Electronics and technology blog    /    Materials for August 2020 year

In the spring, I published two reviews of Vapcell batteries, both conventional lithium-ion and LiFePO4. Now I’ve got another batch of cells with this company’s logo. To avoid overwhelming readers with too many reviews, I split the batteries into several groups. Today I’m reviewing the first group.

It's been quite a while since I last posted a product roundup, so today I decided to make up for it. There won't be too many products, but I've tried to pick out ones that might be interesting, including some I've bought myself. That doesn't mean you can't share links to products you think might be interesting, too.

A flashlight that is clearly trying to look like the original Nitecore Tube

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.
