Lectron Microscope (EI)
Lectron was a modular electronic experimentation kit designed to introduce youth to basic electronic circuits and theory. Description The Lectron kit consisted of electronic components installed within individual "building blocks" with a clear plastic base, an opaque white top with the component's schematic symbol and permanent magnets attached to the leads of the enclosed components. Each building block was magnetically attached to a metal plate serving both as a work surface and ground (electrical), ground, eliminating the need for soldering, spring terminals or a breadboard. This gave the benefit of safety as well as the ability to rearrange the blocks to determine the effect on the circuit. The instruction manual gave instruction on the proper arrangement of the blocks as well as the function of each individual component's contribution to the final circuit. Experiments began with simple circuits such as a basic electric lamp circuit with switch and worked its way to a three ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Braun (company)
Braun GmbH ( "brown"; ) is a German consumer products company founded in 1921 and based in Kronberg im Taunus. The company is particularly well known for its industrial product design from the mid-20th century which included electric shavers and record players. From 1984 until 2007, Braun was a wholly owned subsidiary of The Gillette Company, which had purchased a controlling interest in the company in 1967. Braun is now a wholly owned subsidiary of Procter & Gamble, which acquired Gillette in 2005. History In 1921, (1890–1951), a mechanical engineer, established a small engineering shop in Frankfurt, Germany. In 1923, he began producing components for radio sets. By 1928, the company had grown to such an extent, partly due to the use of certain plastic materials, that it moved to new premises on ''Idsteiner Strasse''. In 1929, eight years after he started his shop, Max Braun began to manufacture entire radio sets. Soon after, Braun became one of Germany's leading radi ...

Educational Toys
Educational toys (sometimes also called "instructive toys") are objects of play, generally designed for children, which are expected to stimulate learning. They are often intended to meet an educational purpose such as helping a child develop a particular skill or teaching a child about a particular subject. They often simplify, miniaturize, or even model activities and objects used by adults. Although children are constantly interacting with and learning about the world, many of the objects they interact with and learn from are not toys. Toys are generally considered to be specifically built for children's use. A child might play with and learn from a rock or a stick, but it would not be considered an educational toy because 1) it is a natural object, not a designed one, and 2) it has no expected educational purpose. The difference lies in perception or reality of the toy's intention and value. An educational toy is expected to educate. It is expected to instruct, promot ...

Creative Playthings
Creative Playthings was an educational toy store and catalogue that was established by Frank and Theresa Caplan in 1945. The goal of Creative Playthings was to provide simple and beautifully designed toys to promote a child’s creativity and imagination. The original Creative Playthings store was located at 102 West 95th Street in New York City (which they eventually moved to Madison Avenue and 72nd Street). Initially, Frank Caplan made hardwood building blocks himself to sell in their store, often cutting and sanding the sets while parents waited in the shop. He then added animals, people, vehicles and other toys. Caplan believed that providing unpainted abstract forms that emphasized shape, color and texture, as opposed to lifelike details, would stimulate a child’s imagination. In collaboration with Martha New, Caplan also designed sets of large plain maple cubes that young children could rearrange into various forms and furniture. Known as "Hollow Blocks," these and other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pocket Calculator
An electronic calculator is typically a portable electronic device used to perform calculations, ranging from basic arithmetic to complex mathematics. The first solid-state electronic calculator was created in the early 1960s. Pocket-sized devices became available in the 1970s, especially after the Intel 4004, the first microprocessor, was developed by Intel for the Japanese calculator company Busicom. Modern electronic calculators vary from cheap, give-away, credit-card-sized models to sturdy desktop models with built-in printers. They became popular in the mid-1970s as the incorporation of integrated circuits reduced their size and cost. By the end of that decade, prices had dropped to the point where a basic calculator was affordable to most and they became common in schools. Computer operating systems as far back as early Unix have included interactive calculator programs such as dc and hoc, and interactive BASIC could be used to do calculations on most 1970s and 19 ...

Dieter Rams
Dieter Rams (born 20 May 1932) is a German industrial designer and retired academic who is closely associated with the consumer products company Braun, the furniture company Vitsœ, and the functionalist school of industrial design. His unobtrusive approach and belief in "less, but better" (german: Weniger, aber besser) design generated a timeless quality in his products which has influenced the practice of design as a whole and secured Rams worldwide recognition and appreciation. He is quoted as stating that: "Indifference towards people and the reality in which they live is actually the one and only cardinal sin in design." Life and career Dieter Rams began his studies in architecture and interior decoration at Wiesbaden School of Art in 1947, now part of the RheinMain University of Applied Sciences. A year later, in 1948, he took a break from studying to gain practical experience and finish his carpentry apprenticeship. He returned to the Wiesbaden School of Art in 1948 a ...

Egger-bahn
Egger-Bahn was a German model railway manufacturer. The company produced the first H0e ( HO (1:87) scale narrow gauge rolling stock using N gauge track) models, and established HOe as a viable model railway standard. The firm was founded in 1963 by three brothers. One of them, a performer, soon left the firm. Theodor Egger, technician, and Jonathan Egger, salesman, continued. The models first appeared at the 1963 Nuremberg Toy Fair. The scale/gauge combination represented 600–750 mm gauge lines, but could reasonably depict several similar narrow gauge sizes. 009 is a similar concept, used mainly for modelling UK-based prototypes, again on N gauge track, but to the OO scale of 4 mm to 1 ft (1:76.2). Egger was the first to produce H0e ready-to-run models, and they were a great success. In 1964 the range was expanded, including a steam locomotive. Models from Egger-Bahn were often used in presentation layouts. For instance Faller used them in their magazine, as the small ...

Schematic
A schematic, or schematic diagram, is a designed representation of the elements of a system using abstract, graphic symbols rather than realistic pictures. A schematic usually omits all details that are not relevant to the key information the schematic is intended to convey, and may include oversimplified elements in order to make this essential meaning easier to grasp, as well as additional organization of the information. For example, a subway map intended for passengers may represent a subway station with a dot. The dot is not intended to resemble the actual station at all but aims to give the viewer information without unnecessary visual clutter. A schematic diagram of a chemical process uses symbols in place of detailed representations of the vessels, piping, valves, pumps, and other equipment that compose the system, thus emphasizing the functions of the individual elements and the interconnections among them and suppresses their physical details. In an electronic circuit d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Model Train
Railway modelling (UK, Australia, New Zealand, and Ireland) or model railroading (US and Canada) is a hobby in which rail transport systems are modelled at a reduced scale. The scale models include locomotives, rolling stock, streetcars, tracks, signalling, cranes, and landscapes including: countryside, roads, bridges, buildings, vehicles, harbors, urban landscape, model figures, lights, and features such as rivers, hills, tunnels, and canyons. The earliest model railways were the 'carpet railways' in the 1840s. The first documented model railway was the Railway of the Prince Imperial (French: Chemin de fer du Prince impérial) built in 1859 by emperor Napoleon III for his then 3-year-old son, also Napoleon, in the grounds of the Château de Saint-Cloud in Paris. It was powered by clockwork and ran in a figure-of-eight. Electric trains appeared around the start of the 20th century, but these were crude likenesses. Model trains today are more realistic, in addition to bein ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
