DIY Raspberry Pi NAS: A Practical Guide

To not miss my updates, remember to check the public account in the upper right corner and mark it as a star, drop a star for me.

Is your idle Raspberry Pi collecting dust? Today, I will teach you how to build a NAS device using Raspberry Pi.

NAS devices on the market are generally expensive. If you have a Raspberry Pi on hand, it is very economical for engineers to DIY one.

When DIYing a device, the shell design can be based on your preferences:

Only the power and network connectors can be accessed externally.
Both connectors are located on the back and are adjacent to each other.
Avoid a 90-degree offset of the power and network connectors, which is a typical feature of Raspberry Pi.
USB connectors and cables must all be inside the shell to ensure a clean design.
Meaningful multi-line LED display instead of simple status LEDs, and the brightness at night will be reduced.
The components used must be inexpensive and easy to obtain.

Therefore, the process of making this NAS device not only requires some manual skills but also involves 3D printing shell parts, soldering techniques, and software configuration.

Step 1: Preparation Raspberry Pi

Install the Raspberry Pi OS image, the easiest way to install the operating system (Pi OS) on Raspberry Pi is to use Raspberry Pi Imager. You can download it here: https://www.raspberrypi.com/software/

Raspberry Pi Imager is very user-friendly:

– Insert the micro SD card into the computer.

– Launch Raspberry Pi Imager.

– Select the Raspberry Pi model.

– Choose the operating system -> Select “Raspberry Pi OS (other)” -> Select “Raspberry Pi OS Lite (64-bit)”.

– In “Select Storage”, choose your micro SD storage card.

– Click “Next” and follow the further instructions.

After the imaging process is completed successfully, insert the SD card into the SD card slot of the Raspberry Pi. Then connect the power cable and network cable to the Raspberry Pi and wait for it to boot up.After a few minutes, check the router to see the IP address assigned to the Raspberry Pi.Now, you can log in to the Raspberry Pi via SSH.

For detailed steps on assigning static IP addresses, network name resolution, and installing updates and other packages, refer to the original text: https://www.instructables.com/Raspberry-Pi-NAS/

Step 2: Print the cabinet parts and install

The NAS case consists of only four parts, which can be printed according to the 3D source files shared by the author.

After printing the shell, use M2.5 brass screws and nuts to install the Raspberry Pi and hard drive.

At the same time, connect the external power interface and LED screen, and connect the screen and Raspberry Pi through ribbon cables. The operational steps will not be detailed here. The final product:

Step 3: Install OLED software

In the attached program oledinfo.py, different screens will be displayed on the OLED screen, which contains useful information about the NAS. The screen changes every 10 seconds in a loop. The brightness of the display will be reduced from 10 PM to 7 AM. Since this program is Python code, it can be easily modified according to your needs.

Step 4: Install NAS software Openmediavault

Once the hardware is ready to run, the most important point is: NAS software.

Of course, you can install any NAS software you like. Below, the installation of openmediavault is described, as it is easy to execute and the web-based user interface makes it easy to manage.

Installing openmediavault is very simple. To install the openmediavault software, log in to the Raspberry Pi via SSH and run the command:

sudo wget -O - https://github.com/OpenMediaVault-Plugin-Developers/installScript/raw/master/install | sudo bash

After installation is complete, launch a browser on your computer and go to:

http://192.168.1.4

(Use your own IP address)

Important: Use the http:// prefix, as the HTTPS protocol is not enabled by default. You can enable HTTPS later.

The openmediavault login page should appear in the browser, and you can log in to the openmediavault instance using the following credentials:

User: admin

Password: openmediavault

Now, you can start configuring the NAS.
