Troubleshoot A Jvc Grd370u

JVC's GR-D370U digital video camera is a Mini DV (Digital Video) cassette, SD (Secure Digital) and MultiMediaCard compatible device. It is not compatible with other memory formats. The camera records in NTSC format. Problems with the digital video camera can be related to power, recording, playback, advanced features like focus and other issues. Problems that occur with the JVC GR-D370U can be rectified by following some troubleshooting steps.


Instructions


1. Connect the power properly if the camera will not charge. The battery pack should be secure and not move. The AC adapter should be firmly connected. Remove the battery and the AC adapter and reconnect to confirm.


2. Set the tape's erase protection tab to "Rec" if recording cannot take place. The tape may be locked on the "Save" setting. The tab is on the back of the cassette.


3. Clean the tape heads if recording quality has deteriorated over time and playback is poor. Tape heads are prone to wear and eventually deteriorate. Insert a commercially available tape head cleaning cassette. The mechanical nature of the tape functionality also will cause problems with age. You may find longevity in the product by using the card recording functionality whenever possible because the card function is not subject to the same wear.


4. Set the focus to the "Automatic" mode if the focus does not adjust automatically. Press the "Focus" button twice to get there. Other advanced features allow you to make fine adjustments to backlighting conditions. Press the "Backlight" button to compensate for backlight. Set the recording mode to "M" and then choose an effect like "Spotlight" for example, if you want to compensate for subjects that appear too bright, like when shooting in strong lights.

Burn A Mini Dvd

A Mini DVD holds just a fraction of storage compared to a full-size DVD.


A Mini DVD is similar to a typical full size DVD but its diameter is only 8 cm across. Because of the lesser physical size of the disc, it also holds less data -- 1.4 gigabytes instead of the standard 4.7 gigabytes. Burn information to a Mini DVD by following the same steps as burning a regular DVD, provided that the disc is large enough to fit all the information.


Instructions


1. Insert the Mini DVD disc into your DVD writer disc drive. Center the disc in the tray so it will spin properly and be read by the laser.


2. Launch your disc writing software that you typically use to write information to DVDs or CDs. Select the "DVD" medium instead of "CD-R" or other media options presented. Also choose the format of disc you'd like to create, such as "Data Disc" or "Video Disc."


3. Place files onto your disc. Navigate within the box containing items in your hard drive and select items to add to the list. Keep an eye on the total amount of information you've queued to burn and make sure it is below 1.4 gigabytes.


4. Click on the "Burn to disc" button. A progress bar will appear. The task will take several minutes to complete.

Fix The Laser Eye On The Aiwa Threecd Changer

An Aiwa Three-CD Changer is similar to all CD players in that a laser is used to read the compact disc placed in it. Vibrations from the player's motor can cause the laser "eye" to no longer be at the optimal position for reaching data off the CD. You can fix the laser so that it once again is looking directly at the CD from the proper position. A few household tools are needed since you will have to partially disassemble the Aiwa.


Instructions


1. Press the "Eject" button on the front of the Aiwa CD player to eject the disc tray. Remove the discs from inside the tray. Close the tray, turn off the Aiwa and unplug its power cord from the wall outlet.


2. Turn the Aiwa around so that the back is facing you. Remove the screws from the top left and right corners on the back panel with a Philips screwdriver. Remove the screws from the lower left and right corners on the back panel with the screwdriver. Remove the screws along the bottom edge.


3. Grip the sides of the Aiwa and pull the outer cover towards you. Stop pulling once a gap is seen between the far end of the outer cover and the front panel. Insert the tip of a flat-edged jeweler's screwdriver into the gap at one side. Pull the tip back toward you to further increase the gap. Repeat this on the right side of the Aiwa. Grip the sides of the outer cover and pull it off. Place it aside.


4. Locate the spindle at the center of the motor on the inside of the Aiwa -- the disc tray is connected to one end of the motor. Push the disc tray away from the motor to extend it fully outwards.


5. Shine a flashlight at the spindle to reflect the beam off the laser lens. Make a note of where the laser lens is located. Locate the screw that is next to the lens -- the potentiometer, or "pot," can be used to change the position of the laser "eye."


6. Insert the tip of the flat-edged jeweler's screwdriver into the "pot" screw. Rotate the screw a quarter turn clockwise.


7. Plug the Aiwa's power cord back into the wall outlet. Place a CD on the disc tray and close the tray (use the Aiwa's remote control to do this). Press the "Play" button and listen to how the CD sounds -- if it doesn't sound OK, stop the disc, unplug the power cord and adjust the "pot" screw a quarter turn again. If the CD sounds okay, stop the CD playing and remove the disc after ejecting the disc tray. Unplug the power cord and place the outer cover back on the Aiwa. Reattach the screws.

Set The Depth Of Field On A Wide Angle Zoom Lens

A wide-angle zoom lens.


Wide-angle zoom lenses offer great performance for a variety of different photography styles, and proper control over depth of field will unlock their true potential.


Instructions


Digital SLR Cameras and Modern 35mm Cameras


1. A 35mm SLR camera body, minus a lens.


Attach the wide-angle zoom lens to your camera, ensuring it is firmly in place.


2. A digital SLR mounted on a tripod for rigidity.


Frame your shot. A tripod will help if you are aiming to capture a very large depth of field with a slower shutter speed.


3. A camera dial, used to change shooting mode.


Use your camera's aperture priority mode (A) or manual mode (M). Aperture priority will leave the camera to determine the shutter speed, manual mode will require the photographer to specify shutter speed.


4. A photo with a very shallow depth of field.


Use your camera's controls to choose your aperture. Higher aperture values--a lower f-stop number--provide a shallow depth of field with clear areas of sharp and blurry contrast. Lower aperture values--a higher f-stop number--capture a wider depth of field, with a larger area of focus.


Traditional Manual 35mm SLR Cameras and older lenses


5. A traditional manual 35mm SLR camera.


Attach the wide-angle zoom lens to your camera, ensuring it is firmly in place.


