Hey guys. A little while ago I took a trip to the Museum of Science and Industry in Chicago and ever since I’ve been fascinated with their “mindball” game and was thinking about making my own. It isn’t very difficult in principle: Two players with EEG headsets sit opposite each other and the data is used to determine the location of a rolling ball on a table.
I saw that the actual mindball headset is for sale here, but for $300 USD I’m not sold. Plus I’m not even sure what the output is on that cable.
I saw that there are other solutions available such as hacking some neurosky headsets, but I’m not a fan of the earlobe earth solution that they all seem to use. I’m willing to sacrifice some accuracy for ease of use here. That’s one of the reason I like the mindball band so much: It’s really, really bare bones.
I could make my own EEG headset, but that really seems like a lot of effort for something that will end up very ugly and I want to focus on the table itself anyway. I’m thinking one Arduino per headset connected via hub to a Raspberry PI. The PI could use the headset data and talk to another Arduino controlling the ball.
Any suggestions on what to do with the headset situation? Maybe the Heart/Brain SpikerShield with the neutral electrode built into a custom band instead?
