Some segments start to work :-)

The light looks nice :-) It will be better on a black background.

Many segments are still missing but we can at least test the resistor networks. Half of the segments are required to test the circuit with one 74HC595.

And the signal generator is taking shape, it can generate a 5Hz signal or single pulses to help test the boards.

I had to revise the resistor values because the original, theoretical values were wrong...

Still missing: another debouncer for the data signal.
