Building digital clocks is some sort of “Hello World!” project to most embedded hobbyists. And you can find tons of them with various displays and microcontrollers. But there is always a room for something different and unusual.
So if you have spare 130 LEDs you can do same easily. The guy, who calls himself Syst3mX in instructables, has built a digital clock by using discrete LEDs and Arduino. He made something similar to seven segment display where distinct LEDs are aligned and controlled like it. Of course lighting up such a bunch of diodes requires more power so each segment is driven by transistor. The overall effect looks really great
