Article summary

The article describes a project where a video wall was created using 10 old Chromebooks, which were refurbished and repurposed to display a single video across all screens. The project involved overcoming technical challenges such as synchronizing video playback and replacing the ChromeOS with a custom Linux distro. The authors used a web-based approach with socket.io to achieve video synchronization. The project took three years to complete and resulted in a unique and functional video wall.

What commenters say

  • Using old hardware for digital signage can be a cost-effective alternative to commercial solutions.
  • The project's approach to video synchronization using socket.io was innovative, but may not be the most efficient method.
  • Some commenters suggested alternative methods, such as using a single video and zooming in on different parts, but this approach may not be feasible with weak devices.
  • Accurate timekeeping is a challenging problem, and even modern NTP algorithms may not be sufficient for certain applications.
  • The project's use of old Chromebooks for a video wall is seen as a creative way to reduce e-waste and give new life to old hardware.
  • Some commenters questioned the practicality of donating old laptops to third-world schools due to logistical challenges and customs issues.
  • The project's approach to video synchronization may not be suitable for all types of content, such as interactive games or real-time animations.
  • Alternative methods, such as using PTP or hosting a local time server, may be more effective for achieving accurate time synchronization.
