If you've ever shopped for a new lens for a Canon camera and wondered what some of the letters and numbers on the lens mean, you're not alone. Canon lenses vary widely in price by their performance, and understanding the lens designations can help you decide which lens to buy. One common designation on Canon lenses is USM.
What Is It?
USM stands for ultrasonic motor. A USM lens has a small motor in the lens that assists with autofocus, making the lens focus faster.
Types
Canon actually has two types of USM lens: ring USM lenses and micromotor USM lenses. The two differ substantially in performance and price. Ring USM motors are much quieter and allow for on-the-fly manual focus. Micromotor USM lenses do not allow for manual focus when the camera is in auto-focus mode.
Identification
Both micromotor and ring USM lenses have the USM designation on them, but the specific type is not designated. Check the Canon website or lens catalog and read the specifications to find out.
Performance
Generally, Canon lenses carrying the "L" designation have ring USM. These lenses have a red stripe around the end of the lens. Most of the Canon lenses that have fixed low apertures of f/2.8 also have the ring USM.
Cost
Ring USM lenses are more expensive than micromotor USM lenses, which in turn are more expensive than non-motorized lenses.
Projection TVs are challenging to move because they are extremely heavy and can be permanently damaged if dropped. More importantly, projection TVs contain delicate equipment that is invariably thrown out of alignment when they are moved. Fortunately, projection TVs can be recalibrated fairly easily. Prepare properly before you move your projection TV and work in stages to avoid damage.
Instructions
1. Turn off the TV and unplug it from the wall. Secure the cord by taping it to the back of the TV, or use your TV's snap-on holders.
2. Wrap the TV in blankets or padded comforters to protect the screen from cracks and scratches. Secure the padding to the TV with duct tape so it won't slip off.
3. With the help of at least one other person, lift the TV straight up and carefully carry it to the moving van. Make sure the TV remains upright and level for the entire process; do not turn the TV on its side or back. The steadier you can keep the TV, the better.
4. Place the projection TV in the moving van against a wall. Use bungee cords to secure the TV to the side of the van. The bungee cords should be firm so that the TV doesn't shift or rattle in transit.
5. Fill the space between the TV and any other objects in the van with pillows and soft objects.
Zinc is often used as a protective layer on iron and steel products.
Zinc carbonate (ZnCO3), normally referred to as smithsonite, is an ore that contains the metal zinc. It was named after the English scientist James Smithson (who dedicated his fortune to create the Smithsonian museum in Washington, D.C.). The mineral has a number of uses in health care, metallurgy, electronics, and construction.
History
Before Robert Smithson, miners experienced a great deal of confusion about an ore known as calamine. Certain varieties of calamine could produce zinc, while others that appeared identical could not. Smithson discovered calamine actually consisted of two distinct substances: zinc carbonate (smithsonite), a good source for zinc, and zinc silicate (hemimorphite), a bad source of zinc. This discovery not only was of great benefit to miners, but his experiment brought together the sciences of chemistry and mineralogy which were mostly separate disciplines in the 19th Century.
Zinc
The most important use of zinc carbonate is the zinc metal that can be extracted from the ore. Zinc is a blue-gray, metallic element, resistant to air and water corrosion and a good conductor of electricity. It is often used as a protective layer on iron and steel products to prevent them from rusting. As an alloy, it can be used for paint, chemical, and agricultural applications. It is also found in dry cell batteries, TV screens and fluorescent lights. Major refiners of zinc include the United States, Canada, Australia, Mexico, and Peru.
Jewelry
Smithsonite itself is often used ornamentally. When polished into a gemstone, it displays a blue to green globular habit with a feathery luster. Copper impurities often enhance the attractiveness of the mineral. When sold as a jewel, vendors often refer to smithsonite as "Bonamite." Bonamite is sometimes misrepresented as jade. Real jade bears no relation to smithsonite.
Health
Zinc itself is an essential mineral for all human and animal life. It allows the body to process food and nutrients as well as supports the functioning of key enzymes. Zinc also is necessary for sexual maturation as well as skin and bone growth. Additionally, zinc carbonate plays a significant role in Chinese medicine. Smithsonite often may be used to treat problems with the stomach and liver. The mineral should not be taken internally, and the type and quantity of its usage should be determined by an experienced practitioner. Although there are no known drug interactions with smithsonite, its safety has not yet been evaluated by leading herbal medicine organizations.

The built-in flash on a digital camera rarely provides enough light or enough versatility for the dedicated digital photographer. For this reason, many digital photographers choose to use a flash unit for their digital camera. Flash units come in many shapes and sizes, and must precisely match the digital camera.
Instructions
1. Check to see whether your digital camera has a "hot shoe." A hot shoe is a jack on your digital camera that connects your camera with an external flash unit. If it does have a hot shoe, you will find it easier to choose a flash unit for your digital camera. Newer digital cameras may even have a wireless hot shoe, which you can use with a wireless flash unit.
2. Identify flash units that are compatible with your camera. Choose the one that most suits your needs and budget.
3. Read the manual included with your flash unit to learn connect the unit to your digital camera.
4. Connect the flash unit to your digital camera and take pictures.

Scala is a general purpose programming language that is created to transform standard programming patterns in a precise, polished and type-safe manner. Java, on the other hand, is a programming language that runs the latest programs including business applications, games and utilities. Scala and Java can work in the same environment because both languages run on Java Virtual Machine (JVM). Since Java and Scala are fully compatible and interoperable with each other, either program can be used as a substitute for the other depending on the project requirements of the coder. Scala is not a superset of Java, but it is rather a worthy alternative for every Web coder to enjoy.
Instructions
1. Download and install the current version of Scala for your environment. Scala is supported by various operating systems, such as Windows, Unix, Macintosh and Cygwin.
2. Type an expression to start using the Scala code interpreter, which is Scala's interactive "shell" for authoring expressions and programs. Here is an example:
$ scala
This is an interpreter for Scala.
Type in expressions to have them evaluated.
Type :help for more information.
scala>
When you type an expression and hit "Enter" or "Return," Scala interprets it like this: "scala> 1 + 2"
Then the interpreter will print: "unnamed0: Int = 3"
This line of code is comprised of an "automatically designated or user-defined name to refer to the calculated value (unnamed0)," "a colon (:)," "the type of the expression and its output (Int)," "an equals sign (=)" and "the value derived from evaluating the expression (3)"
3. Enter a val definition to see how Scala functions. Scala's method of differentiation is applied between vals, which are variables that are designated once and never change, and vars, which are variables that may be changed or modified over their lifetime. Here is a sample of a val definition:
scala> val msg = "Hello, world!"
msg: java.lang.String = Hello, world!
This val definition designates "msg" as a name for the value "Hello world!" If you are familiar with Java, you may notice that the type of value used here is java.lang.String. As mentioned earlier, Scala and Java are interoperable with each other, so in this instance, Scala strings are likewise Java strings. In reality, every Java class is also found in Scala.
4. Enter the ":quit command" if you are still running the Scala interpreter and save your code into a file named hello.scala. Here is how you do that:
println("Hello, world, from a script!")
Then run the code by typing: ">scala hello.scala"
Scala should respond to you with a greeting: "Hello, world, from a script!"
Noticeably, most of the codes used in this project are derived from the Java language, so this proves that Java is really well-integrated with Scala. Scala and Java will always work hand-in-hand and one can't be without the other.

