If you are one of the many people across the country considering a new auto sound system, there is a great deal of good news. First of all, it is very possible to find a good bargain on a nice sound system for your car, truck, or SUV if you are willing to shop online and install the system yourself. The problem often lies not in the cost of the system but the price of the installation. However, the cost of installation is well worth the dollar amount for many of us who really have no clue what to do as far as a project of that scope goes. I for one am among the electronically challenged and not really willing to risk my dash board for an experiment in frustration and failed electronics. That being said, there are many who are either perfectly and wonderfully capable of installing a nice auto sound system or are fortunate enough to know someone or someone who knows someone who is. Gaining Up, finding a great bargain online is probably the best way to go-provided you've actually been...

Finding auto sound systems that can keep up with the constantly evolving technology of today is a real challenge for many car and sound enthusiasts not only around the nation but also around the world. There was a time in the not so distant past when car stereos that had CD players or CD disc changers where the cutting edge of technology. New technology however has nearly rendered the CD players in cars as obsolete as long forgotten 8-track players. The sad news is that many carmakers are clinging to the old days and only offer something as modern as cassette players as standard equipment for auto sound systems. I think those days will soon be forgotten, as cassettes are no longer even in mainstream production. You should also find that as CDs are rapidly becoming replaced by MP3s that take up very little space in our cars and homes, one day very soon we may see that music companies have decided it is no longer cost effective to produce CDs and render all music to digital formats. So, ...

In operation, the alarm circuit allows a 0 - 47 second time delay, as determined by the R1 /C1 combination, after the switch is armed to allow the vehicle's motion sensor to settle down. This allows you time to get a bag of groceries out of the trunk and not have the hassle of juggling the groceries and the key switch at once. During the time delay, half of LED1, which is actually a single, bi-colored, three-legged common cathode device, lights green. At the same time, pins 8 and 4 of U2 (a 555 oscillator/timer) are held low by Ul (a 3905 oscillator/timer), causing the alarm to remain silent. Once the delay is over, LED1 turns red, indicating that the circuit is armed. Auto Alarm Schematic Circuit Diagram At that point, a ground at pin 2 of U2 forces pin 3 of U2 high, closing the contacts of Kl and sounding the siren for a time duration determined by R4 and C2. Once the time has elapsed, pin 3 is pulled low, Kl opens, and the circuit is again ready to go. The circuit can be manuall...

If you've been shopping lately for an auto sound system then I am fairly certain that you've come across several full entertainment systems among those in the running for your audio and entertainment dollars. Vehicles today offer everything from DVD players, individual speakers, headphones (also individually adjustable), and even dual players that will allow one different audio to be played in one section of the vehicle than another.
