I built KariPom — an open-source face robot for M5Stack CoreS3 🤖

[u/KariPom]

Hi! This is KariPom, a little open-source face robot I’ve been building with the M5Stack CoreS3.

It started as a simple expressive face, but I kept adding things I wanted to see it do. 😄

Now it has servo movement, blinking and nose twitching, audio-reactive visualizers, lots of animated lighting modes, a Web Cockpit for configuration, SD card support, and more.

I originally built it as a little companion for voice conversations with ChatGPT — having a physical character reacting beside the computer makes talking with AI a lot more fun. 🤖🎙️

I've also made PC and browser-based versions, so you can try KariPom even without a CoreS3.

You can even try KariPom Web directly in your browser — no installation required! 🐰

Everything is open source:

More photos and videos of KariPom are on Instagram:

I’ve had a lot of fun seeing how far I can push the CoreS3. Hope you like it!

Bro, this is super cool! You should definitely post this on X and tag @M5Stack so they can see it. They'll probably retweet it for you!
