Not long after the video was released on YouTube, it became the headline of major foreign technology websites such as The Verge, Gizmodo, and TechCrunch.
In fact, it’s 2021. The MacBook has a C port and the iPad Pro has a C port. This year, even the iPad mini has been replaced with a C port.
How to say, is my iPhone not worthy?
Now almost all portable electronic devices are Type-C, and cameras, Switches, and power banks are almost all C ports.
The application is already very wide.
And the Type-C interface is obviously better than Lightning in all aspects.
This Lightning, developed based on the USB2.0 standard, has a theoretical Type-C transmission speed that is more than 10 times faster.
And Type-C is compatible with multiple fast charging schemes such as PD and QC. In addition to its own 5V2.4A fast charging protocol, Apple only has the PD protocol, and the maximum withstand current is only 3A.
The most important thing is that Lightning does not yet support the transmission of analog signals, which means that if you want to transmit data or audio output, you need the entire Lightning adapter.
It’s 2021.
With more than 1 billion iPhone users in the world, everyone still has to bring a Lightning interface cable with them.
Everyone expects Apple to abandon this unsupported Lightning charging port all the time.
But he doesn’t…
Forget it, I couldn’t hold back when I complained about it, let alone Apple.
Let’s look back and see how a college student can replace the iPhone with a C-mount, and there is even no trace of modification.
By the way, he also received support from the mysterious power of China during this period. Let’s talk about it later.
In order to make it easier for everyone to understand:
Here we put Lightning charging plug calledMale L , Call the Lightning charging portFemale L 。
Same for Type-C,Call the C port charging plugMale C , Call the C port charging interfaceMother C 。
Then the magical place came.
Looking at the picture below, we made the pile of things on the back of the phone smaller and put it into the iPhone, so that the female C could replace the female L on the original iPhone, and the C-mount iPhone was born.
After reading it, does it feel like a sudden realization, “So it doesn’t seem to be difficult.”
Although this idea is unpretentious and understandable at a glance, it is quite difficult to have a few detailed points.
First of all, if you want to put things in, you have to make the next thing as small as possible.
For example, for this C to Lightning cable, you can’t just plug such a cable directly into the iPhone as shown in the picture.
Therefore, it is necessary to clarify the connection relationship between female L to male L to male C and then to female C, and then use a soft cable to establish the relationship between female L and female C directly.
How to figure out the relationship between these lines?
Try one by one!
Take out the electrical tester, try out the connection relationship between these wires one by one, and then use the flat wire to reproduce the connection relationship.
In addition to trying out the connection relationship between the interfaces.
We have to dissect the female L connector at the end of the phone.
The interface part of the female terminal L of the mobile phone is probably as long as the bottom. After anatomy, the Lightning part is broken to the outside.
Then add a cutter head to the welding torch, and separate the female L interface body from the black flat cable below.
After decomposing the female L, let’s disassemble the male L docked with it.
The meaning of disassembly is to throw away those unnecessary packaging parts, and make it smaller after docking with the mother L, so that it can be stuffed into the phone.
But ……
There is a problem here. The quality of the original male L plug from Apple is really good.
The blogger used electric knife sharpeners, electric saws, electric drills, etc., but still didn’t rub them apart. He had no choice but to buy a bunch of third-party plugs before disassembling the Lightning plugs.
After disassembling, the key figure inside is the C94 kit chip, which can be charged and relied on.
So we have to dissect it before proceeding to the next step.
However, this original C94 is rhodium-plated, which is very hard.
And it also uses the SHA256 encryption algorithm that cannot be cracked like Bitcoin, so it can’t be cracked.
This C94 kit is not easy to remove from the line, if it is not done well, the cost will be high.
At this time, he set his sights on Taobao (Taobao), which is far away across the ocean.
There are C94 kits sold directly above, you don’t even need to disassemble them, the key price is still cheap.
With the support of this mysterious Eastern force, there is no need to crack any C94 encryption algorithm, and by the way, it also avoided Apple’s lawyer letter for the blogger.
After shipping it back, figure out the logical relationship of this FakeC94, and then you can turn the next thing into a small PCB board and cable.
Let’s take a look at the physical map display of the engineering version.
But this is not enough. We have to put the pile of things exposed outside into the phone, which is still a bit big now.
So the blogger redesigned and printed the interface with a 3D printing tool, and redesigned the circuit with Allegro (a PCB board design software).
The ultimate thing is the following.
The complicated line relationship has been clarified, but there is still an immediate problem.
The current Lightning interface is too narrow to replace the C port directly, so I have to find some tools to make the opening bigger.
but……
If you are hard, you may crack the screen or even the glass back plate when you drill the interface, so the blogger found a very fine tool and slowly grind it from the inside out.
Finally, close the screen cover crisply, and the whole transformation process is over.
At present, the blogger has auctioned off this prototype on eBay, and the price was 3,400 US dollars when it went on sale on November 2nd.
Now it has soared to 100,000 US dollars.
Of course, this phone cannot update the system, let alone water, and you can’t even use it as a normal phone.
However, the blogger has also open sourced the entire project process (except for the PCB design schematic), and will develop other models of iPhone besides iPhone X in the future, and will also add fast charging and waterproofing.
Below the video, there are already many netizens urging to change the C port for Airpods & Airpods Pro.
And back to Apple, in a phrase that hates iron but does not make steel:
“Hurry up and send the world‘s first hand-built C-mount charging iPhone to Apple Park, let Guo Guo open his eyes and guide them on the key development direction of iPhone in the next few years.”
“Put the C port back, get the charging head back, and throw away the Lightning charging cable.” There is also environmental protection, and the charging head is back. Isn’t everyone happy?
Why is Apple not willing to abandon Lightning?
The reason for the most speculation in the industry is that Apple is reluctant to receive MFi certification.
What is MFi? Made For iPad&iPhone&iPod
It is a kind of logo license of Apple’s authorized accessory manufacturer’s external accessories.
To put it bluntly, it has MFi certification. This line is produced under the strict supervision of Apple. It has a set of official standards for voltage, current transmission, and charging rate.
Without MFi, your charging cable may not be available.
Of course, the MFi audit is also quite strict.
Including MFi member application review, product review, product testing review, self-built factory review, review of an area not less than 2000 square meters, review of no less than 50 employees, and so on. .
It is said that the pass rate is only 2%.
After passing this certification, every Lightning charging cable produced in your factory must have a built-in MFi chip that can only be purchased from Apple, and each chip is $2.
One can imagine how much money Ago will make from this every year…
But having said that, it’s the same thing to have multiple wires and fewer wires, mainly because it’s not Apple if you don’t abandon Lightning after so many years.
You dared to cut off the Mac optical drive, HDMI, and memory card interface drastically, and replaced the Mac radically with a full Type-C port.
Now, why can’t a small Lightning interface be cut off? Our 1 billion iPhone users are really not as good as the money you earn from MFi certification?
So, Ago, it’s time to take off your AirPods Max, listen to the user’s voice, and have a break with Lightning.
