DiChokro is an affordable solution to tackle bicycle theft in developing countries. It includes a GPS-enabled device with a vibration sensor and processor, installed on the bicycle. The system connects to an Android app via the cloud, offering real-time tracking and secure parking location searches. With a production cost under $30, it ensures accessibility for a wide user base.
The Pathik application is an Android-based mobile app that helps users discover and learn about nearby historical sites. Using the phone's GPS, the app locates historical places in the user's vicinity and displays them in a list. Users can select a location from the list to view detailed information and watch a short video about the site, enhancing their understanding of its historical significance.
The Project presents a digital pattern lock system designed for securing electronic devices like doors and safes. It uses a 3x3 keypad (keys 0 to 8) where each keypress is converted from decimal to a 4-bit binary code. A pattern matching unit compares the entered sequence with a stored password, and if matched, triggers an output to unlock the system. The circuit is synchronized with a clock signal for accurate input detection and includes a reset function to clear wrong entries. This design offers a simple yet secure solution by combining user-friendly input with efficient digital processing.
