Electronics and technology blog    /    Materials for May 2016 year

Last month I reviewed the MP2359DJ chip for building a DC-DC converter, and in the comments people suggested a few other similar chips. A little while later, I ordered a couple of different ones for my “assortment,” and recently I received and tested another one.

I'm often asked to recommend a soldering iron that's reasonably priced, offers decent quality, and has temperature control. Recently, I ordered a mini soldering station that might well fit the bill. There are already a couple of reviews of this station on the site, so mine is more of a short addendum to the existing ones.

Some time ago, I posted a review of several types of batteries. This review is a short follow-up, since a couple of the batteries appear in both reviews, although they came from different sellers.

Around March, readers sent me a link to a rather interesting product. And since it’s right up my alley, I ordered one for a review—to try it out myself and show it to everyone else, as they say.

Some time ago, I posted a review of a mini PC based on the Celeron J1900. In that review, I mentioned its more powerful “siblings” based on I3 and I5 processors, which had a few design “quirks” of their own. After keeping an eye on how the Onda M2 performed, I finally decided to replace my old computer with something more compact and more powerful. In this review, I’ll try to show why I chose this particular option and what it’s all about.

Some time ago—or, to be more precise, at the end of February—a seller from one of the AliExpress stores contacted me and asked me to write about his product. Writing about it wasn’t particularly difficult, and the device caught my interest in its own right. At least, at the time I had an idea for how I might use it. Anyway, if you’re interested in reading about a fairly well-known piece of hardware, read on :)

The idea of finding that perfect multimeter has been on my mind for quite a while. I've already reviewed several multimeters, and I'll link to those reviews here. One of them will also feature in this review. But I wanted something good, accurate, and relatively inexpensive. In this review, I'll show you the multimeter I liked and compare it with its smaller sibling.

It all started when I decided to make a major move from my old computer to a new one, and I decided to start with the drive. Since this is expected to be a major overhaul, there won't actually be a direct replacement; the old drives will most likely be moved somewhere else entirely. So this will just be an inspection, some tests, and, as always, a teardown.
