Videos from Events


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!

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 register for MakeOHI/O! What's the timeline?

Registration is open! 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

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 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.

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 for 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 pickup 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!

How are projects judged?

MakeOHI/O 10 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.

Are any projects not allowed?

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!

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

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


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.

Ohio State Digital Union

Human-Centered Computing

Wearable Sensors for Measuring Core Stability [Google Doc]
Description: Core stability encompasses the acts of aligning the body with respect to gravity and maintaining, achieving, or restoring the body center of mass relative to the base of support or, more generally, within the limits of stability during daily activities. Quantifying core stability is relevant to several clinical applications, including individuals suffering from Alzheimer’s, Parkinson’s, epilepsy, and brain injury. Today’s “gold standard” in monitoring core stability is camera-based motion capture, which is, unfortunately, constrained to laboratory environments. This challenge is seeking a wearable solution for measuring core stability in a reliable, accurate, low-cost, and seamless manner.
Prize: Raspberry Pi Kits for each team member for top team. Top 3 teams will be showcased at the April 1 Human-Centered Computing Workshop


Prizes are distributed per team member—each member of a winning team will get their own prize.
