Local ESP32 NTP server with 10 time slaves

What time is it when you don’t have internet access? Find out how to control creative clocks using a local server and DIY electronics.

Smart Wi-Fi clocks synchronise their time via an internet connection. But what if you only have access to a secure Wi-Fi network, such as in hotels or public spaces? This setup demonstrates a simple solution: a local time server with its own Wi-Fi access point. Discover a range of DIY clocks, featuring 3D-printed casings and microcontrollers programmed using the Arduino IDE. A combination of electronics, programming and digital fabrication.
