Installing the Video module is the same as installing any other Drupal module. You can manually install the module, or you can install it using the administration panel.
Transistors employ semiconductors to amplify the strength of electrical signals. They are used to boost the signal power of everything from audio to power itself. But like any other electrical device, transistors have a limit to the amount of power they can receive. If a transistor receives more voltage than it can handle, the power will likely fry the transistor. The Darlington 2SB1558 transistor is rated for 140 volts. Avoid frying your 2SB1558. Build a protection circuit with a 140-volt fuse to protect your transistor from voltages that are too high.
The Display Data Channel, developed by Video Electronics Standards Association, is a collection of digital communication protocols, that allow the display to communicate its supported display modes to the adapter. DDC enables the host to adjust parameters such as gamma, brightness and contrast based on the data received from the monitor. In Ubuntu, you can monitor the DDC using the xresprobe utility and get information on everything from video card model and available resolutions to monitor screen size and gamma.
Three-sided fireplaces, commonly called peninsula fireplaces, add a dramatic touch to a home. Because the fire within can be viewed from three different sides, peninsula fireplaces are often used as room dividers or islands in large living spaces. Peninsula fireplaces are more than just a pretty face, though. When you add a blower to a peninsula fireplace, they can serve as a secondary heat source. You can fit blowers to both gas and wood burning prefabricated peninsula fireplaces with a minimum of technical know-how.
The Dodge B-series vans debuted back in 1971, after the elimination of the A-series lineup of vans, which lasted from 1964 through 1970. In 1981, Dodge added the “Ram” name to the full-size van line up. The 1994 Dodge Ram B250 came standard with a 3.9-liter V-6 engine that pushed out 175 horsepower. The upper ball joints on the B250’s front suspension are an odd setup, as they are a screw-in type, as opposed to a press-in type. This makes removing and installing an upper ball joint on the 1994 B250 a more straightforward task than most other vehicles of…
A microcontroller, otherwise known as an embedded controller, is a type of computer that contains a single integrated circuit. Microcontrollers run a single or multiple tasks preprogrammed into the onboard memory. A logic level representing one or zero on the electronic logic circuit supplies the power to the microcontroller. Additionally, different logic families or gates represent the voltage levels using different logic voltage, current and interface capabilities.
Scanners, radios and telephones sometimes use a voice scrambling technology known as "speech inversion," intended to provide extra security for conversations. If you need to communicate with someone who uses this technology, you will need to descramble the speech inversion. Although commercial scrambling and descrambling units are available, you could opt to build your own descrambling circuit.
A computer bus is a port that is used as an interface between a computer's central processing unit or CPU and the peripherals, such as a keyboard and mouse, that are connected to it. A bus enumerator is a driver or program that loads built-in drivers and Peripheral Component Interconnects or PCI bus drivers that are used by the computer to run a device.
Nothing lasts forever, but Jeep Cherokees may come close. It's not unusual to see them in full use with well over a quarter of a million miles on the odometer. Engine options in 1986 included a base four-banger and a V-6 sourced from the Chevrolet division of General Motors. Cooling system performance is vital to engine longevity, and system maintenance and repair is easily accomplished, thanks to a simple design and a roomy engine compartment. Replacing the fan clutch requires only basic hand tools and a modicum of information.
Older automobiles typically have a single, belt-driven fan that is used to move air through the radiator. If you have an older car and you need to drive it in stop-and-go traffic, this type of fan may be inadequate to prevent overheating. A secondary electric cooling fan can be installed to assist the cooling system. An electric fan installed in front of the radiator is referred to as a “pusher” fan while one installed on the engine side of a radiator is known as a “puller” fan.
Gable fans provide a suitable solution for attic ventilation for many homeowners. A gable fan is simply one that is installed in the triangular portion of the part of the wall below the two descending slopes of a roof. A gable fan is designed to vent the attic area of a home, but it can be used to vent the attic portion of a garage, or it can be used to vent a garage in which no crawl space is located above the rafters.
Scrolling allows you to navigate long Web pages or documents using your mouse, the arrow keys or the scroll bar on the right side of the screen. Normally the screen moves fluidly, allowing you to keep track of your place. A screen that jumps sharply, producing a ripple effect, makes it difficult to see and control. This behavior typically occurs due to a corrupted or out-of-date graphics card driver and is usually corrected with the download and installation of the newest version for your installed card.
