The Ohio State University's
annual makeathon.


March 5th - March 7th, 2021

Welcome to Make

On March 5th, join us at MakeOHI/O—the Ohio State University's largest makeathon—for a weekend of building and creating real projects with awesome people. Over 150 undergraduate and graduate students will design, build, and demonstrate projects to a live audience of students, faculty, and representatives from tech companies. MakeOHI/O is put on by OHI/O, a student-led organization that aims to build and foster the tech community at Ohio State University. This year, BioHack and MakeOHI/O will be partnered!

Meet other passionate, fun and creative students from OSU and universities across the nation. Our industry partners are also sending professional developers, designers, marketers, and hustlers to provide mentorship. If you're interested in participating, all attendees must adhere to our Code of Conduct.

Project Showcase

Meet great people.

Learn something new.

Build something amazing.


Here are some common questions that people ask. If you have any additional questions, please contact us at

What is a makeathon?

A makeathon is similar to a hackathon. Both are events where participants build awesome projects from scratch in just a few short hours. The difference between a MAKEathon and a HACKathon is that we are encouraging projects to be maker-oriented, and therefore physically making something!

Since Bio-Hack is a part of MakeOHI/O, am I locked into doing a bio-related project?

Nope, you are free to explore any topic you find interesting. We have partnered with BMES and BioHack this year to offer more choices and bring greater attention to Bio-related topics. Feel free to create any project you are interested in, Bio related or not.

Who can participate?

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

I want to apply for MakeOHI/O! What's the timeline?

Registration will go live January 15th and continue until March 4th. If you want to be eligible to build a hardware kit, you must register and have a team before February 11th. If you have any questions, feel free to reach out to

What sort of projects do people make? How can I get hardware?

Teams make all sorts of things! Previous projects have included mobile apps, websites, smart mirrors, light-up glasses, pancake printers...the possibilities are endless. Hardware will be made available to teams via a kit builder that opens February 12th at noon. Challenges and prizes will be announced simultaneously to give teams an opportunity to select the most appropriate hardware. Teams will be able to build a kit from our list of hardware and pick it up the week before the event, free of charge! Anyone within a 30 mile radius of OSU will have to pick up their kit. If you are outside 30 miles, contact to make additional arrangements.

Is this event free?

MakeOHI/O is free to participate in! We want all students to have an opportunity to work on projects with hardware, which is why we’re also providing free hardware kits this MakeOHI/O.

Do I need a team?

All participants should be in teams of 2 to 4, but don't worry if you're coming in without a team. OHI/O provides opportunities before and during the makeathon to find a team. Team formation will be ongoing in the Discord server up to the event. We will post more information on team formation on our event website and in Discord but step one is to register for participation.

Do I have to have an idea before attending/registering?

Nope! Many students come up with an idea while at the makeathon or by addressing one of our proposed challenges. By talking to fellow students you'll find opportunities to brainstorm ideas that pique your interest. you get stuck, we'll have a nice list of ideas to help you out. This year, we recommend discussing possible ideas with your team before kit building opens so that you have a better idea of what hardware to choose for your kit.

Can I mentor?

Yes! We welcome individuals with knowledge and expertise in various topic areas to help mentor students at MakeOHI/O. If you're interested, please contact us to find out more information!

What does it mean to join a team in the registration portal?

Upon verifying your account, you can pick a team to join in the application Please note that everyone on the team must join it individually! You must be on a team to participate and Hardware kits are only distributed 1 per team (of 2-4 students).

How are projects judged?

MakeOHI/O is proud to have dozens of judges consisting of academia, industry professionals, and alumni. On Sunday, participants will create a 2 min video demonstration of their project and submit it for judging. More details on how the submission process works will be given closer to the event. Remember - the competition is only a small part of the event! The most important part is to have fun and build something amazing.

Are any projects not allowed?

For safety reasons, projects that intend to interface with the 120V AC mains in any way other than direct power are discouraged. Even something as small as a relay controlling a lamp being on could be hazardous with exposed wires. For similar reasons, projects involving high voltage such as Tesla coils, jacob’s ladders, or plasma speakers are discouraged. If you are unsure if your project will be allowed, please ask! We reserve the right to shut down any projects that we deem as unsafe. We want the event to be awesome and electrocution or other physical injury is not so great. Please bring your own fuses if you intend on working with the mains or otherwise high voltage project. Railguns, coil guns or any other projects with weapons are prohibited. Projects such as an induction furnace are similarly prohibited for an obvious fire hazard.

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

MakeOHI/O is hosted by OHI/O and the Electronics Club here at OSU. We’re also partnering with BMES this year to incorporate Bio-Hack into MakeOHI/O. You can find more information about OHI/O and our other events at


Without our sponsors and supporters, MakeOHI/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.

MakeOHI/O is Virtual! That means this year’s access to hardware is brand new. On February 12th via the Discord platform, challenges will be announced and teams will be given access to a Kit Builder website. Teams will have the weekend to evaluate the challenges, their hardware budget, and select from a list of components to create their hardware kit. That hardware will serve as all the materials used for your MakeOHI/O project.

Things to know:

  1. Only one kit may be built per team.
  2. Challenges to be announced on Feb 12th
  3. The kit building site will be open from Feb 12th at noon - 14th at midnight. You may update your kit by submitting another order. We will use the last order placed as your final choices.
  4. If you Register to participate after the kit building window you must join a team that has already built their kit or form a team with the expectation that your team will provide 100% of their own hardware.
  5. Kits will be picked up between March 1st and 4th at Dreese 2015 Neil Ave, Columbus, OH 43210
    • You must designate One Team member to pick up your kit and swag
    • Make sure that a team member receiving the hardware has access to a microphone and camera as judging this year will be in the form of video submissions.
    • You will receive a sign up link to schedule your pickup via Discord on Feb 12th.
    • If your entire team lives more than 30 miles outside of campus shipping arrangements can be made for your hardware by emailing
