You're mixing disciplines. Separation of concerns is a computer science principle. It very much doesn't happen much when one is designing analog electronics, which is where fuses come up. If I'm designing a piece of medical e

FYI: Page 6 is worth looking at. * A 25A fuse will conduct 52A-110A for 5-10 seconds, which is about the 2x in my original post. * For shorter time periods, this goes up a lot (150-260A for 100 milliseconds). I'm getting down-voted, bu

Proper brands are not "Nilight" but companies like Vishay, Littelfuse, Eaton, Bel, Bourns, and similar. Those brands can be found on sites engineers shop on, like Digikey, Mouser, Newark, and similar (which also lets you price &#x

Is English your native language? You might be confusing fuses with breakers. Fuses aren't typically used to protect copper runs; breakers are. Fuses are used inside of electronics. Breakers are rated as you describe, to protect copper

When I was a student, my lab professors had a saying: "Sometimes a fuse will blow to protect the circuit, and sometimes the circuit will blow to protect the fuse." One problem is that fuses are thermal devices. They break due to o

My suggestion would be to travel the world, and see how people live in places with different margins. Life is sort of okay. Look at Soviet-era Eastern Europe, India, the diverse approaches across Africa, China, the rest of Asia, etc. People

For the record: Some of these are a bit over-the-top, and Amazon is trash for anything safety-related, but for the record, virtually all fuses have a pretty significant margin before they blow. The risk here is very limited: - A 2A fuse nee

Pro-tip: I work very hard to help make generic the trademarks of corporations I think are evil (and vice-versa for ones I like). It's a free, cheap, and easy way to fight back. To the great annoyance of many, I even usually google for

I enjoyed reading this. I'm not criticizing, but having used emacs for more than a quarter-century now, I keep things a lot more vanilla. My .emacs file is 63 lines right now. If you have emacs with vim keybindings, a purple flying toa

> It's just super ironic the parent post said they avoid counterfeits and knock-offs by shopping on Aliexpress. Aliexpress is basically counterfeit and knock-off central... It doesn't. You read it wrong. Read it again.

Can you name any specific instance where people were harmed by toxins in clothing? The skin tends to be a pretty good barrier. Creams and cosmetics are often designed to penetrate it, but clothing fits within my risk profile. I come in cont

I don't wonder. Fakes and knock-offs were rampant on Amazon -- for a long time, more common than genuine product. People tested them. That's especially true for brand names like 3M. I only bought through trusted supply chains. My

I agree with the math, but not the spirit. 0*100 = 0. Aliexpress is fast, efficient, but completely random and automated in resolution. Products from Aliexpress are great 50% of the time, non-working or not shipped 10% of the time, and some

I think you misread my comment. I'll go to Aliexpress and eBay first for: "kids toys, cables, generic keyboards, battery chargers, basic tools, and basic clothing." I have the exact same list for them as for Amazon. I'll

It's not quite the hill to die on. There are (at least) two definitions of "theft" and "stealing" in common use: 1) I take something away from you. You have less of it as a result. Copying is not theft. 2) I deprive

My experience is that 90% of the work on these projects is integration: getting the toolchain working, and all the pieces talking. If there were an easy-to-use digitizer and a documented toolchain, I'd buy a LilyGo T5 right now. Withou

It depends on how it's implemented. Take a look at: https://www.home-assistant.io/ They have customizable dashboards. What I'm really looking for is something I can use as a sort of command center in a few places
