Mind Synchronizing Generator

This machine can trigger epileptic seizures and should be avoided

at all costs by anyone who suspects even slightly that they are
epileptic.

Your Mind/Synchronizer is designed to be a completely self-contained

unit with built in batteries. The system produces a variable rate flashing
mono chromatic directional "shaped" light source and complementary
synchronized audio pulser with tone "shaping" control. The unit may be
used so that a group can be exposed to the light and sound pulses. For
individual use headphones can be used along with special assembled
light glasses. These are shown made from an existing pair of sun
glasses. Optimum performance requires a quiet and reasonably low
light condition. Distractions must be at a minimal.
The Mind/Synchronizer can produce strange and bizarre hallucinations
as well as providing a sense of relaxation and well being.

Information on Mind Control

Today's work environment demands that we have the ability to excel, to
compete and resolve problems. Hence, the most important tool we possess is our mind. To optimize your
potentials we now offer our low cost mind synchronizing unit.
After 25 years of research, Doctor Axel Bruck of Berlin, Germany, created a machine that can enhance,
develop and perfect the qualities within you in order to attain your goal - mental fitness.
It has been found that mental reaction by external stimulation in people is either active or passive. The
Mind/Synchronizer can determine automatically the kind of person you are. Evaluation is performed via
means of a hand sensor through a technique called Biofeedback that is sensitive to the flow of blood.
This knowledge is very important for providing optimal stimulation to the users. Having determined the
kind of person you are, the Mind/Synchronizer now uses "programmed" light pulses and "shaped” sound
to encourage reaching a required mental condition, be it relaxation or efficiency. It has been known for
hundreds of years, that an external rhythm of light and sound has an effect on your mental condition. The
Mind/Synchronizer is a modern version of a drum and a flickering fire place.

Through extensive scientific measurements, experiments and results, the Mind/Synchronizer is able to
improve your performance level by means of selection of the right stimuli for the individual user to

achieve:
(a) Deep Relaxation
(b) Relaxation
(c) Equilibrium
(d) Activation
(e) Efficiency
Whether in sports, professions or personal lives, the development of personality and identity is vital to
personal success and satisfaction. The Mind/Synchronizer trains and perfects your mental and psychic
abilities so that you have a stable way of thinking along with a healthy outlook. The Mind/Synchronizer
teaches you the technique of concentration, stress handling, focusing, visualization, relaxation and self
consciousness.
When using the Mind/Synchronizer you learn to set a goal and concentrate on this goal completely. You
switch off all distractions and thereby hold your concentration over a long period of time. By so doing,
you improve your power of concentration. In the long run, you will think clearly, make better decisions
and deal more effectively with life itself.

The program of Relaxation combats stress, tension and direct pressure. Almost everything we do causes
stress. Stress means that the body is in a chaotic condition. The opposite of stress is relaxation. The
right kind of relaxation is an optimization of mind, concentration, learning ability, performance and health.
In reality, a relaxed person saves more than half a billion heart strokes over a nervous or hectic person,
according to Professor Prinzinger's theory of the Quiet Pulse. The body consumes fewer energy; organs
are burdened less; and life expectancy Increases.

The program of Efficiency is a newly developed psycho active technique: the indication of unconscious
eye movements; and the employment of rhythm displacement. The combination of visual effects (flashing
LED) with audio input (head-set) produces high efficiency performance. The Mind/Synchronizer
establishes physical and mental readiness to attain this goal of high performance.

The program of Activation involves more optic with visual patterns than acoustic to provide "imagination
journeys". To experience associations with your own history and your own personality, you will be able to
discover your emotional condition and personality.

The program of Equilibrium allows for meditation with your eyes open. You would observe attentively,
simply and exactly each individual light source and its changes. The Mind/Syn9hronizer will bring you the
health balance you desire through light and sound.

