Python process that publishes photos taken by a Raspberry Pi camera to a Pusher channel

picamera-pusher

Python script that takes pictures at a certain interval with the Raspberry Pi camera, then save them to a web server and publish the URL to a Pusher channel so an iOS app can show them in a realtime photo feed.

You can follow the tutorial to build this application or jump straight to the code.

Getting Started

1. Make sure you have all the development dependencies installed in your Raspberry Pi by executing sudo apt-get install build-essential libssl-dev python-dev libffi-dev.
2. Install a web server.
3. Create the directory photos under /var/www/html/ and give it permissions (by changing the owner):
   • sudo mkdir /var/www/html/photos
   • sudo chown -R pi:pi /var/www/html/photos
4. Clone this repository and cd into it.
5. If you didn't have virtualenv, install it with sudo pip install virtualenv.
6. Create virtual environment for the project with Python 3 virtualenv -p python3 env.
7. Activate virtualenv with source env/bin/activate.
8. Install requirements with pip install -r requirements.txt.
9. In another terminal, execute ngrok with ngrok http 80 and copy the URL with HTTPS.
10. Modify the file camera.py to enter your Pusher credentials and ngrok URL. You can also change the time to take photos.
11. Execute python camera.py.
12. When your done, stop the program with Ctrl-C and deactivate your virutal environment with deactivate.
