Retrotronics
Retrotronics (a portmanteau of "retro" and "electronics", also ''retro-tronics'') is the making of electric circuits or appliances using older electric components, such as vacuum tubes, Nixie displays, relays, uniselectors, analogue meters, etc. These are usually chosen more for their aesthetic qualities than performance. Retrotronics is a popular strand within the steampunk movement. At the Oxford exhibition of Steampunk art, a third of the works on show had a strong retrotronic influence, from light fittings of period components through to computer keyboards and webcams of burnished copper and brass. Outside steampunk, similar influences are found amongst the retro-futurist scene. Other sources cite the Maker movement as an influence. A recent musical trend has sought to recapture early 1980s 8-bit game and synthesiser sounds, often referred to as chiptune. Artists such as Kid Carpet perform entire sets on children's toys or pocket synths of the period. Other artists, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Retro-futurist
Retrofuturism (adjective ''retrofuturistic'' or ''retrofuture'') is a movement in the creative arts showing the influence of depictions of the future produced in an earlier era. If futurism is sometimes called a "science" bent on anticipating what will come, retrofuturism is the remembering of that anticipation. Characterized by a blend of old-fashioned "retro styles" with futuristic technology, retrofuturism explores the themes of tension between past and future, and between the alienating and empowering effects of technology. Primarily reflected in artistic creations and modified technologies that realize the imagined artifacts of its parallel reality, retrofuturism can be seen as "an animating perspective on the world". Etymology The word retrofuturism is formed by the addition of the prefix "retro" from the Latin language, which gives the meaning of "backwards" to the word "future", a word also originating from Latin. According to the ''Oxford English Dictionary'', an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steampunk
Steampunk is a subgenre of science fiction that incorporates retrofuturistic technology and Applied arts, aesthetics inspired by, but not limited to, 19th-century Industrial Revolution, industrial steam engine, steam-powered machinery. Steampunk works are often set in an alternate history, alternative history of the Victorian era or the American frontier, where steam power remains in mainstream use, or in a fantasy world that similarly employs steam power. Steampunk features anachronism, anachronistic technologies or retrofuturistic inventions as people in the 19th century might have envisioned them — distinguishing it from Neo-Victorianism — and is likewise rooted in the era's perspective on fashion, culture, architectural style, and art. Such technologies may include fictional machines like those found in the works of H. G. Wells and Jules Verne. Other examples of steampunk contain alternative-history-style presentations of such technology as steam cannons, lighter-than-ai ...

Electrolytic Capacitor
An electrolyte is a substance that conducts electricity through the movement of ions, but not through the movement of electrons. This includes most soluble Salt (chemistry), salts, acids, and Base (chemistry), bases, dissolved in a polar solvent like water. Upon dissolving, the substance separates into cations and anions, which disperse uniformly throughout the solvent. Solid-state electrolytes also exist. In medicine and sometimes in chemistry, the term electrolyte refers to the substance that is dissolved. Electrically, such a solution is neutral. If an electric potential is applied to such a solution, the cations of the solution are drawn to the electrode that has an abundance of electrons, while the anions are drawn to the electrode that has a deficit of electrons. The movement of anions and cations in opposite directions within the solution amounts to a current. Some gases, such as hydrogen chloride (HCl), under conditions of high temperature or low pressure can also functi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GPO Telephones
The General Post Office (GPO) of the United Kingdom carried the sole responsibility for providing telecommunication services across the country with the exception of Hull. The GPO issued a range of telephone instruments to telephone service subscribers that were matched in function and performance to its telephone exchanges. General history Until October 1969, the GPO had a monopoly on the provision of all telephone lines and telephones within the UK, other than in Kingston upon Hull, which for historical reasons was unique in maintaining its own municipal telephone service. From the 1st of October 1969, the Post Office Corporation replaced the General Post Office with ownership of the former GPO business. Customers of the PO (known internally as "subs", short for 'subscribers') did not own their telephones. They were instead rented from the GPO, together with the house wiring and the wiring connecting the house to the local network at a connection point known as a DP (distributi ...

BT Group
BT Group plc (formerly British Telecom) is a British Multinational corporation, multinational telecommunications holding company headquartered in London, England. It has operations in around 180 countries and is the largest provider of fixed-line, Internet access, broadband and Mobile telephony, mobile services in the UK, and also provides subscription television and Information technology, IT services. BT's origins date back to the founding in 1846 of the Electric Telegraph Company, the world's first public telegraph company, which developed a nationwide communications network. BT Group as it came to be started in 1912, when the General Post Office, a government department, took over the system of the National Telephone Company becoming the monopoly telecoms supplier in the United Kingdom. The Post Office Act of 1969 led to the GPO becoming a public corporation, Post Office Telecommunications. The ''British Telecom'' brand was introduced in 1980, and became independent of the R ...

Bakelite
Bakelite ( ), formally , is a thermosetting polymer, thermosetting phenol formaldehyde resin, formed from a condensation reaction of phenol with formaldehyde. The first plastic made from synthetic components, it was developed by Belgian chemist Leo Baekeland in Yonkers, New York, in 1907, and patented on December 7, 1909. Bakelite was one of the first plastic-like materials to be introduced into the modern world and was popular because it could be Molding (process), molded and then hardened into any shape. Because of its electrical nonconductor, nonconductivity and heat-resistant properties, it became a great commercial success. It was used in electrical insulators, radio and telephone casings, and such diverse products as kitchenware, jewelry, pipe stems, children's toys, and firearms. The retro appeal of old Bakelite products has made them collectible. The creation of a synthetic plastic was revolutionary for the chemical industry, which at the time made most of its income f ...

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] |
Vox AC30
The Vox AC30 is a Instrument amplifier, guitar amplifier manufactured by Vox (company), Vox. It was introduced in 1958 to meet the growing demand for louder amplifiers. Its "jangly" high-end sound made it widely used by British musicians and others, including George Harrison and John Lennon of the Beatles, Bill Wyman of the Rolling Stones, Brian May of Queen (band), Queen, Dave Davies of the Kinks and Hank Marvin. History Vox's original flagship amplifier was the 15-watt AC15, powered by a pair of EL84 Vacuum tube, tubes, an EZ81 rectifier, an EF86-driven "Normal" channel, an ECC83-driven "Vib-Trem" channel. After the AC15 proved too weak to be heard over the screaming fans at Cliff Richard's concerts, Hank Marvin asked Vox to build a "big brother". Introduced in 1959, the first-generation AC30 used EL84 tubes, a GZ34 tube rectifier, three ECC83s (12AX7) for the Normal channel and the tremolo/vibrato oscillator/modulator circuits and one ECC81 (12AT7) phase inverter.

Guitar Amplifiers
A guitar amplifier (or amp) is an electronic device or system that strengthens the electrical signal from a pickup on an electric guitar, bass guitar, or acoustic guitar so that it can produce sound through one or more loudspeakers, which are typically housed in a wooden cabinet. A guitar amplifier may be a standalone wood or metal cabinet that contains only the power amplifier (and preamplifier) circuits, requiring the use of a separate speaker cabinet–or it may be a ''combo'' amplifier, which contains both the amplifier and one or more speakers in a wooden cabinet. There is a wide range of sizes and power ratings for guitar amplifiers, from small, lightweight practice amplifiers with a single 6-inch speaker and a 10-watt amp to heavy combo amps with four 10-inch or four 12-inch speakers and a 100-watt amplifier, which are loud enough to use in a nightclub or bar performance. Guitar amplifiers can also modify an instrument's tone by emphasizing or de-emphasizing certain fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
