Charging Dock-solaire quattro

Phone charging Dock system is one of the commonly used dock station in our homes. Smart phones and other accessories like smart watch….etc can be charged using dock station.

In this project, our aim is to design a new dock station by implementing additional features like bluetooth paring, Tele conference mode, Direct call mobile telephone…..An LCD display is provided for showing the details of Mobile phone or smart watch since it can be snyc with the dock station.

Our project focus on the charging method also since it has to be environmental friendly, safe and economic

Stirling Engine

The Stirling engine is a heat engine that is vastly different from the internal-combustion engine in your car. Invented by Robert Stirling in 1816, the Stirling engine has the potential to be much more efficient than a gasoline or diesel engine. But today, Stirling engines are used only in some very specialized applications, like in submarines or auxiliary power generators for yachts, where quiet operation is important. Although there hasn't been a successful mass-market application for the Stirling engine, some very high-power inventors are working on it.

A Stirling engine uses the Stirling cycle,­ which is unlike the cycles used in internal-combustion engines.

• The gasses used inside a Stirling engine never leave the engine. There are no exhaust valves that vent high-pressure gasses, as in a gasoline or diesel engine, and there are no explosions taking place. Because of this, Stirling engines are very quiet.
• The Stirling cycle uses an external heat source, which could be anything from gasoline to solar energy to the heat produced by decaying plants. No combustion takes place inside the cylinders of the engine.

There are hundreds of ways to put together a Stirling engine. In this article, we'll learn about the Stirling cycle and see how two different configurations of this engine work.

Paper Rullende Machine

The environmental impact of paper is significant, which has led to changes in industry and behavior at both business and personal levels. With the use of modern technology such as the printing press and the highly mechanized harvesting of wood, disposable paper has become a cheap commodity. This has led to a high level of consumption and waste. With the rise in environmental awareness due to the lobbying by environmental organizations and with increased government regulation there is now a trend towards sustainability in the industry. Paper recycling is the process of turning waste paper into new paper products. In this project, a paper rolling machine called “Paper Rullende machine “is created to recycle the waste paper to some extent. The Paper Rullende machine is an easy to use paper roller which compresses and rolls paper forming rigid rods. These can then be used to construct a wide variety of objects. This machine is designed to roll up newspaper very tightly to produce a rigid sticks, which have some similar property of wood and this sticks can be joined together using cable tie, wires…etc. and then it can be used in a variety of ways such as to create small sculptures, tables, chairs …etc that are used in our day to day life.

Low head centrifugal pump

        Day by day the cost of the energy increased due to the bulk utilization of machines. So we introduce a low cost low head centrifugal pump.

      The construction is simple and easy to transport. Pedal powered energy concept is not newer just removed in the modern time because once again there is need to shift towards is to protect the environment. The pedal operated pump can be constructed using local material and skill. This free the user from rising energy costs and can be used anywhere, producing pollution                                                                                       less environment.

Machine Design

Machines employ power to achieve desired forces and movement (motion). A machine has a power source and actuators that generate forces and movement, and a system of mechanisms that shape the actuator input to achieve a specific application of output forces and movement. Modern machines often include computers and sensors that monitor performance and plan movement, and are called mechanical systems.

Design is the creation of a plan or conventions for the construction of an object or a system (as in architectural blueprints, engineering drawings, business processes, circuit diagram and sewing patterns). Design has different connotations in different fields (see design disciplines below). In some cases the direct construction of an object (as in pottery, engineering, management, cowboy coding and graphic design) is also considered to be design.

Machine design is the process of engineering design. A machine is made up of mechanisms that work together to satisfy the requirements of what the machine needs to accomplish.
