Electronics and technology blog    /    Materials for July 2022 year

Some time ago, one of my readers got in touch and offered to let me test their new product, which had recently gone into production. And what can I say? I'm interested in all kinds of hardware, especially when it's smart. As always, I'll take a look, take it apart, run some tests, and share my conclusions.

Not long ago, one of my readers decided to buy batteries to replace the ones in his angle grinder battery pack. I was interested too, so I tagged along and ordered one to test.

A while ago, I posted a preview of my solar power station build on Instagram. Well, not only is it now installed, it’s also been generating power for three weeks. I’ve finally got around to writing up how I built it.

This isn’t a review, or even just a test. I’ve come across some unusual rulers (at least in my opinion), and today I’d like to show them to you. Maybe some of you have even used rulers like these.

A friend of mine had a manual sprayer, and we got the idea of converting it to battery power. Read this mini-review to see how it turned out.

Another measuring instrument. It’s not quite as original as the previous one, and it was made in a specialized factory, but I liked it all the same.

Today I’m reviewing a rather unusual measuring instrument. I saw it at a friend’s place and couldn’t resist showing it to you. I hope you find it interesting.
