Simple Teaching Project
Electrostatics is a subject of great importance in sciences courses, addressing an important branch of physics: Electricity. In it, phenomena related to static electricity or accumulated electricity in bodies are studied. There is no doubt that the possibility of performing practical experiments, enriching the teaching, and stimulating the students' interest contributes to learning. But, to do exciting experiments, the electroscope is an essential resource, which is precisely what we propose to build in this article.
A parabolic sound reflector, similar to those used for satellite TV dishes, allows sounds to be super-concentrated, thus increasing the sensitivity of a microphone thousands of times and providing enormous directivity.
Have you ever heard that unwanted noise when turning a knob that changes the volume up and down on a stereo? As it is a mechanical component, many particles accumulate on the track of an analogue potentiometer, compromising the durability of this component and increasing the need for periodic maintenance. In a world where digital convergence increasingly transforms everything into zeros and ones, we present in this article the digital potentiometers, components that replace the analogue models with significant advantages.
A type of sensor that currently finds many applications in automation and other fields is the inertial sensor. Available in compact form for only a relatively short time, it has fantastic features that allow the creation of a multitude of new designs, as well as being used on a multitude of existing equipment. This article will analyze the working principle of inertial sensors and even suggest some practical applications.
1. What Is Analogue Computing
Analogue computing is named for working by analogy or systematic relationship between the physical processes in the computer and those in the system it is intended to model or simulate (the primary system).
This project converts the sound from a tape recorder, microphone, or even from a white noise source into light. The light will be modulated in amplitude with a response up to a few kilohertz. The circuit is very simple and also can be used in many experiments involving EIP and hypnosis.
