There are 2 short segments in the video showing the actual performance and thus far it is a complete [1] failure [2].
The guy has a talent, and he put together a nice prototype based on OpenRocket [3], but with all due respect, this is not a rocket, and you are not going to win any war with this toy, even if all your enemy has are rocks thrown at you from pretty much similar distance.
The remix of computer games / Ukraine / Martin Luther King / Vietnam / David Koresh just adding more to the amateur spirit and confusion.
You don't need to win any wars with it if you can use them to sow confusion, obscure the firing of more serious rockets, and/or trigger a sufficiently more expensive response.
It clearly needs more work, but if an amateur can get this far at this low cost, odds are you'll see attempts at overwhelming attackers or defense systems by sheer volume with cheap decoys like this long before they become an actual threat in and of themselves.
Get the a bit more stable, and force an attack to try to take out dozens of these because one of them might be a real threat, and you'll have created a problem.
I'm surprised nobody else has pointed this out. The entire YouTube video has only two short clips of the actual rocket being fired, and in both cases the clips are very short and only show the rocket being fired and then following an erratic flight path, and then get cut before showing the rocket hitting anything.
For all the technical info given in the video, there is a curious lack of any data regarding the actual accuracy of the system. What percentage of rockets tested managed to hit anything and at what range?
Yes, I don't think this project is a serious threat as a weapon, it's more interesting if viewed as a politically provocative stunt, to get people thinking about the relationship between technology and war.
Check out Joe Barnard's youtube channel BPS.Space where he's documenting his development of "high power" (hobby) rockets. Those are relatively small rockets still but nonetheless he's getting into performance regimes where the engineering starts to be tricky and the details really matter. The more extreme your rocket gets, the difficulty really ramps up quick.
Fireworks rocket do not cost as much. But if you want high precision and high speed, that simply is expensive. Also the area is of course restricted making it more expensive as most states do not want DIY rockets everywhere.
Even if the correct sensor could be chosen (whatever it is), unlikely is attainable by consumers and the technology would definitely be export controlled in the US.
I think MEMS gyroscopes and accelerometers used in consumer drones should be just about good enough to measure orientation and acceleration, and those are cheap and easy to get.
You could integrate acceleration to get speed - the flight is short enough to make compounding errors easy to ignore.
I think thanks to drones and RC hobbyists, there's a generally nice body of knowledge on how to get good enough data from consumer hardware to keep things flying.
And that’s ok if it’s failing to do the job as intended, learning is acquired, and it looks fun to build, I am in the field and I find it great homemade concept.
Realistically, I doubt there’s ANY system out there will be able to counter small weaponized drones that are flown manually let alone with AI, you might have some workarounds, but never a real counter.
From what I can tell, Ukrainians are having some success with converting guns into automatic turrets that can track and shoot down drones via sensors, and the rifle-equivalent of birdshot.
> Realistically, I doubt there’s ANY system out there will be able to counter small weaponized drones that are flown manually let alone with AI, you might have some workarounds, but never a real counter.
Weaponized drones (say D_A) can be countered by other weaponized drones (say D_B), equally cheap or cheaper than D_A because the D_A is usually targeting something larger (so more payload) and typically has a longer range. D_B only needs to wreck D_A at a shorter defensive range. That's what Ukraine is doing.
You can also use drone swarms with coordinated action so that each drone in the swarm is only targeting one other drone, and automatic re-targeting if one node misses. [1]
> I doubt it, as D_A's target is stationary (and could be reduced to GPS coords) while D_B's target is moving.
It's a good point, though I should point out that GPS denial is assumed in those sort of contexts as a first countermeasure so D_A likely has alternative targeting, and that smaller drones can move faster with less energy storage, which itself requires less weight, compounding the benefits of being smaller.
"Realistically, I doubt there’s ANY system out there will be able to counter small weaponized drones that are flown manually "
Why would lasers not work?
Those cheap drones are made from plastic, if you have a laser powerful enough and a target guidance system (like a camera and a PI) - then you would just need enough of them.
- are cheap to shoot
- do not fall on someones head if they miss (unlike firing bullets and rockets at a drone that will come down again)
- do hit the target immediately if aimed right
Problems with lasers are, cooling, power consumption limiting mobile use - and indeed targeting and fog and clouds.
At long distances the small cross section of the drone requires tight focusing (expensive optics) or a high power, preferably pulsed laser (expensive laser) or both.
Not impossible but many times more expensive than the drone
Lasers won’t effectively work, it’s a two part equation, detection and targeting. To neutralize a target using a ground-based laser, you need an enormous power, and still it won’t penetrate a high distance/altitude in the sky, environment factors also to be considered. The detection part is even harder, these small 8in drones are almost impossible to detect unless you can hear it, aka it’s over, because they can fly at 250km/h, too small to be visually detected, acoustic sensors will fail to detect them, and radar will miss it as a false negative since it’s the size of a bird. I have seen some systems trying to combine all that to detect them plus AI for flying pattern detection, but they are far from being reliable in practical applications.
Unless you mean it just can't detect objects that small, my guess is we'll see things calibrate toward a lot more birds being cooked in active war zones vs drones with explosives being let through.
"let alone with AI" what's falling into the AI category here perhaps is the key question, since microseconds counts, and LLM are very slow!
Even the fastest "real-time" LLM frameworks currently report sub-second latencies around 120ms. This is fine for high-level mission planning (e.g., "fly to the red house") but too slow to prevent a drone from hitting a tree at 50mph (80 KM/h)[1]
Whilst the Shahed-136 kamikaze drone typically flies at a maximum speed of around 185 km/h (roughly 115 mph or 100 knots).
