I have not designed a PCB board, but I have drawn serket diagrams with the
Sensational Blackboard:
Email me and I can get you on a beta for an app to digitally    label the
For viewing existing diagrams, we still need a transcriber sadly. Swell
paper may help, or a View Pluss embosser.
If you can get your hands on a Graphiti, it may help, but DPI is like 6
whereas an embosser is around 20.

Open SCAD is the best 3D modeling tool at the moment:

I personally love the Grove Arduino Shield:
It's so easy to build items with the Grove shield, it's legos. In my
masters program, I was switching prototypes in class because rewiring is so
easy and quick.
I never needed to trace out my cerkets though.
