Non-phone Uses Of Mobile Phones

In my previous article I described some useful things one can do with mobile phone

, like remote access to a PC, remote printing, video projector and audio output for mobile phones, using mobile phone as a WiFi hotspot and as a pocket fax machine. Since then I have found some more useful tips, some of which seem to me so useful that I want to share them with everyone.

Phone emergency charger. Most phone chargers have an output voltage in the range of 4 - 5 Volts. This is the same as the voltage of three AA or AAA type batteries. One can just use a small flashlight with three AA or AAA batteries to make a portable charger. You will need an old charger or a USB charging cable, if one is available for your phone model, cut off the cable jack and solder the cable to the contact leads in the flashlight. Notice that bigger D or C type batteries have a much larger capacity, so using them you could charge your phone much better. However a flashlight with such batteries is much bigger and not so convenient to carry, besides it is more difficult to find such a flashlight and batteries.

Flashlight. As you have seen, one can make a phone charger out of a flashlight. But you can also use your phone as a flashlight. It is sufficient to open an application that makes the biggest part of the screen white (for example, messaging). There are also many freeware applications that make the screen totally white and shining at maximal possible brightness. Such applications can be easily found on the Web.

Storage device. Yes, as most mobile phones have a memory card (SD, MMC, Memory Stick Duo), one can use them just like a flash disk. Most laptops can read storage cards directly, so one just needs to take the card out of the phone and insert it in the laptop to copy the data. For desktop PCs one can use a card reader, which is not bigger than a typical flash disk. It is also possible to connect a phone to computer using a special cable or Bluetooth but most phones require a driver to be installed on the PC.

Webcam. Almost every mobile phone now has a built in camera, so one can just use the phone as a webcam. There are some PC applications that turn mobile phone into a webcam (for example, Mobiola). Some applications, for example Qik, do not even require a computer, they use the phone's Internet connection to stream the video.

Voice recording. Any mobile phone has everything needed to be used as a voice recording device. One can record phone conversations or use it just to make quick voice notes. Voice recording is available in many phones, however it is often not easy to reach it, which makes it impossible to start recording quickly. That is why it may be better to use one-button recording applications like Resco Audio Recorder.
