The pictures look beautiful. Can you answer a few questions?:

- Is that "double sided copper clad laminate PCB circuit board" like
  available all over Amazon?

- What method/tool do you use to scratch/cut-out the divides in between
  the islands?

- on the raised islands, is that just another layer of copper clad
  laminate? Is there some special material I'm seeing underneath the
  blue break-out boards? What tool do you use to cut out chunks of the
  laminate?
