We’ve seen a few odd ways to transfer data before (see sound transfer over lasers) but this is probably the most bizarre. Instead of using a USB drive, this man decided to invent his own file transfer method by using his sound card to send morse code-like messages representing 1′s and 0′s. This guy definitely deserves some geek street cred for coming up with this.
How it works:
The author says generating and transmitting sound out is the easy part while interpreting the sound via a microphone attached to another computer is quite difficult. Check out the full documentation and how to.
How it works:- For every character:
- For every bit:
- Send a short pulse if the bit is 1.
- Send a long pulse if the bit is 0.
- Send a silence.
- Send a very long pulse (4 times as long as the shortest pulse).
- Send a silence.
