TechShop
TechShop was a chain of membership-based, open-access, do-it-yourself (DIY) workshops and fabrication studios. they had ten locations in the United States, as well as four international locations. TechShop offered safety and basic use training on all of its tools and equipment in addition to advanced and special interest classes and workshops. For most equipment, a safety and use class had to be completed before it could be used. It was affiliated with the maker culture and participated in annual Maker Faire events. On November 15, 2017, with no warning, the company closed all domestic locations and announced it would declare bankruptcy under Chapter 7 of the U.S. bankruptcy code (immediate liquidation). An effort to purchase the company's assets and reopen the workshops fell through; however, the San Francisco location was reopened by a new owner on February 19, 2018. The original TechShop filed for bankruptcy a few days later, on February 26, 2018. Due to the continuing cost ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

SawStop
SawStop is an American table saw manufacturer headquartered in Tualatin, Oregon. The company was founded in 2000 to manufacture table saws that feature a patented automatic braking system that stops the blade upon contact with skin or flesh. This aims to minimize injuries that are relatively common when working with normal table saws. How it works According to the manufacturer's website, the saw blade stops in less than five milliseconds, while angular momentum retracts the blade into the table. The operator suffers a minor injury instead of a serious one. The design takes advantage of the difference in conductance and capacitance between wood and flesh. An oscillator generates a 12-volt, 200-kilohertz (kHz) pulsed electrical signal, which is applied to a small plate on one side of the blade. The signal is transferred to the blade by capacitive coupling. A plate on the other side of the blade picks up the signal and sends it to a threshold detector. If a human contacts the ...

Maker Culture
The maker culture is a contemporary subculture representing a technology-based extension of DIY culture that intersects with hardware-oriented parts of hacker culture and revels in the creation of new devices as well as tinkering with existing ones. The maker culture in general supports open-source hardware. Typical interests enjoyed by the maker culture include engineering-oriented pursuits such as electronics, robotics, 3-D printing, and the use of computer numeric control tools, as well as more traditional activities such as metalworking, woodworking, and, mainly, its predecessor, traditional arts and crafts. The subculture stresses a cut-and-paste approach to standardized hobbyist technologies, and encourages cookbook re-use of designs published on websites and maker-oriented publications. There is a strong focus on using and learning practical skills and applying them to reference designs. There is also growing work on equity and the maker culture. Philosophical emphas ...

STEAM Fields
STEAM education is an approach to teaching STEM subjects that incorporates artistic skills like creative thinking and design. The name derives from the acronym ''STEM'', with an ''A'' added to stand for ''arts''. STEAM programs aim to teach students innovation, to critical thinking, think critically, and to use engineering or technology in imaginative designs or creative approaches to real-world problems while building on students' mathematics and science base. Education legislation for STEAM education in the U.S. Examples of state-based STEAM programs as guidance or related resources: * Ohio created the ''Quality Model for STEM and STEAM Schools''. By Ohio statute, a STEAM school is designated as a type of STEM school. * In May 2014, Rhode Island created the ''STEAM Now Coalition''. * In 2017, Nevada enacted legislation for the creation of a State Seal of STEM Program and a State Seal of STEAM Program. The STEAM seal is given to students who have "high level of proficiency in sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Laser Cutting
Laser cutting is a technology that uses a laser to vaporize materials, resulting in a cut edge. While typically used for industrial manufacturing applications, it is now used by schools, small businesses, architecture, and hobbyists. Laser cutting works by directing the output of a high-power laser most commonly through optics. The laser optics and CNC (computer numerical control) are used to direct the laser beam to the material. A commercial laser for cutting materials uses a motion control system to follow a CNC or G-code of the pattern to be cut onto the material. The focused laser beam is directed at the material, which then either melts, burns, vaporizes away, or is blown away by a jet of gas, leaving an edge with a high-quality surface finish. History In 1965, the first production laser cutting machine was used to drilling, drill holes in diamond Die (manufacturing), dies. This machine was made by the Western Electric Engineering Research Center. In 1967, the British pi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Oscilloscopes
An oscilloscope (formerly known as an oscillograph, informally scope or O-scope) is a type of electronic test instrument that graphically displays varying voltages of one or more signals as a function of time. Their main purpose is capturing information on electrical signals for debugging, analysis, or characterization. The displayed waveform can then be analyzed for properties such as amplitude, frequency, rise time, time interval, distortion, and others. Originally, calculation of these values required manually measuring the waveform against the scales built into the screen of the instrument. Modern digital instruments may calculate and display these properties directly. Oscilloscopes are used in the sciences, engineering, biomedical, automotive and the telecommunications industry. General-purpose instruments are used for maintenance of electronic equipment and laboratory work. Special-purpose oscilloscopes may be used to analyze an automotive ignition system or to display t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Abrasive Saw
__NOTOC__ An abrasive saw, also known as a cut-off saw or chop saw, is a circular saw (a kind of power tool) which is typically used to cut hard materials, such as metals, tile, and concrete. The cutting action is performed by an abrasive disc, similar to a thin grinding wheel. Technically speaking this is not a saw, as it does not use regularly shaped edges (teeth) for cutting. These saws are available in a number of configurations, including table top, free hand, and walk behind models. In the table top models, which are commonly used to cut tile and metal, the cutting wheel and motor are mounted on a pivoting arm attached to a fixed base plate. Table top saws are often electrically powered and generally have a built-in vise (tool), vise or other clamping arrangement. The free hand designs are typically used to cut concrete, asphalt, and pipe on construction sites. They are designed with the handles and motor near the operator, with the blade at the far end of the saw. F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Miter Saw
A miter saw or mitre saw is a saw used to make accurate crosscuts and miters in a workpiece by positioning a mounted blade onto a board. A miter saw in its earliest form was composed of a back saw in a miter box, but in modern implementation consists of a powered circular saw that can be positioned at a variety of angles and lowered onto a board positioned against a backstop called the fence. Powered miter saws also cut bevels into a work piece by adjusting the vertical tilt axis of upper portion of the machine while the table lays flat horizontally. A miter saw for which the axis can be tilted in a single direction is known as a single compound miter saw. If the axis can tilt both left and right, it is known as a double bevel compound miter saw. Some are equipped with a sliding rail system or have a pivot arm to cut wider work pieces when laid flat on the table of the saw and flush against the fence. This is known as a sliding compound miter saw. They are primarily used for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Table Saw
A table saw (also known as a sawbench or bench saw in England) is a woodworking tool, consisting of a circular saw blade, mounted on an mandrel, arbor, that is driven by an electric motor (directly, by belt, by cable, or by gears). The drive mechanism is mounted below a table that provides support for the material, usually wood, being cut, with the blade protruding up through the table into the material. In most modern table saws, the table is fixed and the blade position can be adjusted. Moving the blade up or down affects the depth of the cut by controlling how much of the blade is protruding above the table surface. Many saws also have an adjustable angle, where the blade can be tilted relative to the table. Some earlier saws instead had a fixed blade and the table could be adjusted for height (exposure of blade) and angle relative to the blade. Types The general types of table saws are compact, benchtop, jobsite, contractor, hybrid, cabinet, and sliding table saws. Bench ...
