Great... can't wait for politicians to use this as a way to pass "common sense" legislation banning 3D printers.

[–] Janx@piefed.social 96 points 1 week ago (7 children)

Aren't they already doing that due to their hysteria over "ghost" guns?

[–] SeductiveTortoise@piefed.social 25 points 1 week ago* (last edited 1 week ago) (1 children)

I learned from Mario that ghosts can only harm you if you look away. They never had guns, but I guess the same applies for that.

I thought Luigi was the one with ghost gun

Luigi was with me and he didn’t have a gun

They can try, but the parts that make up a printer are used in tons of other applications. It isn't hard to build one from scratch.

And just like age verification it's useless because one can build a 3d printer out of an old VCR and a hot glue gun.

[–] Dettweiler42@lemmy.dbzer0.com 19 points 1 week ago

They're already trying that in New York and California, unfortunately. "Any 3D printer capable of printing parts for firearms" was the verbage, from what I recall.

[–] teyrnon@sh.itjust.works 12 points 1 week ago

They already are over 3d guns, this will send them ballistic. They want every printer to keep a record of everything they've printed. Model legislation, I think CA tried and so far failed to pass it.

Notably absent... the explosives.

But sure, if you are wondering how folks out in Yemen or Gaza managed to retaliate against their oppressors for so long, this is a textbook example of how and why. What's being proposed is collection of technology we've had since at least the 1960s that's slowly made its way into civilian circulation.

Also...

Khojayev's just-launched prototype has no effectiveness track record

I mean, we're seeing what "just-launched prototypes with no effective track record" have accomplished on the Ukraine-Russia front-lines and it's a decidedly mixed bag.

I think a harder question to answer is "Who would be interested in putting one of these into practical use?" And that gets to the real value-add of a Stinger MANPAD. Namely, the humans willing and practiced enough to use it.

Also - and again, this cannot be overstated - the model above has no explosives installed. Idk how confident I'd be around one of these things if it was actually armed.

[–] FauxLiving@lemmy.world 35 points 1 week ago* (last edited 1 week ago) (1 children)

It's not a MANPAD really.

The sensor package has no IR sensor (or radar unit) and no way to proximity fuse.

It has GPS, accelerometer and barometric pressure. It's more like a rocket powered artillery shell than an anti-air weapon.

Or, given the lack of payload, it's more like a high speed burrito delivery device.

I synthesize energetics. I can make a primary explosive that is stable enough for cap usage with a solo cup. I can synthesize secondaries like RDX above (one of the more complicated common ones) in short order with a basic chemistry set and the internet to order basic reagents. None are controlled substances.

It is trivially easy to make effective shapes charges and energetics at home.

Synthesis is federally legal in the US so long as you do not assemble into a device or transport. You can do both with an SOT as an FFL.

If I wanted to, I could make a shaped charge that was point imitated and base detonated for the above projectile and it would punch through about 1.5 feet of homogeneously rolled steel.

The limit to threat is not the access to explosives, as the chemistry and processes are published freely online as easy to replicate. The drone parts and control surface actuation is by far harder and I say this as someone who has a professional background in computer science and software engineering.

Imagine spending thousands of dollars stockpiling assault rifles and ammo for your revolution only to have your entire milita wiped out when some nerd with a $100 homemade missile blows-up the UHaul you all piled in the back of.

Clearly it’s just a big-ass gun that shoots 5000 caliber rounds. So it’s protected by the 2nd Amendment.

There's an anecdote that comes up in software about people working on missile software not caring about memory leaks because it's going to explode anyway before that becomes an issue.

Who cares about bugs in your software if it's a hobby project that's going to blow up anyway.

Also, including Claude doesn't inherently mean vibe coded, it can be for writing tests, small components, or debugging.

If I'm understanding this correctly, this is more valuable to underfunded military forces but not for the 3d printed ghost gun types. This doesn't include propellent or explosives, which are the controlled parts. That's awesome though.

That's fucking nuts.

I have a lot of thoughts, but all I can really say is that's fucking nuts.

[–] frongt@lemmy.zip 17 points 1 week ago (6 children)

Neat. I wonder if there is anything you can use as a warhead without it becoming a destructive device. Chalk rounds?

I'm also curious to know the rocket velocity compared to actual MANPADS. I'll have to watch the videos later because I'm also curious about whether they're independent or require the launching laptop to stay connected.

[–] Samskara@sh.itjust.works 18 points 1 week ago

Velocity and range are also my main questions, as well as tracking quality and speed. The video doesn’t demonstrate it hitting a flying target.

Common MANPADS like Stinger, Strela, etc. use infrared tracking. The seekers are high performance and fast but need complex supercooling with gas. Using a MANPADS you only have seconds, to arm, aim and track, then fire the missile against a fast moving target before it‘s out of range. These can hit low flying supersonic jets.

Still this project is very impressive and hints at the possibility to build cheap low end MANPADS that can target slow moving strike and observation drones, maybe helicopters.

It’s another indicator, that mass produced cheap precision weapons are a major trend in warfare.

This is the same kind of thing the local Airsofters were building with an arduino and a few hats a decade ago. It's not a functional "weapon" it's just a hobby rocket with fins (that admittedly looks real fun to shoot)

"Do you have natural freckles or did you use that shoulder-mounted guided missile prototype again?"

[–] testfactor@lemmy.world 12 points 1 week ago (7 children)

I wish the video actually had him using it to hit a drone or something. As is, it only shows one actual launch, and it didn't look all that impressive. His motors didn't seem to have enough umph to let the missile stabilize properly.
