如何将旧的Android设备变成酷炫有用的小工具（Internet Online entertainment)

你用旧的Android手机或平板电脑做什么？该问题通常会提示三个陈旧的答案。您可以将它们换来新的购买。或者您可以在eBay上转售它们。不过，可能您只是将它们装在抽屉中作为紧急备份。

但是，存在更好的选择，可以让您继续从老化的设备中获取价值。例如，您可以下载Google地图以创建专用的车载GPS导航器，也可以将其变成网络摄像头。

网络摄像头主题的多种变体可满足几乎所有现代监控，视频或音频应用程序的需求。例如，您可以轻松地将未使用的Android手机变成气象摄像头，婴儿监视器，petcam或nannycam。通过家庭网络流式传输图像是一个有趣的项目，几乎不需要花费额外的成本或技术技能。

您只需要一个现有的WiFi连接即可。当然，如果您的移动电话运营商有增加第二条线路的折扣计划，则可以将功能扩展到家庭或办公室WiFi范围之外。

更好的选择可能是将WiFi包添加到您的主要手机帐户。有时称为“ Jetpack”或“ Port-a-pack WiFi扩展器”的WiFi热点包（大约一副扑克牌的大小）可以在旅行时为行车记录仪或GPS提供网络连接。

请继续阅读，这些方案可以使您将旧手机或平板电脑更好地使用，而不是放在抽屉里。请记住，其中一些示例更适合未使用的智能手机，而另一些示例在平板电脑提供的较大查看屏幕上会更好地工作。

1.将旧的Android变成网络摄像头或行车记录仪

步骤1：建立退役电话的网络功能。

打开主页上的“设置”抽屉，然后浏览到“无线和网络”。然后选择打开WiFi。

如果为您的家庭网络配置了电话，电话将获得IP地址并连接。如果连接失败，请打开“ WiFi设置”，然后选择“添加WiFi网络”。然后输入网络详细信息，例如网络名称（称为SSID）和密码。与将笔记本电脑连接到网络时使用的信息相同。通过浏览到任何网页来测试连接。

第2步：从Google Play商店下载网络摄像头应用。

其中许多应用程序都可与PC客户端组件配合使用，该组件可安装网络摄像头驱动程序并连接计算机。其他应用程序具有高级功能，可让您将音频和图像发送到云存储点。对于初学者，请查看Pavel Khlebovich的免费IP网络摄像头，DroidCam无线网络摄像头，USB照相机和IP WebCam-Acid。

单击安装按钮，并允许该应用安装到您的设备。如果需要，请单击“设置”选项，或者在应用程序中按“启动服务器”或类似选项。摄像机视频图像将出现在手机上。

步骤3：在远程设备上配置查看媒体。

如果您只需要将图像保存到手机的存储器或将其上传到云，则可能无需执行此步骤。首先，在与电话连接到同一路由器的台式机或便携式计算机上打开Web浏览器。您在上一步中在电话上配置了此网络。笔记本电脑不必位于同一无线网络上。

接下来，在浏览器地址栏中输入手机的IP地址。通常，您在手机上安装的应用会告诉您地址是什么。它将类似于“ http://192.168.1.3:8080”。 “：8080”与端口有关。手机提供的图像和音频就像网站一样。

然后按笔记本电脑的Enter按钮。手机的网络摄像头服务器选项页面将显示在笔记本电脑上。

最后，如果您使用的是Chrome或Firefox，请选择“使用浏览器内置查看器”或类似选项。他们经过测试工作。如果使用其他Web浏览器查看相机图像，则可能必须进行试验。如果您使用的是其他浏览器，请选择“使用Java浏览器插件”并同意所有安全提示。您可能必须从结果链接安装Java插件。

步骤4：找到手机。

放置手机以获得最佳保护状态。例如，如果您打算将电话旋转式网络摄像头用作外部路径的安全设备，则窗玻璃具有良好的防风雨性。另一种选择是将摄像机内部指向窗口。请勿将相机对准太阳。尝试从背后获取光线以获得最佳图像。要保存手机的电池供长期使用，请选择电源插座附近的位置。

您可以使用汽车电话支架来制作用于内部放置的临时电话摄像头支架。使用吸盘将支架粘到窗户上。塑料L形支架便于将电话放置在无摄像头台式PC旁边。

要将行车记录仪手机固定在车辆中，您需要一个安装架，以将手机倾斜放置，以显示前方的道路。在线商店和实体商店的配件商店提供多种产品挡风玻璃和仪表板安装。

步骤5：设置电源功能。

将USB电源线从电话连接到墙上的插座，以便在家中或办公室固定使用。两年或更旧的手机可能会遭受电池老化的困扰-电池电量较少，并且会更快过期。因此，请勿长期使用电池供电。

