Pedal Powered Juicer Grinder

A juicer is a tool for separating juice from fruits, herbs, leafy greens and other types of vegetables from its pulp in a process called juicing. In separating the pulp, juicers concentrate the nutrition naturally present in fruits and vegetables and allows the body to more easily absorb the nutrition than digesting the solid produce. The use of juicers also makes it easier to consume more raw produce.

Electric Juicer is very common part of our life. But , do you know how much electricity we consume while juicing! if we start using pedal powered juicers,we will not only save large amount of electricity but our body would get some exercise too.

This project idea is for mechanical  and physics students.


Is it commercial viable?

Yes , it is , in New York I have seen it implemented where customer gets discount if he pedals his juice himself.

How to build my own?

Its simple, you need to buy some old juicer(I recommend sugar cane juicer for this project) and connect it with your bicycle instead of electric motor using belt. Video shown below will give you some idea about that.

Ruby on Rails Project

Ruby on Rails(ROR) was first introduced by David Hansson when he was working on the basecamp project. ROR is basically a framework developed on Ruby language. It makes website development interesting and very easy.

It works on two concepts -

1)Convention over configuration - Its a software design paradigm
to gain simplicity
2)Don't repeat yourself - Same code is not repeated twice anywhere in the program

Though the flexibility of programing is compromised but the programmer gets a speedy decision making advantage and also saves himself from future problems.

David Heinemeier Hansson extracted Ruby on Rails from his work on Basecamp, a project management tool by 37signals (now a web application company).Hansson first released Rails as open source in July 2004, but did not share commit rights to the project until February 2005.In August 2006, the framework reached a milestone when Apple announced that it would ship Ruby on Rails with Mac OS X v10.5 "Leopard",which was released in October 2007.


As many other frameworks, ruby on rails(ROR) also works on MVC(Model View Controller ) concept. There each layer is independent of the other. For eg. if you want to do something with application data, you code would be in the model layer which handles database. If the designer wants to implement new template he would have to work with view layer.

ROR is getting popular with each passing day. You can imagine the extend of its popularity only by the fact that Twitter and Groupon programming completely done on ROR only.

I am sharing some project ideas below which would help you to understand and learn about this extraordinary programming language which I personally use and recommend.

BCA Projects

BCA (Bachelor of Computer Application) is a undergraduate degree course in India.With the boom of the IT industry, it has become one of the most sought after graduate degree courses. Full-time BCA programmes normally take three academic years.The course usually consists of programming languages, mathematics, algorithms, data structures, networking, etc.Though , you can do project on any of the above topic,but still here I am suggesting project ideas related to programming languages.

C :

You can do project related to any topic related to computer science but I would personally recommend to go for C and C ++ Projects.

Advantage of using C: 

C is the base of computer programming and once you start understanding it , you will not face any difficulty in learning new languages. Other advantage with C is that it doesn't require large computer resources and you can run its project on any machine whether you are using windows or linux server.Not only that, because C is one of the oldest language , you will get lot of free resources and books of C on internet.

Once you start developing in C , you will also start understanding limitation of C language and get an idea why we had developed other programming languages.

C++ is for those students who wants to get exposure of object oriented programming. Developing project on C Plus Plus is great way to learn classes, object and constructors.

PHP:

It is one of the most popular language now-days.It is also known as Server Side Language. The reason behind its popularity is its simplicity. It can be written inside any html page and its embedded inside the page perfectly. It is really useful for designing dynamic website.It runs on Apache Server.

If any one of you are interested in web programming , you can build project on PHP.

Ruby on Rails:

ROR is a framework based on MVC(Model View Controller) developed in 2003 by David Heinemeier Hansson. It is based on ruby language .Rails provide us tools sufficient to build large websites such as Twitter.I am giving you few examples about sites which you can build using ROR below.

Job Recruitment System
Knowledge Sharing System
Purchase Order System

You can build anything using ROR which you build using Asp.net or PHP. So you can refer to theirs pages too for ideas related to its project.

Personal Finance Management

Personal finance refers to the financial decisions which an individual or a family unit is required to make to obtain, budget, save, and spend monetary resources over time, taking into account various financial risks and future life events.

Personal finance management is very important and useful in long term. Each individual should know about his or her spending habits as well as earning sources.

This project can be done by Computer Science , BCA , MCA and IT graduates.

Concept:

This application works as a small accounting software where we need to take input from the users, do some calculation inside and store these calculation and user input inside the database.

Procedure:

We need to design some forms to take input from the users. For ex. Form to take input of bills such as telephone, electricity or credit cards.

