LexHack is a hackathon for high schoolers of all programming abilities. It’s free, all day (12 hours), and equipped with hackable hardware (e.g. Arduino, Raspberry Pi), great prizes, tons of swag, delicious food (all meals provided!), and mentors to help you build your project. It’s Saturday, November 3rd in commons 1 and 2 of Lexington High School. Sign up to be a hacker here.

What is a hackathon? A hackathon is an engineering and coding event where students collaborate to build or program entire projects. Come with a team of friends, or create a team at the event and make new ones. LexHack’s mission is to spread the love of programming and innovation to everyone by making our event as accessible as possible.

Register as a hacker here. If you want to use some hardware and don't have what you need at home, please indicate that on the hardware section. Tell us what you're looking for, and we'll see if we can provide it at the event.

Register as a mentor and/or a judge here. Sign up for as long as you are available! If you are available during the night, you can also sign up to judge -- we will later contact you if you are chosen as a judge.


Who can attend?

Any high school student can attend. If you're in middle school or are otherwise unsure of your eligibility, please email us.

What if I have no programming experience?

No problem! LexHack is a great way to learn. We even have prizes exclusively for beginners. You can sign up for a free coding workshop graciously hosted by our sponsor, Penguin Coding School, and our mentors can help you get started making a basic web app with our start guide. If you need ideas, you can look at this comprehensive list of project ideas to help get you started.

How much does LexHack cost?

Absolutely nothing! Unfortunately, we cannot offer travel reimbursements at this time, but feel free to contact us for travel advice.

What do I bring?

Bring a laptop, laptop charger, the signed waiver (which will be sent out in an email before the event), and anything else you want to hack with. All meals and snacks are provided free, so you won't need to bring any. If you require special food accommodations, or don't have a laptop you can bring, please contact us.

How do I make a hardware hack?

Read about available hardware and usage guidelines here. You will also have to reserve a piece of hardware in advance, through the registration form.

Do I need a team for LexHack?

Nope! You can join with others at the event.

How big can teams be at LexHack?

Teams must be four people or fewer.

How does judging work?

You will have the chance to present your project to a panel of professionals, and receive feedback on your work. Projects will be judged on their creativity, effectiveness, and technicality.

How can I help LexHack?

You can sign up as a mentor here, or as a volunteer by sending us an email. Interested in sponsoring? Check out our sponsor information here.
