Mitch Altman's "Brain Machine"

[Dingus]

I recently thought of making a "Brain Machine" that I read about on Make.com, and I was wondering if anybody here had made one before and if you'd recommend it. If anyone has a better suggestion, I'd love to hear it, but for the most part I don't think I'll be making anything more complex than this.

Ok, I finally bought, made and tried the thing, but I've been having a hard time finding a frequency that would be useful for hypnosis. and suggestions for the frequency?

Fluctuate between 4 and 8 Hz.

The only problem with getting the correct frequencies is that they are below the audible levels of the human hearing.Humans can only hear as low as 20hz ( if you've have good hearing ).

So freqeunices below that have to be done by using a different frequency on each ear with the difference between them about the same as the frequncy you want.

Tyr this link for all the theory on it.

It uses LED's, so being below audible levels isn't exactly a problem.
