Have an Android phone with NFC capabilities? Make a multi-functional carrying case that automatically puts your ringer on silent, turns it up loud, or creates a Wi-Fi hotspot!
Watch IMG_0433.MOV below for an overview of what it'll look like and what it does.
If you don't have an Android (boo-urns!) then you can still use part of this guide (what you're looking at now) to make a case for ANY phone -- sans NFC tags.
Step 1: Gather Your Materials.
To make the paper sizing template:
* Blank sheet of paper
* Scotch tape or glue
To make the outer part of the case:
* Felt (or some other fabric for the outer part of the case)
* Thread to match felt
* Sewing pins
* Sewing machine (recommend but not required)
To make the inner part of the case:
* Foam sheet
To do the NFC stuff:
* 4 NFC stickers (the anti-metal kind): http://www.tagstand.com/collections/anti-metal-nfc-stickers/products/mifare-ultralight-white-metal-proof-nfc-sticker-circle-30mm-diameter
* Radio frequency blocking fabric: https://www.inventables.com/technologies/metalized-fabric
* Hand sewing needle
And, of course, you'll need a phone. (An Android device with NFC support is required to complete the entire project.)
