I built a minimalist PC recently. I used the “Raspberry Pi 3” as the CPU here. It has a quad core ARM processor and 1 GB RAM. Hence, it can run a Linux operating system very well. I recommend this PC for day to day use at home and also for small businesses.
Here are the things that I bought.
- 18.5 inches HDMI monitor – Micromax 18.5-inch LED Monitor(MM185HHDM1P3) With VGA Plus HDMI (Black )
- Raspberry pi 3 – Raspberry Pi Model B RASP-PI-3 Motherboard
- Micro SD Card 16 GB or more – SanDisk Ultra MicroSDHC 16GB UHS-I Class 10 Memory Card (SDSQUNB-016G-GN3MN)
- 2 Amp mobile charger – something like WireZone Samsung Fast Charger 2.0Amp – For Samsung Galaxy S6 J1 ACE J2 J3 J2 PRO J5 J7 Note 2 Note 3 Note 4 E5 E7 On7 On5 On NXT A5 A7
- USB Keyboard and Mouse – Zebronics JUDWAA 560 Multimedia USB Keyboard & USB Mouse Combo
- HDMI cable – WireSwipeTM HDMI Male to HDMI Male Cable TV Lead 1.4V High Speed Ethernet 3D Full HD 1080p (1.4 meter)
Preparing the Operating System on the micro SD card –
Using an existing PC, I did the following –
- Download the Raspbian Operating System image for raspberry pi.
- Navigate to Downloads on raspberrypi.org and then select “Raspbian”.
- On the next page, download the zip file corresponding to “Raspbian with PIXEL – Image with PIXEL desktop based on Debian”.
- Download and install the Etcher software on your existing PC.
- Write the image to micro SD card
- Place the micro SD card on a card reader and plug it to your PC.
- Run Etcher.
- Click on the “select image” option.
- The storage device should be auto populated with the micro SD card location. If not, select it manually.
- Click on Flash and wait for the process to complete.
- Now, the micro SD card has the operating system required for the new PC. Remove the micro SD card.
Putting it together –
- Insert the prepared micro SD card in the appropriate slot on the Raspberry pi 3.
- Plug the 2 Amp Charger to the Raspberry pi.
- Plug one end of the HDMI cable to raspberry pi and the other end to the Monitor.
- Plug the USB Keyboard and Mouse to the USB slots on the Raspberry pi.
- Power on the monitor and the Raspberry pi.
