CIRCUIT IDEA: Two-Digit Counter
A two-digit counter is an electronic device that counts from 00 to 99, displaying the count on two 7-segment displays. With each clock pulse, the displayed value increments, resetting to 00 after reaching 99. The first decade counter controls the units digit, while the second manages the tens.

PROJECT: Face Recognition Using YOLO
This device integrates real-time face detection with a 5-point facial landmarking system to identify known and unknown faces. It serves multiple applications, from a face recognition-based doorbell to an attendance and time management system for MSMEs with fewer than 100 employees. | | |
Do-It-Yourself
CIRCUIT IDEA: Low-Cost Pulse Driver Circuit For Solenoids And Coils
A pulse driver circuit designed for solenoids and coils generates a short pulse of predetermined width to activate the solenoid, regardless of the duration of the input drive signal. This compact solenoid driver is useful for actuating solenoids in various devices and models, such as pinball machines or coil guns.

PROJECT: Touch To Roll: A Decoder-Based Dice
Electronic dice, or e-dice, are widely used today, but creating a design replicating the anticipation and randomness of a physical dice roll comes with its challenges. This device achieves that effect by generating a rolling motion that lasts approximately four seconds, though the duration can be adjusted by modifying the rolling steps. | | |
Do-It-Yourself
PROJECT: Automatic Daily Meal Reminder System
A structured meal plan consistently supports a healthy lifestyle, regulating body weight and reducing the risk of diabetes and cardiovascular diseases. An automated system addresses this by providing timely meal reminders and notifying parents for added reassurance. Built around an Arduino-based setup, it ensures adherence to a structured routine.

PROJECT: AI Vehicle Predictive Maintenance
Modern vehicle engines emit distinct sounds when operating normally or malfunctioning. AI-driven continuous monitoring detects abnormalities early, preventing costly breakdowns. This system leverages Google Teachable Machine to train an AI model to differentiate between normal and faulty engine sounds. Designed for predictive maintenance, the system offers a low-cost, efficient solution. | | |
