This is certainly the cheapest and simplest Internet radio that you can make yourself if you have minimal knowledge in the field of electronics, and all thanks to this universal and practical display module.

I am Abdullah, a mechanical engineer specializing in high-quality CAD modeling and design. This single-seater Formula Student style race car showcases my skills in creating precise, functional, and visually appealing models. Featuring a lightweight tubular chassis, ergonomic bucket seat, aerodynamic rear wing, and detailed suspension and drivetrain systems, it demonstrates both technical accuracy and engineering creativity. I provide CAD modeling, 3D rendering, and manufacturing-ready drawings for automotive, mechanical, and industrial projects. My focus is on precision, practicality, and performance, turning concepts into professional, manufacturable designs that exceed expectations.

A reusable template for makers: touch UI, instant reaction, and MCU-based neural speech. CrowPanel UI + TinyTTS voice: instant offline speech on the MCU, ready to extend and remake.

A simple but very useful Zener diode tester

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

This is a “smart moving dustbin” (trash can) which can be controlled via smartphone (likely via Bluetooth or WiFi) and is capable of moving in all directions (forward, backward, left, right) under control

HackPlate is an open-source preheating station created for makers, repair technicians, and hardware enthusiasts who want full control over their tools. Built around a Raspberry Pi Pico (RP2040) and a Solid-State Relay (SSR 40A), it manages temperature control for PTC plates or heating elements with precision and reliability. HackPlate was designed as a transparent, modifiable, and educational tool — promoting the maker and hacker culture by encouraging learning, experimentation, and community-driven improvement. Anyone can modify the design, optimize performance, or contribute to its firmware and documentation.

This project demonstrates a basic electronic security system using an Arduino Uno, a 4x4 keypad, and a relay-controlled electric lock. When a predefined PIN code is entered correctly on the keypad, the Arduino activates a relay that unlocks the door for a short duration, then automatically locks it again. If an incorrect code is entered, access is denied. This system can be expanded with features like an LCD display, buzzer alerts, multiple user PINs, and tamper detection.

This DIY system is designed to detect motion using a PIR sensor and notify the user via the Blynk mobile app. It uses a NodeMCU (ESP8266) as the core IoT microcontroller, connecting wirelessly to your home network to send real-time alerts whenever motion is detected

This DIY electronics project showcases how to create a simple alcohol sniffing device using an Arduino and an MQ‑3 gas sensor. The system detects alcohol vapors in the environment—commonly used for breathalyzer-style applications—and provides immediate readings and visual feedback

This DIY project demonstrates how to create a real-time fire detection and alert system using a NodeMCU ESP8266, a flame sensor module, and the Blynk mobile app. When the flame sensor detects fire, the system alerts the user via the mobile app and optionally activates LEDs or buzzers locally

Turn voice into autonomy. Your mini rover learns to bypass obstacles and run full missions — all from simple commands.
