Point-to-point construction uses terminal strips(sometimes know as 'tag boards'). A terminal strip is a stamped strip of tin-plated loops of copper. It is mounted in a way that electrically insulates it. Usually it is mounted on a cheap, heat-resistant material, usually brown bakelite or paxolin, or perhaps epoxy-resin bonded paper (ERBP). This material is mounted on a metal standoff with a mounting hole. The chassis was constructed first, from sheet metal or wood. Insulated terminal strips were then riveted, nailed or screwed ...

In CNC manufacturing the CAM system is used to simplify the machining and design process. In most cases the CAM system will work with a CAD design made in a 3D environment. The CNC programmer will just specify the machining operations and the CAM system will create the CNC program. This compatibility of CAD/CAM systems eliminates the need for redefining the work piece configuration to the CAM system. In other words: C.A.M. is a software usually comes with a machine such as a lathe or miller which is controlled by the software. The entire system tends to be extremely expensive (a lathe a ...

An autopilot is a mechanical, electrical, or hydraulic system used to guide a vehicle without assistance from a human being. Most people understand an autopilot to refer specifically to aircraft, but autopilots for boats and ships are called by the same name and serve the same purpose. In the early days of transport aircraft, aircraft required the continuous attention of a pilot in order to fly in a safe manner. This created very high demands on crew attention and high fatigue. The autopilot is des ...

A USB flash drive is essentially NAND-type flash memory integrated with a USB 1.1 or 2.0 interface used as a small, lightweight, removable data storage device of up to 8 GB (as of 2006). Depending on the drive type and OS version, and in some cases what patches are installed, the drives generally work with Windows 98/ME/2000/XP (Windows 98 requires a driver to be installed; often, inconveniently, a specific driver for each type of flash drive), Macintosh, ...

A DIP switch is an electric switch that is packaged in a standard dual in-line package (DIP). Because of the DIP form factor, arrays of multiple switches can easily be incorporated into the same package. This type of switch is designed to be used on a printed circuit board along with other electronic components and is commonly used to customize the behavior of an electronic device for specific situations. These were extensively used in older ISA PC cards to select IRQ's and memory addresses. DIP switches are often used instead of jumper bloc ...

CC1(C)OOC(C)(C)OO1 Acetone peroxide (triacetone triperoxide, peroxyacetone, TATP, TCAP) is an organic peroxide and a primary high explosive. It takes the form of a white crystalline powder with a distinctive acrid smell. It is highly heat, friction, and shock sensitive. For its instability, it has been called the "Mother of Satan". Acetone peroxide was discovered in 1895 by R. Wolffenstein (Chemische Berichte 28, 2265 (1895)). Infor ...

The mechanics behind a PCB milling machine are fairly straightforward and have their roots in CNC milling technology. A PCB milling system is similar to a miniature and highly accurate NC Milling table. For machine control, positioning information and machine control commands are sent from the controlling software via a serial port or parallel port connection to the milling machine's on-board controller. The controller is then responsible for driving and monitoring the various positioning components which move the milling head and gantry and ...

While a capacitor resists changes in voltage, an inductor resists changes in current. An ideal inductor would offer no resistance to direct current, however, all real-world inductors have non-zero electrical resistance. In general, the relationship between the time-varying voltage v(t) across an inductor with inductance L and the time-varying current i(t) passing through it is described b ...

Magnetic core - Straight cylindrical rod. Most commonly used in radios especially for tuning an inductor. The rod sits in the middle of the coil and small adjustments of the rod position will fine tune the inductance. Often the rod is threaded to allow adjustment with a screwdriver. In radio circuits, a dob of wax or resin is used once the inductor has been tuned to prevent the core from moving. The presence of the high permeability core increases the inductance but the field must still spread into the air ...

MOS Technology's first processor, the 6501, could be plugged into existing motherboards that used the Motorola 6800, allowing potential users (i.e. engineers and hobbyists) to get a development system up and running very easily using existing hardware. This enraged Motorola, who immediately sued, forcing MOS to pull the 6501 from the market. Changing the pin layout produced the "lawsuit-friendly" 6502. Otherwise identical to the 6501, it nevertheless had the disadvantage of having no machine in which new users could quickly start playing wit ...

Flash drives are impervious to the scratches and dust that plagued previous forms of portable storage like compact discs and floppy disks, and their durable solid-state design means they often survive casual abuse (impacts, being dropped or crushed, run through a washing machine, or even dropped in coffee). This makes them ideal for transporting personal data or work files from one location to another (such as from home to school or office) or for carrying around personal data that the user typically wants to access in a variety of places.

A JTAG interface is a special four/five-pin interface added to a chip, designed so that multiple chips on a board can have their JTAG lines daisy-chained together, and a test probe need only connect to a single "JTAG port" to have access to all chips on a circuit board. The connector pins are TDI (Test Data In) TDO (Test Data Out) TCK (Test Clock) TMS (Test Mode ...

Soldering to gold-plated parts can be tricky. Gold dissolves in solder; an alloy of solder which contains more than 5% of gold can become brittle and the joint surface is dull-looking. If the gold layer does not completely dissolve in the solder, it may be pulled off the underlying surface later as the tin and gold atoms cross-migrate and undergo Kirkendall voiding, leading into a mechanical failure of the joint; a similar process on the gold-aluminum interface is known as purple plague. Thin layers of gold (under 20 mil) dissolve in the solder, exposing the ...

The basis of the fourth generation was Marcian Hoff's invention of the microprocessor. Unlike Third generation minicomputers, which were essentially scaled down versions of mainframe computers, the fourth generation's origins are fundamentally different. Microprocessor based computers were originally very limited in their computational ability and speed, and were in no way an attempt to downsize the minicomputer. They were addressing an entirely different market. Although processing power and storage capacities have increased b ...
