ESP32-based Alarm Clock connects to Timeserver and controls Radio & TV

Cloc is an easy to build alarm clock without SMT parts. It has a double 7-segment retro display with variable brightness. One display shows the current time, the other the alarm time. Cloc connects to a Wi-Fi network, so it can access a timeserver somewhere on the planet. It can connect using DHCP or with a fixed IP address. An optional DS3231-based battery-backed real-time clock (RTC) module (not included in the kit) can be added to keep time in case of network problems.

The built-in web server shows the time, allows setting the alarms and lets you adjust the clock’s parameters. The optimized graphical HTML interface works on most standard browsers and handheld devices.
