• 09:59, 27 April 2024 Philip talk contribs created page Glossary:SIDAC (Created page with "A SIDAC or Silicon Diode for AC is a 2-terminal electronic component comprising 5 semiconductor layers which abruptly switches from a non-conducting to a conducting state when a certain voltage is applied, typically in the region of 150 - 300V depending on the type. It then remains conducting until the current falls below a small holding current. It is similar in operation to a DIAC except for the higher threshold voltage. It has a few niche applications...")

• 17:26, 23 April 2024 Philip talk contribs created page Glossary:RoHS (Created page with "The Restriction of Hazardous Substances or RoHS directive (sometimes known as the "lead-free directive") restricts the use of 10 hazardous substances in electrical and electronic equipment. These include lead, mercury, cadmium and hexavalent chromium, together with a further six organic chemicals. It took effect in the EU in 2006.")
• 17:15, 23 April 2024 Philip talk contribs created page Glossary:WEEE (Created page with "The Waste Electrical and Electronic Equipment or WEEE Directive obligates producers and distributors of electrical equipment placed on the market after 2005 to make provision for its end of life collection and recycling. It is applicable in the UK and the EU. It has been criticised for its disregard for reuse or repair as a means of reducing e-waste.")
• 17:02, 23 April 2024 Philip talk contribs created page Glossary:Soak test (Created page with "A soak test is an extended test of a device following manufacture or repair, with the aim of shaking out any manufacturing defects or shortcomings in the repair. Sometimes this will be performed at full power or in some other way designed to stress any weak components and precipitate any incipient failures.")
• 16:55, 23 April 2024 Philip talk contribs created page Glossary:Bathtub curve (Created page with "Reliability studies in many fields tend to show a common pattern for failures. Manufacturing defects are the principal cause of early life failures, but once these have all been shaken out the failure rate remains fairly low through the expected lifetime of a device. The failure rate then starts to climb as components begin to wear out. So plotting the failure rate against time gives a U-shaped curve, commonly known as the bathtub curve.")
• 15:29, 23 April 2024 Philip talk contribs created page Glossary:Conflict Materials (Created page with "Conflict materials are raw materials largely sourced from conflict regions, where their supply is likely to be used for the purchase of arms or the support of armed groups.")
• 15:26, 23 April 2024 Philip talk contribs created page Glossary:Critical Raw Materials (Created page with "CRM or Critical Raw Materials are those raw materials in critically short supply. This may be because there simply isn't much of them waiting to be mined, or because what there is is largely controlled by unfriendly or potentially hostile nations.")
• 15:20, 23 April 2024 Philip talk contribs created page Glossary:Upcycle (Created page with "Upcycling is the practice of taking disused or faulty items or their major components and reusing them in a different way, hence saving them from recycling or landfill.")
• 15:15, 23 April 2024 Philip talk contribs created page Glossary:Refurbishment (Created page with "Reurbishment is the practice of taking used items and giving them a new lease of life by replacing worn or damaged parts, bringing them up to date with a fresh software installation and perhaps replacing a slow hard drive with a much faster SSD.")
• 15:04, 23 April 2024 Philip talk contribs created page Glossary:Remanufacture (Created page with "Remanufacture is the practice of creating good-as-new products using some proportion of pre-used parts. Common examples are ink and toner cartridges and laptop batteries, could equally include a laptop given a new case, keyboard and battery.")
• 14:59, 23 April 2024 Philip talk contribs created page Glossary:Recycle (Created page with "Recycling is the practice of recovering raw materials from waste items. This is generally inefficient and often impracticable or uneconomic for valuable materials used in small quantities. Furtthermore the resultant raw materials may not be of sufficient quality for demanding applications. Hence it is regarded as the second-worst option, ahead only of landfill or incineration.")
• 14:50, 23 April 2024 Philip talk contribs created page Glossary:Circular economy (Created page with "A circular economy is one where a minimum of items or their parts are sent for landfill or incineration, and a high proportion are either reused, repaired or recycled, so minimising the consumption of raw materials and the pre-use carbon footprint.")
• 14:45, 23 April 2024 Philip talk contribs created page Glossary:Repair (Created page with "Repair is the second option (after reuse) in a circular economy. It has been shown that many devices sent for recycling could actually be repaired relatively easily and hence given a new lease of life.")
• 14:42, 23 April 2024 Philip talk contribs created page Glossary:Reuse (Created page with "Reuse is the preferred option in a circular economy. Many items are discarded because they have been replaced by a newer model, or simply fallen into disuse, but could be given a second life if sold or donated to a new owner.")
• 14:36, 23 April 2024 Philip talk contribs created page Glossary:E-Waste (Created page with "e-Waste is all those electrical and electronic goods discarded by their owner, whether because they are faulty, no longer needed, or simply replaced by a newer model.")
• 13:57, 23 April 2024 Philip talk contribs created page Glossary:Serialisation (Created page with "Serialisation is a name given to the practice of some manufacturers of assigning unique serial numbers to subsystems of a device such as a smart phone. A process only available to the manufacturer and authorised agents is then used to programme the serial numbers into the device and cause it to reject or limit the functionality of replacement parts such as screens or batteries.")
• 20:14, 20 April 2024 Philip talk contribs created page Glossary:Gallium (Created page with "Gallium is a soft metal similar to aluminium but with a low melting point. In electronics, many compounds of gallium are semiconductors with useful properties. Gallium arsenide devices are able to operate at much higher frequencies than their silicon counterparts and so are widely used in mobile phones and satellite comunications. Various other gallium compounds are used in practically all visible and infra-red LEDs.")
• 19:48, 20 April 2024 Philip talk contribs created page Glossary:Silicon Carbide (Created page with "Silicon carbide (as carborundum) has long been used as an abrasive, but it is also a semiconductor with useful properties for high power applications. In recent years silicon carbide devices such as MOSFETs having higher voltage and power ratings than equivalent silicon devices have been increasingly used in applications such as EVs and power conversion.")

