Modern mobile phone update super fast, whenever a new model appears, it is the time for many people to change their mobile phones! When a new mobile phone arrives, what is the use of the old one? It's a pity to sell second-hand goods. Today, I'd like to recommend some smart ways to use old mobile phones, so that "former partners" can continue to play their waste heat!
1. Car navigation
One navigation is the cheapest and it costs hundreds of yuan. If there is an old mobile phone with a 3.5 inch screen and GPS function, as long as you buy a car holder and cigarette lighter power plug, you can have a vehicle navigation instrument for tens of yuan.
Install mainstream free navigation map applications on mobile phones, such as Baidu map, Gaode map, etc., as long as offline maps are downloaded in advance, even if you don't surf the Internet, you can help you navigate accurately.
2. Trip recorder
For the car family, the most annoying is to encounter accident disputes, and the driving recorder can record the images of the driving process truly, so that when an accident occurs, it will not be wronged.
It's just that there are thousands of car recorders in the market, but it only costs tens of yuan to transform the old mobile phone. It can be said that the difference is very big ~ in the old mobile phone, you can use the car recorder app by downloading the vehicle mounted bracket and connecting the power supply. It has powerful functions and can support cyclic video recording and power on automatic video recording, which is not much different from special vehicle recorder.
3. Home monitor
Home cloud monitoring equipment can be used to monitor the situation of the home, check children and pets, and prevent accidents.
However, a cloud monitoring device is not cheap. If you happen to have an idle smart phone, you can achieve remote monitoring through it. As long as you download the monitoring software on your mobile phone and connect it to the screen of another mobile phone through WiFi, the old mobile phone can be used as a monitor at home. Body in the distance, home state can also have a panoramic view!
4. Universal remote control
TV, fan, air conditioner and other electrical appliances all need remote control. If you don't want to worry about a lot of remote controls, and the old mobile phone just has the function of infrared emission, you can turn it into a universal remote control to control large and small appliances.
For example, "remote control Wizard" application can achieve this function. After downloading the software, first find the product model of the remote control device (common household appliances are available), and then through the "learning" program, let the mobile phone learn to control home appliances. If not at home, you can also achieve remote control.
5. Document scanner
Scanning text into a computer for editing can save a lot of typing time, but what if there is no scanner? Is it useless? NO！ As long as there are mobile phones that can take pictures, this problem can be solved.
Download docscan, scan all-round King mobile app, you can convert the screen into text. If you usually have a large number of files to handle, let the old mobile phone become an office assistant!
6. Mobile phone to camera
Although the pixel of mobile phone has been improving and the effect of taking photos is good, it is still far from the SLR camera. However, usually carrying a single eye is very cumbersome, so can the old mobile phone change into monocular?
It's not difficult to turn a mobile phone into a SLR. Just add an adapter and install a SLR Lens. You can have a simple version of the monocular camera immediately. It's much lighter, but the effect of taking pictures will never let you down.
You don't need it, but you can also give it to your family. You can go out and play, so that children can record wonderful moments!
7. Burglar alarm
Although the public security in most areas is good, there are also many people who are stealing and singing. Installing a warning device in the indoor / car is equal to a layer of security. The old phone can be realized by a little modification.
The self-made mobile phone anti-theft alarm system consists of infrared detector, mobile phone number confirmation circuit and dial-up circuit. First, the mobile phone number is stored in the modified mobile phone. When there are bad people entering or the car is started, the system will call the input phone number in real time to remind you to take preventive measures.
8. File memory
Music, movies, games Which are reluctant to delete, but the mobile phone storage space lights up the alarm, what should we do? At this time, old mobile phones can come in handy.
Nowadays, the mobile phone usually comes with 8gb-32g of built-in storage, which can not only save files, such as songs / movies / games, but also be used in real time (watching TV, playing games...) , is it more practical than the mobile hard disk? Of course, if you think your own memory is not enough, you can also install a memory expansion card.
In addition to the above methods, you can also use the old mobile phone as an alarm clock, flashlight, audio and video player. In fact, the old mobile phone is more valuable than we think!
