Has the Do-Digicam-Control issue been resolved? Haven't been able to find any updates about it anywhere. It would be great to fly automatic waypoint programs and have the APM take pictures at the waypoints.
Thanks!"

Welcome to DIY Drones!
This is the home for everything about amateur Unmanned Aerial Vehicles (UAVs). Use the tabs and drop-down menus above to navigate the site. (About us/Site rules)
This community created the Arduino-based ArduPilot, the world's first universal autopilot (planes, multicopters of all sorts and ground rovers). The APM 2.5 autopilot hardware runs a variety of powerful free UAV software systems, including:
- ArduPlane, a pro-level UAV system for planes of all types.
- ArduCopter, a fully-autonomous multicopter and heli UAV system.
I'm new to all this--where do I start? Are amateur UAVs legal? (yes)

Last week(week 5) I tested out a new FPV system using 1.2 GHZ. It works great. The only problem I had was that it was locking out my 2.4GHZ control. So for the video I used my old 72mhz radio. Let's just call it glitch. It glitched me right into a patch of stinging nettles. So I ordered a low pass filter from Readymaderc.com. Then I commenced to building yet…

Survey Copter Flies To Stratasys For 3D Printing Of UAV Systems
France-based Survey Copter, a subsidiary of the European Aeronautic Defence and Space Company N.V. (EADS), specializes in the design, production and integration of complete remote systems for surveillance photography and video service applications for UAVs and other airborne craft, as well as for sea and overland vehicles. Having previously outsourced its prototyping requirements, Survey Copter turned to Stratasys for an in-house solution that could reduce costs and ensure greater efficiency and autonomy, granting the company the means to rapidly produce very small quantities within 24 hours. Via Stratasys’ French distributor, CADvision, Survey Copter subsequently installed two 3D printing solutions – a Stratasys Dimension Elite 3D Printer and Stratasys Fortus 400mc 3D Production System, which offers nine production-grade engineering thermoplastics using Stratasys’ patented Fused Deposition Modeling (FDM) technology. “Effectively meeting our 3D printing needs can only be achieved via machines that are capable of producing quality parts with high reliability,” explains Jean Marc Masenelli, managing director, Survey Copter. “Stratasys’ reputation for delivering 3D printers that meet these criteria head-on made them the logical company to partner with.” Spearheading Survey Copter’s prototyping and short-run manufacturing activities, the Stratasys Fortus 400mc and Dimension Elite 3D Printers are deployed in the production of component parts for the company’s mini-UAV [...]
Aeryon Labs Announces the Aeryon SkyRanger sUAS
WATERLOO, Ontario (May 23, 2013) – Aeryon Labs (www.aeryon.com) launches the Aeryon SkyRanger™ small Unmanned Aerial System (sUAS). This new Vertical Take-Off and Landing (VTOL) system features an all-new airframe and integrated design, and represents a significant leap forward in capabilities for military, public safety, and commercial applications. With the completion of extensive field testing and first customer trials, the Aeryon SkyRanger is now available for further demonstrations and orders – with priority to military and government customers worldwide. First introduced in 2009, Aeryon sUAS are regularly at the center of major world events and international media stories due to their reputation and proven track record for immediate, reliable operation in high winds and harsh weather environments – often when other UAS or manned aircraft cannot safely operate. Designed as software and payload platforms, Aeryon sUAS also provide advanced features and capabilities including an intuitive touchscreen interface that provides simple point-and-click navigation and camera control, and seamless automated functions and safety features. The Aeryon SkyRanger™ brings new capabilities to the field-tested and battle-proven Aeryon sUAS platform, which has seen continuous development and innovation since the Aeryon Scout™ was launched in 2009. “The Aeryon sUAS platform is the most mature, reliable, [...]
First flight for Triton
The Northrop Grumman-built Triton unmanned aircraft system completed its first flight May 22 from our facility in Palmdale, Calif. The flight, which was about 1.5 hours successfully demonstrated control systems that allow Triton to operate autonomously. Triton is specially designed to fly surveillance missions up to 24 hours at altitudes of more than 10 miles, allowing coverage out to 2,000 nautical miles. The system’s advanced suite of sensors can detect and automatically classify different types of ships. Bookmark It Hide Sites
Parrot AR.Drone 2.0, ‘Built for the elements’ The movie
‘Built for the elements’ is a non-standard movie filmed in slow motion – 1,200 frames per second – with a high speed Phantom Flex camera. A true technical challenge, it offers stunning images that feature the robustness and the power of the Parrot AR.Drone 2.0, definitely a one-of-a-kind quadricopter! The film will premiere May 22 on www.youtube.com/ardrone. The machine faced with the elements Lighting in chiaroscuro, a black set whose boundaries aren’t visible… The scenery is arranged. The singular shapes of the Parrot AR.Drone 2.0 appear in a halo of light… Its engines pushed to their maximum, the quadricopter throws itself in a mad dash during which it has to brave the elements rising up in front of it, like water or fire… The extreme slow-motion enabled by the high speed Phantom Flex camera reveal the magical and fascinating spectacle of the sturdiness of the machine, faced with the elements: the flames sucked up by the rotational motion of the propellers; droplets exploding on its blades… The soundtrack, an astonishing metal rock version of Beethoven’s Ode to Joy, highlights the beauty of the images and the power of the flying machine. Freeze frame To make such precise images, Parrot used, for the [...]
Russia to test drones to monitor wildlife and track poachers
VLADIVOSTOK, Russia, Officials say they’ll test unmanned aerial vehicles at a nature reserve on Russia’s Pacific coast this summer to monitor wildlife and crack down on poachers. “UAVs are silent and can fly at a very low altitude to produce high-resolution imagery and detect poachers, their boats and vehicles,” Alexandra Filatkina, deputy director for development at the Kronotsky nature reserve on the Kamchatka Peninsula, told RIA Novosti Friday. Images from the drones will not only spot trails left by poachers’ vehicles but can also spot illegal logging sites and waste dumps, she said. Officials said the drones will greatly reduce the cost of aerial monitoring animals like brown bears, reindeer and snow sheep. Last year, the South Kamchatka Federal Reserve spent more than $32,000 on monitoring brown bears alone, officials said. The drones, which weigh about 5 pounds and have a range of 40 miles, will be equipped with inexpensive cameras capable of taking a photograph every two seconds, Filatkina said. The test at Kronosky will determine whether they can be used in other wildlife sanctuaries across Russia, she said. http://www.upi.com/Science_News/2013/05/17/Russia-to-test-drones-to-monitor-wildlife-and-track-poachers/UPI-44531368820052/ Bookmark It Hide Sites