Mind machines are available by a wide variety of names today. Often referred to as hemispheric
synchronizers or Cortical frequency entertainment devices, they all basically perform one basic function;
they lead the brain to synchronize both hemispheres, then lead those synchronized hemispheric
frequencies to a specific "target" frequency. In order to understand why anyone would want to do such a
thing, let’s examine what frequencies the brain produces and what people experience when the brain is
at these frequencies.
There are generally four different levels that brain waves are broken down into. They are referred to as
Beta, Alpha, Theta, and Delta. With respect to frequency, they look like this:
Beta: 13 cycles per second or more
Alpha: 8 to 12 cycles per second
Theta: 5 to 7 cycles per second
Delta: 1 to 4 cycles per second
There are profound changes in a person's conscious experience at each of these levels. The Beta
frequency is the "normal" waking frequency, the drive-in-the-city go-to-work-drink-coffee frequency, and it
can range as high as 40 cps. It is not a relaxing frequency.
The Alpha frequency is a realm of relaxed awareness. It has been shown in concrete fashion to be
associated with increased capacity for learning, comprehension and retention. It is in the alpha state that
the best learning occurs.
Theta is a hypnotic state often associated with meditation, a zen-like state of waking dreaminess. It can
be a profoundly relaxed state where internal associations and thoughts can form ideas with clarity that
could never have emerged in the normal high noise environment of the Beta state. This is also the range
that many native Shamans have been found to enter when engaging in healing trance work. It is a state
of profound tranquility.
The Delta state is much simpler to define; you're asleep. When your brain waves are in the Delta range,
you're in a sound and restful sleep.

A number of studies have been done that indicate that a flashing light has a profound impact on the
entire brain, more so than a pulsing sound or feeling. When the brain is exposed for a time [as short as
two to five minutes] to a flashing light at a speed close to the brains existing "operating frequency", the
brain will begin to synchronize with the stimulation. Moreover, both hemispheres, which are often
operating at different frequencies, will harmonize. This has also been shown clinically and statistically
to be an aid to mental functioning. There are many books on the market on this subject for anyone who
would like more detailed information on these studies.

Operating a Mind Machine

Now with the previous in mind, the operation of the mind machine in all of its forms is basically the
same; Start the machine off at a frequency that is roughly equivalent to the operating frequency of your
brain at the time [use your own feelings as a gauge - if you're frazzled, start at maximum frequency, if
you're pretty mellow, start at about half frequency]. Allow yourself about three to four minutes at this
frequency. Now begin slowly bringing the frequency down, very slowly. You should take about seven to
ten minutes to bring the control all the way down. When you reach a minimum, leave it there for about
five to seven minutes.

After you've gotten to the bottom range, you can either lead yourself back to normal, in which case you
will feel somewhat like what you may consider a "good normal". If you so choose, you can exit directly
from the lowest setting. If you do and you have taken your time in getting to it, and stayed there for
several minutes, you will notice that it may be very hard to begin to move. Your limbs may feel very
heavy, as if your body were asleep. If you manage to get to your feet, you may notice that things won't
feel as solid-they'll seem to have a rubbery quality to them. These sensations can be quite pleasant as
long as you're prepared and expect them [and don't have to drive or operate heavy machinery
afterwards!].

The visual effects are the most stunning, and can only be likened to the experience of ingesting certain
mind altering substances. As the frequencies change, you will notice colors! Yes - two little flashing red
lights in front of your closed eyes will create the illusions of fantastic, swirling colors, geometric designs
ranging from ultimate simplicity to incredible complexity. One effect will be observed as myriads of little
shapes that form and begin to slowly spiral around your field of vision, first clockwise, then
counterclockwise, then back again. You will see dreamy, smooth, cloudlike fields of frosty blue-white,
deep blues, deep reds, electric greens, yellows, whites, purples, all in balls, stripes, liens and stars,
triangles, dancing and moving like the most intense kaleidoscope you can imagine. The imagery is
absolutely fascinating and can transfix you with the dazzling display. You will be absolutely amazed and
impressed with the fact that it is your brain that produces this light show.
This unit is designed to take you from a medium level Beta down to a low Theta. You can use these
states as you desire. You may wish to stop the frequency decrease early and remain in the Alpha state
before an exam, prior to entering a class or trying to learn something important to you. You can continue
on down and enter the Theta level and create healing imagery in your mind as an assistance to your
body's won natural healing create healing imagery in your mind as an assistance to your body's own
natural healing processes.
Most of all play with your unit and enjoy the show. Built right, it will provide many years worth of reliable
service. You will become familiar with the settings and will be able to use the machine in a way that's

exactly right for you. Always leave yourself plenty of time to use the machine and at least a half hour
after to "normalize". Use the unit to help you drift off to sleep - you can actually lead your brain down and
turn the unit off after you've gone into a deep Theta and if you're ready to sleep away, it's only a short
slide from theta into the peaceful slumber of Delta.

