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.

ESP-Mosaico is launching today! It's a tiny, modular, composable board with a camera and a gorgeous screen. I had the privilege to build some very cool and open source demos with it, including dual amp NAM A2 guitar FX.

An AI companion. A 3D game. A guitar rig that grows as boards snap together.
Built with GEA Stack on Espressif System’s ESP-Mosaico, using TypeScript, JSX and CSS compiled to native C++.

You know and love @threejs, right?
Now ship it on a microcontroller.

You don't avoid email because you're lazy. You avoid it because a few thousand tiny decisions is a miserable job.
Unpile turns them into a handful of big ones: one click per sender, not per email.
