Often times, people find themselves needed to get a screen shot of something that's on their computer. Students, employees, or end-users may need to show others what was on their screen as part of a report, demonstration, or example of something that went wrong (in the case of end-users who need to email their tech support an example of a problem they're experiencing). You can do this easily, with a few key strokes.
Instructions
1. On the screen you'd like to save, hold down the "Shift" key on your keyboard, and then press the "Print Screen" key.
2. Open up Microsoft Paint (or similar program).
3. In Microsoft Paint, click "Edit" on the top tool bar, and choose "Paste" from the drop down menu. In MS Paint, you can now edit your screen shot as needed. You may want to "highlight" certain areas, or use arrows to indicate to your reader what section of the screen you're referring to.
4. Click on "File," on the top navigation bar, then choose "Save as" from the drop down menu.
5. Microsoft Paint will default to wanting to save the file as a bitmap, but by clicking on "Save as type" below the file name, you can choose "jpg."
6. Use your saved screen shot as you would use any other jpg file.

The Nikon D40 is an entry level digital single lens reflex (DSLR) camera. It was released in 2006, and followed in the footsteps of the Nikon D50, but at "a significantly lower price point," according to Digital Photography Review." The camera has a number of features that appeal to the advanced amateur photographer. One such feature that will appeal to any photographer who is shooting action or moving subjects is the camera's ability to shoot in "Continuous" mode. In this setting the camera will record pictures at a rate of 2.5 frames per second.
Instructions
1. Hold the camera in your hand and install a freshly charged battery and empty memory card. Turn the camera on by rotating the switch located by the shutter release.
2. Press the "Menu" button on the back of the camera and use the round "Four Way" selector button to toggle to "Custom Setting Menu." From here toggle to "04 Shooting Mode" and select "Continuous." This will set the camera to continue to take pictures while you hold the shutter release down.
3. Hold the camera to your eye and press the shutter release to take pictures of a moving object. If the pictures are not sharp, make sure the camera's auto-focus is set to "AFC-C Continuous-Servo." To set this, press the "Menu" button, use the "Four Way" selector button, and toggle to "Custom Setting Menu." Select "02 Focus Mode" and change the focus mode to "AF-C Continuous-Servo AF." In this mode the camera will track and focus on moving subjects.
4. Press the shutter release to take pictures. If the camera stops taking pictures, look to see if the memory card is full. The Nikon D40 will take an unlimited number of images in "Continuous" mode up to the storage limit of the memory card. If the card still has room, check to see if the camera is set to record RAW images. In this format, the camera will shoot in burst of nine frames, and then will not take any more until they have been saved to the card.

Radio-frequency Identification (RFID) chips are available as U.S. Food and Drug Administration (FDA)-approved, implantable devices for hands-free identification of such individuals as children, students, and prisoners. RFID has long been used to identify cattle and pets.
State Bans
In January 2008, California Governor Arnold Schwarzenegger signed into law SB362, joining Wisconsin and North Dakota in banning forced implantation of "unique identifiers" like RFID in children, students, prisoners, state employees, among others.
Public Advocacy
Anti-RFID advocates claim that major corporations, such as Wal-Mart and Home Depot, and governments with RFID-enabled passports "plan to track your every purchase and track your every move."
Voluntary Implantation
Voluntary implantation is fairly common. The Attorney General of Mexico and 18 members of his staff allowed the VeriChip device to be implanted in their arms for security access and faster access to medical records. A Barcelona, Spain, beach club piloted RFID implants for patrons, allowing them to buy alcohol and services without using cash.
Privacy
Contrary to popular belief, RFID chips contain no personal information; they contain single numbers, which are matched to a database where private information resides. Without the database, the number on the chip is meaningless.
Cancer
Implantable RFID is suspected of causing cancer, but proof is questionable. A September 2007 Associated Press story quoted a pathologist who claimed RFID induced malignant tumors; but more than15 million tags implanted in animals have yet to be linked to tumors.

The Bose Wave stereo system is a small stereo known for its high-quality sound. While this stereo may look minuscule compared to a more elaborate, full sound system, it is capable of producing sound that belies its small body. The Bose Wave system has a slot for one CD, but you can buy add-ons such as Bose's Wave multi-disc changer and a connecting system for an iPod. Using the system requires setting it up in an ideal location and playing the music you enjoy.
Instructions
1. Determine which Bose Wave system best suits your space and listening needs. Bose produces different Wave systems, geared toward rooms of different sizes. The Wave system is designed for use in small spaces, while the Wave Acoustic series is ideal for use in large rooms and outdoors.
2. Position the Bose Wave stereo where you will enjoy listening to it and where it is easily accessible. The Wave stereo measures roughly 4 by 15 by 9 inches, so it will fit in relatively small spaces. The Wave Acoustic stereo is larger, at 11 by 18 by 7 inches, and will require more space.
3. Do not place the Wave where it is in danger of being exposed to water or any liquid. If you wish to use it in the kitchen, keep it away from the sink. Also, the rear of the stereo has vents that must not be blocked.
4. Plug the small end of the Bose Wave's power cord into the rear of the device and plug the other end of the power cord into an electrical outlet. Unwind the power cord and straighten it to its full length, as the Wave's FM antenna is built into the cord.
5. Explore the different functions of the Bose Wave stereo by pressing their corresponding buttons on the remote control. The "On/Off" button provides power to the device; the "Time" buttons allow you to enter the correct clock time; the "FM/AM" and "CD" buttons enable the corresponding functions; and the "AUX" button enables your iPod if it is plugged in. Explore other buttons such as the volume control, "Seek/Track," "Tune" and stereo presets.
6. Insert a CD into the Wave stereo's CD slot to play a CD. Press the "CD" button on the remote control and choose your desired play mode by pressing the "Play Mode" button repeatedly.
7. Press the "FM/AM" button and press either of the "Tune" arrows to find the station of your choice. If you wish to enter that station into the system as a preset favorite, press and hold one of the six "Presets" buttons for at least one second.
8. Turn off the Bose Wave stereo when it is not in use.

