Frequently Asked Questions

Here are some common questions that people ask. If you have any additional questions please contact us at hackathon@osu.edu.

What is a hackathon?

A hackathon is a fun 24 or 36 hour event that brings together multi-disciplinary students with varying experience from across the nation together to create, innovate, and build a project all within one weekend. Students have access to professional mentors, workshops, and loaner hardware during the event. They also have the opportunity to showcase and demo their work projects to judges and other exposition attendees at the end of the event.

What sort of projects do people make?

All sorts of things! Previous projects have included mobile apps, websites, smart mirrors, light-up glasses, pancake printers...the possibilities are endless.

But... I don't know how to code!

Not to worry! HackOHI/O provides opportunities for first-time programmers. From workshops, to resources to mentors and teammates, you'll be sure to pick up skills over the weekend. Past that, teams need more than just coders and great projects always start with diverse teams. Everyone has some knowledge and perspective they can bring to the table.

Is it free? What about food?

HackOHI/O is free to participate in! We'll be providing you with great meals, snacks, and drinks throughout the entire event. We've got participants' food restrictions covered, too.

Who can participate?

Anyone who is a student at a university! We encourage all levels of expertise to join. Whether this is your first hackathon, or you've been to hackathons around the nation, HackOHI/O provides an opportunity to collaborate and create something amazing. All participants are expected to follow our Code of Conduct.

Anyone is welcome to attend our Sunday showcase, where our winners will present their projects. Please register if you plan on attending!

What should I bring?

Bring a laptop, a phone, some comfy clothes, appropriate chargers, and toiletries! Remember your toothbrush and paste. Leave any pre-written code at home; your projects should be started and completed at the hackathon.

What if I don't have a team?

No worries! OHI/O provides opportunities before and during the hackathon to find a team. We will soon have a team formation group on Facebook, which you will be welcome to join. We'll be posting more information on team formation events in our newsletters and on our social media accounts - be on the lookout!

How large can teams be?

All participants should be in teams of 2 to 4. We hope to encourage teamwork while keeping team sizes manageable for a 24 hour event.

Do I have to have an idea?

Nope! Many students come up with an idea at the hackathon. By talking to fellow students and coming to our pre-hype events, you'll find opportunities to join an idea that piques your interest. If you get stuck, we'll have a nice list of ideas to help you out.

Can I mentor?

Yes! We welcome individuals with knowledge and expertise in various topic areas to help mentor students at HackOHI/O. If you're interested, please fill out this form.

When will I be notified of acceptance?

We're currently in the process of reviewing all applicants and sending acceptances out in waves through the beginning of November. Stay tuned - if you've registered, you will receive an email in due time!

How are projects judged?

HackOHI/O is proud to have dozens of judges consisting of academia, industry professionals, and alumni. On Sunday, participants will share their projects with two sets of two judges, who will score the project based on several criteria: technical difficulty, functionality, intuitiveness, usefulness/impact, creativity, teamwork, and overall wow factor. Remember - the competition is only a small part of the event! The most important part is to have fun and build something amazing.

Are travel reimbursements available?

We plan on sending buses to schools in and around Ohio who have a high number of registrants. We also have a limited number of Marathon gift certificates for students who carpool to HackOHI/O from out of the Columbus area.

What is the lockdown?

For safety, no one is allowed to enter or leave the Ohio Union between the hours of 11:30 PM and 7 AM. If you'd like to leave the event for the night, please keep the lockdown period in mind.

Can I bring my desktop computer and a monitor?

Yep! Each participant's space isn't too big, but there should be enough space on the table top and ground for a desktop/monitor setup. Please note that we do not have ethernet connections available - you should come with a wireless adapter, if you do not have one already.

Wow, this all sounds so great! Who hosts HackOHI/O?

HackOHI/O is hosted by several Ohio State student organizations united under OHI/O. You can check out our other events at http://hack.osu.edu.


Without our sponsors, HackOHI/O wouldn't be possible. By joining us, you'll be in touch with some of the best developers, designers, and builders in the state. Our team will ensure that you have an incredible experience.
