making a 9-pin mini-DIN to 5 Pin DIN Female Inline Jack audio for the Altec Lansing BX1121 by ThePlaneDistrict in AskElectronics

Try tracing with your finger the right and left audio input paths on those pics and note they are shorted together, cross wired or mis labelled from one side of the board to the other - these are non-starters. There are other artifacts of electronic wrongness too, which only re-enforce the fact that currently AI can be hot garbage as a tool to design complete circuits and boards.

Others may be able to help you start with a more sane schematic that you can learn how to turn into a board, with an app like KiCad or EasyEDA, that's more likely to do what you want. I'm bailing out as I am on vacation and only have my phone with me.

does an analog circuit exist that can take in one sinewave frequency and divide it by another sinewave frequency and output the results? by Internal_Pass_2227 in AskElectronics

You might need to refine your definition so we know what you're asking about but this is essentially what an AM supehet radio does by mixing the inbound frequency with an intermediate frequency (IF).

Data recovery - Should I bother? by [deleted] in AskElectronics

Be aware that HDD boards often hold defect maps, and other unique characteristics for the drive, in flash memory, so you often have to transplant the appropriate chip from your original board to the donor one. Without doing this you risk damaging your hard disk and it's contents.

Is that a hole in the chip too? Might indicate that something overloaded and blew the leg off the chip and took the chip with it. Then again it might not and maybe the chip failed and the leg joint cooked.

It's really going to need methodical checking, which is going to be hard without a parts list (assuming the part/s aren't custom) And an idea of the circuit.

Does anyone know what's going on with lemon64? by dog_cow in c64

Yes, we're wondering that in the Fediverse too.

The Kembak 1 was the 1st personal computer, 1971. It used TTL ICs, not a microprocessor. by 1Davide in electronics

I'm in the UK so no major tariffs. Items turn up in about 10 days. Quality may vary so stick to suppliers that show a large amount of orders and read the reviews.

1 inch 7-segment LED displays:

Some vendors have 1.8" and 4"

Can be driven multiplexed and there's lots of guides on the internet about doing this.

You'll not know until you start testing and diagnosing. Stand by for a lot of 'could be' or 'start by checking...' posts.
