FLC METER USING 16F877A (DE_METAL_AMIGO)

 

Inductors and capacitors are general purpose components in AC circuits. The estimation of exact or approximate values of inductance can be found in much theoretical way with the relation that they make with their physical dimensions. But who knows what exactly the show in practice. Even the slight change in the pitch of turns in case of inductance can change the resultant value. That was the intention that leads me to the build one.

The Rotating LED Clock

Time is an illusion...!!!!  

Mechanically scanning LED displays have a great place in the future. They may eventually replace the matrix of light bulbs found on standard displays. Spinning displays require much less power to drive the lights, as there is a fraction of the number of lights required in the matrix design. Our group hopes to take advantage of this and create an aesthetically pleasing clock. This clock also should keep the time accurately, slowly rotate the time so it is visible from all sides, is inexpensive to construct and maintain, and look more appealing than the average clock. The basic principle of working is the persistence of vision POV.

LUNAR LASER COMMUNICATION

INTRODUCTION

The present trends of communication are through transmission lines, optical fiber and microwave wireless communications. Fiber-optic communication is a method of transmitting information from one place to another by sending pulses of light through an optical fiber. Microwave transmission refers to the technology of transmitting information or power by the use of radio waves whose frequencies are  spectrum ranges across of roughly 1.0 (GHz) to 30 GHz referred as microwaves. These all type of communication technologies has their own disadvantages. In optical fiber communication losses like attenuation, absorption, scattering and radiative are occurred. Losses can occur in transmission lines if it shouldn’t perfectly terminated at its characteristic impedance. Microwave devices such as MASER can cause ozone depletion due to its high area of radiation.

Follower the Command Line :)

INTRODUCTION

What is a line follower?

            Line follower is a machine that can follow a path. The path can be visible like a black line on a white surface (or vice-verse) or it can be invisible like a magnetic field.

Why build a line follower?

Sensing a line and maneuvering the robot to stay on course, while constantly correcting the wrong moves using feedback mechanism forms a simple yet effective closed loop system. As a programmer you get an opportunity to ‘teach’ the robot how to follow the line thus giving it a human-like property of responding to stimuli.
