Qi Phone Case

Plug in the charging module to your phone's charging port, and tuck it against the back of thephone.

If your phone already has Qi charging support, you do not have to do this step! This isjust to demonstrate how to do add Qi charging capability to non-Qi phones

Qi Transmitter Book

You can put the Qi transmitter in lots of things! Make an acrylic charging stand, put it in a corktrivet, or, like we're going to do, stash it in a hardcover book.

Make sure it's a book you don't want to read, as you'll be cutting it up!

Use your favorite metal ruler and a utility orcraft knife to cut through many layers of bookpages along the outline. Watch your fingers!

The coil should be as close to the cover aspossible, but you might want to make the spotfor the circuit a bit deeper so the USBconnector is completely submerged in pages.

Don't forget to cut a channel for the USB cable!

Next place the phone on the book while its closed, lining up the coils so it's charging. Thentrace around the phone with a pen or pencil so you'll know where to put it when you want itto charge!
