  • 3D Printed Right-Angle Friction Drive Using Cam and Follower

    In this project we explore a simple but powerful mechanical idea:how a rotating cam and a disc-type follower can be used to create a right-angle friction drive — without gears, belts, or electronics. This entire mechanism is 3D printed and demonstrates how motion can be transferred purely through geometry and contact. 📹 Project Video https://youtube.com/shorts/w_zL9D7RV9Q…

  • Smart City Mini Project Using Arduino UNO

    (Street Light Automation, Smart Gate & Air Quality Alert) Smart cities are built by combining automation, sensing, and decision-making.In this project, a Smart City model was developed using an Arduino UNO and commonly available sensors to demonstrate how embedded systems can be used for urban automation. This project focuses on real-world logic, not just blinking…

  • Arduino Uno Dot Matrix Display Using MAX7219 (Scrolling Text)

    In this project, we interface an 8×8 Dot Matrix Display (MAX7219) with Arduino Uno to display scrolling text using the MD_Parola library. This setup is ideal for learning: All components, wiring, code, and flashing are available on a single page for smooth lab execution. Circuit Diagram (Arduino Uno + MAX7219) The circuit below shows the…

  • AI Robot Head Tracking Using Browser Vision (No Training, No Server)

    Turn your head left, right, up, and down. Connect Direction: Flipped Download FreeCAD project and STL files Introduction Most “AI robot face” demos rely on heavy machine-learning models, cloud APIs, or large datasets.This project explores a different approach: Using simple geometry and browser-based vision to create an expressive robot head that reacts to human movement…

  • RGB LED with Arduino UNO/Nano

    What is an RGB LED and What Are We Building Here? An RGB LED is a special type of LED that contains three LEDs inside one package — Red, Green, and Blue.Using these three colours, the Arduino can blend them at different brightness levels to produce hundreds of colours like yellow, cyan, purple, pink, white,…

  • 3D printer setting for shiny prints

    I made a Cylindrical box for storing my leftover spices. So i made it, sliced it and let it to print. It was a H: 100mm , R: 60mm. On roughly about 20mm i changed the speed of the printer to just 25%. I found out that at 25% of the speed the print lines…

  • Make a Joystick-Controlled Car with ESP32 and NodeMCU

    Are you interested in making a remote-controlled car using ESP32 and NodeMCU? In this project, we will use a joystick module to control a car wirelessly. This is a fun and simple way to explore ESP-NOW communication and motor control! What You Need To build this joystick-controlled car, you will need: How It Works Wiring…

  • CREALITY Ender-3 V3 KE

    I bought the printer from wol3d’s New Delhi office. I am a electronics guy but i have inclination towards the 3d printing world. The feeling that you can design and make something in front of you. It’s a slow process but this printer comes with a slicer software which is fast. Build Volume : 220…