Over the years, film cameras have changed more on the outside than the inside.
A film camera still operates on the same basic optical properties that the first models did in the first half of the 19th century. The one major development has been the innovative design of the single-lens reflex (SLR) camera, which includes an interior mirror.
Film Advance
The first cameras could hold only one piece of film at a time, but since the creation of roll film, all film cameras need a film advance system. This interior apparatus usually consists of two spools, one at each side of the inside of the camera. The spools are needed to move the film forward after an exposure has been made.
Shutter Mechanism
The shutter mechanism remains closed most of the time. When a picture is taken, the shutter is opened for a brief span of time, allowing light to expose the film. Modern shutters can be adjusted for the size of the opening, as well as the duration the shutter remains open. In many cameras, the shutter is located right behind the camera lens.
Single Lens Reflex Cameras
The newest innovation is the movable mirror that can be found in all SLR cameras. When not in use, this rectangular mirror sits between the lens and the film. The shutter has also been modified, so the person behind the camera can look through the lens during the viewing process. When the picture is taken, the mirror must first swing up, and then a sliding shutter, located near the rear of the camera, allows light to expose the film.

Nikon's D200, introduced in 2005 and discontinued in late 2007, is a professional-grade digital SLR. The Canon 5D, introduced in August 2005 and discontinued in 2008, was one of the more sought-after cameras for landscape photographers. The two both offer excellent performance, but there are significant differences.
Canon 5D
Sporting a 12-megapixel full frame sensor and capable of shooting three frames per second, the 5D hit the market with a retail price of $3,999, but eventually, during its heyday, was priced at $2,499. The 5D offers excellent color rendition and shutter speeds of between 1/8000 of a second and 30 seconds. The 5D has ISO speeds of 100-1600, plus boosts of ISO 50 and 3200, and has nine autofocus points.
Nikon D200
The D200 has a 10-megapixel APS-C-sized sensor and ISO speeds of 100-1600, with boosts in one-third steps above 1600 up to 3200. The D200 can shoot five frames per second; it retailed for $1,699,
Sensor Size
One of the prime differences between the 5D and the D200 is sensor size. The 5D has a full frame sensor, meaning the sensor is the same size as 35mm film. The D200 has a cropped APS-C sensor. The 5D sensor is bigger, so not only does it have more megapixels, it also has bigger pixels, resulting in less noise in the image. Noise looks like freckles in the image, instead of true color.
A full frame sensor also doesn't have a telephoto crop with a lens, so a 24-70 lens truly is a 24-70 focal length, whereas on an APS-C sensor, which crops the image, the 24-70 is equivalent to a 36-105. APS-C sensors makes it harder to take wide-angle shots. The focal length is the zoom on the lens; lower numbers equal a wider angle, while higher numbers equal more telephoto.
Frame Speed
The 5D was never intended to be a camera for sports or action, though some photographers used it that way. The D200, however, with its rate of five frames per second, could take all but the most demanding action shots.
Body Size
Both the D200 and 5D have magnesium alloy bodies, but the 5D weighs a fraction less than the D200, at 895 grams (31.6 oz.) vs. 920 grams (32 oz.). The 5D body measures a little bigger at 152 by 113 by 75 mm (6 by 4.5 by 3 inches) than the D200 body,147 by 113 by 74 mm (5.8 by 4.5 by 2.9 inches).
Self-Timer
Both the 5D and D200 have a self-timer; the 5D's maximum is 10 seconds, while the D200's self-timer can go to 20 seconds.
Uses
The 5D, with its full-frame sensor, is an ideal landscape and portrait camera. It has excellent color and resolution, and the full-frame sensor gives you more options for panoramic shots and wide-angle shots indoors. The 5D will also do better than the D200 in low light, due to having more megapixels and bigger pixels on the sensor, although the D200's autofocus is a little faster in low light thanks to its autofocus assist light.
The D200, with its faster frame rate, is a better camera for high-speed action and sports. Though the D200 can only capture 30 consecutive JPEGS (vs. 70 for the 5D) and takes more time to write to the memory card, the faster frame capture is better for sports.
One other advantage to the D200 is it has a built-in flash, good for snapshots. The 5D does not have a flash, and so it requires an external Canon speedlight.

The Chameleon Mega is a digital video camera that was released in 2007 by Largan Inc. As of September 2011, Largan's Web domain has expired. Technical support is not available online, but you can still obtain installation drivers for your Chameleon Mega camera online. Once you install the Mega's drivers, you can install the camera and connect it to your computer with the USB cable that comes with the device.

Liquid crystal display, or LCD for short, is a type of screen display technology that was once used primarily for computer monitors and laptop screens but has evolved into a common format for larger TVs. One useful function of LCD TVs, especially large HD LCD screens, is that they can double as a large workspace for a computer, or be used to display videos or to play games. Connecting a computer to an LCD TV is relatively simple, but it requires the proper hardware to be purchased in advance.
Instructions
1. Plug one end of your video cable into your video card. An S-video cable may require an extra adapter to link the video card to the normal S-video cable. (This will likely come with the video card.)
2. Plug the other end of the cable into your TV, using adapters as appropriate. If your video card and TV have the same type of plugs, you will not need an adapter. If not, you may need to use two cords with an adapter between them. You may also be able to plug an adapter right into your video card or TV, and just use one cord to connect them.
3. Turn on the TV and computer.
4. Turn the TV to the proper video channel. Depending on the TV, you may have several video channels, or even several of the type you are using to connect the computer, which you will have to cycle through to get to the right one.
5. Set up screen sharing in your video card's control panel. When the TV is hooked up properly, it should be automatically recognized as a second display device, and may even be working just after starting up your computer. If not, find the control panel for your video card by right-clicking on your desktop. Within the panel, look for an option to set up multiple displays or screen sharing. This will enable you to turn the TV into a clone of your computer desktop, or to set it in dual view mode, which creates an extension of your workspace.

The Canon Rebel 2000, introduced in October 2001, is a model in Canon's popular line of entry-level 35mm single lens reflex (SLR) cameras. Canon continued to use the name "Rebel" as photography moved from the film era into the digital age. While the Rebel line is at the entry-level point in film and digital, the camera is packed with features and provides good value for a photographer's first SLR camera. The power switch for the Rebel 2000 is integrated into the exposure mode dial.
Instructions
1. Hold the camera in one hand and make sure it is loaded with two fresh lithium CR2 batteries. These batteries go into the molded hand grip on the camera.
2. Locate the exposure mode dial on the top left of the camera. Here you will see a red camera icon. When the dial is in this position, the camera is turned off.
3. Turn the dial to any of the 11 shooting modes for the camera. When you turn the dial to select the shooting mode, the camera will be turned on at the same time.
4. Hold the camera to your eye, compose the picture and press the shutter release to take the picture. The Canon Rebel 2000 has a built-in film winder that automatically advances the film so you can take the next shot right away.

