Thanks for posting your sequence. Taking out the short amount of Beta after Theta starts was a good idea.

I like your idea of making a sleep mask. Please be careful with wires while you’re asleep, since if you roll over you want to ensure that it won’t limit the amount of oxygen you take in — I’d hate to see you wake up dead!

I’m working on a more complex version of the Brain Machine that is specifically for helping people sleep. Like your proposed project, mine will use a comfortable fabric sleep mask and use surface mount LEDs. I’ll have all the electronics sewn into the mask, including a rechargeable battery and small speakers. The firmware for this version will use PWM to enable the sound to fade out at the end (as well as independently vary the amplitude of all of the generated brainwave frequencies during the sequence).

All the best with your project!
Mitch.
