USB Relay Kernel Driver

A Linux kernel driver and CLI for USB relay boards.

Impact

  1. 01Kernel module that binds to the board's FTDI FT232R chip and exposes each board as /dev/usbrelayN, with a one-byte mask ABI that drives all 8 channels.
  2. 02Enables FTDI bit-bang mode with vendor USB control requests, so all 256 output states fit in a single byte write.
  3. 03Handles hot-plug through probe/disconnect, endpoint discovery, and bulk transfers with 1 s timeouts.

Tempr

Swipe-to-discover music, built on Spotify.

Impact

  1. 01I placed 2nd in the GT Hacklytics Entertainment track, shipping a React Native app with Spotify sign-in in 36 hours.
  2. 02I built a Tinder-style, short-form music discovery feature as the base for a vector-similarity recommendation engine over Spotify song vectors.
  3. 03The team built multimodal Gemini pipelines that turn a text prompt or photo into a playlist through the Spotify API.

The Workout prompt weights the five features Energy 0.90, Danceability 0.75, Tempo 0.71, Acousticness 0.05, Valence 0.70; their sum is the song vector.

FeaturesSong vector

A prompt weights each feature; their sum is the song vector. Illustrative values.
