On Tuesday, an ambitious aerospace engineer from Washington, DC began seeking donations on Indiegogo to create an open-source drone detection system.
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. As of this writing, the campaign is only closing in on one-tenth of its goal with $301 out $3,500 raised.
John Franklin, the projects organizer, believes it would cost around $60 to $70 to make one, but hes hoping to raise funds from other privacy-minded citizens like himself. He notes the idea here is to counter the rising use of drones not only on foreign theaters of war, but also in domestic skies.
"I'm a problem solver and I'm trying to gauge if this is a problem that people are interested in solving, he told Ars. The idea here is that it becomes an open-source thing and people could contribute their own signatures.
Franklin estimated it probably would take about $100 and two months to figure out if the idea would work. There are other anti-drone tactics and devices out there, but none quite as cheap as this oneassuming it functions as advertised. Not all experts are convinced.
