Well, regarding the recent developments, I doubt anyone will go for avalon chips now that Bitfury is here and 2nd gen is a few months till shiping.
But this is a hobby project which I intend on finishing, if ever get my 48 chips.
Anyway, I finished the ASIC board. The schematic pdf, GERBERS and eagle files are on this github.

Now I'm going to start on the other PCBs.
