I picked up a USB hub and a Bluetooth adapter in a recent sale and thought I’d share my impressions in case they’re useful to someone :)

I’d already been asked about this device, and that’s exactly why I ordered one—to get a hands-on look at it. This time, I’ll be looking at a power limiter for connected devices. It can help when the combined power draw of the connected loads might exceed the available power limit.

Another power supply from Sanmim, but this time it's very compact, though not particularly powerful. As this review shows, it has plenty of interesting features. Inspection, tests, schematic, conclusions.

At first, as before, I wanted to write two reviews, one for each type of battery. But then I thought: the batteries have similar specs, so why not combine the two reviews into one? So today, it’s a “two-in-one” review, plus a comparison.

Another review in the “nano” series, and this time it’s about a very useful little item to have around: fasteners.

It's been quite a while since I last tinkered with Novatek devices, and now I've got several candidates for review. Today we're looking at a multifunctional relay that combines several devices in one, but as always, more details in the review.

Today I have a nano-review of caps for push buttons, also known as “tact switches” or “tactile switches”—whichever term you prefer.

I've had all kinds of batteries: standard ones, protected ones, ones with a converter, and even one with a built-in charger. But this is the first time I've come across a battery this unusual. Inspection, tests, and conclusions.

Another set of 18650 batteries. They don't really stand out among the dozens I've tested, except for their slightly higher rated capacity and lower current rating than the well-known VTC6, HG2, and 30Q, which I'll compare them with at the end of the review.

It's been a while since I wrote a "not a review," and a friend just sent me a link to a new product from Atorch, the logical continuation of the DL24 series. I wrote about it earlier in a similar "not a review" and in a more in-depth article with an example of how to build a power module for it. So today, here's a brief announcement of their new product.

Another power supply I was asked to test. I was interested in it myself, so I ordered one for a review. As usual: inspection, schematic, tests, conclusions.

Not long ago, one of the blog's readers asked me to help sell some voltage converters. I thought, why not? Someone might find them useful, so I put together a short overview to explain what we're talking about.

Another pair of 21700 batteries, but this time in the high-capacity class, which I also have something to compare them with. Besides, in my opinion, batteries like these are currently one of the fastest-developing segments, since they offer high capacity, decent current, and a wide range of applications.

Not long ago, I posted a review of my new compact soldering station, and afterward someone recommended replacing the handle with something more comfortable. I found one of the fairly well-known options, ordered it, gave it a try, and here are my thoughts :)

Another set of high-current 21700 batteries, with a capacity of 4000mAh. This is already my fourth review of batteries with similar specs, so I have plenty to compare them with—and I’ll do that at the end of the review.

Not long ago, one of my regular readers suggested in the comments that I review an unusual power supply. It caught my interest, so I thought, why not? It certainly stands out from the crowd of common power supplies.

BAK batteries have appeared at the well-known Nkon store, and I've already been asked several times to review batteries from this manufacturer. Well, as it happened, I had a few of them on hand.

Continuing our discussion of multi-component batteries, today I’m reviewing another model with a different form factor and noticeably higher capacity.
