Saw some guys racing drones like the first video in a local park. Every bit as fast and maneuverable, but they had them going through 6 ft gates on a course roughly the size of a football field. I assume they're not really human-controlled because I could barely track where the drone was, let alone give it precise controls for how to pass through the gate. Went home and told my wife "If we ever get into a war, humanity is fucked."

I fly FPV drones.

The idea they are not human controlled is absurd.

They handle like nothing else. There is literally nothing else to compare them to so they seem almost alien. You could dive bomb a gate yourself after maybe 10 hours of practice in a simulator.

Of course the first time you try you won't even be able to keep the drone in the air but really quickly the controls become second nature.

The irony is the guys at the park were most likely not even great pilots. Look up Mr Steele on youtube if you want to watch someone do really inhuman stuff.

I fly FPV drones too and the batteries suck and this thing seemed to have 40+ minutes of flight time.

Even top of the DJI drones (which are not exactly freestyle/racy) would top out at around 30 minutes.

Not implying aliens, but I wish we had that kind of battery technology in my Nazgul5, if it's a drone they've seen.

Hydrocarbons have 100 times the energy density. We have the technology.

Fuel cells for drones are a thing with about 3x endurance https://www.intelligent-energy.com/our-products/uavs/

Turns out humans are actually really great at controlling ridiculously fast aircraft, the drone races are controlled by a person looking through a camera pointed forward on the drone. You can think of it like speedrunning an N64 game, finding the timing that lets you act instead of react.

But +1 humanity’s fucked, don’t Google Slaughterbots but maybe Google how to build an EMP, it’s easier than you think.

Conversely, shielding electronics against EMPs is surprisingly easy. Just wrapping things in aluminium foil goes a long way.

Doesn't this also mean that they would not be able to receive comms?
Re:Police helicopter's 100mph chase with 'super sophisticate... by ben_w on Sunday August 22, 2021 @05:38AM (#28264116)
Comms can also be laser, and the drones can be pre-programmed and self guiding. Though in either case, you can still always dazzle either the sensors or the comms (MEMS sensors used for inertial guidance are vulnerable to ultrasound IIRC). And I’m sure the military either have or are developing an anti-drone-drone.
Re:Police helicopter's 100mph chase with 'super sophisticate... by lambdasquirrel on Sunday August 22, 2021 @07:47AM (#28264682)
Well the military has AESA radars that can be programmed to act as a microwave laser so there’s that. A Faraday cage won’t be of much help if it’s literally cooked.
Re:Police helicopter's 100mph chase with 'super sophisticate... by dismalpedigree on Sunday August 22, 2021 @08:36AM (#28264963)
Um. What do you think the grid of wires in the window of your microwave is for? Its a faraday cage to keep you from being cooked.

If you pump enough power at the shielding, a) some of it will get through and b) the shielding itself will get very hot from induced eddy currents.
Re:Police helicopter's 100mph chase with 'super sophisticate... by relaxing on Sunday August 22, 2021 @04:11PM (#28269133)
> pump enough power

Problem is you’re fighting path loss which is exponential with distance, whereas the power of your emitter is scaling linearly.

No, EM radiation power decays quadratic with the distance, not exponentially.

You’re right of course.
Re:Police helicopter's 100mph chase with 'super sophisticate... by epr on Sunday August 22, 2021 @07:39AM (#28264647)
Not necessarily. You can transmit signals between completely isolated circuits with an optocoupler for example.
Re:Police helicopter's 100mph chase with 'super sophisticate... by faeyanpiraat on Sunday August 22, 2021 @04:23AM (#28263782)
If you folded the entire thing then it could mean that.

But you want to shield the parts which do not directly need to receive rf signals, like the mainboard.

Sounds like a good way to get on a list.

No worries, a lot of people search about EMP every day. Smaller EMP devices were (are?) commonly used to rob poker/slot/vending machines. I have no idea of the truth behind this, but there are homemade devices being sold online, sometimes disguised as "research" devices with photos showing how they can turn on a CCFL lamp from distance, while others blatantly declare their purpose.

Well, once you get past the loaded allow part, if you read their mission statement, you will note it is their actual mission:

"Our company mission is to organize the world's information and make it universally accessible and useful."

Never thought of it that way, part of the world’s information is, “who’s asking?”

Re:Police helicopter's 100mph chase with 'super sophisticate... by NegativeLatency on Sunday August 22, 2021 @01:36AM (#28263170)
Usually they’re human controlled with an FPV camera setup. Lots of stuff on YouTube to check out related to it if you’re curious. The camera and live video feed to goggles greatly increases what you can do with the drone
Re:Police helicopter's 100mph chase with 'super sophisticate... by jahnu on Sunday August 22, 2021 @03:30AM (#28263608)
And they use analogue video signals to avoid encoding/decoding latency
Re:Police helicopter's 100mph chase with 'super sophisticate... by snovv_crash on Sunday August 22, 2021 @03:53AM (#28263677)
Not always, there are starting to be some good digital systems. Analogue is just cheaper and lighter.
Re:Police helicopter's 100mph chase with 'super sophisticate... by 05 on Sunday August 22, 2021 @04:17AM (#28263757)
“Starting to”? DJI FPV is two years old and naked Vista is negligibly heavier than analog (and it mostly matters for micros, anyway)
Re:Police helicopter's 100mph chase with 'super sophisticate... by dylan604 on Sunday August 22, 2021 @10:21AM (#28265687)
Yes, something only available for two years qualifies as starting to. In the realm of transmitting video 2 years is definitely early stages.
Re:Police helicopter's 100mph chase with 'super sophisticate... by snovv_crash on Sunday August 22, 2021 @05:55AM (#28264174)
Naked vista overheats, there's a reason it comes with heatsinks.

There's also been severe availability issues with the DJI gear.

Re:Police helicopter's 100mph chase with 'super sophisticate... by jahnu on Sunday August 22, 2021 @02:10PM (#28267932)
Oh wow cool! And what sort of latency can they achieve?