> "let alone with AI" what's falling into the AI category here perhaps is the key question, since microseconds counts, and LLM are very slow!
LLMs (Large Language Models) are far from the only type of AI around. It's a pretty broad field, and there are real-time AI systems, for example, self-driving cars, which have the response times you're thinking of. [1]
"Jet airplanes for sure are completely safe from small drones."
That feels like a bold and unsupported assertion. Ask a pilot how they'd feel about takeoffs or landings through airspace filled with adversarial drones.

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 electronics and mil-spec capability keeps shrinking and this is a pretty stark demonstration of where that trend leads. A few years ago this would have required an IMU that cost more than this entire build. The democratization angle cuts both ways though - the same accessibility that makes this cool for hobbyists makes it genuinely concerning from a proliferation standpoint.
> The gap between consumer electronics and mil-spec capability keeps shrinking
My friend's brother works in munitions and had, in his spare time, designed and prototyped a missile that could be built for about 10k. He pretty much was ignored by the contractor he works for.
Shockingly, as of a couple weeks ago, they are all hot and bothered to talk.
Cheap sensors look impressive in demos but drift and calibration wreck repeatability unless you babysit launches so nobody in defense is sweating this yet.
For a sub-minute flight the drift budget is actually pretty forgiving — a MEMS gyro drifts maybe 1-3 deg/sec, and if you're fusing with accelerometer data you really just need "which way is up" and "am I still pointed at the target." A $5 IMU can hold that for tens of seconds.
Where you're right is repeatability. Mil-spec works the same on launch 1 and launch 500 across temperature extremes. Consumer MEMS you'd need to characterize each unit individually — fine for a demo, impractical at any scale.
You can calibrate any sensor, its just a manufacturing step, and while cheap ones may be inaccurate and drift over time, I'm pretty sure the good enough ones (which cost tens of dollars, not fractions of a dollar) are accurate enough to work for the seconds-to-minutes flight time of a rocket like this.
They should be sweating, because if the other side can fire 100 rockets for $10k that are close enough to not immediately and obviously be off target, and you don't know whether a more expensive one with actual explosives is hiding within that barrage, you now have 100 targets to try to intercept, and suddenly your costs have gone up dramatically while the other sides costs has barely moved.
100 rockets for $10k is not happening. The price floor is not dictated by the electronics (which did get cheaper), it's dictated by the rest of the system: propulsion, warheads, arming and safety, QA, traceability, climate and shelf life stability.
Take a look at Raytheon's manufacturing line: https://www.youtube.com/watch?v=kCCkVAHSzrc That's what it takes to have missiles that are nearly guaranteed to perform to specification every time. You can stockpile the packaged missiles in a non-climate-controlled shed for years, replenish them at sea while being showered with salt water, subject them to shock of a nearby blast while in a VLS, and they will still launch, go up to Mach 13, and catch an incoming ballistic missile nearly every time.
Sure, Iran's ballistic missiles are simpler than SM-3, but they are still subject to most of the constraints. They still need perfectly cast large size solid rocket motors that don't crack after being stored for a year, they need warheads that only go off when they are supposed to, they still need to trace every part for QA, etc. There's a vast gap, largely invisible to amateurs, between garage prototypes and stockpiled AURs.
> propulsion, warheads, arming and safety, QA, traceability, climate and shelf life stability.
You're entirely missing the point.
These do not need to be reliable for the scenario I hinted at. They need to be large enough that if one of them is a higher quality rocket (not part of the $10k) that contains actual explosives, you have serious destruction on your hand. Maybe something that looks large enough for that will drive the cost up and we're talking $20k or even $100k instead of $10k.
The precise cost is largely irrelevant, as long as the total cost is a tiny fraction of the cost of a missile interception.
The point is you'd be multiplying the cost assymmetry by forcing a massively outsized response. Because if you don't try to intercept them, every future barrage will include a real rocket. If you do try to intercept them all, you'll be burning through massively expensive interceptors to take out a bunch of cheap toys.
If I was ever considering an insurgency, or a war, I'd be stocking up on vast quantities of toys.
Visual SLAM on a rocket would be wild. The frame rates you'd need at those velocities are brutal though — feature tracking falls apart fast when your entire visual field is changing at hundreds of m/s. Drones are the sweet spot where camera-based nav really shines.
It's not really terribly new actually, in the past, rapid advances in consumer technology have enabled other sort of weapon guidance systems. For instance, the development of extremely compact television cameras available to consumers directly lead to the development of the Walleye television bomb. It happened when one nerdy guy was fucking around with his new camera and realized that he could automatically track track features in an analogue television signal using some quite basic analogue electronics. Point the camera into the general direction of the target and you can then "lock on" to some target feature and based on contrast it could tell how that feature was moving around in the image.
He implemented a 1D tracker in his garage, took it to work and showed people. A few years later these bombs are taking out bridges and even sometimes hitting moving trucks.
People made self-guided missiles with 1940s technology, in the 1940s. It can't be too much of a surprise if someone right now can make guided missiles in their garage with 2026 electronics. At this point the "guided" feature is trivial, the "missile" part is doable, and the weapon has probably become the tricky part.
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.
The restrictions on GPS prevent ballistic missiles, not MANPADs. Typical limits are 515 m/s and 18,000 meters (try using your phone's GPS on a commercial flight, it works fine near a window). Update rate is probably the biggest issue with GPS and MANPADs.
What you are likely thinking of is the "selective availability" system, which intentionally provided slightly inaccurate data to civilian clients, while military receivers could decrypt the most accurate info. But this has not been used for many years now.
Other than that, GPS is a one-way system, it does not know you exist, how fast your receiver is moving or "give" different information to one client vs another.
