Buyers need to take many factors into consideration when purchasing a new camera. One of the most important elements is the battery pack, which dictates the number of pictures that you can take without recharging. The D80 Nikon camera, released in 2006, is the newer version of the two cameras; however, many aspects of the battery pack remain similar to the one in the previously released D70 Nikon camera.
A gum zapper is a device that squirts a chemical on gum that is stuck to carpet or another surface. The chemical dissolves the gum so the zapper can quickly and easily clean it up. A hand-held gum zapper runs off a battery that needs to be charged before you can use the device to clean up any gum. If your gum zapper needs charging it will come with all the necessary equipment.
Rotorway International was established in 1961 and is the largest and oldest manufacturer of helicopter kits. The Rotorway Exec 162F is a fully-featured helicopter that requires approximately 800 too 900 for an enthusiast to build.
A ceramic piezoelectric disk, which consists of a thin ceramic wafer glued to a slightly larger and thicker disk made of stainless steel, brass, or other metals, can conduct sound waves as well as electricity. It is used instead of a speaker or microphone for toys, alarms, smoke detectors, and other applications for which the quality of sound is not crucial. To use a piezo disk, you need to attach wire leads to it that are then connected to a source of sound or electricity. You do this by soldering the lead wires directly to the disk.

The X-Terminator Nitro Buggy is a remote-controlled model that is 1/8 the scale of a normal sized buggy and can be driven around your backyard or driveway. To operate your Nitro Buggy, you must turn the controller and then start up the vehicle's engine.
The common housefly is found all over the world. They are gray in color and are usually viewed at pests. They are found flying about in households, sewers, garbage heaps or any place they can find moist decaying matter. Houseflies prepare these places because they only feed on liquid foods. They can only feed on solid foods by regurgitating saliva onto the food first. The common housefly is also a major disease carrier. The University of Rhode Island reports they can transmit 65 different diseases to humans. Of all these things, however, the flight adaptations of the common housefly might…
NiCad batteries are often wired together to make a battery pack, as this increases the output voltage. The wired connections between the NiCad batteries needs to be good, otherwise the battery pack won't operate correctly and the best method is to weld tabs onto the battery terminals. You can use a professional spot welder to do this, but an easier and equally effective method is to use a soldering iron.

The Venom Night Ranger II is a radio-controlled helicopter developed by Venom Air Corps. Despite their small size, the moving parts on these toy helicopters are surprisingly complex and the slightest changes to the placement of the battery or position of trim sliders can drastically alter how well the toy flies. If you are having issues with your Venom Night Ranger II, a few adjustments can make the rig fly better.
In order to fly an R/C (radio-controlled) helicopter in the dark, it helps to light the blades powering the toy. Replace the blades of a series 400 R/C helicopter with the Venom night blades to illuminate it while flying. Venom night blades are available from the same hobby shop or store where the helicopter is available for purchase. A few tools standard for use on R/C helicopters will be needed.
Paintball is an amateur sport in which players compete, in teams or individually, to eliminate opponents by hitting them with paintballs fired from a device called a paintball marker, or paintball gun. The paintballs are typically made from non-toxic ingredients and are designed to release their colored content on impact, creating a paint splatter to show a target was hit. The Ion, a paintball marker made by Smart Parts, uses compressed air or CO2 to propel paintballs and can be set to multiple firing speeds.
Houseflies are common insects found all over the world. The housefly has the reputation of being both a pest and a carrier of disease. Disease organisms stick to their leg hairs before being transported unwillingly to new objects. Learning about houseflies is a matter of getting information from the experts in the field, whether it be online or in person.
Making your own buzz wire game combines basic electronics with a functional and entertaining game of skill using materials easily obtained from a hobby shop. The game uses a simple electric circuit with a buzzer, and is safely powered by a battery. It's easy to make, but hard to play without sounding the buzzer.
All electrical power sources have negative and positive poles. A readily available power source is a battery. If you look at the label on the battery you see a"+", usually on the top and the "-" usually on the bottom, meaning positive and negative, respectively. Interestingly, inside the battery, electrons move from the negative pole to the positive pole, but in a circuit the flow of current, measured in amperes, flow the opposite way; from the positive pole to the negative pole. The easiest method to tell the direction of a circuit is to use a multimeter.
The common housefly is viewed as a pest everywhere it goes. Although the housefly does not have the mouth parts to bite, it is still very troublesome. It shares some of the same characteristics of other insects, such as three main body parts and four stages of development. Unlike most other insects, however, the common housefly has more of a propensity for spreading diseases that can cause mild to moderate illness. In some underdeveloped countries, where they are more difficult to control, the housefly has caused numerous deaths from dysentery and other diseases.
Make a battery pack using several nickel cadmium (NiCad) batteries wired together in a series, for the purpose of increasing the output voltage. A regular NiCad only produces 1.2 volts, so the chances are whatever you need to power requires more than one NiCad. Soldering them together provides the best connection and, as they are rechargeable, you don't need to disconnect the batteries to charge them, so long as you get yourself a variable voltage rate NiCad battery charger.
The Nickel-Metal Hydride (NiMH) battery pack combines the energy of several individual cells into one energetic battery pack. You can combine any number of NiMH batteries together to enhance their overall capacity to meet the requirements of whatever you need to energize. Learn how to make a NiMH battery pack to prevent damage to the cells, and to get optimum performance from the finished pack.
Soldering forms a permanent bond between two metal objects using another alloy (metal). When building battery packs with several cells, the process of soldering can enable you to connect several of units together with minimal electronic resistance between them. Learn how to solder you NiCd cells to unite their individual capacities and render a durable, high-capacity battery pack.
The Schwinn Stealth 1000 is a motorized electric scooter that features a full-size frame with a 260-pound carrying capacity and a full-size deck. The Schwinn Stealth 1000 is powered by three 12-volt lead batteries that are contained in a sealed battery pack. The battery pack is then stored inside the seat compartment of the scooter. Replacing the batteries requires you to order a replacement battery pack from Schwinn prior to installation.
The scorpion fly is a member of the Panorpidae family and the Panorpa genus, which contains about 55 species north of Mexico and 240 species around the world, according to the Bug Guide. The insect gets its name because the male has a bulbous terminal appendage at the end of its tail that looks like a scorpion's stinger. However, scorpion flies do not sting.
Two major elements used in NiCd batteries include nickel, or Ni, and cadmium, or Cd. Most other types of rechargeable batteries use nickel, although the application of cadmium remains specific to NiCd units. Both elements have raised some environmental concerns regarding their production or disposal. Although manufacturers often use both of them to protect or mix with other metals, these elements have significantly different properties and histories.
Combining batteries enables you to boost the output voltage so you can power electrical items that need to operate on increased voltage. The method is called "Series" and combines the voltage produced from each individual battery. For example, if you combine four six-volt batteries in series, you get 24 volts. The method is often used in marine vessels and recreational vehicles where higher volts are needed, but it's equally useful to combine the voltage of smaller batteries to power items such as remote-control models.
