How voltage, current, and resistance relate : OHM's LAW An electric circuit is formed when a conductive path is created to allow free electrons to continuously move. This continuous movement of free electrons through the conductors of a circuit is called a current, and it is often referred to in terms of "flow," just like the flow of a liquid through a hollow pipe. The force motivating electrons to "flow" in a circuit is called voltage. Voltage is a specific measure of potential energy that is always relative between two points. Free electrons tend to move through conductors with some degree of friction, or opposition to motion. To be able to make meaningful statements about these quantities in circuits, we need to be able to describe their quantities in the same way that we might quantify mass, temperature, volume, length, or any other kind of physical quantity. The "symbol" given for each quantity is the standard alphabetical letter used to represent that quantity in an algebraic equation. What is the amount of current (I) in this circuit?

John Conway's Game of Life The Game The Game of Life is not your typical computer game. It is a 'cellular automaton', and was invented by Cambridge mathematician John Conway. This game became widely known when it was mentioned in an article published by Scientific American in 1970. playgameoflife.com New developments of this page will continue on playgameoflife.com. playgameoflife.com The Simulation Figure from the XKCD RIP John Conway comic. The Rules For a space that is 'populated': Each cell with one or no neighbors dies, as if by solitude. Each cell with four or more neighbors dies, as if by overpopulation. Each cell with two or three neighbors survives. For a space that is 'empty' or 'unpopulated' Each cell with three neighbors becomes populated. The Controls Choose a figure from the pull-down menu or make one yourself by clicking on the cells with a mouse. Development Game of Life is supported by Dotcom-Monitor, LoadView Testing, Web Hosting Buddy, Instructify, Security Guard Training Central, and Driven Coffee

Strain gauges : ELECTRICAL INSTRUMENTATION SIGNALS If a strip of conductive metal is stretched, it will become skinnier and longer, both changes resulting in an increase of electrical resistance end-to-end. Conversely, if a strip of conductive metal is placed under compressive force (without buckling), it will broaden and shorten. If these stresses are kept within the elastic limit of the metal strip (so that the strip does not permanently deform), the strip can be used as a measuring element for physical force, the amount of applied force inferred from measuring its resistance. Such a device is called a strain gauge. Strain gauges are frequently used in mechanical engineering research and development to measure the stresses generated by machinery. Aircraft component testing is one area of application, tiny strain-gauge strips glued to structural members, linkages, and any other critical component of an airframe to measure stress. A strain gauge's conductors are very thin: if made of round wire, about 1/1000 inch in diameter.

Main / Home Page Physical Computing is an approach to learning how humans communicate through computers that starts by considering how humans express themselves physically. In this course, we take the human body as a given, and attempt to design computing applications within the limits of its expression. If you're using the physical computing shop at ITP, welcome. This site is the info site for the shop and a portal for other resources. Shop Policies You Should Know All people using the shop must attend a safety seminar once a year and take the safety quiz in order to use the shop. All shop users are expected to follow the instructions of shop staff at all times. Confused as to when you're expected to do when it's your day to clean the shop?

NC Wind Energy - NC Wind Energy - Home Page Wiener While it is impossible to assign credit for the conception of Cybernetics to a single individual, certainly one of the people most responsible for its development and popularity as well as its theoretical shape was the mathematician Norbert Wiener (see Wiener, Norbert). Wiener wrote several popular books in which he coined the word "cybernetics," elaborated on its central concepts, and sought to illuminate its ethical and social implications. In so doing, he helped to spread the insights to be gained from studying control and communication systems, and also to heighten an awareness of the ethical and social consequences of automation and mass communication. As the son of one of the world's leading linguists, Wiener's etymology of "cybernetics" is itself instructive of his philosophy. Wiener did not coin the word until the summer of 1947, but he began the work leading up to the theory behind it in 1941, and published his theory in 1943. by Peter M. 1153 words For Further Research

Electronics Lab - Home Arduino - SmartSurfaces Arduino Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments. Arduino can sense the environment by receiving input from a variety of sensors and can affect its surroundings by controlling lights, motors, and other actuators. The microcontroller on the board is programmed using the Arduino programming language (based on Wiring) and the Arduino development environment (based on Processing). Why Arduino? There are many other microcontrollers and microcontroller platforms available for physical computing. Inexpensive - Arduino boards are relatively inexpensive compared to other microcontroller platforms. Cross-platform - The Arduino software runs on Windows, Macintosh OSX, and Linux operating systems. Open source and extensible hardware - The Arduino is based on Atmel's ATMEGA328 and ATMEGA168 microcontrollers. Links
