Lego Mindstorms
Lego Mindstorms (sometimes stylized as ''LEGO MINDSTORMS'') is a discontinued line of educational kits for building programmable robots based on Lego bricks. It was introduced on 1 September 1998 and discontinued on 31 December 2022. Mindstorms kits allow users to build creations that interact with the physical world. All Mindstorms kits consist of a selection of Lego Elements, a "Smart Brick" (internally known as a programmable brick or "pbrick"), which serves as the "brain" for a Mindstorms machine. Each set also includes a few attachments for the smart brick (such as motors and sensors) and programming software. Unlike conventional Lego sets, Mindstorms kits do not have a main model to build. Sample builds are included with each version of Mindstorms, but the kit is open-ended with the intent of the user creating and programming their own designs. In addition to at-home use, Mindstorms products are popularly used in schools and in robotics competitions such as the FIRST Leg ...

Robotics
Robotics is the interdisciplinary study and practice of the design, construction, operation, and use of robots. Within mechanical engineering, robotics is the design and construction of the physical structures of robots, while in computer science, robotics focuses on robotic automation algorithms. Other disciplines contributing to robotics include electrical engineering, electrical, control engineering, control, software engineering, software, Information engineering (field), information, electronics, electronic, telecommunications engineering, telecommunication, computer engineering, computer, mechatronic, and materials engineering, materials engineering. The goal of most robotics is to design machines that can help and assist humans. Many robots are built to do jobs that are hazardous to people, such as finding survivors in unstable ruins, and exploring space, mines and shipwrecks. Others replace people in jobs that are boring, repetitive, or unpleasant, such as cleaning, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CompUSA
CompUSA, Inc. was a retailer and reseller of Personal computer, personal computers, consumer electronics, technology products and computer services. Starting with one Brick and mortar, brick-and-mortar store in 1986 under the name Soft Warehouse, by the 1990s CompUSA had grown into a nationwide big-box store, big box chain. At its peak, it operated at least 229 locations. Crushed by competition from other brick-and-mortar retailers, corporate oversight which was out of touch with evolving market realities, and a failure to make a strong transition to online sales, CompUSA began closing what they classified as "low performing" locations in 2006. By 2008 only 16 locations were left to be sold to Systemax. In 2012, remaining CompUSA and Circuit City stores were converted to TigerDirect stores, and later closed. As of 2023, the CompUSA online website redirects to an error page. History Founded in 1984 as Soft Warehouse in Addison, Texas, a northern suburb of Dallas, Texas, by Errol ...

Digital Command Control
Digital Command Control (DCC) is a standard for a system for the digital operation of model railways that permits locomotives on the same electrical section of track to be independently controlled. The DCC protocol is defined by the Digital Command Control Working group of the US National Model Railroad Association (NMRA), which owns the trademark for the DCC logo. History A digital command control system was developed (under contract by Lenz Elektronik GmbH of Germany) in the 1980s for two German model railway manufacturers, Märklin and Arnold. The first digital decoders that Lenz produced appeared on the market early 1989 for Arnold ( N scale) and mid 1990 for Märklin ( Z scale, H0 scale and 1 gauge; Digital=). Märklin and Arnold exited the agreement over patent issues, but Lenz continued to develop the system. In 1992 Stan Ames, who later chaired the NMRA/DCC Working Group, investigated the Märklin/Lenz system as possible candidate for the NMRA/DCC standards. When the N ...

Lego Train
Lego (, ; ; stylised as LEGO) is a line of plastic construction toys manufactured by the Lego Group, a privately held company based in Billund, Denmark. Lego consists of variously coloured interlocking plastic bricks made of acrylonitrile butadiene styrene (ABS) that accompany an array of gears, figurines called minifigures, and various other parts. Its pieces can be assembled and connected in many ways to construct objects, including vehicles, buildings, and working robots. Assembled Lego models can be taken apart, and their pieces can be reused to create new constructions. The Lego Group began manufacturing the interlocking toy bricks in 1949. Moulding is done in Denmark, Hungary, Mexico, and China. Brick decorations and packaging are done at plants in the former three countries and in the Czech Republic. Annual production of the bricks averages approximately 36 billion, or about 1140 elements per second. One of Europe's biggest companies, Lego is the largest toy man ...

Infrared
Infrared (IR; sometimes called infrared light) is electromagnetic radiation (EMR) with wavelengths longer than that of visible light but shorter than microwaves. The infrared spectral band begins with the waves that are just longer than those of red light (the longest waves in the visible spectrum), so IR is invisible to the human eye. IR is generally (according to ISO, CIE) understood to include wavelengths from around to . IR is commonly divided between longer-wavelength thermal IR, emitted from terrestrial sources, and shorter-wavelength IR or near-IR, part of the solar spectrum. Longer IR wavelengths (30–100 μm) are sometimes included as part of the terahertz radiation band. Almost all black-body radiation from objects near room temperature is in the IR band. As a form of EMR, IR carries energy and momentum, exerts radiation pressure, and has properties corresponding to both those of a wave and of a particle, the photon. It was long known that fires e ...

Upload
Uploading refers to ''transmitting'' data from one computer system to another through means of a network. Common methods of uploading include: uploading via web browsers, FTP clients, and terminals ( SCP/ SFTP). Uploading can be used in the context of (potentially many) clients that send files to a central server. While uploading can also be defined in the context of sending files between distributed clients, such as with a peer-to-peer (P2P) file-sharing protocol like BitTorrent, the term file sharing is more often used in this case. Moving files within a computer system, as opposed to over a network, is called file copying. Uploading directly contrasts with downloading, where data is ''received'' over a network. In the case of users uploading files over the internet, uploading is often slower than downloading as many internet service providers (ISPs) offer asymmetric connections, which offer more network bandwidth for downloading than uploading.

Microcontroller
A microcontroller (MC, uC, or μC) or microcontroller unit (MCU) is a small computer on a single integrated circuit. A microcontroller contains one or more CPUs (processor cores) along with memory and programmable input/output peripherals. Program memory in the form of NOR flash, OTP ROM, or ferroelectric RAM is also often included on the chip, as well as a small amount of RAM. Microcontrollers are designed for embedded applications, in contrast to the microprocessors used in personal computers or other general-purpose applications consisting of various discrete chips. In modern terminology, a microcontroller is similar to, but less sophisticated than, a system on a chip (SoC). A SoC may include a microcontroller as one of its components but usually integrates it with advanced peripherals like a graphics processing unit (GPU), a Wi-Fi module, or one or more coprocessors. Microcontrollers are used in automatically controlled products and devices, such as automobile engi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hitachi H8
The Hitachi H8 is a large family of 8-bit, 16-bit and 32-bit microcontrollers made by Renesas Technology, originating in the early 1990s within Hitachi Semiconductor. The original design, the H8/300, was an 8-bit processor that had a 16-bit registers and ALU that allowed some 16-bit operations. Two upgraded versions were introduced, the H8/300L that expanded the instructions to become a full 16-bit machine while being optimized for low cost, and the H8/300H which further expanded the registers to allow 32-bit operations and was optimized for low-power/high-performance roles. Many variations exist. The entire line was sold to Renesas in 2003. Renesas continues to sell the designs , but only to existing customers. An administrator on the Renesas user community boards commented in 2011 that there are no plans for further development of H8 based products. H8 was supported in the Linux kernel starting with version 4.2 but support was removed in version 5.19. For higher performanc ...