Lithium polymer (LiPo) batteries are often combined into a battery pack to increase voltage. This is certainly the case if you're a remote control (RC) enthusiast and chances are you prefer to build your own battery pack to match the energy requirements of your RC model. It's important that the LiPo batteries are wired together securely, so using the right connectors is necessary. Soldering metal tabs to the LiPo battery terminals enables you to subsequently wire the batteries together in a professional manner.
Current draw refers to the amount of milliamps the electrical device that's connected to your battery is using. Knowing the current draw for your electrical device and the milliamp capacity of your battery when fully charged enables you to calculate how long the battery will last before you need to recharge or replace it.
Lithium polymer (LiPo) rechargeable batteries produce three times the voltage of nickel-based rechargeable batteries and weigh approximately 40 percent less. They also last longer. It is understandable why LiPo batteries are considered a good option for remote-control enthusiasts, particularly those that fly remote control helicopters and airplanes. However, LiPo batteries, especially those used in battery packs, do need to be charged correctly; overcharging can result in fire, and there are reports of the batteries exploding.
A rechargeable NiCd battery produces 1.2 volts and about 800 milliamp hours (mAh) when fully charged and in good condition. Milliamp hours relate to the time you can expect your battery to last based upon the milliamp consumption of the device it powers. For example, if your battery produces 800 mAh and the device it powers consumes 400 mAh your battery will last 2 hours. However, the charging and discharging process gradually reduces the battery's ability to maintain full mAh, so after a period of time you find that the NiCd battery goes dead quickly. You can test the condition…
A battery has a maximum amount of charge it can take when it's new. Over time, a battery's ability to retain a maximum charge starts to gradually decline. Although it becomes obvious your battery isn't retaining a full charge because the device it powers doesn't last as long, a more accurate method is to use a multimeter to measure the milliamp hours (mAh) and compare the result to the mAh labeled on the battery.
Battery-operated electrical devices are sometimes powered using a battery pack. Battery-pack manufacturers wire multiple cells in a series to produce the voltage needed to power a device. For example, a device that requires 18 volts to operate may contain five 3.6-volt lithium cells. If you have a device that requires higher voltage, but can't get a battery with the correct output, you will need to build a battery pack. A seven-cell battery pack is not so difficult to make once you understand some battery pack basics.
Nickel metal hydride (NiMH) batteries are rechargeable batteries which can be cycled, meaning recharged, up to 500 times. Most electrical devices need more than one NiMH battery to operate it as the output voltage from a single battery is only 1.2 volts. To ensure your batteries provide optimum performance, you need to maintain them as a group.
Battery banks are batteries wired together either using parallel or series wiring, depending on the purpose of the battery bank. The two wiring methods are similar but produce very different results. Parallel wiring enables you to get more endurance from your batteries while keeping the same voltage as one battery; two 12-volt batteries in a bank last double the time of one battery. Series wiring increases voltage; two 6-volt batteries produce 12 volts, but the batteries still last the same as one battery.
Linking batteries together can increase the power you get from them. Most electrical items use more than one battery to power them; you're used to inserting several batteries into your devices and this is because the voltage from most batteries is about 1.5 volts and your devices requires a higher voltage to operate. You can link as many batteries as you need to power your device, using a method called series wiring. It combines the voltage from the individual batteries so you get the voltage you need.
One of the most important aspects of your radio-controlled (RC) vehicle is its energy source. When it comes to the electric RC, the battery is everything. This key component is responsible for powering everything from the receiver to the motor, meaning that it is the beating heart of your car. Understanding the parts of your vehicle's battery will help you maintain the battery's life, while enabling you to identify malfunctions and make efficient repairs whenever things go wrong.
The Pro-164 is a hand-held police scanner capable of holding up to 1,000 different channels in its memory. Battery life can be problem if you use your scanner a lot, so while the Pro-164 operates using regular AA-sized alkaline batteries, it's best to use rechargeable batteries and to have a spare set ready charged. The Pro-164 has a battery charge indicator that indicates when you need to replace or recharge your batteries. However, if you want to tell more accurately if your batteries are charged, the easiest method is to test the batteries' milliamp hours (mAh) using a multimeter.
The lithium-ion, or Li-ion, battery is considered the new generation of rechargeable storage units, along with the lithium polymer, known as a Li-poly or LiPo battery. Typically a Li-ion cell produces 3.6 volts, so a six-cell battery produces 21.6 volts when fully charged. A Li-ion battery can be volatile; overcharging it is dangerous as the battery can catch fire, or worse, explode. Totally discharging one might render it unable to accept a recharge. Battery manufacturers, however, have built in safety devices for their batteries, preventing total discharge, whereas Li-ion battery chargers utilize an automatic cutoff system to avoid overcharging.
It's a sensible precaution to have a small store of nickel cadmium (NiCd) batteries. You never know when you may need to replace a dead one and NiCd batteries do start to lose their ability to retain power after a while. However, you need to ensure that when you need to replace a battery and use one you've stored, that it's still in good condition and ready to go, once it gets charged for a short while.
Lithium-based rechargeable batteries are available with two similar chemical compositions; lithium ion (Li-Ion) and lithium polymer (LiPo). They both produce between 3.6 and 3.7 volts, but Li-Ion batteries tend to be used to power items such as laptops and cell phones while LiPo is the preferred battery for remote control enthusiasts. It's imperative you use the correct charger to charge your lithium batteries as overcharging can cause them to catch fire, or even explode.
Portable rechargeable batteries are dry cell batteries with a chemical composition of either nickel or lithium. Many manufacturers of battery operated electrical devices increasingly choose to power them using lithium cells; they are lighter, produce higher voltage and last considerably longer than nickel batteries. Items that have benefited from lithium technology include laptops, cell phones and power tools. If you want to know how charged your rechargeable battery is, then the best device to use to measure it is a multimeter.
You can calculate exactly how many hours a battery will charge your keyboard, radio, camera or other device. Battery energy is a current measured in milliamp hours (mAh). Devices also have a mAh rating, which tell you how much mAh it draws from batteries it uses. With pen, paper and calculator, you can figure out how long it takes for that device to drain the mAh energy from its batteries.
Light emitting diodes (LEDs) are low-voltage, long-lasting lights that can be easily charged with a battery. This is a safe way to power LEDs because the battery is a low-voltage instrument. When attaching LEDs to a battery, ensure that the combined voltage of the LEDs is not exceeded by the battery's voltage, or the lights will blow out.
LiPo batteries, or lithium polymer batteries, offer an extremely efficient and lightweight method for storing electricity. They can store 300 percent more energy than comparable nickel cadmium batteries, and are 10 to 20 percent lighter. For these reasons, they are very popular for use in remote control helicopters and many other applications. However, LiPo batteries must be charged correctly to avoid catching on fire, emitting toxic smoke, exploding and otherwise losing the batteries. Knowing how to charge these batteries properly will keep you and the batteries safe.
Nickel-cadmium--or "nicad"--batteries are a type of rechargeable battery. This type of battery contains two electrodes made of dissimilar materials that are exposed to an electrolyte. The battery produces a voltage differential across the electrodes, and can be used to do work.
