Not long ago, I saw someone mention that there aren't enough reviews of unusual products, so today I'm reviewing just such a product. Though I wouldn't call the product unusual myself, I haven't come across reviews like this, which is why I decided to write one. I've often seen people ask what is used to weld battery packs. Obviously, a special strip is used, but what types are there, how do they differ, and which one is best? That's what I'll try to explain today.

Lately, I’ve been seeing more and more models based on the Amlogic S905W. Although I’ve already tried testing two devices like this, I decided to give it another shot.

Another TV box, but this one belongs to the very lowest price segment. That doesn’t stop me from putting it through all the same tests as its more expensive “colleagues.” As usual, I’ll take a look, take it apart, run some tests, draw conclusions, and finish with a summary table.

Today’s review is about batteries, but not the familiar Li-ion ones—LiFePO4. They’re very similar in many ways, but in fact they have far more differences than you might think at first glance, and I’ll try to explain them.

Last summer I published a review of the MECOOL M8S PRO, which, by and large, differed from the previous models only in having DDR4 RAM. I also compared it with some other models there. This model is a little newer, but its main difference from the previous one is a different remote control. As usual, below the fold you'll find an inspection, teardown, tests, and a few conclusions.

And now it’s the turn of the last, sixth power supply made by Mean Well. I decided to save this one for last, partly because its design stands out from the rest, and partly simply because I liked the way it looks. In any case, I found it interesting to take a closer look, and that’s what I’m going to tell you about today.

I only recently posted a review of the Mean Well HDR-60-12 power supply, and today I'm reviewing its larger "sibling". It's very similar, but it also has a few features of its own. Both power supplies share the same form factor and output voltage—though I'm getting ahead of myself. More on that in the review.

Today I'm reviewing another power supply made by Mean Well. This time, it's a model designed for mounting on a DIN rail. I've already reviewed a similar power supply, but that one was intended for industrial use. This time, I'll show you a more "home-friendly" version. Inspection, schematic, tests—as always.

Not long ago, I promised a review explaining how to add digital control to a linear power supply board. Keeping that promise, today I’m posting a review of the board itself, along with some drawings, the schematic, firmware, and, for the real enthusiasts, the source code.

I needed a small-capacity drive to run a Linux server. After comparing the prices of HDDs and solid-state drives, I chose a budget 32 GB Goldenfir SSD and would like to offer you a brief review of it.

So, today I have the third of six power supplies sent to me by one of my readers. This time, it’s a relatively compact and inexpensive power supply. I’d even say it belongs to the budget range, since in some ways it’s noticeably simpler than the previous ones. But simpler doesn’t always mean worse, and I’ll try to show and explain all of that in this review. Anyway, if you’re interested in branded power supplies, I think you’ll find something new here.

Recently, I published a review of a kit for building an adjustable linear power supply with an output voltage of up to 60 V and current of up to 20 A (at least in theory). Today I’m reviewing a product from the same seller and the same series, but this time it’s not a kit—just a standalone module that can also be used with the control board from the previous kit. But I’ll cover everything in more detail in the review. I’ll also include the schematic for the relay module from the previous review.

Today's review covers a topic that's quite familiar to radio amateurs. There are plenty of reviews of adjustable power supplies, as well as kits for building them. I've posted a couple of similar reviews myself. But today's kit is a little unusual, both in terms of power and circuit design. Of course, radio amateurs have used all these approaches many times before, but this is the first time I've come across them all together in a kit, so that's what I'm going to talk about.

A little over a month ago, I published a review of the AlldoCube Power M3 4G tablet, and today I have its near-identical copy, the VOYO i8 Pro 4G, in my hands. The tablets are indeed very similar, at least on paper, but are they really the same in practice?

I’ve come across computers and TV boxes made by Minix in reviews many times, but this is the first time I’ve had one of the company’s computers on my desk. I’ve read quite a few good reviews of this manufacturer’s devices, but I’ve also had a fair number of computers from other brands pass through my hands, so I was doubly interested to see whether Minix really is any better. Inspection, teardown, tests, summary table, conclusions.

A brief review of a relatively small drive from an unknown (at least to me) company, RECADATA. Nothing extraordinary, just a small SSD. Inspection, tests, and conclusions.
