The timing rabbit hole goes deep...

GNSS antenna installed—thanks to Dad for the help! Took a while to get everything ready, including the lightning protection (to be improved further), KF7P cable entrance box, and everything else.

2nd part of my 2025 Time series will be coming soon...ish. Once I figure out how to make more time.

Me: has GPS-synced time server for his house Also me: still struggles to get anywhere on time

It’s about time, Jeff.

Also helps make sure the building isn't moving.

That's awesome! Assuming this is an NTP server and now I want to make one quite badly

I am a service electrician in 4 office towers. We did a fire alarm verification last night, and at the end, the engineer noted that the PC running fireworks was out of sync with the time. As this system has to be air gapped, it is not connected to the internet and doesn't have the ability to get a time signal. I am going to propose building a pi NTP server for each, solving the problem. All because you showed me it is possible.

Thank you for your tireless efforts and for your time, literally!

Impressed, you even connected a ground wire!

Once everything is as close to working as you can get it, don't forgot to create a timelord@ email address for the relevent domains 🙂

Just tossed my first home made NTP based on a Garmin 18 puck and some really poorly soldered db9 and USB power leads. Was a fun project back then.

I see coax to a ham radio antenna in your future!

@strangenetwork

We all know where this is ending. Should we encourage Curous Marc to contact you or have you already reached out 😂

How timely of you.

Just turn the sand timer upside down, then twist the sundial on its mount.

When you figure out the secret to making more time, please do a video on that!

I can’t imagine it is a problem for a time lord 😂😂

Outatime? Just ask Christopher Lloyd. He has some experience with time...

@BoraHorzaGobuchul

I'd put the wires in a conduit - for the looks and so that strong winds don't whip it around

@sammosel3300

For best timing results you want to use satellites that are overhead or at least high in the sky. You might want to investigate specific antenna types, like the "choke ring" that give optimal performance for timing applications.

Nice to see some slack left as a drip loop 🙂 Watching with interest but zero plans to implement a GPS time base here TBH

(And no, I haven't yet secured the cable to the wall outside, forgot to bring my hammer drill today...)
