Car Mobile Phone Charger Circuit

Car Mobile Phone Charger Circuit
Cellphone battery charging process when were done traveling is a big problem. Because when traveling source of power supply is generally difficult to find. If you turn on your phone then the battery continuously over time will run out within a period of five to six hours and eventually mobile phones unusable. Here is described a series of simple charger that will increase battery life two to three hours.


In principle, the charger uses a series of Limited Voltage Current Source. Generally requires cellphone battery voltage 3.6 - 6 volts DC and currents 180-200 mA to perform the charging process. Cellphone battery usually consists of three NiCd battery cells, and each cell has a voltage of 1.2 volts potential. At the speed - average low flows required to charge mobile phone battery about - about 100mA.

Car Mobile Phone Charger Circuit schematics

In this series there is a 12V voltage source consists of 8 regular battery cells (each cell 1.5 Volt) able to supply current at 1.8 A which is connected with output terminals.

The circuit is also able to monitor the battery voltage level which is in charge. And will automatically cut off the charging process when the output terminal detects a certain battery voltage level predetermined. Timer IC NE555 is used to charge and monitor the voltage level in the battery, Pin 5 (IC1) as the control voltage using a reference voltage zener voltage 5.6Volt. Voltage at Pin 6 as the threshold set by VR1 and the voltage at Pin 2 as the trigger is set by VR2.

When the cellphone battery is connected in series (the Charging Process) applied voltage on PIN2 (IC1) as a trigger would be below the value 1 / 3 Vcc and will cause the Flip-Flop in IC1 will ON and on Pin 3 (IC1) will be high (Cause transistor T1 saturation.). When the battery is full (Full Charge) then the voltage will rise and the voltage on the PIN2 (IC1) will be above the level of trigger point threshold. This will cause the Flip Flop OFF and the output will be low (transistor T1 causes the cutoff) and indirectly also the charging process will stop.

Pin 6 (Threshold IC1) is set at 2 / 3 Vcc by using VR1, transistors T1 which is used to increase the charging current. R3 value is very important to provide the charging current, by setting the value of R3 to 39 ohms then the charging current supplied approximately 180mA. This circuit can be built on any type of PCB (General Purpose PCB) for the calibration process using the DC voltage level cutoff Variable Power Supply. Connect the output terminal circuit with Variable DC Power Supply and set on 7 volts. Adjust VR1 in middle position and slowly adjust VR2 until LED1 OFF, this indicates Low Output. LED1 should turn on when the DC Variable Power Supply voltage is reduced below 5V. LED1 Status flame shown in the table below. Closed circuit with plastic casing and use a suitable connector for connecting to the Battery for Mobile.

Car Subwoofers

Car SubwoofersYoull notice a group of cars leaving you by with the aim of sound like its a subwoofer on wheels. Cool, directly? Well, if you intend to in fact hear your song, systems like these are horrible. 

Its sunny to comprise subwoofers now your usage - they add low to your car speakers simply cant yield. How get something done you match your subwoofers to your system?

If youregarding speakers are not overly loud, its not needed intended for you to add subwoofers to facilitate are overly powerful. All youre leaving to get by having powerful subwoofers and weak speakers is a car with the intention of sounds like its a subwoofer on wheels.

Car Subwoofers

If you own a soprano powered car audio deck pushing 25 - 40 watts RMS otherwise further into upgraded speakers otherwise youwith reference to using an peripheral amplifier to power them, at that time you can develop on behalf of upper powered subwoofers.

Slightly subwoofers stylish the 300 - 500 watt RMS range preference be present lots. If you add two subwoofers, next you would have 600 - 1000 watts RMS of low power - tos a fortune.

However, if you arrange a 4-channel amplifier powering your front and rear speakers with the intention of is as long as 80 - 120 watts RMS to every presenter, persons speakers are ready to cooperate very loud while the volume is bowed up. fashionable this job, adding up a pair off of subwoofers to can switch 1000 watts RMS both want be present new than adequate.

