I say this as someone who shares this mindset. It is as shocking to me that you would queue up for a dangerous vaccine, support mass 3rd world immigration, consume slop full of soy and seed oils, etc as it no doubt is to you that I would be an openly racist anti-vaxer who gets his steaks and eggs straight from the farm (and would my milk too, if it wasn't illegal here).

It doesn't help at all that the champion of pasteurization was one Lord Rothschild, whose only two addresses to UK parliament were for Zionism and the prohibition of raw milk. If one is considered a program of genocidal supremacist hatred of my people, it's a very tough sell that the other is supposed to help keep me safe and healthy.

The princess doesn't want a gem on her finger that has been cultivated by a nerd and comes with a "vegan, soy-based, cruelty free" approval on it. She wants a warlord to return from conquering and pillaging foreign lands, leaving rivers of blood in his wake, to deliver the prize to his queen as a symbol of her value and his material investment and dedication to her.

Obviously no woman in her right mind is consciously thinking that, but that's the psychology behind it. "Bloodless" is icky.

The hobbyist solution would be to find some obscure product on AliExpress with a holder for 2xAAAs and a 5V boost regulator with a USB connector. It's janky and inefficient, but that'll power your board, or your iPhone.

The 'proper' solution would be to then take this prototype to an optimised design in your ECAD software of choice, integrating a AAA holder and choosing an appropriate regulator, and having some PCBs assembled.

I'm not sure what else you could want. If the latter sounds daunting to you, it would be very easy for even an inexperienced EE on Fiverr to whip up for you.

If you're designing your own board, you would simply enter 3.3v and >150mA into the parametric search on Mouser, Digi-Key, TI, etc and pick whatever part takes your fancy.

This is so simple that there isn't any need for a guide. The datasheet for whatever regulator you choose will tell you the recommended input capacitance, output capacitance, inductance, any configuration resistors, etc.

Same goes for battery charger ICs, which can be just as simple or far more advanced, and there are new devices being announced all the time for everything from tiny energy harvesting applications to USB PD, which is what I mean when I say it'll be obsolete by the time it's announced.

It's daunting at first but you need to take the plunge: find a part that interests you on Mouser, integrate it into a design according to its datasheet, and order some PCBs. You'll be amazed how accessible it is.

There are so many factors that it's a near-impossible task. And even if you somehow managed to do so, it would already be obsolete by the time you stopped typing.

The datasheet (for each of the ESPxx, regulator, etc) will specify power consumption in different states. But sadly there's a lot of misleading amateurish pseudoscience in Arduino-land so you're best to ignore everything else (which would even include a guide like this, for example).

Tell us what you really think, loxist

That's nice and all, but 15 minutes is a much lesser achievement than the headline implies.

>...would not have survived the winter.

Taking Europe, for example, our ancestors would not have survived without their adaptation to the climate and its consequences, breeding cooperation, empathy, industry, invention, efficiency, etc. A frivolous, impulsive, unintelligent people seeking immediate gratification would not have survived the winter.

Do you actually? That's appalling.

Some time ago I was on a second date with someone (met through a friend, not Tinder) whose phone was frequently pinging the Tinder notification sound. She was very pretty, I was under no illusions about the level of competition, but I was so insulted by the disrespect. Imagine not even putting your phone on silent! Had no idea it could've been worse, god help me if she got it out and started swiping.

Well, no shit.
