Stories
Not organized by technology — organized by story. Here's what actually got built and why.
Problem: Drift and track drivers rely on feel, not data. Off-the-shelf telemetry either doesn't exist for this use case or locks the data behind a cloud subscription.
Approach: Build a self-contained unit — ESP32-S3 for real-time sensor fusion, Pi Zero 2W for the dashboard and storage, GNSS and CAN bus for full context. Everything runs locally.
Prototype: This became the third iteration of the Aven'helm hardware architecture — proving out IMU fusion (Madgwick MARG) and the LVGL touchscreen UI that carries directly into the helmet platform.
Status: Final components inbound. Firmware and dashboard architecture proven on earlier prototypes.
Problem: The idea that started this: what would it feel like to control your world with a flick of a finger — the smart home, the car, the motorcycle — without reaching for a phone or a remote. Camera-based tracking can't do it discreetly and fails outside a fixed volume.
Constraints: Needed to be wearable all day, wireless, and accurate enough to distinguish individual finger movement from surface signal alone.
Architecture: Surface EMG + HRV sensing via XIAO nRF52840 Sense, INA333 instrumentation amp, OPA2333 filtering, wireless charging, hermetically potted enclosure for a silver-mesh bracelet form factor.
Status: In development. Applications span VR control, accessibility input, and smart home gesture control.
Every project here started as someone's specific, unglamorous problem.
