Sixth Sense technology of Pranav Mistry

'SixthSense' is a wearable gestural interface that augments the physical world around us with digital information and lets us use natural hand gestures to interact with that information.

The SixthSense prototype comprises a pocket projector, a mirror and a camera contained in a pendant like, wearable device. Both the projector and the camera are connected to a mobile computing device in the user’s pocket. The projector projects visual information enabling surfaces, walls and physical objects around us to be used as interfaces; while the camera recognizes and tracks users' hand gestures and physical objects using computer-vision based techniques.

Autonomous Agile Aerial Robots

The most effective way to build autonomous aerial vehicle is quad rotor.

A quadrotor, also called a quadrotor helicopter or quadrocopter, is a multicopter that is lifted and propelled by four rotors.

University of  Pennsylvania professor Vijay Kumar and his team developed such a quad rotor robot which can operate autonomously without the help of  remote control or GPS System.

Power Generation using Foot Steps

Scientists at the University of Hull are researching ways of turning human motion into electricity.
They are working on a prototype staircase that converts the movement of people walking up and down it into a power source.This project is similar to Human Powered Harvesting as discussed before on this blog.

RFID based mobile payment system

Mobile payment is an alternative payment method. Instead of paying with cash, cheque or credit cards, a consumer can use a mobile phone to pay for a wide range of services and digital or hard goods.

Radio-frequency identification (RFID) is the use of a wireless non-contact system that uses radio-frequency electromagnetic fields to transfer data from a tag attached to an object, for the purposes of automatic identification and tracking. Some tags require no battery and are powered by the electromagnetic fields used to read them.

Mobile Payment system is a service that aims to securely and conveniently move retail banking and financial services to cell-phones. It is a mobile-banking facility for the unbanked.

Human Tracking Fan System

Fan is one of the most important tool that human beings have ever developed.First fan came into existence in India.The punkah fan was used in the India in the early 500 BC. It had a canvas covered frame that was suspended from the ceiling. Servants, known as punkawallahs, pulled a rope connected to the frame to move the fan back and forth.In 19th century Industrial Revolution took place and fan kept on evolving ever since.

What's the significance in Fan in Modern World?

Fan is the most important electronic machine for poor living all across the world. It is not costly as Air conditioners and coolers, runs on low power and easy to carry(table fan).

The only problem with table fan is its inefficiency, we need to adjust it according to our position or start its motor which rotates it all over the place in 180 degrees and wasting its power by directing air at empty spaces for much of the rotation cycle.

What is Human Tracking Fan System ?

We are trying to build a fan which can track human and adjust itself according to the position of a person sitting in a room.

How it works ?

It consists of two PIR Sensors which can detect person sitting position because humans typically radiate more infra-red light than their surroundings, such as a wall for instance, detecting motion is fairly simple.

How to build one ?

Online health monitoring


Imagine a world where you do not need to visit your doctor for your regular checkup.All you need is a simple device called online health monitor system.

This is three steps process :

1. Using health monitor equipment's it gets relevant information about your body.

2.Then computer process this information and update it to the server.

3.Any user around the world can access this information in real time with the help of ip address of the server computer.

GSM Operated Robot

Mobiles are very common today and there are very few places left where mobile signals can't reach.Imagine, when you can control robots from anywhere in the world and  this is now possible with GSM operated robot.

Analysis of EGR emission reduction technique

In internal combustion engines, exhaust gas recirculation (EGR) is a nitrogen oxide (NOx) emissions reduction technique used in petrol/gasoline and diesel engines. EGR works by recirculating a portion of an engine's exhaust gas back to the engine cylinders.

 In a gasoline engine, this inert exhaust displaces the amount of combustible matter in the cylinder. In a diesel engine, the exhaust gas replaces some of the excess oxygen in the pre-combustion mixture. The principal function of EGR to reduce the amount of NOX that is produced during the combustion process Nox is created by high combustion temperature that allowed the Nitrogen and Oxygen to combined and form Nitrogen Oxide. A combustion temperature of at least 2500 degree is required to form Nitrogen oxide. We use exhaust gases to curb that temperature inside  the chamber.

Bio Gas powered vehicle

Although we have discussed lot of project ideas related to bio gas on this blog, but as you know, none of these include powering our automobile engines using bio gas.I recently searched for this topic and found that in 1974, a British documentary film entitled Sweet as a Nut detailed the biogas production process from pig manure, and how the biogas fueled a custom-adapted combustion engine.In 2007, an estimated 12,000 vehicles were being fueled with upgraded biogas worldwide, mostly in Europe.

I want you to build project which is powered by bio gas engine.

360-degree panorama Camera

"A picture is worth a thousand words" refers to the notion that a complex idea can be conveyed with just a single still image. Camera is integral part of human life, we can't imagine living without it.Without camera too, humans were very much interested in depicting themselves on the paper,when there was no camera around,painters played the role of camera.Even, you can find photographs of emperors and scientist from last centuries painted by that time great painters.

Control your devices using eye contact



This project is about controlling devices using our eyes. Imagine when you can use your eyes to scroll your computer screen up and down with your eyes movement. This project is also important for online marketing companies to find out exactly where they should place there advertisement to get maximum attention of the user.This can also be used in Video games where protagonist  needs to look around.

Eye tracking is the process of measuring either the point of gaze ("where we are looking") or the motion of an eye relative to the head. An eye tracker is a device for measuring eye positions and eye movement. Eye trackers are used in research on the visual system, in psychology, in cognitive linguistics and in product design.

The Eye Tracking Device (ETD) is a headmounted device, designed for measurement of three-dimensional eye and head movements under experimental and natural conditions. The tracker permits comprehensive measurement of eye movement (three degrees of freedom) and optionally head movement (six degrees of freedom).

There are a number of methods for measuring eye movement. The most popular variant uses video images from which the eye position is extracted. Other methods use search coils or are based on the electrooculogram.

Tiny Biogas generator

What is Biogas?

Biogas typically refers to a gas produced by the Anaerobic digestion.Anaerobic digestion is a series of processes in which microorganisms break down biodegradable material in the absence of oxygen.Organic waste such as dead plant and animal material, animal dung, and kitchen waste can be converted into a gaseous fuel called biogas.
