Last Sign of Winter?

I noticed this little bit of remaining ice in the front of my house, where the snow had been piled from shoveling and it doesn’t get any sun. Hopefully this is the last sign of winter. I’m ready for some golf.


My front porch didn’t get hit bad, but the walkway and driveway are all ice. Over the last 10 days we’ve had a winter storm, record wind chills, a heat wave up to 50° that melted all of the snow, and now this freezing rain. Crazy weather changes!

April 14, 2018 Storm in Saginaw, Michigan

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.


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/

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 pi@pi.local:/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.

Be Careful with Ice

I took this picture about 24 hours after icing. This is what happens when you apply ice directly to your skin. Don’t do this.

BTW, taking a picture of your own back is no easy task.

Evaporating Ice Cubes

I filled up 2 ice cube trays a month ago when I got here and tonight is the first time I went to use the ice. I was surprised to only find half as much ice as I expected. I have never seen anything like this. The ice appears to have evaporated leaving only 2 points of contact per ice cube. Something to do with the air in Arizona? Or maybe the water?
