On Thursday it was 64° when I ran outside. Then we had a winter storm come through the weekend.
Since it’s rare to get a storm this late in the year, I thought it would be neat to document it.
My makeshift ruler and stand was a complete failure; it blew over, spun around, and wasn’t readable. I’m happy with the rest of the project though. I really like the worms crawling around, seeing the water freeze, and how the lines of the bricks come through.
I used a Raspberry Pi Zero W and the camera module.
In order to get images for the time-lapse I added cron job that ran a bash script every minute, which in turn called raspistill to capture a photo. It was very easy to set up. Here is the bash script.
#!/bin/bash DATE=$(date +"%Y-%m-%d-%H-%M-%S") raspistill -vf -hf -o /home/pi/time-lapse/images/$DATE.jpg
This is the line I added to my crontab.
* * * * * /home/pi/time-lapse/capture.sh
Before transferring all of the images to my Mac, I compressed the images folder.
tar -czvf images.tar.gz images
Then, from my Mac I could grab them by doing a secure copy.
scp email@example.com:/home/pi/time-lapse/images.tar.gz images.tar.gz
In order to stitch everything together, I imported the images into iMovie, changed the crop style to fill, and set a 0.01 second duration.