6. A photographer using a tripod to hold a camera in position.


Frame your shot. A tripod will help if you are aiming to capture a very large depth of field with a slower shutter speed.


7. A 50mm prime lens with aperture ring.


Twist the thin aperture ring on the lens to choose an aperture appropriate for the shot. Higher aperture values--a lower f-stop number--provide a shallow depth of field with clear areas of sharp and blurry contrast. Lower aperture values--a higher f-stop number--capture a wider depth of field, with a larger area of focus.


8. A photographer, calibrating his next shot.


Set the shutter speed, paying close attention to your camera's light meter to ensure perfect exposure.

Fix Redeye In Pictures

Even the most beautifully posed photo can be ruined if the camera flash causes a red-eye effect. Red eyes in photos can render an otherwise perfect photo useless for display. Fortunately, thanks to the modern wonder of digital photography, it is fairly easy to fix photos that have been tainted with red-eye.


Instructions


1. Acquire digital photos. You can do this either by downloading them directly from your digital camera or by scanning preprinted photos to your computer.


2. Open the photos in your editing software, and save the photo as a new file name to avoid overwriting the original.


3. Zoom in on the eye you wish to fix so that you can see what you are working on better. Click on the desaturation tool, and set the strength to 100%.


4. Hold down the mouse button, and move the desaturation tool over the red area of the eye. You may have to sweep over the red part a couple of times to make sure all the red is removed.


5. Click on the burn tool, and set the strength to 50%. Run the burn tool over the pupil of the eye to darken any areas that looked washed out due to the red-eye glare.

Test & Adjust Tube Amplifiers

Guitar players love tube amplifiers for the warmth of their tone. All tube amps have different qualities. The trick is to find the right amp for you and to keep it in well functioning order. There are several things to consider in regards to testing and adjusting tube amplifiers. Test the amp before you buy it. There are a wide range of options for tube amps. Besides the minimal requirement that everything works, remember that you are search of the right sound. Tube amps need to be regularly maintained. Some of this you can do yourself and other adjustments need to be made by someone qualified to work with high voltages.


Instructions


Finding The Right Amp


1. Test the amplifier with your own guitar. Guitar amplifiers respond differently to different guitars as well as different guitar styles. Use your own guitar to test the amp playing at different volumes while using various guitar techniques.


2. Experiment with the tone controls. Tweak the tone controls to find the sound that you are seeking. The treble, bass and middle tone controls respond differently on different amps. Try different settings to find the sound that you like.


3. Test the amplifier in a live band setting. Most guitar stores have a 10-day return policy assuming there are no scratches, scuffs or other damage. A good tube amplifier will cost $1,000 to $2,000. It is important to know how it performs in a live situation with bass, drums and other instruments. It may sound great at home but you may find that it it doesn't perform well at the gig.


Take Care Of The Amp


4. Learn the symptoms of bad tubes. Tubes are unpredictable and may last for a long time or only for a short time. The general rule of thumb is that you should replace the power tubes every one to two years if you are playing on a regular basis. The preamp tubes can be changed less frequently. You can stay on top of the situation by knowing the symptoms of bad or weak tubes. A loss of tone control and power indicates a problem with the power tubes. The sign of a bad preamp tube is a high-pitched squealing sound. Always keep extra tubes with you in case you need to replace them at a gig.


5. Take your amp to the guitar store for an annual tuneup. Guitar amplifiers are high voltage, and, therefore, highly dangerous. The tubes need to be biased properly, and this is a job for a professional. If the tubes are not biased or balanced, the sound quality of the tubes will be bad and the tubes will burn themselves out. While the tubes are being biased have the tube sockets re-tensioned and tightened as well.


6. Include an inspection of the capacitors and resistors in the annual tuneup. This is another job for a professional. Capacitors are filters that look like metal tubes in the back of the amplifier. Worn out capacitors will have a detrimental effect on the sound quality of the output stage of the amplifier. As they weaken and age their ability to filter extraneous noise becomes less and less. You will hear strange harmonics called "ghost notes" or "following tones." Resistors wear out from heat and high voltage. They need to be inspected as well.


7. Tighten the nuts and bolts. Any part of the amplifier that is held in place with nuts and bolts needs to be tightened periodically in order to prevent strange rattles and hums. Speakers need to room to vibrate, so don't overtighten them.

Repair The Power Supply To A Surveillance Camera

Surveillance cameras can be powered by electricity through an AC outlet, or by batteries that are placed inside the camera. To repair a power supply on a surveillance camera that is not working, the battery contacts may be corroded; if the camera operates via electricity, the power plug on the surveillance camera will need to be evaluated. A few supplies from around the home will be needed, supplemented by parts from an electronics shop. Common household tools will also be needed.


Instructions


Battery Powered Surveillance Camera


1. Open the battery compartment lid on the back or bottom of the wireless, battery-powered surveillance camera -- if there is a screw attached to the lid, remove the screw first with a Phillips jeweler's screwdriver.


2. Remove the battery from inside the battery compartment. Dispose of the battery properly. Do not just toss them in the trash -- chemicals can leak out and cause damage to the environment.


3. Pull the battery clip with the corroded contacts ed out from the compartment. Snip off the two wires attached to the battery clip with wire cutters. Dispose of the battery clip in the trash.


4. Moisten a paper towel in distilled alcohol. Wipe out the inside of the battery compartment with the paper towel. Dip a cotton swab in distilled alcohol. Rub the inside edges of the compartment with the swab. Dispose of the swab and paper towel in the trash.

Charge A Nickel Metal Hydride Battery

Charge your NiMH batteries in a matter of hours.


Nickel Metal Hydride batteries, also known as NiMH rechargeable cells, are a popular choice among consumers who wish to use portable electronic devices. While these devices can use conventional batteries, conventional batteries are not rechargeable, making them a less environmentally friendly option--and, in the long run, more costly to the consumer (NiMH batteries can be recharged hundreds of times). Charging NiMH batteries is a simple procedure that will restore them for use in a few hours.


