For so many years, there is a problem that has become more and more prominent.
It's what to do with those old phones.
Sometimes when I hear the shouting of "recycling old mobile phones and old computers", I want to sell it directly in a sack.
Or hang on to idle fish and sell them one by one for a good price.
However, that is the youth of the machine brother, ah, it is really a bit reluctant.
Of course, there are also some ways to use old mobile phones.
For example, add a base to transform into a desktop clock.
If it is an OLED screen, the display effect is really good.
The machine brother is not unconsidered, but this thing is too chicken.
It also does not meet the identity of the first machine master of Line 6.
So the machine brother I seriously looked for, to see if there is a more hardcore old mobile phone transformation.
I didn't expect to be eye-opening, but fortunately I didn't hang up my old mobile phone on idle fish and sell it.
Otherwise, the machine brother will really regret dying.
The old phone was replaced by a USB stick
Do you have some old mobile phones that have been damaged in battle?
It is the kind of "scrapped mobile phone" that explodes the screen, burns the motherboard, and the battery drum pack, and repairs the "scrapped mobile phone" that no one uses.
In fact, even if it is such a mobile phone, it still has use value.
Of course, it is not to refine gold.
Instead, the flash memory chip on the motherboard of the mobile phone is removed and transformed into a USB stick.
The transformation method is well, and the machine brother looks at it and thinks it is not difficult.
Take apart the old phone, find the location of the flash chip on the motherboard, melt the solder joint with a hot air gun, and you can remove it.
Also prepare a main control board of A USB stick, which is also easy to buy.
What is the master?
Everyone understands the flash memory chip as a pool of water, and the main controller is the pump responsible for releasing and pumping water.
It probably looks like this.

The next step is to clean the pads, plant tin for the chips, and finally use the hot air gun to solder the flash memory.
This part of the operation machine brother will not unfold, after all, everything that is understood is understood, and those who do not understand will not try.
Finally, it is to connect the computer, use the software to brush the data into the main controller of the USB flash, and let the computer recognize it as a storage device.
At this point, the core part is complete.
Some friends may ask, so troublesome to make a U disk, in addition to waste utilization, is there any sense?
Needless to say, the U disk made by this magic change is really something.
Now the common flash memory chips in mobile phones use at least eMMC 5.1 this level, and the performance and mainstream U disk are similar.
If it is UFS 2.1 or even higher specifications, the read and write speed is seconds to most U disks.
However, there is also a price to pay, that is, the fever is a little high.
Therefore, DIY big guys generally choose metal shells to help dissipate heat.
The old phone was replaced with night vision goggles
At first, the brother did not believe it, what is the relationship between the mobile phone and the night vision goggles.
In the impression, in addition to the use of those night vision goggles by the army, only some military fans with banknote ability are playing.
However, after seeing the demonstration of the results of the modification, I took it.

Where you can't see your five fingers, you can really take a picture.
It's just that people's genuine night vision goggles are green, and the version of this mobile phone magic change is a miserable red.
The key is infrared.
In fact, the sensor of the mobile phone camera can capture infrared rays.
However, in order to make the imaging effect closer to the senses of the human eye, infrared rays are generally filtered out and only visible light is retained.
Therefore, as long as the infrared filter in the mobile phone lens is removed, it can restore its "strength".
Of course, it is extremely difficult to remove the mobile phone lens, and it will be scrapped if you are not careful.
However, even if you have the ability to shoot infrared rays, it is still not enough.
It also needs to be filled with light, which is the same as the usual video shooting, but the infrared is not visible to the naked eye.
So the last thing to appear is the infrared lamp bead, which is in your remote control.
When everything is ready, they can be assembled with a shell.
Brother Ji to be honest, this old brother made this shell, it is really a bit sloppy.
Don't worry, you can use it.
As soon as the infrared fill light is turned on, how dark the place can be seen, in fact, it is very similar to the surveillance camera with night vision function.
Have such a night vision goggle that you can take out.
Then the machine brother can go deep into the dark woods...
Go and take a picture of the stray little wildcat.
Linear motor to resonant sound
The next one, it's a little magical.
It's not unusual to take out the parts of an old phone and change it to a small stereo.
But if the vibration motor is changed to a speaker, many people may not believe it.
Of course, this is not the "buzzing" ordinary rotor motor used here.
Instead, use a linear motor, preferably the Taptic Engine on the iPhone.
Eh? How can a linear motor be a sound?
The machine brother came to give everyone popular science popularization.
The essence of sound is vibration, and the performance of the linear motor is good, and the vibration frequency and amplitude can be precisely controlled.
Many mobile phones provide vibration modes, and some can feel the rhythm.
Then it is necessary to find a sound emitter, attach the linear motor to it, and the vibration can be transmitted to make a sound.
This is like a mobile phone on the desktop, the vibration will be very loud.

In short, it is such a principle, and as for the transformation, it is also very simple and rude.
Just buy a Bluetooth audio driver board, fly two wires connected to the linear motor on the line.
As for whether to shell or not, it depends on personal preference.
Bluetooth is connected, the motor is on, and you can hear a different sound if you casually shake it on a larger thing.
For example, get on a chip wafer and feel the most cyberpunk electronic sound.
Or stick to your helmet and enjoy true 360° suffocating surround audio.
Tell the truth, just rush this, the machine brother is moved.
4K phone to projector
This one is really beyond most people's understanding.
The modification program came from a foreign big man who gave an extremely detailed tutorial.
The content involves: metalworking manufacturing, high-power LED cooling system construction, focal length measurement of Fresnel lenses, circuit testing and adjustment, belt synchronous wheel screw installation...
All in all very complicated.
But who is the machine brother, is this something still unclear?
Speaking of people, this old brother used a mobile phone screen to create a projector with a fairly good effect.

The various tedious steps mentioned in it are all for the core projection function.
This mobile phone screen is the 4K LCD screen on the Sony Xperia Z5P.
The liquid crystal layer of the LCD screen is actually translucent, and the image can only be displayed normally after backlighting.
As long as you take the phone apart, remove the backlight layer, and give a light source, you can project the image.
The difficulty is actually mainly the design of the optical path.
As for the operating system, it is directly used back to the mobile phone, and the external key and mouse of the OTG function are used to get it.
The final imaging effect, the machine brother was shocked.
The picture is gorgeous, the details are rich, the corners are sharp, in short, it is a sentence, transparent!
Compared with the finished 4K projector of 10,000 yuan, the picture quality can even be beaten.
In the few minutes of watching the big guy's tutorial, the machine brother has shouted "Wonderful" 18 times.
The brother looked at the mobile phone full of drawers, and the disgust in his eyes had disappeared.
I suddenly felt that they still had unlimited potential.
How to deal with the old mobile phones in everyone's hands, don't you come to the comment area to show your riot operation?
