Open source hardware for Muse

Muse Gadgets is an open source hardware project for connecting self-built devices to Muse. Instead of selling a single fixed gadget, it provides device SDKs and firmware that makers can use with an off-the-shelf ESP32 board, a Raspberry Pi, or another Linux computer.

The resulting gadget can combine Muse with physical interfaces such as displays, buttons, microphones, speakers, sensors, and actuators. Builders start with an SDK token and a project idea, configure the device, and customize the hardware or software for a particular interaction. The project also publishes example builds and invites contributors to share their designs through the community Discord and GitHub.

Capabilities and components

Open source SDKs and firmware

The open source device SDKs and firmware provide a starting point for building and customizing a Muse gadget.

ESP32 device support

Program an off-the-shelf ESP32 board to connect it to Muse, then add compatible peripherals such as displays, audio input and output, or sensors.

Linux device support

Use a Raspberry Pi or another Linux box as a Muse gadget and add custom commands for tasks such as interacting with Home Assistant or handling system administration chores.

Peripheral and interface projects

Example projects cover screens, push-to-talk controls, speakers, microphones, buttons, LED status indicators, color e-ink displays, and other device components.

Token-based pairing

SDK tokens are added to the SDK configuration so a self-built gadget can pair with the Muse app.

Apache 2.0 source license

The project is published under the Apache 2.0 license, allowing makers to inspect the source and contribute improvements back to the community.

Example projects and practical uses

Home automation and Linux tasks
Use a Raspberry Pi or Linux box to let Muse interact with Home Assistant or run custom system administration commands.
Dedicated voice controls
Build a compact voice interface with push-to-talk, a microphone, and a speaker, using example hardware such as the Waveshare ESP32-S3-Touch-AMOLED-1.75CA or Home Assistant Voice Preview Edition.
Status screens and information panels
Add a display for status, images, briefings, reminders, shopping lists, or other information. The examples include color screens, a 1.75-inch AMOLED display, and an e-ink display.
Desktop and portable interfaces
Create a small desk or handheld companion with a button, screen, and audio output so Muse can respond physically rather than only through the app.
Custom hardware experiments
Develop a new board integration or modify an existing project, then publish the source and a short demonstration for other community members to build on.

Pros and Cons

Pros

Supports both ESP32 boards and Raspberry Pi or other Linux-based builds.
Lets builders choose physical outputs and inputs, including displays, buttons, audio hardware, and sensors.
Provides open source SDKs and firmware under the Apache 2.0 license.
Includes example projects and a community workflow for sharing source code and build ideas.

Cons

Hardware components and assembly are left to the builder, so the site does not present a single ready-to-use device.
The SDK is intended for personal tinkering, is not a supported product or developer platform, and may change, break, or stop functioning without warning.
An SDK token is required, and each token supports only a limited number of devices.

FAQ

What are Muse Gadgets?

Muse Gadgets are open source devices that you build yourself. The site describes two SDK paths: an ESP32 Device SDK for compatible ESP32 boards and a Linux Device SDK for a Raspberry Pi or another Linux box.

How do I get started?

Start by obtaining an SDK token, selecting a project idea or supported board, and adding the token to the SDK configuration. The token lets a gadget pair with the Muse app.

What can I connect to Muse?

The ESP32 SDK can connect a board to Muse and support additions such as a screen, audio input and output, or other sensors. The Linux SDK can turn a Raspberry Pi or Linux computer into a gadget with custom commands.

Are the SDKs intended for production use?

An SDK token is required for gadgets built with the Muse Gadget SDK, and each token can be used by a limited number of devices. The SDK is intended for personal tinkering rather than a supported product or developer platform, and may change or stop working without warning.
