Relaxation Generator: Reloaded Internet Era Upgrade

摘要

I've now built three versions of this device over 10+ years, all of which worked well. Since I use it every night, it is one of my projects that, in addition to being interesting to build/program, I also use repeatedly. That's my justification for spending the additional time designing the newer models. I haven't mentioned that one of my original goals in building this newest version was to incorporate a GPS module. This module would: 1) Provide an accurate time (in place of the external, Web-based NTP server) 2) Provide a "local" NTP server that could be used by several other IoT devices I've built for my home, all of which have an ongoing need for the correct time/date. Currently they use the same "external" Web-based NTP server that this project does.
