At the start of this project i decided to make the clock surface with different PCBs. PCBs in an arc shape, a PCB for a 8bit part, a pcb for the 12bit part and a control pcb.
Remark: i used 2 dual leds per second and the led's were place at the inside of the arc.
That looked like: see photo's.
But that was exspencive and mechanicly not so nice.
