With a small circuit with a bank card like a Raspberry Pi worth about $ 50, what can be done? If you bought a Raspyerry Pi and you don’t know what to do, let’s take a look at what you can do with it!

Where to buy Raspberry Pi?

If you have finished reading this article and want to try Raspberry Pi applications but don’t know where? Personally, I think you can buy it at the following 4 addresses: Mlab, Hshop, banlinhkien and RaspberryPi.vn or you can visit Number 84, Dai Co Viet, Hanoi or No. 71 Ngo Quyen – Ward 6 – District 10 – Ho Chi Minh City to be able to check directly!

Which version of Raspberry Pi should I buy?

In my opinion, if you use Raspberry Pi depending on your needs. The Raspberry Pi version I find most affordable is the Raspberry Pi 4 version B with 4 GB of ram, which is affordable for you, but the hardware is enough to use for powerful tasks. When choosing, you should choose SD memory card with high speed!

Things you can do with Raspberry Pi

Small PC

If you want to have a super small computer, the Raspberry pi will be a great choice. All you need besides raspberry pi is 1 monitor, 1 hdmi cord, keyboard and mouse and you have a great computer. With Raspbian operating system, you can use it to surf the web or use software on linux easily. In addition, Raspbian comes with LibreOffice – software similar to Microsoft Office and Chrominum so you can use it after installation.

you can refer to how to install Raspbian here

Wireless printer

Probably many of you here are using some kind of printer, but this printer does not have wireless printing function. Don’t worry, Raspberry Pi can turn into a device that receives data wirelessly and sends it to a printer. We can make it not only wireless, but we can also make it a cloud printer. You can set up a server and when the machine has a network connection, you can print it through the browser without having to be there.

Smart TV

If your TV is too old or you want to create your own smart TV, Raspberry pi can help you. By downloading Kodi to Raspberry and connecting to TV, you have a genuine Smart TV with tons of movies and entertainment channels. With the Raspberry Pi 4, you have so much more when the Pi4 is capable of delivering images with 4K 60fps resolution.

Create Minecraft Server

Between renting Hosting for Minecraft Server or buying Raspberry Pi and hosting my own minecraft server, I will choose to buy Raspberry pi. With the 4Gb ram version, you can host a server for 10 people to live together or play mid-sized mini games like bedwar or skywar without fear of lag. Not to mention with hosting as Pi, you will have a godly speed when if you are near wifi, the highest is probably 30ms.

What you need to do is install Ubuntu server for Raspberry Pi and follow the instructions here.

Create Webserver

If you want to create a cheap Webserver, Raspberry Pi is the optimal choice for you. you just need to install ubuntu server and install apache to be able to create a simple website. you can see more instructions to create Nextcloud here

Smart home

1 Smart home used to be the dream of many people but now, with raspberry pi, it has become simpler than ever. All you need is a little knowledge of python, a Raspberry Pi and a few tools needed to do it, and you can create a smart home.

Install Windows 11

With Windows 11, you will need a TMP 2.0 chip, but with Pi, you do not need to and can still install and experience Window 11 like on your computer. Since the chip running on the Pi is Arm, it will take you a bit of time to install it, but with a 4-core cpu and the version I’m using is 4GB of ram, it doesn’t make any difference to my computer.

That’s all I can do with Raspberry Pi. How about you? Leave a comment if you have an idea to use Pi!

I’m pretty sure many of you who follow Anonyviet sometimes have to encounter a lot of ads while surfing the web or playing free games. These ads are annoying to users and you would love to get rid of them. So if you have VPS or Raspberry Pi then Pi-Hole is your choice to do Adblock. Let’s find out with us!

What is AdBlock?

AdBlock is a software or Extension that allows them to remove or filter ads by changing the website structure and blocking traffic from advertising websites. Currently, Chrome Extension has tons of Adblockers such as ADblock, Poper Blocker and Stands Fair AdBlocker.

What is Pi-Hole?

Pi-hole is a tool that turns Linux into a DNS Server used to block ads that work on the entire home network. You don’t need to install adblock or extensions in the Chrome store and you can whitlist some Adblocks. Pi-holes are extremely useful even with devices that you cannot interfere with to block ads, like Smart TVs or Smart watches.

When you type the name of a website and press Enter, the computer will give that website to the Pi-Hole server via DNS. Pi-Hole will start looking for that page to run in the browser and it will also start checking the ad pages that will run with the website to block. And finally, no matter what website, Pi-Hole will remove ads.