The energy source for your electric radio-controlled car is a key aspect of its overall performance. Nickel Metal Hydride (NiMH) batteries are a great source of durable, rechargeable battery cells, often utilized in the world of RC. It is important to know how to select the correct NiMH battery for your car to optimize performance, and minimize the risk of damage to the vehicle's components.
NiCad (Nickel Cadmium) batteries are a type of rechargeable battery used in many types of electronic devices. If the battery is not holding a charge you will need to rejuvenate or recondition the battery. These types of batteries store information that needs to be erased periodically to maintain the battery. To do this you need to first determine the nominal voltage of the battery for your device.
Batteries, large or small, produce electricity which is measured in voltage and milliamp hours. Voltage is the force and remains fairly constant until the battery is nearly discharged. Milliamp hours are the current and reduce as the battery discharges. Test your small batteries using a multimeter to determine if the battery is producing the correct voltage and how long you can expect it to last before you need to replace or recharge it.
A battery bank is multiple batteries wired together. If you have a device that needs to operate using a certain voltage, but don't have a battery with the correct output, wire two or more batteries together in series and you can power your device. For example, if your device operates on 10 volts then wire three lithium batteries in series and you get 10.8 volts; wiring in series adds the voltage from each battery together, but doesn't increase the endurance.
Lithium ion (Li-Ion) rechargeable AA-size batteries are about 40 percent lighter than regular alkaline non-rechargeable batteries and produce nearly three times the voltage; 3.6 volts compared to 1.5 volts. An additional benefit is they don't suffer from power loss like nickel-based batteries can, but Li-Ion batteries need to be recharged correctly using a lithium charger as incorrectly charging or over charging, can result in the battery getting damage and may be potentially dangerous. Replacing an AA-size Li-Ion rechargeable battery is no different to replacing a regular AA battery.
Remote control (RC) batteries are usually rechargeable batteries wired as a battery pack to provide greater voltage. They are often lithium-based batteries because they are lightweight and produce 3.6 volts compared to 1.2 volts from a nickel-based battery. Soldering an RC battery so it's wired to another battery to increase output is a fairly straightforward task.
Rechargeable cordless batteries are used to power items such as laptop computers, cell phones and cameras, to name just a few. As so many items use rechargeable batteries, it's likely you've experienced one of your batteries starting to go dead shortly after getting a full charge. Often the reaction is to dispose of it and get a replacement. Rechargeable batteries can be expensive, so before you spend your dollars, have a go at repairing your existing rechargeable battery, as certain types can easily be repaired.
A battery bank is effectively more than one battery wired in series or parallel. The number of batteries you need in your battery bank depends on either the voltage you require to operate your electrical equipment or the amount of time you want your batteries to last. For example, if your electrical equipment operates on 12 volts, wiring four 3-volt batteries in series produces 12 volts, or if you want to make a battery bank that lasts four times longer than one 12-volt battery, wire four 12-volt batteries in parallel.
The CR2032 battery is a lithium button cell battery that produces 3 volts when new. Button cell batteries are used to power devices that use very little energy such as watches or light emitting diodes (LEDs). A CR2032 battery generally lasts a long time, due to the low energy requirement of the device it powers, but if your watch is running slow, or your LED isn't bright, then use a multimeter to do a DIY test on your CR2032.
Nickel metal hydride batteries, or NiMH, are available producing various milliamp hours, or mAh. The mAh rating is used to determine the length of time a battery can last when it's fully charged. For example, if your NiMH battery has a rating of 2,000 mAh then it will power a device that consumes 1,000 mAh for two hours. Mixing different rated mAh NiMH batteries doesn't damage your electrical device, but don't expect it to operate as efficiently, or last as long, so it's best to only mix them as a temporary measure.
Dremel is the brand name of the most well-known maker of oscillating power tools. These handheld tools are designed to serve multiple purposes, changing their function based on what bits you fit them with. There are many dozens of different bits that you can fit on a Dremel, but they all fall into the same basic categories of tool work.
Regular AA batteries are nonrechargeable, alkaline-based batteries that power everyday items such as cameras, toys and flashlights. Electrical devices that use AA batteries generally have easy-access battery covers, except for children's toys in which the battery covers are held in place with screws for safety reasons.
Light-emitting diode flex lighting provides an impressive display of lights that are energy-efficient and long-lasting, but they can be expensive. If you want to get the effect of LED strip lights but don't want to pay store prices, then build your own. The light is fun to make and you will gain the pleasure of telling your friends and family members that you did it yourself.
A battery is an electrochemical device that produces direct current electrical power. A rechargeable battery is called a secondary-cell battery; non-rechargeable types are called primary cell batteries. Regardless of battery type, batteries use a controlled chemical reaction to produce electrical energy. However, the materials used differ depending upon how much energy is needed, and for how long a period of time.
Make yourself a DIY lithium polymer (LiPo) battery pack and you get a powerful, lightweight and durable battery that's great to operate remote control (RC) models. One LiPo battery cell produces 3.6 volts, that's three times more than a nickel-based battery cell. For example, if you've got an RC model that operates using about 10 or 11 volts, it needs nine nickel cells to operate it, or you could make your LiPo battery pack and only use three cells. You get a lighter RC model that goes faster and lasts longer, particularly useful if you're an RC airplane enthusiast.
Nickel cadmium (NiCd) batteries are used to power a wide range of cordless drills, although lithium-based batteries are beginning to replace them. Lithium batteries produce greater output and can power your device for longer, but the storage capability of lithium batteries is not as good as NiCd, according to Battery University. Temperature and the amount of charge in the battery during storage are important if you want to keep your NiCd battery in good condition.
A nickel metal hydride (NiMH) battery is a rechargeable battery that produces 1.2v output, the same as a nickel cadmium (NiCd) battery. However, many electrical items need a higher voltage to operate, so you must use a battery pack to power the device, and it can be expensive. A less expensive alternative is to make your own NiMH battery pack. Wire the NiMH batteries in series and make a battery pack that produces the voltage you need.
Remote control battery packs usually contain lithium polymer cells wired in series. Each LiPo cell produces about 3.6 volts, so four cells, wired in series, produce 14.4 volts. If you need to do an emergency charge but you don't have your charger, you can still charge your RC battery pack by connecting it to your car battery and turning on the engine. Your car battery produces 12 volts, so as long as the voltage from your battery pack exceeds 12 volts you can do an emergency charge on your battery.
Setting up many outdoor tents can be a hassle. But The Exxel Disney Princess tent is a piece of cake to set up. Since it uses only two poles and has no rain flap, the tent comes together nicely. It should be easy to do by yourself, or with the help of your child.
A voltage meter is a device for checking the charge in your batteries. It tells you the output voltage from the battery, which you then compare to the voltage output labeled on the side of the battery. This enables you to know when to replace the battery before it stops powering your device. The only problem is that a voltage meter can be expensive. However, if you want to check the voltage in your battery, there's an inexpensive method -- make your own DIY battery voltage meter using light emitting diodes (LEDs).
