So far, although wireless charging technology has begun to be familiar to everyone, most of the smartphones on the market itself do not support wireless charging function.

In fact, wireless charging is not what a very complex technology in the intelligent mobile phone, just add a pair of internal to transmit and receive electric coil consisting of a small magnetic field, therefore, as long as the understanding of the principle of it, can be very cheap means for the intelligent mobile phone manual own this. As a result, DIY's own wireless charging function can not only recharge our mobile phones at all times but also give ourselves a sense of achievement.

Whether you are Android, iOS, Windows Phone or BlackBerry, manual DIY wireless charging is not too hard, and it doesn't cost too much. Now there are already some third-party wireless charging modules on the market, with receiving coils and circuits in very thin plastic films.

Some of these modules are generic, and some are only used on special models. All the components work the same way, only the output voltage and the installation method are not the same. For example, some Galaxy Note 4 wireless charging modules do not need to connect to the MicroUSB interface, but are directly connected to the battery inside the mobile phone and the output current is 600mAh.

Therefore, if you use the intelligent mobile phone battery is not removable design, then it can only use the method of an external receiver module; and if it is to open the back cover to see the battery, then the built-in module is more suitable for you, this will not damage the integrity of the appearance of mobile phone.

How To Make A Wireless Charger for iPhone?
First, buy Qi charging module pcba on Amazon, (the left circuit board and coil on the left side) and Qi wireless charging receiver  (the right white chip).



The port of the Qi wireless charging is gilded and has a strong sense of texture and connects to the iPhone's butt. In actual use, you need to wear a softshell as a package.



Then buy the small boxes of plastic containers according to the size of Qi charging module pcba.



With a USB interface hole can be opened. The box looks very thin, but it is not easy to open the hole, and you must pay attention to the slippery hand. It is one thing to affect the beauty, and it is not worth it to hurt the small hand.



The black protruding position is the buzzer, just a plane. Confirm the position and drop the glue on it, and the air is solid for a few minutes.



Turn over and look at the coil, because the height of the box comes out more than 13-7 = 8mm, and the coil is active inside. Although it is tested, this distance can also be charged, but random sloshing must affect the stability of the charge. Try to reinforce it.



Find a piece of white pearl cotton, CF box size cut a rounded rectangle, and then cut out one slot, the two wires are used to pass through both ends of the coil.


Into the box, get off. The coil is pearl cotton top on the inner wall, and they will not run.


That's the way the circuit board is. By the way, the glue is used in the sun. The advantage of this glue is to be close to transparency after solidification, unlike the white one after 502 dry.


There's a great success here.

How To Make A Wireless Charger Receiver For Mobile Phone At Home?

The principle of wireless magnetic induction technology is very simple. You don't have to think how deep it is, because technology has already been realized in various components. What we need to do is understand the big principles and assemble them.

First of all, we have to prepare the following materials and tools:
Electric iron, solder wire, insulation tape, double-sided tape, copper foil stickers (used instead of other conductive sheet), slotted screwdriver, grinding plane, pencil, knife, copper contact, sandpaper (coarse and ultrafine each one),the stone set (including DIY wireless charging charger, data line, stone, charging circuit board)


DIY Steps:
The first step, preparation of materials, stone charging suit, a set of tools (including a screwdriver, sandpaper, modified pencil, knife, electric iron) as shown below.





The second step is to place the stone on the back of the back cover. The location of the four positioning iron plates is placed in the middle of the rear cover, and the coil of the charging circuit board is welded out. The coil is placed in the middle of the locating iron plate, and the mark is made with a pencil.
As shown in the picture.



The third step is to arrange the circuit board under the bottom part of the electronic component and the camera hood under the rear cover, and keep the distance between 0.5mm and the pencil.
As shown in the picture.



The fourth step, will make the mark part (the shaded part) surrounded by a knife to draw less than 0.5mm depth, and a screwdriver for the transformation of the smooth plane groove does not exceed 0.6mm.
As shown in the picture.



The fifth step is to put the coil and the circuit board into the groove, measure the distance between the coil and the solder joint, and use the enameled wire to weld (and connect the elastic metal contacts on the output contacts of the circuit board to the tail direction of the circuit board, and the length is about 3mm).
As shown in the picture.



The sixth step is to paste the electronic component part of the circuit board and the positioning iron sheet on the rear cover with double-sided adhesive.
As shown in the picture.



The seventh step, the metal shield attached to the coil, and the position of the position of the position of the positioning iron sheet, and then the tail of the circuit board attached to the top.
As shown in the picture.



The eighth step, open position corresponding to the thermal stickers on the motherboard metal shield, a shield, and at the end of the monitoring point with the motherboard metal shield insulation stickers affixed to the insulation monitoring points outside the third monitoring points will also paste insulation stickers, copper foil paste (available thin copper film (paper) according to the shape of cut paper), and welded to the third point detection.
As shown in the picture.

To complete these eight steps, the great success, the charging...
