Heartbeat-Synced Glowing Heart

A Wi-Fi IoT gift that pulses to a real heartbeat, with a Claude pipeline that turns biometric data into mood-based light.

Heartbeat-Synced Glowing Heart

Overview

A Mother's Day gift built end to end: an ESP32 microcontroller drives WS2812b LED strips to simulate a heartbeat, a companion app runs an integrated Claude AI pipeline that analyzes incoming heartbeat data, and the user can retune the device's light to reflect different moods. Housed in a hand-finished, laser-cut acrylic box with an SLA 3D-printed transparent heart.

Highlights

  • 01Engineered a custom, Wi-Fi-enabled IoT device on an ESP32 with a breakout board and WS2812b LED lightstrips to simulate a live heartbeat.
  • 02Built a companion app with an integrated Claude AI pipeline to analyze heartbeat data and let the user customize lighting to reflect moods.
  • 03Fabricated a custom casing with Makerspace tools — laser-cut white acrylic bonded to a hand-finished SLA 3D-printed transparent heart.
