The Ohio State University’s annual makeathon.

In-person at Fontana Labs and online

March 28 – 30th, 2025

WELCOME TO MAKEOHI/O

In March, join us at MakeOHI/O—Ohio State University’s largest makeathon—for a weekend of hacking hardware and creating real projects with awesome people. Over 250 undergraduate and graduate students will design, build, and demonstrate projects to a live audience of students, faculty, and representatives from tech companies.

At MakeOHI/O, we bring the Entrepreneurial Mindset to life with the KEEN framework. By focusing on Curiosity, Connections, and Creating Value, this makeathon is all about exploring innovative ideas, combining different concepts, and creating projects that really make an impact. It’s not just about the hands-on building—it’s about tackling challenges in creative ways, teaming up with others, and building something amazing!

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.

Description: The MakeOHIO 2025 AEP Challenge invites students to harness the power of technology and innovation to enhance safety and efficiency using sensors. In an era where smart technology is becoming increasingly integral to our daily lives, this challenge encourages participants to develop solutions that can detect abnormal conditions and promptly generate alerts or notifications. By focusing on the application of sensors, this challenge provides a unique opportunity for students to apply their programming, engineering, and analytical skills to real-world problems. The projects can range from simple detection systems to more complex control mechanisms, allowing participants to tailor their approaches based on their experience levels and interests. The challenge is to use sensors to detect an abnormal condition and then to generate an alert or warning notification to a user. Depending on the experience level of the students, their project could take on many different approaches and levels of complexity. With a variety of potential applications, including water leak detection, temperature control, and audio alerts, students are empowered to explore creative solutions that can improve safety and contribute to smarter environments. We look forward to seeing the innovative ideas and projects that will emerge from this challenge, showcasing the next generation of technology-driven safety solutions.

Prize: Four $250/$100/$50 Amazon Gift Cards for 1st/2nd/3rd, respectively

Description: Participants will simulate metal forming using plasticine, implement machine vision systems to analyze the geometry of the forged part to ensure it meets specifications, and measure strain in real time, comparing with predicted strain values, to mirror the process of creating forged-quality parts.

Description: We’re in search of bold new thinking. This is an invitation to solve the problem of medical error that harms millions of U.S. patients, kills approximately 250,000 patients, and costs billions of dollars every year. We’re calling on MakeOHI/O teams to envision the best consumer-driven patient safety tech solution that has the potential to avert patient harm and save lives.

In order to be eligible to win your innovation must be consumer-driven (versus designed for clinical staff use) and address with one of the following five leading patient safety challenges facing health care across the continuum of care: Medication errors, procedural/surgical errors, errors during routine patient care (e.g. pressure ulcers, blood clots, falls), infections and diagnostic safety. The winning team will represent the most aligned, innovative, impactful idea that clearly understands the problem identified.

Prize: $400 worth of gift cards to the best team

Frequently Asked Questions

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!

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/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.

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 for MakeOHI/O.

Registration is open now! If you want to be eligible to receive a hardware kit, you must register and have a team before the event. If you have any questions, feel free to reach out to hackathon@osu.edu.

All participants must be in teams of 2 to 4 to submit a project, 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.

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 pickup opens so that you have a better idea of what hardware to choose for your kit.

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 provided. Please see the hardware page for details on what hardware will be available at the event. Hardware will be available at the event venue during the event.

MakeOHI/O 11 is transforming its project submission and judging process to provide a dynamic and interactive experience for participants and judges alike. This year, teams will present their projects in virtual Zoom breakout rooms, each hosting up to 12 teams for a 4-minute presentation followed by a Q&A session. Whether choosing a live demo or a video demonstration incorporated into presentation slides, each team will have the opportunity to showcase their project’s innovation and impact. On presentation day, Zoom links will be distributed, and teams are required to join their designated breakout room promptly. For more detailed information on the submission process, presentation preparation, and judging criteria, please visit this link. Remember – the competition is only a small part of the event! The most important part is to have fun and build something amazing.

Even something as small as a relay controlling a lamp being on could be hazardous with exposed wires. For safety 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. For more information regarding what technical resources are allowed, click here!

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 or sign up here!

MakeOHI/O is hosted by OHI/O and the Electronics Club here at OSU. You can find more information about OHI/O and our other events at https://hack.osu.edu.
