VFD-Tube Clock with ESP32 DevKit-C (170573-71)

VFD-Tube Clock with ESP32 DevKit-C with an accurate Internet-derived time


Clocks built using vintage components are currently very popular. Most designs are based on a real-time clock, synchronized via radio time servers or GPS.
The VFD clock described here uses an NTP server on the Internet to keep the time synchronized.

Details

Vintage components, up-to-date internet technology

The VFD-Tube clock (Vacuum Fluorescent Display) uses an NTP server on the Internet to keep the time synchronized. It is built around an ESP32-DevKitC module. This Arduino compatible board not only has a powerful processor but also has Wi-Fi and Bluetooth onboard. The Wi-Fi connection is used to synchronize the time.
When the clock is switched on, it connects to the network and synchronizes with the NTP server instantaneously. This is significantly better than synchronization via radio time servers or even via GPS.

Display board: date & temperature

Six widely available Russian IV-22 7-segment VFD Tubes make up the display of the date and time, in combination with two DM160 VFD indicators, flashing between the hours, minutes and seconds.

Arduino controlled

The program for the VFD-Tube clock was written using Arduino IDE v1.8.5. An Arduino core for the ESP32 software package available as an extension to the Arduino IDE.
Software and documentation available here.
