The Honeywell Comfort Basic RTH110B is a basic model of thermostat used to control the heating and cooling systems of your house. Unlike more advanced models, the RTH110B cannot be programmed to a schedule. The thermostat requires two AA batteries for power; an indicator on the display helps you keep track of how much power is remaining and tells you when to insert fresh replacements.
Deep-cycle batteries provide an alternative to cranking batteries for applications requiring deep discharging and long service life. Structurally, they differ from conventional car batteries in that they use thicker, more antimony-charged plates. Given a desirable balance of factors, deep-cycle batteries can achieve efficiencies as high as 98 percent, be cycled to as low as 20 percent charge and last as long as 20 years. These factors include charging and discharging conditions, operating temperature, capacity, load and maintenance. Deep-cycle batteries typically provide power for forklifts, boats and backup power systems.
Ranging from chimps to puppies, the Hasbro FurReal family includes over 150 products. Among the FurReal collection is the newborn baby bird macaw parrot. This parrot chirps to let you know it is ready for a bottle or flaps its wings to indicate it is meal time. Another parrot previously offered by Hasbro was the talking "Squawkers Macaw." Although discontinued, this parrot is often sold at secondhand stores, yard sales and online auctions. Program the baby bird to chirp when it is hungry or thirsty, while the adult macaw will talk and mimic your voice.
Nickel Cadmium (NiCad) batteries are a popular source of energy for electric, hobby-grade, radio-controlled (RC) vehicles. These compact rechargeables offer long run times and pack a lot of energy in a relatively small package. By learning how to test your NiCad battery pack, you can ensure that you are driving with optimum performance.
Whether you are using solar battery cells for a small-scale school project or for a commercial-scale project to power a small town, knowing the solar charging time can help you determine how long the solar cell panels will need to be exposed to sunlight. Since each solar cell has the ability to generate its own current, the more solar cells you use, the shorter the charging time.
FurReal Friends are furry animals that respond to your love and affection. The FurReal Friends can teach your child how to take care of pets. All pets need lots of attention and the FuReal Friends Newborn Baby Bird (Macaw Parrot) is no exception. Your child will have to feed and cuddle the baby bird to make sure it stays happy and content. The FurReal newborn parrot will squawk and flap its wings when it needs a drink.
FurReal Friends is a popular line of soft and cuddly, electronic animals that move and sound like the real thing. One interactive FurReal Friend is Butterscotch; an adorable pony that responds to your attention and care. This pony is over 3 feet tall and will respond to your interaction by blinking her eyes, moving her head and wiggling her ears. She can even move her tail, sniff your hand and whinny. Butterscotch is designed for children ages 4 and up and has a weight limit of 80 lbs. She even comes with her own adoption certificate, brush, halter and carrot.
Deep-cycle batteries are used to power golf carts, wheelchairs and other electrically operated items that need to have sustained power during discharge. This makes a deep cycle battery different from a regular car battery where amperes are most important as high power is needed to crank your engine during start up. Many factors are involved in comparing deep-cycle batteries such as cost, how you intend to use them, where they are fitted, power requirements and more. A systematic approach is best, to ensure you ultimately make the correct choice.
A marine deep-cycle battery comes in two different versions: a true deep-cycle battery with a few thick lead plates inside, which release energy slowly, and a hybrid combination that incorporates both a starting-type of battery, with many thin lead plates that provide a large surface area which releases a lot of energy quickly for starting, and a deep-cycle battery for accessory use. Both types of batteries would be considered a marine deep-cycle battery, meaning they can be discharged and nearly depleted, then recharged again without any damage to the battery cells inside. However, they are both made for specific purposes…
Nickel cadmium (NiCad or NiCd) battery packs are used to power many electrical devices, particularly cordless power tools. NiCad battery packs contain numerous individual cells that are wired together in a series to produce the voltage necessary to power your electrical device. Each NiCad cell produces 1.2 volts, but the milliamp hour rating (mAh) varies, depending on the type of cell. Test your NiCad battery pack to find out the voltage and mAh using a multimeter.
The capacity of a battery, including nickel-cadmium or NiCad batteries, relates to how much energy it can contain and is measured in milliamp hours (mAh). The length of time a battery lasts is known as endurance and is dependent on the device it powers. For example, a device that consumes 1 mAh from a 2 mAh battery means a fully charged battery will last two hours. Because every device a battery powers uses different electricity at different rates, batteries are labeled using an arbitrary mAh output suitable for the battery's designed purpose. Use a multimeter to accurately test your NiCad…
Getting a grip on basic electronics involves many topics, many of which are best learned through hands-on activities. These activities offer an understanding of the basic components and theories that compose everyday electronic items as well as those that are more complex.
The Fluke 87 III is the third model of the Fluke 87 series of multimeters. The most basic multimeter measures voltage, resistance and current. The Fluke 87 III also measures capacitance and frequency. Scientists use multimeters in laboratories and in the field. You can also use a multimeter at home to troubleshoot electronic equipment or test if a battery still has a charge.
The Canon PowerShot A640 is a digital camera with 10.0-megapixel resolution and a 4x optical zoom lens. It has 21 shooting modes and a 2.5-inch LCD display. The A640 can also shoot video with sound.
Electricity is the flow of electrons, and a battery is a device that causes electrons to flow. One simple kind of battery involves an acid and two dissimilar metals. You can make a lemon battery--if you hook things up correctly.
Being caught in an earthquake, particularly a strong one, is a frightening experience. If you live in or plan to visit an earthquake-prone area, taking time to familiarize yourself with emergency procedures can mean the difference between life and death.
NiCad batteries (also known as NiCd batteries) are batteries that use nickel and cadmium. People use these batteries in everything from remote-controlled airplanes to cell phones. If you're curious about whether the batteries are holding up to their advertised potential or if you just want to check if the NiCad battery you found in a drawer is still good, testing the battery will reveal how well it can operate. This will keep you from being stranded when you need the battery the most.
Hydrogen fuel can be made from water by an electrical process called hydrolysis. It is an electrochemical reaction in which the oxygen and hydrogen molecules in water (H2O) are separated. As gases, they bubble off of separate submerged electrodes attached to a direct-current electrical source.
The terms "marine" and "deep cycle" often give marketing information for batteries rather than specifications for use. A boat dealer would sell a marine battery for a pleasure boat for both starting a motor and operating extra equipment when the motor is not running. Technically, a deep cycle is an industrial battery used to power equipment, such as telephone switching offices in the event of a power failure. Some manufacturers have joined the names together to simply mean a battery that lasts longer.
The names "auto" (or automotive) and "marine" primarily give marketing information for batteries rather than specifications for use. Both cars and a speed boats need a battery to start, but the alternator provides the electricity while running. Some pleasure boats run more like RVs, cruising for a while, but often continuing to use electrical power when stopped. So, in some cases, automotive and marine batteries are interchangeable.
A dry cell is a form of electric battery and is one of the most common types of batteries used today. A typical dry cell is a simple flashlight battery. Dry cells consist of a metal container or can, usually made of zinc, that holds an acidic electrolyte paste of ammonium chloride and manganese dioxide, and a central core of carbon or metal. Most dry cells typically produce 1.5 volts.
Hasbro's FurReal Friends toys are mechanical plush animals that interact with their owners. Owners play with the animal by petting it or feeding it toy food. The pet responds by moving its body and making noises. Some FurReal Friends even respond to your voice or allow you to ride them.
