Custom Multi-Timezone World Clock with ESP32 and 6 TFT Displays in a CNC Aluminum Case

I built this custom 6-screen world clock powered by an ESP32.
Each 3.2” TFT display shows a different city’s local time, all synced via NTP.

The hardware part (soldering + wiring) took about 8 hours,
but writing and testing the firmware took much longer — around 1000 lines of custom code handling timezone logic, NTP sync, and display control.

It runs on a TRACO 12V→5V converter and sits in a CNC-cut aluminum enclosure I designed and assembled myself. It also includes a simple web interface for diagnostics and editing the city/timezone configuration
Works great so far!