Astrophotography is a type of photography that involves taking pictures of astronomical phenomena. Since the late 1800s, astrophotography has proven an essential tool for astronomers, who use photography to capture objects in outer space that cannot be viewed by the naked eye with a telescope. Astrophotography also attracts a number of amateur enthusiasts, who record images from the night sky for aesthetic rather than scientific purposes.
Instructions
Instructions and Tips
1. A basic piece of equipment for the beginning astrophotographer is a webcam.
Choose a webcam. Webcams are surprisingly effective for astrophotography and an excellent option for beginners. Though they present problems with low resolution and image quality, their quick acquisition speeds allow them to capitalize on fleeting moments of clear skies that a point-and-shoot camera can easily miss. "Clear seeing," or good visibility in the night sky, is an important factor in photographing planets--which is where you will start as a beginning astrophotographer.
2. Modify the webcam for astrophotography. Remove the camera's objective, which comprises the lens and lens holder. Using an adapter, align the camera into the focuser of the telescope.
Consider buying a webcam and adapter made specifically for deep sky imaging. This may require some research as astrophotography has a large and dedicated fan base, many of whom have designed and marketed special equipment for their needs. Figure out where your specific interests lie, and find the webcam/adapter combo best suited to your purposes.
3. Install an astro-imaging software driver for your webcam. There are a number of freeware options available, like Peter Katreniak's K3CCD Tools. Most of these programs use the same methods to capture images, so try them out and decide which interface you prefer.
4. Before you begin to photograph, get acquainted with the software and learn the control panel. Make sure that the camera connects and recognizes the software.
Choose the resolution you want and set the acquisition speed. Specify a default directory for the night's session; it's best to keep all your photographs in one place. Establish a default naming convention, so that you can easily find your images later. Make sure you have plenty of disk space.
5. Find an area with few clouds and little light pollution--you want as clear a sky as possible. Mount your telescope to an equatorial mount (a mount that follows the rotation of the earth and sky). Use the eyepiece to select the view you want.
6. Remove the eyepiece from the telescope and insert the webcam. Focus--and then let the webcam do its work for a while. A webcam's autoexposure is generally sufficient to obtain decent images.
Beginners should consider photographing the moon before moving on to objects that are farther away.

The Nikon Coopix L21 and L22 are ideal for on-the-go use.
The Nikon Coolpix L21 and L22 are part of a series of ultra-compact Nikon digital cameras. They are ideal for basic use in everyday situations. There are subtle differences between the two models, especially in regard to photograph quality and zoom capability. The L22 has more advanced features than the L21. However, the L21 is smaller in size and has better battery life.
Photo Quality
Megapixels are the resolution, or quality, of a photograph. The higher the megapixels, the higher the photograph quality. The Nikon L21 has 8-megapixel quality. The Nikon L22 has 12-megapixel quality, making it far superior in photograph quality than the L21. Furthermore, the L22 has a larger LCD screen for viewing photographs. The L22's LCD screen measures three inches, while the L21's LCD screen measures 2.5 inches.
Zoom
A digital camera can have two types of zoom: optical and digital. Optical zoom utilizes the actual lens to get closer to the subject. Digital zoom digitally enlarges the subject and is of lesser overall quality than optical zoom. Both the L22 and L21 have 3.6 optical zoom. However, the L22 also has 4x digital zoom, thus it is able to zoom in closer to subjects.
Size and Weight
Due its additional features such as more zoom and megapixel quality, the L22 is larger in size than the L21. The L22 measures 3.9 inches high, 2.4 inches long and 1.2 inches wide. The L21, on the other hand, is slightly smaller. It measures 2.3 inches high, 2.4 inches high and 1.2 inches wide. The L22 is also heavier than the L21. The L22 is 7.6 ounces, while the L21 is 6 ounces. Both are relatively lightweight, but depending on how often you use the camera and where you want it to take it, you may prefer a lighter and smaller camera.
Battery Life
Both cameras use two AA batteries. Rechargeable batteries can be used but they cannot be charged in the camera. Even though they both use the same batteries, the L21 has better battery life. The L21 can take approximately 280 shots before the batteries need to be recharged or replaced. The L22 can take approximately 240 shots.
Color
The L21 and L22 are each available in different sets of colors. Both are available in champagne silver. The L21 is also available in brown and pink. The L22 is sold in black, blue and red.

Adjust your monitor display to reflect your personal preferences.
There are several ways to adjust the size of the text and images on your computer screen, in addition to the window size. While font and text size are often a matter of personal taste, increasing the size of text, icons and other images also makes things easier to see, reducing eye fatigue. The best way to adjust the size of your screen is through the control panel on your computer or laptop. Adjusting the screen resolution this way can help you personalize your settings and make working on your computer more comfortable.
Instructions
1. Right-click on an empty portion of your desktop and left-click on the "Personalization" or "Properties" tab. Alternatively, go to the "Start" button and click on "Control Panel."
2. Click on "Display Settings."
3. Move the "Resolution" slider from left to right to increase resolution. Increasing resolution will allow more items to fit on the screen, but they will be smaller and sharper; lower resolutions allow fewer items to fit on-screen because they are all larger, but they may have blurred edges. The horizontal and vertical measurements are in pixels. LCD screens usually work best at their "native resolution" -- usually the highest available.
4. Hit "Apply" after the resolution adjustment. These changes will be permanent until you change them.
There are a variety of home audio systems available for the average consumer. One type of audio system is the Bose sound dock. The Bose sound dock is one of the most expensive, but quality audio systems on the market. Over time, however, a wire or connection inside the Bose sound dock may come loose causing the audio to stop. Taking apart a Bose sound dock is very simple and only requires minimal tools.
Instructions
1. Remove any MP3 player from the Bose sound dock.
2. Disconnect all the sound cord plugs for the various speakers from the rear of the Bose sound dock. Unplug the Bose sound dock.
3. Flip the Bose sound dock over on its top side. Most Bose models have all the screw heads on the base of the Bose sound dock.
4. Unscrew the six to eight screws fastening the bottom and top halves of the Bose sound dock. The number of screws and whether you will use a flat head or Phillips screwdriver will vary from model to model. Put the screws in a safe spot so they don't get lost.
5. Slowly pull the base from the top plastic cover. There will be wires attached from the base electric board to the top touch display and buttons. The cords are long enough to set the top down beside the Bose sound dock base.
Whether you have old negatives or slides, you need to digitize. If you prefer shooting images on film and do not want to bother with a darkroom, transferring film to digital is necessary. You can do it with a few easy steps and a minimum of computer equipment. And, apart from developing your own film, you no longer will need smelly chemicals to process your images.
Instructions
1. Clean your negatives or slides. You can do this by using compressed air to blow off dust and debris, then using a film cleaner and lint-free cloth. Starting with clean film will reduce the amount of time you will need to spend fixing images in your photo editing software.
2. Place your slides or negatives in the film carriers provided with your flatbed scanner. You will need a higher-end flatbed scanner to do this rather than most consumer-level scanners, because you need to have a light source in the scanner's lid. These cost a bit more, but you need to shine a light source through the transparencies to scan them. Flatbed scanners intended for film scanning typically have film carriers with them or as options. Film carriers hold the negatives or slides flat and straight. This also will reduce the work you will need to do to "fix" your digitized images.
3. Scan your film images at the highest resolution possible. The better the original resolution, the better the finished images will be. Follow the directions for the software that came with the scanner to increase the resolution. It is different with different scanners.
4. Open your photo editing software and then open your batch digital image file to begin separating your images. If they are negatives, the scanner probably inverted them to positive images, but if it didn't, you can do that yourself in the software. In Adobe Photoshop, for example, go to "Image," then "Adjustments" and then "Invert."
5. Use the "Selection" tool to trace out each image, copy the image, start a new file and paste the image. Then save it as a digital image in TIFF format. While JPEG will take up less room because JPEG files are compressed, TIFF provides better image quality.