You need an 8mm film projector to play an 8mm home movie.
Long before digital video cameras were available to the regular consumer, home movies were shot using 8mm film cameras. To save the deteriorating footage from these films mostly coming from this generation's parents and grandparents, and to better archive them as well, you should transfer them in digital format as soon as possible. To do so, you can either go to a professional video facility or make a do-it-yourself transfer to save money. All equipment required for a non-professional transfer is relatively easy to find.
8mm Film Projector
An 8mm film projector is the primary requirement for transferring 8mm home movies to digital format. Such projectors are usually sold at goodwill stores, online stores and vintage camera stores.
The projector serves as the player for the source footage intended for transfer. Although a projector with a feature called variable-speed adjustment is an ideal choice, any functional 8mm film projector may do. However, access to variable-speed adjustment is beneficial to minimize the flicker effect caused by the frame rate difference between the source footage from the film and that of the digital camera taking the video of the projected film.
Video Camera
Any functional video camera can be used to shoot the projected film from the 8mm film projector. However, to capture the best image quality, it is best to use a high-definition (HD) camera. It is also important that the camera has enough number of tapes or disk space to accommodate the amount of footage for transfer. Moreover, plugging the camera to an electric outlet instead of using the camera battery provides better peace of mind during the actual recording. This avoids draining the camera battery from prolonged use.
Tripod and a Flat, Stable Surface
When setting up the video camera for recording, you should place it just at the right distance and angle in order to acquire the best footage from the film. It is important to secure the area to avoid accidentally bumping the tripod or the camera during the recording. At the same time, you should also place the 8mm film projector at a proper distance and angle from the projection wall in order to get the best possible footage from the film source. The area where to place the projector must be a flat, stable surface as well.
Computer With Video-editing Software
After capturing the footage from the projection wall, you must connect the camera to the computer via a USB, FireWire or RCA cable to transfer the video files. Depending on the camera used, the footage may already be in digital format (if you're using a camera with tapeless recording) or it may still require the process called "capturing" or "digitizing" (if you're using a camera that still requires recording with a tape).
During the digitizing process, the video-editing software captures the footage in real time to convert the video into digital files. After the transfer, the footage can already be played, edited, burned in a DVD or simply archived in an external hard drive.

Photographers know that conditions determine film type. Photographers choose a fast film, one that rapidly captures the image, for motion shots, such as a sporting event. Slow film types are used with landscapes or in low lighting to capture the full range of color and depth. Although film type is important, proper exposure is the key to good photography.
Instructions
1. Decide upon using slide film (positive) or print film (negative). A slide film requires more skill as it demands precise exposure times. Negative film is the most common film type and is available anywhere. Slide film is best if the final image is going to be digitized.
2. Choose between black-and-white and color film. Photographers use black-and-white film to provide an artistic flare to their images. Black-and-white film is also used by beginning photography students to teach contrast and dark room techniques.
3. Decide upon film speeds. Film speed is indicated with an ISO number. ISO 100 is the slowest speed and has the finest grain. ISO 100 should be used on bright sunny days. Slower film speed provides a full array of color and gives a photograph deeper tones and shades.
4. Choose ISO 200 and shoot under a range of conditions. ISO 200 is a very good general use film. It allows for slower shutter speeds and is the single most common film. This film also takes into account slower lenses such as a zoom lens.
5. Select ISO 400 and photograph with faster shutter speeds. This film is used most often for action shots with lower levels of light. The faster film captures the image but also sacrifices some of the clarity of slower film.
6. Use ISO 800 or 1000 in low light levels. These film speeds are also very good at capturing quickly moving objects. Use ISO 800 or 1000 for fast action events like racing and skiing, or at sunset and sunrise. The graininess of these films can be used by the photographer to provide an additional artistic layer to a photograph.

Infrared photographs show longer wavelengths of light than the human eye can normally see.
The Hoya R72 infrared filter passes light that is 720 nanometers (nm) or longer and blocks the shorter, visible wavelengths. However, the light allowed to pass by this filter is invisible to the human eye and to the Nikon D40 digital camera unless the anti-aliasing filter is removed. Removing the anti-aliasing filter allows the D40 to record light ranging from about 400 to 1,000 nm. With the anti-aliasing filter removed, a Hoya R72 filter attached to the camera lens will block all light shorter than 720 nm and allow the camera to capture the longer infrared wavelengths.
Instructions
1. Remove the two screws from the underside of the lens mount and the six screws from the bottom of the camera body. Do not remove the screw located within the battery compartment, under the rubber flap found along the outside edge. Gently lift the camera bottom body-plate off.
2. Remove the two screws on the SD card slot side of the camera body and the two screws on the USB side of the camera body. Remove the two screws on each side of the viewfinder (one screw on each side). Gently pull the camera back-cover away from the camera body; it will still be connected to the camera by a ribbon cable.
3. Flip up the plastic retention bar on the center ribbon cable connector--there are three connectors--located on the exposed electronics board. Gently disconnect the ribbon cable from the connector. Place the camera back in a safe place.
4. Disconnect the remaining seven ribbon cables located on the exposed electronics board. De-solder the pink wire located in the upper left corner of the electronics board. Disconnect the white ribbon cable located along the top right side of the electronics board, under the four exposed ribbon connectors.
5. Remove the five screws that are holding the electronics board in place. Gently lift the board away from the camera, exposing the sensor board. The board will still be connected to the camera body by four wires along the bottom of the board. Gently lay the electronics board out of the way, taking care not to damage the four wires that are still connected.
6. Remove the three screws holding the sensor board in place and lift the sensor board out. Remove the two screws holding the spring loaded tension frame on the sensor board, then left the mount and carefully remove the exposed black gasket.
7. Remove the aqua-colored, anti-aliasing filter from the sensor with tweezers. Take extreme care to not touch the exposed sensor. Insert a clear plastic sensor cover in place of the anti-aliasing filter, replace the black gasket over the sensor cover and reassemble the camera.
8. Attach a Hoya R72 filter to the camera lens. Operate the camera as normal and take several test photographs so that you can adjust the "white balance" to suit your desires.
Building your own security camera gives you complete control over your installation.
Advancements in camera and computer technology have made creating your own security cameras simpler and more affordable for use at home or work. You can build a reliable security camera system using a moderately powered computer and store bought wireless camera, which allows you greater flexibility, control and placement of your system. Ensure your security and safety with the use of this security camera system guide.
Instructions
1. Determine the location and space that you want the camera to monitor. Depending on the area you want to capture, you may want to choose a camera with a wider lens. If you want to place the camera far away from the monitored spot, select a security camera with a telescopic lens. Mount the camera to your desired height.
2. Plug the USB wire from the camera into the USB transmitter. Depending on your transmitter, you may need to use an external power source, such as an electrical outlet.
3. Insert the USB receiver into your computer. Turn the computer on. After the computer has fully booted, turn the security camera on.
4. Open your "My Computer" window and locate the USB camera wireless device. If there is no icon, shorten the distance between the USB receiver and transmitter. Confirm that the camera and USB wireless components have power.
5. Load your video recording software. Test the camera buy pressing "record" and stepping into the surveillance area covered by the device. Review your recording, and adjust the camera's focus and frame rate if needed.

