In this post, we are going to copy and send a 433 MHz signal. The signal source is a garage key fob, as these signals don’t have encryption

At Behind The Sciences, we are always pleased to launch a new category and we think this one is going to be specially interesting for you! 🙂 In

In a previous post, we showed you how some email providers can be unsecure. We thought let’s try to prove it with the most popular email provider: gmail.

Source An electric circuit breaker is an important part of any electrical wiring system. It is designed to interrupt the flow of electricity the moment a fault, such

  In our previous posts series on this section, Distributed Element Model in Transmission Lines, we analyzed the transmission lines as a function of the z coordinate, in the

  This is the last part of the Distributed Element Model in Transmission Lines, where we are analyzing the transmission lines as a function of the z coordinate,

Doppler Radar System Description The Doppler radar performance makes an optimum use of the transmitted power and its weight is appropriate to be used in aircrafts. In addition,

In this post we are going to develop the Hamming Code error correction algorithm in Matlab, so the first thing you need to do is to download our

In this article we discuss a UPS circuit powered from mains supply. The backup power is provided by NimH batteries.  Figure 1 : UPS schematic   The power

Introduction Radiation detection systems often consist of a detector, a charge sensitive pre-amplifier, a pulse shaping amplifier and a multi-channel analyser. The detector converts interaction of photon energy from an

The post briefly shows a circuit that could be used to transmit data optically (through the air) to a receiver. In this case, we made a circuit to

This tutorial post is on how to build a simple thermistor circuit. There is a variety of temperature sensors on the market all of which meet specific application needs.
