There are basically three levels of quad(and hexa, etc)copter devices (loosely):
1) Toy Grade: These generally cost $100 USD or less. Most have a range of 100m or less. And most will fall from the sky when they loose radio contact with the controller. If they have cameras, tend to be 720p or lower resolution. Virtually all have brushed motors. They tend to be small and light, and cause little damage if they collide with something like a window. Are used for the simple enjoyment of flying by the pilots.
2) Hobby Grade: Usually between ~$100 to $1,000 USD. Have a range of upward to 500-1000 meters, and usually have more smarts, including things like GPS positioning, telemetry, return to launch point, automatic takeoff and landing, altitude hold, etc. use FPV and/or high resolution (1080p to 2K) cameras. Majority have brushless motors. May be built up from parts and support many different motors, ESCs batteries, flight controllers, video transmitters usually in the 5.8G band, and tend to favour diversity and "cloverleaf" style antennae for control and video over simple dipole ones. If they can carry a payload, it is usually on the order of a GoPro action camera. They tend to be fast, and moderately heavy, and will certainly shatter or break a window in a collision. Tend to be used for things like amateur videography, racing, stunt flying, etc.
3) Professional Grade: From around $1000 USD and up to the tens of thousands of dollars. Range is in kilometers for both control and live video feed, and thus may require a radio operator license. Some are totally autonomous, while many have semi-autonomous such that they can follow a pre-defined flight path, or perform complex actions based upon different events. Tend to be fairly heavy and use brushless motors. Many can carry significant payloads, such as professional/broadcast quality cameras. Are used for professional videography, aerial surveying, Search & Rescue, Law Enforcement, etc.
Remember, this is a broad overview of classification for quadcopters, and of my own humble opinion. I am sure you can poke all sorts of specific holes in it, but would agree that it a good rough guide.
So with these classifications in mind, we can have a better discussion about the governance of these devices, and not confuse or conflagrate restrictions between disparate grades of devices.
Truly a Hero! I owe him a great deal!
I got my real start in Computers and Programming due to Logo. I was lucky enough to get a high school co-op placement at Ottawa's Carleton Board of Education's Computer Pilot Project, the Computer P.L.A.C.E. where I got to play with a Terrapin floor turtle, and ended up having to hack it's code fix it's programming to make it draw square "squares". I taught computer programming using LOGO, both Terrapin and Apple versions, to some of the very same high school teachers who had told me that I couldn't do programming because my math wasn't good enough. It also enabled me to get a summer job teaching at a computer day camp, and thus my career in computers was launched!
This Samhain, Seymour Papert, you will remembered among the honoured ancestors of my craft! Hail and Farewell!
Sounds like someone got jealous of Powershell and decided to a "me too!" shell for the other OSs. Meh.
I've been trying to buy them for weeks! The performance is impressive, though.
People love to hate on Windows Phone, but the Nokia/Lumia hardware is top-notch. Even their low-end phones are quite readable in bright sunlight, and the touch screens work with modestly thick gloves, too.
You mean like the Anonymous Coward who says "graphical utilities don't update the kernel"
This person should simply click the Mint update manager on their bar which brings up the graphical Update Manager Window. Then you click "View", and from that drop-down menu select "Linux Kernels". From there you can choose from all of the available kernels for Linux Mint.
I don't know about you, but that is certainly looks fairly graphical to me!
Power steering doesn't "lock solid," it becomes "much more difficult to steer." The only way steering "locks" is if the ignition turns to the point of locking the steering wheel, or something very catastrophic mechanically happens to prevent the mechanism from turning. I've had a full-size bus I was driving lose power while going down the freeway. It became MUCH harder to steer - I was leaning out of my seat, grabbing the wheel hard with both hands, and pulling HARD to keep it going where it needed to go, but it didn't "lock solid." It was simply much, MUCH more difficult to steer. My life and the lives of my passengers potentially depended on it though, so I made it happen.
Having my life or the lives of those around me depend on a crap "smart gun" firing when needed... there's no simple way to MAKE that fire if it loses power.
You can get a great deal of information from the "service tag" on your Dell equipment. Every piece of Dell equipment has one, and you can get the entire service history through the Dell website. This is very useful for service types, both inside and outside Dell. But it sounds like some people are abusing that, and I fear that will cause Dell to shut down or limit access to that service.
Umm... Eject? I've never seen an Eject key on a keyboard, certainly not on my Macbook (which is also missing "Home" and "End" keys, because Apple).
Naw, no trolling... not much anyway. When I say "close to perfect," I mean something closer to "the best desktop OS UI that's been created yet, by anyone, where most things 'just work.'" And I say that writing this from a Mac that I've been using as my primary daily laptop for two years - and I STILL hate the UI. The multi-monitor/projector support is TERRIBLE, Finder has one of the worst file explorer layouts I've seen, it's about a 10-step process to switch from normal headphones to USB or back, my task bar or whatever it's called in MacLand shrinks to where I can hardly see what I'm clicking if I open too many things at once, the network settings are disjointed, and it's not even possible to use a shortcut key to lock the desktop when I'm walking away from my desk! (And no, a "hot corner" is NOT THE SAME, even though that's the dirty cheap hack I have in place as a substitute).
So, compared to that hot steaming mess in the road, Windows 7 is pretty close to perfect.
...back in 2001, the year of Linux on the Desktop. Seriously, getting a desktop "right" is hard... Apple certainly hasn't figured it out yet, none of the Linux camps have figured it out... it's hard. The only one that may have come close to perfecting it was Microsoft with Windows 7, and then they went and screwed it all up after they had it.
"See that guy? He's crazy! Let's go for an easier target." Crazy = unpredictable = bad target. On the other hand, I've been told they probably avoid me because I look like I might rip someone's heart out with my bare hands and eat it, just to see if it tastes like bacon. So skipping is not always necessary to be a bad target.
It's an interesting article...but the video linked to it is by someone who is fairly clueless about Linux. As it's well know that Red Star OS is Linux, the video's creator should have at least taken the time to learn more about Linux so that he could comment competently on Red Star. Disappointing.
...is an enemy of freedom. How she keeps getting re-elected, I'll never understand. She ought to be tried for sedition, and hanged after being convicted by a jury of her peers.
