Design submitted by Sam from Germany.
Sam says: The inspiration for this watch is a particle collider. The basic idea is to have two different types of particles coming from the straps and colliding in the case and explode in a pattern that tells the time.
This pattern is based on an analog watch display and uses LEDs. The red ones tell the hours. On an analog watch the hour hand is shorter, so the important LED here is close to the center. An additional red LED which is further away from the center means it is PM. So all red LEDs belong to the hours. All blue ones belong to the minutes. On an analog watch the minute hand is longer, so the first LED to check for the minutes is further away from the center. This LED tells the minute in five minute increments. There are up to four additional blue LEDs closer to the center that have to be counted and added to the first minute value. That’s how the time telling works. The scatter pattern looks confusing at first, so keep the length of the hour hands in mind for the main LEDs and then look at the remaining ones. There is a white LED in the center, that flashes when both particles collide.
The blue and red LEDs will never overlap so there won’t be a magenta light. That would have added more diversion but would have been harder to decrypt. The main LEDs (hours, five minute increments) run on separate circles, as well as the secondary LEDs. The secondary LEDs are always placed on the opposite position of the main LED on the same circle. The most difficult part is making each LED position capable of showing both colors, but that has already be done (see the epic Adjust watch!).
There have to be two buttons pressed to emit the particles. I like this because it reminds me of those two keys that have to be turned simultaneously when things get serious. There is this edge running around the watch, always reminding the wearer of the particle trajectories and just making the watch look cool when being of. The center LED has to be as bright as possible to give a nice wow effect of the collision.
So that is the Collider LED watch concept.
