About six months ago, I reviewed a small but interesting TV box called the Mini M8S. Not long ago, an updated version of this device was released, featuring an S905X processor. I was curious to see how it differed, so I bought one, took a look, and took it apart. Details under the spoiler :)

It’s no secret that a cordless screwdriver is a useful tool around the house, so I decided to test—and, more interestingly, compare—these two tools from a Chinese brand with the rather odd name LOM YUM. This review covers everything: an inspection, teardown, tests, a comparison, and a small bonus.

A short review of another smartphone. I’d like to say it’s another small one, but in my opinion, 5 inches still doesn’t qualify as “small”—though who knows what tomorrow will bring. As always: inspection, teardown, tests, and conclusions.

There are lots of phone models, and new ones keep coming out all the time: big and small, fast and slow, good and not so good. But I always want to see how Chinese engineers have put together the latest mobile companion, so that's what I'll be doing in this review. If you're interested, come on in.

In this review, I’ll try to compare and test a range of batteries. As it turned out, the review includes not only lithium batteries, but mostly the familiar “18650” cells. There’s also one rather unusual battery. If you’re interested, read on. Warning: this is a very long review and may be a problem for users on metered connections.

Today I'm reviewing something radically different from my previous subjects. Not only because of its modest size, but also because the item I'm reviewing is completely outside my usual area. But I liked this kitten—and so did others—and I wanted to tell you about it.

I think some readers still remember my review of a kit for building a linear bench power supply. Despite a few shortcomings, the board turned out to be quite interesting. When a friend sent me a link to the kit reviewed here, my first thought was, “That’s the same board.” But in reality, things turned out a little differently. Anyway, if you’re interested in this kind of thing and want to find out how to build a small bench power supply, read on.