• 17:12, 20 April 2024 Philip talk contribs created page Glossary:Simplex (Created page with "A simplex comminication channel is one that allows for commuication in one direction only, in conttrat to a duplex connection which supports 2-way communication.")
• 17:06, 20 April 2024 Philip talk contribs created page Glossary:COM port (Created page with "A COM port is a serial interface port using a DB-9 connector, offered by virtally all home and personal computers before the advent of USB. Modern computers often still offer simulated COM ports over USB connections for interfacing to simple devices requiring only to be able to exchange a stream of bytes.")
• 17:00, 20 April 2024 Philip talk contribs created page Glossary:D-sub (Created page with "D-subminiature connectors are a series of electrical connectors characterised by their D-shaped shell. Whilst there are numerous variants, just a few are or have been in common use. DB-9 (more correctly DE-9) and DB-25 were ubiqitus on home and personal computers as the serial (COM) and paralel ports before being displaced by USB, and DE-15 is still used for VGA video connectors.")
• 16:35, 20 April 2024 Philip talk contribs created page Glossary:DTE, DCE (Created page with "DTE or Data Terminal Equipment and DCE or Data Communications Equipment are the names given to the two ends of an RS-232 data connection.

• 16:24, 20 April 2024 Philip talk contribs created page Glossary:RS-232 (Created page with "RS-232 is an old standard originally conceived for communication between a modem and a computer or computer terminal, normally using DB-9 or DB-25 connectors. It was embodied in the COM ports that were once a feature of virtually all personal and home computers. Although now superseded by USB, due to its great simplicity and former ubiquity it is still used where low speed communication is r...")

• 08:08, 11 April 2024 Philip talk contribs created page Glosary:Reverse defenestration (Created page with "Reverse defenestration is a term used to describe the process of throwing Windows out of computers. This is generally in order to install Linux or some other non-Microsoft operating system instead. In partial reverse defenestration, a Windows istallation may remain in a dual-boot configuration or as a virtual machine but this is not admitted as true reverse defenesttration by purists, who prefer radical reverse defenestration, leaving behind...")

• 20:54, 30 March 2024 Philip talk contribs created page Glossary:Passkey (Created page with "Passkeys are a more secure and more convenient alternative to passwords for logging into a website. Your browser creates and stores a highly secure secret key and gives the website a corresponding public key. Using the public key and clever cryptographic magic, the website can subsequently prove that your bowser knows the secret key without your browser ever revealing what it is. A limitation is that you can only share passkeys between different platforms (Windows/Apple/...")
