Badges, beef, and WiFi
Hacking the WiFi-enabled color screen GitHub Universe conference badge
Free GitHub badge with a color screen sparks a spicy fight: ‘real Raspberry Pi’ or just a tiny chip
TLDR: GitHub’s hackable badge is a fun, WiFi-ready mini device with games and a profile screen, but the crowd pounced on a “full Raspberry Pi” claim—correcting it to a tiny microcontroller. Excitement mixed with nitpicks over specs, security quirks, and an AI-written README—because even swag stirs tech drama.
GitHub Universe handed out a WiFi, color-screen badge you can actually hack—think mini game machine on a lanyard—and the internet instantly turned it into a spec war. One sharp-eyed commenter flagged the claim of a “full Raspberry Pi,” insisting it’s actually an RP2350B MCU (a tiny microcontroller unit), not a full computer. The author updated the language, but the nerd police were already out in force, debating what counts as “real Pi” versus “Pico vibes.” Meanwhile, the rest of the crowd is busy grinning: it runs MicroPython (a light version of Python for small gadgets), plugs in via USB‑C, and shows your GitHub avatar and stats right on your chest—cue jokes about wearing your follower count like a name tag. The badge’s built‑in games (flappy clone, digital pet, etch‑a‑sketch, IR scavenger hunt) got love, while the preloaded WiFi details sparked playful side‑eye about “shipping secrets.” The Bluetooth keyboard idea drew skepticism, with people riffing on the five-button life: Up, Down, A, B, C, and vibes. Bonus drama: Simon leaned on an AI tool to whip up a README—half the thread cheered “AI to the rescue,” the other half groaned “LLM wrote my homework.” Links for the curious: docs and the README.
Key Points
- •The GitHub Universe badge runs on a Raspberry Pi Pico microcontroller with a color screen, WiFi, Bluetooth, battery, buttons, and an IR sensor.
- •All software is written in MicroPython; connecting via USB-C mounts the device as a drive for direct code edits.
- •Default apps include games, a drawing app, an IR scavenger hunt, a gallery, and a badge app that can display a user’s GitHub profile info.
- •Setting up the badge app requires editing secrets.py to confirm WiFi and add a GitHub username, then rebooting.
- •The codebase is organized under an apps/ directory, with the home menu in apps/menu/, and new apps can be added by editing the menu.
