Solar seeker: In this project we design a solar seeker to follow a sun. solar seeker follow the sun and if the sensor attach on the sensor a sense a sun then solar seeker is stop automatically. Now after some time sun move from its position‚ then again seeker sensor sense the light and move the motor very slowly. If the sensor sense the signal then automatically stop the seeker . Movement of the seeker is restricted from left to right for limited area. To control the left and right limit

NON TRADITIONAL MANUFACTURING PROCESSES- An overview Introduction Non-traditional manufacturing processes is defined as a group of processes that remove excess material by various techniques involving mechanical‚ thermal‚ electrical or chemical energy or combinations of these energies but do not use a sharp cutting tools as it needs to be used for traditional manufacturing processes. Extremely hard and brittle materials are difficult to machine by traditional machining processes such as turning

patch antennas. Another area where they have been used successfully is in satellite communication. A. Project description The paper is about designing a Microstrip patch antenna. Physically it consists of a radiating patch on one side of a dielectric substrate which has a ground plane on the other side as shown in Figure 1. The patch is generally made of conducting material such as copper or gold and can take any possible shape. The

Rapidly occurring consecutive sparks produce a series of micro-craters on the work piece and remove material along the cutting path by melting and vaporization. The constantly flushing dielectric fluid washes away the particles. 1 WEDM Wire EDM machining (Electrical Discharge Machining) is an electro thermal production process in which a thin single-strand metal wire serves as the

SOLAR AUTO IRRIGATION USING SUN TRACKING TECHNIQUE INTRODUCTION: With the impending scarcity of nonrenewable resources‚ people consider to use alternate renewable sources of energy. From all available renewable resources‚ solar energy is the most abundant energy available and at the same time it can be easily converted into electrical energy. The solar energy refers primarily to the use of solar radiation for practical ends. Currently solar energy is very popular but a fixed solar panel cannot
