ESP32 VOICE ASSISTANT

Finch desktop
voice assistant.

Finch is an Alexa-style desktop assistant with custom hardware. A custom ESP32 board listens through a microphone, sends the request to a Python service, then plays the spoken answer through its speaker.

The project includes PCB design, audio, Wi-Fi, firmware and an enclosure. The first version works; a second is being developed with more storage and additional interface features.

TEN-MINUTE VIBRATION REMINDER

Rechargeable
haptic reminder.

A nonprofit wellness client needed a discreet, regular tactile reminder. I built a compact rechargeable device that gives a short vibration every ten minutes.

The PCB, battery, motor and printed enclosure fit into a roughly 1 × 2 inch package. Low-power firmware lets the controller sleep between reminders, with week-plus battery life as the design target.
