Dublin Hacx is a free, 12-hour hackathon for high school students in the Bay Area, taking place on October 3, 2026, at the SAP Office in San Ramon. Participants bring an idea and have 12 hours to build it, with no specific theme, and then demo their project.

By Hack Club community
Dublin Hacx is the inaugural hackathon hosted by the Emerald Hacking & Coding Club, an event specifically designed by students for students. The 12-hour event, running from 10 AM to 10 PM, encourages participants to develop an idea from conception to a working prototype within a single day. It aims to foster hands-on building experience and provide a supportive environment for both novice and experienced coders. The hackathon is completely free to attend and will accommodate 170 high school students from across the Bay Area. It emphasizes practical application and creation, encouraging participants to focus on building a functional project rather than just presenting an idea. The event provides mentors and workshops to guide participants throughout the day. The schedule includes dedicated time for building, along with check-in, an opening ceremony, provided meals (lunch and dinner), workshops on various topics like web, AI, and hardware, and a judging session. The day culminates in an awards ceremony. The event is hosted at the SAP Office in San Ramon. There is no specific theme for Dublin Hacx; participants are encouraged to pursue any project they are curious about. The main constraint is the 12-hour timeframe, pushing participants to ship a working demo by 8 PM. This open-ended approach allows for maximum creativity and personal investment in the projects.
Participants should bring any idea they are curious about and build it into a real, running project within the 12-hour timeframe. There are no specific themes, required tracks, or boxes to fit inside. The project should be a functional demo by 8 PM, not a slide deck.
