This is neat. I'd love an NTP sync'd wall clock but my time for hardware hacking is pretty limited. Are there any off the shelf wall clocks that do NTP? Bonus

- orev 6y agoIn the US you can get clocks that auto-set by tuning into the NIST radio signal WWVB. They come in both digital and analog, with various designs. They don’t need Internet; just some regular batteries.

- samm_cz 6y agoIn EU using DCF-77 probably would be more practical. I am sure that similar radio-s are in US too.
- m-p-3 6y agoOn my end I wish I had the knowledge to make a similar clock but synced to GPS time, allowing to set the timezone and DST using DIP switches on the back. It could work anywhere a GPS signal can be locked, no need for an Internet connection.