Mini T LED lights are made for radio-controlled vehicles. These small bulbed lights mount into the RC car's headlights and tail light fixtures and are powered by a 9-volt battery. The LED lights are designed to burn up to 10,000 hours, making them long lasting. Once installed, the lights shine bright allowing night time RC driving sessions. Because these lights are small, consider using tweezers to place them into position if you have large hands or fingers.
A Lithium-ion polymer (LiPo) charger restores power to rechargeable LiPo batteries. The unit is plugged into an electrical wall outlet via a power cord. The body of the LiPo charger has a pocket like the battery container of a battery-powered device. The LiPo batteries are slid into this pocket to be charged for a particular amount of time depending on the size of the battery. Aligning a LiPo charger refers to lining up the batteries within the charger. The process for aligning LiPo batteries in a charger is the same as aligning the batteries in the battery pocket of a…

Many radio-controlled (RC) vehicle enthusiasts consider the helicopter to be the single most difficult aircraft to navigate. But, the complex nature of the helicopter is what enables it to perform acrobatic stunts that are entirely impossible with other aircrafts. Therefore, learning how to properly fly your Rotorway Scorpion 2 will not only provide you with the skills necessary to pilot your aircraft with epic precision, it will also reduce any risk of damage to the vehicle.
BirDog manufactures satellite identification and alignment meters. The BirDog meter is powered by a 7.2 volt nickel cadmium (NiCd) rechargeable battery pack constructed using six 1.2 volt NiCd cells wired in series. Replacement BirDog batteries can cost about $50, but you can temporarily replace your battery pack with inexpensive regular alkaline AA batteries.
Universal serial bus (USB) battery packs power devices with an internal battery that routes electrical current through the power contacts in the USB plug. Making your own USB battery pack will take considerable time and effort, but it will save you money.
Getting your RC airplane off of the ground requires an engine. For a nonelectric RC airplane, you have the choice between one that uses gasoline and one that uses RC nitro fuel. Besides the differences between the types of fuel, the starting systems for the engines are also different: a gasoline engine needs an ignitor while the nitro engine has a glow plug.
The original PlayStation Portable (PSP) was launched in Japan in 2004, followed by the U.S. in 2005. Since then, several versions have been introduced to the market, including an optional extended-life battery kit. The regular PSP battery has endurance of between four and seven hours, depending on factors like screen brightness and volume. If you want your PSP to last longer between battery charges, make an external PSP battery pack wired in parallel.
The PSP, or PlayStation Portable, is a hand-held video game system developed by Sony and released in 2005. It contains multimedia capabilities and is compatible with many PlayStation 3 video games as well as having some Internet connectivity. The PSP can come in what is known as a "Pack" of different kinds, each of which contains a different combination of features, hardware and add-ons.
It doesn't matter what type of chemical composition your batteries contain, the result is the production of energy to power your device. What does matter is how much energy a battery produces in terms of voltage. Simply replacing three nickel cadmium (NiCd) batteries with three lithium-ion batteries will damage electrical equipment. An individual NiCd battery produces 1.2 volts while an individual lithium-ion battery produces 3.6 volts. For example, if your equipment operates on three NiCd batteries it needs 3.6 volts, the equivalent of only one lithium-ion battery.
Lithium-ion (Li-ion) batteries are rechargeable and are increasingly being used in many electrical appliances, replacing their forerunner, the nickel-based battery. The reason is simple: Li-ion batteries produce a nominal voltage of 3.7 volts compared to 1.2 volts from a nickel-based battery. Additionally, the milliamp hour (mAh) that can be drawn from a Li-ion battery is approximately three times the amount that can be drawn from a nickel-based battery. A Li-ion 18650 battery is the same size as a regular AA alkaline battery and generally has a nominal rating of 2,000 mAh. If you want to check that your Li-ion battery…
Remote control (RC) enthusiasts favor using lithium ion (Li-ion) batteries to power their units. One Li-ion cell produces three times the voltage and milliamps (mAh) of any nickel-based cells, so the battery pack is lighter, the remote control responds faster and it operates longer between charges. However, Li-ion batteries are expensive. If you have a 7.2-volt battery pack that won't work, you don't want to dispose of it unless absolutely necessary. Set aside an hour or so; you may be able to get the battery working again.
The Venom Night Ranger 2 RC helicopter is a ready-to-fly model that is rated for beginner and intermediate enthusiasts. The 300 gram helicopter has a charge time of about 2 hours. Because the Night Ranger 2 is a ready-to-fly kit, the simplest upgrade is to change the battery from the stock 8.4-volt, seven-cell 800mAh Nickel Metal Hydride (NiMh) to a Lithium Polymer (LiPo) battery. The LiPo is lighter and outperforms the NiMh in both power output and flight times.
There are hundreds of different home electronics projects. Many are doable at minimum cost with very little equipment. But how many are practical? It might be a lot of fun to build your own radio or tinker with the circuits in a toy keyboard, but those projects are just for entertainment. If you are pragmatic, you could try making some heated clothing. Heated socks are a good place to start, as they keep your extremities warm. The novelty is a plus, too: who do you know who owns heated socks?
Tenergy Corporation, based in California but with production facilities in China, manufactures a large range of rechargeable batteries and chargers for the worldwide market. The rechargeable batteries are available using nickel or lithium-based technology. A Tenergy 2600 battery refers to the milliamp hours (mAh) that a fully-charged battery can produce. For example, electrical equipment drawing 2,600 mAh discharges the battery in one hour; electrical equipment drawing 1,300 mAh discharges the battery in two hours. Test your Tenergy 2600 using a multimeter and you can determine if the battery is in good condition.
An electric buzzer is a simple device that creates sound by the rapid flapping of a diaphragm. Electromagnets propel this kind of buzzer by exposing a ferrous metal attached to the diaphragm to an oscillating magnetic field. The electromagnet pushes and pulls on the buzzer very quickly, causing the diaphragm to move up and down rapidly. They're relatively easy to make from an assemblage of household items. The only thing you may need to purchase is the electromagnet.
Radio controlled cars are a popular hobby for car enthusiasts. They do have many moving parts and like their real life counterparts, can develop faults. Cars that won't move forward may be suffering from a number of issues ranging from a broken engine, a drained battery or faulty gear casing.
Light emitting diode, or LED, micro lights use very little voltage and are excellent for use on Christmas trees or anywhere that needs attractive lighting, such as a patio area in the late evening. You can use a low-voltage transformer to power your LED lights, or alternatively attach the lights to a battery pack. You'll find they light up for days before the battery pack goes dead.
LR41 button cells are, as the name suggests, small, round, flat batteries similar in size to buttons you find on clothing; they are 5/16 of an inch in diameter, to be precise. LR41 button cell batteries produces 1.5 volts, but only retain a small amount of energy, so they are used to power items that draw very little power, such as LED displays and watches. If you have an items that uses a small amount of amount of electrical energy, but requires more than 1.5 volts, arrange your LR41 button cell batteries in series and you can increase the voltage.…
Lithium polymer (LiPo) batteries are the battery of choice for remote control enthusiasts. LiPo batteries are slim, lightweight and produce three times the voltage of nickel-based batteries. However, LiPo batteries are expensive compared to nickel-based batteries, so you need to ensure they are charged using the manufacturer's instructions, as this prolongs the battery life. What's more, checking that your LiPo battery is correctly charged ensures you keep your battery in good condition. Determining the LiPo battery charge is best achieved using a digital multimeter to measure the voltage and milliampere hours.
