Electronics and technology blog    /    Materials for March 2017 year

Buying this TV box was a bit of a gamble, partly because of the new processor and partly because of some features you don't get with other TV boxes. But in any case, I just wanted to give it a try and check out the new "hardware". Let's take a look, put it through its paces, and take it apart.

Not long ago, I posted a review of a 360 W power supply. I mentioned then that I was waiting for a package with a couple more power supplies, but more powerful ones. The package has arrived, and I finally got around to the first one: a 480 W model. So far, this is the most powerful power supply I’ve reviewed (apart from bench power supplies), and it also has some notable differences from the previous ones. But as usual, I’ll take a look, tear it down, and test it.

Today's mini-review is about four different camera batteries. They look different, but their specifications are remarkably similar. Still, it's better to see for yourself.

At the end of last year, I published a review of a basic video surveillance kit consisting of four IP cameras and a DVR. At the time, someone also “hinted” that there was an alternative in the form of AHD cameras. In this review, I’ll try to explain what AHD is, how it works, and what the standard is all about.

Last month I posted a review of the Szsinocam camera, and mentioned then that I was planning to write another review on the subject. In the end, I decided not just to review one camera, but to compare it in part not only with the Szsinocam, but also with a camera from the well-known Hikvision brand. Hope you find it interesting :)

Some time ago, I got my hands on a rather interesting smartphone. Somehow, I never got around to telling you about it. Time went by, and every now and then I sat down to work on the review, but I only decided to finish it now. But first things first.

Today's brief review is about a fairly ordinary tool: drill bits. There's not much to say about them, and what could you possibly tell people about a small twist drill bit that they don't already know? Still, as usual, I'll take a look at them and try to put them through some kind of test :)

I’d come across information several times about connecting a smartphone or tablet to a TV using something like AirPlay/DLNA/Miracast. I got curious, bought one, gave it a try, and decided to tell you about it :)

Continuing my series on power supplies, I ordered another one, this time more powerful than the previous one. This review won't be very long, but as always, I'll inspect it, take it apart, and test it.

I've taken apart and tested quite a few small computers and tablets, and I can say with confidence that overheating is the bane of the vast majority of these devices. But not long ago, I got my hands on a device that doesn't overheat, and I was pleasantly surprised. But is everything else just as good? Let's take a look, test it, and take it apart—as usual.

I was browsing the Gearbest website and happened to come across this flash drive. I liked that it has two different connectors. Since both types of connection are common these days, I thought it might come in handy. And then, as usual, I ordered it, received it, and put together a short review :)
