When code meets neon
Pixoo Sign Client for Ruby
Ruby dev turns a pixel sign into a home data billboard—fans cheer, skeptics side-eye
TLDR: A Ruby client makes the Pixoo 64 LED sign show animations and live home air-quality data from a simple server. The quiet comment thread links to a blog, while broader chatter splits between “cool home vibes” and “why Ruby/please use HTTPS,” highlighting a familiar debate over tools and security.
A Ruby hacker just turned the Pixoo 64—basically a bright, pixelated desk sign—into a live home dashboard. It draws rainbow animations, drops “Hello World,” and even pulls air-quality numbers like PM2.5 (tiny dust particles) from a simple server to auto-update the display. The vibe? Cozy cyberpunk meets “my living room is Times Square.” The lone comment from 0x54MUR41 drops a related blog post—and that’s all some folks needed to spin up the usual internet split. Ruby fans are swooning (“art with code!”), while pragmatists roll their eyes: why Ruby, when Python or JavaScript could do it too? The security crowd clutched pearls at plain old HTTP and a home-brew web server, warning, “please add HTTPS before your sign becomes a gossip columnist for your house.” Meanwhile, jokesters claimed “sleep 1” is the new rate limit and begged for a CO2 leaderboard. The memes wrote themselves: “Smart home scoreboard,” “PM2.5 watch,” and “If it’s red, open a window.” Whether you see it as peak maker magic or tech overkill for a blinky sign, the community’s mood was a perfect mix of heart-eyes and side-eyes—with a dash of “link me pics.”
Key Points
- •A Ruby client controls the Pixoo 64 sign, supporting animations and text rendering.
- •Examples show creating 64x64 image buffers, setting pixels, and sending animations via Pixoo::Client.
- •Text can be displayed with dev.send_text specifying coordinates, IDs, fonts, and colors.
- •PNG images are read via Pixoo::ImageBuffer.from_png and sent as animations to the device.
- •Remote data is fetched via NET_TEXT_MESSAGE from an HTTP server returning JSON with a DispData field.
