Something happened to the previous....

As mentioned on my Web page:


you can use a cheap module from eBay, or perhaps an Adafruit one, and 
you could need a TTL to RS-232 voltage level converter:


I found that the PPS signal was OK at TTL level.

The Leo Bodnar unit would be ideal as a central server for a small group 
or bigger, and has the advantage of excellent support.  The cost is 
appropriate for the quality level of the unit, but it would likely be 
overkill for a single PC.
