🧠 Inspiration

We’ve all left behind our favorite drinkware—at parks, jobsites, or long after a coffee run. What if your cup could remind you before you forget it?
DAMP – Smart Drinkware was inspired by this everyday problem, blending IoT, haptics, and app connectivity into a sleek solution that’s both fun and functional.

⚙️ What it does

DAMP is a smart drinkware ecosystem that:

Uses Bluetooth tracking to monitor drinkware proximity
Sends haptic alerts if you're walking away from your cup
Allows creation of safe zones (home, office) to prevent false alarms
Integrates with your mobile app for zone settings, device management, and alerts

🛠 How we built it

Hardware: BLE-enabled DAMP handle prototype built in SolidWorks and 3D printed
Mobile App: React Native + Expo Router for UI/UX
BLE Comms: react-native-ble-plx for device discovery and state sync
Cloud: Supabase for user auth and device data
Haptics & Alerts: Native vibration + system notifications
DevOps: GitHub Actions for CI/CD, ESLint for clean code, and Playwright for testing

// BLE listener setup
bleManager.onDeviceDisconnected(deviceId, () => {
  triggerAlert();
});

🧱 Challenges we ran into

BLE reconnection stability on Android and iOS
Accurate zone geofencing with minimal battery drain
Syncing device state to app UI in real-time
Handling Expo/React Native quirks when integrating native modules like react-native-haptics and ble-plx

🏆 Accomplishments that we're proud of

Built a working BLE-connected prototype in under 48 hours
Designed a clean, intuitive mobile interface
Created a reliable zone-based alert system that feels native and non-intrusive
Made people laugh and want one

📚 What we learned

How to connect BLE hardware to Expo apps using ble-plx
How to work across hardware, software, and UX in a rapid timeline
That good UX matters even for something as simple as a coffee handle
How to set up GitHub workflows that test and lint automatically

🚀 What's next for DAMP – Smart Drinkware

Add subscription zones and multi-device support
Ship the handle as a modular product for existing cups (Yeti, Stanley, Hydroflask)
Expand into Smart Hydration Alerts for daily water tracking
Launch on wecr8.fun and collect user feedback