Battery packs contain individual cells wired together internally to increase electrical output. During normal use, and if a battery pack is in good condition, the cells in the battery pack discharge at the same rate, so when a battery goes dead all the cells are discharged. However, when the battery pack starts to age and has been charged and discharged many times, it's possible that the individual cells become unbalanced. This means the charging and discharging rate in each cell is different, due to chemical changes and the battery doesn't last long between charges. If this problem occurs, balance the…
Lithium ion (Li-ion) and nickel-metal hydride (NiMH) batteries are popular rechargeable batteries. Although used in similar applications such as cameras and laptops, they have different chemistry and characteristics.
If your actions in your favorite XBox game aren't fast enough for your liking, adding a boost switch to your controller can give you that extra bit of speed. A boost or rapid fire switch sends a signal to the controller, which the controller interprets as super fast user input. Completing this mod will require you to be able to solder, and it helps if you have prior experience in working with motherboards. You'll also have to purchase a push-button switch from a hardware or electronic supply store.

If you have difficulties finding a suitable way to charge your TomTom battery, then make yourself a LiPo battery…
Nintendo DS is a hand-held gaming system produced by Nintendo. Perfect for playing video games on the go, it has become an extremely popular gaming device. Disassembly is fairly easy and can be done with minimal assistance.
A nebulizer is a piece of medical equipment used to administer medicine that is formed into a vapor or fine mist and taken into the body by the use of a mouthpiece or face mask. A nebulizer is used to administer medicine to those people with respiratory ailments such as asthma. Many nebulizers on the market are battery run, so it is important to make sure the battery is charged and ready for use at all times, especially for chronically ill patients.
Keeping a regular maintenance schedule will ensure any tool will function at its peak performance. The Milwaukee right angle drill is built to be durable and sturdy but it is no exception. Cleaning the drill after every use and storing it in its carrying case is a good maintenance practice. The proper way of cleaning the drill is also important. The manufacturer of the drill recommends using a mild soap in cleaning the drill because other cleaning agents and solvents can damage the plastic and insulated parts of the drill.
If you're a remote control (RC) enthusiast, you need to power your RC model using rechargeable batteries. Rechargeable batteries are more expensive, but you ultimately save money because they can be recharged up to 200 times before they must be replaced. An additional benefit of using rechargeable batteries is they can produce more voltage and are lighter, depending on the type of rechargeable batteries you choose. Making your own rechargeable battery pack to power your RC model is moderately easy.
Make your own battery pack for your remote control model (RC). It's less expensive than purchasing a factory-made one and is more rewarding. You can use any rechargeable batteries, but if weight is important, for example if you fly RC airplanes, then use lithium polymer (LiPo) batteries. LiPo batteries produce 3.6 volts whereas nickel-based batteries produce 1.2 volts, meaning you only need to use one LiPo battery for every three nickel-based battery. This makes your battery pack two-thirds lighter.
Lithium polymer (LiPo) battery cells are increasingly popular and are used extensively in remote control models, particularly airplanes. LiPo cells produce 3.7 volts and have a capacity of 2,100 mAh (milliamp hours), if in good condition, which is approximately three times more than a nickel-based rechargeable battery. If you want to test the condition of your LiPo battery pack then use a multimeter and you can test the voltage and mAh.
Most cell phone batteries produce 3.7 volts and are lithium-based. It's likely your remote control (RC) airplane needs higher voltage to operate, so you may need to wire a couple of cell phone batteries in series to get to the correct voltage. The advantage of using cell phone batteries is that they are light in weight, which is an important factor when you fly RC airplanes.
If your RC car is getting too hot, you may wish to put a home-made cooling fan inside it. This fan can be made cheaply with some readily available components. Keep in mind that this device will add weight to your RC car, possibly slowing it down, but cooler components have longer operational lives.
Lithium polymer, or LiPo, batteries are responsible for major advances in battery pack design and usage. LiPo batteries produce 3.6 volts; three times the voltage of nickel cadmium and nickel metal hydride batteries. This means you need a lot fewer batteries in your pack to produce the voltage you need to power your device. Importantly, fewer batteries means less weight, which makes a LiPo battery pack an excellent choice for remote control airplane enthusiasts.
Rechargeable batteries are used by many remote control (RC) enthusiasts to make battery packs to power their models. It's important to ensure that the batteries in the pack are connected properly, as poor connections mean your pack won't produce the correct amount of energy. The best way to make certain you have excellent connections between the batteries is to weld tabs on the batteries using metal strips and a soldering iron.
Remote control, or RC, enthusiasts often use nickel metal hydride, or NiMH, battery packs to power their RC models. NiMH batteries are considered better than nickel cadmium batteries, or NiCAD, as they don't suffer from "memory effect," which is when you charge your battery fully and find it only lasts a short time before going dead. Factory-made NiMH battery packs can be expensive, so make your own battery pack if you want to save money.
Lithium-ion or Li-ion batteries produce higher voltage than other rechargeable batteries such as nickel-cadmium or nickel-metal hydride: One Li-ion battery produces between 3.6 and 3.7 volts, compared to 1.2 volts for the other two. If you need even more voltage to power your device, linking Li-ion batteries together into a pack is a good choice. Two Li-ion batteries wired in series will produce 7.4 volts.
Putting lights on your remote control (RC) airplane is a great way to add a more realistic look as well as to find it during dark nights. Thankfully light emitting diodes (LED) make this endeavor relatively simple with just some simple soldering. You can even select the color of the LED light that you want so you can replicate the traffic lights on real airplanes. As a bonus, LED light draw very little power so you will not compromise your RC airplanes operating range.
Nickel cadmium (NiCad) batteries are used as replacements for alkaline AA batteries because they are rechargeable and produce similar milliamp hours (mAh) despite producing 1.2 volts compared to AA alkaline batteries' 1.5 volts. If you find the device powered by your NiCad 1.2-volt, 700mAh battery doesn't operate, then you may recharge the battery.
Nickel cadmium (NiCad) batteries are used to power an immense number of devices from cameras to power tools. Individual NiCad cells are sealed units and contain dangerous chemicals, so never break them open. However, a NiCad battery pack can be rebuilt moderately easily if you find the pack goes dead quickly. It only takes one cell in the battery pack to go bad to affect how much energy the pack can produce and how long the battery lasts.
Making a DIY external battery pack is a great way to ensure that you've got an extra power supply, if your internal battery goes dead. Digital cameras are a typical example of how inconvenient and annoying it can be when the battery dies --- it always happens just as you're about to take a once-in-a-lifetime picture. Make a DIY battery pack, and you never need to worry again.
