Shoot timelaps with the py Camera with raspberry Zero and move it to Google Cloud Storage

README.md

#Add two chronjobs for shooting images and uploadng to GCS

sudo crontab -e
#start camera script on startup
@reboot sudo -u pi /usr/bin/python /home/pi/timelaps/timelaps.py 2>&1 | /usr/bin/logger -t TL_CAM

#run movetogcs.sh file once per minute - ony one instance is allowed 
* * * * * /usr/bin/flock -n /tmp/movetogcs.lockfile sudo -u pi /home/pi/timelaps/movetogcs.sh 2>&1 | /usr/bin/logger -t TL_MOVETOGCS

##todo

• add ini file with configuration data
• add overlay to images before uploading to gcs
• create video from local files
• • create video from gcs files
• upload to youtube channel
