This DIY clock takes after grandma’s in a number of ways. For example, assuming you follow the instructions to the T, the case should be printed using wood and copper PLA. Apart from that, all of the inner workings are just like those found in grandma’s clock.
The software is special: the clock corrects itself via software and an Internet connection to a NTP clock server!
At regular intervals, the software will poll the NTP clock server, and the time received – from the NTP server – is recorded in the ESP32 clock. Whenever it’s 12:00 (either noon or midnight) and the clock happens to be off for any reason, the software will fast-forward the hands to the 12 o’clock position, from which point the clock will resume its operation.
