TASK : 3-D PRINTING

3-D priniting is the next big thing in the manufacturing industry additive 3-d printing and metal printing are the ones being worked upon now In 3-D printing the plastic filament of the desired type of material is selected and used to print the model we want This is mainly used becasue it increses the accuracy and precision of the parts being printed It's easy to print it then to make a mould ofr it and use it to manufacture It consumes a lot of less time and requires less human labour and efforts

OBJECTIVES OF THE TASK :

Understand the working of a 3D printer Understand what's an STL file, and then learn to slice it

My Understanding :

Major components of a 3-D printer are the:

X,Y,Z axised frame

Heated printing nozzle:the plastic filament gets heated and the stepper motors prints it accuratekly layer by layer the heated plastuc flows out through the nozzle getting printed layer by layer

Filament roll: the desired material for the printing is selected and its composite roll is placed to be fed the printing unit

Printing bed:all the heated filament gets printed on this printing bed it's where the final piece is present after printing it is coated with non adhesive and sticky coatings of ceramics and glss so that the printed piece dosent stick to the printe bed andit can be easily emoved after printing

STL files : It stands for stereolithography its the most comman file format used in 3D printing It describes the surface geometry of the of the 3D model It's basically a file extension which saves the file the stk format I used cults website to download the 3d model in stl format

SLICING: It's the bridge between our 3D model and the 3D printer It's a software that instructs the 3D printer how to print layer by layer our model to obtain the final piece It divide the model into many thin horizontal layers where each gets printed in a sequential order I used Ultimaker Cura TO slice the 3D model which I downloaded from cults to understand how slicing happens saw a youtube video on how to work in it

Conclusion :

How a 3D printer works The principles whic it harnours How the melted filament gets printed What is an STL file , why it's important What is Slicing and why its important for 3D printing How a file or model gets printed on the slicing principle

TASK : API [APPLICATION PROGRAMMING INTERFACE]

It is a set of rules that lets different software programs talk to each other, exchange data, and work together. You can think of it as a messenger that takes requests from one program, delivers them to another, and brings back the response.

OBJECTIVES :

Using any api of our choice to build an user interfacelike a web app or mobile app

MY LEARNINGS :

Learnt what is an API

It's applications and it's working principle

How it accepts info from user contacts the related , linked server and gets its info to the user

It basically acts as a bridge between the user and a data server accesing its informations

It's interface will be very user friendly and easy to use so that anyone can access it and obtain the information they need

How to link my js code and the api key to acess live information from the server and show it to the user

The interface can be both dynamic or static based on the coder its easy make a form for input type of text and submit and out it in the code it will make it dynamic

TASK : GITHUB

GitHub is a free, web-based platform where developers store code, track changes, and collaborate on projects.

It’s built on Git (a version control system) and is widely used for teamwork, open-source contributions, and project management.

OBJECTIVES :

Famirilize with interface and how it works and the various options present in it Issues, and pull requests with this task.

MY Learnings :

GitHub is a platform that helps developers store code, track changes, and collaborate. It uses Git for version control and adds features like repositories, branching, pull requests, and project boards.

How ton edit codes and how to save changes

How to check the libraries and see who edited and made changes to the code

FORKING

Making a PULL request

TASK : Ubuntu Command Lines and Promopts

Ubuntu is a free, open-source operating system based on Linux, designed to be user-friendly, secure, and versatile, making it suitable for desktops, servers, and cloud computing. In short, Ubuntu is preferred because it’s cost-effective, safe, customizable, and supported by a strong community, making it a reliable option for everyday use and learning.

The terminal comamnds are very case sensitive so that also should be kept in head

OBJECTIVES :

Understanding ubuntu as an OS Learning the basic commands in it Learning how to create and delete directories and files in the terminal Learning how to manipulate and copy files how to move files and directories Understanding the superuser

My Learnings :

In this task I learnt what is an OS like we all have used it but didn't know about it in depth I learnt how an OS works what all are its aspects and different types of OS which led to installing and learning ubuntu and it's essential command prompts There are many command prompts in it all follow a structured flow of command chain and many commands serves the same purpose like:

1.whoami and pwd There are some basic commands like pwd , cd , mv which are like the basic most commonly used and specific functions

Then comes some autroritative commands like:

mkdir : it is used to create new directories

rm : it is used to remove directories and files , files get deketed easily but if the any directory has any content it cannot delete those directories

-r : is an autoritative command which removes the files and directories even if it has any stored contents

-p : makes adirectory wirhin a directory

Key points to remember is that it's case sensitive and the usage of " .. " , " / " , " .. " should be proper and have proper ordered spacing between them so that the code gets executed perfectly as per the user requirements

Task : Article writing using Markdown

Markdown is not a programming language—it’s a lightweight markup language that makes text easy to format and read. In simple terms, it’s a way to add styles (like bold, headings, or lists) to plain text without complicated code.

OBJECTIVES :

Learn the basics of scripting language Learn how to format scrpits in markdown like bolds , italics , underlined with many different headings and adding images and viudeos to the scripted file

My Learnings :

Well I didn't have the liberty to fast learn this topic as all the MARVEL repoerts are to be written in this scripting language only so I had no other option but to learn about this in-detail

It's basically like HTML with a lesser number of functionalities

It can be best described as a notepad or journal file with a bit more formatting features such as adding photos and videos to it

It's applications can be found in article writing and report writings

There are a numbver of ways to use this editor

We can access it by notepad by typing the code and saving the file with " .md "extension or by VS code or any other text editor's

It can also be accessed using many online tect editors Learnt various ways you can add an image to this script by using github etc

TASK : K-MAP AND DERIVING LOGIVE GATES

K-MAP :

A Karnaugh Map is a graphical method used to simplify Boolean expressions. Instead of algebraic manipulation, you place values from the truth table into a grid and group them to find the simplest logic equation.

LOGIC GATES :

Logic gates are electronic devices that perform basic Boolean operations (AND, OR, NOT, etc.) on one or more inputs to produce a single output. They’re the foundation of digital electronics, used in computers, alarms, calculators, and more.

OBJECTIVES :

Determine the K-MAP and make a burglar alarm system using simple logic circuits. The buzzer or led's blinks when certain conditions are met, it utilizes push buttons for the door and key.

My Learnings :

Understood what a are logical gates , it's representation and it types , how it functions and the typess of operations it performs

Understood about K-Maps how to draw one and how to write it's truth tables and how to prove any given logical exquation using booloean algebra and how to draw truth tables for these boolean algebraic expressions

The burglar system activates the alarm when the door is open and the key is pressed. The alarm works on this principke that if the door is opened by an authoried entry and the key is again being pressed it's being pressed by an intruder

The K-MAP explaining this can be seen below :