Operating a Grundig television is not a complex task, requires no formal training, and isn't a process for only electronic whiz-kids to attempt. Everyday display adjustments, A/V input switches, and external device connections can be made by you in your spare time with no headaches or stress, as long as you have the convenience of the Grundig television remote on hand and a little understanding of the Grundig television's menu system and A/V and Zoom functions.
Instructions
1. Ensure that all the connections have been correctly made, because if they have not, normal operation of your Grundig television will not be possible. This includes checking to make sure the power cable for the Grundig television is not loose, and ensuring that the A/V cables are both securely in place and also hooked up to the correct sockets. In a standard A/V (audio/visual) setup, these cables are red, white and yellow and hook up to sockets on the back of the Grundig television and the back of your cable or satellite box that are color-coded. So, the red cables (there is one of each on each end of the A/V cable) should only go into the red-colored sockets, and so on.
2. Peruse and make changes under the Grundig television's menu system. Hit the "Menu" button on the Grundig television remote (or on the face of the TV itself) to access the menu. Scroll through using the up/down arrows on the remote/TV face to make changes to menu options. For instance, under Clock settings, you may set the correct date and time, or under "Brightness", adjust the brightness of your Grundig television.
3. Utilize the "Zoom" button on your Grundig television remote. This function will allow you to change the ratio of the television program currently being displayed. For instance, it can stretch the program so the picture takes up the entire width of your screen (in the case of a Grundig wide-screen TV), or zoom in multiple times to further enhance (or distort) the picture on screen.
4. Connect external devices such as DVD players and game systems to operate these devices in conjunction with your Grundig television. These devices will hook up to your Grundig television via additional A/V inputs on the back of your Grundig. There are high-def and standard-def hookups for these devices, depending on your specific Grundig model, and making sure the correct A/V input for each device is used to maximize picture quality is essential, so check the manual that ships with your specific Grundig for more.
5. Cycle through video inputs and acquaint yourself with the input system. Cycling through video inputs will allow you to switch between displaying audio and video feeds from different external devices, such as the aforementioned game systems and DVD players. Use the "AV" button on your Grundig television remote to cycle through these inputs.

Lavalier mics are wonderful tools that can provide all the recording and amplification benefits of a traditional microphone while remaining hidden. These are helpful in interview situations, documentaries, reality television and hidden camera types of situations.
Instructions
1. Clip the microphone to the subject's clothing, preferably the lapel of a coat, somewhere along the neckline. Point the mic upward toward the subject's mouth. Try to hide the mic but don't allow anything to block the mic's screen.
2. String the attached transmitter down the subject's body. Attach the transmitter by clipping it to the back of the subject's pants, skirt or other garment.
3. Press the power button to turn the transmitter on. It's screen should light up and display a channel. Make sure it is set to the correct channel. If not, set it as needed.
4. Plug the receiver into the camera. Press the power button to turn it on. Again, the screen should light up and display a channel. Make sure it's the same channel as the transmitter.
5. Put the headphones on and plug them into the camera or audio mixer. Have your subject speak. Adjust the audio input levels on the camera or mixer as needed.

A polyphonic ringtone is a music-based ringtone that offers more complexities than a single-tone ring, but not as much clarity as an MP3 ringtone. Individuals may wish to convert an MP3 file into a polyphonic ringtone in order to personalize cell phones that may not be able to support the MP3 format.
Instructions
1. Insert a music CD into your computer. Use Apple iTunes, Microsoft Windows Media Player, or the music management software of your choice to extract the song that you wish to convert. Drag the MP3 file to your computer desktop.
2. Launch your MP3 conversion software that utilizes the LAME audio compression codec. Various companies and software developers offer open-source software that utilizes this codec. For the purpose of this example, we will use RazorLAME (see Resources to download).
3. Open the MP3 file from Step 1 in the audio compression software. In RazorLAME, click "Choose Files" and select the MP3 file. Some software may also support drag-and-drop importing. If you are unsure of open an MP3 file in the audio compression software you chose, consult the user manual.
4. Encode the software as a WAV file. Select "WAV" from the drop-down menu of available conversion file types supported by your audio compression software. This list is typically found on the main interface screen of the audio compression software, or in the "Options" menu at the top of the screen. In RazorLAME, it is listed under "Options."
5. Click "Encode." Your audio compression software will then convert the MP3 file to a polyphonic ringtone WAV file. Depending on the size of the MP3, this process may take several minutes.
An auxiliary input on your car stereo allows you to play your iPod or other audio device through your car speakers. This is much better than some other adapters that play your device on a car radio station. An auxiliary input adapter will keep as much of the sound quality intact as possible. Unfortunately, not all car stereos have auxiliary inputs, but here's what to look for.
Types of Auxiliary Inputs
RCA connectors
Two basic types of auxiliary inputs are found on most car radios. The most common is the 3.5 mm jack, which this is the same plug you will see on your iPod, almost every MP3 player and many other audio devices. The other type is the RCA jack. The RCA-type connector is most common on aftermarket radios, and uses 2 separate cables, one for the left stereo channel (typically white) and another for the right stereo channel (usually red). The cable that is used to connect an iPod or MP3 player will have a headphone type plug on one end (which will connect to your iPod/MP3 player) and your vehicle's connection type on the other.
Sound Quality
Auxiliary input adapters are good ways to ensure your device sounds as good as it possibly can. The auxiliary input takes the low-level headphone output from your MP3 player, iPod or other device and uses the car stereo's built-in amplifier to boost the sound to a higher level.
Connect Your Device
Most auxiliary inputs are very easy to use. The most common method is to connect an iPod or other MP3 player to the car stereo. Locate the auxiliary input in your vehicle and purchase the cable suitable for your vehicle's connection (either an RCA-type or 3.5 mm cable) in a length that works best for your application. Plug one end into the iPod or MP3 player. Plug the other end into the auxiliary input. Press the "auxiliary" button on your car stereo and your device should play through your car speakers.

