To create a device such as this one would chose a freguency is of a clear band width (avoid the upper frequency FM range) and mke the transmitter sufficiently weak that the signal would practically fade out in 3 meters. It is also possible to check the signal strength on the receiving circuit though this is prbably more sophisticated then need be as if you sufficiently under power, via gues nd check you should obtain the desired range.

A chemical used to absorb moisture. It is silica gel. It absorbs moisture. The following is from a poison control site: ''Question'': What is harmful about silica gel? ''Answer'': Silica gel is not toxic to humans. There is a warning sign on the packaging because it is considered a choking hazard. If children accidentally ingest silica gel, gently wipe out their mouth and give them something to drink to take away the bad taste. It's called desiccant. Do not eat iPod Shuffle. (sorry, BS answer, I know, but couldn't resist) Actually, it's a desiccant of some sort. A desiccant absorbs moisture so that whatever it's packed with will have reduced exposure to said moisture, thus helping to keep metal from rusting, pills from ruining, and electronics from shorting out. (Wikipedia) A desiccant is a substance that adsorbs water. It is most commonly used to remove humidity that would normally degrade or even destroy products sensitive to moisture

This is a signal that you most likely have a bad solder joint in your component. If both speakers are failing to play, then the issue is actually at the stero end. If only one speaker is doing this, then most likely the problem is at the speaker, but it could still be at the stereo itself. The reason it works when it is hot is that the heat causes the metal in the solder or immediate component to expand thus completing the circuit. As it cools off the circuit is broken again because the metal has contracted and is no longer making a complete circuit.

You cannot use most fluorescent lights with a dimmer. Just about any incandescent bulb WILL work with a dimmer. Occasionally, when a halogen bulb burns out, it will destroy a dimmer switch but halogen bulbs are considered incandescent and other than that little problem they work well with a dimmer.

Apparently ions help the hair dry faster with less heat, which can damage hair. I'm not sure there's a lot of evidence to support it, though.

The loopback address is 127.0.0.1. It is also called 'localhost'. It's purpose is simple: It's the most rudimentary test for functionality of your NIC (Network Interface Card). For example, if you ping 127.0.0.1 OR ping localhost you'll get a response IF your NIC is enabled, connected to something (physical network or wireless) and working. Problems with localhost pinging usually means a problem with the NIC itself. Google Web Accelerator, Hello, and some other tools take advantage of the loopback address for functionality. They open a port on loopback to internally 'host' web pages. Google Web Accelerator for example, creates a local cache of your web pages, and sets your proxy to the loopback address on a specific port, so that you get the local cache first, giving the illusion of instantaneous loading of the page.

No power is used in the turning on and off process. If it is on you are using electricy if it's off you are not. It doesn't heat up or cooldown in the sense of a gradual thing. On, off, no inbetween.+

While properly grounded (to prevent static electricity buildup and damage to the electronic components) gently push downward on the chip.

Remove the card from the expansion slot and use a screwdriver to press down firmly on each corner of each socketed chip on the card. Chips sometimes loosen because of thermal changes; this condition is called chip creep.

Yes, you can, but you need to put a resistance in series with the battery to limit the maximum current, so you don't overheat and cook the battery.

I tend to fast charge my batteries using a 12v light bulb / utility light to lower the current. The bulb will glow when the battery is taking heavy current, and as the battery builds up charge, the current will drop and the bulb will get dimmer and dimmer.

I try to limit the current to 1/10 of the capacity of the battery Im charging if I can.

Otherwise, I monitor it with an ammeter and voltmeter and watch the lightbulb.

A type of earphone which has a central earphone transducer coupled to both ears by acoustic tubes in a Y-formation like that of a traditional stethoscope. The word may have been a registered trademark in UK at one time, but it appears not to be now. The mark owner may well be no longer in business.

