A Raspberry Pi-powered live train station sign (balena.io)

Article summary

The article describes a DIY project to build a live train station sign using a Raspberry Pi Zero, an OLED display, and a 3D printed case. The project uses live data from the National Rail Enquiries OpenLDBWS API and can be easily deployed and configured using balenaCloud and Docker. The sign displays the departure times and other information in a format similar to the traditional dot-matrix LED displays found in UK train stations. The project's code and documentation are available on GitHub.

What commenters say

• Some commenters think that using a Raspberry Pi for this project is overkill and that an ESP8266 or ESP32 would be sufficient.
• Others argue that the Raspberry Pi's ease of use and familiarity make it a good choice for DIY projects like this.
• The project's use of live data and traditional display format is seen as a nostalgic nod to old train station signs.
• Some readers are interested in modifying the project to display information for London Underground stations or other types of data.
• There is a discussion about the feasibility of building a split-flap display, a type of mechanical display used in old train stations, using modern materials and technologies.
• Some commenters share their own experiences with similar projects, such as building a split-flap display or using a Raspberry Pi for other DIY projects.
• The use of Electron for cross-platform software development is compared to the use of Raspberry Pi for DIY projects, with some arguing that both serve a purpose in simplifying development and deployment.
