My vision is impaired.

I have something like macular degeneration messed up retinas and
everything looks crushed and twisted to me so

I need bigger, much bigger , everything .......when I tinker with
electronics.

and

all of the CAD interfaces have tiny text on racks of tools and buttons
onscreen

and

all of the features and settings are easily trashed by me tripping
accidentally over them

so

I step back and declare thats not my tool set and stick "caveman" simple
... paint on the wall.....

and get the desired results.

and

I share these tidbits with you all because HOME BREW PCBS is really at
all levels.....?? from the simple hand drawn sharpie on PCB to the
advanced CAD

programs with detailed granularity tracking component libraries.


There is something for everybody here.

I learned how to make GERBER files last winter.

Neat stuff.

Have fun.

I am.
