Okay Question for the Nerds

You have your phone and your wallwart to charge it, You've been abducted by aliens.

You want to charge your phone. The aliens have AC and DC but they don't use the same measure for voltage.

Assuming they can understand English, how do you explain what voltage you need to charge your phone?

(5v or 120v depending on how you want to play it)

Anyone know what this chip is? I can't find it online, and the JVC AV-20220 is a CRT TV. This is a chip in a Zenith VCR, and appears to be a JVC VC20220.

Edit: It's VS2022D, not 0. Still, can't find any data sheets.

Are there any XLR or ITT Cannon X-series connector fans out there who know where I can find replacement XLR contact pins such as these?
@askelectronics

They're from the base of a #Rode NTG-3 microphone, I'm missing one of the positive/neutral pins (top one in the image) but haven't had much luck in finding replacements. Contacted Rode but they haven't gotten back to me yet, figured if it's an easy item to source....

Ok, this part of the circuit seems incredibly cursed, and I am not sure I entirely understand how it works.

They seem to have combined the thermistor for ambient temperature measurement and a buzzer for making beep sounds into one pin on the uController, in an arrangement that is making my head hurt.

Any idea how this thing works?

EDIT:
I WAS WRONG!
There is a trace going to the centerpoint that I missed

#askFedi #askElectronics #electronics

Can anyone tell me what the reason for the cuts going into the traces where components connect is? (as in the ones in the bottom left side)
I cannot come up with any reason why they are necessary or what they do.
For context these are 220V AC inputs going into a AC to DC switch mode power supply (the little 8=pinner)

I can't find any information about the LCD (which is actually 6"!), however. It has a few identifiers printed on it (below). I know it's IPS and (purportedly) 1920x1080. It uses a 24-pin ribbon tape connector.

Anyone have ideas on what sort of controller board would be needed to drive this with (say) a Raspberry PI?

Identifiers/markings as shown on the back of the LCD:

• BL-B0500126AV0
• WH50296-00 23/05/08
• S2023040444
  • TS-B05000126A
• 230518 A B *

Any good ICs which can be used to create a keyboard interface? Existing options I'm working with are hard to come by.
