I recently posted a review of LG HE2 batteries, but as I mentioned then, someone sent me a couple more batteries to test. Many thanks to him for that, since battery reviews are very useful.

One of my readers contacted me asking me to investigate and possibly help determine whether the batteries he received from Nkon were genuine. In this case, they were LG ICR18650-HE2 2500mAh batteries.

I've been using thermal imaging cameras for a long time. My first one was a very basic model with a resolution of 60x60. I later replaced it with an HT-A2 with a resolution of 320x240, and today I'm reviewing a model with a resolution of 256x192. It might look like a downgrade, but is it really?

Almost a year after this model came out, I finally got my hands on one. It was inevitable—I enjoy tinkering with this kind of thing. There are already tons of reviews of this model, so I decided to look at it as a measuring instrument and, more simply, check its measurement accuracy.

An interesting little device has landed in my hands: a clamp meter with 1 mA resolution and Bluetooth connectivity. As usual, I’ll take a look, run some tests, take it apart, and share my conclusions.

I needed a power supply for one of my new projects (among other things), so I decided to order a few different models to try out and test. Today, I’m reviewing the first one. A look inside, tests, and conclusions.
