Logic & Light
Logic & Light is Mike Chiou's portfolio of independent projects, including 4000 Weeks, RHz HRV Biofeedback, Vitality Arc, and ToneLatch. Each project keeps its own voice, destination, and pace while this homepage stays quiet and focused.
Selected work
The common thread is not subject matter. It is the way the work is made: clear framing, distinct identities, and enough care that each project earns its own home instead of being buried inside a generic portfolio dump.
Poster-like planning for seasons, milestones, and a finite number of weeks.
Current project
A poster-like life-in-weeks planner that turns finite time into something editable and easier to act on. Reflective rather than productivity-first, with its own editorial voice.
Guided breathing, external sensors, and local-first HRV sessions.
Current project
A precision-oriented Android HRV biofeedback app for resonance breathing training. More technical and sensor-driven than a generic breathing timer, with local-first data handling and a live Google Play release.
Wearable-friendly inputs, uncertainty bands, and a time-scrubbable future healthspan view.
Current project
A healthspan and physical-capacity explorer built around noisy, real-world inputs. It turns fitness, strength, body composition, and wearable signals into future-facing lower, base, and upper trajectories instead of a single fake-precise answer.
Keep the film simulation. Add real HDR highlight data from the RAW.
Current project
A macOS Ultra HDR JPEG app for Fujifilm X100 and Ricoh GR shooters who want to preserve their SOOC film simulation look while adding real HDR highlight data from the RAW file.
