I started this after being inspired by Neauoire's time formats and my experimenting with them in Ardusamber.

I wanted to design my own clock face that was ideally entirely visual.

I wanted something organic in contrast to Neauoire's very digital Neralie. Being mostly nocturnal during this time a thing that bothered me about Neralie was that the fidelity of readability decreased as time approached midnight.

This lead me to wanting Dastime being circular, spherical or somehow even through it's revolutions.

During this time I was listening through the whole backlog of the Philosophize This podcast and arrived at Episode 100 – Heidegger pt. 1 which talks about Phenomenology and Dasein...

Dasein "is a form of being that is aware of and must confront such issues as personhood, mortality and the dilemma or paradox of living in relationship with other humans while being ultimately alone with oneself."

"Dasein for Heidegger can be a way of being involved with and caring for the immediate world in which one lives, while always remaining aware of the contingent element of that involvement, of the priority of the world to the self, and of the evolving nature of the self itself."

"...turning away from the collective world of Them, to face Dasein, one's individuality, one's own limited life-span, one's own being."

Those explanations are difficult to parse but to me Dasein means having an understanding of the social, cultural and historic context, origin and byproducts of the things you live under, affect and drive you... then choosing which you want to allow to drive you toward your goals.

In this regard I wanted the clock face to reference to the origins of time, or rather how we beings from planets measure it - the rotation of our home planet producing periods of light and dark in direct view and shade of our home star.

The letters and numbers are there for debugging.

It is a top down view of Earth and the moon looking at the north pole, through to the south pole.

The triangle is your latitude which rotates mimicing Earth's rotation.

The white light on Earth shows the direction of the Sun which tells you roughly how far through the year you are (the Earth orbiting Sol). In the photo above it is 45% of the way through the year.

The position of the triangle as it rotates tells you the time of the day in reference to the direction of the sun light. Directly pointing toward the sun would be noon. In the photo it is nearly midnight.

The light on Earth fills to show the time of month. In the photo it is 53% the way through the month.

The other circle is the moon. The position of it as it orbits Earth tells you the current moon phase. The white light on the moon fills as it approaches the direction of the sun to reflect this (full white would be full moon).

I got this all displaying on Arduino but not animating.

I am happy with the time of day and lunation representations, but I think I can improve the day of month and month of year indications.

I'd consider adding an indication for the day of the week, moon types (blood, blue, super etc), seasons, solstice, and presession.

I would like to return to this project but will probably iterate the design with javascript before completing the Arduino version.

Still figuring things out...
