| ## Team Members - Areg Gevorgyan - Alan Ilinskiy ## Problem Ideal drink temperatures don’t last. Hot drinks cool too quickly, and cold drinks warm up. Existing solutions like thermal mugs only slow heat loss and mostly work for hot drinks, while ice cubes dilute flavor. ## Solution A smart coaster that actively maintains a user-selected drink temperature. The device can both heat and cool using a reversible thermal plate, allowing instant switching between modes. A temperature sensor measures the drink surface, and a microcontroller runs PID control to stabilize and hold the desired temperature. The user sets their preferred temperature with a knob and views it on a small display; the coaster automatically adjusts to lock in that temperature. ## Solution Components ### Subsystem 1: Microcontroller and Control Logic Handles system control, PID loop and user input. **Components:** STM32 microcontroller ### Subsystem 2: Thermal Regulation Actively heats or cools the drink by reversing current direction. **Components:** High-power Peltier module, custom H-bridge / power PCB ### Subsystem 3: Temperature Sensing Continuously measures drink temperature for closed-loop control. **Components:** IR temperature sensor ### Subsystem 4: User Interface Allows users to set and view temperature preferences. **Components:** Rotary encoder (knob), display ### Subsystem 5: Power Supplies and regulates power for logic and high-current thermal control. **Components:** External power adapter, onboard voltage regulation ## Criterion for Success - Maintains user-set temperature within ±5°C - Seamlessly switches between heating and cooling - Stable PID control with no oscillation - Intuitive temperature selection via knob and display |
