photo-booth

Raspberry Pi Photo booth (PiCamera v2)

running photo booth

(after setup and prep for auto launch, see sections below)

1. $booth
2. open new terminal window (Ctrl + Shift + N)
3. $opb

setup on rPi

1. begin setup on raspberry pi
2. add Apache and PHP $sudo apt-get install apache2 php7.0 php7.0-opcache
3. setup PHP to have default directory be ./www in this repo (see insturctions below: "Setup Default PHP Directory")
4. **** I'm sure something will go here too ****
5. $cd virtualenv && virtualenv -p python3 env --no-site-packages to prep all dependencies in project
6. start virtual environment $cd ../ && source virtualenv/env/bin/activate (see: http://sourabhbajaj.com/mac-setup/Python/virtualenv.html)
7. If setting up rPi, be ready to get some coffee. This next step takes a bit to install. (~15mins)
8. go fetch all python dependencies $pip install -r virtualenv/requirements.txt
9. setup picamera $sudo apt-get install python3-setuptools && easy_install3 --user picamera (see: https://media.readthedocs.org/pdf/picamera/release-0.8/picamera.pdf)

setup for running/editing/testing

See below about how to automate this

1. $cd wip/photo-booth/ && source virtualenv/envpi2/bin/activate
2. $cd www/ && php -S localhost:8000
3. open chrome with url: localhost:8000

setup default PHP directory

source: https://stackoverflow.com/a/23175981/3979495

1. edit apache2.conf file $sudo nano /etc/apache2/apache2.conf
2. edit <Directory /var/www/html> to be <Directory /home/pi/wip/photo-booth/www>
3. edit 000-default.conf file $sudo nano /etc/apache2/sites-avilable/000-default.conf
4. edit /var/www/html to be /home/pi/wip/photo-booth/www
5. restart apache $sudo service apache2 restart
6. open chrome and go to url: localhost

prepare the auto launch script on rPi

source: http://blog.startingelectronics.com/auto-start-a-desktop-application-on-the-rapberry-pi/

1. create bash alias: apb
2. $echo "alias apb='. /home/pi/wip/photo-booth/virtualenv/envpi2/bin/activate'" >> ~/.bashrc
3. create bash alias: opb
4. $echo "alias opb='chromium-browser --kiosk http://localhost'" >> ~/.bashrc
5. $echo "alias booth='apb && opb'" >> ~/.bashrc
6. Okay, now let's make it where terminal opens on boot and booth get called #magic
7. make directory for startup $mkdir -p .config/lxsession/LXDE-pi
8. edit startup $echo"@lxterminal" >> .config/lxsession/LXDE-pi/autostart
9. add booth alias to start on terminal load
10. $echo "booth" >> ~/.bashrc
11. now try a reboot

setup on mac for editing files on rPi

• find pi if needed: $sudo nmap -sP 10.10.1.1/24
• $ssh pi@10.10.1.199
• $sshfs pi@10.10.1.199:~/wip/photo-booth/ pi

helpful tips with setup

• connect mac to pi file system for editing (see: https://www.raspberrypi.org/documentation/remote-access/ssh/sshfs.md)
• stop virtual environment $deactivate
• freeze new dependencies while virtual environment is active (see setup #3) in virtualenv/env/ folder $pip freeze --local > ../requirements.txt
• camera interface settings will Disable if camera ribbon isn't plugged into port (Enable again and restart with camera plugged in)

To-Dos

• take picture
• overlay PNG onto pictures taken
• take 4 photos and make a gif
• collect user data into CSV, before taking photo
• store user data, photo file names, uuid, and if sent/emailed/shared
• create loop to start the next person
• validate data from user
• logic for if photoshoot.csv doesn't exist or camera module doesn't work
• add GUI (maybe Tkinter, appJar, or PyQt) (also see: http://appjar.info/ or https://github.com/cztomczak/cefpython)
• add visual countdown until camera captures photo
• add visual countdown for each photo being taken (when making a gif)
• resize images so gif is smaller in weight (see: http://picamera.readthedocs.io/en/release-1.10/api_camera.html#picamera.camera.PiCamera.capture)
• show resulting gif after gif created (start photobooth over after 10 seconds)
• send/batch social share and/or email the user a copy of photo/gif (see: https://www.raspberrypi.org/learning/tweeting-babbage/worksheet/)
• add overlay to preview (see: http://picamera.readthedocs.io/en/release-1.10/api_camera.html#picamera.camera.PiCamera.add_overlay)
• remove excess photos?? (9 total assets per instance)
• create slideshow of local ./camera-shots/