A wide assortment of paper is available to be used for printing, and there are many different properties to consider. Understanding the various properties of paper will help you select the best one for your print project.
Considerations
When selecting papers for printing, first determine what your project is and how the end product will be used. Paper choice for wedding invitations will be far different than that for outdoor advertising signs. You may select a delicate vellum for an invitation, but that is a poor choice for a poster that needs to stand up to some wear and tear.
Printing
Determine how the piece will be printed. If you are planning to use a commercial printer, you will have a much greater choice of sizes and types of paper. Conversely, if you are planning to use your own desktop printer, you will be restricted to the size and paper weight limitations of that device. Many desktop printers cannot print on card stock and cannot handle sizes larger than 8.5 by 11 inches.
Weights
Paper is defined by its weight, but those designations can be confusing. Basis weight is the term for describing paper. It is defined as the weight of 500 sheets (one ream) in the paper's parent size. There are a number of different parent sizes, depending on the type of paper, and that is where the confusion occurs. For example, cover stock parent sheets measure 20-by-26 inches. A typical cover stock for postcards or business cards is usually "65 lb.," meaning 500 sheets of it weighs 65 lbs. Index stock is a similar paper; however, its parent sheets are 25.5-by-30.5 inches. The typical basis weight for index is 110 lbs. By its designation, it seems like it would be much thicker, but those two papers are nearly the same thickness.
Sizes
Commercial printers are rarely restricted by size as many presses can print 40-inch wide sheets or even larger. Occasionally, printers have restrictions with sheets that are too small. For example, not all printers run presses that can print onto a postcard. If you are planning to use pre-cut post cards for a project, be certain your printer can run them. Also, when creating invitations, determine the envelope size first before assigning the size of your invitation. Envelopes sizes are limited, so you must match the invitation to the envelope, not the other way around.
Opacity and Coating
If you want to print on both sides of the sheet, choose a paper with higher opacity levels. Some papers are created to be opaque without being thicker, so they are a good choice for text books. Also, you must decide on the coating. Some stocks are available in both matte and gloss finishes, while others are uncoated. While raffle tickets will look fine on uncoated paper, photographic images will look flat if printed on anything other than coated paper.
Color
Be careful when choosing very bright colors of paper for your project. Fluorescent colors will draw attention, but if there is a lot of text, legibility is difficult. Again, determine what is most important about your project. If you have little type and want to draw attention, bright colors work well. If you are printing a book with a lot of copy, stick with white or a neutral color.
Finishes
Different papers have different surface finishes. Smooth, hard finishes work best for photograph reproduction and full-color images since the ink sits on the surface of the sheet and is not absorbed. Some papers have a linen, rippled or parchment effect on the surface. They add a nice effect to invitations and announcements.

The Cannon i860 is a photo ink-jet printer that has five ink cartridges and a print head that can be removed for cleaning. Maintaining and repairing your Cannon i860's print head and cartridges will save you money because you don't have to send the printer out for repair and deal with the hassle of being without your printer. Removing the print head from your Cannon i860 takes about two minutes and once it is removed, you can then do needed repairs and cleaning.
Instructions
1. Open the front cover on the Cannon i860 printer. If the printer is on, the cartridge holder should move to the center of the printer. If the printer is off, you can slowly pull the cartridge holder to the center, or turn the printer on and let the device pull the holder to the center.
2. Remove all of the ink cartridges from the cartridge holder. Place the cartridges upright on a piece of paper towel. This is a good time to clean the ink cartridges with a piece of paper towel. Wipe any ink from the bottom of the cartridges and check the condition of the cartridges---if any are leaking ink, replace with new cartridges.
3. Lift the gray-colored arm located to the right of where the cyan cartridge was. Then pull the print head out gently. Don't pull the print head out forcibly or it may break.
4. Place the print head on a piece of paper towel and do the needed repair or cleaning.
5. Place the print head back in the cartridge holder after you are done cleaning/repairing. Push the gray-colored arm down and then re-install the ink cartridges.
6. Turn the printer "On" if it is off and run a "test page" to test the device.

Silhouettes make lovely gifts and they are fairly simple to make. Black-and-white silhouette cutouts with a white border have a very distinctive look that differs from photos. Any parent or grandparent would appreciate having framed silhouettes of the children.
Instructions
1. Attach a large piece of paper on an open wall. Move the lamp within a few feet of the wall, and position your model so that he is sitting midway between the lamp and the wall.
2. Trace the silhouette of your model onto the paper on the wall. Place the traced image on a copy machine, and copy it at a reduced size. You might need to reduce the size several times before you get it to the size you like.
3. Cut out the silhouette, and trace it onto black construction paper or thin cardboard that you cut from a cereal box. If you use the cardboard, paint the silhouette black using any acrylic craft paint.
4. Cut out the black silhouette and glue it onto the white construction paper. The image is now ready for framing.
The Fuji A800 is a compact and lightweight eight megapixel camera with a 3x optical zoom. It runs on two AA batteries, and has 19 different picture modes, including an image stabilization mode, to assure that you get a good shot. The limited ISO range means that you need to be creative when shooting in low light, but the camera does have limited exposure compensation modes. The A800 was introduced in March 2007.
Instructions
1. Turn on the camera and press menu, then use the up/down arrows to scroll the quality and select "F," for fine, which is the highest picture quality setting.
2. Turn the mode dial on the upper right side of the camera to "SP" or scene position and press menu to access the scene modes.
3. Choose one of the 19 scene modes to tell the camera what type of shot you are taking and have it adjust the settings for you. The A800 offers modes for baby mode, red eye reduction, picture stabilization, portrait, landscape, sport, night, natural light, beach, snow, fireworks, sunset, underwater, flower, party, museum, text, manual and macro.
4. Press menu and then use the left and right arrows to scroll to ISO. The A800 has ISOs of 100 to 800. Use lower values for bright daylight and higher values for shooting indoors.
5. Press the flash icon to choose a flash setting. Use red eye reduction when shooting portraits and forced flash when shooting under bright light so that the light is balanced.

