Notes on Proper Schematic Capture

From MKRD.info Wiki

Let's look at a circuit which violates most good schematic capture principles:

Just about everything in this image is wrong. Let me provide a list which I do not claim to be complete:

  • Nodes are not connected with a dot
  • Symbols used are not standard. For example:
    • Battery symbol should not display the "-", as the symbol already specifies this.
    • Symbols used were pulled from different libraries, and this is why the MOSFET symbol is much larger than other symbols
    • Switch symbol is not standard.
    • The LED symbol shows what appears to be the standard high voltage warning (lightning bolt).


At least there is a circle around the MOSFET symbol. That's a welcome surprise.


If you need to draw a small schematic, do not waste your time and braincells on the idiotic available schematic capture programs -- just draw it by hand on a plot paper and scan it.
