    3D printers are even less useful here though. The rocket bit can be replaced with a cardboard tube and some balsa fins. The important parts are the active control and circuitry.

  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.

  source

  • FauxLiving@lemmy.world ⁨3⁩ ⁨weeks⁩ ago

    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 explosive, it’s 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.

      You’ve got enough information to try to execute the above formula. Okay. And you’ve still got all your fingers after attempting this… more than zero times?

      Absolutely. We invented gunpowder centuries before we invented airplanes.

      That said… as an anecdote, I had a friend who had a janitorial position. Used a bunch of bleach to clean a particularly stubborn toilet and dumped a bunch of bleach into the bowl. His coworker came in behind him and proceeded to piss in said boil, creating a toxic miasma that forced them to exit the restroom quickly and heavily ventilate it before returning.

      “I could cook up some blasting caps with the trash from a frat party” is a theoretically believable claim.

      “Every time I clean up a frat party, I add a dozen shaped charges to my inventory” is not.

    You don’t need explosives. It has a spot in the front for a camera. One of the new microcontrollers with AI accelerators can do face recognition extremely quickly. It would be possible to use it as an assassination tool.

      As the bps space YouTube channel has shown, reliability is paramount in any launch, especially a guided launch.

      That and people duck when shit flies at them, unless it’s supersonic, which again, as bps space has shown, control of a supersonic flight is extremely difficult to get right.

    Would it be possible to make a curved laser for laser artillery?

    source

    • UnderpantsWeevil@lemmy.world ⁨2⁩ ⁨weeks⁩ ago

      Certainly possible. But you’re still stuck on the r^2^ problem of diminishing returns at a distance. Light doesn’t like staying in a tight beam. The vortex loop is typically not much bigger than the wavelength. I don’t see much of a solution for transmitting energy long distances through air.

      Atomize* some propelant, boom, explosive.

      The trick is to get the atomized propelant to “boom, explosive” at the target and not in your backpack.

      Also, you probably want a “boom” sufficient to accomplish whatever demolition you’re planning, which - again - raises the stakes regarding what’s in your backpack.

      There’s a classic little film called “The Wages of Fear” that explores the hazards of amateurs transporting high explosives over long distances.

      Does that literally mean “make dust”? I think “powderize” might be a better translation in this context, if it’s a solid, or “aerosolize” if it’s a liquid. I’ve never been a big fan of the word “atomize” in any case.

      Atomize, from the original Ancient Greek adjective atomos, meaning “uncuttable” or “indivisible”.

      Seems pretty apt to me. You have rendered it into its smallest constituent pieces through physical means, any further reduction requires chemical processes, or high energy physics. Coincidentally, a simple spark provides both.

  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.

  source

  • Samskara@sh.itjust.works ⁨3⁩ ⁨weeks⁩ 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.
