While the big, important reviews are in the works, I decided to put together a short review/report in the “Look what arrived” series. So, today’s review is a test of SANYO UR18650ZY batteries. If you’re interested, come on in.

Quite a few of my readers probably remember my review of one of the smallest computers, the MeeGoPad T02. The review was probably remembered less for its description of the computer than for the difficulties I ran into while modifying it. Although I did manage to get the better of it back then, it wasn't easy. When I saw an updated version of this computer, I couldn't pass it up. I was curious to see whether it really was any better. Anyway, if you're interested, come on in. :)

Today I’m reviewing another kit that lets you build a multichannel voltage converter. Some time ago, at readers’ request, I ordered several different voltage converters. I chose the one I’m reviewing today myself, just out of curiosity—I wanted to see what it was, and thought it might come in handy for someone. Photos, schematics, tests—everything as usual :)

Many of you have probably heard the name thermal imager. Some of you may have seen one in movies or various technical programs, but I doubt many people know what it is or how it works. In this review, I’ll try to explain in plain language what this device is. As always, I’ll cover everything: a description, a short test, and a teardown.

In my reviews, I often mention that I try to use plug-in connections. Of course, soldering is very reliable, but it’s not always convenient. Today’s review is about one type of connector. But since I can hardly claim to have anything new to say, this is more of a “look what just arrived” kind of review :)

This review continues the previous one, but since doing two reviews in a row about the same product would be somewhat illogical and inappropriate, at least the opening will focus on one of the interesting parts I bought for the future power supply.

About a year and a half ago, I reviewed a project using the smaller DC-DC converter board from the ZXY60xxS family. The power supply is in good shape and works perfectly well. But after using it for a while, I realized I wanted something different. So about a year ago, I started designing a more practical power supply (at least for my needs). Anyway, if you're curious what I cobbled together in the end, read on. Warning: lots of traffic, lots of photos.
