Love it, @stolinski! If you want to write in TypeScript and using web technologies and get super fast performance, you might want to check out github.com/geastack.

github.com GeaStack GeaStack has 26 repositories available. Follow their code on GitHub.

Building a whole music creation platform on my GitHub Universe Badge. 3d printed a case that slides on for the speaker.

Snap on another board and make room for more sound!

A guitar pedalboard that grows with your ideas. Snap on another board and make room for more sound!

Built on Espressif’s ESP-Mosaico, this setup starts with guitar effects and amp modelling on a single device. Add more boards and the app spreads the signal chain across them. With four, you can run two amp models in parallel and blend their tones.

GEA brings the touchscreen interface to life with TypeScript, JSX and CSS compiled into native code.

The boards share audio wirelessly over ESP-NOW, while you tap through effects and explore different presets. Explore GEA: geastack.com

Touch. Play. Watch it respond.

This little AI companion can talk with you about what its camera sees.

Espressif’s ESP-Mosaico brings together a touchscreen, microphone and speaker, with a camera attachment giving Axel a view of its surroundings. Show it an object, ask a question, and keep the conversation going.

The app is built with GEA in TypeScript, JSX and CSS, compiled into native code for the device. It connects to OpenAI’s Realtime API for the conversation, bringing voice, vision and a touch interface together in a small piece of hardware.

There’s a whole little river running on this microcontroller.

In Lantern River, you guide a paper boat through a 3D world, collecting lanterns and trying to stay clear of the rocks. It looks rather peaceful until you start hitting them.

The game runs natively on Espressif’s ESP-Mosaico, with its ESP32-S31 processor and 2.16-inch AMOLED touchscreen. Built using GEA, the TypeScript, JSX and CSS app compiles into C++, putting familiar web development tools to work on a handheld device.
