Back in winter, news came out that RuiDeng was planning to release a new USB tester. I was particularly interested in this model, and now I have one in hand to test. This review covers the tests, as well as why this particular model caught my interest.

It’s no secret that television is gradually switching to digital broadcasting. Actually, no—it switched over a long time ago, and for at least the past 4 years they’ve been promising that they’ll “switch off” analog broadcasting any day now. But sooner or later, it will happen, and some owners of older TVs will be left, as they say, “up the creek without a paddle.” The TV itself will be like a suitcase without a handle: no use to you, but too good to throw away. But if you’re still happy with your old TV, you can add digital TV support with a small set-top box, which is what I’ll be talking about today.

I’ve already tested a TV box based on Amlogic’s new S905X2 SoC, and wasn’t entirely satisfied. Although it offered good performance and ran cool, it had a lot of software issues. Now I’ve finally got my hands on another model from the well-known Mecool brand, and today I’ll take a look at what it’s like and whether anything has changed. As always, I’ll inspect it, take it apart, run some tests, share my conclusions, and wrap up with a summary table.

This story began quite a while ago, around the middle of August, when I was writing a review of the Cubot Power phone. After publishing the review, I put the phone aside for a while, and a few days later I needed it to test how well it could scan barcodes. But then I suddenly discovered that the camera's autofocus had completely stopped working. That's what can happen sometimes when you take something apart. More after the jump.

This is my third review of TV boxes based on the Allwinner H6 system-on-chip (SoC). In my opinion, this processor is unfairly overlooked, with more attention given to models using Amlogic and Rockchip chips. Though the recently released models with newer Amlogic chips, made using a smaller process node, will probably draw even more attention. But let’s get on with the review: as always, I’ll take a look at the box, take it apart, run some tests, and wrap up with a summary table.

YR1035, another milliohm meter, an improved version of the YR1030
44 76414+7$56.00
I posted a review of the YR1030 milliohm meter. It’s a great instrument, and I use it very often—not just when working with batteries, but whenever I need to measure low resistance. I also have a friend who works with batteries, and a while ago I suggested he buy one too. He was a little skeptical, but after seeing it in action, he decided to get one for himself. Knowing the specifics of his work, though, I recommended the updated YR1035 instead of the YR1030. Today I’ll explain how they differ and why, in this case, the 1035 is the better choice.

Not long ago, I reviewed a hybrid TV box with tuners for satellite and terrestrial digital TV. At the time, someone pointed out that “there’s almost the same one, but cheaper,” so naturally I got interested and ordered it for review. So today’s review is of the “budget” version, without the satellite tuner, but unfortunately with a few other compromises as well.
