Interesting, I don't think I ever saw it as anything other than some weird immortal aliens in non corporal form.
There's a lot of renewables in Europe, so some places it's reasonably sustainable.
Sweden has had a few hot days but not that many. It feels like we're plunging back into winter now, which is pretty much expected. I assume it'll be consistently below 18° by the end of the month.
Thursday it's supposed to be 27, then back to low twenties, high teens.
Nebula isn't really even in the same ballpark, super weird to include it there. Not sure when YouTubers started minting blu-rays and DVDs...
Ah, the Bejorans and their prophets, but that was more just wormhole aliens and not omnipotent gods.
Computer literacy is definitely down in gen z and alpha.
Did you watch beyond the first season?

Also by the bibles logic, if my dad was a murderer, me and any of my children are also murderers and should be punished.
As an ex AWS employee, you are so full of shit, it's leaking out of my screen. It also shows a low level of technical literacy imo.

Hi,
I'm looking for some help in a field that is super technical and I don't fully understand.
I'm planning on using a bunch of these seeed studio Esp modules for some home automation projects, especially because they have a lipo battery charger making it great for portable stuff.
The thing is the the ESP32s have U.FL SMD antenna connectors. Most of the antennas that you can buy with U.FL connections while are reasonably small, come with 50-150mm leads, which sort of makes the small size of the module a little less valid.
What I'd like to do is get a female U.FL SMD connector and make a small daugherboard with an 2.4GHz SMD antenna on it, for instance a Janson 2450AT42B100 or a Molex 479480001.
They go over the circuit board requirements quite thoroughly so I don't think designing it will be too difficult, but what I don't know is, they say that you need impedance matching on the circuit, and I see that there appears to be something that looks like it on the ESP circuit diagram, but I'm not actually sure if it is or not:
You can see it in the middle near the bottom of the diagram here: Seeeduino-XIAO-ESP32C3-SCH
So my questions are:
1: Is this a dumb idea, having a direct plug-on SMD antenna?
2: Is that an impedance matchning circuit between LNA_IN on the ESP chip and U.FL-R-SMT-1?
3: If I can't get a female U.FL SMD connector, would using one with a lead and shortening it to make the daughterboard able to be much closer to the connector affect anything? Do I need to ensure that the lead length matches the wavelength at all?
Edit: Found this SMD female U.FL, so they do exist.

Isn't that the entire point of his channel? To highlight obscure new tech and report on it? I don't feel like he's trying to punt anything, just maybe overly optimistic sometimes.
