Hi guys,
I bought myself a QI charging board for my Nexus 4 a few days ago, and decided to build a dock out of the Depron I normally use for RC planes. Now I want to share my build-process to you, as well as the blueprints I created and used.
If you want to build one, too, you need the following parts/tools:
After you printed the pages of attached PDF to an A4 paper, you can softly glue the first page onto the Depron sheet with some sort of spray glue, I used 3M SprayMount for it.
Wait with the second page, for now.
Then cut out the parts with the knife, be careful not to hurt yourself! The knife should be very sharp that the Depron gets cut cleanly, and doesn't rip.
Don't cut out the parts marked red in the blueprint, they should only be slit slightly. After you finished one part, you can safely remove the paper from it, use the knife to pull it away. Put away all parts except the ones with the red mark. Use the knife to remove a layer of about 1mm inside the red circles, look at the picture for a template.
You do the same at the position where we later store the cable, look again at the picture for a template.
Remove the coil from the board with a soldering iron, as the cable is too short currently. Solder the coil onto piece of cable then, don't connect the cable to the board by now!
Glueing time!
Begin with the parts which hold the QI coil: first put the coil into the backplate, then glue the front plate on it. My glue required me to put glue on both sides, wait 10 mins, and then stick them together.
While the backplate dries, glue the two triangles to the long rectangular, this will later keep the phone from sliding to the front/hold the phone at the charging plate.
After everything has dried, glue the front part to the backplate.
Glue the triangle to the backplate like this:
Now take one of the bottom plates, and cut a hole for the cable. I marked the position with a pencil, I suggest you doing the same. Glue the bottom plate to the other parts.
Now it's time for the second page of my PDF:
This page should either be glued to an 6mm Depron sheet, you then only need to cut out one of the parts, or you glue it to a sheet of 3mm Depron, and cut out both parts, which then will be glued together.
Glue the just created part on the remaining bottom plate from the first sheet, and lay the circuit board into it.
Cut the cable from the coil to a suitable length and solder it to the board. Be very careful while soldering, Depron melts easily, also make sure the cables don't get to hot! Then, you can glue the bottom case and the plate together, and you're basically finished!
In the end you can apply some finishing touches, like smoothening the borders/edges where you glued pieces together. You can of course also paint the dock in any color you like, I will maybe paint mine with a black acrylic dye later..
Result:
I hope you liked my little How-To, if you have any suggestions or ideas, feel free to comment.

If you want to build one, too, you need the following parts/tools:
- 1x A4 sheet of 3mm Depron
- 1x A4 sheet of 6mm Depron (or another 3mm if you don't get 6mm)
- a SHARP cutter knife
- UHU® Por Styropor-glue or similar glue
- my attached blueprint as PDF and dxf for LibreCAD
- and of course, a QI board, e.g. Amazon.de | Amazon.com