要将旧手机用作行车记录仪，标准的自动吸盘线束会将手机牢固地固定在挡风玻璃上。您可以方便地将手机的自动充电电缆插入仪表板仪表板上有源的USB插座或点烟器。

步骤6：配置音频媒体。

对于某些计算机配置，此步骤可能是必需的。大多数网络摄像头应用程序都有一个设置选项，可使用浏览器播放音频。最后执行此步骤，以避免在电话和计算机之间距离太近时可能产生的反馈。

根据您的设备，您也许可以通过内置笔记本计算机麦克风或台式计算机中插入的附件麦克风来录制语音。如果您将旧手机或平板电脑用作车辆或其他地方的独立网络摄像头，请确保将音量设置为令人满意的水平。

2.将旧的Android变成独立的音乐播放器

此用途非常适合顽固的音乐爱好者和发烧友。通过这种方法，您可以将所有喜欢的音乐存储在旧手机的内存或Micro XD卡中。您不必担心昂贵的数据计划上限或流传输限制。

您可以通过插入或无线连接移动扬声器来绕开某些旧手机的细微，低质量的声音。如果您骑自行车或四处走走，耳塞耳机会是理想的解决方案。

如果将可充电电池组放在口袋中，则甚至电池电量也几乎是无限的。要在车上使用，只需插入手机的自动充电器即可。

您有两个选择。一种是离线使用电话。将您预先录制的音乐选择转移到空的microXD卡上，然后将其放入手机的隐藏槽中。或使用USB电缆将所需的音乐从计算机的存储设备加载到手机。

另一种选择是使用具有可行数据计划的旧手机（或平板电脑）。这使您可以连接到音频流站点。

当然，您可以将两个选项组合成更有用的第三种方法。这是完成转换的方法。真的很简单。

步骤1：回到出厂设置，将内存清除干净。

该过程因设备而略有不同。请遵循以下一般步骤：

转到设置>备份和重置。

选择恢复出厂设置。

确认重置操作。确保删除所有数据。

第2步：重新设置手机时要注意节省空间的选项，使其完全干净。

不要使用其他手机保存的备份。删除所有无关的应用程序。

步骤3：下载媒体应用。

如果您打算仅使用手机播放预先录制的音乐，则这是不必要的步骤。

否则，请转到Google Play商店并搜索媒体应用。确定您想要哪种音乐播放器。

例如，您要从流媒体应用程序中获取离线音乐吗？还是要从PC上存储本地文件？如果选择后者，请确保您具有用于收藏中音乐文件类型的音频播放器。

如果要进行音频流传输，请获取适合您需求的应用。所有音乐应用程序都不相同。

例如，一些流行的流媒体服务（例如Spotify和Google Play音乐）可让您下载以进行离线播放。如果使用它们，请记住在离开WiFi网络之前下载音乐以供离线收听。另外，请记住，某些服务（例如Spotify）会向您收取每月订阅费，以使用离线功能。

您无需为重新使用的音乐播放器设备支付数据连接费用。您可以使用家庭或办公室-或公共WiFi-下载您的选择供以后离线使用。

3.将旧的Android变成婴儿或门禁显示器

使用废弃的手机看家或在家里外的宝宝或门口。这是购买昂贵的监控摄像机并将其连接到网络的一种免费选择。

该过程与设置行车记录仪或网络摄像头的详细说明非常相似。唯一真正的区别是您用于运行视频监控的应用程序。除了几乎免费的费用外，优点是，只要Android手机通过WiFi连接，您就可以使用Internet连接从几乎任何地方调谐到音频/视频源。

您只需花一点钱，就可以加强技术，并将旧的智能手机或平板电脑用作视频门铃。该计划略微修改了上面详述的方法，但是其成本远低于专用的环形门铃系统。

手机或平板电脑留在室内，用作显示器。因此，您可以方便地支撑设备。您将需要安装室外iFi网络摄像头或智能门铃。 然后，您的旧手机或平板电脑将用作专用的视频监视器。

婴儿和门监控器工作所需的唯一其他操作是您决定使用的Android应用程序。 例如，Dormi专为婴儿监护而设计。 除了音频和视频监控之外，该应用程序还提供双向音频，因此您可以与远方的哭泣婴儿交谈。

