Car Security Alarms
Have you ever wondered how your car security alarm works? Contrary to what you might think, car alarms are actually pretty simple devices ? they're just a set of sensors connected to a siren.
A car security alarm typically has six parts ? a siren (the device responsible for making the noise) and five sensors (window, door, pressure s, shock, motion and tilt sensors).
The simplest car security alarms work mechanically ? if someone tries to force the door open, for example, the car door sensor sends a signal to the siren, which in turn makes loud sounds. The technology behind door sensors is actually the same technology used in your refrigerator. Notice how your refrigerator lights turn on when you open the door and turns off when you close it? Both technologies are actually simple circuit systems ? when someone forces the car door open, the spring pushes the button open and closes the circuit, sending electricity the alarm and siren.
Most car security alarms systems have very useful accessories such as a radio receiver for wireless control from a key, and backup batteries that allow alarms to work even when the main power source gives up. Most car security alarms have sirens that are capable of creating distinct sounds so that the owner can pick out a sound pattern and be able to tell if it is his or her car that's sounding an alarm.
The most recently developed car alarms offer features that promise to deter car theft more effectively. Among these new features are small computers that are designed to outsmart thieves. When an intruder cuts off the main power source of the car alarm system to prevent it from sounding off, the computer (powered by a hidden battery) triggers the siren to sound the alarm.

Old Time Radio on your MP3 Player
For those of us that are fans of Old Time Radio (OTR), until recently there were very few options to listen to these classic programs. To listen to them, you would have to use a PC or laptop. This was not very portable or convenient. Personally, I like to listen to the shows at night before I go to sleep, but my computer is nowhere near my bedroom.With the recent proliferation of CD and memory based MP3 players, a new option has emerged to listen to our favorite classical radio programs. These tiny devices can not only be used to listen to music, but can now be used to listen to Old Time Radio shows.
As many of the OTR shows are recorded at low bit rates and frequencies, you can typically load several hundred hours of shows onto a single CD. If you are using a memory based MP3 player, even a 64 mb player will hold several half-hour shows.Of course, not everything is perfect with OTR shows. As I mentioned earlier, because of the age of these programs (poor recording quality, mono...
