01 / About
What is
hackPHS?
hackPHS hosts over 100 high school students from across New Jersey to collaborate, innovate, and create in a 24-hour, student-organized hackathon at Princeton High School. Whether you're a complete beginner or an experienced hacker, hackPHS will have something for you!
You don't need a perfect idea or years of experience. Just bring a laptop, some curiosity, and a willingness to try something new.
Open-source hackathon
hackPHS is built around open source. Hackers are encouraged to publish their code, use open-source tools, and share what they learn. See what hackers built last year.

09 What can I learn?
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. Last year's topics included Python, Web Development, and Circuitry, among many others—check our schedule (coming soon) for the full list!
