Hello!
Since the very first appearance of phones equipped with wireless charging, this feature has become one of those that I prefer to see on my phone's spec sheet. It is actually convenient and practical.
In this case, a wireless charger is most often a kind of module of various shapes, which is equipped with an induction coil.
In the latest generation of its devices, even the company Apple, which until recently denied the need for wireless charging, went along with the market and equipped iPhone the 8/8 Plus / X with a wireless charging module.
Let everyone decide for themselves the need for such a function in a smartphone, today we are not talking about that. Today I decided to try to implement my old idea – equip a desktop with wireless charging, making the process of charging a smartphone even easier.
But before sawing my main table, I decided to test the very possibility of such a solution, and as a test subject I chose something that I don't mind spoiling – an old coffee table from Ikea.
For a long time using wireless charging modules at home, a lot of these same modules have accumulated. The donor of the induction coil will be a wireless charger from LG, which was once bought at Svyaznoy for a promotion for some very ridiculous money.
Let's get started.
First, let's disassemble the table so that it is easier to cut it.
Then we mark the area where we plan to place the coil.
We disassemble the module to estimate the size of the coil without the case.
The dimensions are very modest. We see a massive metal plate on the module – we don’t remove it, it’s a radiator – cooling the coil, which heats up noticeably during operation.
I was confused by a rather flimsy cable running from the microUSB connector to the main charger board.
Subsequently, we will replace it with good old wires. This will not only add reliability to the design, but also make it possible to bring the connector to the end of the table, which will significantly increase mobility and reliability. But that's all later. Now our task is just to check the viability of such a solution, so we leave the loop like this.
Well, then we cut out the marked area.
We see cardboard stiffeners inside (sounds funny) – remove them.
Trying on the module – it fits!
The only thing left is to fix the module and cable, and you can use it.
Given the very modest thickness of the tabletop, we use glue for fasteners.
In order not to damage the cable, we attach the wire to the bottom surface.
We turn the resulting structure over and connect it to the power supply.
Hurrah! The theory turned out to be correct, the thickness of the tabletop is not enough to extinguish the signal from the coil, and our phone is charged just lying on the table. Convenient and unusual. I definitely like the new furniture option.
By the way, in the frame there is an old, broken Nexus 5, which fell under the arm, since it was not possible to take pictures with your phone and charge it on the table. ?
Conclusion
Well, the goal has been achieved. Now I'm going to think about electrifying my main desktop. Unlike the Ikea 'cardboard' coffee table, the top of the main table is made of a solid piece of wood, which means you have to work hard to drill a hole in it without cutting through the table. This will require a lot more tools and a little more skill. But where did not ours disappear! I was a soldering master, now I have to become a carpenter as well. Now I have plans to equip all tables in the house with wireless charging modules.
Dare and try – it's interesting to craft. Holiday greetings!
