In this article, I propose to consider the creation of a device rather quickly (~ 30 seconds) that introduces a person into a state of trance or a hypnotic state.
Recently, a number of articles devoted to lucid dreams have appeared on the habr.
And I thought that my research in this area could be interesting to others.
It all started with attempts to scientifically describe and explain the phenomenon of lucid dreams, or in other words OS. Why did I have to do a lot of experiments on myself and others. As a rule, these experiments were painless although exceptions occurred. In the end, I happened to get to know the guys who were doing this research more thoroughly. In particular, the children turned out to have an electroencephalograph (hereinafter referred to as EEG), with the help of which the EEG of the work of the human brain during a lucid dream was taken.
To determine the moment of the dream, the dreamer was given a certain task, which he had to fulfill in the dream and which was easy to read by EEG, in particular, to look left and right sequentially. This action was easily determined by the temporal electrodes.
In fact, it turned out that the dreamer's EEG in a lucid dream almost completely coincides with the waking person's EEG. The information turned out to be interesting but not giving any practical application.
EEG also showed that calmer people, like people in a state of meditation, have distinct patterns of the work of some parts of the brain, namely signals with a frequency of ~ 8-12 hertz. It looks something like this:
In parallel, I received information from various kinds of spiritual practitioners that in order to enter a state of trance / lucid dreaming, it is necessary to relax and stop the internal dialogue.
After that, the idea began to creep in that the key to enter the meditative state is in synchronization with the work of some parts of the brain at a frequency of ~ 8-12 hertz. Experiments in this area have begun. Starting from electric shocks with a given frequency to other more sophisticated methods.
The solution was found by chance - having stumbled upon a wikipedia article about a dream machine invented in the past. The essence of the invention was that a cylinder with slots revolved around the light source. Thus, giving out a flicker frequency of about 12 hertz. The result was a simple way to perceive the play of colors and dreamy images.
The question remained - how to relax the muscles. It so happened that most modern people live in constant stress and muscle clamping is the norm. For these purposes, I tried cheap Chinese devices designed not only for weight loss, not for "lazy muscle swing." Which forced to compress-unclench muscles using current pulses. The inconvenience of these devices was the need to use conductive gel.
Such a detail from my point of view was not very convenient.
In the end, I thought - muscles relax during massage. Now, if you find a masseuse who will massage the muscles with a frequency of 12 hertz, this will simultaneously allow them to relax, and also serve as a source of synchronization for the brain. In the end, I decided to make a belt with an attached vibro motor that could be mounted on arms and legs.
In total, we got two channels of incoming information that we can control. For greater efficiency, I decided to still use modulated sound at a given frequency. In fact, a person is not able to hear a sound with a frequency of 12 Hz. To solve this problem, I decided to use the carrier frequency or just a monotonous melody, the volume of which will change with a frequency of 12 Hz.
So, from the theoretical model I moved to the practical one. A device was developed that synchronously produced light, vibration and sound signals with a continuously adjustable frequency.
The device diagram is below:

Microcontroller program (can be downloaded at the link below):
The device itself: The
vibro part was assembled on the basis of electric motors from a CD drive and an adhesive plaster drum.
A study on friends showed that 7 out of 8 friends who were available began to see all sorts of images, including realistic dream pictures.
In the case of using LEDs in glasses - the images, as a rule, for some reason turned out to be square.
The device itself was used to train direct entry into lucid dreaming. Those. to enter dreams directly from a state of wakefulness without loss of awareness.

PS The audio connector works in key mode which smoothly turns on and off.
I would be grateful for suggestions for improvement.
