How check with devices powered batteries

Batteries are always present in our lives. From watches to cars with remote or flash, they all need energy, we withdraw from the mundane batteries.
The problem occurs when we have so many batteries around the house that I do not know which is loaded and discharged.
Meter is a tool that helps us to see how the battery is loaded. Unfortunately, not everyone has the multimeter or not everyone cares to look for it / use it, just to check the batteries.
Fastest method for detecting the discharged battery, consists of "tapping them on the table" and observe the reaction. This method of checking battery actually works, and not some figment.

How check discharged batteries?
Draptă on a surface, solid and stable, from 5 cm, the battery easily escape in a controlled manner. If the battery jumps easily, it is discarded or used for a longer period. The batteries charged, not conduct it, they are hit easy meal. Charging the batteries, if they stick to the table, do not jump at all.
Interesting observation!
If you use this method to check the batteries downloaded more time, you will realize that batteries are discharged than others; Because not all jump as batteries.
It may be something in battery to power, but insufficient for serious electronics.
How does the method to check the batteries?
Batteries are made up of three main components, among others. We anode, cathode and electrolyte, which in the case of alkaline batteries, is a base (alkaline) the consistency of a gel. When the battery is used, the chemical reaction occurs that produces current. The chemical reaction that transforms the electrolyte, the gel into a solid mass, crystallized. Therefore batteries or near consumed, are jumping.

  2. Hello. A linux videotutorial with installation and personal mail server setup can? I have a web server and keep a "www.nume.ro" page. Now I would like to have my own personal mail "[Email protected]". I do not have confidence in hosting free or paid ... if I still have a linux server cares about me.
    if you do not have time or have other reasons a more explicit guidance on how a beginner in internet mail servers on Linux? I searched I give I give commas. Saying no one from head to tail exactly how.

    • My advice would be to pay for hosting. Find and 1 dollar a month, and you'll have plenty of tools at your disposal.
      The server kept home is the worst idea. First you'll have non stop noise. Net providers do not really agree with servers at home, and sometimes block the ports 25, 21, 22. Current'll consume more than 1 dollar per month. Problems will arise in time, they will waste energy and will keep you in business.
      Email server kept at home can be seen as a source of spam; And if that happens, your server will become useless.
      Seriously; I do not recommend!

      • Cristi yes I know, you're right. I found the 6 euros / month hosting full options. I would like to know how to do a mail server on Linux and thought are not the only one who wants. 25 port was closed to unlock request that I made and I locked myself in the server do not spam greasela until something concrete to manage mail server. There are many companies that linux server with: web server, mail, ftp ... .. not think it's very difficult to give still have not found concrete information.

        • Hello
          I hope to be helpful.
          Server you can do at home quite simple, if you already nume.domeniu, I guess you already solved dynamic DNS so nume.ro always point to your dynamic IP.
          To make a server, search for a tutorial on installation: Postfix + Dovecot + SpamAssassin + clamav + mysql (optional, but it's easier to progestins users) is a pretty good combination. Owning something for years, go smoothly.

          • Hello . thank you for the advice . I managed it. But sending mail reaches its destination yes no going backwards. I can not receive mail. Even with spam. I think there's something to set ROTLD or my dns server. I do not know…

I hope you are comfortable with the idea of ​​forum and especially to be feasible. All the best.