Once we take input, we will add all these values according to dates ( Weekly, Daily and Monthly Basis) and store them into our database.

We can add as many forms as user needs and store them accordingly. Sometime we need to use complex formula such as finding interest on amount or things like that , but that can be easily done using loops and variables.I am giving you some projects below from open source community which help you to understand this topic more.


Source Codes:
Java
Jgnash : jGnash is a cross platform personal finance application.It is a double entry system with support for multiple currencies.

PHP MySql
Personal Finance Manager: Multi-user Personal Finance Manager web application. It helps you to manage and reconcile accounts and transactions; track income and expenses.It uses Jquery based ajax form submission to eliminate page reloads.

Solar powered remote controlled aircraft

In  December 17, 1903  when Wright brothers build first aircraft,it became discovery, that changed the world completely.They build fixed wing aircraft which is capable of flight using wings that generate lift due to the vehicle's forward airspeed and the shape of the wings.In last century though, everything improved from design of aircraft, fuel efficiency and power of engine but aircraft fuel which is most important has not changed and become leading cause of global warming.

Why?
If you read airplane history, you would find that human need and desire of flying is more powerful than flying with renewable energy.So, focus in last century was only on designing and improving efficiency of engine and not on changing its fuel.

So , Why now?
In last decade, awareness of general public about climate change has increase significantly. With this awareness and fuel price that are rising at rocket speed creates catastrophic effect, which pressurizes us to think about alternate fuel for aircraft and one of these alternates is Solar Energy, which we are going to discuss today.

Is it possible?

Yes it is, recently Swiss made Solar Powered Plane, Solar Impulse completed its 4000 miles journey between Europe and Africa successfully. You can read more about it at news website msnbc.


What's the need of building solar powered RC planes?

When we think of building our plane, we know that because of financial and knowledge constraint we can only build models and small planes as our engineering project. We already discussed about RC planes in Aeronautical Projects Post . Solar Powered RC Plane is extension of that post.
Most of you know that planes are the biggest polluter of the world. In a series of steps we need to tackle global warming , solar rc planes could be vital.

Fabrication of Cam less engine

In this modern world where companies are focusing on green energy,cam less engine can become a great alternative.

A cam is a rotating or sliding piece in a mechanical linkage used especially in transforming rotary motion into linear motion or vice-versa. In an engine, it is connected to a shaft (e.g. a cylinder with an irregular shape) that strikes a lever at one or more points on its circular path.

In traditional engine camshaft has a very important role to play while opening and closing of a valve. It was a necessary evil for an engine functioning.Furthermore, because of camshaft, engineers need to choose either efficient engine or power engine but not with both qualities.This is one of the most important factor that makes camless engine a necessity. Though , idea of cam less engine existed from 1899,it has become need of modern world now, when we need power and efficiency both.
A camless engine uses electromagnetic, hydraulic, or pneumatic actuators to open the poppet valves instead. Actuators can be used to both open and close the valves, or an actuator opens the valve while a spring closes it.An actuator is a type of motor for moving or controlling a mechanism or system. It is operated by a source of energy, usually in the form of an electric current, hydraulic fluid pressure or pneumatic pressure, and converts that energy into some kind of motion.

Things required:
Mindstorm lego kit for Camless Engine

Advantages of using cam less engine:
Increase efficiency
Reduce emission
Improve Power

Disadvantage:
High power requirements of the actuator

Uses:
Camless IC Engines
Air Compressors

Water fuel Power Generation System

 Is it possible to use water to power our cars?

Some people claim that it is possible and done before and other thinks, it has never been done and would need more time before this actually happen. But all of them believe that someday we can run our cars on water. I found this project idea interesting enough to discuss with you. If you are believer of  water fuel cell invented by American Stanley Allen Meyer.Then you should try this project and see whether we can run our cars on water or if we can generate power using water fuel cells? 

I have never used water fuel cell myself and Stanley Meyer also lost his case in US Court when he found guilty of fraud.Still I want you to do some research on this topic because many people believes that Stanley finding were true and these fuel cells are going to be future and would solve our energy needs. 

Concept:
As we all know, opposite charges attract, so when we put anode and cathode into the H20, the positive charged hydrogen are attracted by cathode and negative charged oxygen is attracted by anode. Hence, HH and O bonds break to form HHO. This HHO can be supplied directly into Internal Combustion engines for moving the engine shaft.
This process can produce mechanical energy. Furthermore, this mechanical energy can be converted into electrical energy by using D.C generator. 30% of power from generator is consumed by electrolysis process and remaining 70% is for our applications.
