This time I decided to experiment again with batteries in a less common size. Read on to find out what I got (and didn't get) in the end.

Continuing to experiment with e-cigarettes, I decided to order a few different e-liquids to try. I know quite a lot of people make their own, but there are still people like me who usually buy them. Anyway, read on.

While a review of a DVB-T2 tuner was a fairly unusual topic for this site, a review of a TV box won't surprise anyone. These devices have become very widespread, and in this review I'll try to tell you about one of them from the perspective of someone who hadn't used anything like this before. If you'd like to read about it and see photos of the outside and inside, read on.

Not long ago, I posted a review of a small flashlight. In that review, I described a problem with the flashlight, specifically its faulty, unusable driver. Read on to see how I dealt with it. It won't be very long, but I think it'll be useful.

In September, I posted a review of RFID key fobs, and now it's time to review something these fobs are often used with. Interested? Come on in.

Just recently, TrustFire came up in one of my battery reviews. I had just received some batteries from this very brand, and they were 18650s. This review won't be very long, but it may be useful. As always, the rest is after the jump.

I often use various power supplies in my work, mainly to power video surveillance systems. I mostly use products from a well-known brand, but they’re quite expensive these days, so I wanted to try (and test) an alternative high-power 12 V power supply. Read on for the description, photos, and conclusions.

I use a variety of tools in my work, but one of the most important tools for an electronics engineer is a soldering iron—perhaps the most important one. Soldering irons come in many different types. I mentioned one version of a mini soldering station in one of my reviews a while back. But I also have a second soldering station, which also needs consumables in the form of tips. That's what this article is about.

I often need to quickly check the temperature of electronic components while working. I used to use a homemade contact thermometer with a DS1821 sensor. It was fairly accurate, but the contact measurement method has its drawbacks, so I ordered a small non-contact thermometer. If you're interested, the description and photos are below.

When I first started exploring Chinese online stores, I already wanted to buy a tuner for receiving digital TV broadcasts. But since using these tuners could cause problems here in our country, I didn't want to take the risk. When I was offered another product to review, I couldn't resist this time and decided to give it a try. If you'd like to hear the rest of the story and see photos of the outside and inside, read on.