Circuit Theory (reference figure 29-2)

Integrated circuit (I1) is an a-stable oscillator with pulse rate being controlled from approximately 3 to 40
reps per second by external pot (R2).
The output of Ul now triggers integrated circuit (I2) being connected as a mono-stable that controls the
ratios of "on" to “off” time of these pulses. This duty cycle control is via external pot (R5). Light emitting
diodes (LEDl,2) are connected to the output pin 3 of I2 thru brightness control pot (R 7). These are the
diodes you install in the sunglasses or can be a single ultra-bright LED for group use. The result is a
variable flash rate from 3 to 40 pulses per second with a variable duty cycle rate [ratio of on time to off
time]. Note duty cycle setting is best experimented with and recorded as to effect.
The circuit also includes integrated circuit (I3) connected as a variable rate sonically "shaped" audio
oscillator. Output is via Jack (J2) driving a set of 32 ohm headphones.
The feedback circuit consists of two external pieces of metallic tape providing points of contact by the
user’s hand. Body resistance now partially controls the pulse rate of I1. An "up tight" situation provide
lower contact resistance and consequently raises the pulse rate. As one relaxes this resistance becomes
higher and lowers the pulse rate. An external Jack (J3) provides for connection of other bodily contact
probes to the feedback system. These contact probes are left to the discretion of the user. This jack is
omitted when using the external tape probes.
Switch (S1) control powers to the circuit and should be “off' when not in use to conserve the internal
batteries.

Assembly Board
1. Layout and identify all parts and pieces. Verify with parts list, separate resistors as they have a color
code to determine their value. Colors are noted on parts list.
Figure 29-3 Assembly board

2. Fabricate a piece of .1” grid perforated board to a size of 6 ¼ x 1 ¼ inches as shown figure 29-3. An
optional printed circuit board is individually available.
The circuit is shown built using the more challenging perforated circuit board often required for a science
fair project. A printed circuit board is individually available and requiring that you only identify the

 6

particular part and insert it into the respective holes as noted. The printed circuit board is plainly marked
with the part identification. Soldering in now very simple as you solder the component leads to the
conductive metal traces on the underside of the board.

The perforated board approach is more challenging as now the component leads must be routed and
used as the conductive metal traces. We suggest that the builder closely follow the drawings on this
section and mark the actual holes with a pen before inserting the parts. Start from a corner using as a
reference and proceed from left to right. Note that the perforated board is the preferred approach for
science projects as system looks more homemade.
3. If you are building from a perforated board it is suggested to insert components starting in the lower
left hand corner as shown figure 29-3. Pay attention to polarity of capacitors with polarity signs and all
semiconductors. Resistor RI2 is connected from the pin of 11 to the PC board. Note the control pots
R2,5,7,9 and jacks J1,2,3 should be positioned to closely match the holes as shown on figure 29-5.
Route leads of components as shown and solder as you go cutting away unused wires. Attempt to use
certain leads as the wire runs or use pieces of the #24 buss wire. Follow dashed lines on assembly
drawing as these indicate connection runs on underside of assembly board.
4. Attach external leads to battery holder as shown.
5. Double check accuracy of wiring and quality of solder joints. Avoid wire bridges, shorts and close
proximity to other circuit components. If a wire bridge is necessary, sleeve some insulation onto the lead
to avoid any potential shorts.

6. Assemble light emitter diode to cable PI as shown. Retrofit to eyewear as per figure 29-4.

7. Fabricate the enclosure tube (TUB1) as shown figure 29-5 and insert assembly board and battery.
Verify that controls as mounted on the assembly board will match the drilled holes with dimensions as
shown. Note the dimensions are shown for use with the optional printed circuit board and may be
changed. Unit is secured by nut attaching the adjustment pots.
