How to Catch an Evil Drone

"ON APRIL 22nd a drone carrying radioactive sand landed on the roof of the Japanese prime minister’s office in Tokyo. It was the latest of a string of incidents around the world involving small drones. Last year more than a dozen French nuclear plants were buzzed by them. In January one crashed on the White House lawn. In February and early March several were spotted hovering near the Eiffel tower and other Parisian landmarks. Later in March someone attempted to fly one full of drugs (and also a screwdriver and a mobile phone) into a British prison. The employment of drones for nefarious, or potentially nefarious, purposes thus seems to have begun in earnest. It is only a matter of time before somebody attempts to use a drone, perhaps carrying an explosive payload, to cause serious damage or injury. The question for the authorities is how to try to stop this happening."

Yeah, yeah. New technology is going to destroy society. Have we heard that before?  Of course drones can be used for bad as well as good. Every leap in technology from fire to the printing press to drones is capable of good and bad.  We should prepare though, as this article is showing, to counter the nuts who misuse drones.

quadcopter investigates crop circles in Russia

http://rt.com/news/266719-crop-circles-drone-footage/

"Puzzled by the “alien patterns” in a wheat field in the Republic of Adygea earlier this week, local residents sent a drone to investigate the series of mysterious crop circles. Meanwhile similar shapes have also surfaced in the Moscow region."

As I understand it, you don't want people walking around in the crop circle before it's investigated, so they don't spoil the evidence of how the crop circle was created. This one looks like people actually walked around in it while it was being made!

DJI adds some great features to new quadcopter

http://www.gizmag.com/dji-launches-developer-focused-matrice-100-drone/37933/

"So perhaps it was just a matter of time before industry heavyweight DJI came to the party with what it claims is the first commercially-available collision avoidance system for drones. Guidance relies on an array of ultrasonic sensors and stereo cameras to detect when the drone flies too close to objects, with this range configurable and can extend to 20 m (65 ft)."

"Ready to fly out of the box with dual battery slots and a whopping 40 minutes flight time, the Matrice 100 features several communication ports, power supply leads and expansion bays for extras components, so that additional hardware can be fixed to the drone to afford it new functionality. "
