This should be in the request section, not contributions. This is specifically for layouts made by members of the forum. I saw that you posted this in the request section too. I can tell you that this probably won't get done on vero, as it lol be rather large. There is a pcb for the memory man made by madbeans, and I would go that route, IMHO.
Madbean will soon release a new board to build the DMM. If you really want a DMM I'd get the Madbean board for two reasons, A: its going to be complicated on PCB already, let alone on vero, and B: his layout is laid out for four MN3008 chips, which can still be reliably obtained at a reasonable price, versus the two MN3005, which have become unicorns made out of pure unobtainium.
Or..... just get the Dirtbaby. A PT2399 delay voiced to sound like a DMM.
