DIY Wi-Fi ambient light that visualizes signal strength, channel traffic, and intruder alerts in real time—making wireless visible.

A LoRa transceiver dongle is a compact USB device equipped with a LoRa (Long Range) radio communication module.

An innovative earth auger blade design equipped with a robust safety guard, ensuring efficient soil drilling with maximum user protection.

The chicken coop door opener is based on ESP8266 board and it is controlled remotely by the Blynk App. It uses geared motor with 30 RPM, which have enough power to move the door. It is controlled by L298N board. For the supply of the motor is used 12V 3A AC/DC module. The microcontroller is supplied by 5V linear regulator board. The whole system is placed in a hermetic plastic box.

LoRaWAN + BroWAN tracker + TTN gateway yield a lightweight, cost-effective, long-range cat tracking system, bypassing commercial restrictions. Hardware and software are open to further customization and alert automation.

This system offers an automated attendance tracking solution by combining RFID technology with IoT capabilities—specifically, NodeMCU (ESP8266) for connectivity and Google Sheets for cloud-based record keeping. It enables real-time capture and tracking of attendance data

Upgrade your home or office security with this DIY Android Fingerprint Door Lock System powered by Arduino and Bluetooth technology! Once paired, you can unlock the door with just your fingerprint – no keys, no passwords!

We’ve all been there: you find the perfect spot in the library, ready to dive into your studies, only to be disrupted by a loud conversation nearby. Libraries are sanctuaries of silence, but maintaining that atmosphere is a constant challenge. Staff can't be everywhere, and often, people don't even realize they're being disruptive. This project was born from a simple idea: what if technology could provide a gentle, automated nudge to maintain a peaceful environment? I designed a smart, non-intrusive noise monitoring system that: Measures ambient noise in real-time. Provides immediate, visual feedback using a color-coded LED ring. Alerts library staff automatically via MQTT when noise exceeds a set threshold. Reports data to a live web dashboard for centralized monitoring.

Meet our Autonomous Sidewalk Delivery Robot – a smart solution for the future of last-mile logistics. With its robust steel design, LiDAR, Ultrasonic sensors, and GPS, it delivers goods safely and efficiently through urban sidewalks. Future IoT integration makes it not just a robot, but a step toward smarter and greener cities.

The heart of the project is the CrowPanel Advance, a compact and versatile device with esp32 that serves as the assistant's user interface. It's connected via WiFi to a dedicated AI server that I set up on an old laptop, which runs the Ollama software. This is the magic part: Ollama allows me to run powerful large language models locally, so all the processing happens right there.

This DIY electronics project demonstrates how to build an air/gas quality monitoring system using an Arduino, an MQ‑2 gas sensor, and an I2C LCD display. The setup detects gas concentrations such as LPG, CO, and smoke, and continuously displays real‑time levels on the LCD.

Using LoRAWAN to link a bunch of individual water sensors and soil hydration sensors, hooked up to a reservoir and water pump and valve system to make sure each plant is as hydrated as it needs to be, with Home Assistant compatibility.

This project presents the design and concept of a 10 cubic meter stainless steel storage tank made from grade 304L, intended for industrial and smart fluid management applications. The tank has been carefully designed to ensure durability, corrosion resistance, and suitability for integration with IoT monitoring systems. The tank structure includes a main cylindrical shell (virole), two dished heads (fonds), support cradles (berceaux), a lid (couvercle), a valve (vanne), and a custom nozzle (piquage) for input/output. It is designed to withstand varying fluid pressures and can be used in a variety of industries such as food processing, water treatment, chemical manufacturing, and agricultural storage. The CAD model has been developed using SolidWorks, employing sheet metal features and realistic welding simulations.

This project uses an Arduino Uno to integrate smoke, flame, light (LDR), rain sensors, an LCD display, and a buzzer to monitor environmental conditions. Alerts are triggered via the buzzer and real‑time statuses are displayed on the screen.
