Low cost project. In this video i show you how to transfer sound over light!!! Yes this is possible! I transfer a sound with distance of 5 meters. But you may experiment on greater distances.

this is hands down
one of the best videos I have seen on metacafe. Ultra cool experiment! 5 stars! Looking forward to more videos from you.

Photoresistor
What if I used a photoresistor instead of an opto-transistor. Will it still work

nice
but do you think is there another way of transfering the sound ( the sound appears when breaking the laser beam, just like laser security system)

terriost tactic
this could be one way a terriost can communicate with others without broadcasting everywhere like radio signals. only the reciever the laser is pointing at can intercept the signal.

- Yes
  Yes. But have some problems. They can lose signal on rain, snow, fog etc.

hi
can the receiver be just a speaker? i mean connect opto transistor to the speaker jack?

- To low...
  I try this with 6 Volt battery in serial with opto transistor and earphones. It`s work but sound is to low.

- No...
  Maybe if you connect battery, serial with opto transistor and speaker. I will try and then i will tell you.

At The End
Notice at the end when he waves his hand over the chip, the sound of the lights around him, cuts in and out. Forgot what that's called, but that would be interesting is to build this at a portable and hear what sound different lights make.

question
the receiver is the opto transistor connected to where? speakers plug?

Thanks to all
I'll try the next experiment to be as good or even better

Thanks again

is it just me...
...or does it look like he plugs that into the green (output) plug?

I will show this to my son!
so he does this experiment at school ;)

thanks for giving me an excuse for spending time with him :)

light dependent resistor
can we use a light depended resistor instead or opto transistor or opto resistor
By uarsalan 1208470190 Reply Spam [-1] Moderate Up Moderate Down Remove ~~5983278~~
- 0
- Probably...
  I think yes. As i know light depended resistor is another name for opto resistor. Thanks

need some help
Is The Opto Resistor The Same As A Canmium Sulfidfe Photocell, If Thats The Case Then I Tried And It Wont Work I need Some Help

- Hmm
  I haven't tested with Cadmium Sulfide Photocell and i don't know what to tell you.I think that with photo transistor you can get the best resultat. Thanks

Be careful
Don't use mono jack, use stereo jack but only one connector, because if you use mono jack with stereo jack on your PC like on this video you can burn one audio chanel, because one chanle is short circuited. If you look closely mono and stereo jakc you will see what I mean.