Why Pi-Hole and Benefits of Pi-Hole

According to official information from Chrome, all Extensions built on the Manifest V2 extension license management system will no longer appear on the Chrome Web Store as of January 17, 2022 and will be completely disabled on January 17, 2022. January 2023. This invisibly turned all Adblock Extensions disabled by 2022.

At the same time, Pi-Hole also has some of the following benefits:

• Easy to install with just a few commands
• Block ads on any device, any application (including devices that do not allow adblock installation)
• High speed, light
• Easy control thanks to the graphical user interface using the browser
• Can block both IPv4 and IPv6 of advertising sites
• Totally free

Instructions for installing Pi-Hole to block ads

So from now on you can freely surf the web without fear of ads. If you have any trouble, please leave a comment below so I can help!

Currently, Vietnam fiber optic cable is having problems due to broken cable and so it makes it difficult to access a website with foreign servers and if you want to create a blog or want to host a game server, buy raspberry. pi is the best choice today with cheap price and extremely small hardware, but the problem in Vietnam is that the IP address is not a fixed IP address, so when we point the DNS back, it will be 1 time later. have to check the ip and point again. This problem is time consuming and if you are not at home accessing the raspberry pi is almost impossible. And so, DDNS was born and today I will guide DDNS on Raspberry Pi with Cloudflare API.

What is DDNS?

Dynamic DNS, Dynamic Domain Name System or DDNS is a method of automatically updating name servers in the Domain Name System, usually in real time, with active DDNS configuration of hostnames, addresses, or other information. configure it. DDNS was created to replace static IP addresses. It helps users to access the system remotely without using the static IP address generated by the ISP (Internet Service Provider – Internet Service Provider).

Each domain name will have to point to a static IP (static IP), but the network addresses provided by the network operators in Vietnam and some other countries are usually dynamic IP (dynamic IP) and they will be changed accordingly. 1 certain period. In case you want to point DNS to that IP, it is not possible. That’s why DDNS is put into practice.

The way DDNS works is extremely simple. DDNS creates a special program that runs on the user’s computer called a Dynamic DNS Client. This program is responsible for monitoring and checking the change of IP address at the server (host). When a change occurs, Dynamic DNS Client will notify the DNS system. At the same time update new information to the previous database. Even if the server frequently changes its IP address, the DNS system can still find and point the domain name address to the correct new IP address.

Usually DDNS is often used for webserver hosting services, home game server hosting, using IoT devices or installing security devices to protect your home through your wifi NAT port. At that point, your devices will use the public IP to be able to access it, but as mentioned, this IP address is not a static IP address.

Requires supplies to perform

• 1 Computer running Linux and capable of being maintained 24/7 and connected to your home network. Recommended to use Raspberry Pi because its hardware is capable of running 24/24
• 1 domain name is not a Free domain (domain names ending in .tk, .ml, .ga, .cf, .gq)
• 1 account CloudFlare

Instructions for making DDNS client on Raspberry Pi

Basic set up

After creating a CloudFlare account, please read the article Create a free domain for 1 year with the latest Freenom and go to the DNS pointing section to point DNS to your home network!

I will use Raspberry Pi 4 4GB ram to run

Step 1: After pointing the DNS, go to the terminal and write the following command:

git clone https://github.com/K0p1-Git/cloudflare-ddns-updater.git

Step 2: Enter that directory with the command

cd cloudflare-ddns-updater

Step 3: You rename the file by

mv cloudflare-template.sh cloudflare.sh

From this paragraph onwards, the file I will use under the file name I just set. If you put it differently, remember to rename it in the command!

Step 4: You guys Edit files Cloudflare.sh

sudo nano Cloudflare.sh

Step 5: Replace the following information in the file

Note: replace the quotation marks

• auth_email: enter the email you registered with Cloudflare
• Auth_key: Enter API token (See how to get API token and Zone ID below)
• Zone_identifier: Enter Zone Identifier (In the How to get API token and Zone ID section below)
• Record_name: enter your record name. it will take the form tenrecord.tenmiencuaban.
  Eg: website.anonyviet.com

Step 6: Press the key combination Ctrl + x > bấm y > press enter to save the file again

Get API and Token Zone

Step 1: Go to page https://dash.cloudflare.com/

Step 2: Select your domain name

Step 3: Scroll down and you will see Zone ID In the API section. Take it and copy it to your SH file

Step 4: Go to Get Your API token

Step 5: In the Global API key section, click view. After doing the capcha, you take that key and copy it in as step 5 of the basic setup item

Setup time to run the script

Step 1: Go to Terminal and type

Crontab -e

Step 2: You choose your editor. Choose which one, write down its number!

