alt Hacker Newsi've recently had youtube randomly suggest me a video where this dude was building his own opensource manpads, with a single rocket costing under $100 in parts (there was no explosive payload so that makes it just a rocket and not a missile, i guess). not long after, someone posted it here on hn but i think it's been removed (by the mods, i imagine) since.
i find these projects both fascinating and terrifying. seeing a single person building what normally involves huge defense corporations and government contracts, these things in their bedroom is amazing. it shows how information wants to be free and how ingenious people can get with whatever motivates them.

The knowledge and skill in the HPR (high power rocketry) hobby is definitely there to build basic weapon systems. Active stabilization using movable fins is a thing, onboard gps and flight controllers are also a thing. Nobody puts it together end to end though because it gives the whole hobby a bad look and the hobby governing organizations strongly discourage it too. Also, fortunately, most people have no interest in mass murder either. Much of the hobby is old engineers who are retired but still want to work on engineering projects in their garage.
It was here on HN (441 points)

Is there a parts list?

Seems to have almost as many comments as points, so guessing it got pushed down the frontpage list because of the "anti-flame-war" thingy HN has.
