A simple script that takes a picture every day at solar noon.
- It uses
raspistill
to actually take the picture but any command can be used. - It outputs files named using an ISO-8601 date:
YYYY-MM-DD.jpg
(use--nameFormat
to customise this).
./timelapse.sh --lat 19.717586 --lon -155.547864
-d --directory
Directory to store images in (default: '.')
--lat
Latitude of current position. If omitted geolocation will be attempted
-r --retries
Maximum number of times to retry fetching solar noon date (default: '6')
--lon
Longitude of current position. If omitted geolocation will be attempted
-h --help
Show this help message
-f --nameFormat
Format of image file names. Uses standard date formatting (default: '%Y-%m-%d.jpg')
10 Image storage directory is not a directory
11 Image storage directory is not writable
20 Unable to do geolocation
30 Solar noon fetch retry count exceeded
It's a good idea to run this as a service so if the script is killed for any reason it is restarted and can be set to start on boot.
To do both these things simply copy the included solarTimelapse.service
file to /etc/systemd/system/solarTimelapse.service
and run:
systemctl start solarTimelapse
systemctl enable solartTimelapse
Note this service is assuming you have cloned the code to /home/pi/solar-scynchronised-timelapse
- Uses sunrise-sunset.org to fetch the solar noon time
- Uses ip-api.com to do IP based geolocation. This will be skipped if
--lat
and--lon
are passed
