For years, I’ve been interested in human brainwaves, especially the possibility of using nonlinear dynamics (“chaos theory”) to analyze them. But affordable EEG devices simply have not been available. Back in the early 90s, I built a little device from a kit, but the data had only 6-bit resolution, and there were issues with signal-to-noise ratio, so I didn’t make any progress.
But now, we have Emotiv, a company that intends to bring high-resolution brainwave data to the desktop. Their first consumer-grade neuroheadsets rolled off the assembly line and shipped last week, and I was fortunate enough to receive mine on Tuesday. So here’s a little tour of what we know so far.
The device arrived from the Philippines in a compact box. Shipping had been delayed by Typhoon Morakot, the deadliest typhoon to hit Taiwan in recorded history.
Here’s how it shipped:

Here’s a shot with the cat, for scale:

Here it is, fully revealed:

And now for a gratuitous montage of movies that inspired me to go down this path.
It took some figuring out, but we finally got the neuroheadset on the the right way. Okay, it was my wife who said we had it on backward. YOU WERE RIGHT, HONEY
My friend Scott applies the saline solution to the electrodes. Liberally.
