Glowing Air-Bubble Clock
via ShinodaY on instructables
“glowing air-bubble clock” displays the time and some graphics by illuminated air-bubbles in liquid. Unlike led matrix display, slooowly drifting, glowing air-bubbles give me something to relax.
In early 90’s, I imagined “bubble display”. Unfortunately, the idea was not realized at that time due to my limited skill and time, and similar idea products made by others until now. Now, the right time has come to me to realize my “glowing air-bubble clock”. Starting with some basic and preliminary tests, “glowing air-bubble clock” has displayed the time on my desk, at last.
