Would you consider explaining how to build one?

ChristianMarks said in one of his comments that he believes the device has allowed him to overcome a bias in the valley against hiring older engineers. Why would he want to reveal the details of a device that if widely used could erode his advantage?

At first I wasn't going to mention this (lest it become the reason he doesn't share the details), but then I realized, here's a smart guy who has a device that makes him even smarter, so I figure he probably already knows. :)

Perhaps it's because most people aren't purely self interested.

I just found this and...I'm curious about how well it works.

Really, really curious.

EEG is the opposite of TDCS. EEG listens for brain waves, tdcs runs a current through your skull.