Even if it did, this is essentially a toy and moving slower and lower than a general aviation plane.
It uses accelerometers and other sensors because they can be sampled and integrated hundreds of times a second. The $5 gps module is 9600 baud serial and provides one update/second (or maybe 5/sec depending on which part number you pick).
It would be interesting to see if those are only for external sale vs restricted for sale within China.
If China allows those unrestricted chips to be sold internationally but not domestically it would be a strategic long-term decision, I would think. Destabilize the neighbors but not themselves.
The more likely reason is that their government has simply not gotten around to restricting it.
Owning a system designed for surface to air weapon carries life imprisonment any USA, without any intent for violence, just simple possession or conspiracy to possess[]. Doesn't even matter if you have an NFA stamp, there is no exception except if it's done with authorization and behalf of the government.
Merely having a device intended to guide the rocket is also the same penalty.
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.
> The video ends with shots of Russian drone war, and, bizarrely, photos of David Koresh.
You're omitting that the end of the video also features pictures of Martin Luther King, Vietnamese civilians during America's invasion of their country and Afghani Mujahideen freedom fighters during the Soviet Union's invasion of theirs; I think he's trying to make a point about technology enhancing the capabilities of people who are in any conflict with conventionally powerful forces, not an endorsement of David Koresh.
It’s really odd how people will so easily fixate on the bone the government consisting of maniacal, narcissistic, psychopathic, pathological liars will throw them; while totally ignoring that the pathological lying, evil, murderous people in and of the government are constantly and ceaselessly, lying and murdering.
There now carpet bombing and murdering people in Iran, just like they mass murdered people in Gaza, and they’re doing it to cover up and distract from the fact that our government consists of raping pedophiles. That is who we are governed by. … but David Koresh excuses it and makes any opposition invalid, of close.
I was reading your comment and thought you were a bit too extreme, but then I thought about it and was like "Hmmm. Yes. Sounds pretty accurate actually." So yes I agree.
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:
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 girls' school that's supposedly close to an IRGC base. Still, it is mostly individual buildings or installations rather than an attempt to flatten entire areas.
I understand your compulsion to rationalize things, make excuses for your abusers, but I ask you to contemplate for a moment what you are defending. One, hopefully we have all seen the genocidal bombing of Gaza turning whole regions of large apartment blocks into an hell-scape of rubble with tens of thousands of people buried underneath them; people, not animals, not “just brown people”, not “terrorists”… people like you, like your wife or girlfriend, like your daughter or son or nephew…people who also want to live just like you even if far more humbly, without all the waste and decadence of the avg American. Should your loved ones be bombed and buried under a resort and luxury condo towers because a clan of billionaires do not like that you won’t leave your land?
Two, at the very least, the most generous interpretation, the very first strike to start an illegal war of aggression that the Nuremberg trial clearly established as the “mother of all subsequent evil”, was not only on a girls school that killed dozens and dozens of young girls, but did so in a “double tap“ process where they observed that people arrived in ambulances and parents in cars to pick up very small humans, and then they hit them again with another missile. Let us be clear about what you are excusing… They intentionally splattered the guts and flesh of young girls and their parents rushing to save them all over a 300 foot diameter blast radius.
We can lie to ourselves that may have been a “mistake“ but as established during the Nunberg trials, there is no defense in claiming that if you started the illegal and immoral war of aggression.
Three, why are they hiding what is happening if it’s all above board? Why would they not permit unfettered access showing what is being targeted bombing and that the Iranians are lying when they say that thousands of civilian structures have been bombed including schools and hospitals? You trust Hegseth? Trump? Need I say more?
And all that is without even addressing that these people have done nothing but lie and lie about lying about lying.
And let’s also remember that as shocking as the files that gave been released, they have not even released even the slightly uncomfortable parts of the Epstein Files, let alone arrested any of the rapists and pedophiles that are now on yet another murder spree, starting that prosecuting everyone would cause the whole system to collapse!
If want to believe people like that, people who do nothing but lie, rape, murder and cover up for it; then I guess there is nothing else to say and you will have to deal with that on your own as it eats you up from the inside. I for one am opposed to these types of people and actions and will speak out about it even if people don’t like it. And I refuse to make excuses for it for any reason, be it personal weakness or comfort.
> I think he's trying to make a point about technology enhancing the capabilities of people who are in any conflict with conventionally powerful forces
Which is absurd, since all the technology he used was manufactured by the conventionally powerful forces and they can decide to not sell you their stuff.
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.
What started in Ukraine, this is modern warfare. Like most "consumer" goods that are mass produced, you can now get a capable strike force for peanuts.
The russians have taken close to 1.5 million casulties because ukraine engineering for cheap drones. Putin really, really f-ed up his "3 day military operation".
We might need them. Would be better than my theory that this country will recover at some point after they destroy the EPA and reintroduce leaded gas because that's what made this country great which leads to a generation of kids who are willing to throw bricks at cops again.
> This project manifesto declares a fundamental shift: advanced air-defense capabilities—once locked behind billion-dollar state arsenals and classified labs—are now within reach of determined individuals using consumer electronics, open-source software, and rapid prototyping.
I guess a lot of people will not be happy with this xD
Check out his code. It’s a joke. His control loop is a naive proportional response that doesnt even account for error let alone interpolate trajectory. Look at rocket.txt and launcher.tx. Especially the “fusion” function. lol. Stay in school kid.
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 that take them down.
The fact that home made drones can cause such havoc to even the best funded military is an equalizer when the military with all the power is actively trying to completely eliminate the otherside.
There are no home made devices a Gazan can build that can protect from a 2000lbs bomb.
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.
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.
