100 ways to play mobile phones, how do you "treat" your mobile phone as a programmer?

Abstract: In life, in addition to the existing applications in mobile phones, we can also use mobile phones to do many things. For example, write an APP yourself, bring your own encryption algorithm, and use it to sense the automatic door opening. No one knows your algorithm, so compared to the ones on the market, the security is very high. You don't need to take your keys when you go out. Another example is if you are too lazy to get up and turn off the lights in winter. You can directly turn off the lights, turn off the TV, turn off the air conditioner, close the door, and turn off the lights in the bed.

Programmers engage in basics, oh no, I mean that they should be very professional. Just a line of code to an infinite loop, let the machine die in minutes. emmmmm... This skill seems useless, here is a useful one, such as the picture below, for Cheng Yuan, it is both practical and distinctive.

Also expand the screen of the mobile phone to 100 inches to watch movies and play games:

Of course, these are relatively low-end solutions, after all, they are all implemented through peripherals. The mobile phone's own projection is the real technology. So is there a way to achieve this? Texas Instruments' latest HD DLP Pico chip (with "Tilt and Roll" technology) has successfully reduced the size to 0.3 inches. As the owner of DLP technology, Texas Instruments has launched DMD chips and corresponding video processing chips for the projection market, which are called DLP Pico display technology and a series of DLP product solutions. The DLP Pico chipset provided by Texas Instruments mainly includes two devices: a digital micromirror device (DMD) and a display controller. Some chipsets also include PMIC/LED drivers. In the DMD chip, the micro-mirror is the smallest unit of work and the key to its performance. Micromirrors are very small, but still have a complex mechanical structure different from liquid crystals - each micromirror has an independent support frame and is deflected by +/-12° around the hinged oblique axis. For micro-machines such as micro-mirrors, traditional mechanical or hydraulic control can no longer be used (even if they can be used, they will be quickly damaged due to mechanical wear), so two electrodes are arranged at the two corners of the micro-mirror, through the voltage Controlling the deflection, high-precision control capability and infinite polarization lifetime are obtained.

When DMD works, each micro-mirror is deflected by +/-12°

The current mobile phone battery is old and insufficient, and it has to be plugged in...pulled out...in... If the plug is broken, it only costs 10 yuan to repair it by yourself, but it is too difficult. Send it to the store for repair, and it is 2,300 maintenance fees at every turn. But if you use wireless charging, it's a lot easier all of a sudden. Just put it on the top:

There are five mainstream wireless charging standards: Qi standard, Power Matters Alliance (PMA) standard, Alliance for Wireless Power (A4WP) standard, iNPOFi technology, Wi-Po technology.
Qi is the "wireless charging" standard launched by the Wireless Power Consortium (WPC), the world's first standardization organization to promote wireless charging technology. It has two characteristics of convenience and versatility. First of all, products of different brands can be charged with Qi wireless chargers as long as they have a Qi logo. Secondly, it overcomes the technical bottleneck of "universality" of wireless charging. In the near future, mobile phones, cameras, computers and other products can be charged with Qi wireless chargers, providing the possibility for large-scale applications of wireless charging.
The mainstream wireless charging technology in the market mainly uses three methods, namely electromagnetic induction, radio waves, and resonance, and Qi adopts the most mainstream electromagnetic induction technology. In terms of technology applications, Chinese companies have been at the forefront of the wireless charging industry. It is reported that Qi's application products in China are mainly mobile phones. This is the first stage, and it will be developed and applied to digital products of different categories or higher power in the future.

Think about life, in addition to the existing applications in the mobile phone, we can also use the mobile phone to do many things. For example, write an APP yourself, bring your own encryption algorithm, and use it to sense the automatic door opening. No one knows your algorithm, so compared to the ones on the market, the security is very high. You don't need to take your keys when you go out. Another example is when you are too lazy to get up and turn off the lights in winter, and use your mobile phone to turn off the lights, turn off the TV, turn off the air conditioner, close the door, and turn off the lights in the bed.
Of course, all of this requires money to buy a bunch of smart devices first. But don't they all say that programmers have more money and less talk? So it's okay, it's not a problem.

emmmmm.... I seem to be talking about a problem with the mobile phone, do the programmers do it by themselves...
