Hello and Merry Christmas,
I made an embedded (S)NTP server. The software is still under
development and will eventually include a low-grade GPSDO but right now
even the simplistic algorithm is working quite well so I figured I'd share.

This is a low-level microcontroller implementation, there is no OS nor
ntpd in the traditional sense. Just enough logic to keep time using the
incoming PPS and timestamps, and a tiny VCXO to discipline. It's no
Thunderbolt and there is no clock output but it should be fantastic at
NTP. Before too long I will have adapters for connecting to Oncore
GT+/UT+ (and maybe M12, haven't checked) as well as Trimble Resolution T
and Resolution SMT using a ribbon cable instead of the jumper wires.
All open-source hardware and software. Pictures, details, and design
documents are in the eevblog thread. I'll let you all know if and when
I'm ready to sell them, for now I just wanted to show what I've got.
