If you are looking for a low budget computer for small official work or online study purposes then this article will be very helpful for you.

It is a slightly different concept of commuter. In regular tower pc, we can install Ram, Hard drive, different cards etc. those computers consume about 250 watts of power.

Besides the SBC ( single board computer ) has onboard Ram, its Os runs from a micro SD card & its power consumption is very small. It can run using a 5-volt smartphone charger.
So we can confidently tell it, The single-board computer will be taking a valuable role in the future of computing.

In this article, I am going to describe, how you can make a very low budget desktop computer using Raspberry Pi.

Raspberry pi is a popular single-board computer.
Raspberry pi OS & software are open-source. so no need to buy softwares.

What works can be done using Raspberry pi 4 Desktop

At first, I want to tell you that what works can you do with it & whatnot.
I am also going to discuss about gaming on Raspberry Pi.

So you can easily decide whether is it really useful for your work or not.

Then insert raspberry pi board in the case

Raspberry pi 4 Fan installation

The fan is running on 5volt dc. We have to connect fan + (Red wire to GPIO 2) & fan negative – (Black wire to GPIO 6)

Watch the video for fan installation & connection

Pi 4 monitor connection

Connect monitor, mouse & keyboard,
Audio speaker. now the hardware part is ready.

Raspberry pi OS download & installation on SD card

We have to burn the operating system for raspberry pi on an sd card.
For burning os, we have to use a windows pc. It needs only for the first time, after that no need any other pc support.

Video tutorial for making Raspberry pi 4 desktop

Open your windows pc.
We have to download a free software for windows.

raspberry pi imager download

Download raspberry imager software for windows from here. You can download it also for mac & Linux.

Now download the latest version of the raspberry pi desktop image from here. It is the operating system of pi & it is free.

Download Raspberry pi os with desktop & recommend software.
Its size is near about 3….GB.

Now install the raspberry pi imager software on your PC. unzip the pi os zip file. When Unzip is done, here you can see the image file. Its size is about 8 GB.

Insert your Sd card using a card reader.

Make sure your card has not any important files otherwise all fills will be deleted from the sd card after image burning.

Open raspberry pi imager.

Choose Os – Now go to Use custom
Now select the image file which is unzipped – Click on open.

Now chose storage
Select sd card.
Here please be careful that you are choosing the right sd card.
Now click on write.

It takes some time when it is completed, click on continue.

Now insert the sd card on Raspberry Pi. Connect power & it is ready for work.

Now our raspberry pi desktop is ready for work.
You can install additional software using the command terminal.

Here we are discussed only for making a desktop computer using raspberry pi but raspberry pi can be used in also different types of projects.
It has GPIO pins like a microcontroller so we can do many more creative projects
By using some sensor with it.
