Powermat - How Does the Powermat Wireless Charger Work?

PowerMat is an exciting new wireless charging technology. It was first demonstrated in 2008 and early 2009 and is now available to buy for the home and office.

Powermat - How Does the Powermat Wireless Charger Work?

So what is PowerMat? It is a small device that uses wireless charging to charge your most important gadgets like cellphones (including the iPhone and Blackberry), video games (including the Nintendo DS), and iPod without you having to connect them to a charger or plug them into the wall. The PowerMat itself is, of course, plugged into the wall and connected to mains electricity by a wire, but from then on everything is wireless. You drop your device onto the PowerMat and it gets charged wirelessly, without you having to do anything.

The technology behind PowerMat is known as 'electromagnetic induction' (or just 'magnetic induction'). Michael Faraday is generally credited with the discovery of the induction phenomenon in 1831 though others were working in the same field at the time.

This electromagnetic induction is officially defined as "the production of voltage across a conductor situated in a changing magnetic field or a conductor moving through a stationary magnetic field" but that does not mean very much to most people. A better way to put it is that it is a means to transfer electrical power using a shared magnetic field.

Consider this arrangement:

1. Put electrical power into a coil of wire

2. This will produce a magnetic field around the coil that affects any metal within the field (as demonstrated by Faraday)

3. Change the field quickly over time and an electric current will be generated in the metal

So what is happening when a PowerMat is charging is that it is generating rapidly changing magnetic fields above the mat; these are converted by receivers on any devices on the mat into electrical power, and so these devices get charged. The magnetic fields and electrical currents are, of course, very small and so they can work on handheld gadgets without being a health risk to humans.

The same technology is used in a huge number of other devices and systems including generators, motors, transformers, some cookers, induction welding, and so on. Perhaps to most people the best known example is in rechargeable electric toothbrushes, where they are familiar with dropping a toothbrush into a 'dock' daily to keep it charged. However they may be unaware that similar systems are also operating in electric guitar pickups, video tape players, and computer graphics tablets.

PowerMat is currently the best known example of a wireless charger but this technology is developing rapidly and soon we will see it in many other applications and products. The PowerMat company itself is planning to extend the technology and feature it in kitchen counters, walls, and other surfaces around the home. One day this technology may be used everywhere and be invisible, it will be so commonplace. Finally we will be freed of the endless tangle of chargers and wires around the home.

Golf Cart Battery Basics

Golf cart batteries are the life-force behind your electric golf cart.

Golf Cart Battery Basics

Golf carts run off of what are called deep-cycle batteries. Although they look similar to normal car batteries, deep-cycle batteries serve a completely different purpose. While both are lead-acid based, deep-cycle batteries provide a steady current over a long period of time, whereas car batteries provide a very large current over a short period of time. This is because golf carts, like other electric vehicles, derive all their power from their batteries.

One battery is not enough to run a golf cart. Instead, they use battery packs that consist of multiple batteries. Individual golf cart batteries usually come in 6-volts or 8-volts. The combined total of the voltage from each battery makes up the total golf cart voltage. For instance, a 36-volt golf cart probably has six 6-volt batteries. And a 48-volt golf cart probably has either eight 6-volt batteries or six 8-volt batteries. And as you can probably guess, the higher the voltage the longer the run time and the greater the power.

If your batteries aren't charged, however, it doesn't matter how many volts your battery pack has, it's still not going to run. The type of golf cart charger you would need depends on the total number of volts your battery pack has. A 36V golf cart requires a 36 volt charger, and a 48V golf cart requires a 48 volt charger. If you have a 36V golf cart and later decide to upgrade to a 48V golf cart by adding two additional 6V batteries, you can either purchase an additional 12V charger for two new batteries, or you can replace your 36V charger with a 48V charger, just so long as the voltage from the charger corresponds with the voltage of the batteries.

To keep your golf cart running strong you're going to want to charge your batteries after every use. Most new chargers are fully automated, which means they regulate the current so that you do not over-charge your batteries. If you have an older golf cart charger that is not fully automated you would want to set a timer to shut off the charger after your cart is fully charged. A good rule of thumb is to charge it for at least twice as long as you drove it.

Another thing to be aware of is how well your batteries are performing. To keep them in tip-top shape requires proper care. You should be aware of such information as proper water levels and cleaning techniques. The most proactive thing you can do is to take proper safety measures and set up a weekly or monthly schedule to make sure everything is well maintained. One weak battery will bring down all of the otherwise strong batteries to the weakest battery's level, so it makes sense to keep them all properly maintained.

If you want to customize your cart with electrical golf cart accessories, they too will be powered from your golf cart batteries. There are several ways to hook them up, and the best way depends on your particular situation. Most electrical golf cart accessories are 12V accessories, which means they run off of twelve volts. The quick and easy way to power your accessories is to hook them up directly to two of your 6V batteries. But this can cause an imbalance in your battery pack, especially if you have too many accessories requiring too much wattage. At this point it would be better to add a separate auxiliary battery strictly to run your accessories, or a converter to evenly distribute the power from all of your batteries to your accessories.

When it's time to replace your batteries you will need to think about proper golf cart battery disposal. To recycle your old batteries you should take them to a retailer who recycles old batteries for resale. Most retailers that sell lead-acid batteries also take used batteries because it is required by most state laws. Recycling your used golf cart batteries is good for the environment and good for the health of you and those around you.

