I can build it for $20 -- the government will still spend $1,000,000 ... gotta love it

The only problem is that not only the sound IN the room is bouncing back from the windows, also street noise...

No one notices a laser beam shooting through their window? lol

bullshit!

I doubt it would work with this cheap gear. And even if it worked like that, you'd run into problems:

The angle of incidence very much limits were you can put the receiver relative to the laser.

Furthermore you'll need a infrared laser pointer in order to not be noticed.

Then you need a camera that can see infrared in order to aim.

(And this is just from the top of my head)

@ironclad452 But yeah, the gubment is totally stupid, if they can get something working for $20 from you…

@boekelnj

They spelled it "Candidte."

[boekelnj]

@MrPatrickHenryCheryl Meaning he's in the process of obtaining a Ph.D. If you're a candidate, it usually means you've passed qualifying exams but you still need to finish classwork/your dissertation.

"Ph.D Candidte?"

@webnut2000 this is false: the receiver captures back the feedback of the laser which is not biased by the other noises because the laser here acts kind of like a sonar or an ultrasound.
