Drawing flags using Python Turtle

In this challenge we will use Python Turtle to draw a range of flags on screen. First, you will need to investigate the code used to create three different flags: France Sweden Czech Republic To understand these code snippets you

Boolean Algebra using Logic Gates

Boolean Algebra is used to simplify long/complex Boolean expressions. It is needed to optimise the use of logics gates (and hence transistors) when making an electronic circuit. Considering that the CPU is made of billions of logic gates, it is

Logic Gates Challenges

For this set of challenges, your task is to design logic gates circuits in order to produce the desired output for the given inputs as described in each challenge. You can combine as many logic gates as necessary using the

Digital Padlock using Logic Gates

In this post we are going to use logic gates and D-Type Flip-Flop circuits to create a 3-bit digital padlock with a stored combination that can be reset. Let’s first investigate how we are going to store the 3-bit combination

Design your own Logic Gates Circuits

In this blog post your will use our logic gates circuits simulator to create and test your own circuits. Circuit #1 Our first circuit will be based on the following Boolean Expression: Click on the above circuit to open it

Daily Protocolometer

In this post, we are investigating our daily use of the main protocols used when accessing the Internet while using our smartphone, laptop or desktop computer, tablet, smartTV or game console. Protocols are an essential concept to enable network communications

Hair & Beauty Salon – Entity Relationship Diagram (ERD)

“Stylish” is a Hair & Beauty Salon offering a wide range of hair & beauty treatments to customers. They currently employ five hair stylists and three beauticians. They currently use a notebook to record all their information such as customer

Creating Logic Gates using Transistors

As you know, computers can only process binary data which consists of 0’s and 1’s. This is due to the fact that the main processing components (e.g. the CPU) are made of transistors: tiny electronic switches that can be turned

The Lost Roman Sundial

Roman Britain was a period of nearly 400 years between AD 43 to AD 410 when large parts of Great Britain were under occupation by the Roman Empire. During this period, the Romans built roads and architectural structures that can
