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

Just for the look of it, I peeled off one of the stickers covering the charging coil. This lets itstick to the inside of the phone case, too!

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!

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!

Make sure the book can close fully, and plug in the USB cable to verify the phone will chargewhen placed on top.

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!
