In all seriousness, the absolute crap that manifests from schematics developed in Eagle coming out of the open source community is a personal pet peeve. An example of almost everything you shouldn't be doing with respect to at least the following can be found here: color, symbology, scale, reference designators, typeface, labeling, orientation, functional grouping, density, overlap, flow, etc. It's a shame there's zero reference to industry standards like IEEE Std 315 and ASME Y14.44.
Abuse of color is probably the one thing that really drives me nuts. I'm of the opinion that if electrical intent cannot be cleanly and unambiguously conveyed in black and white, it's garbage.
I secretly wish EEs in general exercised the same level of meticulous attention to detail and pride that designers in the typeface community do, in the same vein as this comment[1].

- ultrarunner 8y agoHaven't ever popped open anything that came in an Amazon box? At least with OSHW you can submit corrections to bring into compliance with any standard you find relevant. Better than firing off a sternly written letter to China (or HN).
- metaphor 8y agoThe OSHW community has every right to distribute crap schematics, but it isn't immune to criticism. For the record, I haven't opened an Amazon box of my own purchase since 2016 (dropped that like a bad habit after 10 years of Prime patronage), although I'm admittedly failing to see what the relevance of Amazon and China have to do with this discussion. I don't contribute to the OSHW movement because, quite frankly, if I can't buy the custom hardware solution I need, I'll design it myself.
- Taniwha 8y agoyou can print out your eagle schematics in B/W if you like, it's not hard - just click the "monochrome" box in the print dialog
- zrobotics 8y agoI think the problem here is using solely color to distinguish connections. Ive definitely seen schematics where, if printed in B/W, are impossible to read.
- metaphor 8y agoYes, that's effectively what I meant when saying: > ...if electrical intent cannot be cleanly and unambiguously conveyed in black and white, it's garbage. The problem isn't just constained to connections though: consider adjacent symbols, components symbol elements vs. nets, nets vs. busses, components in which physical color is a salient characteristic, etc.
- l0b0 8y agoDo you have a good example of schematics? There's nothing quite like real-life good design (think Tufte), and far too much space is given to how things are done wrong as opposed to how it has been done right.
