I ordered these batteries for a friend and borrowed a few for testing, so I decided to put together a short review in case it might be useful. These batteries come up in the comments quite often, after all.
HT-A2 thermal imager with a resolution of 320 × 240 pixels
18-05-2021, 12:05
About five years ago, I published a review of a thermal imager, and now it’s time to update it. I looked at various models, but in the end decided on the HT-A2 from Hti. I ordered one, received it, used it for a while, and decided to put together a short review.
EleksTube IPS Desktop Clock
Last year, I posted a preview of these rather interesting clocks and mentioned that I planned to buy them. They took quite a while to arrive, and then I didn't have a chance to write a review. But I finally got around to it and decided to show you what these clocks are all about.
Makita 18 V cordless drill/driver

The story behind this order is very simple: I spotted an interesting, inexpensive drill/driver and thought it might be worth a look. But, as sometimes happens, "something went wrong". Still, in reality, things turned out not so badly, but even so...

Another module from Novatek. This time, I'll take a look at a device for reading measurements from various types of sensors and using them in automation systems, with the option to send the data to a PC as well. Inspection, teardown, tests, conclusions.

One of my readers sent me this battery, and I’m very grateful to him for it. It’s not brand-new and has a few quirks, but as always, you can find out more in the review.
4S Capacitor Balancer and a Little About How It Works
11-05-2021, 10:23
This is my third review of an active balancer and my second review of a capacitor-based one, also known as a capacitive balancer. Last time, I focused more on how it performs, but said almost nothing about how it works. Today, I’ll make up for that omission.
Three-phase automatic transfer switch controller PEF-321AVR from Novatek-Electro
6-05-2021, 03:35
Today I have an ATS on my desk—short for Automatic Transfer Switch. In simple terms, it’s a device that automates the switch from the main line to a backup line if a problem occurs with the main supply. And since this is a microcontroller-based device, it naturally offers more features and capabilities, which is what I’ll cover in this review.
