Build your own Wind Turbine

 A wind turbine is a device that converts kinetic energy from the wind into mechanical energy. This turbine can be used for many purposes such as producing electricity, grinding grain or pumping water.

In this project, we are talking about how we can use it to produce electricity.

Pedal Powered Washing Machine

A washing machine is a machine designed to wash laundry, such as clothing, towels, and sheets. Generally, these machines have been powered by electrical energy but pedal-powered machine runs with our energy.

Pedal-powered washing machines can be very useful for rural places in developing countries where electricity is out of reach. Moreover, in developed countries too, it can be used to save electricity and getting some workout.

Talking Robots with Lego Mindstorms

From the days of the "Small Wonder" TV show, I always wanted to have one robot which can talk and respond just like a human. To build one as a Robotic Project is really interesting. This project is going to be very interesting and challenging because our robot requires not only to speak capability but should have artificial intelligence to learn from its surroundings.

Architecture for talking robots consists of four main modules:

• Dialogue system
• Speech client with speech recognition and synthesis capabilities
• Module for infrared communication between the PC and the RCX and
• the program that runs on the RCX itself.

NXT Sensors

Hardware Requirement :

Lego Mindstorms NXT 2.0 which includes :

• Ultrasonic sensor 
• Touch sensors: Lets the robot react to touch
• Servo motors: Allows the robot to interact with the environment
  NXT Brick: The programmable core that reads the sensors and controls the motors and things many more. You can buy it from any online store including amazon.com

Software Requirement :

NXT-G:  is a graphical programming environment that comes bundled with the NXT. With careful construction of MyBlocks to encapsulate complexity, NXT-G can be used for real-world programming.

Business projects

Thinking of starting a new venture and don't know how? This same problem has been faced by many of us. Starting a business looks difficult initially but it is not rocket science. Fundamentals of business have not changed from centuries. Even though we are living in a technology world and sometimes feel that we need to think out of the box for running a successful business, but in real life, we do not. In this post, we will discuss some really good ideas. Remember, starting a business is not a big deal but running it successfully requires dedication and determination.

There are a lot of businesses you can do but I will suggest ideas that can be implemented with minimum or no costing at all. Look around and pick something you are passionate about:

Part-Time Work having Potential to become full time :

1.Start a blog: This doesn't look like a business, but it is a really good option with no investment.Wanna write one, start with blogger.com

2. Write a book: Yes, you don't need to be perfect for writing a book. Just start doing it write one page a day. Its really fun and you will able to complete at least 200 pages at the end of a year.

3.Education Consultant: Do research about education environment, colleges, admission procedure and stuff like that and provide paid consultancy for that.

4.Property Dealer: Help sellers and buyers to get the right kind of property and get a hefty commission for that.

Businesses with Investment  :

Event Management Company: You can start your own event management company, which organizes events such as marriages in your city. Hire some quality people from this field, they bring experience as well as contacts for you.

Distribution ship:  Get a distribution ship of any reputed company with minimum presence in your city. If its possible find some new companies in the market whom you believe to get bigger by time. The advantage of associating with a new company is that you will get a good share in profit with the minimum competition including help from the companies administration.

Auction Website like eBay:  You can start your own auction site like eBay.With the open-source community around it doesn't cost much, just download auction site code from sites like Sourceforge.
 
Restaurant:  If you love cooking and have something special in that, you can start your own restaurant. For a start, you can serve only selected dishes and as word of mouth spread you can add more food items later.

Fruit and Vegetable: This business requires a big chunk of land and time. Grow fruits or vegetables with a working partnership with experienced local farmers. Use the best technology available to make this business profitable such as Sprinklers, Drip Irrigation or Bird Scarer.

The business of Finance: This requires a lot of money but you can arrange it with a profit-sharing basis with the moneylender. To run this business successfully you can ask your customer for some security like gold.

Packers and Movers: People often face difficulty to shift there offices or homes from one place to another. You can become there helping hand.

Importer: If you have a good market sense, you can import cheap foreign goods from developing countries like China and sell them to the shopkeepers.

Tricycle powered by pedals and electricity

An electric tricycle is a bicycle having three wheels with an electric motor used to power the vehicle. The tricycle which is powered by electricity would be very helpful for people who use cycles in there daily life. It would not only increase the speed of the cycle but also helps them in paddling.

PLC automatic Bottle Filling Machine

The importance of Bottle filling is realized by us when we see how many bottles we use in our daily life. Bottles are everywhere from cold drinks to beer, toilet cleaner to medicine,  etc. This bottle is filled with the help of a filling machine without which it would have a very difficult task. This project is about these machines.

Can Crusher Experiment

Can crushing is very important to reuse aluminum in these cans. Moreover, this contributes to significantly lower the waste management problem. These can crusher can be made to work mechanically so that no electricity is needed to crush them.

Pedal operated power generating system

 The pedal-powered systems can be used to recharge your cell phones, laptops or to power your camping outside. This is just a start but in the future, if it gets implemented in a local exercise parlor and in every bicycle in an optimized way, it can produce electricity on a large scale. Moreover, this method used successfully in the recent wall street demonstrations.


Things to know : 

Alternator: An alternator is an electromechanical device that converts mechanical energy to electrical energy in the form of alternating current.

Alternators generate electricity using the same principle as DC generators, namely, when the magnetic field around a conductor changes, a current is induced in the conductor. Typically, a rotating magnet, called the rotor turns within a stationary set of conductors wound in coils on an iron core, called the stator. The field cuts across the conductors, generating an induced EMF (electromotive force), as the mechanical input causes the rotor to turn.

Inverter: An inverter is an electrical device that converts direct current (DC) to alternating current.

Real Time Sorting Machine

It is a Candy sorting machine built in LEGO. It is using Java Optimized Processor which is mounted on the LRBJOP board. It is using a tilt-tray sorter method.

Why Real-Time Sorting used?
A tilt-tray sorter is a high-speed, continuous-loop sortation conveyor that uses a technique of tilting a tray at a chute to slide the object into the chute. It is used to expedite the process of Order fulfillment to consolidate line items of an order and to process returned products for immediate updating of inventory in real-time.

Helpful Resources : 

Java Optimized Processor :  

The unit controlling the LEGO motors and sensors is Java Optimized Processor (JOP). JOP is a Java processor, an implementation of Java Virtual Machine (JVM) in hardware.JOP executes Java Byte-code with precise timing constraints for each instruction, enabling execution time and scheduling verification.

Uppaal :
Implementation has been modeled and verified using Uppaal. Uppaal is an integrated tool environment for modeling, validation, and verification of real-time systems modeled as networks of timed automata, extended with data types (bounded integers, arrays, etc.)

Lego PCB : 

LEGO PCB is a robotics invention system of the LEGO Group. It was intended for children, but it turned out to be a great toy for adults, too. It combines electric components like sensors and actuators with Lego bricks and Lego Technical parts, such as gears, wheels, and axles, to build robots and other automated or interactive systems.
