The abbreviation " VPN " has slowly become established among average Internet users, which is certainly good, but the problem is that people have started to see VPN as the ultimate solution to all problems.

Raspberry Pi - credit card sized computer

Raspberry Pi - credit card sized computer

The Raspberry Pi has gained great popularity as the smallest computer and is also popular among hackers, developers, and people involved in robotics.

It is the size of a credit card and has HDMI output, power input, processor, RAM, GPIO, camera input, 2.0 USB ports, etc. More below.

What makes this computer stand out - is the price. You can buy Raspberry Pi (model B and B +) for $ 35, ie. that's its price, and now it depends on where you buy. It costs over 5,000 dinars with us, and you can find it on foreign sites for around 30 euros. So, for 30 euros, you have a functional computer the size of a credit card with an incredible number of possibilities.

RPI model B+

Hacking, programming, robotics…

As I wrote at the beginning, this computer is also suitable for hackers because it runs Python scripts, is small enough to hide anywhere, does not consume much electricity, has everything a computer should have, and of course, works with Linux .

Developers and people involved in robotics also use this computer because it has GPIO (pins) that can be controlled by Python scripts. And so I can, for example, make functional, remotely controlled, robots.

The possibilities are really huge. People make web servers, media centers, smart devices… You can see some better projects at the end of this text.

Developers and people involved in robotics also use this computer

Model B and its more advanced brother Model B +

There is also a model A that no one buys anymore, model B is the most popular. But, the B + model has recently appeared, so now it is taking the lead. B + is a bit more advanced, has more GPIO, the layout of the inputs/outputs on the board has been slightly changed, microSD is used instead of SDcard, less electricity is used…

Add-ons make this computer even more powerful

As this is just a computer with several inputs/outputs, there are not many possibilities. The real power of this computer is given by the accessories that connect to it. Only 40 GPIOs (40 for model B + and 26 for model B) give this computer a lot of possibilities. You can also connect an LCD display, clock chip, camera… This computer comes with nothing, the computer itself in the box. But there is e.g. starter kit - packing with accessories to start with. It is mainly a case for Raspberry Pi, breadboard, various cables, heat sink, etc. Everything you need to get started.

Add-ons make this computer even more powerful

HDD? Where is the OS located?

This computer is so small that it makes no sense to put in an HDD because any HDD would be bigger than it. That's why he uses an SD card, ie. now MicroSD to host the system. I recommend 8GB class 10. Class 10 is more expensive but the speed is much higher, and as the card is used as an HDD, it is recommended to take it faster. The price is below 1,000 dinars.

What can I use this computer for?

Since it is powered by Linux, it can be used for anything: remote control, media center, home security monitoring, robotics, signaling, readings… On Youtube, there are video instructions for beginners, e.g. how to make LEDs blink, so for more advanced users. For starters, read all about this computer online, watch videos for beginners, come up with a project of your own, and buy a Raspberry Pi.

Where to buy Raspberry Pi?

I bought it on Aliexpress and it should arrive in 20 to 30 days (free shipping). I took it with some other supplements, so it cost me about 42 euros (about 5,000 dinars). With us, you can only find a computer, without any accessories, for a minimum of 5,500 dinars + delivery. If you want to go cheaper, read this article.

Samsung puts a camera under the screen - Notch is not needed!

By Administrator
Notch is the biggest flaw of smartphones today - period. For the vast majority of users, this is the main reason why they do not buy a phone, as well as for me. But Samsung has found a solution. True, Notch is only a transitional solution until companies find a way to place all the components on the front under the screen. Users demanded bigger and bigger screens, and smaller and smaller phones, so Notch was the only solution. Although it is present in many smartphones today, it is not generally accepted. Moreover, it is considered a flaw . Of course, the phone manufacturers told the story and tried to convince the users that Notch was ok, and many accepted that, and the others can't wait for that era to pass.

You probably download content from Torrent by first downloading the Torrent file and then running it in a Torrent client and the download begins. These Torrent files are useful because they are small and help to download gigabytes of content. Read more about how Torrent works HERE .
