Some people like to know exact time (hours, minutes and event seconds) while other are satisfied with “around” time. So this project might be just right. It is fairly easy to build since there are only twelve single color LEDs used. NextLab did their job to the end – instead of leaving circuit open, they laser cut nice acrylic enclosure that makes this clock stand out.
Clock is powered by Arduino Nano. Even if displayed time accuracy is half an hour, internal time is kept precisely with external RTC DS1307 chip. The motivation of this is that platform can be used for future projects where someone might want to build accurate display like using RGB LEDs or different methods.