Radio control vehicles are one of many popular American hobbies. Enthusiasts usually like to build and wire RC vehicles themselves as well as tweak and play around with the capabilities of the vehicles as well as the looks. One of the basic things that an RC enthusiast should be able to do is wire the RC battery to the radio receiver, motor and electronic speed control (ESC) mechanisms. This is also one of the simplest of projects in the RC world.
If you wire batteries in series you can adjust the output voltage from the batteries to voltage you want. Wiring batteries in series adds the output voltage from each battery, so, for example, if you wire four 6 volt batteries in series you get 24 volts. There's really no limit to the voltage you can make if you wire batteries in series, but this article focuses on wiring eight 6 volt batteries in series to produce an output of 48 volts.
Megatech develops radio controlled boats, airplanes, dragsters, helicopters and more in three series: IQ, Big Fun and High Performance. Your Megatech Housefly 2 helicopter falls under the High Performance series, which features the latest advanced technology. After assembling your Housefly 2, you will need to learn the basics on how to fly it and land, so you can develop flight maneuvers. Troubleshooting your Megatech Housefly 2 can help you learn more about your helicopter and allow you to resume your flying enjoyment more quickly.
RC (radio-controlled) race cars featuring gas-powered propulsion, known as RC Nitro cars, can travel substantially faster than their electric-powered alternatives. With this extra power, RC Nitro cars are capable of delivering the extra torque required to power through the snow if the owner desires. Before taking your car out when the temperatures have dipped, it is important to winterize the vehicle to prevent against damage that the cold temperature can bring, even when no snow has fallen.
Factory-produced nickel cadmium (NiCd) battery packs can be expensive. Building your own is a less expensive option and does the job just fine. NiCd cells produce 1.2 volts, so an important first step is to find out how many cells you require to power your device. The voltage your device needs is on the label attached to the device. Note the figure, then divide it by 1.2 and round the answer down to the nearest whole number. For example, if your device needs 7.2 volts, divide it by 1.2 to get 6.25, then round down to 6.
Constructing a DIY battery pack means you can wire as many batteries in series as are needed to power your device. Wiring in series combines the output voltage from each battery, so if you wire four 1.2 volt batteries in series you construct a 4.8 volt battery pack. Nickel cadmium (NiCad) and nickel metal hydride (NiMH) are the most popular batteries, as they are rechargeable. Here we construct a battery pack using four batteries, but you can use any number. Just divide the voltage of your device by 1.2 to determine the number of batteries required.
Lithium battery cells are increasingly used to power cordless tools and are popular with remote control, or RC, enthusiasts. They are light, durable and produce three times the voltage of nickel cadmium and nickel metal hydride cells. They are also environmentally friendly and can be disposed of in regular trash: something you can't do using nickel cadmium and nickel metal hydride cells. Two types of lithium cells are manufactured: lithium ion, or Li-ion, and lithium polymer, or LiPo. They're similar in size, function and output, except Li-ion battery packs need to have power surge circuits built in to stop overcharging…
Craftsman is the brand name for a comprehensive range of manual work equipment, including a line of battery-operated power tools. The more powerful cordless tools operate use a 19.2-volt battery pack. Recent Craftsman battery packs contain nickel metal hydride (NiMH) cells, which are increasingly replacing nickel cadmium (NiCad), as they are more durable and not as susceptible to the commonly used term "memory effect." This is when a battery appears fully charged, but may only be halfway charged. It occurs if a battery is not fully discharged on a regular basis. If this happens, there's a simple procedure to restore…
Piezoelectric buzzers are used as cheap, dependable devices to generate an alarm tone in electronic circuits. A piezo buzzer consists of a piezoelectric disk wired to an oscillator. When electricity flows across the piezo electric disk, the disk bends. The oscillator sends an alternating electric signal across the piezo disk, causing it to bend first one way and then the other. This rapid bending back and forth pushes air, making a loud tone come out of the buzzer. Because piezo buzzers include oscillators, all you need to do to power one is attach it to a DC current source.
Battery pack connectors appear in a variety of electronic toys, games, GPS units, and other devices. These connecting plugs are designed to connect the device to the battery pack power source in order to power up the unit. Battery pack connectors come in various shapes and colors but all share identifying characteristics.
Remote control, or RC, models such as cars and airplanes use rechargeable battery packs to power them. Until recently, RC battery packs consisted of multiple nickel cadmium (NiCad) or nickel metal hydride (NiMH) cells, but many RC enthusiasts are upgrading their battery packs to lithium polymer (LiPo) cells. LiPo cells have greater capacity and produce 3.7 volts --- three times the output from NiCad or NiMH cells. This means RC models operate using fewer cells and less weight. Lowering the weight results in RC model cars going faster, but using less energy. It's particularly beneficial in an RC airplane because…
Electric scooters are small vehicles using two or three wheels powered by an electric motor, which permit people to travel economically for short distances. Not only are they considered green and eco-friendly, but they also serve to make a statement for the average young mobility seeker. Electric scooters are innovative means of transport and are quickly becoming popular in urban, densely populated cities.
Lithium polymer (LiPo) batteries are durable and light, and each LiPo cell produces 3.7 volts, compared to 1.2 volts for NiCad or NiMH battery cells. These attributes mean LiPo batteries are the battery of choice for remote-control enthusiasts. A three-cell LiPo battery produces 11.1 volts, perfect for model airplanes and many notebooks. To connect your battery to your device, you need to wire a charge plug, which is available at electrical parts stores for a few dollars. Just be sure that you buy a charge plug that is compatible with the charge socket on your device.
The Megatech P-51 is modeled after the North American P-51 Mustang fighter plane deployed in World War II. Suitable for ages 12 and older, the P-51D Mustang RTF is a remote-controlled airplane manufactured by Megatech, which is based in North Bergen, N.J. The Megatech P-51 Mustang part number is MTC 9936, and its assembly kit includes a three-channel radio transmitter, a NiMh (nickel-metal hydride) rechargeable battery pack and a DC peak-detection quick charger.
Button cell batteries are small flat objects used in appliances such as clock radios. They keep the time display and other preset information operating if the electrical power fails. They also are used in calculators and watches. Button battery cells produce between 1.5 and 3 volts, depending on the chemical composition such as alkaline or lithium. Button cell batteries are perfect for powering devices that use little energy. If you have a device that requires increased voltage to operate, but uses little energy, then making a custom battery pack would be ideal.
Rechargeable battery packs make using power tools much easier. You can use your tool anywhere and never have to worry about wires and plug sockets. Tool battery packs only last a certain time before they need replacing. The more you charge and discharge your battery, particularly NiCad batteries, the sooner its needs replacing. Replacement battery packs can cost 1/3 or more of the price a new tool costs, so the cost-effective way is to rebuild your existing battery pack.
Battery power packs for drills and other types of tools are made using individual battery cells that are wired in a series. If you wire battery cells in a series, you combine the output voltage from each cell to create increased voltage. Four 1.2 volt NiCad battery cells wired in a series produce 4.8 volts. A problem, though, is that not all battery cells go dead at the same time and this is particularly the case with NiCad cells. This means that while the battery for your drill keeps running out of charge quickly, it may only be one or…
NiCad battery packs are made from individual cells: the number of cells depends on the output voltage of the battery pack. Each NiCad cell produces 1.2 volts, if it's in good condition and fully charged. NiCad battery packs are popular, but after a while they can lose their energy quickly. The problem is, if you find your battery pack goes dead after very little use, it may not be the entire pack: it may be one or two cells. It's better to fix your NiCad battery pack using replacement individual cells than having the expense of buying a new pack.