Instructions


1. Purchase a NiMH battery charger. Prices may vary according to brand name, how long the charger takes to charge the battery cells and how many batteries it can charge at one time (see Resources). Make sure the charger is specific to NiMH batteries, and not NiCD (Nickel Cadmium).


2. Put the batteries into the charger with the polarities (+ and - signs) of the cells lined up with the corresponding sides of the charger.


3. Plug your NiMH battery charger into an available power outlet. Most chargers will have a LED light indicator on them to signal when the charger is plugged in. At this point, the LED indicator should be red, indicating that the charger is indeed receiving power.


4. Take out the batteries once the LED turns green, or after the designated amount of time has passed since plugging in the charger as specified by the user's manual. Use the NiMH batteries until they run out, and repeat the process.

Fix A Tv Screen

Fixing a TV screen is not always possible for a non-professional, but sometimes training is not necessary to fix your device, so long as you have a complete set of troubleshooting steps to be guided by. You will also need a few extra pieces of equipment close by, most notably the TV's remote control and a magnetic coil. Many display problems can be fixed via the cables that plug your TV into the power source, the cable or satellite box, or by manipulating the current video input that is selected for your TV.


Instructions


1. Check the cable power connections on the back of your TV. Is your display dark? Perhaps the power cable simply came out of the wall or the power strip. Sometimes the easiest solutions are the one afflicting your TV, so check this first.


2. Consider the satellite receiver/cable box (this depends on what method you use to receive your television). There are Audio/Video (A/V) cables that run from the back of the cable/satellite box to the back of your TV. These cables are red, white, and yellow in color and plug into sockets that are similarly red, white and yellow. Make sure these plugs are secure in their sockets, and also that the right cables are color-matched with the correct sockets.


3. Eliminate the potential for overheating. Look for any source of heat that is either in very close proximity to your TV, or that is actually touching or laying on top of it. If any such significant source of heat exists, remove the device making the heat immediately. Wait for your TV to cool down and then test it to ensure it is working correctly.


4. Switch the video input on your TV. Outside electronic devices that hook up to your TV make use of A/V cables that plug into different arrays of ports on your TV. Each device usually will thus have its own input for your TV. For example, it is necessary to switch the video input on your TV when switching from regular television to the use of a DVD player. Check to make sure you did not forget to switch the video input back in any such case. If you have, the TV will appear to be blank and not displaying any audio or video. Take the remote control and hit the "Input" button to cycle back through the video inputs and see if this was indeed the problem.


5. Degmanetize the TV. If you have a projection TV, there may be blotches on the display that are a result of magnetization. To rectify this problem, attempt to use a magnetic coil on your TV (see Resources). This coil should be held close in front of the TV and moved slowly in circles in front of the display. Use the coil in this manner and cover the entire area of the display, wait a few minutes, and then check to see if the blotches are gone.

Explanation Of Magnification

Magnification by microscopes unlocked a hidden world.


Telescopes, microscopes, binoculars and reading glasses make small objects appear larger and distant objects appear closer. This ability, termed magnification, relates the size, orientation and distance of the image to the object.


Linear Magnification


Linear magnification is the ratio of the image to the object using either size or distance (linear magnification = image height/object height = distance to image/distance to object). When calculating, assign a negative value to the image. The resulting magnification will then have a negative or positive value indicating a real or virtual image.


Real and Virtual Images


If the linear magnification is negative, the image is inverted and termed a real image. If the linear magnification is positive, the image is upright and called a virtual image. Microscopes are an example of virtual images with the image inverted compared to the specimen. Magnifying lenses exemplify virtual images with both the image and object oriented in the same direction.


Angular Magnification


Microscopes and telescopes produce a virtual image at infinite distance in the eyepiece. Instead of linear magnification, these instruments rely on angular magnification.


Magnification in Microscopes


The total magnification of a microscope is determined by the ocular lens magnification multiplied by the objective lens magnification (magnification = ocular lens x objective lens).


Magnification in Telescopes


Magnification in telescopes is calculated by dividing the focal length of the objective lens by the focal length of the eyepiece (magnification = telescope focal length/eyepiece focal length).

Compare The Panasonic Aghvx200 & The Aghvx200a

Panasonic makes both the AG-HVX200 and the AG-HVX200A, which are professional handheld camcorders. Both of these camcorders offer high quality filming for different situations and filmers' needs.


Features


The AG-HVX200 is the original hand-held camcorder made by Panasonic; it was then followed with a new, more innovated product, the AG-HVX200A. Both cameras come with the following qualities DVCPRO HD quality, variable frame rates, multiple formats, P2 solid state memory cards, 3.5 inch color display, built-in flash and microphone, and resistance to vibration and temperature change. The Panasonic AG-HVX200A, however, offers the additional features of higher-resolution 3-CCD images and improved image performance with 1080p quality HD video. These additional features allow for lower smear and higher S/N ratio. This helps lower background noise, and allows for better filming in low light than the AG-HVX200.


Video


P2 Memory cards are in both the AG-HVX200 and AG-HVX200A. They allow you to shoot and store images on the solid state card. These also allow for easy transfer to computers and edit using any programs such as Apple, Avid, and Canopus. Both the Panasonic AG-HVX200 and the Panasonic AG-HVX200A offer HD quality video for high quality filming. The Panasonic AG-HVX200A films in 1080p, unlike the 720p used with the AG-HVX200. With 1080p you can shoot at 1,920x1080 pixels, allowing for the highest possible resolution for filming in HD and SD.


Prices

Pick Stereo Components

Stereo components have changed a lot over the past few years. They've gotten more sophisticated and they've gotten more complicated. Probably the most important thing to consider when you pick your stereo components is how they make your music sound. You may find that you are sensitive to certain sounds like an over-vibrating bass, so be sure that you listen before you buy.


