Someone else made a comment in another thread here about weird
schematics (like for home appliances).

Wanted to get a small discussion going on that topic. My take: there
are
good and bad standards for schematics. Personally, I can't stand the
ones that use rectangle shapes for resistors, instead of the
traditional

I find rectangles obnoxious, unless somebody from europe is drawing
something in front of me.

zigzag that [insert name of deity here] intended to be used. (And even
here there are lots of variations, like old-fashioned schematics that
took this symbol rather literally and sometimes had ten or twelve zigs
and zags, as if an actual resistor was being constructed on paper).

Likewise the 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 was taught the half-loop shape first, then moved to the dots and no
dots. It seemed like how you're taught to ties shoes in a really complex
method of making two rabbit ears first, then tying them.

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 that on this newsgroup. My question is what idiots came up
with it and why?

Can you really not understand it ? Or are you being deliberately obtuse ?
It
has now been explained to the point where a child could understand it. I
think it was actually me who you first saw using it here, and I'm pretty
sure that we went through it all for your benefit at the time ...

That's funny as writing out values the correct and conventional way
doesn't need explanation and a child can follow it, and it's been that way
for decades.

I'm still waiting to see values for money being written out as 44"euro
symbol"66 with cents after the end instead of 44.66.

periods are too confusing, commas are too confusing! help, we're all
stupid these days!


OK then. You started going on about writing voltages in that notation, as
though you couldn't understand that either. Do they not sell zener diodes in
America ? That notation has been used for as long as they've been around.
Like BZY88 C6V8. Have you never seen that, or perhaps you've never
understood what it meant ?
