Electronics and technology blog    /    Materials for November 2024 year

Some time ago, I published a roundup of various products and included a nice-looking multimeter that can measure inductance. I also decided to buy one to review and test it, thinking it might be useful. Well, I received it yesterday, tested it, and decided to write a review while it was still fresh in my mind.

This article came about spontaneously. A few days ago, a friend messaged me saying his Mean Well UPS had stopped working: it runs for about an hour and a half, then shuts off, even though the battery is supposedly 12+12 Ah. By the way, this is the same friend who had previously sent me another Mean Well UPS to turn into a UPS :)

While putting together a list of products for the 11.11 sale, I spotted some interesting gadgets: bumpers for Riden power supplies. Yes, they’re highly specialized and somewhat controversial, but this time, along with the work-related orders, I wanted to buy something “just for fun”—and I think I made the right call.

I hadn't kept up with the latest additions to the range of converters on AliExpress for a while, but then the app showed me something new. I got curious, started looking into it, and it turned out there were some interesting new products. And as a bonus, here's a few other little things that might come in handy too.

We all know that sellers often pull a fast one during sales, but sometimes there are genuine discounts. Since I know the prices of some products pretty well, I can tell right away whether a discount is real. Anyway, if you’ve been looking for a DL24MP electronic load at a good price, this is the place to go.

The traditional 11.11 sale is coming up, so I decided to put together a bunch of links to products I came across over the year since the last sale. Some are products I bought myself or added to my cart but never got around to ordering, while others are simply things I thought might be useful or interesting.

Not long ago, I showed a new version of an electronic load. In a sense, it’s a downgrade—a step backward rather than forward—but it’s not that simple, so I decided to put together a short article.
