Whether you need bluetooth

When buying any digital electronic device, whether a cellphone, PDA, or notebook computer, it is important to check the specifications to ensure that it will serve your purposes. Bluetooth is becoming an increasingly popular offering in personal electronics, but do you need it?

What Is Bluetooth?

Bluetooth is a wireless PAN (Personal Area Network) transmission protocol standard. In layman’s terms, Bluetooth is a technology that enables a device to communicate and share data with other Bluetooth capable devices – cellphones, headsets, PDAs, notebook computers, desktop PCs, computer peripherals, printers, cameras, and others – through radio wave transmission (so there is no need for wires) at a range of around 1, 10, or 100 meters, depending on the class of your Bluetooth device (Class 1 has the longest range and Class 3 the shortest).

If a device has a Bluetooth chip, it can communicate with other devices that have a Bluetooth chip. Users can share pictures, movies, datasheets, documents, and all sorts of information among them as long as their devices are in range (they do not need to be in direct line of sight). For instance, a Bluetooth-capable digital camera can communicate with a Bluetooth-capable printer for direct printing. Likewise, a Bluetooth-capable cellphone can be connected to a Bluetooth-equipped headset so that a person can take and make hands-free telephone calls.

Bluetooth can be used for internet connectivity as long as a bluetooth-enabled computer is in range of a Bluetooth modem. Bluetooth devices can also form a small wireless network (called a piconet) of up to 8 devices. For security, devices can be paired and transmissions encrypted. So that it causes only minimal interference, Bluetooth periodically changes frequency channels.

Bluetooth uses the same radio frequency that 802.11 Wireless Networking does, but it is much simpler than 802.11 technology, negating the need for complex network configurations. Bluetooth also has lower power consumption, making it more economical, though its range is shorter.

You Need Bluetooth

If you wish to have an extremely basic home network, Bluetooth is for you. There are no wires to trip you and there are no complex configurations like network permissions or addresses to deal with. Piconets are temporary, so a new device can immediately join or leave a Bluetooth network with nothing more than a simple device discovery. It is important to note, however, that piconets are no substitution for a traditional home network (whether through Ethernet or 802.11 Wireless), which are much more reliable and offer much more full-bodied security options.

If you have a notebook computer, there is a good chance you will want to have Bluetooth connectivity so that you can take advantage of the many Bluetooth-equipped peripherals, thereby eliminating the need for bulky wires. You can also easily synchronize data between your handheld devices and your notebook computer. Moreover, if you are fond of sharing data with other handheld device users, you definitely need to have Bluetooth for easy and convenient data sharing.

You Don’t Need Bluetooth

It is important to note that bluetooth can present a security risk if you store sensitive information on your Bluetooth-enabled device. If you are traveling with sensitive information on your computer, cell-phone, or PDA, it is wise to disable Bluetooth temporarily to prevent data theft or exploitation. Please also note that some corporations and government entities disapprove of bluetooth and similar convenience-based additions, so please check with your employer if you intend to use your Bluetooth-enabled notebook for business.

Light Up Your Wheels With the Help of LED Lights

Wheel well LED lights emit a illuminating glow from the wheel wells of your truck or car, making them stand out and get noticed. There are several manufacturers of LED lights, and these include Streetglow, PlasmaGlow, and Varad, among others. The colors that are available are numerous, including blue, purple, green, pink, and almost every other color of the rainbow. These lights come in single colors and in multicolor and changing color models as well. There is even one model that boasts 2.1 million colors as the LED lights cycle through their entire color spectrum on a regular basis. If you choose a model that has the ability to change colors, make sure you still have the option to set it on a single color as well, so that you can switch between the two modes as needed.

The laws vary regarding LED lights, with some areas allowing them, some areas restricting their use, and some areas completely banning this light accessory on your vehicle.

Municipalities, cities, and states all have the right to set their own laws regarding these matters, so the law can be completely different in cities that are only fifteen or twenty miles apart. Some places only ban specific colors, like red and blue, with the reasoning that the LED lights could cause confusion, because most public vehicles like ambulances, police cars, and fire trucks use these colors. Other places have restricted the use of changing colors and colors that strobe or pulse, with the reason that these devices can cause a distraction, making other drivers concentrate less on driving, which can lead to accidents. Some areas restrict the exact location these lights can be placed on the vehicle, limiting them to specific areas but not others.

It is a wise move to contact your local authorities, like the police department or city hall, to find out what the specific law is in your area. Otherwise, that great light kit could cost you significantly more in tickets and legal costs.

Wheel well LED light kits can vary in price, depending on the brand name as well as the model. Normally, for a couple hundred dollars you can get a top name brand and multiple colors in a light kit. These lights are very easy to install and come with very detailed easy to follow instructions. Each kit normally includes a flexible light bar for each of your 4 wheel wells.

These normally mount at the top of your wheel well, cascading a soft glow of color over your entire wheel well area and tire. The light bars connect to a standard 12 volt power source, usually your vehicle battery, and there is no special knowledge or experience needed to install them. The installation process may take quite a bit of time, especially if this is your first installation attempt with wheel well lights. Some people may not be comfortable in attempting this installation process, and if that is the case, then any car accessory dealer can install the lights for you at a reasonable cost.

