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.

Learn to create your own climate spiral using p5.js and temperature data. Originally designed by the climate scientist Ed Hawkins, the climate spiral is a visual representation of the changing temperatures over time, illustrating the urgent need to address climate change.

In this coding challenge, I visualize the Recamán’s number sequence using the p5.js library and go on to generate a series of musical tones using p5.js sound.

In yet another “Pi Day” coding challenge, I attempt to generate a pdf “Book of Pi” with the first 10 million digits of Pi mapped to color. Processing (Java) is used for this project.

In this challenge, we build a word counting (concordance) application, and visualize the frequency of each word using variable font size! We also implement the TF-IDF algorithm
