Hello 50 & 60 Hz nuts,

The recent discussions here on measuring the mains frequency and
phase prompted me to revive an experiment I set up some 3 years ago.
Live data about the phase and frequency of the 50 Hz mains here in
the Netherlands can now be viewed at:
  http://websdr.ewi.utwente.nl:8901/lichtnet/

The system consists of a simple circuit to feed the mains signal
safely into an RS232 port (using a neon bulb and a phototransistor;
the schematic is on the web page), and some cobbled-together
software running under Linux.

Regards,
  Pieter-Tjerk