Repairing a projector can be done with a few common tools.
Projectors are devices used in some dedicated home theaters as a video source. These units can be very expensive, and repairing is usually more economical than replacing. Also, most projectors require routine maintenance causing users to eventually learn repair certain parts after they have become worn or obsolete. Repairing a projector takes a few common tools and can be done by users with little to no experience.
Instructions
1. Remove the projector from the ceiling mount if necessary. Place the projector on a surface upside down to access the disassembly screws. Use a phillips or slot-head screwdriver to remove the screws and remove the projector's casing.
2. Flip the unit right-side up and locate the projector headlamp. Remove the lamp by unscrewing any mount screws and pulling the unit out of the slotted port. Dispose of the lamp properly; they typically have a high levels of mercury. Install a recommended lamp replacement and secure the lamp mount back into place. Use the canned air to remove loose dust from the unit.
3. Locate the main exhaust fan, typically found in the front or rear of the unit. Remove any screws securing the fan to the projector's casing and unhook the molex power adapter. Replace the exhaust fan with a manufacturer-recommended fan and install into place. Use the canned air to blow any loose dust outside of the unit after installation.

Whether you're an amateur or a professional photographer looking to get a bit creative with your pictures, try creating your own inexpensive lens filters. A lens filter works to change the color or reduce the light your photos are exposed to. Creating your own lens filter is not difficult or expensive, and you may even find some of these tools lying around the house. There are surprisingly many options to create your own lighting effects. Don't be afraid to try something new.
Instructions
1. Buy a roll of slide film at a photography store and have it developed unexposed. This will give you a thin, clear film that's perfect for making your own filters. If you can't find slide film, use cellophane.
2. Cut the slide film just slightly larger than your lens.
3. Purchase a few, inexpensive bottles of methyl blue, yellow or red from a pet supply store.
4. Put a little water in the pie pan, and add a few drops of the methyl blue or any other color that you like. Mix the solution so it is even in color.
5. Dip the cut slide film into the solution and let it sit for about five minutes. Use tweezers to pull it out and flip it upside down to cover both sides. Let the film dry.
6. After the film is dry, use masking tape or a rubber band to attach the filter to your lens.

Personal computer speakers sometimes leave a lot to be desired when it comes to sound quality. In a just few steps, you can hook up large stereo speakers or even car stereo speakers to your computer and get better sound.
Instructions
Placement of the Speakers
1. Place your speakers where you want them in a room before connecting the speaker wires. That way, you will know exactly how much speaker wire you need.
2. Measure the distance between the speakers and the speaker connection on your computer and cut the appropriate length of speaker wire from the spool. You may need to splice the wire leading from the back of the speakers to a longer piece of speaker wire to make the necessary connection.
3. Next, cut off the end of the speaker wire that will connect to the speaker jack on your computer. Splice it with the wire and connector of a small stereo headphone jack.
4. Before securing the wire with wire nuts and electrical tape, connect the subwoofer wires into the speaker wire and to the adapter wire.
5. Be sure your computer is turned off. Plug the speakers into the speaker jack on your computer. Reboot the computer. Wait until your operating system and start-up settings have loaded before opening the volume control properties on your computer operating system.
6. Once you have opened the volume control properties, adjust each of the volume settings to the desired level. You also may need to adjust the volume and equalizer settings in each media-player software application you use.

Dry mounting your digital photos might fit your budget and creative sensibility.
You've taken beautiful photos that you'd like to put on display, but you don't want to pay high prices at a framing shop. Dry-mounting is a technique that uses heat-activated dry mount tissue to bond a photograph to mount board. No water, glue or tape required. And you can do it at home, without incurring the expense of having a professional mount your photos.
Instructions
Preparing Materials
1. An everyday clothing iron will melt the mounting paper.
Turn your iron on to a setting between 175 and 230 degrees Fahrenheit. You want it warm enough to melt the mounting paper, but not so hot that it damages your photograph. Start on the cool side and continue to get warmer if needed. The iron should be clean and scratch-free to avoid damaging the photograph. Do not use the steam feature on your iron -- the water will damage your photo.
2. Place your blotter paper on your work station to protect your photograph. Place the photograph face down on the blotter paper. Then place the dry mount paper on top of the photo. Lightly press the tip of the iron to the center of the mount paper, just long enough for it to adhere to the back of the photograph.
3. Remove the blotter paper and flip the photograph right-side up, so it's now sitting on the mount paper. Using the ruler as a guide, cut the mount paper to the exact size of your photograph with the x-acto knife. If the mounting paper sticks out beyond the edges of the photograph, it will show in your final presentation. If it is too small, the edges of the photograph will curl up.
4. Cut the mount board to your desired dimensions using the ruler and the x-acto knife. If you are able to purchase the mount board in the size you need, skip this step.
5. Measure the placement of your photo on the mount board using the ruler. This will allow you to place the photograph on the board within an even border. You can get creative with the width of the border, but a good starting point is 1 to 1.5 inches on all sides. A tip to make your final presentation more appealing: make the bottom edge of the border wider than the other three sides. Add an extra 1/2 inch or more on the bottom. Once you know your dimensions, lightly mark the four corners with a pencil.
Photograph Mounting
6. Place your photograph -- with dry mount paper still attached to the back -- on your mount board within your pencil markings.
7. Place your blotter paper over the photograph to protect it.
8. Lightly press the iron along the photograph, just long enough to heat the dry mount paper and adhere all three pieces together. It may take time for the heat to reach the mount paper under the blotter paper and photograph. Start in the center and work the iron toward the edges to ensure a smooth finish.
9. Remove the blotter paper to reveal your freshly mounted photograph. Erase any pencil markings still visible on the mount board.

