Teensy-4-galvos

DIY laser galvanometer projector tools for Teensy 4.0, Max/MSP, and Python-based XY path generation. The system was developed for the Laser Dye Project, but it can also be used for engraving, PCB work, and audio-visual experiments.

Quick Start

1. Clone the repository.
2. Flash the Teensy 4.0 firmware from src/.
3. Open the Max patch in max/ and select the Teensy audio device. Or use the Python tools in python/.

Python Tools

The main GUI app is python/ld_stippling_qt.py.

Setup on Mac and Linux:

python3 -m venv .venv
source .venv/bin/activate
python -m pip install -r python/requirements.txt
python python/ld_stippling_qt.py

Windows:

python -m venv .venv
.venv\Scripts\activate
pip install -r python\requirements.txt
python python\ld_stippling_qt.py

Notes:

• Use native Windows Python for audio output; WSL may not see the laser audio device correctly.
• scipy is recommended for fast Voronoi rendering on large images.
• sounddevice is only needed for direct audio playback from the Python GUI.
