Contrib Cal
Open-source, hackable, and judging you silently.
A glowing, hackable GitHub calendar that transforms your coding activity into a physical light display.
3D-printed, NeoPixel-powered guilt trip:
- Turns your GitHub activity into a glowing desk monument
- Built on Raspberry Pi Pico W with WiFi connectivity
- Pulls your real GitHub data (or fakes it—we won't tell)
Key Features:
- Lights up with every commit—green for wins, red for shame (fully customizable)
- Runs custom MicroPython firmware (hackable like real code)
- 3D-printed enclosure (sleek or janky—your choice)
Perfect for developers who:
- Want to flex their 28-day streak in the physical world
- Need a blinking reminder when commits are missing
- Miss the dopamine hit of hardware hacking
See your commit streak—in real life
