Ethernet over tin can phones

The goal of this project is to get a data transfer going, over a tin can phone, and ultimately play Quake over a tin can phone. Because we can. Hopefully.

A tin can phone

Plan of attack

  • Use a TUN/TAP device, probably controlled from Python.
  • Use two tin can phones in a unidirectional manner to avoid half-duplex.
  • Use a speaker and microphone at each end.
  • Encode packets in sound, maybe something Manchester code. (The soundmodem software package is more or less what we want)

FIXME: We can probably only control the frequency and duration of the sound from software, is this what we want? FIXME: How do we analyse the sound from the microphone?
