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.

physics engine

An attempt to implement the basic mechanics of Angry Birds in JavaScript using p5.js and the matter.js physics engine.

Angry Birds with Matter.js

In this two part challenge, I cover beginShape(), endShape(), and texture(), TRIANGLE_STRIP, QUAD_STRIP, and more. I combine these geometry functions with the Toxiclibs physics library to simulate a waving flag (with a unikitty image texture!)

Texturing Cloth Simulation

I love all things random and chance so why not make a Plink simulation with the matter.js physics engine and p5.js!
