MakerX is a Columbus area Maker Exposition. It was February 29 from 10-4 pm at the Ohio Expo Center and they had 68 groups this year showing what they do or have done. It ranges from projects by young kids, to school groups, to hobbyists, to University departments, to startup and established companies. I have been to a few Maker Faire’s in different cities and it was in the middle, sizewise. There were a nice variety of displays. The venue was large enough so there was room to move or stand. Lots of great conversations happened with exhibitors sharing their projects.
There were some battling robots, some AWESOME furniture made by Riverdale students. R2D2 was there, but so was a friend of his.
Some things that I saw there and need to research are digiRacer, a SoapBox Derby project by mimicobots and some craft stick connectors called “nurcs” (they kinda look like knex connectors, but for craft sticks).
