Homebrew PCBs

I'm looking forward to it!

But please, post it in Files, not Photos. The Photos section only
allows everyone to see a 300x400 max size, only the moderators and the
uploader can see the original higher res images.

There are no such limits in the Files section.

do it right or resolution goes to pot.  When I get it done - a week or
two from now - I'll post it to the photo section of this group as well.
