Software and Terminology

WEEK 01

Flameshot is what I use to take screenshots. It is super easy to use and makes capturing images quick and convenient.

Visual Studio Code is the open-source tool that I’ll be using to build my website and keep track of my work.

To compress my images, I used a combination of these two software tools. Both are very user-friendly and reduce image sizes by a considerable amount.

Here are some new terms that I came across this week:

Definitions of certain words have been AI generated (ChatGPT) for clear and concise definitions.

Local repository - The git project that is on your computer.

Remote repository - The same git project that is stored online.

Version Control - A system that keeps track of changes to your files.

Branch - A separate version of the code where changes are made.

Commit - A saved snapshot of code changes.

Pipeline - Automated steps that build, test, and deploy code.

CI/CD - Continuous Integration and Continuous Deployment is a practice that automates the building, testing, and deployment of software to ensure faster and reliable delivery.

.gitlab-ci.yml - A file that configures the pipeline.

Here are some basic git commands that I learnt this week:

git --version
Shows the version of Git installed.

git init
Starts a new repository.

git clone <repo-url>
Copies a repository.

git status
Shows file changes.

git add .
Stages changes.

git commit -m "message"
Saves changes.

git push
Uploads changes.

git pull
Gets updates.

git log
Shows history.

git branch
Lists branches.

git checkout <branch-name>
Switches branch.

git merge <branch-name>
Combines changes.

git remote -v
Shows remotes.

Week 02

Note: I have used AI (ChatGPT) to generate accurate descriptions of each software tool.

Gimp stands for GNU Image Manupilation Program. GIMP is a free computer program that allows you to edit and change pictures. I personally had a lot of fun exploring Gimp this week.

Inkscape is a free tool for making and adjusting vector graphics. At first, it was a bit tricky to use, but soon it became quite user-friendly.

To download Inkscape, go to the official website, and then navigate to the downloads section.

This tutorial helped me a lot.

Fusion 360 is a computer program used to design and build 3D models of objects. For me, fusion was a huge challenge in the beginning, but it got easier with practice.

Blender is a free software that lets you create 3D models, animations, and realistic images on a computer. It’s mostly used for designing objects, games, and visual effects.

Link to download Blender.

Onshape is a web-based design software used to create 2D sketches and 3D models directly in your browser. It’s commonly used for engineering and 3D design projects. Compared to Fusion and Blender, Onshape was relatively easier to use.

For compressing my videos, I have used FFmpeg. FFmpeg is a free, open-source software that works with video and audio files. It works through the command line.

Week 03

Here are some important terms that I learnt this week:

Kerf - The tiny amount of material that the laser burns away when it cuts.

Raster / Engrave - The laser moves back and forth to etch or shade the surface instead of cutting through.

Vector Cut - The laser follows a line to cut all the way through the material.

Power - How strong the laser is; higher power makes deeper or darker cuts.

Speed - How fast the laser moves; slower speed results in deeper or darker cuts.

Resolution - How detailed an engraving is; higher resolution gives sharper details.

Calibrate - Adjusting the laser so it cuts and engraves accurately.

Exhaust - Removes smoke and fumes while cutting.

Compressor - Blows air at the laser tip to keep cuts clean and reduce burning.

Press-fit joint - A joint where parts are pushed together tightly and are held in place by friction, without fasteners or glue.

Week 04

This week, there were a lot of terms that I came across. Note: I used Chat GPT for certain words to get clear and concise definitions. 😁

Microcontroller Unit (MCU) - A small computer on a chip that runs programs and controls hardware.

Processor (CPU) - The part of the MCU that executes instructions and makes decisions.

Development Board - A circuit board that holds an MCU and extra parts to make programming and testing easier.

Firmware - The program stored inside the MCU that tells it how to work.

Bootloader - A small program that allows new code to be uploaded to the MCU.

Peripherals - Built-in or external hardware that adds features like communication, timers, or sensors.

Power Pins - Pins that supply power to the board (such as GND, 3.3V, or 5V).

GPIO (General Purpose Input/Output) Pins - Pins that can be used as inputs or outputs.

Digital Pins - Pins that work with two states: HIGH or LOW.

Analog Pins (A0, A1, etc.) - Pins that read varying voltage values from sensors.

PWM (Pulse Width Modulation) - A way to simulate analog output using digital signals.

I2S Pins - Pins used for sending and receiving digital audio data.

Reset Button - Restarts the MCU and runs the program again from the beginning.

Port Multiplexer - Allows one pin to be used for different functions depending on settings.

IDE (Integrated Development Environment) - Software used to write, compile, and upload code to a board.

Arduino Language - A simplified programming language based on C/C++.

C Programming - A fast and efficient programming language used for low-level control.

Library - Pre-written code that makes it easier to use hardware features.

Function - A block of code that performs a specific task.

Variable - A named place to store data in a program.

Serial Monitor - A tool used to view messages sent from the MCU for debugging.

Write - Sending data to a pin, device, or memory.

Read - Receiving data from a pin, sensor, or memory.

Breadboard - A tool for building circuits without soldering.

Voltage (V) - The electrical force that pushes current through a circuit.

Current (A) - The flow of electricity.

Resistance (Ω) - How much a material resists the flow of current.

Ohm’s Law - Voltage equals current times resistance (V = IR).

Power Regulator - Keeps the voltage at a safe and stable level.

Resistor - Limits the amount of current in a circuit.

Capacitor - Stores and releases electrical energy.

Diode - Allows current to flow in only one direction.

Transistor - Acts as a switch or amplifier.

ADC (Analog-to-Digital Converter) - Converts analog signals into digital values.

DAC (Digital-to-Analog Converter) - Converts digital values into analog signals.

AC (Alternating Current) - Electricity that changes direction periodically.

Oscillator - Generates a clock signal that controls the MCU’s speed.

Registers - Very fast, small memory locations inside the processor.

Flip-Flop - A basic memory element that stores one bit (0 or 1).

Interrupt - A signal that pauses the program to handle an important event.

Instruction Execution Timing - How long the MCU takes to run instructions.

Address - A specific location in memory or a device.

Fuses (Configuration) - Special settings that control how the MCU behaves at a hardware level.
