A physical blink-rate monitor device that helps users become more conscious of their blinking while studying digitally. The device includes: A button for the user to press every time they blink A display screen showing: Blinks per minute Timer counting to 60 seconds before reset Target blink range (10–15 blinks/min) An Arduino-based system housed in a rounded 35x35x50 mm enclosure Built using Arduino IDE, basic electronics components, and laser cutting The device encourages users to meet a minimum blink rate goal, indirectly reducing eye strain. 

SDG Focus: None explicitly stated in content (likely SDG 3 – Good Health and Wellbeing) Constraints Addressed: Students are not self-aware enough to monitor blinking manually Blink monitoring shouldn't distract from actual learning Idea Brainstorming Approaches: Monitoring Blinks: Using physical counters or software to track blink frequency Stress Stimuli: Triggering blinking through jump scares or alarm sounds (eventually not chosen) Prototyping & Testing: Hardware & enclosure design with soldered Arduino components Tested on two users (sister and student) Blink rates improved by 3.37% (sister) and 7.79% (student) Prototype refinements were made based on usability and visibility feedback Results & Conclusion: Moderate increase in blinking confirmed the effectiveness of the prototype Target feature might have had limited impact due to low baseline blinking rates The second prototype was more effective, especially for underprivileged users External variables (screen size, eyesight, lighting) could have affected results Overall, it increased awareness and offers scope for improvement Skills Applied: CAD | Electronics | Design Thinking | Programming | Soldering | Prototyping | Laser Cutting Contributor: Siddhant Agarwal
