Do-It-Yourself CIRCUIT IDEA: Multi-Purpose Wire-Loop Security System This multi-purpose security system utilises wire loops to secure items. Wire loops can be employed in various ways for security applications such as luggage security, bike security, bicycle security, room security, and door security. A wire loop, when attached to security items and alarm mechanisms, detects and alerts in case of unauthorised attempts to tamper with the wire loop | Do-It-Yourself PROJECT: Smart Water Serving Robot With the advent of artificial intelligence, robots find application in various sectors such as industry, homes, bars, restaurants, events, agriculture, and even space. In light of the broad scope of robot applications, this smart water serving robot was developed. While there are several water-serving robots on the market, many are costly and complex in design and heavy in weight |
Do-It-Yourself PROJECT: Adding Location Tracking To The Wearable Interface Device Here’s how you can add location tracking, without GPS, to the project for a smartwatch-like HID with keyboard and touchpad, which was published in March issue. Traditional GPS-based systems have limitations, especially indoors or in areas where signals are too weak or difficult to get due to obstructions | Do-It-Yourself PROJECT: pH Measurement In Hydroponics System The base setup for this system is located in a room with approximate dimensions of 9.29 square metre. The room is non-air conditioned and does not receive any direct sunlight. The proposed setup aims to evaluate the feasibility of utilising an electrode-based E201 BNC pH measurement sensor for assessing the pH of the water before and after the addition of liquid nutrients |
Do-It-Yourself PROJECT: Gadget For Dual Protection From Viruses The Corona pandemic is over officially but its ill effects are still being seen, especially in crowded places like popular markets and malls. Besides, one needs to guard against new viruses and mutations of Corona | Do-It-Yourself PROJECT: Shop Billing System Using A Thermal Printer This shop billing system is a comprehensive solution aimed at streamlining transaction management within a retail environment. Combining Python for graphical user interface (GUI) functionality and Arduino for controlling a thermal printer (RP203), this innovative system enables users to input customer details, select items from an inventory, manage a cart, and seamlessly print bills.