Cordless battery packs are made up of individual cells wired in series. Wiring in series combines the voltage from each cell so if your battery pack contains four NiCad or NiMH cells, the output voltage is 1.2 volts multiplied by 4 to produce 4.8 volts. Battery cells don't all die at the same time. If your cordless battery pack is dying too quickly, it's cheaper to replace the bad cells rather than the entire battery pack.
Lithium polymer (LiPo) batteries are the battery of choice for many remote control enthusiasts. They are lighter than other rechargeable batteries and their output is greater: 3.7 volts per cell compared to 1.2 volts per cell for NiCad and NiMH batteries. Battery packs are made from individual cells, wired in series. Wiring in series combines the voltage from each cell and while the capacity remains the same as for one cell, the voltage increases. For example, a five cell LiPo battery produces 18.5 volts, but five Nicad batteries only produce 6 volts. However, individual cells can go bad, affecting the…
Nickel metal hydride (NiMH) batteries are rechargeable and have 50 percent more capacity than nickel cadmium (NiCad) batteries and two or three times the capacity of alkaline batteries. Each battery produces 1.2 volts when fully charged. To build a 7.2-volt NiMH battery pack, you need to wire six batteries in series. Wiring in series combines the voltage from each battery but maintains the same capacity.
Battery packs are made up of individual cells that are usually rechargeable. They can be wired in a series to provide increased output while maintaining the same capacity, or wired in parallel to increase capacity and maintain the same output. Battery packs are commonly used by remote control vehicle enthusiasts to power their model cars or airplanes. The output voltage of battery packs vary depending on the number and type of batteries used. Over time, battery cells deteriorate, but they don't all do it at the same time, and therefore it's cheaper to replace the damaged cells than replace the…
You can easily build rechargeable battery packs using batteries such as Lithium Polymer (LiPo), Nickel Cadmium (NiCad) or Nickel Metal Hydride (NiMH). There are two methods, series and parallel. Wiring in series combines the voltage of each battery in the pack while the capacity remains the same. Wiring in parallel maintains the same output voltage as one battery, but the capacity increases. This article tells you how to build a four-cell battery pack, but you can use as many batteries as required.
Rechargeable batteries are more expensive to purchase, but they save you money over time. This is particularly true if you need a battery pack to regularly power equipment such as remote controlled (RC) cars or airplanes. Batteries such as nickel cadmium (NiCad) or nickel metal hydride (NiMH) are popular choices for RC car enthusiasts, while lithium polymer (LiPo) batteries are chosen by RC airplane enthusiasts, due to the that battery's lighter weight and higher output voltage. Build a rechargeable battery pack wired in series to increase output voltage: RC models need about 10-volts to operate, although it varies by type.…
If you're looking to add a few minutes to your RC car's run time, or get more bang for your buck, consider changing the power source. Battery packs vary in their shape, capacity and chemical makeup. All of these aspects are important things to consider when deciding which will optimize your vehicle's performance.
Nickel metal hydride (NiMH) batteries offer special charging challenges over other rechargeable batteries. Overcharging a NiMH battery will cause the battery or battery pack to overheat and shorten the life of the battery. Using a battery charger designed to charge NiMH batteries will ensure the battery is not overcharged. These types of battery charges utilize a full charge limit switch that turns off the charger before the battery overcharges and in turn reduces overheating.
LiPo stands for Lithium Polymer batteries, which were originally developed for use in cell phones and laptops. However their light weight and durability has extended their use to RC (remote control ) enthusiasts, particularly those who fly model airplanes. LiPo batteries have an average output of 3.7-volts; model airplanes usually require more than one cell. Building a LiPo RC battery pack in series enables you to increase voltage based on the number of batteries you have in the battery pack. For example two LiPo batteries, wired in series, have an average output of 7.4-volts while four produces 14.8-volts. Wiring in…
Li-Po batteries, or Lithium polymer battery packs, are used in RC cars and airplanes. Li-Po batteries are also called Li-Poly battery packs. They can come in single or multi-cell designs. A single cell (1S) has a voltage of 3.7, and battery packs can consist of two cells (2S), three cells (3S) or more. Any Li-Po battery pack needs to have its charge balanced on a regular basis. Balancing the battery pack allows each battery cell to match the voltage of the other, which prevents irregular flows in current and provides optimum performance in the electrical device.

These engines generate immense power (sometimes up to 3 horsepower) and run at high revolutions, often exceeding 30,000 rpms. Nitro engines come in a wide variety of shapes and sizes and are made by numerous manufacturers. The basic procedure to start them up, however, is the same regardless of model and size.
The Nintendo Wii console uses wireless remotes that contain both a motion sensor and an infrared sensor. Being wireless they require their own power supply. Be default, the Wii remotes utilize either rechargable or disposable standard AA batteries. However, third-party companies such as Dream Gear create battery packs that replace these batteries and eliminate the need to keep changing out AA batteries. The battery packs snap right onto the back of the Wii remote and require no special skills or tools to install.
Rechargeable battery packs have only recently become a standard in the video game industry. Since the 1980s, the video game world has seen many improvements to the controller in an attempt to increase comfort, functionality, and usability. In 2005, Microsoft released the Xbox 360 and set a new standard by including wireless controllers with rechargeable battery packs. However, with repeated use, these battery packs lose their charge. Rather than purchase an entirely new battery pack, there is a way to replace the batteries instead.
The DreamGear battery pack connects to the back of a Wii remote, thus eliminating the need for AA batteries. The included DreamGear charging station allows you to charge the batteries without having to remove them from the remote.
Many modern electronic appliances use cords equipped with FireWire plugs for charging purposes. These plugs also allow the device to connect to computers and laptops for data transfer. One of the disadvantages of this setup is that users must find a computer or power outlet to charge their device. However, some clever individuals discovered a way to charge their FireWire-equipped devices with batteries stored in common Altoids tins. This improvisational charging station is convenient and, most importantly, portable.
The Xbox 360 comes with a number of useful features, including dual analog thumbsticks, and left and right triggers used for easy firing. One feature that it does not come with is a turbo or rapid fire boost. Even though the controller lacks this feature, it is possible to modify it so that it becomes a turbo controller. This process will require some disassembly of your 360 controller, but you'll find that the process is relatively straightforward.
Lithium polymer (lipo) battery packs store much more energy than their counterparts. These battery packs are also lighter and retain a charge longer. Lipo battery packs do not develop "memory," and therefore do not need to be fully discharged before the next charge. A combination of lipo cells forms a battery pack. Adding cells in a series increases the voltage of the pack, whereas adding cells in parallel increases its capacity. Observe specific instructions when using lipo packs in order to avoid dangerous situations.
