Long range wireless control of a project is always a challenge. [Mike] and his team were looking to extend the range of their current RC setup for a UAV project, and decided on a pair of Arduino mini’s and somewhat expensive Digi Xtend 900Mhz modems to do the trick. With a range of 40 miles, the 1 watt transceivers provide fantastic range. And paired with the all too familiar Arduino, you’ve got yourself an easy long range link.
[Mike] set the transmitter up so it can plug directly into any RC controller training port, decoding the incoming signal and converting it into a serial data package for transmitting

The liability damage and personal injuries from small, fast-moving unmanned civilian vehicles can be huge–and more and more often will keep the Federal Aviation Administration, lawyers, and all of us on high alert.When a regional triathlon in Australia hired a local drone operator, Warren Abrams, to take aerial photographs of their event, competition organizers of course never expected serious injuries from the UAV. But one of the event’s triathletes is now in stable condition in the hospital after receiving head injuries from a drone collision last week–and the athlete, organizers, and the cinematographer are arguing over whether the athlete was hit by the drone or not. And while this case might seem strange, it raises an important question–who’s responsible when commercial drones hurt people?Read Full Story
