apm2.5 pinout
Hi all,I am writing my own code for the ardupilot 2.5 board and have the eagle files and schematics, however I am totally confused as to the pinout. (my vehicle is a bit different from a standard vehicle and connected with my work so I am not allowed to use the open source code or library). If the project works I will publish details.I am working on the 8 outputs, using 1-4 as servo outputs and 5-8 as digital outputs.The schematics would give the following:o/p8 - pin 5o/p7 - pin 6o/p6 - pin…See More

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)

Google acquires kite-power generator
Well I did’nt see this coming. Using lots of UA tech Google invests in yet more cutting edge stuff (ed) Google has acquired a US company that generates power using turbines mounted on tethered kites or wings. Makani Power will become part of Google X – the secretive research and development arm of the search giant. The deal comes as Makani carries out the first fully autonomous flights of robot kites bearing its power-generating propellers. Google has not said how much it paid to acquire Makani, but it has invested $15m (£9.9m) in the company before now. In a statement posted to its website, Makani said the deal would “provide Makani with the resources to accelerate our work to make wind energy cost competitive with fossil fuels”. Rather than use fixed turbines to generate power, Makani has been experimenting with “flying wings” adorned with several smaller turbines that act as propellers as the craft takes off. Makani claims that mounting the turbines on a wing is more efficient as large numbers can be built with fewer materials than traditional tower-based turbines. In addition, the robot wings can land to avoid damage if wind speeds are too high or during bad [...]
Unmanned aircraft can protect crops from locusts
by Gabino Martinez Serrano The world population is growing at a rapid pace. Today we are almost seven billion people and it is estimated that the figure will exceed 10 billion in 15 years. The world’s need for food will double, but the world’s arable land remains the same. Experts say that to increase performance, it is important to plant each crop where it can best develop, increase the yield potential of plant varieties and to reduce adversity posed by pests which have become a real problem. Failure to protect crops from pests would reduce harvests to just over half. Locusts are unique because they undergo a phase change. This means that under certain circumstances related to climate and population density, their behaviour changes and they move, eat and behave as a group, forming gigantic clouds and can travel great distances devouring crops in their path. These pests can affect 20 per cent of the surface of the earth, spreading through Africa, the Near East, and Southwest Asia. More than 65 countries may be at risk of swarms, invasion and reproduction. The last powerful plague occurred in 1988-89, threatening as many as 43 countries, one fifth of the world as [...]
ESCC to use donated unmanned aerial vehicles for science
Ted Shockley MELFA — Launching unmanned aerial vehicles from the Eastern Shore could be a financial plus for the area, and Eastern Shore Community College is positioning itself for an associated educational and training partnership. A link between the two was seen recently when an Aerosonde aerial vehicle donated to the college was unveiled in front of a gathering of staff members and industry experts. “We have something tangible, real, that the students can see,” said College President Linda Thomas-Glover of the unmanned airplane, which from wing to wing was bigger than a typical dining-room table. The particular model was used for years out of Wallops to gather weather data and has flown into hurricanes, said Jon Borcik, a program manager for AAI Corp., which oversees the Aerosonde program. He called it a “coming home mission” for the plane, a fitting place for an aircraft based at Wallops to continue its service. The plane will be used to stimulate an interest in science and also be studied by various college classes. The donation was arraigned by Peter Bale, board chairman for the Association for Unmanned Vehicle Systems International and a former program manager for Aerosonde North America at Wallops. At a [...]
Small Tactical Unmanned Aircraft Systems Achieves Milestone C Approval
Insitu announced today that RQ-21A reached Milestone C under the Small Tactical Unmanned Aircraft System (STUAS) contract with Naval Air Systems Command (NAVAIR). The achievement will enable the program to transition from the Engineering, Manufacturing and Development (EMD) phase to a Low Rate Initial Production (LRIP) phase and enter initial operational test and evaluation (IOT&E). “This milestone represents the dedication and commitment of the entire government and industry team to executing a challenging and fast-paced EMD program,” said Ryan Hartman , Insitu’s senior vice president of Integrator Programs. “I couldn’t be more proud of the Insitu team. Our greatest asset is our engineering talent and this event represents yet another significant engineering achievement for them.” “This milestone and the LRIP decision is a great accomplishment for our NAVAIR and Insitu team. The rapid development, systems engineering and testing has been superb. The sense of urgency and driving force behind our NAVAIR and Insitu team has been, and continues to be, the simple fact that the RQ-21A UAS will be the first organic & dedicated multi-intelligence UAS for U.S. Marine Corps and Navy tactical commanders. The real-time, actionable intelligence and maritime domain awareness coming from multiple sensors off an expeditionary and ship-capable Group [...]
NM drone testing center could soon face competition
Dan Mayfield New Mexico could lose its lead on unmanned aerial vehicle development when the Federal Aviation Administration lays out a new set of rules that allow more airfields to test UAVs, a state leader in the industry said. The Unmanned Aircraft Systems Flight Test Center, an airfield run by New Mexico State University and the FAA, is the only FAA-approved UAS, or drone, flight test center in the nation. The center logs data from about two flights daily of commercial drones, which weigh anywhere from 15 ounces to 600 pounds. But last year the FAA said it will authorize six more sites for drone testing. “As soon as the FAA opens the door, there will be an explosion,” said Dennis “Zak” Zaklan, the director of the UAS FTC. “At this point, nobody knows. It depends on the FAA. It creates competition.” http://www.bizjournals.com/albuquerque/news/2013/05/22/drone-test-center-could-face-competition.html Bookmark It Hide Sites
