Major League Hacking 2023 Hackathon Season

November 5th-6th


What is hackPHS?

HackPHS hosts over 300 high school students from across New Jersey to collaborate, innovate, and create in a 24-hour, student organized hackathon based at Princeton High School. Whether you're a complete beginner or an experienced hacker, hackPHS will have something for you!

When and Where is hackPHS?

hackPHS will be held in the cafeteria of Princeton High School, located at 151 Moore St, Princeton, NJ. Limited parking will be available around the school. All times are tentative, but you should plan on arriving around 9:30 AM on Saturday, November 5th and leaving sometime after 2:30 PM on Sunday, November 6th.

Who pays for all of this?

hackPHS is completely free to everyone, thanks to our amazing sponsors!

What is a hackathon?

Hackathons are where creative and enthusiastic people come together to build awesome projects in a single all-nighter. With awesome workshops and incredible prizes, hackers will learn about new tech, build innovative solutions to real-world problems, and share their creation with the community, all in one event. If you are looking for a competition, a place to meet fellow hackers, or even just a place to learn how to code, hackathons are for you. If you want to learn more, see the MLH Hackathon FAQ.


Unfortunately, this event is for high school students only. If you are no longer a high schooler and would like to help out, consider becoming a mentor. Email us at for more info on this!

Apply by going to our registration link. We will be doing admissions on a first-come first-serve basis, so apply ASAP!

Sign up here to be a chaperone or email for information about mentors and judges!

Free food and drinks will be provided during the hackathon, including options for people with dietary restrcitions. If you ever want to sleep during the hackathon, we'll have dedicated quiet sleeping areas for y'all to catch some Z's. Electrical outlets will also be available throughout the cafeteria for all your charging needs. This year we will not be providing a hardware lab, so make sure to bring any hardware you want to use for your project.

Make sure you’re ready to spend 24 hours away from home. Basically, bring a sleeping bag, extra clothes, a toothbrush, and anything else you might need to feel comfortable for a long period of time. Also, please bring anything you need for your project such as a laptop, laptop charger, and hardware.

Attendees will be required to be either fully vaccinated or provide negative test result from within 48 hours of the event. Vaccination cards should be uploaded during registration, and negative test results should be shown during check-in at the event. More details about Covid protocol will be updated closer to the event based on the situation of the pandemic.

Teams of up to 4 people are encouraged (though not mandatory) - if you already have a team, you can form your team when registering for hackPHS, but teams won't be final until submissions. If you don't have a team before the event, don't worry! At the beginning of the event, there will be a team building workshop, which will be a great way to meet other enthusiastic people and even make new friends.

No matter if you're a first time hackathon attendee and have no idea what to do (everyone was a beginner once), or are an experienced hacker who wants to give back to the community, it is a good idea to join our Facebook event and follow us on instragram @hackphs! In addition to all the important announcements and information about the event, you'll be able to find others to guide you through the hackathon process and help you develop something awesome.

All hackers must abide by Major League Hacking's Code of Conduct. TL;DR - all hackers should respect one another. Hackers also must abide by Princeton High School rules while on PHS grounds.

hackPHS hopes to emphasize learning and collaboration more so than competition - nonetheless, there will be awesome prizes to be won for some of the best hacks made during the event! The full prize list will be released later - make sure to follow us on social media to find out when!

While you can learn a great deal in the process of building an ambitious project in such a limited time frame, we also plan to offer many introductory workshops (around 1 hour each) during the event, for those new to software and/or hardware engineering. Specific topics will include Python, Web Development, and Circutry, among many others - check our schedule for the full list!