Subwoofers are audio speaker systems that deliver deep, low-frequency bass. Subs are designed to produce a heavy, satisfying bottom in music, and rib-rattling bass for action sequences in movies. Most subwoofers sold for home theater use are equipped with their own power amplifiers so the big drivers in the sub don't pull power from the main receiver or amplifier. With a few steps, you can add a new dimension to your audio experience.
Instructions
1. Disconnect the home theater receiver from the electrical outlet and make sure the sub is not connected to the power.
2. Place the sub anywhere in the room where it won't get in the way. Subs deliver an omnidirectional sound, meaning that the sub does not have to be pointed directly at the listening area. Place the sub where it can be connected to a power outlet or surge protector.
3. Plug an RCA-type audio cable into the Audio In jack on the back of the subwoofer.
4. Plug the other end of the cable into the Subwoofer Out jack on the back of your home theater amplifier or receiver.
5. If connecting 2 subwoofers to the same system, plug an RCA cable into each sub, then plug the other ends of the cables into a Y-splitter with an RCA plug. A Y-splitter is available at most electronics stores.
6. Connect the RCA plug on the Y splitter to the Subwoofer Out jack on the back of your main amp or receiver.
7. Plug the subwoofer electrical cords into a power strip surge protector and plug the surge protector into a wall outlet.

Many types of hot water heaters have electrical circuits; however, an electric hot water heater gets its name because it uses electrical power to perform the work of heating the water. Several different systems in a standard electric hot water heater work together so that the heater can perform its primary function -- to safely and efficiently heat water. These four primary systems include waterflow, temperature control, heating and safety.
Waterflow
Fresh cold water enters an electric heater at the top of the unit through the heater's inlet and into a pipe called a drip tube. The drip tube directs the water to the bottom of the heater's tank so any heated water at the top of the tank does not cool and can pass through the heater's outlet to the plumbing system when needed. When a faucet opens, it relieves the water pressure and fresh water enters the inlet, travels through the drip tube and pushes the hot water up and out of the outlet. The water then travels through pipes to the open faucet.
Temerature Control System
The control system of a standard electric water heater has two thermostat and heating element pairs extending into the tank and a control unit that provides interconnection and power. One thermostat and one heating element is located near the top of the tank and the others near its bottom. The control unit sends power through the upper thermostat and heating element and then to the lower thermostat and heating element. The interaction between water temperature and the thermostats control the water heater.
Heating Process
When first turned on, the upper thermostat takes priority and powers the upper heating element, which heats the upper tank nearest the outlet first. When finished, power transfers to the lower thermostat to heat the lower tank. When hot water is used, fresh water enters the lower tank, triggering the lower thermostat, which will attempt to heat the water as it enters the tank. As the hot water is used, the cooler water rises, triggering the upper thermostat, which will assume priority to heat the water nearest the outlet. Once that task is complete, the lower thermostat will heat the lower tank.
Safety Features
Modern electric hot water heaters have two primary safety features. The first is an over-temperature sensor that will remove all power from the unit should a thermostat malfunction. The second safety device is a pressure valve attached to the tank of the heater. If the water in the tank becomes overheated, it will cause an increase in pressure. This increase will trigger the pressure valve, which will vent the pressure out of the tank, preventing it from rupturing or exploding.

The Apple iPod is wonderful because you can take your music collection with you wherever you go. One place you deffinitely want to be able to listen to your iPod is in the car. You can do this with the help of a car adapter, but you need to know the two best car adapters for use with iPods, which one is right for your, and use it.
Instructions
Tape Adapter
1. Use a tape adapter, if you have a tape player in your car. The easiest and least expensive way to listen to your iPod is through a tape adapter. These basically look just like a cassette tape with a wire attached that runs to your iPod.
2. Purchase a tape adapter. It's best to buy one that is specifically made for iPods since ones that are not can cause annoying your iPod to randomly pause. Tape adapters specifically for iPods are available fairly inexpensively at any electronics or music store.
3. Plug the end of the cord into the headphone jack of your iPod. Slide the tape end into your car's cassette player. Now press play on your tape player and play music on your iPod normally. The music will be played through your car speakers.
FM Transmitter
4. Use an FM transmitter. If you do not have a tape player in your car, you can listen to your iPod via an FM Transmitter. This is a device that plugs into your iPod's headphone jack and broadcasts the music over an FM radio station so that you can listen to your music on your car's speakers.
5. Purchase an FM Transmitter at an electronics or music store. The most important thing to look for when buying an FM transmitter is to get one that can play on ALL the FM stations. Some transmitters only play on a few of the least-used stations and if you happen to live in an area where these stations are broadcasting, you are out of luck.
6. Find a clear radio station to play your music over. Turn on your car radio to FM and listen to each frequency until you find one that has almost no noise. Set your FM transmitter to that station number (i.e. 94.5). Play your iPod normally and the sound will be played through your car's speakers.

Equalizers that connect to your stereo system, such as those made by Yamaha, are used to adjust sound between levels. Sound levels include treble, mid-range and bass, which are set using slide controls on a panel. Connecting an equalizer is similar to connecting other types of components with your stereo or home theater receiver. To do this, you need to connect the audio cables correctly to each of the components.
Instructions
1. Press the "Power" button on the receiver to turn it off. Set the equalizer on top or below the stereo or a home theater receiver.
2. Plug the power cord for the equalizer into an electrical outlet or power strip.
3. Plug one end of an RCA stereo cable to the "Line Out" jacks for the CD or DVD output on the back of a stereo or home theater receiver.
4. Plug the other end of the RCA stereo cable to the "Line In" on the back of the equalizer.
5. Plug a second RCA stereo cable into the "Line Out" jacks on the back of the equalizer. The other end of the cable needs to plug into the CD or DVD "Line In" on the stereo or home theater receiver.
6. Press the "Power" button on the equalizer and stereo or home theater receiver to turn them on. Press the "CD" or "DVD" button on the receiver. This will send the audio signal to the equalizer.

Karaoke is a form of entertainment originating in Japan. With karaoke, amateurs sing along to music tracks minus the vocals. The words to the songs usually appear on a screen to prompt the singers. Karaoke discs are also used by professional singers to practice their vocals or to audition for singing jobs. Karaoke discs are widely available online or at music retail outlets, but it is often hard to find the songs you want. For this reason, many karaoke fans produce customized karaoke discs. Find out how you can create a karaoke disc that features all the songs you want to sing.
Instructions
1. Make a custom song list. This will help you refine your search. Determine which of the songs you can find as existing Karaoke tracks. Local music stores often carry a selection of Karaoke CDs. You can purchase Karaoke CD tracks that contain the songs you want to use on your own disc. Ensure that you are getting Karaoke CD-G (CD + Graphics) discs. If the discs aren't in the CD-G format, you won't have embedded lyrics on playback.
2. Use karaoke software or a karaoke disc duplicator to rip karaoke songs from original discs and burn them onto the custom disc you want to make (see Resources below). These software products read and write all CD-G information from the karaoke disc and burn it onto your custom disc. Most of the software products will even allow you to alter the key of the songs to fit your singing range.
3. Use software such as AV Video Karaoke Maker to add lyrics and graphics to karaoke music tracks that don't already have them (see Resources below). Many of the karaoke tracks downloaded from some services are simply musical tracks without vocals and not true karaoke (lyrics included for playback on a video screen). This software makes it as easy as dragging and dropping to embed lyrics on the song track for playback.
4. Take advantage of CD-G recording devices if you can afford to. The MTU Karaoke Disc Duplicator is a stand-alone unit (no computer required) that will duplicate karaoke CD-G information quickly and professionally. The duplicator transfers all lyric data as well as the music. Using any of these tools will enable you to create karaoke discs to fit your performing needs.
Sony's digital Mavica cameras all save images onto some sort of disk, such as a floppy or CD. Because the camera captures the content onto an external format, it allows you to download the images from the camera without ever hooking up the camera directly to your computer. This is because the images may be downloaded from the floppy disk or CD directly through the computer's floppy or CD/DVD drive.
Instructions
1. Eject the floppy disk or CD from your Mavica digital camera. (The format your camera saves content onto will vary depending on the model of the Mavica.) An eject button on the side of the camera pushes the CD/floppy disk out.
2. Insert the CD/floppy into the computer. If using a floppy disk, push it into the floppy disk "A:" drive. If using a CD, insert it into the disc drive of the computer and close the CD tray.
3. Click "Start," "(My) Computer" and double-click either the CD or floppy "A:" drive icon. A window appears with all of the files currently stored on the inserted media.
4. Click-and-drag the files from the open window onto the computer. (You may copy the images onto any location of the computer.) Then close out the open window. Push "Eject" on either the floppy or CD drive, and the disc will eject from the computer.