A sequential light timer is designed to turn a series of lights on and off according to a particular pattern. Sometimes there are only two lights in the sequence, and sometimes there are many more. These sequential timers are relatively easy circuits to build for people experienced in building their own electronics, as modified circuits and capacitors are used to achieve the effect.
The Puppy Linux install files are located online, but you can download and store them to many different types of portable media. Once stored there, you can activate them by setting your BIOS to boot from the particular device you have stored them to. You can also download individual install files from the Puppy Linux Repository.
The Compaq Evo N115 is a notebook computer with an AMD Athlon or Duron processor and a memory capacity of up to 384MB. Although upgrading the memory of the Evo N115 does not allow the computer to meet the minimum requirements for a modern operating system such as Windows Vista or Windows 7, it can improve performance in older operating systems.
Direct3D is an application that aids in the rendering of three-dimensional images. Microsoft developed Direct3D to compete directly with OpenGL, another gaming application programming interface. Direct3D is a component of the DirectX application interface. Although designed as a Windows application, you can also run Direct3D on other operating systems when used in combination with Wine open-source software.
When a laptop becomes unresponsive to input from either the mouse or the keyboard, this is commonly called a “hang” or a “freeze.” Laptops may hang for a variety of reasons, ranging from incorrect power management settings to operating system issues to hardware issues. Determining the likely cause of hanging behavior helps you determine how to resolve it.
With some sewing machine oil, a sewing needle and a screwdriver, fix the loud noise that emanates from a loud fan on a video card. Loud fans can ruin gaming and audio on your computer, because the sound overpowers speakers in some systems. After you oil the fan, replace the video card in the computer to return the system to a quieter running volume.

An LED chaser circuit is a common, eye-pleasing use for LED lights. This type of circuit consists of a row of LEDs that blink in sequence and then repeat. Special integrated circuits, or IC, microchips control the sequencing of the blinking. An electronics hobbyist can pick up the appropriate ICs and most of the other required parts at local electronics hobby shops for less than $2 each.
Emerson has been manufacturing fan motors, desk fans and ceiling fans since the 1890s. Their ceiling fans cover a wide range of styles, designs and colors to coordinate with virtually any decor and lifestyle. It’s important to install your Emerson ceiling fan properly so that it functions efficiently and safely.
The notation "Vee" is used to signify the negative power supply rail, or ground, in an operational amplifier (op-amp) circuit, or to label the power supply pins on an IC (integrated circuit) pin-out diagram. It derives from notation used in transistor circuits. Vee notation is commonly used in circuit diagrams, electronics texts and data sheets; however, there are also alternate forms of notation.
Ford uses a thermal-type fan clutch to regulate cooling fan speed in the 1985 F-150. At low temperature, the clutch slips to reduce fan speed. As the engine heats up, the clutch increases the fan speed to increase the amount of cooling air drawn through the radiator. Fan clutches eventually wear out and either slip or drag, causing overheating or overcooling, respectively. You can use common tools to replace the fan clutch.
The blower motor resistor for your 2001 Dodge Dakota plays a very important role in regulating the heating, ventilation and air-conditioning system. The resistor restricts the flow of electric current to the blower motor, depending on the position selected on the fan speed dial switch. A faulty blower resistor will cause one or several restricted fan speed selections to stop working.
A window valance neatly caps a window, adding not only style but energy efficiency depending on the type of valance. A valance constructed of hard material, like plywood -- with four sides and an open back and bottom -- is called a cornice board. Cornice boards are frequently padded with batting and covered with fabric to match or complement window treatments. Install a hard valance with a closed top directly above your drapes to keep warm, heated air from being pulled down through the open tops of draperies and onto cold window surfaces, according to Michigan State University Extension.
When the type of work you do with a MacBook suggests that you may benefit from increasing its random access memory, you will need to consider the pros and cons of upgrading the laptop’s RAM. Apple makes two MacBook models: The MacBook Air and the MacBook Pro, with default memory ranging from 2GB in the MacBook Air to 4 GB in the MacBook Pro, as of the date of publication.
Installing new components in your computer can sometimes cause hiccups with existing components. If your speakers aren't working after you install a graphics card, the computer may be trying to produce sound off the graphics card instead of your existing sound card, or your drivers may be out of date.
