I have these. Do you have more?

The above have been working for me quite well. Take care. -- _______________________________________________________________________________ "The Force will be with you, always."

I like: _|_ for normal diode, _|_for zener diode _|_ for SCR /_\ /_\` ->/_\ | | | For transistors, FET's and valves (aka tubes) I like the same approach used for integrated circuits, e.g. | |+9v (usually omit power supply in diagrams) [c] [j q] |\| --[b]2N3055 [k -q] --|+\---- output [e] ---|-/ 741 | |/|____-9v i.e. a "box" with the elements labelled (c,b,e or s,g,d, k,g1,g2,a, j,k,q,-q, etc), and a label outside the box saying the type of device (2N3055, OC71, BA102, 6V6GT, 74LS74, or simply NPN, etc). Using the capital letter of Pnp, etc isn't a bad idea, but the name of the connection is easier to read (and harder to confuse). > Resistor -R- > | > R > | > Capacitor ("C" being +) -Cap- > | > C > a > p > | > Ceramic Cap (nonpolar) -||- > | > - > - > | > Not bad, but how about e.g. -47R- to indicate a 47 ohm resistor, -220KR- for 220Kilohms, -100nF- for 100nF capacitor, -10uF+-- for a 10microFarad electrolytic, with + end marked. -R- (or -^v^v- or | > < > | if you have enough room) and -C- or -||- or _|_ ___ | again, if there's room) are okay if you simply want to show a general capacitor, without giving its value. I'd prefer the same symbol for nonpolar and polar capacitors, but with a "+" added where appropriate. I'd like to see a good standard for ASCII circuit diagrams, and preferably one where the circuit looks okay "as is", *and* can be automatically translated into proper HPGL or postscript or whatever. Using characters like "/" and ">" as I have above is not as good as, for example, -220KR- for automatic conversion, and in my playing with the idea so far, horizontal components are significantly easier to recognise than vertical ones. Anyone else doing this sort of stuff?? Mark Aitchison, University of Canterbury.
