LED panels, controllers, or how to build an LED screen, part two
20-09-2017, 23:04
In the first part of the review, I talked about LED panels and controllers. In this second part, I’ll focus more on the software, testing, and demonstrations. I’ll also talk about the problems I ran into—because of course there were some.
LED panels, controllers, or how to make an LED display, part one
20-09-2017, 22:35
They say that appetite comes with eating, and that’s certainly true. I can confirm it 100%. I’ve already posted two reviews of LED panels—though, more accurately, one review and one follow-up. Today I’ll tell you about higher-resolution LED panels, controllers, and my dealings with the sellers. So brew yourself some coffee or tea, get comfortable, and settle in for a long read. Warning: this review is very long and may be a problem for users on metered connections.
Coolpad Max A8, a decent smartphone with a 5.5-inch screen
3-09-2017, 11:53
I’ve already reviewed quite a few smartphones, but I’d like to start this review by saying that this phone isn’t built around the much-maligned MTK SoC from MediaTek. I don’t mean to say anything bad about it; it’s just that the seemingly bottomless supply of processors from this manufacturer, used in almost every budget phone (and plenty of others), has been mentioned many times already. This time, the “heart” of the phone under review is the Qualcomm Snapdragon 617—not exactly new, but still a pretty decent chip.
Single frames for assembling 18650, 18500, and 18350 battery packs
23-08-2017, 00:48
Not long ago, I posted a review of triple frames for assembling battery packs, and now I’ve finally received the single frames. There’s not much new to say, so this review will be minimalist.
USB tester, meter, or just a number display?
6-08-2017, 23:55
I often see people measuring the capacity of smartphone batteries, power banks, and the like with USB testers in forum comments and reviews. I once tried to explain why measuring them this way makes no sense, but today I’ll approach it from another angle and test the testers themselves.
Vorke V1 Plus Mini PC or the New Version
6-08-2017, 02:33
Last fall, I posted a review of the interesting Vorke V1 mini PC. It’s a pretty good machine: fast, doesn’t overheat, and lets you install a hard drive. Not long ago, an updated version with an Apollo Lake J3455 processor appeared on the market. I got interested, ordered one, and wrote a review. Of course, the review includes a look at the device, tests, a teardown, and a comparison with the previous version.
More LED panels: upgrading the scrolling display
6-08-2017, 01:33
Back in winter, I posted a review of 64x32-pixel RGB LED panels, which gave me a 192x32-pixel scrolling display. But, as I found out once again, the more you have, the more you want, so I decided to double the resolution—not by making it longer, but by making it taller. Anyway, if you're interested in this topic, come on in.
Homgeek, manual mini coffee maker for making espresso/lungo
22-07-2017, 00:57
Today I have a short review of a compact espresso maker. It’s an interesting little device, and in some situations it can even be useful. I’ll tell you all about it in the review, so if you’re curious, read on.
Inexpensive 12.6 V 3 A Charger
22-07-2017, 00:21
Just recently, I posted a couple of reviews of chargers, but as it happened, another one accidentally came my way. Unfortunately, it’s also a 12.6 V charger (for a 3S lithium battery pack), but I decided the review might be useful because of its low price. Alas, it’s not quite what I’d hoped for, but more on that in the review.
Another charger for assembling 3S Li-Ion battery packs
19-07-2017, 22:05
Another review of another small charger for 3S (12.6 V) battery packs. Not long ago, I published a review of the 3 A version; today, it’s a simpler 1 A model. Unfortunately, things didn’t go as planned, but I won’t get ahead of myself—the details are in the review.
Balancing connector with wires
14-07-2017, 23:04
This review is barely even a micro-review; it's more of a nano-review, it's so short. Still, I thought it might be useful to someone.
Good-quality holders for 18650 batteries
13-07-2017, 23:14
Another mini-review of various useful little things. This time, it’s holders for one or two 18650 batteries.
Frames for assembling battery packs from 18500/18650 cells
12-07-2017, 01:33
Today I have not just a mini review, but a micro review. It’s about some very inexpensive but useful “helpers” for anyone who often uses battery packs made from 18500, 18650, and similar cells.

EONE ET201, 2-in-1 multimeter, video review
2 8540
26-06-2017, 21:07
I decided to make a video version of my review of this unusual multimeter-oscilloscope, since some things are easier to show than explain in writing.
EONE ET201, a 2-in-1 multimeter, or how they crossed a snake with a hedgehog
25-06-2017, 01:48
Some time ago, I read a review of this multimeter, and recently I got exactly the same one. Since it was sent to me for testing, I had to write about it, so I’ll simply try to describe the device in my own words. Maybe someone will find something new here.
iLife A6 - Robot Vacuum Cleaner
24-06-2017, 15:20
Not long ago, I published a review of the iLife A4 vacuum cleaner. I also mentioned then that it was already an outdated model that had been sent to me by mistake, since the A4S had replaced it. This time, though, I'm reviewing a genuinely new model, albeit one in a slightly higher class: the iLife A6.
Expro x1 by IRULU, a small, modest tablet
6-06-2017, 16:34
Not long ago, I was asked to write a little review of an IRULU product. I decided to give it a try out of curiosity. A quick heads-up: this is a very basic tablet, but I’ll test it just like all the others. And of course, there’ll be a teardown.
Vernee Thor E smartphone, the Thor lineup continues
4-06-2017, 13:04
Almost exactly a year ago, I published a review of the debut model from a manufacturer that was still unknown at the time, Vernee. You can say a lot and criticize its shortcomings, but in any case, the Thor model they released first turned out not to be so bad after all, and one of these “firstborns” has been under my watch for more than a year now. So today I’ll tell you about the next phone in the Thor lineup, show it, and compare it with the previous model, sometimes “face to face.” And, of course, there’ll be the obligatory teardown.
