picam

#how it works:

• function to take a photo using the raspicam
• function to upload photo to google drive
• call this function with a cron job

#inspiration

#requirements: gdata-python-client

https://developers.google.com/gdata/articles/python_client_lib?csw=1

google-api-python-client

• first install python-setuptools via apt-get
• then install pip http://www.pip-installer.org/en/latest/installing.html
• then pip install --upgrade google-api-python-client

Daylight

Simple function to return true if the current time is between sunrise and sunset.

Current intened use if to stop the raspberry pi cam taking photos when its dark.

Requirements

• python dateutils to parse date string to timedate sudo apt-get install python-dateutil

Plan

• Get sunrise/sunset times from openweathermap.org
• Parse xml to time or datetime
• compare time now with these times to return true/false

Further...

To avoid having to call the weather web service every time:

• function, called daily by cron to save the xml file locally
• adjust is_daylight to read local file instead of api call if its present, but fall back to the api call if file is missing.
