Pretty good idea except for if your using it as a spy device, They might notice a laser being shined in their window! Also, I wonder if a green laser would be more effective than a red.
@achemachew why would a green laser be more effective? your eyes are just more sensible to green light, it would depend on the sensor, and you probably can do this with an invisible IR laser and an IR sensor, just switch those two pieces :P
@achemachew yes, take the crystal from the green laser and use it , although it would probably be cheaper if you use a cd reader laser and some lense, I don't know... green lasers are cheap these days
This type of crap makes me choke.. A cadmium photocell is a resistive type device. Most recording devices need a voltage input which this photocell wont provide. I saw this video a long time ago and wanted to slap the fools who made it. It's total bs information,,,
@Redpulsar2011 lmao the voltage input is from the computer , their is co microphone , the photocell is the sensor whitch pics up the vibrations from the laser bouncing back from the window, thats where you hear the sound
I also tried using TWO lasers to intersect both lasers so I wouldn't have to worry about the reflected laser. That didn't work, either. It was fun trying it.I could feel a surge of adrenaline just before it became obvious it wasn't going to work. Anyone know what I did wrong? And I used a good pair of Koss headphones and held my breath as I listened with all my might. NOTHING!!!
sure said REFLECTED laser was spot on the face of said cadmium sulfide receptor. AND I used BOTH sizes of said cadmium sulfide receptors which came in the Radio Shack sampler pack. When I placed both of said cadmium sulfide receptors next to one of my l.c.d. monitors, I got a steady tone. I also received a steady tone when I shot said laser directly into said cadmium sulfide receptors
inserted said jack into a female/female stereo coupler and inserted said coupler into the male TRS jack end of the stereo patch cord and then inserted the other male stereo TRS jack of said stereo patch cord into the "line in" input of said sound card AND during the SECOND test into the "microphone" input of said sound card. The reflected laser was diffused as realistic conditions would be. Nothing happend. I was VERY careful to make
I tried it and it did not work. At all. At a distance of 30 feet I propped up an 18 by 24 inch rigid plexiglass pane and set my radio to Dr. Laura and placed the radio CLOSE to the pane and it even TOUCHED the pane. I could feel the vibration when I touched the pane. I used my Windows XP running a Diamond sound card and used a stereo patch cord to which I connected the cadmium sulfide receptor to a male monophonic TRS jack and
I found this in the back of a magazine once and always wanted one, but from the way it made it look, the laser and receiver were both built onto the same tripod. Do you have to have the receiver set to catch the full reflection of the laser for it to work?
only if we had the infrared laser the cia uses , im sure someone is going to see a red light ,

are there different types of photocells or just one??

couldnt you use an infared laser light thing to make it so people couldnt see were your pointing it at?

@Aqlor Agreed. I could just take the IR filter off the green laser pointer and have an IR laser. You can't see IR except with a camera.

wht u guys could do is instead of a photocell use a small solar panel
hellkid94 2 years ago
The lazer emits the red visible light, so you won't be able to spy on anyone without running the risk of being discovered. Am I correct?
Breal191 2 years ago
@Breal191 so you use an infrared laser--just makes it harder to position the beam on the photocell (but that's what digital cameras are for)

@562135 False!! There is a voltage in the microphone input. Take a volmeter and try before slap somebody! ;)
