It seems bit odd to call it most accurate pendelum clock if the accuracy stems from being disciplined by atomic clock. To me the interesting question would be how far can you push the freestanding accuracy of a pendelum clock.
That is not to say this isn't a neat project in it's own right, it is, but just picking on the terminology.
- stavros 2y agoI agree, it's not a clock if it can't keep time on its own. It's a really cool project, but the clickbait title disappoints unnecessarily. "I made an NTP pendulum clock" would have been accurate and still extremely cool.

- technothrasher 2y agoPendulum clocks in general need to be periodically rated (length of pendulum adjusted) due to variations in temperature and pressure in order to achieve maximum isochronous movement. All this guy has done is created an automatic rating system. Otherwise, it operates the same way as most any other pendulum clock. So I think the "most accurate pendulum clock" description is fair (assuming it is the most accurate). I've had ideas for a while for similarly adjusting a pendulum clock from an NTP server, though I was going to add an extra gear to the motion train that would adjust the hands slightly every twelve hours. But that seems more like "cheating" that this rating system.
- KaiserPro 2y agoSo if you want the most accurate pendulum clock, then you'll need the vacuum flask one: https://www.rmg.co.uk/collections/objects/rmgc-object-79649 https://www.rmg.co.uk/collections/objects/rmgc-object-79649 or its german counterpart: https://theregulatorclockcompany.com/riefler/ https://theregulatorclockcompany.com/riefler/
