Darrell Burkey replied to Damien Fitzgerald's discussion arducopter low battery audible alarm in the group ArduCopter User Group"Good news. For once there's a part that's only a couple of dollars that does just what you want. They are called Low Battery Alarms and are quite loud. I've linked to HobbyKing but you can get them on eBay as well."
Damien Fitzgerald replied to Damien Fitzgerald's discussion arducopter low battery audible alarm in the group ArduCopter User Group"Yes but all I should really need is a light or piezoelectric speaker that plugs directly into the apm and the code to fire the speaker or led when below a voltage. That would be awesome if it exists ?"

There are two things you can do:
reduce NAVL1_PERIOD a bit. Try reducing by 5 at a time until you are happier with it.
use a larger WP_RADIUS value

It sounds like the APM doesn't have correct radio calibration. Did you re-run radio calibration after switching to ELEVON_OUTPUT? In particular I suspect your RC1_MIN and RC1_MAX values are larger than the values you get when you…"

arducopter low battery audible alarm
Is it possible to add a speaker to the quad that noises when the battery goes low. I have the 3dr battery voltage monitor but having to hook up the laptop is a pain
Daniel Estes added a discussion to the group ArduCopter User GroupArdupilot Mega 2.5+ Looses Power at Failsafe Alarm
I sent another post of the same message, but I messed up sending it to one individual. Sorry for the mistake.My question is during the last two times I waited until the failsafe alarm went off to land my hexacopter. Although, when the alarm went off, I lost power at my radio. I was near landing and I believe it was preparing to RTL at 9.6 volt (low battery) due to my settings. The copter was low enough to touch the ground, but the sudden acceleration tipped the copter so one of my blades…See More

Jack Crossfire commented on Roberto Navoni's blog post VR GIMBAL ( Board Control and IMU ): We are ready for developer."After thinking about the problem, the Z axis IMU is what you want. The relative roll/pitch of the 2 IMU's determines how much yaw is contributing to roll/pitch. It would take fusing the 2 IMU's to determine all the feedback of the motors."
Jim Frantz replied to Hugues's discussion What are these clicking sounds of the motors ? in the group ArduCopter User Group"Your clicking noise is possibly BLDC motors loosing sync. You could correct this by trying a different ESC or programming the existing ESC and selecting a different PWM frequency often found in the ESC programming options list.

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)

UAV news from sUAS News
Germany Scuttles UAV Program, According To Reports
Agence France Press is reporting that Germany has cancelled a planned ‘Euro Hawk’ UAV programme because it believes European authorities will not certify them to fly in civilian airspace. More from AFP: Germany had “no hope” of seeing the unmanned aircraft, part of a programme that would have cost more than one billion euros ($1.3 billion), approved for use, said the source speaking on condition of anonymity. The European Aviation Safety Agency has said it would only certify the drones to fly over unpopulated areas because of a lack of an anti-collision system to protect airliners, according to German press reports. “The equipment is not ready for approval without immense expenditure,” the source added.

Israel is world’s largest exporter of drones, study finds
By Gili Cohen Israel is the world’s largest exporter of unmanned aircraft, in terms of the number of systems sold, a study has found. Over the last eight years Israel has exported $4.6 billion worth of unmanned aerial vehicles, according to a study by the business consulting firm Frost & Sullivan. UAVs, or drones, constitute nearly 10 percent of Israel’s total military exports. Unmanned equipment exports are a relatively volatile market, the report shows. Israel had $150 million in UAV exports in 2008, a figure which increased substantially in 2009 to $650 million. Exports of the small surveillance planes peaked in 2010, a record year for drone sales, to $979 million. http://www.haaretz.com/news/diplomacy-defense/israel-is-world-s-largest-exporter-of-drones-study-finds.premium-1.524771 Bookmark It Hide Sites

Texas Senate approves bill to curtail drone photography
Remember the River of Blood story, it went viral. Seems the Texa’s senate would prefer to sweep what Texan businesses get up to under the carpet. If this act makes it all the way through and you let this sort of images out into the wild you will be facing the law. It should not have taken the images to uncover the massive pollution that was occurring. Texas should know the condition of its rivers. I would be ashamed to live in a place that seems to care so little for its environment. Good news though for other states bidding to host one of the FAA Test sites, Texas Privacy Act (HB 912) could be a royal PIA for people testing. Use of drones to capture photographs and video images on private property without permission of the owner would be prohibited under a bill the Senate passed Friday. Supporters of the ban say it is needed because of the increasing incidence of indiscriminate surveillance by unmanned drones. The Senate amended the bill, already passed by the House, to exempt unmanned vehicles used by police and law enforcement officers and to protect citizens who use a cellphone or other recording device to film [...]
Congress gets mixed advice on drone laws
AP WASHINGTON – The growing use of unmanned surveillance “eyes in the sky” aircraft raises a thicket of privacy concerns, but Congress is getting mixed advice on what, if anything, to do about it. A future with domestic drones may be inevitable. While civilian drone use is currently limited to government agencies and some public universities, a law passed by Congress last year requires the Federal Aviation Administration to allow widespread drone flights in the United States by 2015. According to FAA estimates, as many as 7,500 civilian drones could be in use within five years. “Technology is great — as long as it’s used the right and proper way,” Rep. Jason Chaffetz, R-Utah, said at a House Judiciary subcommittee hearing Friday on issues surrounding drones — which can be as small as a bird and as large as a plane. http://www.pressherald.com/news/nationworld/congress-gets-mixed-advice-on-drone-laws_2013-05-18.html Bookmark It Hide Sites