The reason is due to the WEEE regulations (Waste electrical electronic equipment). All electrics used to be sent to landfill where as now it is segregated and forwarded on to specialist outlets who recycle what they can. Examples of WEEE are * Household appliances * IT & telecoms equipment * Audio-visual and lighting equipme * Electronic & electrical tools * Toys, leisure & sports equipment * Medical devices * Automatic dispensers

Probably not as the case needs the air to be able to circulate around it , a PC runs hot and needs to cool itself with the fans inside of it. Place it on a board if you must set it on the floor. A carpet is an insulation and will keep some of the heat in. Cooler is better with a computer.

Another factor that appears when a tower is located on carpet is dust. Carpet caches dirt and dust better than most people think. The airflow of your fans and cooling system inside your tower can suck this into the case, covering the delicate array of electronics over time. This may increase the running temperature of certain processors, including your CPU, GPU and NICs which increases their likelihood of failure. Dust covered circuits are also more prone to static buildup, which may discharge and short components during startup and shutdown of the tower.

Lithium iron phosphate (LiFePO4) batteries are known for their flat discharge rate, meaning they provide stable voltage output throughout the majority of their discharge cycle. This characteristic makes them ideal for applications requiring consistent power delivery, such as electric vehicles and solar energy storage systems.

It probably means that it is a LightScribe disk, which allows certain DVD burner to print a label on them.

This usually refers to radio sgnals and often concerns the antenna but could also concern the type of radio aparatus.

The volt is named for Count Alessandro Giuseppe Antonio Anastasio Volta, an Italian physicist who invented the first electric cell in 1800.

It will lose its magnetic properties.Indeed you are right...but in addition, during the process of intense increase in temperature, the magnet starts to lose its magnetism thereafter it utterly loses it magnetism, but starts to to regain its magnetism back as it cools. I recently discovered this after two trials with my stove. I propose that magnets may utterly lose their magnetism when exposed to temperatures beyond 800 degree Fahrenheit subsequently after the metal liquefies.

NAND stands for 'Not And', which means the output will send a signal so long as both inputs aren't on. (If both inputs A and B are 1, then the output is 0. All other combinations give an output of 1)

Normally you would have to put batteries and then place your CD in and then press the play button. That is all I do to start mine.

It's supposed to be under the hood on Stud #2 30 amp. I tested mine and the fuse is good and the block has power, but I get no power in the plug in the rear still :(

HID or high intensity DISCHARGE lamps are lamps without filaments. They work as a gas discharge system which means that they work similar to a flourescent tube, in that they have a ballast system which provides a start-up voltage and then settles down to a running voltage once the lamp is ignited..

The lamp itself usually consists of a quartz shell, filled with some type of gas such as argon, zenon, etc. As a result, they are capable of putting out some serious lumens. The big drawback is that they usually don't last as long as regular incandescent lamps or LED's, and are more expensive to replace.

One main reason is that it helps power Automatic External Defibrillators otherwise known as AED's. These devices are only used in an emergency though. Other examples of electricity saving lives would be Smoke Detectors (batteries), ICD's (Internal Cardiac Defibrilators, Air Bags, Alarms, Ambulance Power Systems, Assisted Breathing Machines, Artificial Kidneys, And much much more.

Ku band, (Transmit frequency 13.75 to 14.50 GHz, Receive frequency 10.70 to 12.75 GHz dependant on which region of the earth you live in) is used rather than C band (4 to 6 GHz) because the higher frequency allows for broader transmit and receive bandwidths, so more data, computer traffic, movies, etc can be sent. The signal power lost in transmitting from earth to the satellite and back to earth again varies with frequency, but not as a simple linear sloping line increasing with frequency way, it has peaks and troughs. This is because at some frequencies Oxygen and Water absorb much more power and it is difficult to generate enough power to pass a strong signal through the atmosphere, so those frequencies are avoided. Ku band uses a part of the frequency spectrum with a lower atmospheric loss between earth and space, so relatively less microwave power is needed to efficiently transmit to and from the satellite.
