$96 3D-printed rocket that recalculates its mid-air trajectory using a $5 sensor(github.com)

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.

Kid knows how to advertise

Yes to three-letter agencies.

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.

Well that doesn't bode well for the coming world war :(

This is the coolest thing I've seen all week, possibly this month

This isn’t a serious project, in the terms of something that will disrupt warfighting. It’s basically a resume to work as a junior engineer at Anduril.

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.

A word to the wise: don't design weapons and share them publicly on the Internet.

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.

Very cool project. The combination of 3D printing and low-cost sensors has really changed what's possible for experimental rocketry.
