50 Buck's full Arch Linux Computer on a Pi

• Introduction Video
• Install Arch Linux in a Rapberryp Pi Zero 2W

This €50 beast is the ultimate playground for mastering Linux. Installing a legendary distro like Arch Linux on it is basically the digital version of a black belt initiation. Think about it: if you can get it purring on a Pi Zero 2, you can pretty much run it on a smart toaster or a vintage calculator. If it has a heartbeat, it can run Arch Linux ! ;)

Create system for first boot video 1 - First Boot

Create partions

Using fdisk, create two partitions in the Micro SD

• 1 - Create first primary partition, with 1Gbyte and fat 32, for boot;
• 2 - Create second primary partition, with the rest of the space in ext4, for root.

Format partitions

• 1 - Format first partition with ** makefs.vfat /dev/"first partition" **;
• 2 - Format second partion with ** makefs.ext4 /dev/"second aprtiton" **.

Download system from Arch Linux Arm

• wget http://os.archlinuxarm.org/os/ArchLinuxARM-rpi-aarch64-latest.tar.gz

Create Systen to boot

• 1 - Create a folder with two subfolders root and boot; ...bash mkdir -p rpi_project/{root,boot} ...
• 2 - Mount frst partition in boot and second in root;
• 3 - Move your tar file to the root folder;
• 3 - Extract the tar file and delete the tar (you dont need it anymore);
• 4 - Move all files from root/boot to the boot;
• 5 - Correct the fstab to mount the /boot (first partition) and / (second partition);
• 6 - unmout ./boot and ./root;

First Boot video 2 - Configs

Enter with root user. For Arch linux ARM the password is root.

• 1 - Get rid of the bug with the Broadcom WIFI with wpa_supplicant

echo "options brcmfmac feature_disable=0x82000" > /etc/modprobe.d/brcmfmac.conf
reboot

• 2 - Create a autentication config file for the wpa_supplicant

wpa_passphrase "your SSID" "your password" > /etc/wpa_supplicant/wpa_supplicant.conf

• 3 - Connect the WIFI and get an IP from router

wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf
dhcpcd

• 4 - Update keys of Arch Linux Arm

pacman-key --init
pacman-key --populate archlinuxarm

• 5 - Update and upgrade the system and install some apps

pacman -Syu htop fastfetch vim

General configs and regional settings video 3 - Remote general configs

Now we area going to make the 50 bucks pc start with all correct stuff

• 1 - Start your network every time in the init system in Arch Linux the systemd

cd /etc/wpa_supplicant/
mv wpa_supplicant.conf wpa_supplicant-wlan0.conf
systemctl enable wpa_supplicant@wlan0.service
systemcrl enable dhcpcd

• 2 - Set local time the example is for Azores and Portuguese

ln -sf /usr/share/zoneinfo/Atlantic/Azores /etc/localtime
timedatectl
echo pt_PT.UTF-8 UTF-8 > /etc/locale.gen
locale-gen
echo LANG=pt_PT.UTF-8 > /etc/locale.conf
echo KEYMAP=pt-latin1 > /etc/vconsole.conf
localectl

• 3 - Some more tweaks and software

Edit with su the /etc/pacman.conf and uncoment #Color and add ILoveCandy ( ;) ) Install basic tools to build Arch Linux packages and sudo as dependency

pacman -S base-devel

Uncoment the group wheel in the file /etc/sudoers exit from su, now you can use sudo

sudo pacman -S git river-classic fuzzel foot

Clone my configs

git clone https://github.com/dpnpinto/PintoRpi

A light graphical enviroment for RaspberryPi Zero 2 video 4 - GUI config

cd PintoRpi
bash install.sh

A nice ZX Spectrum emulator for the 50 buck's PC Video of how to do

For me, the ZX Spectrum 48K was the absolute GOAT (Greatest Of All Time). It was my very first computer—a literal magic box that let me bend code to my will!

Fast forward to today: I've got this $50 micro-computer that was clearly inspired by the Spectrum’s 'affordable-but-scrappy' soul. It might be cheap, but it's got potential. Time to fire up a killer emulator and relive the glory days!

So in honnor to my son and the good old times:

• Spectrum Emulator from Sergio Costas Rodriguez repository - fbzx
• 50 buck's PC with Arch Linux ;)
• Games used for testing from https://worldofspectrum.net
• Buy a ZX Spectrum from Amazon and support my work
