DIY Laser Communicator Sure to Create Wannabe Geek Super SpiesS

This handy DIY laser pointer communicator requires little more than time, an old laser pointer, some parts from your local RadioShack, and, of course, a tuxedo.

Here's the PDF file (eyes only!) you'll need to get started on what actually sounds like a pretty neat little 15-minute project.

Basically, the audio signal from the attached microphone varies the power output of the laser. This, in turn, causes the laser's brightness to fluctuate in a way that follows the shape of the sound wave.

At the other end, where your super spy friend awaits his kill order for those pesky neighborhood revolutionaries, a solar cell (or photo-resistor) helpfully converts the oscillating light signal back into the husky, absurdly fake Scottish accent you've applied to your voice in yet another lame, cliched attempt to mimic Sean Connery.
