Hacker Radio Ltd
Hacker Radio Limited manufactured domestic radio and audio equipment. The company was formed in Maidenhead by brothers Ron and Arthur Hacker in 1959, and traded successfully until 1977. Financial difficulties resulted in the company being sold and relaunched with the name Hacker Sound which closed in 1979. History The Hacker brothers, Ron (born 1908) and Arthur (born 1910), founded Dynatron in the late 1920s with help from their father Harry, but in 1955 Ekco took over the company, which at the time employed 150 people. By 1959, the number of employees had risen to 250, but the Hacker brothers were uncomfortable with the arrangements and decided to set up their own company, Hacker Radio Limited. In December 1960 Ekco merged with Pye, then Pye was bought by Philips in 1967. In 1981, Roberts Radio bought Dynatron from Philips. The Hacker brothers acquired a factory in Cox Green, Maidenhead, and started producing a range of transistor portable radios, beginning with the RP10 Her ...

Hacker Sound
A hacker is a person skilled in information technology who uses their technical knowledge to achieve a goal or overcome an obstacle, within a computerized system by non-standard means. Though the term ''hacker'' has become associated in popular culture with a '' security hacker''someone who utilizes their technical know-how of bugs or exploits to break into computer systems and access data which would otherwise be inaccessible to them – hacking can also be utilized by legitimate figures in legal situations. For example, law enforcement agencies sometimes use hacking techniques in order to collect evidence on criminals and other malicious actors. This could include using anonymity tools (such as a VPN, or the dark web) to mask their identities online, posing as criminals themselves. Likewise, covert world agencies can employ hacking techniques in the legal conduct of their work. On the other hand, hacking and cyber-attacks are used extra- and illegally by law enforceme ...

Electronics Companies Of The United Kingdom
The field of electronics is a branch of physics and electrical engineering that deals with the emission, behaviour and effects of electrons using electronic devices. Electronics uses active devices to control electron flow by amplification and rectification, which distinguishes it from classical electrical engineering, which only uses passive effects such as resistance, capacitance and inductance to control electric current flow. Electronics has hugely influenced the development of modern society. The central driving force behind the entire electronics industry is the semiconductor industry sector, which has annual sales of over $481 billion as of 2018. The largest industry sector is e-commerce, which generated over $29 trillion in 2017. History and development Electronics has hugely influenced the development of modern society. The identification of the electron in 1897, along with the subsequent invention of the vacuum tube which could amplify and rectify small elect ...

Sanyo
, stylized as SANYO, is a Japanese electronics company and formerly a member of the ''Fortune'' Global 500 whose headquarters was located in Moriguchi, Osaka prefecture, Japan. Sanyo had over 230 subsidiaries and affiliates, and was founded by Toshio Iue in 1947. On December 21, 2009, Panasonic completed a 400 billion yen ($4.5 billion) acquisition of a 50.2% stake in Sanyo, making Sanyo a subsidiary of Panasonic. In April 2011, Sanyo became a wholly owned subsidiary of Panasonic, with its assets integrated into the latter's portfolio. History Beginnings Sanyo was founded when Toshio Iue the brother-in-law of Konosuke Matsushita and also a former Matsushita employee, was lent an unused Matsushita plant in 1947 and used it to make bicycle generator lamps. Sanyo was incorporated in 1949; in 1952 it made Japan's first plastic radio and in 1954 Japan's first pulsator-type washing machine. The company's name means ''three oceans'' in Japanese, referring to the founder's ambiti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Badge Engineering
In the automotive industry, rebadging is a form of market segmentation used by automobile manufacturers around the world. To allow for product differentiation without designing or engineering a new model or brand (at high cost or risk), a manufacturer creates a distinct automobile by applying a new "badge" or trademark (brand, logo, or manufacturer's name/make/marque) to an existing product line. Rebadging is also known as '' rebranding'' and ''badge engineering''; the latter is an intentionally ironic misnomer, in that little or no actual engineering takes place. The term originated with the practice of replacing an automobile's emblems to create an ostensibly new model sold by a different maker. Changes may be confined to swapping badges and emblems, or may encompass minor styling differences, as with cosmetic changes to headlights, taillights, front and rear fascias and outer body skins. More extreme examples involve differing engines and drivetrains. The objective is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bandspread
In a radio receiver, a bandspread control is a secondary tuning control that allows accurate tuning of closely spaced frequencies of a radio band. With a main tuning control that covered a wide range of frequencies, for example 10-14 megahertz in a few turns of the tuning knob, a very small motion might change the tuning by tens of kilohertz and would make accurate tuning to any particular frequency difficult. A calibrated bandspread tuning control allows the main tuning to be set to a predefined spot on the control, and the bandspread allows tuning of a particular frequency within some restricted range of the main tuning control. One method of adding a bandspread control was to put a relatively small value variable tuning capacitor and dial directly in parallel with the main tuning variable capacitor ( or connected to a tap on the coil of the tuned circuit). The smaller capacitor would have much less effect on the resonant frequency than the main capacitor, allowing fine discrimina ...

D Battery
A D battery (D cell or IEC R20) is a standardized size of a dry cell. A D cell is cylindrical with an electrical contact at each end; the positive end has a nub or bump. D cells are typically used in high current drain applications, such as in large flashlights, radio receivers, and transmitters, and other devices that require an extended running time. A D cell may be either rechargeable or non-rechargeable. Its terminal voltage and capacity depend upon its cell chemistry. The National Carbon Company introduced the first D cell in 1898. Before smaller cells became more common, D cells were widely known as ''flashlight batteries.'' The U.S. military designation for this battery has been BA-30 since sometime before World War II. During World War II, it was designated the Type C battery by the U.S. Navy, leading to confusion with the smaller C cell battery (BA-42). In 2007, D batteries accounted for 8% of alkaline primary battery sales (numerically) in the US. In 2008, Swiss purc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tone Control Circuit
Tone control is a type of equalization used to make specific pitches or " frequencies" in an audio signal softer or louder. It allows a listener to adjust the tone of the sound produced by an audio system to their liking, for example to compensate for inadequate bass response of loudspeakers or earphones, tonal qualities of the room, or hearing impairment. A tone control circuit is an electronic circuit that consists of a network of filters which modify the signal before it is fed to speakers, headphones or recording devices by way of an amplifier. Tone controls are found on many sound systems: radios, portable music players, boomboxes, public address systems, and musical instrument amplifiers. Uses Tone control allows listeners to adjust sound to their liking. It also enables them to compensate for recording deficiencies, hearing impairments, room acoustics or shortcomings with playback equipment. For example, older people with hearing problems may want to increase the lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Integrated Circuit
An integrated circuit or monolithic integrated circuit (also referred to as an IC, a chip, or a microchip) is a set of electronic circuits on one small flat piece (or "chip") of semiconductor material, usually silicon. Large numbers of tiny MOSFETs (metal–oxide–semiconductor field-effect transistors) integrate into a small chip. This results in circuits that are orders of magnitude smaller, faster, and less expensive than those constructed of discrete electronic components. The IC's mass production capability, reliability, and building-block approach to integrated circuit design has ensured the rapid adoption of standardized ICs in place of designs using discrete transistors. ICs are now used in virtually all electronic equipment and have revolutionized the world of electronics. Computers, mobile phones and other home appliances are now inextricable parts of the structure of modern societies, made possible by the small size and low cost of ICs such as modern compute ...
