Strategy IT: Cutting Costs, Not Corners: Building Large Scale Applications With Open Source Software Here are some strategies and best practices for leveraging open source to create enterprise-grade web and mobile applications without sacrificing quality or functionality.

Design CIRCUIT: Interesting Reference Designs Of Automotive Motor Drive	Design PCB: Designing PCBs For EMI Management Electromagnetic interference can derail your PCB’s performance. EMI management is not just a technical necessity but a hallmark of exceptional PCB design.

Design CIRCUITS: Why TMR Sensors Lead Next-Generation Design TMR sensors are gaining traction in industries needing precision and power efficiency. What makes them the go-to choice for modern designs?	Design SYSTEMS: Choose The Right Cloud Platform For Implementing IoT Protocols Working with IoT protocols like MQTT, AMQP, and CoAP on cloud platforms is essential for developing scalable and efficient IoT applications. The choice of the programming platform will depend on factors like project requirements, existing skills, and target devices. Leveraging the appropriate libraries and cloud services can enable seamless integration of IoT devices with cloud-based applications.

Do-It-Yourself PROJECT: IoT Smart Meter With Dashboard Energy meters in homes track electricity usage, enabling accurate billing by governments and providers. However, traditional meters often rely on manual readings, prompting consumers and industries to seek smarter alternatives with real-time energy usage and billing updates. While smart meters fulfil these demands, they frequently involve invasive installations, requiring complex wiring changes that risk short circuits and discourage adoption.	Do-It-Yourself CIRCUIT IDEA: Op-Amp-Based Vehicle Theft Detector A simple, low-cost device can effectively alert homeowners or occupants if a parked vehicle is moved or tampered with. This hardwired detector features a main circuit with a buzzer alarm installed inside the house, while a sensor is mounted on the vehicle being protected.

Do-It-Yourself PROJECT: Pi Zero Portable Bilingual Translator This system is designed as a bilingual translator, leveraging the gTTS library to support multiple Indian languages, including English (en), Bengali (bn), Gujarati (gu), Hindi (hi), Kannada (kn), Malayalam (ml), Marathi (mr), Tamil (ta), Telugu (te), and Urdu (ur). The two-letter codes in brackets specify the target language for speech conversion. For example: gTTS(text=translated_text, lang=dest_lang). Speech conversion between languages is straightforward—simply adjust the source and target language codes. For instance, Gujarati speech can be translated into Spanish by updating the relevant codes.	Do-It-Yourself PROJECT: BLDC Motor With Web-Based Speed Control Using ESP32 Integrating wireless control into brushless direct current (BLDC) motor systems opens up exciting possibilities for applications such as remote-controlled cars, robots, and other innovative systems. BLDC motors are commonly operated using a driver or a remote-controlled controller paired with an electronic speed controller (ESC). Adding Wi-Fi connectivity to enable control via a laptop or personal computer further enhances their versatility.

Do-It-Yourself PROJECT: ESP32-Powered Audio-Visual Siren This sound alternator is designed to simulate the effects of a police siren, combining sound and light to create a dynamic audio-visual experience. It uses an ESP32, a small speaker, and two red LEDs to alternate between sound signals and blinking lights. Control is achieved through code written in the Arduino IDE or MicroPython, utilising the GPIO pins of the ESP32.
