A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.
Rules
- Don't throw mud. Behave like an intellectual and remember the human.
- Keep it rooted (on topic).
- No spam.
- Infographics welcome, get schooled.
This is a science community. We use the Dawkins definition of meme.

Electronics engineering is a bit beyond my scope; as an electronics hobbyist or field repairman you're gonna get the closest I have in my kit at the time, I'll probably get within an order of magnitude of the spec unless it's somehow very damn critical or the schematic calls for one of the oddly common oddly specific values like 220 ohm.
Well, just think "How would I do this cheaply and get away with it" for a good enough "Engineering" approach for this case.
The really expert "Engineering" stuff related to things like maintenability, reliability, robustness and so on (which I myself am not qualified to talk about, as even though I have an EE degree, that's not actually the domain of Engineering I ended up working in so I haven't accumulated the professional experience that teaches one to take such higher level considerations into one's designs), isn't, IMHO, really necessary to understand to explain why those designing circuits commercially would chose the commonly available and cheaper components if they can.