Instructions


Pick Stereo Components


1. Plan ahead. Make sure that your stereo receiver has enough connections for all of your components.


2. Make a list of the stereo components you need or would like to buy. This will probably include an amplifier, pre-amp, CD player, loudspeakers, equalizer, cassette deck (you may still have a collection of tapes that you want to listen to) and a turntable.


3. Determine your budget. Donald Trump might pick a handcrafted, 27-watt power amplifier with single-ended triode circuitry and silver wire in the windings of the transformers. You'll probably settle for something more affordable as long as it takes a low-level signal and boosts it to a level that can drive your loudspeakers.


4. Do a little research before you pick your stereo components. Thumb through some stereo and audio magazines to find out what the experts recommend. The public library is a good place to start.


5. Learn which components you should shell out more of your hard earned cash for and which ones you can do a little scrimping on. It's recommended, for example, to spend a little more money on a good antenna than to spend a lot more money for a sensitive tuner.


6. Try to buy your stereo components from stores that specialize in stereo equipment. You'll be more likely to get helpful tips from the sales staff than if you buy from a large retail discounter. Buying online will often save you money, but you can't test drive the equipment and returning it may prove difficult.


7. Pick stereo components that come with good warranties and service agreements in case something goes wrong with the equipment. Also, inquire about the store's return policy.

Beat A Traffic Ticket In Phoenix

Getting out of a traffic ticket in Phoenix, Arizona, is no easy matter


With photo-radar cameras installed on many main freeways and traffic cameras installed on almost every busy intersection, there are more than a few ways to earn a driving citation in Phoenix, Arizona. While there is no sure way to get out of a traffic ticket, there are a number of steps you can take to avoid or reduce the effects of a traffic ticket.


Instructions


1. Don't get cited in the first place. The most logical step to ensure that you will not get a traffic ticket in the Phoenix area is to obey traffic laws and avoid the circumstances for getting the ticket.


2. Take defensive driving when offered. Many times, traffic offenders are eligible to take defensive driving courses offered by the state. Taking the course allows you to have the traffic offense and any subsequently added points removed from your driving record. Unfortunately for repeat traffic offenders, the defensive driving course can only be taken once every two years.


3. Go to court and plead your case. Often times, traffic offenders who appear in court are able to obtain a reduction of the fine relating to the violation. When you seek redress in court, the officer involved with issuing you a citation has to appear. Occasionally, the officer will fail to appear in court, which is a good reason to contest the ticket in court.


4. Write a letter to the citing officer. Often times communicating with the officer and pleading your case is an effective way to get the citing officer to drop the ticket against you. Being polite and forthright can go a long way when dealing with a traffic ticket.


5. Contest photo-radar or red light camera tickets. Due to the fact that the cameras photograph the license plate numbers, the ticket will be sent to the owner of the vehicle. If the owner of the vehicle is not the one who committed the offense, the owner can contest in writing to have the ticket removed.


6. Verify that it is you in the picture. If the one who receives the ticket is not the person in the photo-radar or red light photograph, he may contest the ticket on those grounds. Furthermore, sometimes the photograph does not clearly depict the individual driving the vehicle, in which case the ticket may be contested on the grounds that there is not sufficient proof that the one who received the ticket is the one who committed the offense.

Microphone Preamplifier Information

A microphone preamplifier, or preamp, is at the heart of any sound system, be it for recording, live sound, or radio transmission.


Function


The primary function of a microphone preamplifier is to boost the signal of a microphone to line level. This is done through a variable gain control.


Types


A microphone preamplifier can be transistor- (solid-state) or tube-based. Each imparts a different characteristic, or color, to the sound that it amplifies.


Variations


A microphone preamplifier can be purchased individually or in combination with a mixing console. Some individual microphone preamplifiers are modeled after a single channel of a particular mixing console.


Controls


A basic microphone preamplifier will feature phantom power and a variable gain control. Other optional controls include a pad, hi-pass filter and phase reversal.


Connectivity


At the very least, a microphone preamplifier will have an XLR input and output. Many individual preamps also feature a high-impedance input (for instruments) as well as a 1/4-inch TRS input and output for added connectivity.

Automatic Vs Kinetic Watches

Automatic and kinetic watches represent two different eras.


All watches tell time, but some function in different ways. Automatic and kinetic watches represent two different eras of watch manufacturing and two different approaches to reaching one desired effect.


History of Automatic Watches


Before the invention of the automatic watch, all watches had to be wound. According to Watches.net, the first automatic watch was invented by Swiss watchmaker Abraham-Louis Perrelet in 1770. This invention was a true watershed in the history of watchmaking, as almost every watch for the next 300 years could be classified as an automatic watch.


How Automatic Watches Work


In a way, automatic watches work whenever the wearer does. According to Ed Hahn of Timezone.com, automatic watches work by the motion of the watch's internal rotor, which moves whenever the watch and person wearing it move. This rotary motion then winds the mainspring in the watch and causes it to continue ticking.


History of Kinetic Watches


According to Street Directory.com, the first kinetic watch was introduced in Germany by Seiko, a Japanese manufacturer, in 1988. The site goes on to explain that the watches were first called "Auto-Quartz," but the name was changed to "Kinetic" by Seiko in 1997.


How Kinetic Watches Differ


Kinetic watches function similarly to automatic watches. A guide to watches furnished by Kohls explains that a person's movements powers both kinetic and automatic watches, but the process is vastly different. Instead of powering a rotor, kinetic watches have a swinging weight that charges a piece of quartz that vibrates and holds a steady frequency. Once this electrical charge is created, a kinetic watch stores energy in a capacitor.


Benefits of Both Watches


There are benefits to both watches. According to Street Directory.com, kinetic watches need little to no attention, never need winding and are environmentally friendly. However, Kohls points out that automatic watches can be considered more of a novelty and with proper care they can last as long as desired.

Create Stereoscopic Photos

The Holmes stereoscopic viewer is still an effective tool for viewing 3-D images.


