Glowing Air-Bubble Clock - ver.1 ; powered by ESP8266

The bubbles rising in the water form a variety of patterns and occasionally display the time. Air-Bubble Clock is also a kind of digital clock, so it may be better to have one that can be read accurately and quickly. However, I like the features that are different from electronic digital clocks, such as uncontrolled movement of bubbles. If you want to know the time right away, the small digital clock of the base box tells you. ESP8266 controls 8 solenoid valves to eject air bubbles into the pipes in the water. The bubbles, reflecting full-color LED light and shimmering, and rising with natural fluctuation, create a relaxing space. There are numbers that are good at displaying and numbers not good at. ;) updated version 2 is here: more updated version 3A is here:
