Would you try a DIY project to repurpose your old electronics into a home display?

Developer Kevinclayland has released the open-source WalCalToDo project on GitHub, enabling users to transform a Raspberry Pi and spare monitor into a real-time digital wall calendar. The software integrates directly with Google Calendar and Microsoft To-Do to mirror scheduling updates as they occur.

Why it matters

The tool offers a low-cost method for businesses to repurpose existing monitors for communal office scheduling. This approach leverages internal hardware to improve team visibility of upcoming tasks and project deadlines.

The project requires a Raspberry Pi 3B or newer hardware to function, and data indicates that 90% of tech enthusiasts already own the necessary spare monitors for the setup.

The players

Kevinclayland

An independent software developer who released the WalCalToDo project for hardware repurposing.

GitHub

A Microsoft-owned platform used by developers to host and distribute open-source software code repositories.

The details

The system works by linking the Raspberry Pi to a display, which then reflects changes made on mobile devices in real time via the companion app. Users manage privacy settings and account configurations through the application, ensuring that sensitive schedules remain protected. The project is currently hosted on GitHub for public access.

Timeline

Market Landscape

This project follows a growing trend of utilizing the Raspberry Pi 3B and newer models to avoid the high cost of dedicated enterprise display hardware. It highlights a shift toward custom, software-defined office infrastructure for small teams looking to optimize utility.

Business owners should review their existing stock of idle monitors for potential deployment as visual team task boards. Evaluate the security requirements of your calendars before syncing with third-party software tools.

The takeaway

Repurposing idle hardware is a low-cost strategy for enhancing team visibility of shared workflows. Review your inventory of monitors and single-board computers to identify opportunities for low-cost internal dashboarding.