Soon after photography was invented in the 19th century, photographers began creating stereoscopic photographs. These photos are made with a camera which has two lenses that simultaneously record slightly different images. When these two images are viewed in a special stereoscopic viewer, the brain merges them into one, so that they appear more three dimensional. You can buy a digital camera that does that these days and special software to view the images in, but it's still less expensive to make analogue stereoscopic images with inexpensive cameras and mounts.


Instructions


Taking the Photographs


1. Load the stereoscopic camera with film. If you are using one of the Holga cameras, tape the back of the camera with gaffer tape to avoid light leaks. Remove the lens caps.


2. Mount the camera on a tripod. Take the camera on its tripod to the scene that you want to photograph. Take a light reading to determine aperture and shutter speed, if applicable. A good scene for stereoscopic photography is one that has some objects close to the camera and some that are far away. This way, the stereoscopic effects will be noticeable.


3. Make the exposure by tripping the shutter. Advance the film two places, because each exposure uses two frames of film. If you are using medium format film with 12 exposures, you can photograph six scenes. Continue to photograph until all the film is used. Roll the film up onto the take-up reel, open the back of the camera, and remove the film.


4. Process the film according to the manufacturer's directions, or take it to a lab for processing.


Printing and Mounting the Photographs


5. Assemble the Holmes stereographic viewer using the kit.


6. Make two small prints for each scene. Mount them, provisionally at first, to a piece of card stock, making sure the left exposure is on the left and the right exposure on the right. Look at them with the viewer. You may have to adjust the distance between the images in order to make them merge correctly.


7. Glue the two prints in place on the card stock. View them through the stereoscopic viewer.

Dispose Of Light Bulbs Containing Small Amounts Of Mercury

Proper disposal of light bulbs that contain small amounts of mercury is very important but can pose health risks if the bulbs are broken. Because mercury is a hazardous substance, proper recycling of mercury-containing light bulbs helps keep this heavy metal from contaminating groundwater. Local and state laws vary on dispose of these type of light bulbs and regulations may be different for a commercial business than for individual households. Recycling facilities are becoming more common due to increased consumer use of compact fluorescent light bulbs, which is one of many types of light bulbs that contain mercury.


Instructions


1. Open a window to ventilate the room, and turn off the central heat and air system. Evacuate the room and ensure no one walks through the broken bulb area. Let the room air out for at least 15 minutes. People are often exposed to mercury by inhaling the vapors after a bulb breaks, so proper ventilation is essential to protecting human health. Do not turn on the central heat and air or close the window until after the spill is properly cleaned.


2. Scoop up large pieces of the bulb using two pieces of cardboard or stiff paper. Make sure you are wearing gloves before handling the broken bulb pieces. Put the large fragments into a glass jar or plastic bag with zipper closure.


3. Use masking tape or duct tape to pick up smaller debris and fragments. Put the tape in the plastic bag or glass jar.


4. Wipe the area clean with wet paper towels or disposable wet wipes. Put the towels or wipes in the plastic bag or glass jar. Put gloves in the plastic bag or glass jar once cleanup is complete. Seal the plastic bag or tightly screw on the lid to the glass jar.


5. Vacuum the carpet where the bulb was broken if necessary. (Remember to keep the gloves on if you are still cleaning.) Remove the canister, and put debris into the plastic bag or glass jar. Wipe the canister with wet paper towels, and put the towels in the container with the rest of the debris. If the vacuum cleaner has a bag instead of a canister, remove the bag and place it with the rest of the debris. Remove gloves, place them in the container and seal tightly.


6. Check your local solid waste management agency to find out where to recycle the broken bulb. If the bulb is not broken, simply place it in a sturdy container, preferably the original packaging. Place the bulb in a plastic zipper bag or a crush-proof container if the original package is unavailable. Some cities or counties provide recycling opportunities for residents and will often accept them through household hazardous collection facilities or events. In addition an increasing number of retail stores that sell compact fluorescent light bulbs collect burned out or broken bulbs. In 2009 a company called NLR began a program that offers free recycling of compact fluorescent light bulbs by providing collection boxes to qualified businesses, schools and cities.

Take Pictures Of Wildlife At Night

Take Pictures of Wildlife at Night


Taking wildlife pictures at night requires proper equipment, including a powerful zoom, since you must stay relatively far away from the animals for your safety and theirs. Additionally, you need to set your camera to take in as much light as possible and have the quickest shutter speed to catch the action.


Instructions


1. Select your hiding spot/vantage point. It should be far enough away from the animal you are trying to photograph that you don't scare it or endanger yourself, but close enough that your camera's zoom can capture it in detail.


2. Go to your preselected vantage point when the moon is out so you have some background light. Take a flashlight to help you see the buttons on the camera and, if need be, to spotlight the animal you are trying to photograph. Use a red light source, since it is less visible to animals. If you don't have a red bulb, you can cover the flashlight with red cellophane paper.


3. Use a camera with at least a 200 mm lens. Digital SLR (single-lens reflex) cameras such as the Nikon D60 or the Canon Digital Rebel enable you to swap lenses from 200 mm to 500 mm. These cameras will give you greater zoom power.


4. Stabilize your camera on a tripod or a sturdy surface such as tree stump. Having your camera steady helps keep images from blurring. Low-light situations need long exposure times to capture all available light, and any shake of the camera will blur the image. Longer focal lengths (zoom) also make the images more susceptible to blurring.


5. Set your camera on "night mode setting." Usually this is indicated by an icon of a moon or stars. You can also set this from your settings menu.


6. Turn off your flash, if night mode doesn't automatically do it. The flash may overexpose your photo or scare the animal away. The flash shoots a burst of light that is most effective for up-close shots, not long-distance shooting.


7. Set your camera to shoot at the absolute fastest shutter speed. You can do this by setting the camera to aperture priority mode or to the highest aperture setting possible. The aperture controls the amount of light the camera takes in; the higher the speed, the more light goes in.


