Understand the working of a 3D printer, check out the online resources. Understand what's an STL file, and then learn to slice it (using ultimaker or creality slicer).Go through the SOP'S regarding the 3d printer. Learn about bed temperature, infill density and other printer settings. Finally get an STL file from the internet, and slice it and put it for print.

● Create a folder named test.
● cd into that folder.
● Create a blank file without using any text editor.
● list the files in that folder
● create 2600 folders in this folder where each folder is named like . For example, M90 or B56.
● concatenate two text files containing any random text and display them on the terminal.

Dive into the core of machine learning by implementing Linear Regression from scratch using , and compare its performance with the scikit-learn implementation. Use the California Housing dataset to evaluate your model on real-world data.
- Implement linear regression manually (without using ML libraries for training).
- Understand and apply gradient descent to minimize error.
- Compare your custom model’s performance against
sklearn.linear_model.LinearRegression. - You should analyze results by:
- Graph showing line of best fit and the datapoints.
- Performance metrics: MSE, MAE, R² for both custom and scikit-learn models.
- Brief comparison between two models.

- Grasp how gradient descent optimizes weights in linear regression.
- Understand the importance of feature scaling.
- Know how to evaluate regression models using standard metrics.
- Be able to appreciate the convenience and performance of inbuilt ML libraries.
- Always normalize or standardize features before training your scratch model, especially if you’re using gradient descent.
- Be cautious with your learning rate , too small and the model is slow, too large and it may diverge.
- Initialize weights and bias properly ( small random values or zeros).
Get hands-on with NumPy and Matplotlib by solving a visual puzzle. You’ll be given a scrambled matrix, and your mission is to decode it into a hidden image using NumPy operations and visualization techniques.
- Download the scrambled matrix from the link provided.
- Use your knowledge of NumPy to manipulate, reshape, and reorient the matrix.
- Reveal the secret image by plotting it using
matplotlib.pyplot.imshow(). - Scrambled Matrix: Download Here

Decode the Matrix using these clues and Visualize it :
"Try reshaping the encoded array into a square—how many elements are there?""The structure may be upright, but the data might be sideways. Look at its orientation.""Sometimes the end is actually the beginning."
- Gain confidence with NumPy operations like reshaping, slicing, flipping, and transposing.
- Learn to visualize 2D arrays using Matplotlib.
- Sharpen your debugging and puzzle-solving skills in a fun context.
- Check the shape of the array before applying
imshow()- wrong dimensions will throw errors. - Ensure that your reshaped matrix has the correct number of elements (it's likely a square!).
Create a website to showcase your portfolio - about yourself, interests, projects, social media profiles and more. It has to be responsive and also pushed to the git repository. CSS can be of your choice and any framework can be used.
Markdown is an easy-to-use markup language that is used with plain text to add formatting elements (headings, bulleted lists, URLs) to plain text without the use of a formal text editor or the use of HTML tags. Markdown is device agnostic and displays the writing format consistently across device type. Write a technical resource article on a topic of your choice and post it on the MARVEL website. Refer to the linked article for further details
Create a tinkercad account, get familiar with the application, understand the example circuits given and simulate a simple circuit using an ultrasonic sensor to estimate the distance between an obstacle and the sensor. Display the results on the serial monitor.
Create a radar system utilising an ultrasonic sensor and servo motor to detect objects within a certain range. The ultrasonic sensor emits sound waves and measures the time taken for them to bounce back, while the servo motor rotates the sensor to cover a wider area, providing a simple yet effective detection mechanism.