Wheel well LED lights can be a great way to make your car stand out and become the center of attention. With the soft glow illuminating the wheel wells and tires of your car, every eye will be drawn to it. Some models allow the lights to change, pulse, strobe, and blink, making your vehicle a driving light show. These lights are great to use on a car that you drive every day, as well as a car that is shown in auto shows for competition. These lights can greatly improve the customized look of your automobile. These LED lights can be used alone, or with numerous other lighting and automotive accessories in a mix and match style, to give your car that unique, one of a kind look. These lights are fabulous ways to make the look of your car match your personality.

Gemstone Enhancement and Treatment

Some of treatment procedures are centuries old, while others are relatively new. Gemstone are treated in different ways to improve their appearance. Some of these procedures are centuries old, while others are relatively new. Also, by cutting or polishing gemstone could have fabulous colors and nice sparkle. Treatment or enhancement gemstones means any process to make natural gems improved gem’s color, clarity before cutting and polishing. Please understand that TREATMENT AND ENHANCEMENT has nothing to do with man created gems or synthetic gems. Treating and enhancing gemstone is a very common step to improve gems appearance. Some treatment and enhancement improved by nature are permanent and cannot be detected. Treatment and enhancement procedure so closely resembles what happens in nature, that one cannot always tell if they have been treated after mining or before. Microscopic examination will sometimes reveal an inclusion that burst during heating treatment, but lacking that there is no way to tell exact that heat treatment was done before or after mining. There are many techniques of treated or enhanced gems (More knowledge at http://www.facedgem.com/gemstone-knowledge/gemstone-treatment.htm). Briefly explanations of the important techniques is given below.

Oiling treatment method has been used form more than hundreds years, mostly emerald treated to derive its beautiful green color and clarity. In the same way, other colored stones such as alexandrite and rubies have been treated this way makes less surface inclusions. So we can concluded that colored oils are used on those gemstone to improve their appearances. This treatment reduces fractures and provide better clarity. Heat treatment is the most common form and famous enhancement. This is so common with corundum, ruby and sapphire, it is recommended that jewelers inform their customers that they are “probably heat treated”. Heating can cause color of a stone to darken, lighten, or even completely changed and can also improve gems clarity and brightness. Heating of most kinds of gemstones is a standard treatment procedure. Heating knowledge was passed over generations. Heating Methods vary from simply burning method to highly techniques under regulate temperature (More knowledge at http://www.facedgem.com/gemstone-knowledge/gemstone-treatment.htm). Diffusion is an enhancement method, commonly used on corundum, added iron and titanium during the heating process of the gemstone, sometime called surface diffusion. Diffusion layer created by adding elements. This layer described as colored coating. Radiation enhancement or irradiation means pounding material with subatomic particles. In some case, irradiation is followed by heating to produce a better or new color for the gem – such as topaz. Today so many irradiation technique applied and has created shades that cannot found in natural topaz. Same way in tourmaline, irradiation can turn dark pink stone into red. For diamonds irradiation and heating can turned them into browns, blues, yellows, pinks and greens.

Playing Mp3s In The Car

Whether on the way to work, to drop the kids off at school, or going to the grocery store, everyone has a favorite radio station that they listen to while in the car. If its like most stations, they’ve got a mix of music that is hard to not sing along with and they probably claim to play 90 minutes of pure music with no commercial interruption. Yet somehow it seems like every time the car starts up those 90 minutes have just came to an end. Perhaps it is time to leave the commercials — and the 20th century — behind and connect an MP3 player to the car stereo.

To solve the problem of playing MP3s in a car, there are a few different solutions. For those cars with stereos old enough to have a cassette player, the best option is simply an adapter. Most every electronics retail store sells cassette adapters. These adapters plug into the headphone jack of the MP3 player (or virtually any other similar device) and a cassette-shaped converter is inserted into the car’s tape player. This way the signal travels directly through the headphone jack, through the adapter cassette, and then through the car stereo, giving the great sound and music selection received from a digital audio player.

Another option is to get an FM transmitter that turns an MP3 player into a miniature FM station. This is a less than perfect solution, and requires a few very important things to be considered. Most FM transmitters offer only a few specific frequencies to transmit the signal. The cheapest ones broadcast on 88.0 through 89.0 FM exclusively. If there is a major local station nearby within that band it is likely this station’s broadcast will interfere with the operation of such a FM transmitter. Higher-quality transmitters will give the freedom to choose from a wider selection of frequencies, making it easier to find one that is far enough from a powerful signal to come in clearly on the car’s radio tuner.

The final option is to have a factory radio adapter installed in the car, which allows the audio to be used to its fullest extent. These adapters are far more expensive than simple external adapters and generally require some installation that may have to be done professionally. While this style of solution can be found at most major electronics retail outlets, it may be more desirable to order them online where they are more readily available.
