Hobby Electronics Notebook

Pencil-style circuit symbols for planning a build the way you would on squared paper: wiring and power, resistors, capacitors and coils, diodes and transistors, switches, chips seen from above with their pin rows, logic gates, displays, sensors and meters, perfboard and connectors, and the marks written beside a circuit. Includes 80 flat drawings. Two-terminal symbols end at the middle of their left and right sides so connectors join them cleanly. They are informal sketches for notes and teaching, not a drafting standard.
