Raspberry Pi preparation

1. Download and install Raspbian Jessie lite.
2. Plug in your Raspberry Pi, provide a screen, network and a keyboard, and let it boot.
3. Prepare the system environment:

• Log in with user & password: pi / raspberry. Become super user: sudo -i

• Update the installed packages (including raspy-config) by typing apt-get update && apt-get upgrade

• Edit file /boot/config.txt, and add the following lines:

  `framebuffer_depth=32`  
  `framebuffer_ignore_alpha=1`
  

• Install some more needed packages by typing

  apt-get install python-picamera python-pygame python-pip python-imaging xorg cups cups-bsd git

• Optional: install more standard tools:

  apt-get install htop iotop vnstat vim-nox

• Change hostname to photobooth

  echo photobooth > /etc/hostname

• Add a new local user, make up a safe password.

  adduser photobooth

• Grant camera access for the newly created user

  usermod -a -G video photobooth

• Install the printer (I can't tell you how right now, because this is a mess)

• Start raspi-config

  • Choose Expand Filesystem
  • then select Enable camera and hit Enter
  • Go to Finish and choose to reboot.

user autologin and app autostart

1. Install application and dependencies from github repository

• log in as photobooth
• Check out software into local folder: git clone https://github.com/maduck/photobooth.git

1. Set up automatic login and program start

• create file /etc/systemd/system/getty@tty1.service.d/autologin.conf, with the following content:

   `[Service]`  
   `ExecStart=`  
   `ExecStart=-/sbin/agetty --autologin "photobooth" %I`
  

1. Let the graphical user interface / X server automatically start on login:

   echo startx >/home/photobooth/.bash_profile

2. Change the file owner to our photobooth user:

   chown photobooth.photobooth /home/photobooth/.bash_profile

3. Create a script for executing the photobooth app, named /home/photobooth/start_app.sh, with the following content:

   sleep 5
# disable screensaver
xset s off
# disable energy saving
xset -dpms
# start photobooth app
python photobooth/booth_app.py

4. Change the ownership of this script, and make it executable:

   chown photobooth.photobooth /home/photobooth/start_app.sh
chmod u+x /home/photobooth/start_app

5. Let the xorg server automatically start the app script:

   echo ~/start_app.sh >/home/photobooth/.xinitrc

6. update your /home/photobooth/photobooth/settings.cfg, if needed.
