Hi,
has anybody tried a setup like this:
- The tower sends a message to the RCX.
- The RCX beeps.
- The beep sound is captured by two microphones on two neighbouring corners
of the navigation space.
- Their signal is fed into a stereo soundcard.
- The computer finds the begin of the signals, computes the delays
and from them the position.
- The computer sends the position to the RCX.
- Repeat.
