In this guide, we will explore how to implement a control system where you can command the drone's movement using keyboard controls (WASD keys), and when you release those controls, the drone automatically maintains its position in space. This creates an intuitive flying experience where you get the precision of manual control when you need it, combined with the…

The Maneuver Control system is the final logical extension of the LiteWing Flight Positioning Module. While the Position Hold system focuses on maintaining a fixed point in space, maneuver control enables the drone to intentionally move to new positions while remaining fully autonomous and stabilized. The key distinction is that maneuver control does not introduce…

A robotic arm is one of the most popular projects that almost every electronics enthusiast tries to build at least once in their life. Robotic arms are fascinating projects because they can be built for many practical applications, such as pick-and-place operations, component assembly, repetitive tasks, and even creating intelligent systems like the robotic arm “…

Text-to-Speech, or TTS, is a technology that converts written text into spoken audio. It is widely used in voice assistants, accessibility tools, alert systems, kiosks, and smart devices. Today, ESP32 Text to Speech using AI has become a common approach for adding voice output to small electronic projects. On computers and smartphones, TTS works smoothly because…

In an era of endless notifications and remote work, our greatest challenge isn't a lack of tools, it’s a lack of focus. We often turn to our smartphones for a simple timer or a to-do list, only to find ourselves sucked into social media ten minutes later. This "Digital Fatigue" is a real problem, I faced similar problems while studying for my exams. I realized that using…

Ever wondered if a small, low-cost board like the ESP32-CAM can actually recognise objects or even identify Indian currency notes? In this project, the answer is a clear yes. We combine the ESP32-CAM with the powerful Edge Impulse platform to build a system capable of object detection and image classification right at the edge. By using the Edge Impulse at every step…

I built a Smart Auto-Assist Home Safety System that simulates a real smart home using an ESP32 and an ESP32-S3-BOX3. The system automatically controls lighting and appliances based on ambient light and human motion, continuously monitors electrical energy usage, detects abnormal current faults, and predicts electricity consumption and billing using lightweight on-device…

HestiaGuard is a distributed home management and power‑control system built around ESP32 microcontrollers. The project combines environmental monitoring, electrical usage tracking, and centralized control to improve household safety and energy efficiency.

The xcc700 is a very small, lightweight C compiler designed specifically for the ESP32 microcontroller. It is like a mini version of GCC or clang, but this system has some limitations. Instead of generating Windows .exe files, it produces ELF binaries for the Xtensa CPU, which is the processor architecture used in ESP32. Because it is so small, the compiler itself can run on the ESP32 and…

Researchers from the University of Pennsylvania and the University of Michigan have unveiled the world’s smallest fully programmable autonomous robots. Measuring just 0.2 × 0.3 × 0.05 mm, these microscopic swimming robots are barely visible to the naked eye yet can independently sense their environment, process information, and perform programmed tasks. Each robot integrates sensing,…
