This is the first I'm hearing an aeropress 30 second plunge time, what's that about?

There are many different ways to use the Aeropress. I'd assume that the recipe the author is following simply asks for a 30 second steep time. I personally found that the time actually doesn't matter that much, you control extraction by grind size, water temperature and agitation. It might be that if you grind too fine you can still reduce extraction by cutting the time short, but that seems rather inconvenient for t…

The grind is the most important part I think. Super fine espresso grinds taste the best for me. Coarser, like french press grounds, need a longer agitation/agitation time but still have less taste.

Its just how long you are meant to let the coffee brew. Try if you make tea you need to let bag steep for a minute or 2. But actually timing it???? Useful if you are a goldfish may be but otherwise i dont understand who can’t remember to do something in 30 seconds. Fwiw i oftrn let me aeropress brew for a few minutes. 30 secs is hella short.

30 seconds works fine for other semi-pressurized brewing methods like turboshots or soup.

My trick is to re-use the filters. After the first few presses, the filters clog up somewhat and coffee doesn't drip through them as fast. So you can stir and let the mixture sit for a while, without resorting to maneuvers like the inverted method, which are unsafe for groggy programmers who haven't had any coffee yet that morning. But, I thought Arduino had become officially evil once it joined Qualcomm. Besides whi…

They have - but for less technical users their IDE is not too bad, and there are way too many bits out there relying on it, including lots of stuff not arduino, plus it's open source. And as it reloads files on changes can be used with a real editor as well. So for the software side I'm inclined to stick with that thing.

For hardware side it's different - but every interesting arduino has shitloads of clones available. In the past I've been buying those only for special use cases where there were no genuine arduinos to support the project - now since they got crazy it's only clones, and whenever I touch any of my old projects I'm updating the list of materials to recommend buying clones. You can still get nano clones for just a bit over 1 EUR each, so for projects where that is enough that's hard to beat value for the money.

Tbh the 30 second timer project probably could have been done with the legendary Padauk 3 cent mcu.

You can't use a 555, obviously.

You need to use two of them, or a 556, because you need one half for the 30 second monostable and the other half for the astable that drives the beeper.

Out of contrariness I'd use a CD4011 though.

You're right, but I think a 555 is maybe more than required for the buzzer.

Buzz-overkill, if you like.
