DIY Book Qi Wireless Charger

So now that wireless charging is going to be all the rage, with iPhone 8 and X being Qi compatible, I wanted to make one after finding out how expensive they could be. Qi charging boards are easily found online, and I got one off ebay for USD2 (includes free shipping). An example is http://www.ebay.com/itm/192058072543 (note that there are many others, this is just what I got). You will need a cutting mat, glue gun, ruler, marker, and of course a book. I decided to use my son's old Slinky Malinki as he is all grown up now, and cardboard was a _little_ more heat resistant than paper (in future, I will be adding some kapton tape just to be sure).

Phone 8 and iPhone X's induction coil is located dead centre of the devices, and I decided to put the charger induction coil the same, and the board near the edge were the micro-USB connector would be.

For this book, I found that I needed to cut 3 layers for the circuit board, and 2 for the induction coil. This excludes 2 layers (including the cover) which is well within the 4mm range tested for iPhone 8 with the case.

I decided to use hot glue because it was faster, but you can use any wood/paper glue. When you clamp it together, glue will likely leak out. Just trim them off once they are hardened.

The rest should be relatively straightforward. Mount the coil and board using more hot glue, test and you have a bedside Qi charger.
