... wire-connecting/jumping convention: here I much prefer the
modern approach, which is to use a dot for a connection and no dot for
no connection, rather than the clumsy "loop" to indicate one wire
jumping over another with no connection.

I find the 'gap' convention is easy to draw (with a computer) and
extremely easy to read. It also looks tidy. Four-way junctions which
could be mistaken for crossings should never be used, they should be
staggered instead.

Regarding resistor values: Who the hell came up with that new way of
specifying resistance values, like "10R" "or 5K6" or whatever? And why
use this system? I've always used the plain value of the resistance: 10,
56, 5.6K, 56K, etc. Simple, obvious, requires no interpretation. Is this
some kind of Euro thing?

I first saw it in German and Dutch publications. Once you have become
accustomed to it, it is quite easy to use and it is utterly unambiguous,
even when badly photocopied.


Probably the best circuit diagrams were those in Wireless World when it
was still part of Illiffe Publications (also those in BBC Technical
Instructions). They were drawn by trained draughtsmen who also
understood electronics.

The worst ones are those with boxes. A symbol should indicate what the
component is without having to read the small print. I was very pleased
when Wireless World declared that it would not be following British
Standards and would continue to use 'proper' symbvols.