8. Increase your ISO-a measurement of the camera's sensitivity to light-to get more shutter speed, allowing you to freeze the action. An ISO of 3200, for example, will get you exposures of around 1/60 second. Be aware that a higher ISO will introduce more digital noise into your photos.

Revive A Makita 18v Lithiumion Battery

When battery pack tools need recharging the drill bits turn very slowly.


Makita tools with an 18-volt battery pack may include lithium-ion batteries inside. This battery pack contains 12 batteries, 1.5 volts each, wired together to create 18 volts of power. When you are working on a project and your drill begins to turn slowly and not penetrate wood or drive a screw, the battery pack most likely needs charging. Using a Makita fast charger will only take 15 minutes to recharge the battery pack fully.


Instructions


1. Hold the trigger down on the Makita tool until the battery is entirely discharged. The drill will become silent and the tip will quit turning.


2. Grasp the battery pack on the bottom of the Makita tool. Press inward on the tabs on each side and pull the battery pack out of the tool.


3. Plug an 18-volt battery charger into an electrical receptacle.


4. Insert the battery into the charger as far as it will go. A red light will illuminate and a buzzer or melody will play briefly when the battery is in position.


5. Remove the battery by pulling it upward and out of the charger when the light turns green or a buzzer or melody sounds that the battery is fully charged.


6. Unplug the battery charger.

What Bandwidth Does Cingular Use

Just like radio and television broadcasts, cell phone communication is made possible through the transmission and reception of radio waves. Wireless network carriers, such as AT&T, are only allowed to transmit on specific frequency bands in the radio frequency spectrum.


Background


AT&T and Cingular Wireless merged in December 2006. AT&T no longer uses the Cingular Wireless name.


Features


AT&T's wireless network service operates on the GSM, or Global System for Mobile Communications network, transmitting on the 850 MHz and 1900 MHz bands. GSM refers to the standard transmission protocol used by AT&T. Some other U.S. wireless network carriers, such as Verizon and Sprint, operate on the CDMA, or Code Division Multiple Access, network.


Acquisition


The federally mandated switch to digital TV on June 12, 2009, made more room in the U.S. radio frequency spectrum. Some of the bands in the spectrum that were freed up the switch were auctioned off by the Federal Communications Commission. According to an AT&T press release in February 2008, AT&T purchased the right to use part of the radio frequency spectrum in the 700 MHz range, which was previously allocated for use by analog TV broadcasters.

Mini Vs Microsd Card

Mini Vs. MicroSD Card


In recent years the development of cellular phones with their multimedia capabilities has been the biggest influence in a push to create smaller and smaller mass storage media. SD, or secure digital, memory as a format has been a forerunner in this area. But SD has been miniaturized into a format known as miniSD and further so into microSD. The differences between these various formats can seem confusing but crucial when selecting memory to enhance our cell phones and other portable devices.


History


In 1999, a consortium of Sandisk, Toshiba and Matsushita came to an agreement to develop the SD flash memory format. The next year they were part of a larger group named SDA, the SD Card Association. This preceded the release of 32 MB and 64 MB storage devices that were considered large capacities at the time.


By 2003 the market saw the release of the miniSD product which was not only smaller in size but soon became available in 256 MB packaging. Included was an adapter specifically designed to allow the user to insert their miniSD card into a SD slot on their computer, card reader or other device in order to easily move files.


Two years later saw a newer, smaller format called microSD. It is only one-quarter the size of the original SD cards and currently has capacities ranging from 64MB to 32GB (gigabytes) with likely more capacity to come.


Features


At the same time that memory was being developed in smaller packaging, there has been an increase in speed in data transfer rates, measured in Mbps (megabytes per second), which becomes critical in the recording and playback of video files. The increased speed also allows for faster processing times for smart phones and Pocket PCs thus enhancing the user experience.


Significance


The ability to move files around in a portable devices allows for enjoyment, sharing and productivity on the go. Users can record events, work on spreadsheets, get thoughts down and transmit them globally. This is all in addition to the ability to call ahead to inform parties about troublesome traffic conditions.


Warning


Whereas both miniSD and microSD use included adapters to fit into SD slots, they are not usually cross compatible with each other. Today's devices use miniSD much more prevalently due to its smaller size and increased capacities. There are very specific capabilities from device to device in handling memory capacities and data transfer rates. The user is best advised to become familiar with the specifications of their computer, phone, and portable players.


Considerations


Critical to the decision is also in how the memory will be used. Simple text requires little memory per file, music files and pictures can be of significant size, and video can be a serious space hog. Buying the largest capacity available and which is compatible can be fine except that this can easily lead to spending money on unused space and speed. However, it has been observed that a user will most often find a way to fill all available space as they take more pictures, add to their music library or find more applications.

What Does Dpi Mean In Scanners

DPI stands for "dots per inch," but this is just the surface of what DPI really means for getting a good scan of your photos, artwork or documents. You should know about DPI values as well as the real meaning of "interpolated" DPI.


Dot Defined


In "dots per inch," a "dot" is a single point of color. Unlike film or a digital camera, the scan head is just one row of sensors, with each sensor capturing one point. By capturing row after row, you eventually get a complete image.


DPI and File Size


A higher DPI value usually means that more sensors along the scan head are used and that the sensors are capturing more times with every inch scanned. All of this adds up to more information, which in turn makes a larger file. If you know the DPI of where scanned image will go, try to match that value.


For example, a typical LCD monitor will be around 100 DPI, so even a wallpaper image at full size (1280x1024) and in full color (48 bit) should stay under 8MB.


DPI as Two Values


Some scanners describe DPI as two numbers; for example, "1200x2400." Both numbers represent scan quality, but in different ways. The first---usually smaller---number is the number of sensors-per-inch on the scan head. The second number is the calibration of the scan-head motor; meaning how many "steps" per inch the scan-head can be moved. This means the DPI values are expressed like "X by Y." The smaller number, in this case 1200, would be the "actual" DPI for the scanner.