When recording for a long period of time, usually over 5 minutes, it can become tedious to hold a camcorder. To solve this problem, most camcorder owners invest in a tripod, or a three-legged camcorder holder. Tripods steady the camcorder, ensuring a stable shot, and allowing you to leave the camcorder for a short period of time. Here is use a tripod with a camcorder:
Instructions
1. Buy a tripod at any electronics store, on the Internet, or at a local discount store. Be sure that the mount is compatible with your camera.
2. Find a good location for the tripod. Depending on the event, you will want to place the tripod where its view is not encumbered and it is away from high-traffic areas where it could be knocked over.
3. Assemble the tripod, per the manufacturer's directions and place your camera on top. Most camcorders will screw to the top of the tripod.
4. Secure the camcorder on the tripod and adjust the height. You will want it to be above head-level of people sitting or possibly walking in front of the camera.
5. Find the shot and press record. Utilizing the camcorder remote control at this time will make it easier to record.

To "Unlock" an iPhone is to hack it so it can be used with other cell phone carriers than AT&T. The most common carrier to switch to is T-Mobile as it is another GSM carrier. Companies like Verizon and Alltel will not work with the iPhone because they use a different radio signal known as CDMA. In order to unlock the phone, first it must be "Jailbroken". This article will assume the reader's phone isn't jailbroken.
On the computer
Navigate to the "Resource" section of this article and download the program "Blackra1n". This is a program made by a hacker named "George Hotz". Currently, the Blackra1n program is on version 3, and this is the version that will download from the website in the "Resources" section of this article. It is free and there is no charge to use it. After the program download, double click on the "Blackra1n" icon and it will display a button that says "Make it Ra1n". Click on this when your iPhone is connected, and it will jailbreak your phone. (It will usually take less than a minute including the reboot.) When the jailbreak is complete, your phone will display a picture of the hacker (George Hotz) and a few iPhone's dancing around his head. After that picture displays for a few moments, the iPhone will reboot in its jailbroken glory.
On the phone
Look for the icon for "Blackra1n" it will appear, just like an application on your iPhone, and it will look like a single black raindrop. Tap, and open this application to be greeted with four options. You can install "Cydia" (a free jailbroken app store), "Rock" (a smaller lighter version of Cydia, but it costs money), or "sn0w" (the unlock application for the iPhone). There is also an uninstall option to remove the "Blackra1n" icon, but you want to install "Sn0w". Tap on "Sn0w" and then "Install". When the "Snow" application downloads and installs, tap on it and it will automatically begin to unlock the phone. After it finishes, it will respring (reboot) the phone, and your phone will be unlocked.
Choosing T-Mobile
Make a note of other GSM signal cell providers that will support the iPhone. There are smaller, local cell phone companies that will do this, but the largest nationwide provider of GSM under AT&T is T-Mobile. Not only can the iPhone run on T-Mobile, their customer service "unofficially" supports the phone. Their customer service won't help with jailbreaking, or unlocking the phone, but once those things are done, they are dedicated to assisting you in any way possible. To run the iPhone on a T-Mobile network, you will need to purchase their unlimited internet package (as of December 2009 it is 24.99) and wait for the sim card to arrive. When it arrives, insert it into the iPhone and tap "Settings", "General", and "Network". Once on that screen, click on "Cellular Data Network" and enter "internet2.voicestream.com" into the box labeled "APN". This will get the internet working on the iPhone. Voice calls will work with just the sim card.

On-board flashes often cause harsh lighting in the center of photos.
The Nikon D700 is a powerful digital camera for serious photographers. It carries an on-board flash, but the flash isn't strong or flexible enough to help you capture the best possible photos in any lighting situation. Your flash should be able to even out shadows in bright daylight as well as add light to dark situations. The Nikon SB-400 flash offers the flexibility, mobility and power needed to even out your light in the harshest conditions.
Weight
Flashes can add an enormous amount of weight to your camera. The SB-400 flash is lightweight, which makes it ideal for photographers on long shoots or who are carrying their camera for long periods of time. The SB-400 weighs in at just heavier than 6 ounces with the batteries.
Tilt
The SB-400 offers a tilt feature to allow you to bounce the flash off the ceiling. Bouncing the flash diffuses the light and evens out the lighting in the room to reduce shadows. The tilt feature also allows you to change the direction of the light in your photos.
Recycle Time
Many flashes take several seconds to recycle, or recharge and prepare for the next flash. The SB-400 recycles in about three seconds, allowing you to take quick consecutive shots.
Price
The Nikon SB-400 is affordable, at $120 at the time of publication. Larger flashes, such as the Nikon SB-600, start at $350. Although it has a sideways swivel feature the SB-400 lacks, the SB-600 is much heavier and takes longer to recycle. The SB-400 uses only two AA batteries, which makes it affordable throughout its lifespan; most other flashes use four or six batteries.

Car amplifiers are built to provide dependable, powerful output in a tough environment. Why not take advantage of those capabilities at home? The problem is that car amplifiers are made to operate on 12-volt DC power, not the 110-volt AC power we use in the home. Yet, with the addition of an AC to DC power supply, you can put your car amplifier to work at home.
Instructions
1. Decide where you'll place the amplifier and power supply. Both components will generate heat when operating, so pick a spot that is ventilated and provides at least one inch of open air space around each component. You'll also want to have ready access to an AC power outlet for your power supply.
2. Cut a length of insulated power and ground cable long enough to reach from the power supply to the amplifier. Consult your amplifier's manual for the recommended gauge for the power wire, but as a rule of thumb don't go thinner than 10-gauge wire. Strip 3/8 to 1/2 inch of insulation from the ends of each piece of cable.
3. Cut a length of 16- or 18-gauge insulated wire the same length as the power cable. Strip 3/8 to 1/2 inch of insulation off both ends of the wire. Twist together one of the bare ends of this wire with one end of the power cable.
4. Using a crimping too, crimp ring terminals onto the end of the power cable with the added wire and onto one end of the ground cable. Ring terminals are round, ring shaped connectors that are crimped onto the ends of bare wires to provide a solid electrical connection when you're attaching power or other cables to post connectors.
5. Loosen and remove the thumbscrews or wingnuts on the power supply's power and ground terminal. Slip the ring terminals over the posts and replace and tighten the thumbscrews or wingnuts.
6. Loosen the screw terminals of the amplifier's power, ground, and remote terminals with a Phillips screwdriver or hex wrench. Slide the appropriate wires into the openings and tighten down the screw terminals you loosened previously.
7. Plug in the power supply and switch it ON---this will turn on the amplifier.

