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.

backtracking

It's finally time to attempt a Self-Avoiding Walk! In this video, I quickly visualize a simple JavaScript p5.js implementation of a self-avoiding walk. I then tackle the more complex problem of backtracking to find a solution to a space-filling self-avoiding walk.

Self Avoiding Walk

Choo choo! In this multi-part coding challenge, I create a maze generator using a depth-first search algorithm with recursive backtracking. The idea is to walk through a grid of cells, removing walls as we go to build a maze.
