why is there a yiff thread, and why is it discussing quadcopters of all things?

It’s a joke about the pronunciation of the acronym for the Graphics Interchange Format. It’s discussing quadrocopters because they have been depicted in a motion picture.

My dad was with OSHA back in the 90s and did fatality investigations for another part of .gov before that. I forget the where, who and when, but one of his funnier fatality stories is about this guy who was doing work on the rim of an earth-mover tire. They're really big and you're required to put a cage around the tire if you do any maintenance on them because PSI etc. One of the police on scene was vomiting when my dad arrived. And he didn't see a body so he asked a different, not vomiting cop where the body was. Cop pointed up, and uh, apparently this fella was sitting right on top of an earth-mover tire, busted the rim while working on it, launched straight up and accordioned into the warehouse ceiling, Wile-E-Coyote style, with his legs coming down and the rest of him being kind of a paste.

at that scale why not just build a small helicopter? other than 'government regulations are strangling my innovative spirit, maaaaan!' of course.

Multicopters are only easy to control because a computer is hooked up to a bunch of accelerometers and gyroscopes and damps instability before it gets too far. Helicopters have more benign flight characteristics (I never thought I would say that) that require nothing more than human skill to reign in. A helicopter could get a computer to make it less demanding of the reflexes but that doesn’t really make it safer. It just makes it easier to get in over one’s head. Then we get more headlines like “Neighbors say it's no surprise Lincoln County man crashed helicopter”. Flying a multicopter with an amateur‐built control system is the worst of both worlds.

So the take away from all that is that hopefully a lot more people try this so there is more content for here and the schadenfreude thread.

Multirotors are also pretty inefficient compared to traditional aircraft because of how the thing is being brute-forced into the air, and stability is being achieved by the flight controller's constant adjustment of propeller velocities. https://oscarliang.com/quadcopter-helicopter-compare-cons-pro/ Apparently that monstrosity cost $10k to build, and is basically a metaphor for shoveling money at a problem to make up for lack of skill. He could have built (or hell, bought) an ultralight plane for half the cost, and have more than ten minutes of flight time. poo poo, a paramotor and parachute would be safer than that thing and an order of magnitude more fun.

Was at another site today where yearly Test and Tagging of electrical appliances/tools is done internally. I overheard "we do it in Feb so we can put a 1 in front of the 2 to get an extra 10 months, then coast the Xmas period into year two for another legit test" It takes loving 5 minutes if that per appliance. And risking the company over essentially the same amount of work (going to every device and writing a 1).

The competitive advantage of multicopters is the power to weight to price ratios at the smaller scales. You can have a 600g aircraft that while it can only fly 3mn, will do so with a sustained 10:1 power to weight ratio, with 4 moving parts. Or a DJI thing that's twice the weight and flies a camera around for half an hour and costs a couple hundos to build at scale. There's no point at all to sizing them up because they lose everywhere to better and more appropriate craft types, and the prices go ballistic.

I overheard "we do it in Feb so we can put a 1 in front of the 2 to get an extra 10 months, then coast the Xmas period into year two for another legit test" We're setting up a new on-site mineralogy lab in a building that used to be used for assaying before the mine got too big to be able to keep up with that stuff in-house. The airconditioning units were last tagged in 2007, so they all got tagged out. The guys working in there turned them on because it was hot - to be fair, it was 42°C. The foreman who tagged them out came in, turned them all off and snipped the ends off their power cables, then reamed out the dudes who turned them on for not just stopping work. "We have extreme weather condition rules you dinguses, if it gets that loving hot, you just stop working, you don't risk an electrical fire or worse".

Which is weird, because they'll trip internally anyway. The switch is not on a hard-connection to the contacts. This just means you can't reset it when it does.
