Featured Challenge:
#188 — Voice Chatbot

In this coding challenge, I build a conversational voice chatbot entirely in the browser with p5.js. I combine three pieces: speech-to-text with OpenAI's Whisper model, text-to-speech with Kokoro TTS, and a "brain" for the bot. I also explore the transformers.js pipeline API and the Web Audio API. For the bot's brain, I start with a simple ELIZA-style therapist, then incorporate a RiveScript number-guessing game, and finally a local LLM.

In this coding challenge, inspired by Numberphile I visualize "sandpiles" with Processing (Java).

Langton's Ant is a cellular automaton that starts off with simples rules but takes on complex emergent behavior.

In this coding challenge, I attempt to code Conway’s Game of Life cellular automata simulation in JavaScript using the p5.js library.
