Circuit Board Repair and Rework Guide OutlineThe information within these guides should be helpful to anyone who works with bare circuit boards and circuit board assemblies. These guides are packed with illustrations and videos and follow popular IPC standards. These guides will help you through the maze of challenges you face when working on modern, high density circuit boards. If your company complies with ISO-9000 or any demanding quality standard, you can refer to these guides as your on-line reference. Guides in sections 1 through 6 detail the proper step-by-step techniques, tools and materials, and cautions needed to reliably repair and modify bare and assembled circuit boards.

Welcome to Stratech Systems Limited : FOD Detection System iFerretâ„¢ intelligent Airfield/Runway Surveillance and FOD (Foreign Object & Debris) Detection System Incidents arising from Foreign Objects & Debris (FOD) on runways cost the aviation industry US$4 billion in aircraft repairs and maintenance annually. Flight delays and accident claims add to the cost. FOD includes a wide range of materials, such as a part fallen off from an aircraft, a detached runway light fitting, building materials, rocks and even wildlife. The Air France Concorde crash in July 2000, which claimed 113 lives, reinforces the need for real-time, automated FOD detection. HyperPhysics Concepts About HyperPhysics Rationale for Development HyperPhysics is an exploration environment for concepts in physics which employs concept maps and other linking strategies to facilitate smooth navigation. For the most part, it is laid out in small segments or "cards", true to its original development in HyperCard.

Temperature-controlled Fan - circuit diagrams, schematics, electronic projects Warning! The circuit is connected to 230Vac mains, then some parts in the circuit board are subjected to lethal potential! Avoid touching the circuit when plugged and enclose it in a plastic box. Gradually increases speed as temperature increases Widely adjustable temperature range Fowler's Physics Applets This applet is a slightly simplified representation of Ptolemy's mode for the motion of the inner planets. From our modern perspective, the planets do not go in perfect circles around the Sun. If they did, our simplified Ptolemy model of uniform circular motion around an epicycle which is itself precessing uniformly would represent exactly the motion of the planet through the heavens. In fact, this is very close to the truth: the true orbits are ellipses, but very close to circular. Ptolemy's model had to be refined with small extra epicycles, or not quite uniform circular motion. Here we just want to emphasize the main point: how this simple model can successfully account for the motion of the planets in the heavens to a very good approximation, but keeps the Earth itself at rest.

PIC programming This PIC C programming tutorial will guide you to get a simple C program working on a PIC microcontroller, including setup of the programmer. The tutorial uses C programming with the Microchip C18 compiler, and the relatively newer PIC18F1320 chip. That chip has analog-to-digital converters, serial communications ability, and other nice peripherals. If you haven't used microcontrollers before, they're a great way to add intelligence to your projects. They're just tiny, cheap computers. 15 Ways to Hack Your Brain For A Better Life ...For answer Holmes clapped the hat upon his head. It came right over the forehead and settled upon the bridge of his nose. "It is a question of cubic capacity, " said he; "a man with so large a brain must have something in it. " ...

Michael Frayn's "Copenhagen" Copenhagen is a play about two men in a complex relationship who come together in the afterlife to understand their friendship and its strains. Science brought them together; they felt like father and son or director and boy Friday. Politics divided them, yet as they talk about their past, other tensions, such as competitiveness, come to the fore. Another person is present and offers her insights into their affinities and variances. Their encounter is human: full of memories and memory lapses, as well as affection and denial.
