The weekend, in three acts.
Meet your team
Accepted participants can arrive alone or with friends. No experience needed. We run a team-matching session at the start so nobody builds without a team.
Build for 12 hours
Mentors are around the whole day. Optional short workshops run in parallel — drop in if you want a hand. Build an app, a game, a website, a hardware hack; anything you can finish by 5 PM.
Present & win prizes
Demo your project to a small judging panel, science-fair style. Categories include design, technical depth, creativity, and best first hackathon. Then we hand out prizes and call it a day.
What you can win.

On the t-shirt
Your logo on the shirt every attendee wears, on the website, and at the venue.

Send mentors, run a 30-minute workshop, or just sit at a table and answer questions.
Pay it forward
Free events change who gets to start building. We’re keeping this open to everyone.
