The ES-100 uses SIO or one of the similar 2 wire type I/O interfaces. Should
be easy on a Pi, but I don't have directions. I don't know how to do it on a
PC.

That's interesting.
WWVB reception would be very dodgy here - I live about 30 miles from
Dr. Mills's digs in Delaware and while while that is mostly westward
distance it's not by enough. Too bad - if I thought I could get signal
here I'dvbe very tempted to do a Pi-based receiver build to complement
my GPS-based one.

He does some nifty time hardware and software. I tried using his
suite of applications for getting it working, but had no luck - I
think largely just due to the weak signal, I'm in the outlying SF
bay area. I was able to verify the PPS was just barely being
received with the use of a little micro-oscilloscope, but that was
as far I was ever able to get....<br>