The Nikon D40 is a light, inexpensive digital single lens reflex (SLR) camera. It has a 6 megapixel sensor and was introduced in 2007 to replace the Nikon D50. This camera is an excellent entry level digital SLR that works well in bright or low light conditions. Using a Nikon D40 is similar to using a traditional film SLR; it requires an external lens and has manual modes which give great artistic control over your results.
Getting Started
Nikon's D40 requires a Nikon bayonet style F-mount lens. This camera can use both old and new lenses. Due to the sensor's size, this camera achieves best results with Nikon's DX range of lenses, which are optimized for the digital sensor. Attach the lens to the camera by removing the cover on the front of the camera. Align the white dot on the lens with the white dot on the camera body, insert and twist until the lens is locked into place. To release lenses, push the lens release button located on the front of the camera body and gently twist the lens. Always use covers on the exposed lens and camera body when changing or storing equipment to prevent dust from settling on the lens and mirror.
On the right side of the camera you will see the door for the memory card slot. The Nikon D40 takes SD card memory; there is no internal memory on this camera so you must insert a card to continue.
At the bottom of the camera is the battery compartment. The Nikon D40 is sold with a lithium-ion EN-EL9 battery, which is rechargeable. Insert the battery into the compartment, and you are now ready to use your Nikon D40.
Taking Your Photos
On the top, right-hand side of the camera body is the on/off switch. Set this to "ON" to start shooting. Make sure all lens covers are removed.
Select your shooting mode from the dial located on the top right side of the camera body. The modes on the Nikon D40 range from fully automatic to fully manual, with many modes in between for specific purposes, such as fast action or close range shots.
If you have selected a manual or partially manual mode, adjust any manual settings. For aperture priority mode, this allows you to adjust the aperture. Hold down the "+/-" button on the top of the camera while turning the wheel located at the upper right of the camera body. The changing aperture settings will be displayed on the LCD. In shutter priority mode, simply turn the wheel to adjust the shutter speed. This also applies to program mode, where you may switch between appropriate shutter speed and aperture combinations using the wheel. The fully manual mode allows you to select both shutter speed and aperture, giving total artistic control over the shot.
If necessary, press the small lightning bolt button at the top of the camera to release the flash. You can also use the hot shoe flash attachment to attach an external flash unit to the camera.
Point the camera at your subject and depress the shutter button slightly. This will activate the auto focus feature. This feature may not work with older lenses. Correct your focus, then depress the shutter button fully to capture your image.
From Camera to Computer
Once your photos have been taken, they may be transferred to your computer using a card reader or the camera. If you are using a card reader, remove the card from the camera by opening the door on the right side of the camera and pressing gently on the card until it pops out.
If you are using the camera to remove your images, you will need to use a USB cable. Turn your camera off and remove the rubber cover on the left side of the camera body. Connect the USB cable to the port on the camera and plug the other end into your computer. Turn the camera on; this will begin the photo import process. No additional software should be required. The photos can then be saved, manipulated or deleted.

Accessing images on a memory card helps share your photos with friends.
Retrieving photos from a memory or media card can be accomplished by using a card reader and a simple drag-and-drop transfer method. Using a card reader is recommended for speed and ease of image transfer. Be sure your computer has the necessary storage space for your images and try to keep them organized for easy retrieval at a later date.
Instructions
1. Attach a card reader to your computer using the USB connecting cord provided with your card reader. A card reader is an inexpensive and efficient means of transferring images from a memory card to the computer, and is a faster method than transferring from the camera or a built-in PC card slot. Be sure you purchase a card reader that fits your memory card type or buy a reader with multiple slots for various media cards.
2. Insert the media card into the reader and allow the computer to recognize the media device. At this point, the card actually functions as an external hard drive and will show up on your computer in the same location as a jump drive or attached external drive.
3. Double-click the icon for your card reader or memory card. The drive is sometimes labeled by the digital camera which captured the images onto the card and can usually be found in your Computer window on a PC or your Desktop or Finder window on a Mac.
4. Select the folder on your memory card which holds the photos you wish to retrieve.
5. Hold the mouse button down once the folder is selected and drag the folder icon onto your desktop.
6. Allow the computer to transfer the images before disconnecting the card reader or removing the card. The transfer time will vary depending on your computer speed, hard drive space and the amount of images you are transferring.

Both binoculars and spotting scopes enhance outdoor activities.
Outdoor enthusiasts in many pursuits utilize both binoculars and spotting scopes in their endeavors. Binoculars offer simple portability, while spotting scopes increase visual range in bird watching, target shooting, telephotography and amateur astronomy.
Common Concerns
Comfort is a major factor in an optics purchase.
Purchasers of either binoculars or spotting scopes should consider lens clarity and comfort of handling; rugged outdoor enthusiasts should also consider lens composition. Nitrogen-filled optics resist fogging.
Advantages of Binoculars
Lens composition and size affect binocular usability.
Hung around the neck or supported by shoulder straps, binoculars offer swift reaction times for chance encounters with wildlife. When binoculars are flipped, the lenses become instant magnifying glasses for microscopic investigations.
Advantages of Spotting Scopes
Spotting scopes are smaller, more portable versions of telescopes.
When supported by a tripod, a spotting scope offers a stability that is impossible with binoculars. Coupled with intensified magnification power, that stability allows for increased opportunities to scrutinize distant objects.
Cameras
Digiscoping adds a new layer to outdoor pursuits.
Many spotting scope manufacturers offer adaptation packages that permit the attachment of digital cameras to eyepieces, facilitating the transition from simple observation to distant digital photography, known as digiscoping.
Price
Optics are serious investments.
Binoculars range in price from $100 to $600. Spotting scopes, without tripods, run as high as $3,000.
Everyone is on the go these days, with Ipods, Cell phones, PSPs, and so many more handheld devices, but if you still want to play your big video game system on the run, you can easily hook it up to a portable DVD player. Not every portable DVD player may be compatible, but more of them are and will allow you to play your favorite video game systems anywhere.
Instructions
1. Make sure that your DVD player is compatible. The first things you need to look for are input/output ports. Most of the portable DVD players will have headphone jacks and power outlets, but you need to find audio/video ports, usually, black, red, or yellow.
2. Make sure that the DVD player accepts incoming connections. There will be a small switch on the side of the player that indicts whether you are using the ports as an input or output.
3. Purchase two RCA to Mini-plug adapters. These are essential in hooking up the system, and without them it will be nearly impossible to connect it. You can find these at a local electronics store like Radioshak.
4. Attach the adapters to the ends of your video game system RCA cables. There will usually only be one audio input, so use the white audio cable and just leave the red hanging.
5. Plug the audio jack into the proper slot on the portable DVD player. Plug the video jack into the proper slot on the portable DVD player. Set the switch to “Input” on the portable DVD player.
6. Look for the gaming system start up on the DVD player screen. If you do not see the video game system load, the cords are either loose, in the wrong spot, or the adapters were not put on correctly.
7. Purchase a power converter for your car and plug the video game system right into the power source that is connected to your car to make the gaming system truly portable.

