$96 3D-printed rocket that recalculates its mid-air trajectory using a $5 sensor
https://github.com/novatic14/MANPADS-System-Launcher-and-RocketThe 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.
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 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.

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?
No lack of entrackment data generated by [edit] d̶i̶g̶i̶t̶a̶l̶ ̶t̶w̶i̶n̶ github repo of "the system".
The other part is the limited production runs. Until last month, the DoD was generally purchasing ~100 of these annually. There's no scale economy in making these, so those 100 missiles need to support the entire production & R&D of the product.
Also if you want to harden the rocket against EMP attacks you need an inertial guidance system, and those things also demand extreme precision.
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 rocket 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 don't want to use it for war. I think it would be a pretty cool technical project (if it works).
What nonviolent application are you imagining for a gps-guided rocket that is launched by pulling a gun trigger on a hand held mount?
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.
‘Easy to ignore’ is not a term I would use here, especially given the motion environment of a rocket. It seems like it might be beginning to be borderline possible.
False, given how noisy MEMS IMUs are, and the accuracy required. Even Ring Laser Gyros drift quickly.
I saw this pop up alongside its video thumbnail and nearly shit myself watching it and going "damn, that looks exactly like what's on those RU/UA drones going at each other"... https://www.ebay.com/itm/197224214645
"HS AI Vision Cube For Ultra-long-range Target Recognition tracking & Thermal" for as low as $175. I am feeling the potential ITAR violations straight through my screen.
And possibly landing on all kinds of watch lists.
I wouldn’t be surprised if some of the sellers there are just honeypots.
A name like “Ultra-long-range Target Recognition tracking” just screams “Hey, FBI, please come visit me and ask what I am building in the basement”
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.
hardest issue as I mentioned in another comment is detection. Now on using other drones to counter a drone, there are other issues, as I built and tested some before, assuming you got the detection part done. The first one is guidance and correction mid-air, flying manually won’t really be practical due to the need for an extraordinary flying skills, which can’t be relied on in the field, the second part is the speed, you need to ALWAYS make sure the interceptor is faster to catch it up, third is the weight, I disagree about the payload part you mentioned, I have seen videos of light weight drones failing to wreck bigger ones, if you are relying on collision alone. Additionally, the telemetry/video/C&C for the interceptor, if jamming is already in place, your counter won’t work either.
The swarm will require a low latency comms link, centralized or decentralized, if the area is jammed, it won’t work. i have built a self-healing decentralized system using cellular in each drone, but that’s useless if the network is down to start with.
So they might work in a very specific use case, but not an ultimate solution to counter them.

Given the war in Ukraine, wanting to build such things is certainly understandable. But still, this is the stuff of nightmares.
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.
Not impossible but many times more expensive than the drone
At that point might as well spend the money to use a kinetic weapon with basic tracking and ballistic calculations.
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).

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.
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.
Until they land then, due to their cost, they become a very juicy target to aim for.
I guess a lot of people will not be happy with this xD
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.
https://www.youtube.com/@LafayetteSystems is similar project, also by actual defense contractor, and less opensource.
Nowadays you can even use the LSM6DSV320X which has both a low-g and high-g integrated which basically obsoletes the high-g ADXL375 and saves some space, but it's not quite at the price and supply reliability of the LSM6DSOX since it is less than a year old.
(Would be cool to see an ATGM variant too!)
> This guy really wants that defense contract.
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
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...
Are we going to see foot troops carry one of these strapped to their backpacks and launched autonomously to counteract incoming drones?

I grew up building homemade rocket engines to power model rockets. I even programmed a flight computer in ASM.
I was always quite risk averse and, then being only shortly after 9/11, I told my friend I worried what we were doing may be illegal or otherwise get us in trouble. So he picked up the phone and called the county fire marshal. My friend explained EXACTLY what we were doing, down to the potassium nitrate and the homemade black powder and nitrocellulose igniters. The fire marshal paused for a long moment and said “it’s not against any law I’m aware of. Just don’t start any fires.” We proceeded to have many successful flights and participated in NERF (a rocketry club that used to get 12kft clearance from FAA before the govt started stonewalling us).
I feel very fortunate to have grown up in an environment where that was permitted. I fear that my children will not have the same privilege—for many reasons, but one factor is people putting violent things like this on GitHub. Please take it down.
The future is scary
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.
Interesting stuff, neat project, nothing new at all here except his multi camera sensing, which isn’t new but his implementation is interesting.
IDK if maybe it’s a political statement or some kind of obtuse sarcasm, but it seems like he drank way too much of his buzzword cool-aid lol. It’s probably just a job application though.
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.
And then the rocket maker pivot back to control by wire, as in the drone sphere. DIY TOW when?
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.
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.
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
