The work presented here was originally developed on an FPGA in VHDL. As a starting point, we are going to describe the AES architecture and codes written in

INTRODUCTION Convolutional codes are a type of error correcting codes targeted to fix the errors introduced by the channel. In a code block, the source data stream is

The Matlab code for this post is provided on Mathworks at: https://uk.mathworks.com/matlabcentral/fileexchange/57033-face-recognition-algorithm-using-sift-features It also requires additional files such as Sift.exe; please email us at contact@behindthesciences.com to get a copy.

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

A few years ago, we were interested in acquiring a 3D printer to allow use to print mechanical parts for our projects. We ended up buying a Makerbot

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

We recently upgraded our internet to fibre (fibre to the cabinet) and we thought it was about time to upgrade our faithful Linksys WRT54G. As you probably already know,

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.

This post describes the use of an ultrasonic sensor to measure distance of a target. The goal of this post is to help you understand how this sensor works