Professional photographers use various types of lighting equipment. Photography strobes flash a burst of lighting onto the subject. They provide bright, even lighting and are great for portrait and wedding photography. You don't need to be a professional photographer to use strobe lights and you don't have to spend a lot of money on purchasing them. You can put together your own do-it-yourself photography strobe.
Instructions
1. Pick out an external flash. The price range varies with the speed, brand and brightness of the flash. If you are just starting out, you may want to go with an inexpensive model while you learn the ropes.
2. Set up a tripod and attach the external flash to it. Depending on the type of flash you bought, it may have an adapter or you may need to purchase one from a camera supply store.
3. Prepare your reflective umbrella. These can be purchased rather inexpensively from a camera supply store or you can make your own. Take a lightweight umbrella and spray-paint the underside white or silver. The color of the inside will effect the light that it reflects. Silver will bounce most of the reflected light while you will lose up to 50% of the bounced light with white.
4. Attach the umbrella to your tripod/flash configuration. If you purchased a lighting umbrella, you may be able to attach it directly to the tripod. You may need to use duct tape or a heavy duty tape to attach it. If that's the case, attach the umbrella upright, but at a slight angle so that the flash will reflect off of it and onto your subject.
5. Aim the flash at the umbrella. Make sure your flash has batteries and plug it into your camera. When you take a photo, your new strobe should go off. If it doesn't, ensure that it is properly set up with your camera. Adjust the angle as needed.

SLR cameras are suitable for portrait photography.
Take a picture of a child and they want to immediately see their image. Adults are also fascinated with having their image captured. As a portrait photographer, you have the task of not only accomplishing that, but creating images that your friends, family and customers are happy with. Your camera helps you accomplish this task.
Identification
The most common type of camera used by portrait photographers is the SLR, or single lens reflect camera. An SLR works by quickly moving a mirror away from the camera sensor to create an image. Both film and digital SLR cameras have removable and interchangeable lenses, making these professional-quality cameras easy to identify.
Benefits
SLR cameras offer the most control over the settings and features on your camera, making them ideal for portrait photography. Photo settings like aperture and shutter speed help create various effects in portraiture, such as softened features and a blurred background. SLR cameras also take many shots in quick sequence, allowing minute variations in expression for capture.
Expert Insight
The most effective lenses for a studio portrait camera are between the 33 and 66 mm range. Cameras that are not fully-functioning SLR cameras may take quality studio portraits, but they will not offer the range of advantages that a professional grade SLR camera will. In addition, even the most expensive studio portrait camera will not make up for poor lighting in the shooting environment.

The Nikon version of the Tokina AT-X 124 AF Pro DX 12--24mm f/4 lens can be used on other Nikon cameras thanks to the universal F-mount system. The Nikon F4 and all other variants of the F4 camera are capable of mounting and effectively using the Tokina 12--24mm lens.
Instructions
1. Mount the Tokina lens the same as a Nikon-brand lens by aligning the index mark on the lens barrel with the index mark on the camera body and twisting the lens counter-clockwise until the lens locks in place.
2. Set the F4 camera to program mode using the shutter speed dial (P on the dial). Because the Tokina 12--24mm lens does not have an aperture ring, program mode must be used in order for the aperture to adjust to the lighting conditions to take a correct exposure. Otherwise, in manual mode, the aperture will remain at maximum f/4 for all photographs.
3. Alternatively, set the F4 camera to shutter-priority mode using the shutter-speed dial (S on the dial). This allows the user to choose a shutter speed while the camera selects an appropriate aperture based on the meter reading in the camera. This allows for greater flexibility and control by the photographer than using the program method.
4. Set the F4 camera to autofocus (S or C) using the selector switch on the left-hand side near the bottom of the front of the camera. To focus the Tokina manually, switch the selector to manual (M) and use the electronic rangefinder in the viewfinder window of the camera to confirm proper focus.

Although technology has progressed greatly in the 12-volt appliance market, many mobile individuals still find themselves with the need to utilize 110-volt AC-powered equipment such as blenders, mixers, televisions, and other devices that may only be plugged into a wall outlet found in a building. The car's electrical outlets are generally cigarette lighter-styled receptacles, and the DC power of these outlets must be converted into alternating current (AC) to run the desired appliances. Modern technology has progressed in making this car-outlet conversion possible.
Instructions
1. Determine a location along the bottom of your dash where you desire to mount your power inverter, making sure the mount location isn't too far away to prevent plugging the device into the nearest cigarette lighter outlet.
2. Screw in the self-tapping screws that came with your power inverter. Drive the screws through the mount's screw holes and into the lower dash trim.
3. Insert the inverter's cigarette lighter adapter plug into the 12-volt cigarette lighter receptacle and turn the inverter switch to the on position. Observe the power indicator light to ensure the unit is receiving power. Depending on your vehicle, you may have to turn the ignition switch on to power the lighter receptacle.
4. Plug in your appliance into one of the three-pronged outlets on the inverter and use the appliance as you normally would at home.

Car amplifiers provide a lot of amplification power in a small package. But because they're designed to operate on a 12-volt DC power supply, they're not usually used in homes. But with an AC to DC power supply, you can add your car amplifier to your in-home audio arsenal.
Instructions
1. Place your amplifier and power supply in a well ventilated location, near a power outlet. The amplifier and power supply will generate heat when operating, so be sure that there is enough room around the components to let air circulate.
2. Measure the length of power and ground cable you'll need. Your power and ground cables will need to reach easily from the terminals of the power supply to the terminals of the amplifier. Take into account how you'll need to route the cables when measuring.
3. Cut your power cable, ground cable and remote turn-on wire to the correct length. You'll use the measurements taken in Step 2 for this step. The remote turn-on wire is the 16-gauge insulated wire--cut it to the same length as the power cable.
4. Remove 1/2 inch of insulation from both ends of each cable with your wire strippers.
5. Twist together one end of the power and remote turn-on wire. Slip a ring terminal over the end and then crimp the terminal onto the wire with your crimp tool.
6. Crimp a ring terminal on one end of the ground cable.
7. Loosen and remove the wing nuts on your power supply's terminals. Slide the ring terminal of the power cable onto the "+" post, and the ring terminal of the ground cable onto the "-" post. Replace the wing nuts and tighten them until the power and ground cables are securely fastened.
8. Loosen the Phillips screws or hex screws of the amplifier's "+," "-," and "REM" terminals. Slide the bare end of the power cable into the "+" terminal, the bare end of the ground cable into the "-" terminal, and the turn-on lead into the "REM" terminal.

