A cool new device landed in our post box this morning: The "Azevedo nwts".
This little gadget is an interface between Internet atomic clock time sources (using the NTP protocol) and clocks which have a GPS input.
GPS is a stable, accurate time source, but was really designed for "clear sky" use, meaning that it works best outside of your home. Where I live, I have trouble getting a reliable GPS signal when I move a clock away from the window. The "Azevedo nwts" solves this problem, by providing a GPS compatible signal, but getting the time from your WiFi network instead of a GPS satellite. The "Azevedo nwts" works with any device which uses a GPS signal, but has so far been tested with:
- PV Electronics Spectrum IN-18
- PV Electronics Frank 3 IN-12 IN-17
- PV Electronics Halo ZM560M
- Mr Nixie clocks
We will be doing build review of the pre-production device that we have, and a full review as soon as production starts. Watch this space!
