| ===== 6. Hackathon projects ===== | ===== 6. Hackathon projects ===== | ||
| + | |||
| + | The goal of the hackathon is simple: | ||
| + | |||
| + | * build a useful, fun, or technically impressive smartwatch app | ||
| + | * use the above starter project as the base | ||
| + | * demo the app running on real watch hardware at the end of the event | ||
| + | |||
| + | Participants should focus on binging up watch hardware, contributing to the Hacktor Zephyr port and building a single polished app, not a full smartwatch operating system. | ||
| + | |||
| + | ==== Suggested Projects ==== | ||
| + | |||
| + | This is just a list of ideas to get you started. They are purely for orientation purposes, you can choose to implement them or you can propose a totally different project. | ||
| + | |||
| + | === 1. Fitness Tracker === | ||
| + | |||
| + | * **Difficulty:** Medium | ||
| + | * **Main hardware:** IMU, display, touch, haptics, fuel gauge | ||
| + | * **Core idea:** Count steps, estimate activity level, and show progress toward a daily goal. | ||
| + | * **Minimum viable demo:** Step counter, distance estimate, calories estimate, daily goal ring. | ||
| + | * **Stretch goals:** Auto-walk detection, inactivity reminders, workout mode, local history, sync with a mobile app. | ||
| + | |||
| + | === 2. Watchface Studio === | ||
| + | |||
| + | * **Difficulty:** Hard | ||
| + | * **Main hardware:** display, touch, battery gauge, BLE optional | ||
| + | * **Core idea:** Build custom watchfaces with selectable themes and complications in a web app. Upload these watchfaces to the watch. | ||
| + | * **Minimum viable demo:** At least three watchface styles with time, battery, and date. | ||
| + | * **Stretch goals:** Animated watchface, gesture wake, synced phone weather, editable layouts. | ||
| + | |||
| + | |||
| + | === 3. BLE Phone Companion === | ||
| + | |||
| + | * **Difficulty:** Medium to Hard | ||
| + | * **Main hardware:** BLE, display, touch, haptics, speaker optional | ||
| + | * **Core idea:** Connect to a phone app and exchange useful data. | ||
| + | * **Minimum viable demo:** Phone connects over BLE and sends notifications or simple text messages to the watch. | ||
| + | * **Stretch goals:** Music controls, find-my-phone, phone battery sync, quick replies. | ||
| + | |||
| + | === 4. Gesture Remote === | ||
| + | |||
| + | * **Difficulty:** Medium | ||
| + | * **Main hardware:** IMU, BLE or Wi-Fi, haptics | ||
| + | * **Core idea:** Use wrist gestures to control another device. | ||
| + | * **Minimum viable demo:** Recognize 2-3 gestures and map them to actions such as next slide, previous slide, play/pause, or camera shutter. | ||
| + | * **Stretch goals:** Calibration mode, gesture training, context-aware control modes. | ||
| + | |||
| + | === 5. Pomodoro / Focus Coach === | ||
| + | |||
| + | * **Difficulty:** Easy | ||
| + | * **Main hardware:** display, touch, haptics, speaker optional | ||
| + | * **Core idea:** Help the user stay focused with work/break cycles. | ||
| + | * **Minimum viable demo:** Configurable timer, session progress, vibration alert at timer end. | ||
| + | * **Stretch goals:** Habit streaks, productivity stats, distraction tracking, BLE sync to a phone. | ||
| + | |||
| + | |||
| + | === 6. Voice Memo Watch === | ||
| + | |||
| + | * **Difficulty:** Hard | ||
| + | * **Main hardware:** microphone, speaker, flash, PSRAM, touch | ||
| + | * **Core idea:** Record and play short voice notes directly on the watch. | ||
| + | * **Minimum viable demo:** Record, save, list, and replay short clips. | ||
| + | * **Stretch goals:** Compression, timestamps, BLE export to phone, keyword tagging. | ||
| + | |||
| + | === 7. Fall Detection / Safety Alert === | ||
| + | |||
| + | * **Difficulty:** Hard | ||
| + | * **Main hardware:** IMU, haptics, BLE | ||
| + | * **Core idea:** Detect a likely fall and trigger an alert flow. | ||
| + | * **Minimum viable demo:** Simulated fall detection with on-watch confirmation and BLE alert message to a phone app. | ||
| + | * **Stretch goals:** Motion confidence scoring, inactivity follow-up, emergency contact workflow. | ||
| + | |||
| + | === 8. Sleep / Restlessness Tracker === | ||
| + | |||
| + | * **Difficulty:** Medium | ||
| + | * **Main hardware:** IMU, fuel gauge, display | ||
| + | * **Core idea:** Track overnight movement and estimate sleep quality. | ||
| + | * **Minimum viable demo:** Movement logging, simple sleep score, timeline of motion intensity. | ||
| + | * **Stretch goals:** Smart wake-up window, sleep trends, nap mode, phone sync. | ||
| + | |||
| + | === 9. TinyML Activity or Keyword Detector === | ||
| + | |||
| + | * **Difficulty:** Hard | ||
| + | * **Main hardware:** IMU or microphone, PSRAM, flash, display | ||
| + | * **Core idea:** Run a lightweight ML model on-device for activity classification or keyword detection. | ||
| + | * **Minimum viable demo:** Recognize a few gestures, motions, or spoken keywords and react in the UI. | ||
| + | * **Stretch goals:** User training data collection, confidence metrics, low-power trigger mode. | ||
| + | |||
| + | === 10. IoT Dashboard / Smart Home Controller === | ||
| + | |||
| + | * **Difficulty:** Medium | ||
| + | * **Main hardware:** Wi-Fi or BLE, display, touch, haptics | ||
| + | * **Core idea:** Turn the watch into a compact controller for sensors or smart-home devices. | ||
| + | * **Minimum viable demo:** Show live values such as temperature, light, or room status, and toggle at least one remote action. | ||
| + | * **Stretch goals:** Home Assistant integration, quick scenes, secure pairing, offline cache. | ||
