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.