Really cool work on making your own rocket motors.
I wonder why he calls it a MANPADS (Man portable Air Defense System) It does slightly resemble a Manpads, but with a GPS based guidance system it would not able to be used for air defense, even conceptually. Typically manpads would use something like an infrared/optical or radar guidance system which would run way more than $5. This does seem like a cool home made AGM-176 or similar. There's always been a side project idea in the back of my head about what the cheapest IR or laser guided RC Plane launched rocket would look like. A cheap rocket design powered by some model rocket engines that could be used for a drone -> drone intercept cheaply.
Awesome job taking a fun idea into reality. It's really impressive to see the design work
Straight up admitting that it's meant to implement MANPADS is certainly a choice, I hope the author doesn't get himself in hot water.. ITAR or something..
Many mention ITAR or some other issue, nothing about this project is even close to ITAR (as far I understand), connecting camera to rocket using it as guidance will get in trouble most likely, if not mistake only thing allowed is using camera to AIM at sun.
MANPADS are certainly covered by ITAR. It could probably be effectively argued by his lawyers that what he has created isn't truly MANPADS but rather just an edgy toy that superficially resembles a weapon system but isn't actually capable of performing as one. Maybe that would work, but I think his chance of getting dragged into the legal system for this or for some chickenshit like weed possession are very high, particularly if the media at large picks up this story.
https://www.law.cornell.edu/uscode/text/18/2332g states that just having a system "intended to launch or guide a rocked or missile described in... [description of MANPAD type rocket]" carries life imprisonment. He calls it a manpad and then shows a system intended to launch it.
There is no consideration in the law whether he actually plans to use it or ever meant any violence, nor any consideration of whether it violates ITAR.
As someone who has a lot of interest in weapons law, this is probably about the only kind of weapon that can't be even legally contemplated in the USA, worst case for almost anything else you can get an NFA stamp. The USA is absolutely paranoid about yielding their air power so they come down like a ton of bricks against anyone that might want to defend against that.
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...
Fascinating, is miniaturisation and “democratisation” of offensive capabilities via 3d printing and consumer tech going to impact defensive capabilities as well?
Are we going to see foot troops carry one of these strapped to their backpacks and launched autonomously to counteract incoming drones?
It still doesn't cease to amaze me what can be done with modern ultra-cheap electronics. $1 for the accelerometer. $17 for four servos. But as DIY cheap weapon development? Only if the ultra-cheap electronics pipeline will keep flowing.
But you get more followers and that's the goal today isn't it? You have to take the good with the bad. No one is categorizing the follower ranks by "good guys" versus "bad guys" so you never know when one of your "admirers" is only there to monitor you in case you get out of line.
What the “government” has in store for you is way scarier. You just don’t know it any more than a cow on a pasture knows what a slaughter house is, yet.
I watched a YouTube video the other day about how the usa tracks missle launches globally. I would assume they have to pass a minimum threshold of power/heat/energy to be detectable.
Let’s all pray this toy project, if readily upgradable, is also trackable and well … the way we keep law and order is by actual policing and prosecuting. So hopefully this doesn’t get out of hand.
Right now, today, the US government and it's three letter agencies are being run by a club of human trafficking peodophiles and rapists. Not individual, isolated, crimes. An organized group of very twisted people, having 'immigrants' rounded up and killed, pushing women back into the 1920s, and trying to make anyone who strays from heteronormative a criminal.
Having some independent developers in the defence market is not necessarily a bad thing.
This is insanely clever—especially using a $5 sensor to adjust the rocket mid-flight. Shows how much you can do now with cheap electronics and open-source software. Curious how reliable the recalculations are under real-world conditions.
This provides a distributed camera network to provide realtime updatable telemetry for target acquisition.
Only thing missing is he should have used LoRa as the backend comms. Meshtastic devices provide encryption and full comms with mesh for cheap.
Thankfully ive already downloaded everything. I suggest you all do the same, cause this repo is getting purged and the student Alisher Khojayev at Los Angeles Valley College is likely going to get black bagged.
Be very careful. Google and GitHub will turn you over without hesitation, and everyone who downloads this will probably be vanned.
Remember kids, the warrantless search is only illegal if they don’t find a surface to air missile. Anything can be made retroactively legal if they find something like this.

No lack of entrackment data generated by digital twin of "the system".
The video references "future tracking systems," so I don't think it aims at all yet.
Yes, I don't think this project is a serious threat as a weapon, it's more interesting if viewed as a politically provocative stunt, to get people thinking about the relationship between technology and war.

Weaponized drones (say D_A) can be countered by other weaponized drones (say D_B), equally cheap or cheaper than D_A because the D_A is usually targeting something larger (so more payload) and typically has a longer range. D_B only needs to wreck D_A at a shorter defensive range. That's what Ukraine is doing.
You can also use drone swarms with coordinated action so that each drone in the swarm is only targeting one other drone, and automatic re-targeting if one node misses. [1]

I doubt it, as D_A's target is stationary (and could be reduced to GPS coords) while D_B's target is moving.
> I doubt it, as D_A's target is stationary (and could be reduced to GPS coords) while D_B's target is moving.
It's a good point, though I should point out that GPS denial is assumed in those sort of contexts as a first countermeasure so D_A likely has alternative targeting, and that smaller drones can move faster with less energy storage, which itself requires less weight, compounding the benefits of being smaller.
I don’t know if it will work, but here’s a startup that seems to be building an AI-controlled shotgun:

Given the war in Ukraine, wanting to build such things is certainly understandable. But still, this is the stuff of nightmares.
"Realistically, I doubt there’s ANY system out there will be able to counter small weaponized drones that are flown manually "
Why would lasers not work?
