Electronic Waste
Electronic waste (or e-waste) describes discarded electrical or electronics, electronic devices. It is also commonly known as waste electrical and electronic equipment (WEEE) or end-of-life (EOL) electronics. Used electronics which are destined for refurbishment, reuse, resale, salvage recycling through material recovery, or disposal are also considered e-waste. Informal processing of e-waste in developing country, developing countries can lead to adverse effect, adverse human health effects and environmental pollution. The growing consumption of electronic goods due to the Digital Revolution and innovations in science and technology studies, science and technology, such as bitcoin, has led to a global e-waste problem and hazard. The rapid exponential increase of e-waste is due to frequent new model releases and unnecessary purchases of electrical and electronic equipment (EEE), short innovation cycles and low recycling rates, and a drop in the average life span of computers.

Cathode Ray Tube
A cathode-ray tube (CRT) is a vacuum tube containing one or more electron guns, which emit electron beams that are manipulated to display images on a phosphorescent screen. The images may represent electrical waveforms on an oscilloscope, a Film frame, frame of video on an Analog television, analog television set (TV), Digital imaging, digital raster graphics on a computer monitor, or other phenomena like radar targets. A CRT in a TV is commonly called a picture tube. CRTs have also been Williams tube, used as memory devices, in which case the screen is not intended to be visible to an observer. The term ''cathode ray'' was used to describe electron beams when they were first discovered, before it was understood that what was emitted from the cathode was a beam of electrons. In CRT TVs and computer monitors, the entire front area of the tube is scanned repeatedly and systematically in a fixed pattern called a raster scan, raster. In color devices, an image is produced by con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heavy Metals
upright=1.2, Crystals of lead.html" ;"title="osmium, a heavy metal nearly twice as dense as lead">osmium, a heavy metal nearly twice as dense as lead Heavy metals is a controversial and ambiguous term for metallic elements with relatively high density, densities, atomic weights, or atomic numbers. The criteria used, and whether metalloids are included, vary depending on the author and context and it has been argued that the term "heavy metal" should be avoided. A heavy metal may be defined on the basis of density, atomic number or chemical behaviour. More specific definitions have been published, none of which have been widely accepted. The definitions surveyed in this article encompass up to 96 out of the 118 known chemical elements; only mercury, lead and bismuth meet all of them. Despite this lack of agreement, the term (plural or singular) is widely used in science. A density of more than 5 g/cm3 is sometimes quoted as a commonly used criterion and is used in the b ...

Phonebloks
Phonebloks is a modular smartphone concept created and designed by the Dutch designer Dave Hakkens in 2013, primarily to reduce electronic waste. While Phonebloks is not the first attempt at modular design in a phone, it is notable due to the extent of its modularity and the attention and support it has gained. By attaching individual third-party components (called "bloks") to a main board, a user would create a personalized smartphone. These bloks can be replaced at will to replace a broken blok, to upgrade an existing blok, or to expand the functionality of the phone into a specific direction. Bloks would be available in Blokstore, "an app store for hardware", where users could buy new and used bloks as well as sell back their old ones. There is no plan to actually produce the Phonebloks design as a commercial product. Concept Hakkens graduated cum laude from the Design Academy Eindhoven in summer 2013 with his idea for Phonebloks. Phonebloks consists of a main board o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Modular Smartphone
A modular smartphone is a smartphone designed for users to upgrade or replace components and modules without the need for resoldering or repair services. The most important component is the main board, to which others such as cameras and batteries are attached. Components can be obtained from open-source hardware stores. This design aims to reduce electronic waste, increase the phone's lifespan, and lower repair costs. However, modular smartphones are generally bulkier and slower than their non-modular counterparts which may make them less attractive for most consumers. Motivation Environmental impact and ethical considerations Consumers may be motivated to buy modular phones to bypass non-modular phones, which are designed with planned obsolescence. Planned obsolescence, originating from American industrial designer Brooks Stevens, is a strategy of selling phones to be replaced rather than repaired. Planned obsolescence in smartphones prematurely shortens their life span ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Planned Obsolescence
In economics and industrial design, planned obsolescence (also called built-in obsolescence or premature obsolescence) is the concept of policies planning or designing a good (economics), product with an artificially limited Product lifetime, useful life or a purposely frail design, so that it becomes obsolete after a certain predetermined period of time upon which it decrementally functions or suddenly ceases to function, or might be perceived as fashion, unfashionable. The rationale behind this strategy is to generate long-term sales volume by reducing the time between repeat purchases (referred to as "shortening the replacement cycle"). It is the deliberate shortening of the lifespan of a product to force people to purchase functional replacements. Planned obsolescence tends to work best when a producer has at least an oligopoly. Before introducing a planned obsolescence, the producer has to know that the customer is at least somewhat likely to buy a replacement from them in ...

Random-access Memory
Random-access memory (RAM; ) is a form of Computer memory, electronic computer memory that can be read and changed in any order, typically used to store working Data (computing), data and machine code. A random-access memory device allows data items to be read (computer), read or written in almost the same amount of time irrespective of the physical location of data inside the memory, in contrast with other direct-access data storage media (such as hard disks and Magnetic tape data storage, magnetic tape), where the time required to read and write data items varies significantly depending on their physical locations on the recording medium, due to mechanical limitations such as media rotation speeds and arm movement. In today's technology, random-access memory takes the form of integrated circuit (IC) chips with MOSFET, MOS (metal–oxide–semiconductor) Memory cell (computing), memory cells. RAM is normally associated with Volatile memory, volatile types of memory where s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
