A new open-source gadget is bringing Formula 1 racing info to your desk, and it runs on an ESP32 e-ink display. As Hackaday reported, the project, built by “mazur8888”, combines the popular ESP32 microcontroller with a tri-color e-ink screen to show race standings, upcoming race schedules, and pole-position information.
What the ESP32 e-ink display does
- The device refreshes its display about every 30 minutes, pulling in updated data on team rankings and race info. While not real-time, it’s perfect for casual fans who just want the big picture.
- It puts the ESP32 to work hard: besides driving the e-ink screen, it also hosts a small web dashboard for setting things up, updating software (Over-The-Air updates), and adjusting preferences.
- The whole device uses a 2.9-inch tri-color e-ink display in a 3D-printed case, making it compact, lightweight, and desk-friendly.
Why e-ink makes sense here
This ESP32 e-ink project isn’t just another weather display. E-ink offers clear advantages:
- Energy efficient: Unlike regular screens, e-ink only uses power when the image changes.
- Eye-friendly: No bright backlight or flicker — just sharp, paper-like text.
- Customizable: Since the project is open source, anyone can tweak the code or design to suit their own needs.
Part of a bigger DIY movement
The Formula 1 tracker is just one of many creative uses of ESP32 e-ink displays. Makers are using them for:
- Weather dashboards that refresh only when needed to save power.
- Smart photo frames that show maps, artwork, or family reminders.
- Minimalist clocks and calendars that look more like paper than screens.
This trend shows how the ESP32 microcontroller and e-ink technology pair well for low-power, always-visible information displays.
What could be better
- Update speed: A 30-minute refresh is fine for standings, but not enough for live lap times.
- Power options: While e-ink is efficient, the ESP32 still needs a steady power source.
- Screen size: The 2.9-inch display is neat but limited — larger screens could show more detail.
Bottom line
The ESP32 e-ink display makes racing stats fun, stylish, and energy-friendly. Whether you’re a Formula 1 fan, a DIY tech hobbyist, or just someone who likes sleek gadgets, this project shows how open-source hardware and e-ink technology are reshaping how we view everyday information.
