Disassembling and reassembling a computer
Here are pictures of the disassembling and reassembling project I did in my grade 11 engineering class.
During this project, I learned different parts of the computer such as:
-The RAM
-The Hard Drive
-The Optical Drive
-The Power supply
-The different type of cables
-The motherboard and all its components
You can click on the computer parts to see the definition.
In my grade 11 engineering class, I have learned gate logic which has helped me create a Half Adder, a full adder and a Two Full Adders. Here are pictures of this project :
Two Full Adders
On the left side, there is a picture of the 2 Full Adders circuit that I build. Later on, I built a circuit calculator that was doing binary addition. It could tell me the LED that was on using binary and decimal numbers. I used Scratch to make the Calculator. I made a program that was able to find the state of the circuit using a picoboard.
Using the programming language Python, I have created a Scientific Calculator that is able to solve multiple operations such as :
-Addition
-Subtraction
-Multiplication
-Division
-Modulo
-Raising to a power
-Square root
-Logarithm
- Sine, cosine and tangent
Throughout this link, you can download the script of the program :
Here is a picture of the program when it is started :
Scientific Calculator with Python
LED Bar Graph
Using my raspberry pi Zero, which is a tiny computer, I programmed a circuit of an LED Bar graph. The LED Bar graph is an electronic component made out of multiple LEDs. Using python and my raspberry pi, I was able to program the LED Bar Graph to make the lights flow like water.
Here is the python script that I wrote on my raspberry pi to be able to control the circuit :
