Photo-Booth

This is a simple photo booth application that allows users to take pictures through a web interface on a gphoto2 compatible camera (I'm using a6400), and then send the pictures to an email address.

Note: This is some what of a work in progress, I was planning to use it at a Hackathon but I kept getting segfaults from the gphoto2 bindings.

Another note is that there is some "security" built into this application like the option to use https and a password to access the backend, but I wouldn't trust this too much.

Getting Started

There's two main components to this project, the website and the backend which controls the camera.

Website

First you'll need to create frontend/.env based on the frontend/.env-template file. Here's a little more about each of the variables.

  • PUBLIC_APP_PASSWORD - This is a password specified on the backend server to make sure only approved clients can access the backend.
  • PUBLIC_API_URL - This is the url of the backend server.
  • PUBLIC_EVENT_NAME - This is the name of the event that will be displayed on the website.

The frontend is a svelte application, so you'll need to install the dependencies and then can either build the application or run it in development mode.

npm install
npm run dev

The website will be available at http://localhost:3000.

Backend

Like the website, you'll need to create backend/.env based on the backend/.env-template file. Here's a little more about each of the variables.

  • APP_PASSWORD - This is the password that is required to access the backend, needs to match the password specified in the website.
  • TWILIO_ACCOUNT_SID - This is the account sid for your twilio account (note: twilio not supported yet).
  • TWILIO_AUTH_TOKEN - This is the auth token for your twilio account (note: twilio not supported yet).
  • TWILIO_PHONE_NUMBER - This is the phone number for your twilio account (note: twilio not supported yet).
  • SMTP_USERNAME - This is the username for your smtp server you want to use to send emails.
  • SMTP_PASSWORD - This is the password for your smtp server you want to use to send emails.
  • SMTP_HOST - This is the host for your smtp server you want to use to send emails.
  • SMTP_STARTTLS_PORT - This is the port for your smtp server you want to use to send emails.
  • SMTP_SSL_PORT - This is the port for your smtp server you want to use to send emails.
  • SMTP_SOURCE_EMAIL - This is the email address you want to send emails from.
  • USE_SIMULATED_CAMERA - This is a boolean ("true", or default "false") that determines whether or not to use a simulated camera. This is useful for testing the application without a camera. The mp4 to use for the simulated camera needs to be specified in backend/simulated.mp4.

The backend is a python application that uses the gphoto2 bindings to control the camera. You'll need to install the dependencies and then can run the application.

You might need to install some dependencies for gphoto2 or the binary itself. I remember that I had to install some dependencies on my RaspberryPI to get it to work, although sorry I don't remember what they were.

pip install -r requirements.txt
python3 server.py

The backend will be available at http://localhost:8000.

Using SSL

If you want to use SSL, you'll need to generate a certificate and key and put them in backend/ssl/cert.pem and backend/ssl/key.pem respectively. You can use the following commands to generate a self signed certificate and key.

openssl req -x509 -newkey rsa:4096 -keyout backend/ssl/key.pem -out backend/ssl/cert.pem -days 365 -nodes

Note: If you're using a self signed certificate, you'll need to open your backend url in a browser and accept the certificate before you can use it. I personally do this by going through the network tab, opening the failed request in a new tab by double clicking then hitting accept. When you refresh the website it should work.