Interpolated DPI


When something is "interpolated," it usually means the same thing as "an educated guess." For image scanning, this means that the scanner software is doing part of the work; filling-in between the dots actually captured by sensors, similar to enlarging a digital photo. The result is usually fuzzy or blurry when compared to the original.


Screen vs. Print


Before scanning, it's important to think about how the image will be used. A typical monitor can be from 72 to 100 DPI, where a typical inkjet printer prints at 300 or 600 DPI. If the image is going to be put on the Web or on a digital picture-frame, it can use a lower DPI and resolution. When a scanned image is going to be included in a project for printing, a higher value should be used.


DPI and OCR


Scanning a printed document---like a report or pages from a book---uses a technology known as OCR. This stands for "optical character recognition," meaning special software that can "read" the scanned document. The program generates text that can be copied into other programs, like a word processor or spreadsheet. OCR is more accurate with higher DPI values, and since only text is saved, the size of the scanned image is not an issue.


Resolution Explained


Some scanner software uses the term "resolution" along with "DPI" in settings. DPI would still mean the actual quality of the scan. The "resolution" determines the total number of pixels that will become an image file. With most scanner programs, both the resolution and DPI settings together will determine the size and shape of the area that will be scanned.

Compare The Canon Xl2 To The Panasonic Aghvx200

When you start shopping around for a professional-grade camcorder, two models that you may come across are the Panasonic AG-HVX200 and the Canon XL2. Since both camcorders are expensive, you want to make sure you are choosing the best product for you. To do this, draw comparisons between the features, price and specifications of both professional camcorders.


Instructions


1. Find the product pages of each camcorder. The product pages can delve into the specifications, features, accessories and support options (see links in References).


2. Check the format that the camera records in. The Canon XL2 is a standard definition camcorder while the Panasonic AG-HVX200 can produce high definition recordings. The Panasonic AG-HVX200 has multiple recording formats, including 1080/60i, 1080/24p, 1080/24pA, 480/60i and 480/24p. The Canon XL2 can record in the 480 standard definition mode.


3. Compare the image resolution for each camcorder. Image resolution can indicate how clear the video recordings will appear during playback. The Panasonic AG-HVX200 and Canon XL2 both can switch between 16:9 and 4:3 for the recordings.


4. Review compatible playback options. The tape format used by the Canon XL2 is Mini-DV. For the Panasonic AG-HVX200, you can place your recordings on the Mini-DV tape or save the images on a SD card or P2 card for tapeless recordings.


5. Look at the prices of the Panasonic AG-HVX200 and Canon XL2. The manufacturer suggested retail price (MSRP) of both high definition camcorders is approximately the same, with many stores selling the devices for about $4,000.

Create A Soft Focus Photo

Soft focus can create a soothing, dreamlike image.


Focus is an important consideration in photography. Soft focus photography creates a picture that is in focus but has an appearance of being slightly out of focus. This can be created in camera using a soft focus lens or in post-production using a soft focus or blur filter. To achieve this in post-production, an advance photo editing program like Adobe Photoshop Elements or similar program should be used. These programs have the different filters that can be applied to create a soft focus photo.


Instructions


1. Turn your home computer on and open Adobe Photoshop Elements. Click "File" in the navigation bar of the program and select "Open" from the drop down menu.


2. Use your cursor to navigate to the folder containing your photos, click the picture you want to open and click "OK" in the bottom right of the window to open the picture.


3. Click the "Effects" tab in the right hand margin of the editing window. Select "Blur" from the list of filters. Select "Gaussian Blur" from the menu, click and drag the icon for Gaussian blur to the open image. Release your cursor and a new window will open up on top of your image.


4. Click and hold the adjustment tab at the bottom of the new window and slide the tab to increase or decrease the amount of blur you want to add to the picture. Release the tab and click "OK" and the program will add the blur to the image.


5. Click "Layer" in the navigation bar of the program and select "Flatten Image" from the drop down menu. Click "File" and select "Save as" to give your edited photo a new name and save it to your computer's hard drive.

Ham Radio Work

Beginning With VHF FM


Ham radios are transceivers that broadcast in all directions. You can use a ham radio to do more than just listen to broadcasts from other radios: Ham radio allows you to be an active participant in conversations with other ham radio operators. Your radio will be able to pick up signals from those other operators, as well as send voice, telegraphy and images to their radios. Ham-radio operators start out using VHF FM. Beginners transmit on one frequency and receive on another. These VHF transceivers require the aid of radio-support groups or clubs to carry the signals from ham radios operating in the VHF FM frequency. The signals are then broadcast from antennas on top of television stations or other commercial structures to increase the range of the signal. Beginners can use their ham radios to speak to anyone in the line of sight, which means the signal is limited. Contacting astronauts with a ham radio is possible, but only when their spacecraft or space station is in alignment with your position on the Earth. This is one of the limitations of line-of-sight transceivers.


Finding Hams


Use other frequencies besides VHF FM to make your ham transceiver more useful. Ham operators can access an array of frequencies, including the microwave band just above AM. The range above the AM band is measured in gigahertz. Find ham-radio operators by searching within the 1.6 to 27 megahertz range. Scan different ranges of frequencies to find ham operators during and after daylight hours. During the day, scan the 15 to 27 megahertz range. At night, the range drops to anywhere between 1.6 and 15 megahertz. The shorter waves are on the higher frequencies, and these will bounce off the ionosphere to anyone receiving ham-radio signals. Non-ham radios, or passive radios, can listen in to ham radio conversations, but their operators cannot participate or respond. The ham radio works well in times of disaster, especially when all other power sources fail.


Other Types of Communication with Ham Radios


Ham radio is capable of operating in Morse code. The benefit of using Morse code is that the beeping signals can still be sent and received when voice messages are unable to be conveyed. This allows ham-radio operators to communicate in even the most difficult situations. Ham-radio operators are part of the digital world: They can access networks of other ham radios via a radio modem. Even more interesting, the ham-radio sound can be converted into digital text on a computer screen. That text is easier to read than some sound transmissions are to hear.