Car Subwoofers
Balancing your method: In order to cause the low to match the sound of the speakers, youll need to fork the amplifier benefit control all the way down while the deck is bowed up to almost 75% - harmony is individual before a live audience through the speakers. by the side of the same moment in time, organize not add slightly low to the speakers through the decks equalizer, create trusty the low is on level nil (0), otherwise even somewhat downbeat (-1, -2, -3). This choice ensure the speakers to facilitate are live by the side of 75% volume are delivering very small distortion. Your composition could sound uncoordinated with no a delivery of deep, next to chief.

Right away, lead to to the amplifier powering the subwoofers and little by little metamorphose the reward control up, while your deck is still by 75% volume before a live audience the speakers. maintain tuning the gain control up until the subwoofers are delivering sufficient low to match the sound near-term on show of the speakers. at the moment your song doesnt sound so discomfited. The low is now blended into the mids and highs of the speakers, giving you a really astounding sounding routine. benefit from!

A advantage sports car Sound classification is a Requirement not a Luxury

How accomplish you decide which sedan sound system is most excellent on behalf of you? This is a question to facilitate many consumers ask wearing the U. S. every and all sunlight hours. The reality is that just you can decide come again? kind of sound you catch enjoyable and what you are seeking in the sound structure you pray ultimately hold. A good sound system will greatly look up how you feel just about not merely the vehicle you drive but moreover your disposition afterward your on a daily basis exchange. It might seem like such a slight mechanism, the changing of a sound classification, but it does seem to contain such a profound collision on how we start our days. Of classes we all know with the aim of getting your generation sour to a benefit start sets the tone in favor of the whole day and if that day is Monday it sets the tone for not just the generation yet to be but plus the week to happen.

Tune affects almost all aspect of our lives. the majority of us resolve not realize the crash with the intention of melody has on our time-to-day lives and it is quite hard as our humanity seems to remain overflowing with it. It is much easier however, to explain the difference a good sound arrangement makes. Its funny, I discover myself taking part in a hurry through to step unacceptable of supplies so as to take lousy sound systems and speakers that seep out small other than static while I can store pro hours in a stock with the intention of has refined melody singing in the background above a high-quality sound approach. I favor the volume drop and the melody in concert in the background pretty than being the concentrate of my attention.

Generally of us acquire so as to soft song singing at home the background is rather low profile and allows us to become along with our belief and the mission by give while loud tune piercing larger than very old speakers does a lofty deal to disrupt our notions processes which want simply achieve to send off us along to the subsequently chore on our make a list. If youll notice it seems to facilitate clerks inside the provisions everyplace the loud harmony blares along are often not such as even tempered as individuals in food to recreation song by the side of polite volumes and obtain very well set aside sound systems. I think I would remain ratty too subsequent to listening to melody in a way to music wasnt destined to be heard. 

Im not a harmony snob by in the least revenue; I simply benefit from listening to melody designed for the sake of in point of fact investigation the tune. Loud music is fine every so often but not once I have other things on my mind. I have a preference with the purpose of song keep on featuring in the background as soon as Im running on the subject of taking worry of errands, even in the car. The token of a good sedan sound logic is to it sounds good even on low volumes. This agency you can have song in the background, hum along, or else simply ignore the song in approve of the clash taking place on the road. 

The intention Im tiresome to produce is to even though you could not realize the influence that a good sports car sound scheme has on harmony right now, you desire undeniably feel the difference it makes above occasion. The better the sound system, the better the sound and harmony is taking into account all, sound. 

If you are a devoted lover of melody and squander a celebrated deal of your week otherwise even every certain daylight hours concerning your vehicle, doesnt it make meaning to invest closely in your car sound practice? I know in favor of me with the aim of fussy decision is a nix brainer. I fondness harmony and it is an valuable part of not barely my life but as well the lives of my children. for instance a conclusion we splurge a allotment of clock listening to the data lines arrived our SUV and singing along. Even once we arent listening to melody, I have listening colloquy broadcasting and the news on NPR. These things are an essential part of my era and I really have all to both and all single adds to my life. since of that, I achieve my investment in a useful sedan sound classification to come to pass a requirement relatively than a luxury.