Proper cell phone battery conditioning will ensure long life for your phone and battery.
Conditioning a cell phone battery properly is a process that every purchaser of a new cell phone should follow. Too often, though, new cell phone owners do not follow a proper battery conditioning regimen, resulting in a bricked battery that cannot hold a charge. If you properly condition the battery, it should provide years of use.
Instructions
1. Assemble your cell phone as directed. In nearly all cases, your cell phone battery will be partially charged to begin with. Do not plug in your cell phone right away, instead use it normally until the battery is completely discharged. (If you improperly charge your cell phone the first couple of times out, you can easily ruin the battery.)
2. Plug your cell phone, battery intact, into a wall charger. Do not charge your cell phone via USB or a car charger the first time out, as the voltage will not be the same. To condition a cell phone battery properly, use the original equipment charger with the proper voltage.
3. Use your cell phone as normal, now that it is fully charged. To condition a brand new cell phone, try not to use media or web-heavy functions straight off the bat that will drain the battery quickly. You want the battery to discharge the first few times at a slow, even rate.
4. Drain the battery fully before plugging the cell phone in. Do not fall into temptation to plug the cell phone in a second time before the battery is fully drained. While this will not damage your cell phone or battery during standard use, you need to properly condition the cell phone battery by draining it completely before plugging in.
5. Repeat the process four or five more times before even thinking about plugging in your cell phone when you still have battery power left. After completing proper cell phone battery conditioning, it will not hurt your cell phone battery to plug the cell phone in every night or to convenient power sources such as USB ports during the day. Conditioned cell phone batteries are meant to be able to catch a few minutes of charge as needed, but it is the first few days that are vital to good conditioning.
6. Continue to drain your cell phone battery completely before plugging it in at every available opportunity. Regardless of the age or conditioning of your cell phone battery, it will always last longer over time when discharged fully before charging again. Don't obsess over it to the point where it affects the way you use your phone; $35 for a new cell phone battery is not the end of the world.

Take your DJ performance digital with a touch screen.
The days of scratching a vinyl record while DJing are long gone. Although that sound can still be emulated, it is all done digitally now. One such development has introduced the world to touch-screen DJing, where you as the DJ use a touch-screen surface to provide music for the whole night. This minimizes the amount of equipment you need to bring while maximizing the different tools you can utilize to help keep the crowd dancing.
Preload Performance
The touch-screen DJ software interfaces allow you, the DJ, to preload the songs you want to play for the evening. Preprogramming the event lessens the chance for mistakes during the course of the night. You can also override previous choices by using your finger to drag and drop new or different music choices depending on the vibe of the crowd. Simply time out the approximate length of the event. Be sure that you include music for any special moments, such as a bride's first dance or a happy birthday tune at a birthday event. You can even send the song list to the client for approval ahead of time. Then simply press "Play" on the touch-screen software and kick off the event.
Audience Interaction
Part of the experience of being a DJ is the interaction with the audience. Purchase touch-screen DJ equipment that has a clear underside so that the audience can see what you are doing during the performance. The clear underside will allow people to see how you are adjusting the controls, spinning the records and making each song your own. If you do not have a clear underside, you can hook your computer equipment up to the monitoring system, which can be projected on the club's TV or projection screens. The hook-up is different for each interface, but look for audio visual cables that connect to USB ports or other outputs on your equipment.
Customize the Workstation
DJs have different styles and tools that they need during an event. For instance, a wedding DJ may use the cross fade function a lot as the music overlaps with speeches from the wedding party. A club DJ may need a scratch function to change up the music midstream. Build your touch-screen DJ console so that it is personal to you. Place items on the left or right side of the screen depending on your preferences for how you like to work. Also, some software allows you to save different touch-screen interfaces. So you can create one for weddings and another for clubs.
With the XM Direct 2, you can seamlessly add XM satellite radio to your car's aftermarket head unit.
The XM Direct 2 is a satellite radio adapter for aftermarket vehicle head units that are XM-Ready or SAT-Ready. It will allow you to tune into XM Radio through your head unit and surf channels, navigate categories and control other satellite radio features as you would those of any other integrated audio component. Because the installation takes place behind the in-dash head unit, it is a fairly involved process and professional installation is recommended for those who are not familiar with car audio installation.
Instructions
1. Check the compatibility of your aftermarket head unit. You can do this by checking the model number of your head unit against the compatibility chart on the Audiovox website.
2. Purchase the correct model-specific head unit cable interface for your brand of aftermarket head unit. Compatible brands include Alpine, Clarion, Eclipse, Jensen, JVC, Kenwood, Panasonic and Sony. You can purchase these from an authorized dealership or direct from the Audiovox website.
3. Download the proper radio model protocol to your protocol interface adapter. You can have an authorized dealer do this for you. Alternatively, do it yourself by downloading the correct application from the Audiovox website. You will need a PC with Windows XP and a USB to mini-USB cable. Full instructions for downloading the application can be found at the Audiovox website.
4. Decide where you plan to install your XM Direct 2. It should be within 3 feet of your aftermarket head unit to ensure the cables reach adequately, and located behind the dashboard for a seamless appearance.
5. Install your XM antenna. It attaches to your vehicle roof magnetically. You should place it in a location where the antenna cable can easily and discreetly enter the passenger compartment. We recommend the rear of the roof, where it can enter through the truck. Tuck the antenna cable into the rubber window seals and under carpets and interior trim to hide the cable from view. It should come out behind the dash, with enough slack to easily connect to the XM Direct 2.
6. Remove your aftermarket head unit from your dashboard. Depending on how you installed it, you may need to unscrew dashboard components and remove trim to do this. You need to remove it from the dashboard enough to be able to easily access the input jacks on the rear of your aftermarket head unit.
7. Connect the protocol interface adapter and your aftermarket head unit with the model-specific head unit cable interface cable.
8. Connect the XM Direct 2 Tuner to your protocol interface adapter with the included cable. Connect the XM antenna cable to the back of the XM Direct 2 Tuner.
9. Start your car and turn on your aftermarket head unit to confirm that you have installed the XM Direct 2 Tuner correctly. You should be able to access Satellite Radio or XM radio mode on your head unit, and tune to XM channel 1. If you hear audio and see XM preview information displayed on your head unit display, you have correctly connected the XM Direct 2 components.
10. Secure the protocol interface adapter and XM Direct 2 Tuner behind the dashboard with Velcro, double-sided tape or cable tidies to hold them securely. You should make sure they don't vibrate, rattle or interfere with any other equipment installed in your dashboard.
11. Reinstall your aftermarket head unit in your dashboard and tighten any screws or replace any trim required. Tidy any loose cables by stowing them behind the dashboard, trim panels or under the carpet.
12. Activate your XM radio service by turning on your car and tuning to XM channel 1. You can follow the instructions onscreen or activate your XM account online at the SiriusXM website.
