Nice try, but no.
Nothing in an electronic device, save for a very overvolted capacitor, could come anywhere near to as explosive as these were. Even LiPo batteries don't explode like that.
These were explosives planted in the devices when being manufactured.
Not sure if you've seen videos of the explosions or the aftermath.
I told my manager that I've been burned and can't make myself work hard for another company again. She's leaving so there's no vested interest in the company for her. But yeah, fuck these cunts.
Are you also finding copilot to be less helpful of late? The other day it couldn't follow the simplest of instructions
The Win10 one can be pretty handy if set up nicely.
Yeah, AliExpress is the baby version of the wholesale platform Alibaba, and they're now a big enough company to also have their own cloud provider. Temu, Wish and Shein are all trash.
Yeah, nah, I'm not gonna pay 10x the price for a knockoff arduino from a local seller that just buys it from AliExpress anyway. There's no better place to get electronic components and modules without bankrupting yourself
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.

People trying to argue with this point, but the point is that if the punishment for a crime is fine, then the crime only punishes the poor.
