For fun, I’ve set up my laptop to take screenshots and pictures from the webcam every hour. These images are stitched together and dropped in a folder on my disk. I haven’t really found some great usage for this yet but it is quite fun to look back at every now and then.
The script produces images like the ones below.
I use a couple of programs to acheive this result. First, to setup the cron job I use this line
00 * * * * source /Users/jontelang/.bash_profile; snapimage;
snapimage is a method that I have made that is inside my bash profile. So I tell the cronjob to use this file, then I call the method.
The method itself looks like this:
The actual flow in the script is pretty straight forward so I won’t bother to explain. But the things used needed some scavanging for.
imagesnap is a downloaded program that takes images from the webcam.
convert is a progam in the ImageMagick suite.
screencapture was bundled with OSX as far as I know.
Sometimes it is fun to see what happened while you were gone.
