Random Access Memory using Logic Gates
In our previous blog post, “Binary Additions using Logic Gates”, we investigated how logic gates can be used together to create a circuit used in the ALU (Arithmetic & Logic Unit of the CPU) to add two binary numbers together.…
Binary Additions using Logic Gates
In our previous blog post “from transistors to processors” we found out that the CPU consists of logic gates, which are made using transistors. In this blog post we are looking at how these logic gates can be combined to…
From transistors to micro-processors
Vacuum Tubes and Transistors: Many consider the transistor to be one of the most important inventions of all time. Though the precursors of the transistor were invented in 1907 (at the time they were not transistors yet, they were vacuum…
Air Flight Route Planner
For this challenge you will use a graph data structure to create an Air Fligh Route Planner for a fictitious airline company offering flights across Europe. Here is a map showing all the direct flights offered by this airline company:…
The Social Network
Six Degrees of Separation The Six degrees of separation is an idea that was originally set out by Frigyes Karinthy in 1929 and that can be applied to Social Networks such as Facebook. It is based on the idea that…
Estimating Pi using the Monte Carlo Method
One method to estimate the value of π (3.141592…) is by using a Monte Carlo method. This methods consists of drawing on a canvas a square with an inner circle. We then generate a large number of random points within…
Space Invaders – 3D Pixel Art
In this blog post we will use Glowscript to create a 3D animation of a space invader. 2D Graphics used in retro arcade games consist of pixels. A 2D graphic can be described as a grid of pixels of different…
London Underground – Journey Planner
The aim of this Python challenge is to investigate how graphs can be used in Computer Science and investigate the key algorithms used when manipulating graphs in Python such as an algorithm to find the shortest path between two nodes…
