new TV‚ or building a home theater‚ then there is quite a bit of research to be done before you make the plunge. Right now‚ as many of you may know‚ there are two competing technologies for High Definition Flat Screen TV. The first is LCD‚ or Liquid Crystal Display and the other is Plasma TV. You may be asking yourself which technology is better? What are their prospective pros and cons? Well‚ before I get into what you should buy‚ you should get the “how does it work run down”‚ the quick and

Arduino Kit Arduino is a tool for making computers that can sense and control more of the physical world than your desktop computer. It’s an open-source physical computing platform based on a simple microcontroller board‚ and a development environment for writing software for the board. The Arduino programming language is an implementation of Wiring‚ a similar physical computing platform‚ which is based on the Processing multimedia programming environment. ATmega128 The ATmega is an MCU produced

The cost of a single chip DLP projector ranges from $338.99 to $1799. The three chip DLP projector cost anywhere from $15‚995 to $36‚979. Another data projector is the LCD projector. With an LCD projector light passes through panels of liquid crystals. Each panel is for a different color; red‚ green‚ and blue. With these three panels approximately 16.7 million colors can be

TV. There are two types of monitors on the market today‚ CRT and LCD. CRT Monitors or Cathode Ray Tube uses a tube similar to old television screens. CRT Monitors contain an electric charged storage capacitor‚ deadly if touched. LCD Monitors or Liquid Crystal Display uses TFT technology or Active Matrix. There are several specifications to conceder when choosing a monitor. Such as Screen Size‚ Contrast Ratio‚ Refresh Rate Interlacing (CRT)‚ Response Time (LCD)‚ Resolution‚ and much more.

Dark Crystal Jim Henson’s pride and joy is one of his less famous works‚ a fantasy film named Dark Crystal that was filmed completely with originally made puppets. The film is complete with heroes‚ villains and the other main components of fantastical narratives as described by folklorist Vladimir Propp who states that in fairytale narratives there are 31 functions. A function is defined as‚ “an act of a character‚ defined from the point of view of its significance for the course of the action”

A PIC16F628 is used and the results are output to an alphanumeric liquid crystal display (I.c.d.). One technique for using an inductor in a CMOS oscillator circuit is that shown in Fig.1.Here the oscillation frequency is determined by the formula: F = _______1_______ 2 x 7 x / ( L x C ) where: F = frequency C = C1 x C2