A whole new world of unique and interesting images awaits underwater photographers.
Exploring new surroundings can be a very compelling activity for many photographers, amateur and professional alike. A whole new ecosystem exists in the world's lakes and oceans, from the natural beauty of a coral reef to the unexplored shell of sunken ship. Underwater cameras and camera housings can be very expensive to purchase. If you are trying underwater photography for the first time, with a little bit of work you can easily construct a waterproof case for your digital camera.
Instructions
1. Select an airtight storage container usually used for storing food leftovers. Select a container as close to the size and shape of your camera as possible.
2. Cut a hole in the lid of the container for the lens, making sure the hole is larger than the diameter of the front of the lens housing. You will create a waterproof cover for this hole.
3. Cut a clear piece of plexiglass or plastic to cover the lens opening, ensuring it is larger than the lens opening.
4. Position the plexiglass over the opening. Using a 1/16-inch drill bit, drill one hole in each corner of the plexiglass, ensuring the drill bit goes through both the plexiglass and the container lid.
5. Cut the foam gasket to match the size of the plexiglass cover, and to match the lens opening.
6. Place the foam gasket over the lens opening. Place the plexiglass on top of the gasket, and screw from the inside of the lid to attach the pieces together. Fill the holes on the front of the plexiglass cover with a drop of bathroom silicone. Then seal the plexiglass cover by running a bead of silicone around the edges. Set it aside and let it cure according to the silicone instructions.
7. Mount the camera by cutting Styrofoam to match the base plate of the camera. Trim so the Styrofoam fits snugly into the container. Secure the camera in place by using two elastic bands over the top the camera and bottom of the Styrofoam base. Ensure the elastic bands do not come in contact with any of the camera's controls.
8. Place the camera, with fully charged or new batteries and a memory card, and Styrofoam assembly into the container. Trim a small tubular piece of cork to match the size of the shutter release. Mount the cork to the inside of the container using contact cement. You want the cork to be long enough to come in contact with the shutter release, but not to depress the release. Position and glue the cork, and test.
9. Attach the container lid, and seal the closure with bathroom silicone, letting it cure as per instructions. You're ready to use your new housing.

Mastering the use of parametric equalization takes some time and practice.
The parametric equalizer (EQ) is a valuable audio tool that takes its name from its ability to adjust the various parameters of sound. These parameters are frequency, bandwidth, and gain, according to Astralsound. Whether you're getting started recording or performing music, or simply looking for a powerful tool to customize your home audio system, examining a basic tutorial for parametric EQ is a key step in getting that perfect sound.
Instructions
1. Connect your parametric equalizer to your audio equipment, or enable the virtual parametric EQ from the audio mixing software you are using. If you are using a multi-channel EQ to mix vocals and instruments, assign a channel of the parametric EQ to each audio input source and label them accordingly. Before starting your audio device(s), set your parametric EQ to a neutral configuration by adjusting the gain control to 0 dB, the bandwidth (or Q) control to midway through its range, and the frequency to the low end of its range.
2. Turn on your audio device and assess the initial sound. You can boost the sound levels by adjusting the parametric EQ gain control. Using the bandwidth and frequency controls, you can modify your boosted sound, "shaping" it as desired by raising or lowering the frequency and bandwidth in relation to the gain level. Gain is the overall boosted sound level, and frequency is the sound "envelope" which contains bandwidth, or the amount of octaves over which the sound signal is affected by gain, reports Astralsound. Experiment with these controls in relation to each other to get a sense of how they affect each other.
3. Control extreme high frequencies--often the squealing of feedback--and very low frequencies (humming or buzzing) by using the high and low pass filter sliders. These filters, according to Recording Review, can be set to a certain measurement of Khz or Hz (kilohertz and hertz, respectively) to manage extremes of sound on the high and low end. For instance, setting a low pass filter to 5 Khz will cut all frequencies above 5 Khz, and setting a high pass filter to 100 Hz will eliminate all low frequencies below this setting, enabling you to manage high-end feedback and low-end buzzing or humming.
4. Mix the EQ of each audio device armed with an understanding the way that the parametric settings affect different types of musical instruments and vocals. For instance, electric guitars achieve a clarity of sound with a low pass filter setting of 5 Khz, and a full bottom end with a high pass filter setting of 125 Hz, according to Ethan Winer's The Art of Equalization. Drums such as snares, kicks and toms have a desirable "slap" at low pass settings of 2 to 3 Khz, while the high pass for each typically ranges from 60 Hz to 200 Hz.
5. Read the owner's manual for your parametric EQ. Since each equalizer model is different, your parametric EQ unit or software may boast special features which you can use to your advantage. For instance, preset gain, frequency, bandwidth, and high and low pass filter levels come standard with many parametric EQs, and can help you get started with a framework of settings you can work with to get the specific sound you're looking for.

