For quite some time now, I’ve been using a homemade meter for measuring capacitor capacitance and ESR, built from a circuit designed by GO, a member of the ProRadio forum. I also use another, equally popular meter, the FCL from the cqham website. Today’s review is of a device that claims higher accuracy and, in practice, combines the two meters mentioned above. Warning: lots of photos, little text. This may be an issue for users on expensive data plans.

I've already reviewed TV boxes based on SoCs from Amlogic, Rockchip, Realtek, and even ZTE, but this is the first time I've had a device with an AllWinner processor in my hands. It's also my first TV box from Zidoo, a company I've heard more good than bad things about. So today we'll take apart, test, and inspect the H6 Pro from Zidoo, powered by an AllWinner H6 SoC.

I mention Mean Well power supplies very often in my reviews, and even more often in the comments. Their products occupy a segment where the price is not exorbitant, but the quality is very high. One of my regular readers sent me this power supply specifically for testing, and I’m very grateful to him for that. He also asked me to put it through its paces, which is exactly what I’ll be doing today. So, if you’re interested in branded but not exactly cheap power supplies, I don’t think you’ll be disappointed.

This is the third and, for now, final review in a series about used power supplies for various DIY projects. Today I’ll tell you how a power supply can sometimes turn out, when tested, to be an “overclocked” version of a simpler PSU. I hope you’ll find this interesting—or at least useful. Tests, schematics, and other nonsense as always after the jump.

As it happens, I often need to use a couple of devices with HDMI outputs at the same time, but my monitor has only one input. So I decided to make switching between sources a little easier. I used to solve this by using the monitor’s second, VGA input. Then I got more devices with HDMI, so I had to use an HDMI-to-VGA converter. Eventually I got tired of that and picked up an HDMI signal switch for myself—and to review. So, here’s another short review

As I mentioned in my previous review, I received several different power supplies, and today I’m reviewing the next one. Last time it was a 12 V power supply, but today’s model has a less common output voltage: 48 V. It still has its own area of application, which I’ll discuss at the end of the review. As usual, I’ll cover the tests and circuit diagrams, and answer some of the questions people asked in the comments.

It's been a while since I reviewed a memory card. To be precise, I've only reviewed two: 32 GB and 64 GB cards. This time I decided to try a 128 GB card. I got it to test devices, since prices for cards of this capacity are gradually coming down, and users increasingly want to use them in dash cams, tablets, and so on. Naturally, people ask questions like, “Will it work with a 128 GB card?” So today, another short (really short) review of a small memory card.

Many readers know how much I enjoy writing reviews of power supplies. As it happens, I recently got my hands on quite a few of these devices. The thing is, not long ago a well-known store started offering a variety of power supplies pulled from equipment, and today I’ll tell you about one of them.

Another TV box has landed in my hands. Although it’s based on an SoC from the well-known Amlogic, this isn’t the all-too-familiar S905/912, but something new to me called the T962E. It’s a rather contradictory TV box. Find out more in the review, which, as usual, includes testing, a teardown, and more.

Beelink decided to release an “upgraded” version of the GT1, called Ultimate. In essence, the difference from the previous version isn’t that great, and that’s exactly what I wanted to talk about in today’s review. Let’s see whether it’s worth it, or if they should have just “left well enough alone.”

Quite recently, I reviewed a TV box based on the relatively new Amlogic S905W SoC, which was intended as a budget alternative to the S905X. Back then, I complained about a few issues with the new processor, so today I'm giving it a second try, so to speak, for comparison. As usual, I'll take a look, take it apart, test it, and add it to the comparison table at the end—especially since there's a new entry in it.

Not long ago, I reviewed a USB tester with a certain “feature.” The comments on both the review and the video sparked quite a heated discussion, and today I’ll try to explain what was going on. So, scandals, intrigue, investigations.

I was gradually running out of free disk space, so I decided to expand my “living space.” I also remembered that I had an M.2 SSD lying around since spring, along with an adapter that, as it turned out, I’d bought by mistake. After browsing AliExpress, I found a suitable option—or, more precisely, the cheapest suitable one—and ordered it. So today, here’s a mini-review of a simple little thing: an mSATA-to-M.2 adapter.

Not long ago, someone asked me in the comments about TV boxes based on ZTE Microelectronics’ new ZX296716 SoC. It caught my interest because it’s not the familiar Amlogic or Rockchip, or even the relatively uncommon Realtek. Since I had the chance, I ordered one for review.

At first, I wanted to title this review something like “yet another smartwatch,” but that doesn’t quite fit what I’m reviewing here. “Fitness tracker” doesn’t seem quite right either. That’s because this watch isn’t really “smart” yet, but it’s clearly more than just a fitness tracker. So today’s review is about a fitness watch from WeLoop.

A few power banks for 8 18650 cells crossed my path. I ended up bringing one home to my workbench “for testing,” which is what I’ll be talking about in today’s mini-review. I should probably warn you right away that this power bank has basically just one notable feature: it can hold a large number of batteries. Otherwise, it’s pretty basic and doesn’t really do much.

I'll post coupons here once a day for a limited quantity of products, along with the time each coupon becomes active.

Not long ago, I published a review of the interesting Thor Plus from Vernee. After reading it, one of my readers became interested in the phone and also asked about another very similar model, the Lenovo P2. After reading up on this smartphone, I was surprised by two things: how I had managed to overlook it before, and how closely its main advertised features matched those of the Vernee. So I ordered one, and after testing it, I never once regretted taking a closer look.
