Magnavox Odyssey
The Magnavox Odyssey is the first commercial home video game console. The hardware was designed by a small team led by Ralph H. Baer at Sanders Associates, while Magnavox completed development and released it in the United States in September 1972 and overseas the following year. The Odyssey consists of a white, black, and brown box that connects to a television set, and two rectangular game controller, controllers attached by wires. It is capable of displaying three square dots and one line of varying height on the screen in monochrome black and white, with differing behavior for the dots depending on the game played. Players place plastic overlays on the screen to display additional visual elements for each game, and one or two players for each game control their dots with the knobs and buttons on the controller by the rules given for the game. The console cannot generate audio or track score (game), scores. The Odyssey console came packaged with dice, paper money, and other b ...

Game Controller
A game controller, gaming controller, or simply controller, is an input device or Input/Output Device, input/output device used with video games or entertainment systems to provide input to a video game. Input devices that have been classified as game controllers include Computer keyboard, keyboards, Computer mouse, mice, gamepads, and joysticks, as well as special purpose devices, such as steering wheels for Racing video game, driving games and light guns for Shooter game, shooting games. Controllers designs have evolved to include D-pad, directional pads, multiple buttons, analog sticks, joysticks, motion detection, touch screens and a plethora of other features. Game controllers may be input devices that only provide input to the system, or Input/Output Device, input/output devices that receive data from the system and produce a response (e.g. Haptic technology, "rumble" vibration feedback, or sound). Controllers which are included with the purchase of a home console are refer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calendar Year
A calendar year begins on the New Year's Day of the given calendar system and ends on the day before the following New Year's Day, and thus consists of a whole number of days. The Gregorian calendar year, which is in use as civil calendar in most of the world, begins on January 1 and ends on December 31. It has a length of 365 days in an ordinary year but, in order to reconcile the calendar year with the astronomical cycle, it has 366 days in a leap year. With 97 leap years every 400 years, the Gregorian calendar year has an average length of 365.2425 days. Other formula-based calendars can have lengths which are further out of step with the solar cycle: for example, the Julian calendar has an average length of 365.25 days, and the Hebrew calendar has an average length of 365.2468 days. The Lunar Hijri calendar ("Islamic calendar") is a lunar calendar consisting of 12 lunar months in a year of 354 or 355 days. The astronomer's mean tropical year, which is averaged over e ...

