TL;DR
A public Ruby client, pixoo-rb, provides tooling to control the Pixoo 64 LED sign from Ruby code. The repository includes utilities for drawing animated frames, sending text and images, and fetching remote data to display on the sign.
What happened
The pixoo-rb repository, published by user tenderlove, provides a Ruby client for the Pixoo 64 LED sign. The project exposes utilities such as an ImageBuffer for programmatically building frames, methods to send animations and text to a discovered device, and a helper to load PNG files into the buffer. The README includes example code that generates animated patterns, sends multiple frames as an animation, places text at specified coordinates and fonts, and demonstrates reading sensor values from an HTTP endpoint to display live data on the sign. The codebase is hosted publicly on GitHub under an Apache-2.0 license, is written entirely in Ruby, and shows modest community interest (6 stars at the time of capture). The repository contains a README, gemspec, and basic project files; the latest commit message in the log is "fix deps."
Why it matters
- Provides a Ruby-native way to control a Pixoo 64 LED matrix, lowering the barrier for Ruby developers to integrate signage into projects.
- Supports both animated frame sequences and static text/images, enabling dynamic visualizations and simple dashboards.
- Built-in support for fetching and displaying remote data means the sign can be used as a live sensor or status display without extra glue code.
- Distributed under Apache-2.0, allowing use and modification in open-source and commercial projects subject to the license terms.
Key facts
- pixoo-rb is a public GitHub repository owned by tenderlove.
- The client targets the Pixoo 64 sign and is implemented in Ruby (100% language share).
- Provides an ImageBuffer abstraction for building frames and includes utilities (e.g., rainbow_color) for drawing.
- Can send animations via dev.send_animation and text via dev.send_text, and can load PNGs with ImageBuffer.from_png.
- Includes a mechanism to create network-based display items that fetch text from an HTTP endpoint and show the returned value on the sign.
- Repository files include README, LICENSE (Apache-2.0), Gemfile, pixoo.gemspec and basic test and lib folders.
- At the time of capture the repo had 6 stars, 0 forks, 0 watchers, and one tag under Releases.
- Latest visible commit message in the repository history is "fix deps."

Quick glossary
- Pixoo 64: An LED matrix sign device used for displaying text, images and animations on a 64×64 panel.
- ImageBuffer: A programmatic buffer for composing individual pixel frames before sending them to a display device.
- Apache-2.0: A permissive open-source license that allows use, modification and distribution with attribution and a grant of patent rights.
- HTTP endpoint: A URL on a server that returns data over HTTP which can be consumed by clients for display or processing.
