I feel like I should leave the gaming industry

You're probably better off
But you're not discussing it, your projecting your world views on others and making accusations and assumptions about me. Which I don't really appreciate. You neither know me, how my mind works or what I've gone through. It also seems like you may or may not understand how mental health issues can affect cognition or perception.
So with that, I'll end the conversation there.
It was a joke. Just like "If a tree falls in the forest, and you're watching a video of it on Linux, does it make a sound?"
I dislike Bluetooth anyway, it's a shit protocol.
Uh, I've never used inches, nor know anyone who does - a South African
What does that even matter?
Maybe I don't want to be alive? Maybe being alive was something that was done to me? Maybe being born into the family and body I have is the trick?
Like, you sound so pedantic, bitter and quite angry about something people say to express something happening slowly without necessarily noticing how bad it is until something brings it to their attention.
Believe it or not, and this may be hard to grasp, but not everyone experiences life the way you do in your head.
Most likely, but the acid I think has the strongest scent.
I do.
I wasn't, I was just responding to the previous person as to why it's annoying
I'm on a instance that doesn't allow down votes
Ant go squishy, formic acid go splat?

Some advice on creating a 2.4 GHz antenna for Seeed ESP32-C3
(lemmy.blahaj.zone)
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.

Probably just designed to fail maybe?
