ESP8266-imitation digital tube clock

Overview

Project modified from: https://oshwhub.com/wangsheng0520/led-shi-zhong

The code has minor modifications and non-existent modules are commented out.

The project is imported from kicad professional version and has not been strictly checked. It is recommended to use the provided gerber file.

The PCB is a puzzle and needs to be cut by yourself. The RTC battery uses CR1220 model 3V.

The drawing board of Yeluzi is horizontal, do not spray.

The hood is printed with black filament or sprayed black after printing to reduce halo.

The front panel is welded with copper flower nuts and fixed with base plate screws.
The base can be welded with copper pillars and copper flower nuts as support, or the shell can be designed by yourself.

The actual halo is not obvious and the numbers are clearly visible.
