[sdiy] Pulsonix PCB design software

[charlie wallace]

because you still do the same verification but you also have other eyes on
ir.

for the srm32 i do a similar thing but i use the bsdls to generate the
layout i want to start with in eagle

with parts that are close then you have a base line to edit

on top of that stuff like snapeda and ultra librarian can be great and they
build  in to the tool
