crpalmer/pi-setup

Make sure you have the rpi-imager installed:

sudo snap install rpi-imager

Run the rpi-imager with the sd card inserted and install the Lite Raspberry Pi
OS to it.  When setting up the install, enter a hostname, username / password,
wifi credentials, enable SSH, etc.

Insert the sdcard and boot up the pi with ethernet attached (if possible)
and then:

If you have reusing a hostname that is already known clear the keys:

ssh-keygen -f "/home/crpalmer/.ssh/known_hosts" -R HOSTNAME

and then ssh to the machine.

sudo raspi-config
  * Advanced Options >> Expand filesystem [probably not needed anymore]
  * Localization Options >> Change Locale to en_US.UTF-8 UTF-8 and use it as default

Don't bother restarting and instead update the software:

sudo su -
apt-get update && apt-get -y upgrade && apt-get -y install git && apt autoremove -y

Restart and login again.

sudo su -
git clone https://github.com/crpalmer/pi-setup.git setup
cd setup
./initial-setup-generic.sh

If you want to add the halloween autorun script run:

./setup-autorun.sh

vi .git/config
  change origin to git@github.com:crpalmer/pi-setup

exit to get back to crpalmer:

git clone git@github.com:crpalmer/pi_lib.git lib
(cd lib && make)

Change /etc/dhcpcd.conf and update the network device to make static like:

interface eth0
static ip_address=192.168.1.6
static routers=192.168.1.1
static domain_name_servers=192.168.1.1


==== Temperature Sensors on 1wire ======

sudo raspi-config
 * interfacing Options >> 1 Wire Interface >> Yes

and reboot

You should now see devices in /sys/bus/w1/devices that correspond to the device id and also a w1_bus_master1 device.


==== Kiosk Mode ====

sudo apt-get install lxde lightdm xinit
sudo apt-get install chromium-browser x11-xserver-utils
