It is exciting to know a secret no one else does. David vs Goliath stories have always been powerful. It is seductive to think you have outsmarted the rest of society. Be careful who you let manipulate those emotions.

You get that the post you're replying to is saying that the idea that you have knowledge that few others do is appealing and can lead to bad decision making, right?

Ascribing evil to someone who is trying to make a point in the gentlest and most respectful way possible makes you look like a crazy person, btw.

God, I feel like I am going to be on a list after clicking that link. The future is scary

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.

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…

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.

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…

Not carpet bombing, yet. Israelis said the same at the start of the most recent Gaza war, which ended with large neighborhoods being destroyed.

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...

> rocket propellant

You can homemade it, kno3+sugar

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.

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.
