Fuck that, who gives anyone the right to force me to be alive? Fuck anyone who believes they get to have a say on if I choose to continue or not. You are just as bad as the pro lifers

Lol, the alternative is being Leyak lunch.

Oh shit, you're right, sorry, I corrected my comment.

Is this the motherfucker you have to stare at?

Lol, I hate people licking corpo boots. No company deserves my loyalty. That's been proven to me over and over again, they also definitely don't deserve my best either. They can get what they always give, the bare minimum to stay an employee.

I guess they're just going to end up being really good but heavily overpriced like the rest of the FormLabs products.

So I've worked in IT for around 18 years now and in that time I've worked for 2 gaming companies, I started my most recent a year ago, but I'm wondering if I should just jump ship for the tech industry again, I'm now waiting for the layoffs in our business unit. I'm an immigrant living on a work permit and losing my job will mean losing the life I've made for myself over the last 4 years, and that terrifies me.

I used to love the company I work for but now I'm wondering if it's worth it anymore.

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.