Lipo (lithium polymer) batteries combine a high discharge rate along with a high energy-storage-to-weight ratio. The combination leads to an ability to provide a greater flow of energy over a longer period of time for its weight than most other battery types. Because of this, lipo batteries are the battery of choice for remote control modelers looking to power their vehicles with an eye towards speed and stamina. The high efficiency of lipo batteries comes at the price of high maintenance. Lipo batteries are relatively fragile. If handled improperly they damage quickly. Damages can range from minor, such as no…

Building your own radio-controlled (RC) car battery pack can provide with longer run times and better performance during a race or running your vehicle at home. Making your own battery packs also ensures the connections between the cells are more secure, with less electrical resistance than typical factory-assembled packs. Most electric RC vehicles utilize six 1.2-volt "sub-c" battery cells wired in series to gain a maximum of 7.2 volts. Check with your RC vehicle's documentation to determine the its voltage limitations before building your battery pack. (ref#1)
Many electric radio-controlled cars use 7.2 volt battery packs as a source of power. These battery packs, when purchased new, have a small charge already in them, which keeps them from going dead while on the shelf. New batteries have two steps to charging them. You need to discharge them slightly to remove the pre-charge and then charge them fully before use. Once the battery is charged, use it to power the RC car.
The rechargeable battery packs that are used to power many of today's electric devices are composed of a group of individual rechargeable cells. Before the development of the coin cell, named because it is similar in size to a coin, battery packs were usually relatively large. This is because the packs were limited to using conventional AA, AAA or C size batteries. Using coin cells, you can make a much more compact battery pack, which can be designed specifically for your custom application.
Batteries are used to provide direct current electrical power. These devices can be constructed from a number of materials; however, the most common batteries contain either an alkaline or acidic electrolyte between at least two parallel metal electrodes. Each one of these electrode pairs is called a "cell." Batteries can be made of one cell or several cells linked together. A similar concept is used when designing battery packs.
Dremel tools have become very popular because of the wide variety of jobs for which they can be used. The owners of these tools often use them so frequently that the rechargeable batteries that power them will decline in performance or fail long before the tool itself. When this happens, it sometimes makes more economic sense to rebuild the battery pack rather than buy a new one.
The battery packs that power small electronic devices are usually comprised of a number of rechargeable coin cells stacked together so that they are connected in series. These battery packs can be expensive to replace if you purchase one from the manufacturer. Building your own coin cell battery pack is something anyone can handle, and you are likely to save a lot of money in the process.
Many of the devices that are in use today are powered by rechargeable battery packs. Although these battery packs are rechargeable, if they are put into heavy use and undergo one or more charge and discharge, they will eventually begin to fail. Replacing a battery pack can sometimes be prohibitively expensive, especially when you consider it versus the cost of replacing the entire device. In this situation, you may consider making a homemade battery pack. This process can also be used to create battery packs for custom applications.

Many devices use alkaline batteries for electrical power. Some devices use standard 9V batteries. However, other devices require a 9V DC power source, but use a combination of AA, C, or D cells to add up to 9V. Larger batteries, such as C and D cells, may be preferred for high-current or long-lasting devices, such as boom-boxes or flashlights. Other devices, such as personal radios, may require the batteries to be inserted in as flat a space as possible, thus requiring slim-profile AA or AAA batteries. Whatever the battery configuration, the result is the same--several individual cells are used to…
Electric-powered RC vehicles are very popular since they are quiet and easier to maintain than gas or nitro powered vehicles. Electric vehicles use high-tech, rechargeable batteries for their power. These battery packs come in different shapes and sizes and use a variety of battery chemistry. Sometimes it is easier and more cost effective to build your own battery pack than to buy a pack that is preassembled. There are a few things to consider when assembling a homemade RC battery pack.
Nickel and cadmium, nickel cadmium, NiCd, NiCad. All of these names describe one type of battery on the market today. These batteries, like any other rechargeable type of battery, need to be recharged every time you notice a decrease in performance. This means the charge capacity is low, and it needs to be refreshed. Rechargeable NiCd batteries are eco-friendly because not only do you get a lot of use from each battery, but you can also recycle these batteries in various locations throughout the world. Popular places to recycle batteries are Best Buy, Radio Shack and Walmart.
Keeping the battery charged on your digital camera ensures that you won't miss that once-in-a-lifetime grab shot.

Building a solar collector for space heating can illustrate how solar energy functions. A solar air heater consists of a Plexiglas-covered box containing baffles and black-painted sheet metal with a heat exhaust hole cut at the top and a cool air intake hole cut at the bottom. The black sheet metal absorbs the sun's heat and causes the air inside the box to warm up. As the air becomes hotter, it passes through the baffles and is blown out as hot air by a fan over the exhaust hole.
RC trucks are a fun way to enjoy the afternoon racing or off-roading in a dirt field. A battery pack for a n RC consists of six to seven 1.2 volt Nickel Metal Hydride (NiMh) sub c rechargeable batteries. They are connected in series to make a 7.2 or 8.4 volts capable of operating most electric RC trucks on the market. Building a battery pack can be better since you choose the type of components to put into it.
Flying an R/C helicopter can be a daunting task when first learning. The combination of controlling the height, direction and tilt to get your helicopter from point A to point B can be confusing.

It's also helpful to approach flying your R/C helicopter in a step-by-step process, starting with simple control orientation before moving on to the high-flying acrobatics you'll be using after a little practice.
Bosch variable speed drills can double as a power screw gun by using a screwdriver bit. This lets you buy one tool and use it for two purposes. Bosch impact drills now are supplied with lithium-ion batteries, which allow for minimum self discharge and no memory effect. That means you can put the screwdriver bit and a battery in your drill, leave the drill for a period, and when you come back to it, you're ready to drive a screw.

It can be frustrating to own a cordless tool with a battery pack that no longer provides enough power or won't charge properly. The thought of spending the money to buy a new battery pack or even a new tool if the packs are no longer available is not very appealing either. The good news is that battery packs are made up of simple rechargeable cells, and if you are willing to invest the time and effort you can rebuild one yourself.
Most cordless tools will outlive the battery packs that come with them. It would seem like the simple solution would be to buy a new replacement pack, but often these packs can be difficult to locate, sometimes the manufacturer has discontinued making them or they are just too expensive in relation to the tool to justify purchasing them. Because most cordless tools use battery packs that consist of a group of size sub-C rechargeable batteries, you can rebuild the pack yourself.
It can be frustrating to have a cordless screwdriver, cordless electric drill, or other tool with a battery pack that no longer works. If you cannot locate a replacement pack for purchase or find that they are too expensive, you may want to rebuild the pack yourself.
As its name implies, the HPI Wheely King is designed to pop wheelies on demand. But with its beefy straight axles, multilink suspension and dual vertical plate chassis, the Wheely King can become a great rock-crawling rig with just a few modifications. The truck gets its wheely-popping prowess from its reward-mounted motor and a battery pack that places the weight of these components on its tail end to allow it to easily pop wheelies. The steps below show you how to relocate the motor and battery pack to the front of the truck for improved rock-crawling weight distribution.
