wondering what purpose the transformer fill and how it works. I'm only familiar with transformers that changes the voltage in ac currents (for example converting to higher voltage when transporting electricity)

    After the first seconds of the video, I was thinking about some transistor-based circuit for modulating the laser beam. But doing that just with a transformer was really a brilliant idea. Thumbs up!

    nice project can you do it with AV?

  21. Mateus Bueno

    April 16, 2018 at 6:11 am

    How it works? Can you explain?

  22. Tatar Sergiu

    How the hack are you saying that using a solar cell you get audio signal ???solar cell gives you DC,to have audio signal you need AC! don't prank people to get money!

    who is watching this in 2016

    The old film projectors used the same light that projected the picture on the wall to also make the sound that you heard. If you looked on the sides of the old films you would notice little black like wave patterns. When the light shined through this wave like pattern it would make the sound that you heard while watching the film from one of those old film projectors. Great video

    How far can the signal go? E.T. Phone home.

    Can I just buy a walkie talkie and add a laser?

    Is there a replacement for the solar cell??

    I wonder if I could do something like this with a stereo receiver have wireless speakers

    what kind of audio transformer we need to use,please tell me.

    Can I use a transformer from a radio?

    Instead of the Lazer and solar panel could you use an ir transmitter and reseaver? Just out of curiosity.
