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

There are minor changes to the code that comment out modules that don't exist

The project is Kicad import professional version, which is not strictly checked, and it is recommended to use the provided gerber file.

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

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

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

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