From hard drive to over-heard drive: Boffins convert spinning rust into eavesdropping mic


Re: I'll file this in the ...

It might be worth watching out for capacitance and impedance also. I used to work on the servo-writers that create the tracks used by hard drive PES systems, and the capacitance gauges we used to error-map them were capable of picking up a lot of other stuff. Maybe it's possible to turn a touchscreen into a microphone.
