UNIX Epoch 7-segment led clock.

I am busy testing a modular 7-segment led clock. Each module can contain up to 3 pieces of 7-segment led displays driven by a 74HC595D shift register. Modules can be combined into larger strings.

7 segment led disply with 74hc595

In the video the modules are driven by an Arduino Nano 3.0 using the SPI interface. The Arduino is connected using USB to a computer which is running a C# program that instructs the Arduino to display a certain number at a specified position. In the video the UNIX time is displayed.

The goal is to connect the display modules to a server which is connected to the GPS atomic clock and display the exact time.