The retro graphics in the sandbox computer game "Minecraft" may not look complex; as your "Minecraft" constructions grow in complexity, however, your graphics card may struggle to render them. Less-powerful graphics cards, such as those found on laptops, may require significant processing time to create new areas of the "Minecraft" world. The longer it takes to render the graphics in an in-game area, the less immersive the game becomes. To improve game performance in these cases, lower the graphics quality settings in "Minecraft."
Chevy Trailblazers come with a fan clutch installed; this clutch forces the radiator fluid through a water pump, cooling the engine. However, you may prefer to have an energy-efficient, electric fan instead of a clutch. These fans use much less horsepower than other types of radiator fans. To install an electric fan in a Trailblazer, the clutch fan will need to be pulled out first.
The 2006 Dodge three-quarter-ton and one-ton pickups equipped with the Cummins 5.9-liter diesel engine use a serpentine belt to drive accessories such as the coolant water pump and fan, power steering pump and air-conditioning compressor. Chrysler Corp. recommends accessory belt inspection every 15,000 miles or 12 months, whichever comes first. To inspect, twist the belt by hand and look at the ribs that run longitudinally on the contact side. Small cracks in the ribs are acceptable but any missing sections of the ribs, fraying or glazing are causes for belt replacement.
"Flight Simulator X" is a commercial video game developed by Microsoft Game Studios that allows players to pilot a wide variety of airplanes. Like most computer video games, "Flight Simulator X" allows players to edit its video settings to ensure optimum graphics quality. If you are dissatisfied with the graphics quality while playing "Flight Simulator X," you can improve it by updating your system and tweaking the game's settings.
When two different kinds of metal are submerged in an acid bath, there is often a flow of electric current called galvanic current. Electrons are leached out of one metal into the acid, and then deposited from the acid onto the other metal. This process can be useful as when metal pots are “galvanized” to prevent rusting. It can also be destructive – because it destroys the metal from which the electrons are leached. Boats are often susceptible to the destructive effects of galvanization because they contain several metal components that are submerged in water that may be acidic –…
Building an oscilloscope for display of wave forms or a logic analyzer to show digital logic states may sound like a big project. Thanks to USB-based hardware and associated software available from a variety of companies, building an oscilloscope and logic analyzer based on a PC can take less than an hour. Feature-rich software can take much longer to learn than bench-top models, since it provides a wide variety of recording and analytical functions for both analog and digital signals. Some USB-based devices provide spectrum analyzers and other options as well, and even operate over networks.
A nice hot bath or long shower can relax you and wash away the day’s tensions. All that tension can come running back if you find mildew sprouting in the room. Stay relaxed by installing a fan in the room, either in the main portion or directly over the bathtub.
The Hitachi GDR-8050L hard drive is most commonly found in Xbox consoles manufactured in September, 2004 and later. The video game news website Xbox Scene states that the hard drive is compatible with writeable and rewritable DVDs, often referred to as DVD+R and DVD-RW, respectively. However, users have reported that the drive cannot recognize data on some recordable CDs, often referred to a CD-Rs. You can take apart a Hitachi GDR-8050L to attempt a repair, such as fixing a stuck disc tray or replacing the spindle motor, but you will void the warranty.
Many modern Hampton Bay ceiling fans, like the 7067R, are not directly connected to your home’s power supply. Instead, they are connected via a receiver, which allows you to use the ceiling fan with a remote control. However, installing the receiver into the ceiling fan can be a bit tricky since there are some electrical connections to be made. Once the receiver is installed, your fan will work off of the remote.
Your computer's motherboard is designed to produce an error code if the computer is unable to start because of a hardware issue. The primary purpose of a computer's internal speaker is to beep in the event of an error. However, the internal speaker also beeps when the computer starts without an error. Some users, finding the noise unpleasant, choose not to connect the internal speaker when assembling a computer, so many motherboards also include LED lights that blink when an error occurs. Watch the blink pattern to determine the cause of the error.
Audio and visual equipment cabinets tend to accumulate a lot of heat because of the high energy use of this electronic equipment per square inch. This heat becomes trapped in closed-in cabinetry and requires effective venting. Keeping the environment cooled increases the life span of the equipment and helps it to function properly. Vent fans can be installed in a number of sizes and shapes, but the basic installation process is the same for the majority of them.
Dell's Inspiron 537ST desktop computer provides a versatile computing experience with a customizable tower in a personalized colored chassis. With your choice of a variety of powerful processors, the 537 allows you to customize your system to suit your computing needs.
