- Role
- Built the firmware and interaction model for a constrained live-data device.
- Outcome
- Market state became available through a dedicated physical dashboard.
- Evidence
- Public repository and device visual.
- Context
- A physical device needed live data, touch, settings, and first-boot setup.
- Built
- Firmware, WiFi QR setup, rendering zones, touch gestures, audio alerts.
- Stack
- ESP32-S3, LovyanGFX, PlatformIO, APIs, NVS, I2S audio.
- Proof
- Public GitHub repo.
case notes
A bounded product surface.
Each experiment is useful because it makes a constraint concrete: device limits, operator visibility, answer-engine ambiguity, or agent review.
