How to Make Waste Mobile Phones Exert Waste Heat

Tencent Digital News (Wen Xin) According to CNET website, smart phone technology is developing so fast that I believe many people have several old mobile phones that are eating ash at home. What do you usually do when your old mobile phone is replaced with a new one?

After buying a new mobile phone, many people have another choice besides leaving the old one in the corner to eat ashes, that is, selling the old one. But there is a problem with this method, unless it is a relatively new Android phone or iPhone, the old phone really can't sell for a few dollars.

Then the question comes: what should I do with the old mobile phone? Of course, there are many ways, but one thing is certain: don't throw it away. According to the report entitled "Garbage Crime" by the United Nations Environment Programme, it is estimated that in 20 17 years, human beings will produce up to 50 million tons of electronic waste-mainly computers and smart phones. Smartphones use a lot of metals, minerals and chemicals, which will become toxic when they are treated or burned in landfills.

This paper will explain several methods of "waste heat utilization" of old mobile phones:

A camera/video camera

I don't know about you, but CNET reporter Marguerite Reardon will take a lot of photos and videos with her mobile phone anyway. She has set her sights on Java digital SLR cameras. Rearden has children, so the smart phone is very convenient to carry, and you can take it out to take photos and videos at any time. However, she went to a place to play, but didn't want to bring her smartphone: yes, it was the beach. Intriguingly, she also likes to take pictures of children "eating sand"-oh, Rearden means building castles with sand and playing in the waves.

At this time, the old mobile phone eaten in the drawer at home can come in handy. Although Rearden's old Samsung Galaxy S3 may not be waterproof or dustproof, compared with the new mobile phone, she would rather let the old mobile phone risk getting wet by water, getting stuck in sand or being stolen. Because it supports WiFi connection, when hotspots are available, just like photos and videos taken by her current smartphone, photos and videos taken by her old phone will be automatically synchronized to Google Photos.

Bedside equipment/alarm clock/photo album/white noise machine

Mobile phone is an excellent bedside electronic product. Just prepare a charger base for it. First of all, it can be used as an interesting alarm clock, with unlimited customization ability. It can set multiple alarm clock times and even play the role of a calendar to remind users to attend scheduled meetings.

Secondly, the old mobile phone can perfectly display digital photos. There are a lot of applications in Apple App Store and Google Play App Store, which can turn mobile phones into digital photo frames.

On the bedside table, another excellent use of the mobile phone is the white noise machine. Similarly, there are many such applications. There are several free apps in the App Store and Google Play, so that users who have difficulty falling asleep can sleep peacefully in waves, rotating fans or rain.

Electronic reader

CNET said that whether you already have an e-reader, uninstall other applications on your old mobile phone, delete other stored files, download e-books and audio books, you can put your old mobile phone on the bedside table or next to your favorite comfortable chair. Applications such as Amazon Kindle can synchronize users' reading progress on multiple devices. Users can also use applications such as Pocket or Instapaper to slowly read good articles found on computers or smartphones at night or in their leisure time.

Television remote controller

If the phone is equipped with an infrared transmitter, please download TV remote control software, such as AnyMote SmartRemote or Sure Universal TV Remote. These applications and integrated infrared transmitters can turn old mobile phones into universal remote controls. It can also control other devices through infrared signals, such as DVD and Blu-ray players, cable TV set-top boxes, stereos and even air conditioners.

Even if the old mobile phone unfortunately has no infrared transmitter, you can control Roku, Apple TV, Amazon Fire TV and other set-top boxes or smart TVs through WiFi.

Vehicle navigation equipment

Two years ago, after living in New York for 17 years, Rearden moved to the suburb of Philadelphia. At first, she would get lost outside the community, not to mention finding the best route to the grocery store. As a result, mobile phones and Google Maps became the saviors of Rearden. Although she can go to shops and children's schools without GPS navigation now, she still needs the help of a mobile phone if she wants to go to a new place.

Although Rearden seldom doesn't carry the mobile phone she is using, she installed an old Moto X mobile phone in the car as a GPS navigation device. To use a mobile phone as a navigation device, you only need to download a part of the location map (downloaded from Google Maps) on the mobile phone. In this way, Rearden's mobile phone has completed the transformation from mobile phone to GPS navigator. It doesn't need to use mobile phone traffic, because all maps and navigation information have been downloaded to the mobile phone. The only drawback is that she can't get updated traffic information, or get timely notice and detour when there is a traffic accident ahead.

There are many good cycling routes near Rearden's home, so in their spare time, she and her husband will use their "Google Maps" mobile phones for fun. During riding, Google Maps phones can also record their riding speed. If you like, Rearden can also connect the "Google Maps" mobile phone with the fitness tracker through Bluetooth technology to monitor the heart rate in real time.

Music player

Turn mobile phones into jukeboxes and entertainment centers. If you have a Sonos sound system or other wireless sound system, you can use an outdated smartphone as a dedicated controller. Uninstall the applications on the mobile phone, delete all data, download favorite songs or streaming music applications, such as Spotify, iTunes and Google Play Music, and create a music hub to transfer music to Bluetooth or WiFi stereo. Of course, users can also add several internet radio stations, audio books or podcast applications to their mobile phones and listen to their exciting voices on the home audio system. The advantage of this system is that users don't need to set up Bluetooth technology on any other devices at home.

Virtual reality head display

We all know that virtual reality is the next important computing platform. There are several options for users to choose virtual reality headphones for smart phones. For users who don't want to spend hundreds of dollars to buy a high-priced virtual reality headset, it only takes 20 dollars (about RMB 133 yuan) to turn most old mobile phones into a low-end virtual reality headset.

babymonitor

You can achieve the same goal with an old smartphone that eats ash in a drawer. Why spend $65,438+000 or more on a video baby monitor? With the application of Dormi and baby monitor, users can transform their old mobile phones into baby monitors, and transmit the shot and recorded audio and video to the currently used mobile phones.

toy for children

If you don't want the babbling child to drool over the newly bought iPhone, you can fool him or her with the old mobile phone. Install parental control applications and applications and games suitable for children on your mobile phone. You can even download videos from your mobile phone and watch them offline, especially if there is no WiFi hotspot.

9 1 1 alarm service

CNET said that another less attractive use of old mobile phones is to "throw" them in the car storage box in case of emergency. Even if you don't buy a mobile phone service, you can still call 9 1 1 on your old mobile phone. Therefore, you should have another mobile phone at hand. If you can't find another mobile phone while driving on the road, this old mobile phone will become a lifeguard. However, before using a mobile phone without mobile phone service as a backup mobile phone in an emergency, there are several problems to pay attention to. To make a phone call, the mobile phone must be able to receive the cell phone signal. This means that if you are in a remote place or where there is no cell phone signal coverage, your cell phone can't make an alarm call. In addition, if you are disconnected during the call, the dispatcher can't call you back.
