if you have a cell phone that has a GPS on it


Most people are in great pains when they have the feelings of becoming the victim of cheating.
Be careful to go on for only professional sim car spies because there are some that are not worth your penny. Also, be careful to only use this technology for people that are subject or close to

you. The law really frowns at people who breach other peoples privacy.What good will a cell phone GPS locator do for you? You may be wondering why most smart phones today come with navigation

systems and all that. Well, it is simple, it both keeps you on track as well as it helps loved ones to know where you are at any given time. For instance, if you find yourself in a tight corner and

you cannot tell how you got there, if you have a cell phone that has a GPS on it, you can retrace your footsteps and get back on track in no time rather than going round in circles. Also, if at all

you delay and cant get home when you should, your family and friends will be able to know where you are and therefore will not worry so much.
Accessible entirely from the comfort of your own computer, cell phone spy software makes keeping tabs on your loved one simple. Installation is relatively easy as well-all you need to do is create

an information account online through their website, follow the directions, and reboot the phone. In most cases it only takes a few minutes. Once installed, youll be able to monitor the phone

immediately. There is no limit as to how much you can use the software, and there is no need for upgrades or reinstallations.
You can learn more about how to catch cheating girlfriend by reading up on reviews. These, for example, can tell you if the software in question is compatible with Blackberry phones, iPhones,

Symbian S60, Nokia, Windows Mobile, smartphones, and other mobiles on the market today. The more versatile, the better-it means that you can install the software on more than one phone. This makes

it so that if your girlfriend uses a spare, you can still see what shes up to.
Well not anymore! You can use cell phone tracking software to find out EXACTLY what she is saying to everyone she sends a text to, and shell never even know youre watching her. She wont even

know the software is installed on her phone, because it is virtually undetectable. She wont see that its installed. She wont even see that its running. And it will send all of the information

stored in her phone to a remote server, without making any noise or alerting her that its doing it.

Cell Phone Controlled Audio Video Mute Switch

This cell-phone-controlled audio/ video mute switch is highly useful in automobiles. The circuit automatically disconnects power supply to the audio/video system whenever the mobile handset is lifted off the holder for making or receiving a call. You can use any readily available cell-phone holder with some mi-nor alterations or fabricate it yourself as shown in Fig. 1.

The circuit is wired around IC LM555 (IC1), the CMOS version of timer NE555, as shown in Fig. 2. IC1 is used as a medium current line driver with either an inverting or non-inverting output. It can sink (or source) current of up to 50 mA only, so take care while handling it. The audio/video system is connected to the circuit via normally opened (N/O) contacts of the relay.

When the cell phone is in its holder, LDR1 does not receive any light from white LED1 and its resistance is high. As a result, the voltage at pin 2 of IC1 re-mains high to provide a low output at pin 3. The low output of IC1 activates relay RL1 and the audio/video system gets power supply via its N/O contacts. LED3 glows to indicate that the audio/video system is ‘on.’  When the handset is taken off the holder, light rays from LED1 fall on LDR1 and its resistance decreases. 
 
As a result, the voltage at pin 2 of IC1 de-creases to provide a high output at its pin 3. The high output of IC1 deactivates relay RL1 and the audio/video system does not get power supply. LED2 glows to indicate that the audio/video system is ‘off.’   Preset VR1 is used to control the sensitivity of the circuit. Zener diode ZD1 is used for protecting white LED1 from the higher voltage. The circuit works off a 12V car battery. Switch S1 can be used to manually switch on/off the audio/video system.
