Jim,
Just a quick note to those interested in obtaining a simple cost-effective Faraday Cage-like enclosures to protect small to mid-size electronic devices. As has been mentioned in SurvivalBlog before, the large steel cans of popcorn sold at the large box stores this time of year make great EMP-proof storage containers. After emptying the popcorn just place your electronics into the can and place the lid on top. No need to ground the container.
I place my Fluke multimeters, spare Solar charge controllers, spare handi-talkies and mobile radios in these tins. Thanks for all you do. – Larry D.
