Enigma – Mission X Challenge


Dear code breaker, I am contacting you from Bletchley Park as we are intercepting an increased volume of encrypted radio signals. We are working day and night to break the enigma codes that the German Navy are updating every day.

Enigma Machine Emulator

The enigma machine was used in World War II to encrypt secret messages.

The Enigma machines are a series of electro-mechanical rotor cipher machines. The first machines were invented at the end of World War I by German engineer Arthur Scherbius and were mainly used to protect commercial, diplomatic and military communication. Enigma

Binary Permutations Challenge


Did You Know?Everything that is stored on a computer is stored as binary code. Binary code is made of bits (0 or 1). We often use Bytes to store data. A Byte is made of eight bits and can be

Complementary Colours Algorithm


Complementary colors are pairs of colors which, when combined or mixed, cancel each other out by producing a grayscale color like white or black. When placed next to each other, they create the strongest contrast for those two colors. Complementary

My Weekly Timetable


A school timetable is displayed as a 2D table consisting of 5 rows (for each day of the week) and 5 columns (number of lessons in a day). Such a table can be stored in a computer program using a

Colour Difference Formula


RGB Colour CodesDid you know that every colour on the screen can be represented using an RGB code (Red, Green, Blue) code. This code consists of three numbers between 0 and 255, indicating how much red, green and blue are

Cell Phone Trilateration Algorithm


Mobile phone tracking is a process for identifying the location of a mobile phone, whether stationary or moving. Localisation may occur either via multilateration of radio signals between several cell towers and the phone, or simply via GPS. Mobile positioning is used by telecommunications companies to approximate

Weight on the Moon Calculator


Your weight is a measure of the amount of gravity exerted on your body by the planet Earth. On planet Earth, gravity has a value of 9.81 N/Kg (Newtons per kilogram). Because the Moon has about one-sixth of the gravity

Lissajous Curve Tracing Algorithm


Lissajous curves are a family of curves described by the following parametric equations: Lissajous curves have applications in physics, astronomy, and other sciences. Below are a few examples of Lissajous curves that you will be able to reproduce in the

The Honeycomb Challenge


Honeycomb is a structure of hexagonal cavities (cells of wax), made by bees to store honey and eggs. In this challenge we will use a set of iterative algorithms to draw a honeycomb pattern. First, we will create a function
