Share Your Idea: Lightning Talks at OpenFest 2025

This year, OpenFest is once again giving everyone a chance to take the stage with a Lightning Talk! These are brief, 5-minute presentations that offer you the opportunity to share your project, discovery, or idea with the wider community.

Registration and Deadlines:

  • How to Sign Up: You can register for a Lightning Talk at the fest’s Reception Desk.
  • Deadline: Registration closes 1 hour before the scheduled start of the session.

Technical Requirements:

  • Every speaker must bring their own laptop (if they plan to show any visuals).
  • The laptop must have an HDMI output.
  • If you have any concerns about your laptop’s compatibility with our projection system, please reach out to the volunteers to arrange a preliminary test.

Organizational Details:

  • We kindly ask everyone who has signed up to be present in the designated hall at least 1 hour before the session begins to ensure the smooth running of the event.

We look forward to hearing your inspiring and concise presentations!
