reminded of mordechai guri (from ben-gurion uni) whose whole dept just keeps popping out side channel attacks year after year, but most of them are in "the coil sits in the plate under the bagel (also ignore the PCB for data decode)" field of capacity (exactly because of noise etc)

I mean, some legitimately interesting research on its own in this field - the stuff about cpu states through power sidechannel (most desktop/laptop PSUs are non-filtering and not isolated, so you can reverse-observe cpu state from minute differences on supply side) and such are pretty neat! impractical as fuck, but neat
