I've been looking for a softer, less abrupt notification system than a vibration, sound, or light based notice. I couldn't find anything that fit that criteria so I decided to make my own. Furthermore, I wanted my solution to incorporate my personal interests in clocks and the way we as a society think about time.
From that, Blüp, was born. I came up with the idea of using a bubble in a container of liquid to not only notify me of an event of my choosing, but to also use the time it takes for the bubble to rise to instill a sense of urgency in my response to the event. For example, if you were to receive a message from a boss or other important contact, the bubble would form and rise at a rate that would give you enough time to respond before it pops at the top.
I’ll try to simplify the steps as much as possible so you can replicate this project at home, but there is definitely some experimentation involved in getting it to work for you.
