I was browsing the Gearbest website and happened to come across this flash drive. I liked that it has two different connectors. Since both types of connection are common these days, I thought it might come in handy. And then, as usual, I ordered it, received it, and put together a short review :)

I've reviewed quite a few different power supplies, and this is probably my favorite topic. But somehow I've almost completely overlooked one category of devices: uninterruptible power supplies, even though I do have one review on the subject. The device made a good first impression, but the reality turned out to be considerably more complicated. Anyway, as always, more after the jump.

I happened to come across several IP cameras at a well-known store and decided to try one out. You can find out what I ended up "trying out", as well as what it looks like inside and out, in this review.

Today I decided to write a short review of my latest batch of the well-known Panasonic NCR18650B batteries with protection. I thought it was a useful topic, so I decided to share my experience.

My first—and until recently, only—jigsaw came along about 8 years ago. It helped me out quite a lot and got a little "tired," so I wanted to get it something newer and possibly better to help out. Today I'm going to talk about a STANLEY jigsaw, although things aren't quite that simple.

I've already posted several reviews of different soldering irons, from the simplest to some pretty sophisticated models. This time, though, I'll be looking at a more versatile option in this category of tools for electronics hobbyists.

Somehow, despite using a relatively large number of mobile devices, I get by without any extra “power banks.” Though it would be more accurate to say I get by without the kind most people are used to, since I do have a 12 V version. In this case, I was simply offered this Powerbank to review, and I thought—why not? At the very least, I can see how it’s made. As always, next up: inspection, teardown, testing, and modifications.

It's been a while since I last wrote about power supplies, even though they're one of my favorite topics. I also somehow overlooked power supplies with the common output voltage of 12 V. This time, I decided to kill two birds with one stone and take a look inside a 12 V power supply with passive cooling. As always, the inspection, tests, and conclusions are below the fold.

I once wrote a review of a cordless drill from MILWAUKEE, where I described modifying its original charger. Here, I decided to put the modification instructions in a separate, short post.

About a year and a half ago, I wrote an article about a homemade (well, almost) electronic load, and I’ve finally decided to take the project further.

Today I’ll talk about the simplest kind of power supply—more specifically, how to calculate its capacitor value and choose the right type. I’ll also suggest some better options for low-power supplies.

Today I’m going to tell you about a small charger that doesn’t quite live up to its advertised specs, even though it’s put together pretty well. Teardown, tests, conclusions—as always.

I came across some small protection boards for packs made from two lithium batteries, so I decided to put together a little review—or a big photo dump, whichever you prefer :)

I've handled quite a lot of different power supplies, but every now and then I come across an epic case that I just have to tell you about.

With this short article, I’m starting a series about repairing various devices that occasionally end up on my workbench. The first article will be about repairing a 5 V, 60 A power supply. I’m also planning to publish articles for beginners, so I’d be interested to know what readers would like to learn about.

I came across a rather interesting wireless keyboard the other day—or, to be more precise, a keyboard + remote + learning remote + air mouse. Today, I’ll tell you about this four-in-one device in my review, and of course show you what it looks like both inside and out.

A few months ago, I finally "moved" to a new computer, and during the "break-in" period I ran into a problem caused by the nature of my work. Inspection, tests, and an explanation, as always, after the jump.

About a year ago, I published an in-depth review of a thermal imager. It’s an interesting and very useful device. Then, while browsing the website of a Chinese store, I happened to come across a very attractive price for this instrument.
