If I understand this correctly, this is a paper about 3D printing physical objects, with no electronics, that send information over wifi.
This is magic.
@ajroach42 not really sending information over wifi (backscattering, producing radio signal that doesn't really have anything to do with wifi), but yeah, magic.
I'm curious how well it works, and what is involved on the receiver end (haven't read the paper yet)
According to the video, the goal is for the backscattered signal to interact with wifi receivers, unless I'm misunderstanding something.
This is a small personal instance running on a couple small ARM servers at home.
