The downside is that if you’re not an artist (or skilled drafting technician), your schematics will certainly reflect this, as mine do. This approach offers the ultimate flexibility – you can generally use anything at hand to draw your circuit, from your antique oak drafting table and Rapidograph pens to a stick in the sand. The field of electronics obviously pre-dates modern computer UI’s, so there is a rich history of hand-drawn schematics just open any book from before the integrated circuit era to see some. The simplest approach is just to take up pen and paper and get to it. Old-school: Drafting Pen-and-paper schematic So, readers of Hackaday, what do you use to convey your electronic design ideas to the world? Each one has its pros and cons, and may be better suited to one specific application, but you have to choose something. There are dozens of choices, from dedicated schematic drawing programs to using the schematic-capture facilities of simulation or PCB design tools, or even old-fashioned pencil-and-paper and its modern equivalents. So, given the importance of the schematic for design and communication, you’d think choosing a tool to draw them would be an easy task. And, if you’ve ever tried to explain a circuit without a schematic - in an on-line forum or over the phone, for instance - you know how difficult it is. Whether it’s literally on the back of an envelope or sketched in the condensation on the shower stall, actually drawing a design or idea makes a huge difference in being able to understand it. Unfortunately, even as my design experience has grown over the years, I haven’t quite learned to think in schematics - I need to see it on paper (or on a screen) to analyze a circuit. I can pick up a datasheet written in Chinese (a language I do not read or speak) and usually get a half-decent idea of what the part is all about from the drawings.
The lingua franca of electronic design is the schematic.
