Recycling of waste electronics - Digital tube clock

Let me start with the list (51 main components, minimum system) + 3 digital tubes (limited quantity) + pcf8563 (I have always used DS1302, but I was excited for a long time when I first got it, so I can try something new) + 74HC164 (to drive the digital tube with three transistors). Below is the picture

The 8563 clock chip is a ready-made one cut from the original board, with a backup battery. This lays a good foundation for energy saving. The battery was also found elsewhere. Unfortunately, there is no photoresistor. Because I originally intended to use it at night, I don't need to look at the phone to know what time it is. Now I can only add a button to start the operation. Turn it off during the day and turn it on at night...
