One of the things I thought I might do, is attach a webcam to a Pi, so I can see what's going on outside ... even when I'm not home. For that to work, I need to attach a USB webcam to one of the Pi's usb ports, and get some software that will take snapshots.
I already have a suitable cam, and in the past, I've used "motion" for this task. But that was on Fedora linux, on an Intel chip. Still, it's worth a try.
"apt-get install motion", and a quick edit of the paramters, and a quick adjustment of the webcam's focus, and voila - it worked! A couple of minutes after starting this project, I was seeing pictures of outside the house.
So far, I haven't thought of anything that I'm already doing on a Fedora Intel box, that I can't do on a Pi.
I've now set up a backup system, that will back up the Pi to my backup system, automatically, each day.