Pressure Washer Repair

Pressure washers have a lot of parts for effective functioning. The main parts in a pressure washer are the electric or gasoline-powered engine attached to a pump. This pump compresses the water and builds up pressure. The hose has a trigger that has the option of spraying the water either in short bursts or as a continuous spray. The power of the washer depends on the strength of the pump. The nozzle or the tip is also a very important component. This tip can be adjusted at different angels for adjusting the pressure of the water. The smallest angle generates the highest pressure. Larger angles up to 40 degrees are for generating sprays covering larger surface area. Pressure washers also contain a detergent injector that helps to steadily mix the detergent with the water. Other main parts in a pressure washer are the hose, hose reels, valves, heating and cooling components and other plumbing and electrical fittings.

In order to function properly, it is important that all parts are in good working condition. Pressure washers have to be serviced regularly because of the accumulation of dust and grime where they are used. Maintenance involves cleaning the nozzle, which gets clogged with dirt, causing excessive pressure to develop, distorting the spray pattern. Other parts may also develop problems and may have to be replaced from time to time. It is better to consult a hardware technician about pressure washer repair. You can also do a few small repairs and replacements by getting parts from a hardware store. The Internet is a good source of information as well as for buying pressure washer parts. There are several sites that provide useful information about pressure washer repair.

The Top Choice For That Price Range

By far the best M4 airsoft gun under $ 200 would be the G&G combat machines M4. This gun is sold by most online retailers for under $ 175 but do not let that fool you low price, this is not some cheap plastic poor performing gun. What it is is a tough weapon that will shoot 12-14 rounds per second at over 330 feet per second right out of the box!

Why Is It SoInexpensive

It is true that the cost is very low and many people might be wondering why but the truth is to keep costs down the manufacturer used a plastic like nylon fiber where ever they could. This not only keeps costs down but makes a very light gun as well. Even though the construction is nylon fiber there is absolutely no worries when it comes to durability, in fact in tests we have dropped this gun from 8 feet directly onto concrete with no ill effects or damage. That means that on average skirmish situations you will never break the G&G combat machines M4.

How Does It Perform

As I mentioned above the gun fires a tad over 330 FPS with 2 gram BB's and fires in the area of 700 rounds per minute. Not only does it fire fast it is also veryaccurate. When testing this M4 we found that it was easy to hit a man sized target out to 150-175 feet. This will put you right in the sweet spot for being competitive in your next weekend battle! Combine the awesome performance and low price with the legendary G&G quality and you have a true winner!

One FInal Note

One thing you have to keep in mind with the G&G combat machine M4 is that it does not include a battery or charger and you have to buy them separately, so that will add a bit to the price tag. It probably will put you a bit over $ 200 but you will be able to buy a quality battery and charger which will be much better then any stock units that alot of guns come with.

Once you have learned the methods (there are one or two, depending on the type of battery) the costs for battery are extremely low and the effort involved to recondition an old battery very low indeed. If you learn how to recondition a battery, you may even find it to be a profitable business venture on a small or larger scales. Handy resources will be referred to later in the article.

Although it isn't hard to recondition or revive a battery, excellence in anything should never be underestimated. To learn how to fix abattery to its original state, it is crucial to understand the following.

Simple techniques to revive a completely dead battery back to 100% of its original charge capacity (full power) are readily available. It's really not that difficult. Keep in mind that rechargeable batteries enable users to forget about power cables which hinder manipulation of power tools, for example and restrict movement of any device to length of the cable from a power source.

Think about how many devices requiring electricity for power are portable nowadays. Okay, the type of battery may vary-be it for a fork-lift, a cell phone, a golf cart, power tools or iPods, to mention just a few-but for each type of battery, there are quick and easy ways to revive them. I would stress again that the membersare cost effective whether for purely personal use or for business.

To learn how to recondition car batteries, motorcycle batteries, marine batteries and motorized wheelchairs batteries is of great interest for people in all countries. In the States these batteries are expensive for any user and there will be an ever increasing market for reconditioned batteries when the cost of a new one is looked at. Conversely, there exists an ever increasing market in third-world countries where the price of a new battery is also prohibitive.

It is important to take on board that the unhealthy (if not dead) condition of a battery can be due to its charger which frequently malfunctions. But, much more frequently, it is the battery which is murdering the charger. I Knowit is unfortunately common to find people replacing a perfectly good charger, in the belief that the charger is the problem, only to find it destroyed by the real culprit-the battery. Once a battery's ' natural ' lifespan has been exhausted it must be properly reconditioned in order for it not to be a threat to equipment and chargers.

It is also essential to know how to accurately measure the charge capacity of the battery in question. Of course this varies, but once you know precisely how much energy a battery can store at a given time, you can begin to assess the improvement you have made to its performance.

The importance of knowing how to revert to reversed cell cannot be overstated. It is one of the first things to evaluate about a dead battery. You won'tbe able to do anything with it until you have fixed the reversed cell.

One of the best things to understand is exactly why it is that a battery needs reconditioning collector. A new battery develops a memory effect but, guess what, a battery reconditioning collector properly should dispel this effect completely. Now that is some feat and means it is possible to continually rejuvenate suspect batteries.

Battery reconditioning collector requires just a little knowledge and a few cheap tools. It is simply great to use around one's own home and for family and friends. It can even turn into a nice little business. Try this battery reconditioning collector blog for more details: TechnoBlog
