Muse Gadgets
Muse gadgets are open source devices you build yourself. Program an
off-the-shelf ESP32 board or set up a Raspberry Pi with our device SDKs, then
connect Muse to your displays, buttons, sensors, actuators, and whatever else
you've got lying on your workbench.
We open sourced the SDKs and firmware here. It's built by hackers, for hackers,
just for fun. Side effects of tinkering may include bricked boards, voided
warranties, brownouts, or bankruptcies. Proceed at your own risk!

| ESP32 Device SDK | Connect your ESP32 board to Muse through our open source SDK. Throw in a screen to show images, add audio in and out, or wire up other sensors. |
| Linux Device SDK | Turn that spare Raspberry Pi or Linux box into a Muse gadget. Hack in your own commands to let Muse handle sysadmin chores or your Home Assistant setup. |
| Muse Gadgets Test (iPhone) | Stream your phone's camera, or a clip, to an ESP32 gadget's screen over Wi-Fi: H.264 or VP8 decoded on the board, 30 fps on the round 466 px boards. protocols/VIDEO.md explains how. |
Before you flash or pair a gadget, get an
SDK token and review the
Gadget SDK Terms. Every gadget needs a
token to pair.
ESP32 and Linux gadgets pair with the Muse app on iOS and Android, via
Settings > Devices. Turn on Developer mode there first, then look for devices
prefixed with "MuseGadget".
Each directory has a README.md to get started and an AGENTS.md for coding
agents like Muse Code.
For battery-input power profiling, see the porting recipe.
The opt-in diagnostic core is board-neutral; boards supply its hooks and state
matrices, and power_sweep.py drives the
USB-free sweep. The isolated diagnostic does not pair or need an SDK token;
fixture safety and explicit hardware authorization still come first, as the
PPK2 rules describe.

Muse Gadgets Test's sample clips aren't in this repository: the app fetches a few
seconds of the Blender Foundation's open movies (CC BY 3.0) when one is
played, and shows their credits.
