One Thing To Do Today: Time for some tinfoil

0

In action movies the experienced guide grabs the befuddled hero’s mobile phone and rips out the battery.   Fiddling with location settings helps, but that can’t prevent everything as this documentary about a guy tracking his cell phone thief shows. Even having the phone off, and the main battery out may not be enough.

Since my phone requires special tools to open, I’m sure my world-weary sensei would shake her head and simply chuck it out the window.  But I like my phone, and apparently other people like theirs enough as well to have spawned for a signal dead-zones industry.  Commercial Products abound, although my favorite have gone out of business.  It’s also fairly easy to hand make  ones own “faraday cage” bags. I’m hoping that member Barb Noren, of Barb Makes Things fame, will give me a sewing machine lesson sometime soon.  I purchased two kinds of fabric on Amazon, but LessEMF.com provides even more options.

Make sure to test your bag or case before relying on it. At Purdue a student did a master’s thesis on just that. Some bag making and usage advice… NO GAPS, make sure to close that flap.

Can’t wait for shipping? Stuff a phone into a fridge or microwave, but those aren’t particularly portable. A cocktail shaker should work as well. For super old school, but still effective, go tinfoil. No calls will get through with it all wrapped up like a burrito, but that’s the point after all.
