O ver speed indicator and Accident Avoidance systems in a four wheeler Except for the Autobahn in Germany, almost all roads have specific speed limits. And it is difficult for the driver to always look out for speed limits signs and adjust his speed accordingly. Over speed indicator is a device that tells the driver if he is exceeding the particular speed limit. With the  over speed indicator  in your car you can be sure that you are not going get yourself booked for over speeding. The system has a computer which stores the speed limits of different areas. The GPS in the system feeds the exact location of the car to the computer which looks up in its database to determine the permissible speed for the area and limits the car within the allowable speed. Accident Avoidance systems  in a four wheeler is a cocktail of several technological marvels. 1. Emergency Brake Assist (EBA) In an emergency, many people do not depress the brake pedal hard enough. EBA sense...

Robotics projects for engineering Students We humans tend to build machines which make our life easier and safe. From Ancient times we are constantly improving our lives with the help of machines. Robots are no different than that. We build robots to do things for us in a faster and safer way. Robotics is the branch of technology that deals with the design, construction, operation and application of robots.From bomb sniffing robots to autonomous devices for finding humans in wreckage to home automation, many people are interested in low-power, high speed, reliable solutions. Before we discuss any project idea, we need to know how should we select our project? For selecting any project you need to ask some questions to yourself fore example: Q1.) Is it beneficial for community ? Q2.) Does your robot solve any interesting technical  problem which can't be solved otherwise? Q3.) Does it justify its costs? Basic components to decide beforehand: Microcontroller...

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...
