Most DIY projects stay on the workbench because they look like science experiments. The OG DIY Smartwatch is the result of a nine-month engineering journey to prove that 'DIY' can mean 'Daily Driver.' After seven mechanical revisions to master SLA resin tolerances and light-bleed, I’ve transformed a bare ESP32-C3 circuit into a sleek, open-source wearable. It features a 350-nit IPS display, custom LVGL-based OS, and phone-synced navigation—all built for a fraction of the cost of a retail watch. We built it cheap, but we wear it proud.

In this project, we’ll turn the Elecrow 7" ESP32-S3 HMI display into a complete UPI payment interface for a vending-machine-style system. You’ll learn how to design the UI in SquareLine Studio, generate a dynamic UPI QR code based on selected items, and print a payment receipt using a thermal printer — all driven by a single ESP32-S3 board.

This project is a working model inspired by ISRO's Chandrayaan-3 lunar rover mission. The purpose of the project is to help students understand the basics of robotics, obstacle detection, and wireless control using Arduino and ESP8266. The rover model replicates the concept of terrain navigation and autonomous obstacle avoidance.

This project develops a LoRa-based Smart Agriculture Monitoring and Irrigation System to optimize water usage and improve crop health. It uses a LoRa module to transmit soil moisture, temperature, and humidity data from remote fields to a central gateway, enabling farmers to monitor conditions and automate irrigation.
