DroneShield is an indieGOGO project from a DC aerospace engineer that aims to build a tiny, net-connected drone-detector/identifier. Based on a Raspberry Pi gumstick computer, it uses a mic to detect the audio signature of nearby drones, and then communicates about its findings over the Internet. The project promises free/open hardware and software specs on its main site. Ars Technica's Cyrus Farivar spoke to Chris Kyriakakis, a USC electrical engineering prof, who suggests the project is feasible, but believes it will need an array of mics for accurate identification. But John Franklin, who's running the effort, says the device will produce useful -- if imperfect -- output even with one mic.
The fully assembled drone detector costs at least $69 as a pre-order (as with all crowdfunded project, it's important to remember that you may never get your device). The project goal is to get them down to $20. For my part, I wonder how this would perform against active countermeasures: it's one thing to detect drones that aren't making any effort to remain hidden or fool detectors about which drone they are, but what about a drone that uses some technology (from playing a recording of a different drone to full-on modifications of its engines and blades) to sound different?
In any event, I expect that this is an intermediate step on the way to this thing disappearing into our phones and becoming an app that would make use of its open database of drone acoustic signatures. I can easily imagine a Drone Foursquare made by volunteers who upload drone "sightings" to realtime maps as they move around the world.
Meet Drone Shield, an ambitious idea for a $70 drone detection system
The flashlights in our household have a tendency to wander off. Where do they go? I gave my last remaining one to my daughter for a camping trip, so I just reordered an 8-pack of metal LED flashlights for $14. Each flashlight has 9 LEDs and uses 3 AAA cells (included, though some reviewers on […]
Unlike a multimeter, this battery tester isn’t battery powered. Instead, it measures the voltage across the terminals of 9V, AA, AAA, C, D and 1.5V button type batteries. It’s also easier to use than multimeter probes. It’s only $6.61 on Amazon and has a 4.5 star rating with over 1500 reviews.
This handheld magnifying glass has two bright LEDs and is powered by 3 AAA cells (not included). The manufacturer says the magnification is 40X. I think it is less than that, but it is still plenty powerful for my needs – mainly, reading the markings on tiny electrical components and checking the layer fusion on […]