Those cheap drones are made from plastic, if you have a laser powerful enough and a target guidance system (like a camera and a PI) - then you would just need enough of them.
Lasers imo don't really have IRL advantages over machine guns and rockets, and their line of sight nature is a huge limitation.
Laser:
- are cheap to shoot - do not fall on someones head if they miss (unlike firing bullets and rockets at a drone that will come down again) - do hit the target immediately if aimed right
Problems with lasers are, cooling, power consumption limiting mobile use - and indeed targeting and fog and clouds.
At long distances the small cross section of the drone requires tight focusing (expensive optics) or a high power, preferably pulsed laser (expensive laser) or both.
Not impossible but many times more expensive than the drone
Expensive is fine since it is reusable.
Lasers won’t effectively work, it’s a two part equation, detection and targeting. To neutralize a target using a ground-based laser, you need an enormous power, and still it won’t penetrate a high distance/altitude in the sky, environment factors also to be considered. The detection part is even harder, these small 8in drones are almost impossible to detect unless you can hear it, aka it’s over, because they can fly at 250km/h, too small to be visually detected, acoustic sensors will fail to detect them, and radar will miss it as a false negative since it’s the size of a bird. I have seen some systems trying to combine all that to detect them plus AI for flying pattern detection, but they are far from being reliable in practical applications.
Unless you mean it just can't detect objects that small, my guess is we'll see things calibrate toward a lot more birds being cooked in active war zones vs drones with explosives being let through.
The small weaponized drones do not fly 250 km/h.
Yes, but they still approach in just a few seconds.
"let alone with AI" what's falling into the AI category here perhaps is the key question, since microseconds counts, and LLM are very slow!
Even the fastest "real-time" LLM frameworks currently report sub-second latencies around 120ms. This is fine for high-level mission planning (e.g., "fly to the red house") but too slow to prevent a drone from hitting a tree at 50mph (80 KM/h)[1]
Whilst the Shahed-136 kamikaze drone typically flies at a maximum speed of around 185 km/h (roughly 115 mph or 100 knots).

> "let alone with AI" what's falling into the AI category here perhaps is the key question, since microseconds counts, and LLM are very slow!
LLMs (Large Language Models) are far from the only type of AI around. It's a pretty broad field, and there are real-time AI systems, for example, self-driving cars, which have the response times you're thinking of. [1]

What kind of systems are you thinking about? Jet airplanes for sure are completely safe from small drones.
"Jet airplanes for sure are completely safe from small drones."
That feels like a bold and unsupported assertion. Ask a pilot how they'd feel about takeoffs or landings through airspace filled with adversarial drones.
maybe in the air, but I seem to recall the Ukrainians being successful at attacking Russian planes on the ground.

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 electronics and mil-spec capability keeps shrinking and this is a pretty stark demonstration of where that trend leads. A few years ago this would have required an IMU that cost more than this entire build. The democratization angle cuts both ways though - the same accessibility that makes this cool for hobbyists makes it genuinely concerning from a proliferation standpoint.
> The gap between consumer electronics and mil-spec capability keeps shrinking
My friend's brother works in munitions and had, in his spare time, designed and prototyped a missile that could be built for about 10k. He pretty much was ignored by the contractor he works for.
Shockingly, as of a couple weeks ago, they are all hot and bothered to talk.
I wonder what could have possibly sparked that... lol
Cheap sensors look impressive in demos but drift and calibration wreck repeatability unless you babysit launches so nobody in defense is sweating this yet.
For a sub-minute flight the drift budget is actually pretty forgiving — a MEMS gyro drifts maybe 1-3 deg/sec, and if you're fusing with accelerometer data you really just need "which way is up" and "am I still pointed at the target." A $5 IMU can hold that for tens of seconds.
Where you're right is repeatability. Mil-spec works the same on launch 1 and launch 500 across temperature extremes. Consumer MEMS you'd need to characterize each unit individually — fine for a demo, impractical at any scale.
You can calibrate any sensor, its just a manufacturing step, and while cheap ones may be inaccurate and drift over time, I'm pretty sure the good enough ones (which cost tens of dollars, not fractions of a dollar) are accurate enough to work for the seconds-to-minutes flight time of a rocket like this.
They should be sweating, because if the other side can fire 100 rockets for $10k that are close enough to not immediately and obviously be off target, and you don't know whether a more expensive one with actual explosives is hiding within that barrage, you now have 100 targets to try to intercept, and suddenly your costs have gone up dramatically while the other sides costs has barely moved.
100 rockets for $10k is not happening. The price floor is not dictated by the electronics (which did get cheaper), it's dictated by the rest of the system: propulsion, warheads, arming and safety, QA, traceability, climate and shelf life stability.
Take a look at Raytheon's manufacturing line: https://www.youtube.com/watch?v=kCCkVAHSzrc That's what it takes to have missiles that are nearly guaranteed to perform to specification every time. You can stockpile the packaged missiles in a non-climate-controlled shed for years, replenish them at sea while being showered with salt water, subject them to shock of a nearby blast while in a VLS, and they will still launch, go up to Mach 13, and catch an incoming ballistic missile nearly every time.
Sure, Iran's ballistic missiles are simpler than SM-3, but they are still subject to most of the constraints. They still need perfectly cast large size solid rocket motors that don't crack after being stored for a year, they need warheads that only go off when they are supposed to, they still need to trace every part for QA, etc. There's a vast gap, largely invisible to amateurs, between garage prototypes and stockpiled AURs.
TFA is literally about a $96 rocket.
> propulsion, warheads, arming and safety, QA, traceability, climate and shelf life stability.
You're entirely missing the point.
