Solid-state lighting (SSL) is a type of lighting that uses semiconductor light-emitting diodes (LEDs), organic light-emitting diodes (OLEDs), or polymer light-emitting diodes (PLEDs) as its source of light. SSL is different from traditional lighting because it does not use a filament or gas to create light. The main advantage of SSL over traditional lighting is … Read more
Polymer LEDs are light-emitting diodes (LEDs) that use a polymer (plastic) as their active material. They are a type of organic LED (OLED). Polymer LEDs are made by sandwiching a layer of light-emitting polymer between two electrodes, usually made of metal. When a voltage is applied to the electrodes, electrons are injected into the polymer … Read more
Thermal grease (thermal paste or thermal compound) is a type of thermal interface material (TIM) that is commonly used to fill the gaps between a heat sink and a CPU or GPU. Thermal grease is a thick, viscous material that helps to transfer heat away from these components and into the heat sink. It is … Read more
The 3270 Information Display System is a type of computer terminal that was popular in the 1970s and 1980s. It was used to access mainframe computers, and was designed to display text and graphics in a clear and concise manner. The 3270 was manufactured by IBM, and was one of the first terminals to offer … Read more
Circuit bending is the process of manipulating the circuitry of electronic devices to create new and unique sounds. It is often used with vintage or found electronic devices, such as toys, radios, and keyboards, but can also be used with more modern devices. Circuit bending generally involves opening up the device and soldering new connections … Read more

The Mac mini is notable for its small size, and for being the least expensive Mac computer available. Is Mac mini worth buying? Yes, the … Read more
The term “DB-xx” refers to a type of connector used for various purposes, including connecting computer peripherals and components. The number following “DB” indicates the number of pins or contacts on the connector. The most common types are DB-9 (9 pins), DB-15 (15 pins), DB-25 (25 pins), DB-50 (50 pins), and DB-68 (68 pins). These … Read more
A thin-film transistor (TFT) is a type of field-effect transistor (FET) made by depositing thin films of an active semiconductor layer as well as the dielectric and metallic gate electrode on a glass or plastic substrate. A typical TFT is composed of a glass substrate with an indium tin oxide (ITO) layer serving as the … Read more
A one-socket server is a server that only has one CPU socket. This means that there is only one CPU chip installed in the server, and that all of the server’s processing power comes from that one chip. One-socket servers are typically less expensive than multi-socket servers, but they are also less powerful. What is … Read more
The PLUGE pattern is a test pattern used to adjust the black level and contrast of a display device. The pattern consists of a series of black and white bars, with the black bars being of progressively darker shades. The white bars are used as a reference point, and the user adjusts the black level … Read more
