"Propeller Clock" Mechanically Scanned LED Clock Seven light emitting diodes spin‚ giving the illusion of numbers in the air An Overview: Top View Side View How this clock works: A motor spins the "propeller"‚ and a small microprocessor keeps track of time and changes the pattern on seven LEDs with exact timing to simulate a 7 by 30 array of LEDs. It is an illusion‚ but it works nicely. To build this clock‚ few things are needed‚ including: 1. Skill with motors and mechanical

Leadership and Group Effectiveness The dynamics of group decision making is the central focus in the film 12 Angry Men. The leaders of the group are defined by two separate characteristics; those that are appointed as the leader and those with no special title that emerge as influential. In the movie you can recognize several concepts covered by Kinicki and Kreitner in their book Organizational Dynamics and Human Behavior (second edition). I will be discussing the concepts of task identity

The History of Clocks | |The history of clocks is very long‚ and there have been many different types of clocks over the centuries. Not all historians agree on the history of the clock. The word clock was first used in the 14th century (about 700 years ago). It comes from the word for bell in Latin ("clocca"). Using the Sun The first way that people could tell the time was by looking at the sun as it crossed the sky. When the sun was directly overhead in the sky‚ it was the middle of the day‚ or

‚‚4(y STRATEGY CLOCK Whereas Michael Porter’s generic approach to competitive advantage gives substantial prominence to low cost‚ Cliff Bowman’s’ Strategy Clock’ looks at generic competitive advantage from a purely market-based perspective (MBV). He argues that competitive advantage is of no value unless it is of value to the customer and that a customer will always have a preference for such products or services over those of competitors. This may seem obvious but managers do sometimes fail to

Leadership: In the movie 12 Angry Men there were two primary examples of leadership. The first was in the beginning of the movie‚ when the foreman gets everyone together in the room and has them sit down‚ assigning them each a number. He then proceeds to go over the process and rules they will proceed with‚ and sets up the initial voting. After the initial voting‚ he has them go around in a circle one by one to discuss the reasons why they voted the way they did. As the film progresses‚ the leadership

Reflection for path-goal Leadership Key behaviours among group members Most of us were participative and had a supportive leadership path‚ which means being more people-oriented. Differences among individual members 2 of us are task focused when it comes to leadership. One is directive and another is achievement-oriented. What results were surprising? What were possible causes of the differences? We had thought that our leadership styles would be the same. Giri and Santra (2010) found that

Many advanced high school and college chemistry students perform an experiment known as the "iodine-clock" reaction‚ in which hydrogen peroxide reacts with iodide to form iodine‚ and the iodine subsequently reacts with thiosulfate ion until the thiosulfate has been consumed. At that point‚ the reaction solutions turn blue in the presence of starch. The experiment helps students understand the fundamentals of chemical kinetics --- the speeds at which reactions take place. 1. Activation Energy

PROPELLER CLOCK OBJECTIVE :- In this project‚ our aim is to use PIC or 8051 microcontroller to control a row of LEDs to function it as a clock. ABSTRACT :- The Propeller Clock is an electronic device which has a series of LEDs on board that rotate with the help of a motor to give an illusion of a watching a clock ( Digital or Analogue ). This requires a DC motor which rotates the PCB connected to it with sufficient speed so as to create the illusion. The LEDs are connected to a microcontroller

The clock nowadays are technology that has been taken for granted. The focus of this case study is to show the importance of time measurement and how our life nowadays revolves around it. By going through history all the way from using the sun and stars to the development of clocks that neither lose nor gain one second in 200 million years to show how

The Twelve Principles of Spiritual Leadership Printed in Timeline (www.globalcommunity.org) by Will Keepin who is president of the Satyana Institute in Boulder‚ Colorado‚ a provisional set of "principles of spiritual leadership." These are neither definitive nor authoritative… but rather the beginning of a collective inquiry into how we can apply spiritual teachings in social change work. First: The first principle is that the motivation underlying our activism for social change must be transformed
