Long Distance Laser listening device

the following project will show how you can use a laser pointer to hear noises from hundreds of feet away (the distance will be relative to the strength of the laser).

Step 1 Materials

We need
1. a laser pointer
2. a old pair of headphones (mic cable with stripped ends)
3. cadmium sulfide photocell (avaible at radioshacks)
4. 2 Tripods
5. A computer with audio recording software

couldn't you do it with an IR laser (provided you have the tools necessary to align it with the photocell)

did you just google 'laser project' and think this one was the easiest?


I did that then made something better cause they would catch me out....
