Inside the boxy blue base is an Arduino Nano, a DS3231 real-time clock module, and a perfboard full of transistors for switching the LED strips inside the segments.

The clock is powered by an Arduino Mega and it uses a DS3231 RTC to keep the time. Each digit has two sliding grids which are affected by small stepper motors.
