Project description:
"I’m taking Belflör Bloom from concept drawings to a fully working wrist-mounted prototype and need end-to-end help—hardware, firmware, and interface all in one coordinated build.

Core function
The first release has a single job: effortless music control. Play, pause, skip, and volume adjustments must work through three parallel input methods—capacitive touchscreen gestures, voice commands, and tactile side buttons. No health tracking or notification features are required at this stage, but the architecture should leave room for them later.

What the work involves
• Hardware: board layout, component selection (BLE-enabled SoC, microphone array or MEMS mic, haptic motor driver, battery management, low-profile tactile switches, 1.4-1.6" touchscreen), enclosure fit for small-batch 3-D printing or CNC.
• Firmware: real-time OS or bare-metal code that handles Bluetooth AVRCP, low-power states, touch controller, physical button debounce, and hotword or on-device voice recognition hooks.
• Companion app stub (Android/iOS) only as needed to pair and relay audio commands.
• UI: simple monochrome or low-color interface with smooth transitions; design assets can start in Figma or Sketch, then migrate to the embedded display library.

Acceptance criteria
1. The prototype pairs with a phone and reliably sends play, pause, next/previous, and volume events via all three input methods.
2. Voice command latency under 500 ms for local processing or 1 s if routed through the phone.
3. Eight-hour mixed-use battery life demonstrated in a test log.
4. All source files provided: PCB Gerbers, firmware, schematics, 3-D enclosure, and UI assets, plus a short build/programming guide that lets me reproduce the unit.

If you’ve built wearables with ESP32, nRF52, or similar BLE chips and can integrate touch and voice in a slim form factor, I’d love to hear how you’d approach bringing Belflör Bloom to life." (client-provided description)
