"Hydraulic Schematics and Basic Circuit Design" provides an overview of basic hydraulic circuit configurations and the standard fluid symbols in fluid schematic diagrams. A hydraulic schematic diagram ...

it’s great for a quick-and-dirty circuit diagrams. Not exactly schematics, but [Duckman] has some Arduino pinout diagrams he made using ASCII-art. These could be useful when pasted into source ...

We can see how circuits work, and represent them with some simple diagrams, using basic electrical components like these. You start with a cell, or combination of cells. These could be batteries ...

Improvements to the KiCad Schematic Editor include smart wire dragging that simplifies moving components around within schematic diagrams ... are also additions to circuit simulation and modeling ...