Step 3: You write the following command

* * * * * /bin/bash [vị trí file Cloudflare.sh]

The asterisks are equivalent to 1 date and time unit and you just need to change the asterisk to a number. Their order is: minute > hour > day > month > day of the week (Monday to Sunday)

Step 4: Press the key combination Ctrl + x > bấm y > press enter to save the file again.

Step 5: Run the following command to boot

systemctl restart cron

After setting up the Raspberry Pi, you may not need to attach additional monitors to it. When maintenance tasks are needed, such as upgrades and reboots, you can use Secure Shell (SSH) instead of plugging in your computer. So in this article, I will show you how to SSH into Raspberry Pi.

What is SSH?

SSH stands for Secure Shell. It allows you to remotely connect to a server or system from another device using encrypted communications.

The main benefit of SSH is data encryption. With less secure remote login protocols, such as FTP, everything is sent in plain text. A hacker could uncover those communications and record things like usernames and passwords. Since SSH is encrypted, hackers won’t be able to do so anymore.

Security issues before enabling SSH

Enabling SSH is easy, but you should also take care of a few issues. First, make sure that your Raspberry Pi is secure. By setting a password for the user account.

When you first set up your Raspberry Pi, you should change the user account password. If you haven’t changed your password, you need to do it now. Open terminal, then enter passwd command.

passwd

You will be prompted to enter your current password, then choose a new password.

View the IP address or hostname of the Raspberry Pi

You will also need to know the hostname or IP address of the Pi. Enter the following command in the terminal:

hostname -i

This command will provide the IP address for your Raspberry Pi. That address will usually start with 192.168. Record the address or hostname.

Next, we will enable SSH.

Method 1: Enable SSH via GUI

One way to enable SSH is through the Raspberry Pi graphical interface. Just click the Raspberry icon in the top left corner of the screen, then click “Preferences” and select “Raspberry Pi Configuration”.

In this app, click on the “Interfaces” tab and look for “SSH”. Click “Enable”, then click “OK” to close the application.

Method 2: Enable SSH from Terminal

Another method to enable SSH is from the terminal. Enter this command to enable the configuration tool for your Raspberry Pi:

sudo raspi-config

Use the arrow keys on your keyboard to select “Interfacing Options”, then press the Enter key.

Select “P2 SSH” and press Enter.

When asked, “Would you like the SSH server enabled”, select “Yes”. Press Enter again at the confirmation box, “The SSH server is enabled”, select “Finish”.

Disable SSH Root login

After you’ve enabled SSH, there’s another optional thing you should do. Letting the root user SSH into your Raspberry Pi is a security risk, so I recommend disabling root login via SSH. Remember that you can always issue administrative commands from your regular user with sudo.

In your Terminal window, enter this command:

nano /etc/ssh/sshd_config

Now look for this line:

#PermitRootLogin prohibit-password

Edit this line to:

PermitRootLogin no

Save and close the file by pressing Ctrl + X, then Y. Now you should restart the SSH server with this command:

/etc/init.d/sshd restart

There are other steps you can take to SSH server security more, so make sure your Raspberry Pi can take the risk.

Login to your Raspberry Pi from another computer

Once those steps are complete, you’re ready to log into your Raspberry Pi from any computer on the local network. With the IP address or hostname you wrote down earlier, you can ssh into your Pi with the following command

ssh pi@[address]

For example, if your Raspberry Pi’s address is 192.168.0.200, the command would be:

ssh pi@192.168.0.200

The first time you access your Pi, you will be asked to accept the encryption key. Just press Y, you’ll connect and be prompted for your password. Once done, you will be logged into the Raspberry Pi and can perform any task you need.

In addition to giving remote commands, you can also use SSH for other purposes, such as tunneling traffic, transferring files, connecting remote file systems, etc. In addition, you can also block ads with Raspberry Pi here.

Raspberry is increasingly becoming more and more powerful, if only with a range of 1 million – 4 million you own a small PC and install hundreds of things on it. Normally we will use the Raspberry Pi operating system to use, but there are also 22 operating systems you can install on Raspberry to exploit its full features. In this article, I will list 22 Operating Systems that can be installed on Raspberry Pi for your reference.

Best Raspberry Pi powered OS

first. Raspbian

Introduced by the Raspberry Pi Foundation, Raspbian will be the first operating system in the Raspberry Pi research process. Raspbian is packed full of tools and features to make the most out of your PCB (printed computer board). It is also a great introduction to Linux.
