What happens once I've entered my project?

We’ll get in touch with you by email to confirm your place. Numbers at in-person events are limited by our venue size, so we can’t guarantee that everyone who registers will get a place. Once your place is confirmed, we’ll send all the details you need for event day.

How will the judges review my project?

Judges review projects based on the criteria of Coolness, Complexity, Presentation and Communication, and Design and Usability.
