Electronics and technology blog    /    Materials for February 2017 year

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.
