I saw it is basically superseeded by the vc-5080 and vc-5081, but I am not finding any good comparisons and don't know enough about this to understand the difference myself.

My usecases are basically checking whether my soldering is connected, whether some switch is working, whether a cable is broken (thus why I am looking for a analog ones: easier to see the needle changing) and sometimes some simple voltage and resistance checking. So as far as I can guess I can I don't need the precision which I would lack with a analog multimeter like that.

I saw an offer for a used vc-5070 for 25€ around where I live. It has the features I need: continuity-sound, exchangable Messleitungen/wires (I need clamps very often).

Good idea for my use case? Is a cheap new one better? Do older models have some quirks that make them difficult/dangerous to use for beginners like me?

1. Has somebody experience with them?
2. Can somebody say something about the "quality of their engineering"? I am currently getting into microelectronics and wanna learn by examples, but obviously I can't say whether something is the equivalent of clean or spaghetti code

So my late uncle was working at Siemens and had a "little" home workshop/lab with resistors, capacitors, ICs, switches, soldering boards, wires and what there is. He learned something regarding radio (german: Nachrichtentechniker I think). Among others there was a self built radio clock (that got quite warm, plugged it out bc of safety concerns)

Now I am getting into microelectronics and roughly know what there is. But I only know that I should not use the leaded soldering tin (bc lead) - is there anything else that is unsafe because of old standards or aging? What should be safe to use?

One thing that makes streetcomplete a bit of a chore for me is entering opening times: depending on where you are, you might have to specify it differently for every single day, resulting in a lot of typing. That is more time I stare at my phone and use my hands in an unergonomic position, leading to soreness in neck, hands etc.

So I was thinking: Surely we are technically able to extract those data from an image?

If I would have time to implement it (which unfortunately I won't I think) I'd just try to find a prompt that works well, send it to an LLM like Mistral (bc. in EU), get the info back, let it get checked by the user and then enter it to openstreetmaps. That would require only me to provide my api token, which I would be willing to pay for (assuming my estimation of this being in the cents volume are right).

Now:

1. Does something like that exist and I just don't know about it?
2. If somebody is willing to try that out I can provide some example data, collect more and test it.

Recently I was quite delighted to find out that galaxus.de has a "country of origin" filter. The delight quickly faded when I realized that it was quite unreliable, e.g. one size of a USB stick was made supposedly made in Germany while another was supposedly made in China (which I found quite unbelievable). To be fair, they do write "Specifications may include unverified machine translations."

Does anybody know of a (tech or other) online shop where this works? Or tipps how to quicker navigate real and fake/mistaken "country of origin" labels?