All types of batteries work by creating electric current through the movement of charged particles between two electrodes, the cathode/positive terminal and anode/negative terminal. These two electrodes create an electrochemical reaction through an intermediary substance called an electrolyte. The real differences between battery designs are in the specific electrochemistry used in a battery design, namely what the cathode, anode and the electrolyte medium are made of.
Zinc Manganese Batteries
The most common Energizer batteries are the non-rechargeable alkalines, such as the AAs, AAAs, Cs, Ds and 9 volts. These are based on zinc-manganese electrochemistry. The anode is made of zinc powder, and the cathode is made of manganese dioxide. The electrolyte is made of potassium hydroxide.
Nickel Hydride Batteries
Energizer's rechargeable batteries are an improvement on the nickel cadmium battery. They substitute a hydrogen-absorbing alloy for cadmium in the anode, but the cathode is still nickel oxyhydroxide. The electrolyte remains potassium hydroxide as well.
Lithium Ion Batteries
Energizer also has a line of lithium ion batteries. These batteries use graphite for the anode, and the cathode is made from a lithium oxide. The electrolyte is composed of solid lithium salts mixed in an organic solvent.
Winning a complaint dispute with Verizon Wireless can be a challenge if you are not prepared. Verizon Wireless, like all cell phone companies, want to retain your wireless business, but they also do not want to lose money. If you have a complaint or dispute, follow these simple rules to getting what you want.
Instructions
Before the Call
1. Before you ever contact Verizon Wireless with a complaint or dispute, you should follow a few simple steps first. The first step would be to specifically identify what you want. When you call Verizon Wireless, you want to have a clear goal in mind, and be able to thoughtfully, and firmly state why you deserve said goal. Know what you want before you call.
2. The next step before you call is to have all applicable dates, mistakes, payments and bills from Verizon Wireless right in front of you so that you will be speaking to them from facts. Your memory may be strong, but having cold, hard facts in front of you is much better.
3. Have a compelling, professional complaint ready and rehearsed. Practice with a friend what you are going to say, and why. Most complaints and disputes are lost before you even pick up the phone.This is due to a lack of being able to convey what it is that you want, and not knowing why you deserve it.
4. Anticipate the roadblocks. Most people know that Verizon Wireless will have people on the other line that want to save the company money. This means that they are going to try to avoid being at fault. If they are at fault, you need to be able to explain why and overcome any roadblocks the customer service representative may put up.Think about this before dialing.
During the Call
5. When you call the customer service department of Verizon Wireless, politely ask for the correct department to handle your complaint or dispute. Once you get to the correct department, ask for a supervisor. This will allow you to speak with someone that can actually do something about your problem. If they need to call you back, take careful notes about when and who will call you. This will be very important later, and you will be glad you took down the information.
6. Once you are on the phone with a supervisor, politely and firmly explain the situation to them. Do not be harsh or hostile in any manner. Be very polite and nice, and take careful notes of everything the supervisor says. Make sure that you let the supervisor know that you are taking notes. This lets them know that you are keeping careful records and will keep them on the straight and narrow. Verizon Wireless is a business, and every business has good and bad supervisors. This is just in case you get a bad one. Ask for their name, and note the date and time.
7. Once you have explained the problem, ask the supervisor directly for what you want. Make sure that the request is reasonable, and then be quiet. Many customers shoot themselves in the foot by saying to much. Make your request and then let the supervisor answer. Generally, if you are requesting an adjustment to your bill, or any other request that will cost Verizon Wireless money, they will try to avoid doing so. When this happens remain calm, and ask for the next level of supervisor.
8. As you move up the chain of supervisors, continue to be civil, and take very good notes. With each supervisor, let them know who you have spoken with already, and make sure they are above that person or department. Often, supervisors will send you to other supervisors of the same rank. Make sure this is not the case by asking.
9. If your complaint is valid, most supervisors will not let it escalate above them. If they have the power to fix your situation, they generally will. This is a built in power play. Your asking for the next level of supervisor kind of forces the hand of the supervisor you are speaking with automatically.
10. Finally, if all else fails, inform them that you are going to change wireless carriers if this problem is not resolved. Generally, they will not want this to happen. If your complaint or dispute is valid, they will fix it. Do not be afraid to stand up for what is right. Verizon Wireless wants your business and in a volatile wireless market, they need your business. Make them earn it.

6. Turn the PT Cruiser's terrestrial radio to the station frequency shown on the Starmate 4 receiver to hear the Sirius audio through your existing stereo system.
7. Call the Sirius customer service number displayed on your Starmate 4 receiver and written in its user manual. Doing so activates your Sirius satellite radio service. You can also activate your service from the Sirius website.
Rechargeable batteries, batteries that can be recharged and used over and over, are a modern marvel of electronic power. With millions of battery-powered cameras, computers, personal media players and other electronics in circulation, the demand for batteries grows continually higher. While early rechargeable batteries quickly discharged and became cumbersome to use, modern nickel-metal hydride (NiMH) batteries exemplify a dramatic improvement in battery technology.
Environmental Benefits
As technology has enabled progressively smaller personal electronics, devices have become increasingly smaller and more reliant on battery technology. With millions (if not billions) of personal electronics in use today, tremendous volumes of batteries are discharged and discarded every day. When NiMH batteries completely discharge, they can simply be charged back up and used again; this reuse of battery resources removes some of the burden of landfills, as millions of slowly decomposing batteries can quickly overwhelm garbage collection services. As a secondary effect, reusing batteries reduces the need for trips to the store to purchase replacement batteries, helping clear the air of vehicle emissions.
Low Discharge Rate
Users of personal electronic devices quickly realize that batteries must be replaced with some measure of frequency because they quickly expire. Because of their design, NiMH batteries are often rated at 1850 mAh or higher, enabling them to outlast their standard alkaline counterparts. In addition, NiMH batteries may retain their charge for considerably longer times than even alkaline batteries, giving them a longer "shelf life" between uses.
Size and Weight
While some batteries are bulky and others are unexpectedly heavy, NiMH batteries pack a significant electrical punch in a compact, lightweight package. The size and weight of NiMH batteries make them ideal for personal electronics, and allow the batteries to be packaged in a variety of forms to power a broad spectrum of electronic devices. Some devices, such as the Apple Macbook Air, use NiMH technology to restrict the weight of an entire notebook computer---including the battery---to under three pounds. As technology develops, rechargeable NiMH batteries may become even more lightweight, making more devices portable.
Types
Nickel-Metal Hydride technology allows NiMH batteries to be packed into a broad spectrum of shapes and sizes. Common applications of NiMH require batteries in AAA and AA form, though larger rechargeable batteries such as C and D sizes are also available. NiMH technology can also be found in tiny watch and hearing aid batteries, battery packs for specialized electronic devices and proprietary internal batteries like the ones found in Apple iPod personal media players. Cellular and home cordless telephones use NiMH batteries, as well as laptop computers and other portable devices. The technology has also been explored for use in electric vehicles like the Chevy Volt, though the success of large-scale battery deployment has not yet been established.
Warning
Although NiMH batteries are far more environmentally friendly than their alkaline counterparts, they do eventually expire and must be discarded. To minimize environmental impact, some companies offer recycling of NiMH batteries. Taking advantage of this program keeps the batteries out of landfills entirely. When NiMH batteries are discarded, they should not be burned, prodded or punctured as doing so may cause a rapid, explosive discharge of any remaining electrical capacity. In addition, users of NiMH batteries should use caution to recharge the batteries only in approved chargers, and to never use commercially available batteries in unintended applications.

