After a long time, I'm finally updating the prjoject.

Despite being on vacation, very small progress due to watching World Cup (another one just in 4 years).

I was stuck in the indecision between:

1 - Stick on breadboards, trying to find good ones;

2 - Use universal PCB boards, like these ones:

3 - Go right to the definitive PCBs.

This last one is my choice, and this is the first drawing in EasyEDA (unfinished):

Thanks for reading.

Same again, EasyEDA but I would suggest a mother board with small cards of no more than 10 chips. Ther reason it it is hard to debug a large board and it costs to redo a large board.

That would be my choice;  I'd rather route PCBs on the computer than solder the routes manually :P