Find The Firewire Port On Your Camcorder

A FireWire port on your camcorder is a very desirable option. FireWire ports and USB 2.0 cables are two of the fastest ways to transfer your digital images to your computer. The first FireWire transfers were around 400 Mbps, and the most recent ones reach around double that figure.


Instructions


1. Find out what kind of FireWire port your camcorder has. Look in the instruction manual to see whether it is a 4-pin or a 6-pin port. They look slightly different with the 6-pin (intuitively) being larger.


2. Look for symbols on your camera. Symbols indicating a FireWire port include a circle surrounded by three sets of bars spreading away from the circle.


3. Look for the shape of the FireWire port. It's close to a rectangle with either 4 or 6 pins in the center. It has one end slightly tapered, making a 6-sided shape that is close to a rectangle.


4. Look under covers. Sometimes FireWire ports are covered by a protective plastic guard to keep them clean and functioning. Most of the time, these are marked by the symbol indicating "FireWire."

Build A Pbx System

You can set up a private line for multiple phones on a PBX system.


To make a Private Branch Exchange system or PBX, you will need to install an Ubuntu server on your computer. The Ubuntu server is a command line program. A PBX system is a system for telephones that allows for certain calls to be re-routed to another telephone. Systems like this are useful in business settings and other professional settings where multiple private phone lines need to be installed and used.


Instructions


1. Log into the Ubuntu system as the root user and open the command prompt. Type the text "sudo password root" into the command line and enter your regular password for the user password when prompted. Press "Enter."


2. Enter the password that you would like to have for the system and press "Enter." You will be asked to reconfirm the password change by the system prompting you to enter the new password two more times.


3. Copy the following text into a terminal window to prepare a build environment: "apt-get install build-essential speex libspeex-dev gsm-utils" and press "Enter." Afterwards, type "libgsm1-dev libgsmme-dev libgsm1 libgsm-tools" and press "Enter." Afterwards, type "libncurses5-dev ncurses-term linux-headers-2.6.24-19-generic" and press "Enter." Finally enter "libncurses5-dbg doxygen subversion" and press "Enter."


4. Download the Digium asterisk source packages.


5. Extract the packages by typing in the code "tar -zxvf asterisk-1.4.21.2.tar.gz && tar -zxvf zaptel-1.4.11.tar.gz" and pressing "Enter." Afterwards, type in "&& tar -zxvf asterisk-addons-1.4.7.tar.gz && tar -zxvf libpri-1.4.5.tar.gz" and press "Enter."


6. Build and install the source packages by typing "cd libpri-1.4.5" and pressing "Enter." Press "Enter" after you type in each code to go the next line. Type "make," "make install" and press "Enter." Type "cd ../zaptel-1.4.11," "make clean" and press "Enter." Type "./configure" and press "Enter." Type "make menuselect," "make install," "make config," "cd../asterisk-1.4.21.2," "make clean" and press "Enter." Type "./configure," "make menuselect," "make install," "make samples," "make progdocs," "cd ../asterisk-addons-1.4.7," "make clean," "./configure," "make menuselect," "make install, "make samples" and press "Enter." Type "cd ../asterisk-gui," "./configure," "make," "make install," "make samples," "cd /root," "mkdir packages" and type "mv *.gz /root/packages/" and press "Enter." You will get the message "echo INSTALLATION COMPLETE PLEASE CONFIGURE WEB GUI."


7. Save the file as "atsetup.sh" once you have copied the text into the terminal window. To run the file as an executable, you will run the file in the command as "chmod+x astsetup.sh."


8. Finish the installation so that the user interface will run. Edit the files "/etc/asterisk/http.conf" and "etc/asterisk/manager.conf."


9. Change the settings for "/etc/asterisk/http.conf" by setting "Enabled" to "yes" and set "Enable Static" to "yes." Set the asterisk HTTP so that it can respond by entering in "0.0.0.0" into "binaddr." Set "bindport" to "9000" and set prefix to "asterisk."


10. Change the settings for "/etc/asterisk/manager.conf" by setting "Enabled to "yes" and change "webenabled" to yes." Set "Admin" to whatever you would like for the username. Set read to "system,call,log,verbose,command,agent,user,config" and set write to "system,call,log,verbose,command,agent,user,config." The IP address is the IP address of the PBX box.


11. Restart your computer and go to "http://IP-of-pbx:9000/asterisk/static/config/cfgbasic.html," where "IP-of-pbx" is the IP address of the PBX box, and you will see the Internet interface where you can log in to create and set up the extensions for the private phone lines. The setup on the computer is now complete and it is time to connect the PBX phones to the computer so that they may be routed correctly. There are three different methods for setting up the phones.


12. Set up your PBX system using a professional telephony card by connecting each phone to a double adapter and plugging the other end of the double adapter into the telephony card. Split and connect the end of the adapter into the PBX unit. After you have connected the PBX unit, connect the different phones to the unit. Connect the remaining phone lines into the telephony card on the back of the computer.


13. Set up up your PBX system using a multi-channel sound card by using a double adapter to split the phone lines so that one part of the line goes to the PBX unit and connect the PBX unit to the specific telephones. Plug a line from the PBX unit into the multi-channel sound card. Install the hardware of the multi-channel sound card and connect any remaining phone lines into the multi-channel adapter.


14. Set up your PBX system using splitting the lines using a splitter adapter and connecting one end of the line to the PBX unit and the other end of the lines to the telephones. Plug the line into the sound card of the computer. If you have more than one phone line to connect, connect the lines to a USB adapter that is connected to your computer.

When the time comes to purchase new stereo speakers you may be able to save some money by having the broken speakers repaired. Follow these steps to find someone to repair your stereo speakers.


Instructions