These do not need to be reliable for the scenario I hinted at. They need to be large enough that if one of them is a higher quality rocket (not part of the $10k) that contains actual explosives, you have serious destruction on your hand. Maybe something that looks large enough for that will drive the cost up and we're talking $20k or even $100k instead of $10k.
The precise cost is largely irrelevant, as long as the total cost is a tiny fraction of the cost of a missile interception.
The point is you'd be multiplying the cost assymmetry by forcing a massively outsized response. Because if you don't try to intercept them, every future barrage will include a real rocket. If you do try to intercept them all, you'll be burning through massively expensive interceptors to take out a bunch of cheap toys.
If I was ever considering an insurgency, or a war, I'd be stocking up on vast quantities of toys.
For different definitions of cheap though.
While the pure gyro/accelerometer stuff does suffer from major problems the improvements in SLAM using just cameras in the last 15 years are insane.
Visual SLAM on a rocket would be wild. The frame rates you'd need at those velocities are brutal though — feature tracking falls apart fast when your entire visual field is changing at hundreds of m/s. Drones are the sweet spot where camera-based nav really shines.
But do they drift enough to hit girls schools?
I think the problem sits in the white house, not in the sensors.
Oof
Ask Claude
It's not really terribly new actually, in the past, rapid advances in consumer technology have enabled other sort of weapon guidance systems. For instance, the development of extremely compact television cameras available to consumers directly lead to the development of the Walleye television bomb. It happened when one nerdy guy was fucking around with his new camera and realized that he could automatically track track features in an analogue television signal using some quite basic analogue electronics. Point the camera into the general direction of the target and you can then "lock on" to some target feature and based on contrast it could tell how that feature was moving around in the image.
He implemented a 1D tracker in his garage, took it to work and showed people. A few years later these bombs are taking out bridges and even sometimes hitting moving trucks.
People made self-guided missiles with 1940s technology, in the 1940s. It can't be too much of a surprise if someone right now can make guided missiles in their garage with 2026 electronics. At this point the "guided" feature is trivial, the "missile" part is doable, and the weapon has probably become the tricky part.
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.
The restrictions on GPS prevent ballistic missiles, not MANPADs. Typical limits are 515 m/s and 18,000 meters (try using your phone's GPS on a commercial flight, it works fine near a window). Update rate is probably the biggest issue with GPS and MANPADs.
What you are likely thinking of is the "selective availability" system, which intentionally provided slightly inaccurate data to civilian clients, while military receivers could decrypt the most accurate info. But this has not been used for many years now.
Other than that, GPS is a one-way system, it does not know you exist, how fast your receiver is moving or "give" different information to one client vs another.
Even if it did, this is essentially a toy and moving slower and lower than a general aviation plane.
It uses accelerometers and other sensors because they can be sampled and integrated hundreds of times a second. The $5 gps module is 9600 baud serial and provides one update/second (or maybe 5/sec depending on which part number you pick).
No, he's thinking of the "CoCom limits". It's built into the receiver.
There's a lot of room within those 18km/59000ft and 1000kts/1200mph limits.
Chinese GPS chips dont have those restrictions.
I even have 1 that can remove up to 8 active jamming signals.
Gotta love what you can buy for $20
It would be interesting to see if those are only for external sale vs restricted for sale within China.
If China allows those unrestricted chips to be sold internationally but not domestically it would be a strategic long-term decision, I would think. Destabilize the neighbors but not themselves.
The more likely reason is that their government has simply not gotten around to restricting it.
More than the electronics, I would be curious about the performance of 3d-printed plastic parts on a rocket. Are they strong enough?
> A few years ago this would have required an IMU that cost more than this entire build.
Are you sure about this? MEMS IMUs have been popular and cheap for ~10-15 years.
Owning a system designed for surface to air weapon carries life imprisonment any USA, without any intent for violence, just simple possession or conspiracy to possess[]. Doesn't even matter if you have an NFA stamp, there is no exception except if it's done with authorization and behalf of the government.
Merely having a device intended to guide the rocket is also the same penalty.

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.
> The video ends with shots of Russian drone war, and, bizarrely, photos of David Koresh.
You're omitting that the end of the video also features pictures of Martin Luther King, Vietnamese civilians during America's invasion of their country and Afghani Mujahideen freedom fighters during the Soviet Union's invasion of theirs; I think he's trying to make a point about technology enhancing the capabilities of people who are in any conflict with conventionally powerful forces, not an endorsement of David Koresh.
It’s really odd how people will so easily fixate on the bone the government consisting of maniacal, narcissistic, psychopathic, pathological liars will throw them; while totally ignoring that the pathological lying, evil, murderous people in and of the government are constantly and ceaselessly, lying and murdering.
There now carpet bombing and murdering people in Iran, just like they mass murdered people in Gaza, and they’re doing it to cover up and distract from the fact that our government consists of raping pedophiles. That is who we are governed by. … but David Koresh excuses it and makes any opposition invalid, of close.
I was reading your comment and thought you were a bit too extreme, but then I thought about it and was like "Hmmm. Yes. Sounds pretty accurate actually." So yes I agree.
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 girls' school that's supposedly close to an IRGC base. Still, it is mostly individual buildings or installations rather than an attempt to flatten entire areas.
Not carpet bombing, yet. Israelis said the same at the start of the most recent Gaza war, which ended with large neighborhoods being destroyed.
They are using white phosphorus on populated areas in South Lebanon. That's as vile as one can get.
Be that as it may, carpet bombing has a specific meaning, and it's not bombing one's not on board with.
In the context of Iran I agree with you.
Not so sure about South Lebanon. From whatever media coverage I saw, some look not that different from carpet bombing.
