Jeff Thomas WWVB clock modification

[Terry S]

Guys, thinking about modifying my big beautiful Jeff Thomas clock. The original Atomix clock movements are hard to find, and in my area WWVB reception is very spotty (and I have a metal roof).

Here is the clock schematic:

I think with just a little rework, I could modify the design to talk to an Arduino. I'd have all the counters reset to zero from the Arduino, and then have the Arduino clock the counters  until they catch up to the current time as grabbed from the web via WIFI. I can handle the hardware design and the rudimentary code that would be required to reset and clock the counters, but I'm definitely going to need help with the WIFI and time retrieval portion.

Anyone willing to lend a hand from that standpoint? My code skills are, as I implied, crude at best. I would need advice on selecting a WIFI shield as well.....

Open to other ideas too.

And another option might be to just have the Arduino emulate the WWVB receiver function. I'd have to supply it 5V instead of 1.5V. Just spitballin'.

Speaking of Atomic clocks... I have two Heathkit GC-1000 "Most Accurate Clock"  complete with the original manual.  

* One of them has some mods too.  I have been unable to get either  one working.

I can post pics if you guys want!

I already have similar code I used for a different clock.  Email me direct with contact info if you can.
