Computer Case Modding

Case modding is the artistic modification of the computer (often referred to as case), often also involving peripheral components. Many people, Particulary hardware enthusiasts use case mods for computers illustate power. Terminology of "fashion" is short for "modification".

The history of computer cases

When personal computers hit the mainstream, most of them came in the case, the color beige. This functional design was often called the beige box While this served the purpose of containing the components of a personal computer, as time went on, many users find their computers to be "sticky" or "stupid" at the lack of originality in the design of the case. Thus, to solve this problem, some users have begun to modify existing chassis or build their own.

Later, in the case when it became mainsteam IMac Apple has been released, which went against the beige box design in those days. Since then, many computer manufacturers began to sell the cases that the absence of boring beige base. Case modification has also opened a new market for third party computer cases continue to break in the average case. Beige cases are now becoming harder to find as users enjoy the great variety of colors and styles, current affairs OEM.

LED technology and computer modding: What you should know when the lighting on your computer

Physical function
Indicator of a special type of semiconductor diode. As a normal diode, it consists of a chip of semiconductor material impregnated, or doped, with impurities to create a structure called the PN-junction. Charge-carriers - electrons and holes flow in the junction from electrodes with different voltages. When an electron meets a hole, he falls into a lower energy level and releases energy in the form of photons, as he does it.

Light Emission
The wavelength of light emitted, and therefore its color, depends on the energy gap materials forming PN-junction. Normal diode, typically made of silicon or germanium, emits invisible far-infrared light, and the materials used for LED have bandgap energies corresponding to near-infrared, visible or near UV light.

Considerations in the use of LED lights in the computer cases
Unlike incandescent bulbs, which can operate with AC or DC, LEDs require a constant supply proper electrical polarity. When the voltage across the PN junction in the right direction, significant current and the device is called a forward direction. If the voltage of reverse polarity, the device is called a reverse-biased, very little current flows, and no light. Most LEDs have low reverse breakdown voltage ratings, and will be damaged by the applied reverse voltage of more than a few volts.

Because the voltage-current characteristics of the LED is much like any diode, they may be destroyed by connecting them to a voltage source higher than the turn on voltage. A good indicator driver circuit or DC power source or an approximation to the current source made by connecting LEDs in series with current limiting resistor for the voltage source. Voltage drop forward biased LEDs can vary significantly based on the current thread.
