The second part of my introduction to Light Route products. In the previous part, I covered 60 W power supplies with 12 V and 24 V outputs. Today, I’ll be looking at drivers for powering high-power LED modules used in lights, floodlights, and street lamps.

Not long ago, I published a review of a board for building a simple spot welder powered by supercapacitors. Today, I’m continuing that series: I’ll tell you about a much more capable device and, along the way, build a welder based on it.

I found a few coupons, possibly even useful ones, for several products

As it happened, I got my hands on a simple clamp meter, which is what I’ll be reviewing today. I’ll try to keep this brief while still covering the inspection and tests.

A friend recently asked me to test a small battery for quadcopters and similar toys. I was curious, so that’s how I came up with the topic for today’s review.

I ordered some things from Taobao not long ago and needed something to fill out the package. I spotted these tweezers and ordered one to try, just out of curiosity. This is probably one of the shortest reviews ever :)

Today I'm reviewing a product that isn't exactly unusual, but is definitely quite rare. In general, based on my personal observations, the number of reviews of devices for industrial and specialized applications is close to zero, and with this review I want to help fill that gap a little. So today I have a rather interesting gadget on my desk with a complicated name: an Electrical Parameter Recorder.

I've reviewed quite a large number of different power supplies by now, but today's review is a little different. No, the power supplies themselves are much the same; the difference is the manufacturer. If I'm not mistaken, this is my first review of power supplies made in Ukraine.

There are a few discounts on various soldering and welding tools; this may be useful to someone.

It’s been a while since I posted a power tool review, and now I’ve got my hands on a cordless angle grinder designed for standard Makita batteries—and it also has a brushless motor. Today I’ll take a look inside, take it apart, run a few tests, and include a small bonus.

Banggood is running some promotions right now, with stars to collect, and while browsing I kept coming across this impact wrench at what seemed like a reasonable price. I don't actually need one, but a few times I nearly bought it. I thought it might be useful to someone.

I think many of my readers remember that I often test batteries, and for quite a while I've also had my eye on a dedicated battery tester. Yes, friends, today we're talking about the EBC-X electronic load and tester, which I finally bought :)

Like many people, I have a WiFi router at home for tablets, laptops, and lately various IoT (Internet of Things) devices. But because of the apartment's layout and the less-than-ideal placement of the router, the connection is poor in some areas, so I decided to improve things a little by installing a WiFi repeater.

Discounts on both models of Ruideng adjustable voltage converters

Last fall, a very interesting adjustable voltage converter, the RD6006, went on sale. It stood out from previous models with its large display, convenient controls, battery charging function, and WiFi connectivity. But discussions soon started: 60 V is certainly nice, but 6 A is a bit on the low side. The manufacturer replied, “Don’t worry, a more powerful version will be out in about six months.” In fact, it took longer, mostly because of the virus, but the manufacturer didn’t abandon development, and today I’m reviewing the version with an output current of up to 12 A.

Lately, I’ve been seeing quite a few reviews where people either build spot welders or use them in their projects to assemble battery packs. I’ve got one of these devices myself now, though it’s quite different from the ones I’ve seen before.

Today, a very brief review of a fairly ordinary voltmeter, but one that can be mounted on a DIN rail—that's actually one of its main distinguishing features. As always, the review includes an inspection, tests, a teardown, and an explanation of why I needed it.

Some time ago, a new version of the converter called the RD6012 went on sale. Since it also needs a power supply, I ordered a suitable one from the same store—in this case, an 800 W unit with an output voltage of 70 V. This review won't be very long. You'll see why as we go, but there will still be some tests.