Evidence for the claim?
Human Rights Watch claim it, and have analysed photographs put on social media
https://www.hrw.org/news/2026/03/09/lebanon-israel-unlawfull...
(they have also previously documented that Israel has done this in the past)
https://share.google/aimode/CoVNoZcR3YOotyg5o
I understand your compulsion to rationalize things, make excuses for your abusers, but I ask you to contemplate for a moment what you are defending. One, hopefully we have all seen the genocidal bombing of Gaza turning whole regions of large apartment blocks into an hell-scape of rubble with tens of thousands of people buried underneath them; people, not animals, not “just brown people”, not “terrorists”… people like you, like your wife or girlfriend, like your daughter or son or nephew…people who also want to live just like you even if far more humbly, without all the waste and decadence of the avg American. Should your loved ones be bombed and buried under a resort and luxury condo towers because a clan of billionaires do not like that you won’t leave your land?
Two, at the very least, the most generous interpretation, the very first strike to start an illegal war of aggression that the Nuremberg trial clearly established as the “mother of all subsequent evil”, was not only on a girls school that killed dozens and dozens of young girls, but did so in a “double tap“ process where they observed that people arrived in ambulances and parents in cars to pick up very small humans, and then they hit them again with another missile. Let us be clear about what you are excusing… They intentionally splattered the guts and flesh of young girls and their parents rushing to save them all over a 300 foot diameter blast radius.
We can lie to ourselves that may have been a “mistake“ but as established during the Nunberg trials, there is no defense in claiming that if you started the illegal and immoral war of aggression.
Three, why are they hiding what is happening if it’s all above board? Why would they not permit unfettered access showing what is being targeted bombing and that the Iranians are lying when they say that thousands of civilian structures have been bombed including schools and hospitals? You trust Hegseth? Trump? Need I say more?
And all that is without even addressing that these people have done nothing but lie and lie about lying about lying.
And let’s also remember that as shocking as the files that gave been released, they have not even released even the slightly uncomfortable parts of the Epstein Files, let alone arrested any of the rapists and pedophiles that are now on yet another murder spree, starting that prosecuting everyone would cause the whole system to collapse!
If want to believe people like that, people who do nothing but lie, rape, murder and cover up for it; then I guess there is nothing else to say and you will have to deal with that on your own as it eats you up from the inside. I for one am opposed to these types of people and actions and will speak out about it even if people don’t like it. And I refuse to make excuses for it for any reason, be it personal weakness or comfort.
> I think he's trying to make a point about technology enhancing the capabilities of people who are in any conflict with conventionally powerful forces
Which is absurd, since all the technology he used was manufactured by the conventionally powerful forces and they can decide to not sell you their stuff.
The fact that Koresh and his group held off Federal officers who stormed their building with simple guns that anyone can buy, is likely the point.
Out of five and a half minutes of video, David Koresh appears for perhaps three seconds.
It does put a new twist on the recent controversy about 3d printers needing to be licensed, however.
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
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.
Yes. Both sides are using explosive FPV drones, flown directly into soldiers (as well as other forms of drone warfare.)
thank you. that was unnerving to watch.
Yeah, this genie is well and truly out of the bottle.
What started in Ukraine, this is modern warfare. Like most "consumer" goods that are mass produced, you can now get a capable strike force for peanuts.
The russians have taken close to 1.5 million casulties because ukraine engineering for cheap drones. Putin really, really f-ed up his "3 day military operation".
Who knew there were war bros.
We might need them. Would be better than my theory that this country will recover at some point after they destroy the EPA and reintroduce leaded gas because that's what made this country great which leads to a generation of kids who are willing to throw bricks at cops again.
So this is basically a DIY mini rocket clearly advertised to be used in an asymetrical war. I do not expect this project to remain on github for long.
> This project manifesto declares a fundamental shift: advanced air-defense capabilities—once locked behind billion-dollar state arsenals and classified labs—are now within reach of determined individuals using consumer electronics, open-source software, and rapid prototyping.
I guess a lot of people will not be happy with this xD
> Description: Space echoes like an immense tomb, yet the stars still burn. Why does the sun take so long to die?
Translation: everyone should be able to shoot down an airliner, not just nations.
I mean, if we already "trust" nations with that power...
Check out his code. It’s a joke. His control loop is a naive proportional response that doesnt even account for error let alone interpolate trajectory. Look at rocket.txt and launcher.tx. Especially the “fusion” function. lol. Stay in school kid.
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 that take them down.
I would invert that statement.
The fact that home made drones can cause such havoc to even the best funded military is an equalizer when the military with all the power is actively trying to completely eliminate the otherside.
There are no home made devices a Gazan can build that can protect from a 2000lbs bomb.
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.
My understanding is that for the civilians in Ukraine Shaheed style drones are the danger.
>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.
Really cool work on making your own rocket motors.
I wonder why he calls it a MANPADS (Man portable Air Defense System) It does slightly resemble a Manpads, but with a GPS based guidance system it would not able to be used for air defense, even conceptually. Typically manpads would use something like an infrared/optical or radar guidance system which would run way more than $5. This does seem like a cool home made AGM-176 or similar. There's always been a side project idea in the back of my head about what the cheapest IR or laser guided RC Plane launched rocket would look like. A cheap rocket design powered by some model rocket engines that could be used for a drone -> drone intercept cheaply.
Awesome job taking a fun idea into reality. It's really impressive to see the design work
Straight up admitting that it's meant to implement MANPADS is certainly a choice, I hope the author doesn't get himself in hot water.. ITAR or something..
(Would be cool to see an ATGM variant too!)
As the YouTube comments say:
> This guy really wants that defense contract.