You can place your script directly in your eyeline with a homemade teleprompter.
At one time, teleprompters were mostly a mainstay of network television production studios, but with the development of cheaper production equipment and diverse journalism outlets, teleprompters have found a life in lower cost production situations. Whether you perform news segments for public cable channels or demand a visual script for "on location" journalism, a teleprompter is a key tool. You can create a teleprompter with basic, store-bought materials.
Instructions
1. Cut the 1 inch-by-2 inches plank into eight equally sized pieces.
2. Combine four of the plank pieces, with the narrow sides of the planks facing downward, to form a square. Nail the pieces together using two nails at each end. Make a second square with the remaining four plank pieces.
3. Secure one side of the hinge, with two nails, to the middle of one wooden square. Combine the two wooden squares by nailing the other side of the hinge to the other square. The apparatus should now function like a mouth.
4. Center the two-way glass on one of the wooden squares, and glue the glass to the wood on all four sides.
5. Open the two wooden squares to approximately a 60-degree angle. Maintain this angle by diagonally driving a nail on each side of the wooden square that does not contain the two-way glass.

There are a number of factors that will have an effect on image quality in DSLR cameras. Some factors can be controlled by the photographer, including exposure, ISO and lens selection. Others are specific to the camera being used, such as sensor size and processors.
ISO & Noise
ISO is the camera's sensitivity to light. In bright settings a low ISO number (100-200) is typically used. In low light the camera requires a longer shutter speed, or increased aperture size, allowing more light to hit the sensor. However, some pictures may require a fast shutter speed---photos of indoor sports, for example. In those cases the photographer can increase the camera's ISO setting to compensate for the low light. A higher ISO results in the creation of digital noise, those blue---pink and purple specks that appear in pictures---generally viewed as an undesirable by-product.
Bigger is Better
We spend a lot of time thinking about the pixel count in digital cameras. And it is true that pixel count will have an impact on image quality. You should also consider the actual physical size of the sensor in your camera. Most DSLRs have one of two sensor sizes in them: a full frame sensor---equivalent to a 35mm negative---or a smaller sensor, often referred to as a cropped sensor. The effect these sensor sizes have on the image quality relates to image noise and dynamic range. Larger sensors also have larger pixels, giving them the potential to produce lower image noise and increase the dynamic range of the picture. Dynamic range refers to the range of color tones the sensor can capture.
Exposure
Exposure is another factor that will affect the image quality in DSLR cameras. Exposure is the amount of light that travels through the lens to the digital sensor. The amount of light is controlled in two ways, shutter speed and aperture. The shutter speed determines how long the shutter stays open, allowing light to hit the sensor. The lens aperture is the size of the opening that light travels through, from small to large. If you have a slow shutter speed then you need a larger opening, and vice versa. While many cameras have sophisticated auto-exposure programs, under certain conditions those programs will not always provide the correct setting. If an image is under- or over-exposed too much, the picture will not be usable.
Lens Quality
Whether you are using a film camera or digital camera, the lens you select will affect image quality as well. Long before light from your picture appears on the digital sensor, it has to travel through a number of glass or plastic elements inside the lens. Using cheaper lenses can result in a permanent effect on the quality of your photos. Cheaper lenses may result in poor autofocus or have chromatic aberrations---a purple fringing in your photos. They may also have difficulty with maintaining perspective on walls.
Digital Processors
DSLRs are as much computers as they are cameras. And, like computers, the digital processors contained in them can have a significant impact on image quality. The current Canon processor is the DIGIC 4 (Digital Imaging Core). It boasts quicker processing time compared to the DIGIC 3, but more importantly it has improved noise reduction in high-ISO images. The most recent DSLR to use the DIGIG 4 is the Canon 7D, which has a maximum ISO setting of 12,800.
In the 21st century, technology has rapidly emerged as an important component of teaching, learning and reform in America. Although a valuable asset, technology alone cannot teach skills needed for students to progresses in school. Teachers still must teach and model within classroom settings in order for them to effectively deliver information to students. Technology is a great tool that reinforces what teachers teach and a great way for individuals to continuously learn.
History
Technology has been married to education for decades, beginning with the creation of the first vacuum tube-based computer in 1946, with the help of multiple universities. Ten years later technology was playing an even bigger role, strengthened when Russia launched their satellite Sputnik into space. During this time, schools were still abiding by the system that highlighted the teacher as the facilitator and only source students received information from within the classroom. Even so, the launching of Sputnik jump-started educational reform in the United States, which brought in money from the National Defense Education Act and began providing schools with technology.
Features
Technology is vital in education, because it offers students at all levels of schooling multiple alternatives to learn faster. It is a valuable asset to young, adult and special needs students. For young students, technology will dramatically decrease their chances of struggling as they move ahead through school. In addition, children that become acquainted with technology show major improvements in their reading, writing and math skills. Adults benefit profoundly from technology as well. Technology allows adults to continuously learn, develop strong skills that will be helpful in almost any career and transition into refined citizens. For special needs students, various types of software will not only benefit them mentally, but physically as well. Depending on the deficiency, the actual movements and manipulation of joysticks, mouse pads, and other hand held devices could strengthen their hand and eye coordination and other physical weaknesses.
Significance
Merging technology and academics within the classroom to enhance academic content provides learning tools for students, in addition to direct instruction. Teachers can mold technology to help reinforce numerous subjects, as well as structure it to accommodate multiple learning styles. Because everything as of 2010 is in some way connected to technology, students, even those on the elementary level, already have some indication of how technology has the ability to enhance learning.
Warning
Although integrating technology into the classroom has many promising results, potential challenges exist as well. One of the major challenges is that students have a tendency to get bored quickly and drift off onto other websites. They must be fully aware of what the teacher expects of them, as well as the outcome of what could go wrong if they do not use technology wisely. Moreover, technology could be a challenge to a teacher if she has not had a sufficient amount of the training that comes from web-based professional developments.
Prevention/Solution
The teacher must plan strategic means for merging technology within the classroom. If she doesn't, she will not cater to the target areas that she may be trying to strengthen. This will merely mirror the technology of the past, when a teacher allowed a student to use an encyclopedia to gather information. Teachers have to communicate to students exactly what their learning goals and outcomes are, so that they can capitalize on their lessons. As for teachers, staff development sessions in technology are vital, because they will be better equipped and have the confidence needed to implement technology-based lessons.
