Make:SF South: Kill Your Phone (or at least hide it) 9/23 - TechShop San Jose
Details
Did you know your phone can be accessed (and tracked) remotely or transmit its location, even if you're not using it (https://www.techdirt.com/articles/20130723/12395923907/even-powering-down-cell-phone-cant-keep-nsa-tracking-its-location.shtml)? You don't need to actually kill your phone to stay safe from the snoops, though.

It's possible to shield your phone or wallet by putting it in a Faraday cage, and in August we're going to learn how. Using fabric that's opaque to radio and wireless signals, and a tiny amount of sewing savvy, you'll make a pouch that fits your phone or wallet and prevents signals from getting through.
Come learn about conductive (and shielding fabrics) in this crafty Make:SF meetup.
This workshop is inspired by the Kill Your Phone project (http://killyourphone.com/).
How does it work?
A Faraday Cage (http://en.wikipedia.org/wiki/Faraday_cage) is a conductive container that blocks electromagnetic waves from passing through it. You might experience this when your phone loses signal when you're inside a metal elevator.