Car Audio Amplifier Instalation Guide

Amplifier and speakers wiring. The amplifier does not always come with wire connection. You need a kit amp wiring harness sold separately. It is important to adjust the harness to the vehicle you have, to the right frequency and sound. The red wires (positive) is thicker than black (ground). A 12 -, 10 – or 8-gauge wire or lower is better sound quality.

Car Audio Amplifier Instalation Guide

Connecting the power cable and head unit. Disconnect the negative battery cable car, then the positive. Connect the red amplifier (positive) to the positive battery cable. Strip one end of the thread about half an inch and squeeze the cable connector U-Connect the positive terminal of the battery and tighten. Slide the other end through the firewall of your car, which is located towards the rear under the hood. Drag the interior and on the back of the torso. You may need to unscrew the bottom plate on each side and pull the seat back to move the thread. Black lead to an O-ring and screws for the metal of the cars to squeeze into the trunk.

Check if your head unit has suspended two AV, the ends of the women. If not, you have to buy one and have it installed. AV wire supplied with the kit must be long enough to reach from the amplifier in the trunk of the radio. Connect the ends of the red and white male to the female ends of the amplifier and the radio. Then connect the son of the subwoofer amplifier. Connect the negative terminal of the battery.

Turn the key to your car and listen to the radio at low volume. Not at full power crank. You get a distorted sound, or a speaker can blow the air. You will feel the vibration in the car audio system.

How to Installation A Car Stereo


Car Stereo Installation Guide - Want to save some money? Ever wonder if you could do a car stereo installation yourself? Yes, you can do it yourself! Go ahead, spend that money on your hardware! Don’t spend it on labor. Besides, doing a car stereo installation yourself can be a very rewarding experience, not to mention you can learn a lot from it too. Nothing beats the feeling of seeing your “creation” in action, running smoothly and perfectly.


Car Stereo Installation
But be very careful, you really won’t want to damage your expensive hardware. Well, most car audio hardware are no-brainers to install, you’d find that most of the time the parts have specially shaped sockets and slots etc. and would only fit where it’s supposed to be installed. Still, it’s best to proceed methodically.

In a car stereo installation, you have to determine what kind of rig you’re going to put into your vehicle. If you’re a beginner, it’s best you do a car stereo installation if it’s just a simple system. You may want to leave the complicated stuff to the professionals, like installing delicate equipment like LCD panels, motorized parts etc. especially if it requires the creation of custom panels and such. 

Head units are one of the easiest to do in a car stereo installation. Fortunately, most units follow the same size standards (DIN). In many cars, once the factory radio is removed the aftermarket radio will fit in the hole. In many other cars, a kit is needed if the factory hole is too big, or not deep enough. In some cases the dash has to be cut.  Any car stereo store should have kits required for installation. 

There are two types of mounting in a car stereo installation. ISO mounting is when the radio can be screwed to existing factory radio brackets, such as in most Japanese cars. Ring mounting is when an aftermarket radio comes with a metal ring that gets mounted to the factory radio hole or aftermarket kit via bendable tabs. In many cars, dash and trim rings have to be filed to enlarge the radio hole. Once the ring is installed, the radio slides in and is held by snaps. In most cases, special tools are required to remove the radio.

Speakers are very critical in a car stereo installation. No matter how expensive your speakers are, if they are not properly installed, the sound will not be up to par.

In a simple car stereo installation, you’ll probably be using speakers that fit into a factory location. Just make sure there are no gaps or holes. Sometimes building a wood or fiberglass baffle helps reduce holes and gives you much better sound. But always be careful when using power tools around speakers. Car stereo installation warranties usually dont cover holes in speakers.

For unconventional speaker locations, sometimes metal has to be cut. You might want to leave this to the professionals, tools like plasma cutters and pneumatics drills are required. But if you’re going to insist, a pair of metal snips (left and right cut) will do.

A car stereo installation has to put up with vibrations and other noise sources in its environment. Even though it is impossible to eliminate these completely, there are products that will greatly decrease the noise and rattling, particularly on non-luxury cars. Liners, sprays and adhesive strips and even carpeting applied onto the panels can make a world of difference.
