I am not an electronics person. Attempting something similar to a laser espionage microphone, but for a fun event. It is a very basic set up. Laser pointer pointed towards a mirror at Home. Playing music near the mirror. The reflected beam is picked up by a solar panel or LDR going into a recorder. I tried feeding that solar panel's output to a Marshal MS2 guitar amp, but it does not reproduce any sound - just get a buzzing noise. But when I connect it to a recorder (smartphone or computer) and record it, interestingly it is able to get my voice when I make a loud noise, but not the audio streaming or any regular noises around .
All the DIY videos make this look so easy - Does this actually work? Sincere apologies if this is basic (I suspect it is) Any help would be appreciated.
