It is well known by now that iPhones are not particularly known for the hardness of their screens, that's why today we are going to talk about it. ComoHacer.eu let's see how to replace the broken screen of an iPhone 4The process is explained step by step and in detail so that there is no doubt about the process.

First of all and before we start, we have to be clear that even if the screen of your iPhone is still working, it must be replaced as it is impossible to detach the screen (or LCD) from the glass (or digitizer), therefore we must be very careful what we buy.If you don't want to take the risk, buy the screen that we have already tested, which includes both the screen and the glass.

How to make a mixed charge regulator (solar panel and wind turbine)

For quite some time now, in ComoHacer.eu we are promoting renewable energies and the responsible use and reuse of materials, as an example of this we have the tutorial that we translated from the great Michael Davis on how to make a photovoltaic solar panel and a homemade wind turbine, in which, in the latter case, we add the design and manufacturing of a charge regulator or charge controller. Over time Mike discovered a new, much more efficient and cheaper design to do this and today we bring it here for you to enjoy.

As the cover of this article we have a simple diagram of the layout of a complete renewable energy system to obtain electricity from the wind and the sun. As we can see, the charge regulator plays a key role in this system, and not for nothing, as it is in charge of telling when the batteries should be charged and when the electricity generated should be dumped into the dummy load so as not to damage them. Let's see what we need to make our charge regulator:

10 tips to protect your Wifi

Leave a Comment / Internet / By Alberto Navarro / 8 minutes of reading

Wifi connections are becoming more and more common, there is no place in any medium-sized city where you can scan with your mobile phone and not find any network within reach, and many of them insecure or with easily decipherable encryption. We already saw a few weeks ago how relatively easy it was to hack any type of wifi, from the already famous WEP, to even WPA/WPA2 thanks to the WPS protocol or default keys, in the best of cases, it takes mere seconds in obtaining a Wifi key.

Since the other day we showed you how to hack your own Wifi, today I feel morally obliged to give you all the tips you need to make your secure Wifi connection. Thanks to the previous article I have been able to learn to distinguish the weak points of our Wifi connections and thus compile them in the following article. The order used is by importance, although it is very relative as it is totally my choice according to my experience, here we go:

Hacking Wifi to get your own key (part 2 and end)

2 Comments / Internet / By Alberto Navarro / 10 minutes of reading

We have already seen in the first part of this tutorial the ways we have of hacking our own wifi keys through a distribution prepared for it, in this one we are going to go a step further by explaining the possibilities we have to do it from other systems apart from Linux, which although we know that it is the best for this task, is not the only one.

Seeing how many people use Windows as their main operating system, we're going to start there by looking at all the options we have, but we'll also go through the operating systems Android, iPhone, Windows Phone, Blackberry and even online tools to retrieve wifi passwords.

Homemade Wifi and DVB-T antenna from an old UHF antenna

Note: If you are looking for a high gain Wifi antenna or a DVB-T antenna for your PC, you can look in our shop as we have these products at the best price.

Rummaging through my garage junk I found an old UHF antenna that had no other destination than to go to the clean point of my city. Obviously I quickly saw the potential that this antenna could have and I started to test and investigate a bit, firstly I checked that the antenna (which is actually two independent ones), was fully capable of picking up the current DTT signal and send it to a tuner to be able to watch TV without any problem.

As the rear antenna picked up enough signal to not need the front antenna, I was looking for a way to use it as well, and I thought of adapting it to be used as an antenna. homemade Wifi antenna. I got myself a cheap Wifi antenna (we have it in our official shop) that would serve me for that purpose (to experiment a bit), and a USB cable so that it would be totally Plug and Play. I was looking for something that, first of all, was cheap, so that if it broke down it wouldn't hurt too much, and that had an external antenna, so that I could open it and splice the cable of the Wifi antenna with that of the old UHF antenna.
