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.
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.
Images and sounds can be combined in many paranormal experiments. Not only are the images picked up from the TV receiver suitable to experiments, but also static images that can be photographed with standard or Polaroid cameras.
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.
This is an original story by John T. Frye from 1954 in his Mac’s Service Shop series, which, as I already indicated in the Adventures of Professor Ventra, Beto and Cleo, who inspired me in the creation of the characters.
