[Lady Ada] over at Adafruit just did a delightful tear down of the Muse EEG headset.
The Muse headset is a rather expensive consumer-grade EEG headset that promises better meditation with the ability to track your brainwaves in order to go into a deeper trance. We’re not much for meditating here at Hackaday, but the EEG sensors really do work. It’s pretty cool to see the insides of this without forking out $300 ourselves for one we might break.
Like most EEG headsets, they weren’t really designed to be worn while sleeping. Two bulky pods over the ears hold the battery and charging circuit on one side, and the brains on the other. The neat part about it is a little adjustable metal piece which allows for adjustment on the strap while maintaining all the electrical connections. A flexible circuit houses forehead electrodes which go along the length of the band.
In the past we’ve seen work done on the Lucid Scribe project, using a modified Neurosky Mindwave EEG (at $99 it’s much cheaper to hack). The idea is to be able to monitor your sleep cycles accordingly, and then give audible cues to the dreamer in order to “wake up” inside the dream. Think of the Inception music.
Unfortunately it doesn’t look like the Muse will be any better for lucid dreaming. If you were able to decouple the electrodes from the rest of the headset, then it might just work.
