DAB's Clocks is a collection of hand made, one of a kind devices that each display time in unconventional and interesting ways. For many of these clocks I have been fortunate to work collaboratively with several creative and skilled individuals. I'll typically build a mock up to confirm feasibility and essential design features and then create a simple rendering. These renderings become the basis for the fabrication.
Bubble Clock
The Bubble Wall Panel (20" x20", made of PVC and purchased at Amazon) has 26 bubbles behind which are placed LEDs. When the time is queried the hour (Blue) and minute RED) LEDs turn on simultaneously and then it's just a matter of counting the number of each. So at 12:55 there will be 12 Blue and 11 Red bubbles lit. Bubbles are lit in a pattern that appears to be random although blue and red bubbles will always be the same. Code could be used to create any kind of effect desired.
