Reminds me of a 2014 work by MIT on extracting audio signals from vibrations of objects in a video [0] which I found was truly fascinating. I guess someone was paying attention to bring this to production mode out of the lab.

- lioeters 6y agoIndeed this is a very interesting artifact, the fact that it was designed by Léon Theremin, and the technical know-how that went into it. > Because it was passive, needing electromagnetic energy from an outside source to become energized and activate, it is considered a predecessor of radio-frequency identification (RFID) technology.
- seesawtron 6y agoWhat a beauty! "The Thing" was designed by Soviet Russian inventor Léon Theremin, best-known for his invention of the theremin.
- johnnythunder 6y agoIf you want to even further back you can look at the side channel attacks shown in person at the CanSecWest conference in 2009 - https://cansecwest.com/csw09/csw09-barisani-bianco.pdf https://cansecwest.com/csw09/csw09-barisani-bianco.pdf The most interesting part might be the frequency analysis that was done after getting the signal. It was amazing to see the words get decoded in real-time.
