Bicycle Sprayer

Pest Control is an important step for good agriculture production and we have already discussed about mechanical sprayer in this blog.To do our own pest and weed control, we don't need any exotic equipment, you just need an idea and some knowledge of science. Mansukhbhai Jagani of Gujarat (India) has both and he invented bicycle sprayer which is topic of our today's discussion.

As we have discussed in my last post, that in mechanical sprayer farmers need to pump manually, as a result, spraying remains difficult task with these sprayers. Today, we will discuss bicycle sprayer which is much easier to operate than its predecessor as it is powered by bicycle.

Hydraulic Clock

In the fast-moving world where new products launch every day, things look obscure and understanding technology behind it looks out of reach and complex.

Take an example of a digital clock, we all use them but never bothered about how they work and technology used in building them.

Today we are going to discuss a project which is not only interesting but has its own significance in a journey of innovations. It will help students learn the basics of hydraulics and fluid mechanics.

I have seen this project title at one education site and find it interesting enough to discuss it with you.

Candle Light Powered Fan

Candle light fan use technology which converts heat directly into electricity using a effect called Seebeck. The only problem with these fans is their efficiency which is lesser than 10 %. To use this technology we need thermoelectric materials such as Bismuth Telluride(Bi₂Te₃) or Lead Telluride (PbTe).

Mechanical engineering Project Ideas

In the field of mechanical engineering, we have a vast range of topics to select from. At present, companies and governments are dealing with two issues. First, is about global warming and the other is about competition.

For both these issues, mechanical engineers can contribute a lot. For example, to improve the competitiveness of the organization, you can build automation tools or robots which can help the company to improve its efficiency and similarly for global warming, you can bring some news ideas to either save energy or generate it without doing harm to nature.

The biggest positive about these is that solutions to both these issues are going to come from mechanical. This is the reason, I always recommend students to select topics which are related to either robotics or renewable energy.

I myself tried to find all the latest topics from around the world and write about them to give you some more insight into what's happening around.

Robotics 

Robotics Projects Robotics would be a good choice in mechanical projects: Robots are very attractive in comparison to other projects and if everything goes well they will make you win.

Though I  have written a separate post about robotics here as a starting point I would like to share all important links in this section. Using given links you can enhance your knowledge before building your own machines.

Mechanical Creeper for Disable Person

Working below the car is very common among the car mechanics and they do it with ease. Moreover, crawling under the car is very vital for their profession too. But, mechanics with disabilities due to old age or accident, found it difficult to work under it and in some cases, they might lose their jobs.

Thermal Engineering Projects

The projects of Thermal Engineering includes topics related to theory and applications of thermodynamics, fluid mechanics or heat, and mass transfers. The best example of this is Air conditioner. This is one of the most important branches of Mechanical engineering and we can not imagine even a single important task which can be done without using this branch of engineering in one or the other way.

Some project ideas related to this branch are :

Prediction of temperature and humidity distribution in a room with ceiling panel

CFD Modelling of coal combustion in drop tube reactor

Simulation of coal-air flow in a bowl type coal mill

Mathematical modeling of heat transfer in walking beam type reheat furnace

mini homemade wood lathe machine

A lathe is a machine tool which rotates the workpiece on its axis to perform various operations.
The wood lathe helps us to become creative. It can be used for a wide variety of very precise

operations that allow you to turn almost anything from a table leg, a chair leg, to a railing post, light
post or even a candle sconce. This machine allows you to hand cut the most amazing things out of
plain stock.

Materials Required :

1.Sewing Machine Motor
2.9/32 Socket
3.Epoxy
4.Hammer
5.Wood
6.Screw and Screwdriver
7.Drilling Machine.

Non Conventional Energy Projects

We have discussed many projects related to nonconventional energy and it is important that you select one of these as your final year or science fair project because concern over global warming is increasing with each passing day and solution of this problem can only be done by using science and engineering.

Automobile engineering project ideas

Automobile engineering is a very interesting field and its importance in our life is indisputable. Automobile engineering is a vast field and there are many different types of projects we can do. It ranges from petrol engines to diesel engines, diesel engines to hybrid engines and hybrid engines to completely green technologies. Moreover, as we all know that every new car has its own CPU and Memory and with having them into our cars, ideas are not in scarcity now. I myself got amazed by the new technology-driven innovation in the automobile industry where Tesla, Apple, and Google, all wants to become part of. Experts in the sector already start talking about the next competitors of GM and Ford, which is not going to be Toyota abut the technical companies I mentioned above. Moreover, with news of Lary Page's startup flying car is just around the corner, we can surely say that it is a very exciting time in the automobile industry.

Robotic arm with gripper

Robotic devices are used in all aspects of our world. We have seen robotic arms inside many factories working flawlessly but do you know, building a robotic arm is a challenging task. To make it works, it should perform several actions in particular order :

Civil engineering projects

The Petronas Twin Towers, designed by architect Cesar Pelli and Thornton-Tomasetti and Ranhill Bersekutu Sdn Bhd engineers, was the world's tallest buildings from 1998 to 2004.

What is Civil Engineering?

Civil engineering is one of the most ancient branches whose glimpse has been visible from 4000 BC in Egypt and Mesopotamia. It mainly deals with the design and construction of a structure such as a road, dam or building, etc. Though it is one of the most ancient science, civil engineers require a great amount of knowledge and planning before starting any new project. They need knowledge of building things in coastal areas, areas where Earthquakes are common and many more things. In this post, I am giving details of some projects which I find useful for students.

Mechanical Engineering Kinematics Project

In mechanical engineering, kinematics is a study of how object move. This object can be a car, a ball or a robot.

Solar Insect Robots: You can build an insect robot powered by solar as your project. It will help you to understand the concepts of both Robotics and Solar power.

How to build a Catapult?

Catapult is a device used to throw an object over a long distance. It has been used since ancient times, it has proven to be one of the most effective mechanisms during warfare. It was designed to break or circumvent city walls and other fortifications in siege warfare.

Cost: Around $ 10

Objective: 

We should build it in such a way that, it hits its target with accuracy with bare minimum cost.

Things to consider:

Holder
Base
Trigger Mechanism

In my opinion, for a holder, you can choose a hole which is smaller than the ball which you are going to throw out. The base should be as large as possible because we need maximum friction below the base and for the trigger, you can choose any elastic tube, I have read somewhere about medical tubing which is good too.

Design:

As shown above, catapult would be build using plywood. Two similar shape plywood will work as an arm and would give support to it. H Shape shown above is used as a holder stopper.

Maglev Train Project

If you have seen magnets in your life then you need no introduction regarding the power or force they have in themselves when they come in contact with either another magnet or iron. In this article, we will see how scientists had used this force in trains.