They may just give it to him to buy him. It’s the first stage of neutralizing the peasantry of rebellious thoughts against the aristocracy.
Many mention ITAR or some other issue, nothing about this project is even close to ITAR (as far I understand), connecting camera to rocket using it as guidance will get in trouble most likely, if not mistake only thing allowed is using camera to AIM at sun.
https://www.youtube.com/@LafayetteSystems is similar project, also by actual defense contractor, and less opensource.
MANPADS are certainly covered by ITAR. It could probably be effectively argued by his lawyers that what he has created isn't truly MANPADS but rather just an edgy toy that superficially resembles a weapon system but isn't actually capable of performing as one. Maybe that would work, but I think his chance of getting dragged into the legal system for this or for some chickenshit like weed possession are very high, particularly if the media at large picks up this story.
https://www.law.cornell.edu/uscode/text/18/2332g states that just having a system "intended to launch or guide a rocked or missile described in... [description of MANPAD type rocket]" carries life imprisonment. He calls it a manpad and then shows a system intended to launch it.
There is no consideration in the law whether he actually plans to use it or ever meant any violence, nor any consideration of whether it violates ITAR.
As someone who has a lot of interest in weapons law, this is probably about the only kind of weapon that can't be even legally contemplated in the USA, worst case for almost anything else you can get an NFA stamp. The USA is absolutely paranoid about yielding their air power so they come down like a ton of bricks against anyone that might want to defend against that.
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.
> rocket propellant
You can homemade it, kno3+sugar
Fascinating, is miniaturisation and “democratisation” of offensive capabilities via 3d printing and consumer tech going to impact defensive capabilities as well?
Are we going to see foot troops carry one of these strapped to their backpacks and launched autonomously to counteract incoming drones?
https://news.ycombinator.com/item?id=47370362
It still doesn't cease to amaze me what can be done with modern ultra-cheap electronics. $1 for the accelerometer. $17 for four servos. But as DIY cheap weapon development? Only if the ultra-cheap electronics pipeline will keep flowing.
Given the navigation is done by the cameras (not GPS) you will also need to do some work with the second repository (by the same guy)-

> God, I feel like I am going to be on a list after clicking that link.
It's a poor life that doesn't put you on a few such lists!
What the “government” has in store for you is way scarier. You just don’t know it any more than a cow on a pasture knows what a slaughter house is, yet.
But in Canada we ...
Oh shit. You're right.
I watched a YouTube video the other day about how the usa tracks missle launches globally. I would assume they have to pass a minimum threshold of power/heat/energy to be detectable.
Let’s all pray this toy project, if readily upgradable, is also trackable and well … the way we keep law and order is by actual policing and prosecuting. So hopefully this doesn’t get out of hand.
Very impressive, but very troubling.
Right now, today, the US government and it's three letter agencies are being run by a club of human trafficking peodophiles and rapists. Not individual, isolated, crimes. An organized group of very twisted people, having 'immigrants' rounded up and killed, pushing women back into the 1920s, and trying to make anyone who strays from heteronormative a criminal.
Having some independent developers in the defence market is not necessarily a bad thing.
Isn't it obvious that, if one person can do it, many more can do it as well, and probably have? It's not like they'll put it on GitHub.
This thing doesn't do anything a launcher from the 70s couldn't do.
Global detection is for balistic missiles, not things launched by human portable devices
This is the coolest thing I've seen all week, possibly this month
This is insanely clever—especially using a $5 sensor to adjust the rocket mid-flight. Shows how much you can do now with cheap electronics and open-source software. Curious how reliable the recalculations are under real-world conditions.
Kid knows how to advertise
Yes to three-letter agencies.
I hope the kid is aware that he better not commit anything even remotely like a crime, because they will try to stitch him up quick.
Sounds a lot more like a missile than a rocket.
The HN headline is very euphemistic, but his own published materials aren't. He's openly saying it's a missile.
Impressive! Well done
So basically a homing missile?
Glad he’s in the US, I remember reading in Canada few months ago students got criminally charged for building and testing an anti-drone system.
And what this misses is with his other repo https://github.com/novatic14/Distributed-Camera-Node-Trackin...
This provides a distributed camera network to provide realtime updatable telemetry for target acquisition.
Only thing missing is he should have used LoRa as the backend comms. Meshtastic devices provide encryption and full comms with mesh for cheap.
Thankfully ive already downloaded everything. I suggest you all do the same, cause this repo is getting purged and the student Alisher Khojayev at Los Angeles Valley College is likely going to get black bagged.

Insanity. Airbus fighter jets, open-source rockets on github...

that's lit
Airbus has been in the defense industry for a long time.
And the deadliest weapons in war today are repurposed toys.
I’m waiting for the open source EW project that attacks the uplink. Now that would be a fun competition.
And then the rocket maker pivot back to control by wire, as in the drone sphere. DIY TOW when?
Be very careful. Google and GitHub will turn you over without hesitation, and everyone who downloads this will probably be vanned.
Remember kids, the warrantless search is only illegal if they don’t find a surface to air missile. Anything can be made retroactively legal if they find something like this.
Its scary that you can whip something like this in under 100 bucks. Add a small warhead and you got a small missile.
Like we see in Iran, with trumps idiotic war the US cant even protect its allies and own soldiers, even with a whopping 1.5 trillion budget.
So you are going to see the following cope
Coper: But it's sensors are so low end it will never be reliable enough. Response: We can use AI to make up for low quality sensors, we can add a camera if we want it to be as reliable as self driving cars for a small amount of money Coper: AI what a joke that doesn't work Response: It's live in production Coper: But you can't fit a big enough payload Response: Lets see
