This metal wafer can is what I keep my digital storage cards in. I started doing this a few years ago when there was talk of sunspots causing problems, long before this discussion.
what's affected by these EMPs? Just things with ciruit boards or is any electrically powered item at risk? (I'm thinking about my laptop and light fixtures...)
I used to keep the old important 5 1/4 inch floppy disks on one of my childhood bookcase with metal plates convered to prevent any magnetic stray coming in. I think I still have it contained for about 20 years and now these old 5 1/4 floppy disk/drive are obsolete
