DIY photo booth

Preparation

1. Download and install Raspbian Jessie lite.
2. Plug in your Raspberry Pi, provide a HDMI 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 adduser photobooth, make up a safe password.
   • 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.
4. 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

5. 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

   • Create file /home/photobooth/.bash_profile, with the following content:

     startx

   • Change the file owner to our photobooth user:

     chown photobooth.photobooth /home/photobooth/.bash_profile

   • 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/app.py

   • 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.sh

   • Create the Xorg autostart file /home/photobooth/.xinitrc, containing just the line

     ~/start_app.sh

6. That's it! Enjoy your cool system!
