I've done some reprehensible things, but I don't think I'm a bad person. Bit of a short temper but I try be good to everyone and not hurt or use people like I was. But if karma existed, you would say I was a veritable Genghis Khan

They pioneered modern day planned obsolescence, they also popularised unrepairable electronics. They try to block or bastardise any right to repair bills. They force chip distributors to not sell chips they use so their products can't be repaired. They make building applications for Mac at scale a huge pain in the ass and extremely expensive, the solution I recently built wastes insane amounts of power because of the way Apple licenses their stuff. Overall it's a shitty company who fucks poor people in developing nations, fucks the environment and fucks it's customers. I don't care how well it may or may not work, fuck Apple.

Also OSX ui is shit and annoying.

Same here. I'll pirate the security updates for the next 3 years and then switch. Fuck Windows 11 and fuck Microsoft.

Not sure where you're getting that from but okay. I'm not going to argue with you. I also didn't know that stating that a political party is shit was xenophobic, I'll keep that in mind for the future. I hope you have a great day.

Careful, the mods consider what I said radical and breaking lemmy rules (gestures vaguely). Apparently independent operating systems are a taboo here.

Pretty sure the studio I work at will have layoffs by the end of the year. Fuck Microsoft.

I guess you're right... Need a Linux distros like that so that can also change.

IPad? From an even worse company? Linux all the way.

Pro and Ent are way easier to "spoof"

Yeeeeah, no enterprise admin would run that.. GPOs would do the same with more transparency and no privacy concerns (besides running Windows of course)

I fucking hate that it feels like JC "stole" the songs identity from NIN. IMO it sounds awful, there's so much more raw emotion in Trents voice. Ugh, give credit to the man who actually wrote it.

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.
