| are drawing normal schematics a dying art? |

As I said already, do you want to just replicate projects someone else designed? Then pictorial away. Do you want to actually learn how things work so you can start modifying designs, and designing your own? A clear schematic is a wonderful tool. I did a class in reading and drawing schematics for some local makerspaces. All of my examples of how not to do it came from Make: Magazine. Older datasheets are great! They designed new ICs and they are trying to get people to use them. So they put a lot of effort into including reference designs and examples, with special emphasis on clarity. I'm not telling anyone else what to do, just expressing my opinions. |

I found it fascinating, and began modifying, and understanding at a primitive level, those designs. Eventually it turned into my passion, which led to a great career. Now that I'm retired, it's still a passion, and my main hobby. I don't know where I would have ended up had I not started out copying other peoples work. Probably as an old guy playing bass in a bar-band for tips (one of my other hobbies, except for the tips). |

If you want to build a circuit you SHOULD take the time and effort to sit down and work out how it functions and what the components are doing. If you're blindly following a guide, slotting modules together or doing the electrical equivalent of "dot to dot" kids books, then don't you DARE go and show off your copied device to someone, boasting and accepting praise. People ARE VERY lazy nowadays - they want the rewards and adulation without the hard work (look at society too - Instagram nonsense etc - everyone's constantly out having a huge "party", and yet they've got nothing of any substance to be celebrating, if ANYTHING - it's an attention seeking generation) |

That is very myopic. People learn differently and get their motivation in many different ways. The process is a continuum of successes and failures and the learning comes along the way, not a pre-requisite. For a kid like me starting to get the taste for electronics at the early age of 7 or 8, a successful build was incredibly rewarding and a feat on itself, which led to more builds and deeper understanding. Without the "blind copy" there was always a chance my interests would go elsewhere - at the time I was also interested in mechanics, but the lack of hobby magazines and the difficulty in assembling things without standard and mass produced parts available on a store were a huge stumbling block. I am not the only one. Many of my youger co-workers started copying and assembling circuits and code using Arduino and simpler stuff and are starting to make a career out of it. |

Not like the army of new generation dummies who drops parts on the schematic sheet and terminates every single pin with ports. --- End quote --- This. Also, modern board designs are 5 ICs, 100 decoupling capacitors, 500 nets, and 3 resistors. So much of circuit design has moved into IC design that I know people who just say "I'm a circuit designer" to mean "analog IC designer." It's pretty understandable that few board level schematics look like the beautiful drawings in the end of an old HP service manual. Finally, I have to say looking at some fritzing schematics to see what it was all about that I am a bit disappointed that regular schematic design has not adopted color. Many schematics will only ever be viewed on a monitor and color printers are hardly more expensive than black and white. Color coded nets definitely could certainly be abused but it could also be a powerful tool for communication of intent if done properly. --- End quote --- Back in the 1960s, Schematics with different colours were used by some manufacturers, but personally, I found them hard to read. They disappeared after a while, so I mustn't have been the only one of that opinion. |