Dormi应用程序可在任何距离工作，并使用任何可用的连接路由，例如WiFi或移动数据：Edge，3G，4G，HSPA +，LTE。 当无法通过WiFi Direct，HotSpot / AP访问Internet时，它甚至可以工作。 如果与子设备的连接丢失，则父设备将通知您。

门铃摄像头提供了广泛的功能，并可以连接到各种Android应用程序。 不过，您确实必须购买门摄像头。 首先购买相机。 然后将其与具有您所需功能的应用程序匹配。 您可以在旧的智能手机或平板电脑上运行该应用程序。

How to Turn an Old Android Device Into a Cool, Useful Gadget

What do you do with your old Android phones or tablets? That question usually prompts three tired answers. You might trade them in for a new purchase. Or you could resell them on eBay. Probably, though, you will just stuff them in a drawer as emergency backups.

Better options exist, however, that would let you continue to get value from your aging devices. For example, you could download Google maps to create a dedicated in-car GPS navigator, or you could turn them into webcams.

Numerous variations on the webcam theme address almost any modern day surveillance, video or audio application. For instance, you easily could turn your unused Android phone into a weathercam, baby monitor, petcam or nannycam. Streaming images over your home network is a fun project to set up and takes little in the way of extra cost or technical skills.

All you need is an existing WiFi connection. Of course, you can extend the functionality beyond your home or office WiFi range if your mobile phone carrier has a discount plan for adding a second line.

An even better option might be adding a WiFi pack to your primary mobile phone account. Sometimes called a "Jetpack" or "port-a-pack WiFi extender," such WiFi hot spot packs -- about the size of a deck of playing cards -- can provide an Internet connection for your dashcam or GPS when you travel.

Read on for some scenarios that will let you put your old phone or tablet to better use than as a dust magnet in a drawer. Keep in mind that some of these examples are better suited for an unused smartphone, while others would work better with the larger viewing screen a tablet provides.

1.Turn an old Android Into a Webcam or Dashcam

Step 1: Establish the retired phone's network functions.

Open the Settings drawer on the Home page and browse to Wireless and Networks. Then select Turn on WiFi.

The phone will obtain an IP address and connect if it is configured for your home network. If it fails to connect, open WiFi Settings and choose Add WiFi network. Then enter the network details like the network name -- called SSID -- and password. It's the same information you use to connect a laptop to the network. Test the connection by browsing to any Web page.

Step 2: Download a webcam app from the Google Play store.

Many of these apps work with a PC Client component that installs the webcam drivers and connects the computer. Other apps have advanced features that let you send audio and images to a cloud storage spot. For starters, check out Pavel Khlebovich's free IP Webcam, DroidCam Wireless Webcam, USB Camera and IP WebCam - Acid.

Click on the install button and allow the app to install to your device. Click the Setup option if required or press Start Server or similar option within the app. The camera video image will appear on the phone.

Step 3: Configure the viewing medium on your remote device.

This step may not be necessary if all you want is to save the images to the phone's storage or upload it to the cloud. First, open your Web browser on a desktop or laptop computer that is connected to the same router as the phone. You configured this network on the phone in the earlier step. The laptop does not have to be on the same wireless network.

Next, enter the IP address of the phone into the browser address bar. Usually, the app you installed on the phone will tell you what the address is. It will be something like "http://192.168.1.3:8080." The ":8080" is related to a port. The phone is serving the image and audio much like a website does.

Then press the laptop's Enter button. The phone's webcam server options page will display on the laptop.

Last, if you are using Chrome or Firefox, choose the Use Browser Built-In Viewer or similar option. They are tested to work. You may have to experiment if you use another Web browser to view your camera images. For instance, if you are using another browser, choose Use Java Browser Plugin and agree to any security prompts. You may have to install Java Plug-in from the resulting link.

Step 4: Locate the phone.

Position the phone for the best-protected view. If you are planning to use the phone-turned-webcam as a security device for an exterior pathway, for example, window panes afford good weatherproofing. Another option is to place the camera inside pointing at the window. Do not point the camera into the sun. Try to obtain light from behind for best images. To save the phone's battery supply for long-term use, choose a location near a power outlet.

You can use an automotive phone cradle to create a makeshift phone camera stand for interior placement. Use the suction cup to stick the holder to the window. Plastic L-shaped holders are convenient to place the phone next to a camera-less desktop PC.

To secure the dashcam phone in your vehicle, you need a mount to put the phone at an angle that displays the road ahead of you. Accessory outlets online and in brick-and-mortar stores offer a variety of products for both windshield and dashboard mounting.

Step 5: Set up power functions.

Connect a USB power cable from the phone to a wall outlet for stationary use at home or the office. Two-year-old and older phones can suffer from battery degradation -- the battery holds less charge and expires sooner. So do not rely on battery power for long-term camera use.

