I'll make a video at some point, but it's just an Oscilloquartz 8663-xs that I mounted in the box with connections for power and 10MHz. I got the OCXO unit from eBay.
This has led me down a rabbit hole. Now I am thinking I may need an GPSDO NTP server with a 10MHz sine input fed with a rhodium frequency standard. I want all my logs to be picosecond accurate. :) Mostly just because I can.
