Meet Drone Shield, an Ambitious Idea For a $70 Drone Detection System
An anonymous reader writes "Here's an Interesting idea of how to use a Raspberry Pi and a few other inexpensive items to make a low cost detection system. From the article: 'The Drone Shield would combine a Raspberry Pi, a signal processor, a microphone, and analysis software to scan for specific audio signatures and compare them against what known drones sound like. (Because obviously a Predator drone is going to sound very different than a small quadcopter.) Once a match is found, the Drone Shield then sends an e-mail or SMS to its owner...'"
So now the highly directional microphone has to be pointed toward the undetected drone in order to detect it? That makes perfect sense.
Hm. That might be interesting. Build a couple and put them a distance apart, plus a remote controlled super soaker. Sit in the basement and pretend it's a sub.
"Skipper, we have a contact on bearing 238... probable squirrel class mammal, likely a grey!"
"Do you have a firing solution?"
"Range and course calculated skipper! Firing solution locked in!"
"Fire!"
"Skipper, sudden change of aspect on the contact. I have angry squirrel sounds."
"Nice job, everybody."
A Raspberry PI is also way more CPU power than needed to do it, which means it can also do a whole bunch of other stuff too.
My ++ model will mine Bitcoins between drone attacks!

Funny will be when they mount these drone shields, on drones. Then the drone shields will be warning you about other drone shields operating in the area.

Sounds like you need a beowulf cluster for that!

You actually don't need to listen for them. If you watch really carefully, you might be able to see part of your neighborhood blow up. Then you know a drone is overhead.