To use the old phone as a dashcam for your vehicle, a standard auto suction cup harness will hold the phone securely to the windshield. You can handily plug the phone's auto charging cable into the powered USB socket or cigarette lighter on the dashboard's instrument panel.

Step 6: Configure the audio medium.

This step might be necessary for some computer configurations. Most webcam apps have a settings option to play audio with the browser. Perform this step last to avoid potential feedback that can occur if a phone and computer are too close to each other.

Depending on your equipment, you might be able to record voice through the built-in laptop microphone or the accessory microphone plugged into the desktop computer. If you use the old phone or tablet as a standalone webcam in a vehicle or elsewhere, make sure the volume is set to a satisfactory level.

2. Turn an old Android Into a Standalone Music Player

This repurposing is ideal for die-hard music lovers and audiophiles. This approach lets you store all of your favorite music on the old phone's internal memory or micro XD card. You do not have to worry about a costly data plan caps or streaming limits.

You can bypass the tinny, low-quality sound of some older phones by plugging in or wirelessly connecting a mobile speaker. If you are cycling or walking around, earbuds are an ideal solution.

Even battery power can be nearly limitless if you stick a rechargeable battery pack in your pocket. For use in your vehicle, just plug in the phone's auto charger.

You have two options. One is to use the phone offline. Transfer your prerecorded music selections onto an empty microXD card and place it in the phone's hideaway slot. Or sideload the music you want from your computer's storage device to the phone using a USB cable.

The other option is to use the old phone -- or once again, a tablet -- with a viable data plan. This allows you to connect to audio streaming sites.

Of course, you could combine both options into a more useful third approach. Here is how to complete the conversion. It is really simple.

Step 1: Wipe the memory clean by going back to factory settings. The process varies slightly depending on the device. Follow this general procedure:

● Go to Settings > Backup & reset.

● Select Factory data reset.

● Confirm the reset action. Make sure to delete ALL data.

Step 2: Set up the phone again with space saving options in mind, making it completely clean.

Do not use a saved backup from a different phone. Remove any extraneous apps.

Step 3: Download media apps.

This is an unnecessary step if you plan to use the phone only to play your prerecorded music. Otherwise, go to Google Play Store and search for media apps. Decide what kind of music player you want.

For instance, do you want offline music from streaming apps? Or will you stockpile local files from your PC? If the latter is your choice, make sure you have audio players for the type of music files in your collection.

If you want to do audio streaming, get an app that suits your needs. All music apps are not the same.

For instance, some popular streaming services, such as Spotify and Google Play Music, let you download for offline playback. If you use them, remember to download music for offline listening before you leave the WiFi network. Also, remember that some services, like Spotify, charge you a monthly subscription to use the offline feature.

You do not have to pay for a data connection for your repurposed music player device. You can use your home or office -- or public WiFi -- to download your selections for offline use later.

3. Turn an Old Android Into a Baby or Door Monitor

Use your discarded phone to watch over your baby or a doorway entrance, either inside or outside your home. This is a no-cost alternative to buying expensive monitoring cameras and connecting them to a network.

The process is very similar to the detailed instructions for setting up a dashcam or webcam. The only real difference is the app you use to run your video monitoring. The advantage, beyond the mostly free cost, is that you can use the Internet connection to tune into the audio/video feeds from just about anywhere, as long as the Android phone is connected via WiFi.

For a slight monetary outlay, you can step up the technology and use the old smartphone or tablet as a video doorbell. This plan slightly modifies the approach detailed above, but it is far less costly than a dedicated Ring-type doorbell system.

The phone or tablet stays inside the house and serves as the monitor. So you can prop up the device conveniently. You will need to install an outdoor WiFi webcam or a smart doorbell. Your old phone or tablet then serves as a dedicated video monitor.

The only other things needed for the baby and door monitor jobs are the Android apps you decide to use. For instance, Dormi is designed expressly for baby monitoring. Besides both audio and video monitoring, the app offers two-way audio so you can talk to a crying baby from afar.

The Dormi app works at any distance and uses any available connection route, such as WiFi or mobile data: Edge, 3G, 4G, HSPA+, LTE. It even works when Internet is not available via WiFi Direct, HotSpot / AP). If the connection with the child device is lost, the parent device will notify you.

Doorbell cameras offer a wide range of features and connect to a variety of Android apps. You do have to purchase a door camera, though. Buy the camera first. Then match it to an app with the features that suit your needs. You can run the app on the old smartphone or tablet.
