content: Hi all!,If someone in ANZ were to want to get started in electronics circuits and circuit design what is the correct standard for symbols for this region (or internationally). Reference web sites do not seem to adequately reflect what is current, or document what standards new standards replace. I'd rather not learn what is current sloppy US standard or 50 year old standards but best practice internationally or failing that best practice for ANZ. I want to know what is right, not to have history lesson.Does or should ANZ region be using the IEC60617 symbols or is AS1102 still current.An AU public facing uni course has these symbols shown.https://www.dlsweb.rmit.edu.au/toolbox/electrotech/toolbox1204/resources/04diagrams/03electrical/06symbols.htmWhat is best practice for ANZ beginners? Can someone help put history of former standards in perspective (or into the past).I'd really like in the least help for avoidance of old and US style symbols. Ideally I'd like to rely on knowing my eda packages can be adjusted to use this standard library (eagle, kicad, allium, gEDA)My guess as a beginner and quick googling is that some of the wikipedia entries are not very current, very US focused and don't emphasise what is current international best practice. With increased interest in electronics are beginners like myself learning bad practice from US based educational resources (arduino, adafruit, sparkfun).REFERENCE SITE EXAMINED.IEC 60617 (International)ANSI Y32 / IEEE 315 (US) – oldDIN 40900 (Germany) – oldAS 1102 (Australia) – oldRead morehttp://www.resistorguide.com/resistor-symbols/https://en.wikipedia.org/wiki/IEC_61346https://de.wikipedia.org/wiki/EN_81346https://en.wikipedia.org/wiki/Electronic_symbolhttps://en.wikipedia.org/wiki/Circuit_diagramhttp://trove.nla.gov.au/work/7568614?selectedversion=NBD13686692https://www.dlsweb.rmit.edu.au/toolbox/electrotech/toolbox1204/resources/04diagrams/03electrical/06symbols.htmhttp://www.freetronics.com.au/blogs/news/1658512-identifying-component-symbols#.WDDUM3emPwc{NLA}

content: Quoteelectronics circuits from Australia inparticularif you need the schematics publishing software used then contacthttp://www.siliconchip.com.au/or Leo ateditor@siliconchip.com.auSilicon Chip Publications of Australia.here is what electronics circuits from Australia look like. distinct from other non Australian schematics seen online. if you know your ozy schematics. you can pick it anywhere. note the wire jumpers and switch icons used in the Ozy art work.

content: What schematic software does the semicircular wire jumps like in the above schematics? I always thought zig-zag resistors was an American thing heh. Looks good though.

The example symbols looked hand drawn and they were trying to force the "new" ieee symbols down ones throatHere's an example of what an opamp should look like

content: Don't forget that in Australia (as with anywhere else in the southern hemisphere) we need to draw all schematics upside down, as schematic diagrams were invented in the northern hemisphere, and we are upside down compared to the northern hemisphere.Those EA and Silicon Chip schematics are great, but at some point somebody has flipped them around. Probably so an American can look at them. But if you draw them just as those linked images show, you'll be wrong.

content: Quote from: timb on November 21, 2016, 01:16:27 amIf you want to go back to the mid-20th century and draw schematics by hand get a template. Then your symbols will be nice and neat and uniform in size. Of course the only commercially available templates were made before all the new standards for symbols, so if you want to hand draw current symbols you will have to fire up your laser cutter and make your own templates.
