Wise Clock 4 Dual screen chronometer
Update (June 30, 2014): This chronometer clock is complete now. It is also available in the two-sided (two-faced) version, aka "Kandinsky", as shown in these photos.
This chronometer, inspired by the Doomsday clock by Wyolum, is made with a Wise Clock 4 board (available for sale here) and two 3216 displays from Sure Electronics.
Its main feature is the odometer-style rolling of the digits when they change.
The time is updated once a second, based on the 1Hz interrupt signal from DS3231, as described here.
As shown in the video, one button is used to change the display brightness, another button is used for changing the font, and the third is used for switching between rolling style and static style.
By using the bigger (5mm) 3216 displays with the same setup and software, this clock can be easily read from a distance of at least 100 feet (30 meters).
Source code is available here. The current version does not allow setting up the time and date from buttons.
