Listen to conversations over long distances with a homemade laser listening device. All you'll need is a laser pointer, tripod, old pair of headphones, photocell, a recording device, and the step-by-step instructions in this how-to video. The creator of this video tutorial does not mention the need for sophisticated software. But the principle is quite sound. If you can figure it out, you can eavesdrop and spy on whoever.

very very very great idea ! please send more videos like this !!!
woooooooooow thanks !!
that's pretty cool.
Yeah, I agree. Pretty cool
no way i bet your girl fiend love all the time you
spend play around listening to other people
Very nice, but how can you tell if the laser beam is on the photocell in daylight?
wonderfull
The theory this looks great.................
where does the photocell come in in this i couldn't understand waht he said to do with it. something about the reflection of the lazer has to be on it.
coooooooooooooooooooooool
I blinded my parents with this device :( :(
I have a recording of my dad shouting 'f@ck f@ck, my f@cking eyes', then some stumbling noises. I recorded it with my laser microphone and stored it on the laptop my dad used to beat me with.

to bad i wipped one up, and wrecked a perfectly good 3.5patch cord, just to find out it just a bunch of crap
I guarantee you this works. this technology has been around for a loooong time and is used by law enforcement. you must suck at building electronics.
so.... u tried? i want a real opinion b4 i try it
Actually I tried too... it's sketchy at best, all I got were pops and static. Not only that, but getting a decent reflection off a window and having hte photocell pick it up is difficult, over a distance it's virtually impossible. A great concept but pulling it off in this manner basically doesn't work.
I COULDNT SEE HOW TO MAKE LASER MICROPHONE!
good work!
how do i build a tape recorder blocker
I don't know if this particular design would work or not, but it's similar in concept to a design that was published many years ago in a major electronics magazine.
In the very next issue, the magazine was chewed out by an American law enforcement agency (can't remember which one) for publishing the design for an "illegal device" and encouraging their readers to build it.
If you build one and it works, I'd keep it quiet....
Thats really REALLY cool!!
I gotta try this!!!!!
i think the quality will be better if u can amplify the signal from the photocell...
I AM GOING TO TRY TO MAKE THIS DEVICE AND I TRUST THAT IT'LL WORK.
I heard "who the f@ck is playing with that laser pointer outside?"
use a infared laser and adjust it using goggles that can see it!
Hard part is you have to be where the laser reflects too, strait out and just as high up, making this very hard to do unless its the girl next door and your windows are strait across from each others, but for some reason after the lights go out I hear a Buzzing noise? Do you think shes brushing her teeth with a electric toothbrush in the dark in her bedroom?
Nice, I will try this when I have moved, I gues that I can use any mp3 recorder?is this possible?
kewl
Just what every stalker and creeper needs
anyone tried this? please help me building this....

this is bullsh*t. using a 3.5 headphone jack will not work, your not even using standard microphone wire. if they had used a 3pin XLR or 3.5 microphone cable it would have more believable!
Don't try it, youyr money likely to fry you motherboard from putting an input which isnt sound into your laptop!
Umm... No. Headphone jacks are the same as microphone jacks.
The other day I cut the wires on 2 headphones, and used alligator clips to attach the strands of wire in both headphones. Basically I had a cable with two headphone jacks on each end. I then plugged one jack into my iPod, and the other into my laptop's microphone input. I played a song on the iPod, and Windows Sound Recorder heard it perfectly through the "headphone" jack plugged into the mic input.
boring...............................................................................................
shut up spongebob gaypants
what is the little wire of the laser?
I wonder if the photo cell and laser beam off of a garage door opener would work.
