I was going to build a Faraday Cage from copper rods and copper screen, soldered together. I also thought it would look cool, but also kinda pricey!
As I explained the concept of a Faraday Cage to a Liberal Geezer (thinks prepping is just crazy)...he suggested just using a Microwave! It keeps radiation in, it should keep EMP out! Totally logical and in addition, my new Microwave is metal and has a grounded plug! Uh huh.
I "Googled" this idea and sure enough other preppers though of the same thing. One problem...it doesn't work! I tested it this morning. My Microwave is a 1000W metal cabinet. I turned on my iTouch4 to do a Wi-Fi Speed Test and put it inside (No I didn't power-up the Microwave!). Unfortunately the Wi-Fi signal still got through....although, the signal was reduced by 50%. I'm sure the EMP signal would also get through and "goodbye" electronic gizmo's & their chargers!
Plan B...I am going to get an enclosed tin box....insulate the inside and try that in the Microwave. I'll put an addendum to this post on results!
