I find it interesting the song you chose to play.

Shining an IR laser onto a DISTANT window an aligning the return beam with the detector is useful ... any sound in the room ( talking ? ) will vibrate the glass ( modulate the light ) and can be heard in the audio output device ... DAVE™🛑

awesome job. Personable, succinct delivery of data, Floyd as the demenstrative media, an excellent choice especially for gaining non science interested viewers . Iam actually interested in how tosend data wirelessly thru light, and how to defend against laser microphones.

Nick, I would like to make a system that could transmit and receive from car to car. The laser would not need to be precise but mounted on the front and rear bumpers of the two vehicles. Transmissions would be limited to line of sight--very private compared to CB radio.

Which laser has been used in this model?

[EricPham-grpg]

Echo sun light amplified can be as strong as 10, 000 wat laser easily and use moon reflect back

[ericphantri]

That is why magnetic dome from sound use sunlight for broadcasting smartphone but laser are separate channel reserved..thanks

[ytchess]

How dangerous the lasers are? Can it harm nature, the earth in any way (long term)?
