One of the biggest hurdles for any DIY pcb projects is the complicated
learning and operating procedure of the CAD programs that are used to
draw the art with.
This is not so bad when the board is big and complicated which
justifies the time and effort in the design stage , but what about a
circuit of say , 5 to 20 components. ?
It is with small circuits that CAD become a big waste of time , you
spend more time on the computer than making the board and installing
the parts .... it's very annoying.
The other day (2006?) I had the necessity to build a small crystal
It is a simple circuit to make , especially as it has a low parts count
and no inductors to wind.
the artwork I decided to try a shortcut in the usually
complicated process with an alternative to the normal way I make the
board artwork -- it went like this.
grabbed some 5mm grid drawing paper and following the
schematic worked out where I wanted the copper tracks to be placed.
I drew it at
double size to make it easy as most components have leg
spacings in multiples of 2.54mm.
After I was
happy with what I had drawn I took a picture of it with my
digital camera can be used but it is better if it has a good
uploading it into my computer and downsizing it a little bit
to about the size that you see here , which makes it easier to work ,
I started to color in the shaded track areas with blocks of black.
These blocks are
made with the rectangle select tool that is found in
most simple ¨paint¨ type computer
Round pads can
be colored up by filling circles in a similar manner.
I didn't need to
do any freehand drawing , although that too is easy if required.
