Electronics and technology blog    /    Materials for July 2015 year

Many people are already used to computers constantly getting smaller. So when I saw this tiny computer, I immediately wanted to get one to review. Especially since people had already asked me whether I’d tried it. Now I can confidently say that I have—and not only tried it, but also taken it apart and modified it, because this computer turned out to have a mind of its own. Anyway, if you’re interested in my whole saga, read on.

In April, I reviewed a pretty interesting, well-made 12 V power supply. I was really impressed by its value for money. But people asked in the comments and later in private messages about the same power supply, but with a 24 V output. With this review, I'll try to answer that request and show you what it's like.

After seeing that the girls had even started adding lighting to the kitchen, I decided to put my soldering iron aside too and write a counter-review of a product that's unusual for me: a women's handbag. Handbags come in all shapes and sizes—big and small, white and black, green and blue, with long or short handles—but a handbag is almost always an essential accessory for women. And there's no need to mention that different seasons and outfits call for different handbags. So, as always: a look around, some photos, and a bit of tweaking :)

Many of you are probably familiar with this situation: at the worst possible moment, your camera (and plenty of other devices) says, “Battery depleted”—and it doesn’t care that you only have a couple of shots left to take. Batteries usually come in genuine and clone versions; this review is about the latter.

It all started when the power supply for my old tablet began acting up, so I decided to find a replacement. I found one with the familiar plug and a non-detachable cable. I’ll probably repair the old power supply—I’ve already thought of a use for it—and today I’ll try testing the new one.

This is the fourth article in a series about building a rather specialized device: a powerful electronic load. I’d been planning to publish it for a long time, but somehow never got around to finishing the device.

Since reviews of mini PCs have been appearing fairly often, I decided to write a somewhat expanded review of this kind of device. I decided to expand it by looking at a possible use for this mini PC. Since I often have to work with video surveillance systems, I'll focus the review in that direction. But first things first; let's stick to tradition.

Yes, you read that right: I’ve already reviewed these batteries, including putting them to use. But this review is different from the previous one. I’ll also answer some questions that readers often ask about products received for review. Anyway, if you’re interested, the rest is as always below the fold.
