Two students in Berlin worked together to hack a knitting machine from the ’70 so that it records your voice onto a sweater. All you have to do is just say a message into a microphone and the frequency of your voice is analyzed by a computer and is turned into binary code that the machine will use to control 24 servo-motors which will turn your words into a knitted pattern. The pattern doesn’t just depend on the words but it varies also according to your modulation, so whether you are dull and monotone or loud and yelling. The only problem is that no one will understand your message, well maybe a few engineering students.
