Be a Spy with This Cool DIY Spy Microphone

Have you ever thought of picturing yourself being a spy? Doing covert operations and spying on people? Nah, I think you've only seen them on movies, yes on movies, but how about giving it a try, though not professionally.

So I’ve decided to give it a try. One cool thing that most spies used is a spy microphone. I found this cool spy microphone that uses laser. How cool is that, a spy microphone and a laser is too awesome right?

Though I found about this tutorial as not the most practical recording setup we can every used, but it still in an interesting bit of science and a great DIY Project.

What’s so cool about this thing is that it will allow you to listen inside of buildings hundreds of feet away from you (yes, I know what you’re thinking, lasers are awesome). The process of creating the device involves a simple bit of soldering and all we will need is a laser pointer, tripod and old pair of headphones, photocell and a recording device.

Here’s a simple diagram of the device. Sorry, just grabbed it from the source.

The output forms a complex signal when an electric current passes through the said diaphragm, which can then be interpreted by a recording device as sound. It can record sound though windows with a laser pointer and cheap parts you can find at any electronics store.
