Electronics and technology blog    /    Materials for October 2018 year

Today I'm reviewing a rather interesting and useful device, if it weren't for a few "buts" that slightly spoiled my overall impression of what is, all things considered, a pretty decent piece of hardware. I'm talking about an eight-channel relay module with remote control over Ethernet.

Gearbest has provided coupons for Hystou and Beelink computers.

I've been meaning to start this topic for a long time. I could have called it something like "Top 100 Best Products," but I don't want to write another cookie-cutter list, so it'll simply be called Popular and Useful Products. I'll be posting links here to various products that may interest electronics enthusiasts (mostly) and blog visitors in general. Some of the products will be ones I've tested myself; the only difference may be the seller.

Another batch of holders for 18650 batteries arrived recently, so I decided to put together a short review in case it comes in handy for someone. I've reviewed similar holders several times before, so this one is more of a follow-up to the previous reviews.

Somehow, despite having more than 35 years of experience with a soldering iron, I had never used soldering paste, although I’d heard a lot about it. So I decided to fill that gap by picking up a tube of one product from this large family for review: Best BS-706 paste. If you’re interested in my first attempts at using soldering paste and what I thought of it, come on in.

Today I’m reviewing another TV box from Mecool, built around the long-familiar S912 SoC. There’s nothing unusual about it, except for a slight sense of déjà vu that stayed with me while using the box, especially when inspecting it. Why? Read on for the review, which, as always, includes an inspection, a teardown, a few tests, and my conclusions.

I’ve already posted a review of a very similar device once before—the title was almost the same, too. This time, though, the little meter is a bit cheaper, and its quality is definitely no worse than the previous one. So, here’s a quick review of a useful little gadget for electronics hobbyists.

GearBest is having a sale on an interesting TV box model built around a Realtek processor.

Power banks are pretty rare subjects in my reviews. Somehow, I hardly ever use them in everyday life, but when I was offered the chance to review one, I decided not to turn it down. As usual, this review covers the exterior, teardown, tests, and conclusions.

I sometimes order small meters for battery packs, and I finally got around to testing them and writing a mini-review. A look at the device, a few tests, and some conclusions. I hope you find it useful.

I ordered this meter quite a while ago from a different store, but after browsing AliExpress I found a listing for a device that looks exactly the same. Since I'm almost certain they all come from the same basement large factory, here's a link to another store.

I've had this display lying around for quite a while, but I've only just gotten around to writing a review. I probably won't have much that's new to say, since this type of display is so common that it's hard to find a radio hobbyist who hasn't heard of it. The only difference from the popular 1602 and 2004 models is that this one has 16 characters across four lines.
