In this review, I’ll try to compare and test a range of batteries. As it turned out, the review includes not only lithium batteries, but mostly the familiar “18650” cells. There’s also one rather unusual battery. If you’re interested, read on. Warning: this is a very long review and may be a problem for users on metered connections.

Today I'm reviewing something radically different from my previous subjects. Not only because of its modest size, but also because the item I'm reviewing is completely outside my usual area. But I liked this kitten—and so did others—and I wanted to tell you about it.

I got my hands on a somewhat unusual instrument—or, more precisely, one with an unusual feature. This multimeter can wirelessly transmit measurement results to remote devices via Bluetooth. There’s already a review of this instrument here, so mine will be more of a brief supplement, where I’ll talk about its strengths and weaknesses.

Today I'm reviewing a small Android tablet. Somehow, I've usually reviewed tablets running either Windows or Windows + Android, but this time I decided to see what a relatively inexpensive Android-only tablet is like.

Computers based on the Atom Z8x00 have been on the market for almost a year. Somehow, though, most of the devices I’ve had for review were based on the Atom Z8300, with one based on the Atom Z8500. I still hadn’t tested a device with the top-of-the-line (if you can call it that) Atom X7-Z8700. Today, I’m going to fill that gap in my testing: on my operating table is the Beelink BT7, one of the very few computers equipped with the Atom X7-Z8700. A look around, some tests, and the usual teardown and modifications.

Back in May, I reviewed a small computer that I’m planning to use to replace my old one. To increase the available storage, I decided to buy a 240 GB SSD. So, here’s a brief review of a small SSD.

A friend asked me to buy him an inexpensive TV box. It was no trouble, and I was also interested in tinkering with one for the sake of the stats. So here’s another short review, this time of a TV box built around the already familiar S905 SoC.

It all started about six months ago, when my daughter's Samsung Galaxy battery started dying again. Since the phone was outdated both in terms of hardware and software, we started looking for a replacement. Around April, I spotted the Vernee Thor among the new releases, and it really caught my eye. I asked if I could get one to review, and they sent it over. As always, I'll take a look, take it apart, run some tests, and share my impressions after a month of use.

Some time ago, I posted a review of a mini PC based on the Celeron J1900. In that review, I mentioned its more powerful “siblings” based on I3 and I5 processors, which had a few design “quirks” of their own. After keeping an eye on how the Onda M2 performed, I finally decided to replace my old computer with something more compact and more powerful. In this review, I’ll try to show why I chose this particular option and what it’s all about.

It all started when I decided to make a major move from my old computer to a new one, and I decided to start with the drive. Since this is expected to be a major overhaul, there won't actually be a direct replacement; the old drives will most likely be moved somewhere else entirely. So this will just be an inspection, some tests, and, as always, a teardown.

Not long ago, Gearbest had a sale. I spotted a few things that caught my eye, so I decided to pick them up too. While the rest is still on its way, today I'll write about what has already arrived. Inspection, teardown, tests and analysis, as always, in the usual place :)

I recently posted a review of a TV box based on the new RK3229, and today I have a more interesting version of a box with the same processor on my desk. Unfortunately (or perhaps fortunately), it runs the same Android version, 4.4. As usual, we'll take it apart, inspect it, and test it.

I know my readers prefer reviews about amateur radio, and that will be the next one, so bear with me a little. :) But today I have a TV box on my desk, combining the new RK3229 processor with the familiar Android version 4.4. As always, a full teardown, tests, and analysis.

I've already reviewed quite a few mini PCs running Windows. But then I came across a relatively inexpensive model and decided to see what mini PCs in the lower price range have to offer. As usual, though, this turned into the whole routine: inspection, tests, teardown, modifications, setup, and more tests.

I've already reviewed several kits that let you build all sorts of useful things for radio enthusiasts. But today I'm reviewing a bigger kit. We'll try to build a recent invention: a 3D printer. I can't say it all went smoothly. I kept expecting something to go wrong, but in the end, I managed to put something together. Anyway, a description of what this is and an attempt at a step-by-step guide are below the fold.

ONDA, a company known for its tablets, apparently decided not to stop at making these devices and set its sights on the small desktop computer market. Today, I’ll tell you about one of these devices. As always, there’ll be a look around, some tests, a teardown, and a few more hurdles to overcome.

While the big, important reviews are in the works, I decided to put together a short review/report in the “Look what arrived” series. So, today’s review is a test of SANYO UR18650ZY batteries. If you’re interested, come on in.

Quite a few of my readers probably remember my review of one of the smallest computers, the MeeGoPad T02. The review was probably remembered less for its description of the computer than for the difficulties I ran into while modifying it. Although I did manage to get the better of it back then, it wasn't easy. When I saw an updated version of this computer, I couldn't pass it up. I was curious to see whether it really was any better. Anyway, if you're interested, come on in. :)
