I am completely against the US-Israeli war on Iran. That said, they are not carpet-bombing Iran. That is, they appear to be selecting individual targets rather than engaging in carpet bombing entire areas: https://en.wikipedia.org/wiki/Carpet_bombing The choice of targets is not legally legitimate (and the entire campaign is illegal AFAICT), and sometimes they used old/invalid intel, like what happened with that girl…

They are using white phosphorus on populated areas in South Lebanon. That's as vile as one can get.

The white washing of Koresh is sickening to see. Similar to how some in the US idolize the traitor Colonel Robert E Lee.

If this was Usenet, your post would result in a “plonk” very likely.

Why did almost all Presidents up to and including Eisenhower praise Robert E Lee? Was Eisenhower a traitor also?

A certain kind of mind deals with stress by devising solutions, even if one cannot put them into action. Seeing people in Israel, Iran, the general Middle East as well as the Ukraine live in fear of drone strikes might have incentivised this person to come up with a potential way to deal with these threats. Cheap air defense would equilibrate drone warfare again: Currently drones are much cheaper that the systems tha…

MANPADS can be effective against large drones, but definitely not against the kind of FOV shit we see in Ukraine. They were originally designed to kill helicopters and low flying aircraft, and I'm guessing that's still his design intent.

>FOV

FPV.

But I really hate the whole weaponization of these FPV drones (as opposed to the bigger fixed wings ones), not just they ruined the fun hobby that a lot enjoy, but also increased the prices for the parts. Before 2022 whenever I talk about drones everyone is enthusiastic about them, what benefits they can bring like drone deliveries and all, after that, you get a hostile reaction or the government putting you on some watchlist.

This is obviously a missile, and I'm not well-versed in weapons tech, but won't this need a camera to actually track and take out a flying object? So far I just see gps and barometric sensing... Also 3D printing and some electronics, ok fine, but where do you get the rocket propellant? That seems at least as critical as the software and sensing side of things...

Yeah, this current project uses external sensors (a camera array/grid) for guidance.

He's using potassium nitrate/sugar as his rocket fuel.

Watch the video. He makes his own propellant.

The engineering is genuinely impressive for $96, but naming the repo "MANPADS-System-Launcher-and-Rocket" on GitHub is going to attract exactly the kind of attention you don't want. ITAR implications aside, the interesting part is the mid-flight trajectory recalculation on a $5 sensor. That's the same basic problem military guidance systems solve with hardware that costs thousands. The gap between consumer electronic…

Consumer GPS chips are specifically nerfed for using them in rockets; they give erroneous readings on purpose if altitude is above a certain height and/or if speeds exceed a certain speed. That’s likely why the mid-course correction software uses other methods.

This is bonkers. Video on GitHub: https://www.youtube.com/watch?v=DDO2EvXyncE I'm impressed by the kid's engineering and gumption, but I think he's a bit.. misguided, if you'll pardon the pun. The video ends with shots of Russian drone war, and, bizarrely, photos of David Koresh. I don't think this ends well.

soo... i have no kept up with what's gone on in russia/ukraine. Are those drone videos what i think they are – drones sneaking up on humans and, presumably, ceasing them of life? edit: Ok, I googled the guy > I have read the works of authors such as Jean Baudrillard, Desmod Morris, and Ted Kaczynski who believe that technology is harming us and the world. https://wiki.opensourceecology.org/wiki/User:Alisherkhojayev

Both Russia and Ukraine build millions of drones per year, most of them fpv drones that are basically remote controlled flying grenades. There's plenty of electronic warfare with radio jamming, so in some places they use drone mounted spools of fiber optic cable to control them. It's probably been the most impactful weapon type in the war for the past years.