Transistor
A transistor is a semiconductor device used to Electronic amplifier, amplify or electronic switch, switch electrical signals and electric power, power. It is one of the basic building blocks of modern electronics. It is composed of semiconductor material, usually with at least three terminal (electronics), terminals for connection to an electronic circuit. A voltage or Electric current, current applied to one pair of the transistor's terminals controls the current through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal. Some transistors are packaged individually, but many more in miniature form are found embedded in integrated circuits. Because transistors are the key active components in practically all modern electronics, many people consider them one of the 20th century's greatest inventions. Physicist Julius Edgar Lilienfeld proposed the concept of a field-effect transisto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diode–transistor Logic
Diode–transistor logic (DTL) is a class of digital circuits that is the direct ancestor of transistor–transistor logic. It is called so because the logic gating functions AND and OR are performed by diode logic, while logical inversion (NOT) and amplification (providing signal restoration) is performed by a transistor (in contrast with resistor–transistor logic (RTL) and transistor–transistor logic (TTL). Implementations The DTL circuit shown in the first picture consists of three stages: an input diode logic stage (D1, D2 and R1), an intermediate level shifting stage (R3 and R4), and an output common-emitter amplifier stage (Q1 and R2). If both inputs A and B are high (logic 1; near V+), then the diodes D1 and D2 are reverse biased. Resistors R1 and R3 will then supply enough current to turn on Q1 (drive Q1 into saturation) and also supply the current needed by R4. There will be a small positive voltage on the base of Q1 (VBE, about 0.3 V for germanium an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sound Effect
A sound effect (or audio effect) is an artificially created or enhanced sound, or sound process used to emphasize artistic or other content of films, television shows, live performance, animation, video games, music, or other media. In motion picture and television production, a sound effect is a sound recorded and presented to make a specific storytelling or creative point ''without'' the use of dialogue or music. Traditionally, in the twentieth century, they were created with Foley (filmmaking), Foley. The term often refers to a process applied to a recording, without necessarily referring to the recording itself. In professional motion picture and television production, dialogue, music, and sound effects recordings are treated as separate elements. Dialogue and music recordings are never referred to as sound effects, even though the processes applied to such as reverberation or flanging effects, often are called ''sound effects''. This area and sound design have been s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alternating Current
Alternating current (AC) is an electric current that periodically reverses direction and changes its magnitude continuously with time, in contrast to direct current (DC), which flows only in one direction. Alternating current is the form in which electric power is delivered to businesses and residences, and it is the form of electrical energy that consumers typically use when they plug kitchen appliances, televisions, Fan (machine), fans and electric lamps into a wall socket. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', respectively, as when they modify ''Electric current, current'' or ''voltage''. The usual waveform of alternating current in most electric power circuits is a sine wave, whose positive half-period corresponds with positive direction of the current and vice versa (the full period is called a ''wave cycle, cycle''). "Alternating current" most commonly refers to power distribution, but a wide range of other appl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
C Battery
The C battery (C size battery or R14 battery) is a standard size of dry cell battery typically used in medium-drain applications such as toys, flashlights, and musical instruments. As of 2007, C batteries accounted for 4% of alkaline primary battery sales in the United States. In Switzerland as of 2008, C batteries totalled 5.4% of primary battery sales and 3.4% of secondary (rechargeable) battery sales. Properties A C battery measures length and diameter. The voltage and capacity of a C-size battery depends on the battery chemistry and discharge conditions. The nominal voltage is 1.5V. Alkaline C batteries have a storage capacity up to 8000 mAh while rechargeable NiMH C batteries can hold up to 6000 mAh. Zinc-carbon C batteries usually hold up to 3800 mAh. Compared to the AAA and AA batteries, C-batteries' storage capacities are significantly higher. Standardisation Like the D battery, the C battery size has been standardized since the 1920s.Ron Runkles (ed) ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Control Knob
{{more citations needed, date=January 2017 A control knob is a rotary device used to provide manual input adjustments to a mechanical/ electrical system when grasped and turned by a human operator, so that differing extent of knob rotation corresponds to different desired input. Control knobs are a simpler type of input hardware and one of the most common components in control systems, and are found on all sorts of devices from taps and gas stoves to optical microscopes, potentiometers, radio tuners and digital cameras, as well as in aircraft cockpits.https://www.amazon.com/b?node=16412811 Operation A control knob works by turning a shaft which connects to the component which produces the actual input. Common control components used include potentiometers, variable capacitors, and rotary switches. An example where the knob does not produce a variation in an electrical signal may be found in many toasters, where the darkness knob moves the thermostat A thermostat ...

First Generation Of Video Game Consoles
In the history of video games, the first generation era refers to the video games, video game consoles, and handheld video game consoles available from 1972 to 1983. Notable consoles of the first generation include the Odyssey series (excluding the Magnavox Odyssey 2), the Atari Home Pong, the Coleco Telstar series and the Color TV-Game series. The generation ended with the Computer TV-Game in 1980 and its following discontinuation in 1983, but many manufacturers had left the market prior due to the market decline in the year of 1978 and the start of the second generation of video game consoles. Most of the games developed during this generation were hard-wired into the consoles and unlike later generations, most were not contained on removable media that the user could switch between. Consoles often came with accessories and cartridges that could alter the way the game played to enhance the gameplay experience as graphical capabilities consisted of simple geometry such as ...

Pong
''Pong'' is a 1972 sports video game developed and published by Atari for arcades. It is one of the earliest arcade video games; it was created by Allan Alcorn as a training exercise assigned to him by Atari co-founder Nolan Bushnell, but Bushnell and Atari co-founder Ted Dabney were surprised by the quality of Alcorn's work and decided to manufacture the game. Bushnell based the game's concept on an electronic ping-pong game included in the Magnavox Odyssey, the first home video game console. In response, Magnavox later sued Atari for patent infringement. ''Pong'' was the first commercially successful video game, and it helped to establish the video game industry along with the Magnavox Odyssey. Soon after its release, several companies began producing games that closely mimicked its gameplay. Eventually, Atari's competitors released new types of video games that deviated from ''Pong'''s original format to varying degrees, and this, in turn, led Atari to encourage its sta ...
