[time-nuts] World's most precise.... wall clock

[DM]

Here are a few online projects for GPS-controlled clocks. Most (all?) have a PIC or Arduino to run the clock and sync to GPS time.

DIY projects are easy to find with Google: 
The search string I used was: gps digital clock kit OR diy OR build 

There are a number of clocks with Nixie tube displays also; just add "nixie" to the Google search string. 

Good luck

Hi! 

I have a perhaps silly question. I want to take an inferior medium (our 
eyes) and give it something attractively precise to look at. Is there such 
a thing as a digital (wall) clock with a 1PPS/10MHz/etc. input? I see that 
some clocks have GPS antenna inputs, but I want to take a GPSDO and hook it 
up to a digital clock. Purely for fun, as a mini project for myself while I 
build my bigger clocks. 

Maybe one day I'll make this work with a grandfather clock. 

Thanks, 

Eamonn
