 Hacktor is **not** (yet) an upstream Zephyr board (maybe you could help with that?), so we need a compatible Zephyr board definition to build/flash a first image.

 ===== 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.
